  Background: During pregnancy and early motherhood, risks of relapse and worsening are high for women with a history of eating disorders (EDs), as are adverse sequelae for their babies. However, systematic descriptions of the processes that these women undergo through pregnancy, birth, and early motherhood are lacking, as are good descriptions of the various trajectories these women follow through pregnancy and early motherhood. This study addresses both these knowledge gaps. Methods: We used a longitudinal research interview design, recruiting a non-clinical sample of 24 women with a history of severe EDs from routine pregnancy controls in five public, local, family health care centers in Norway. The participants were interviewed twice, first during pregnancy and then 4–6 months after delivery. Data were analyzed according to grounded theory. The focus was on modeling the trajectories of EDs through pregnancy, birth, and early motherhood. All the participants were diagnosed (DSM-5) using the Eating Disorder Examination and then completed the Eating Disorder Examination Questionnaire. Results: Five perceived trajectories through pregnancy and early motherhood were identified: “The mastering mother,” in which an ED pathology seems to be absent through pregnancy and early motherhood; “The inadequate mother,” in which the ED pathology worsens before pregnancy, through pregnancy, and early motherhood; “The overwhelmed mother,” in which the ED worsens during pregnancy and early motherhood; “The depressed mother,” in which the ED is put on hold during pregnancy, but worsens in early motherhood; and “The succeeding mother,” in which the ED worsens during pregnancy, but reduces in early motherhood. Discussion: ED trajectories through pregnancy and early motherhood vary greatly among women with a history of EDs. This may indicate different psychological dynamics through these phases. A model with five trajectories captures a large degree of the variation. The model may help clinicians’ preparedness when dealing with these patients.

  Objectives The aims of this study were to investigate modifications in pain sensitivity after RYGB and to explore associations between pain sensitivity and weight loss, chronic abdominal pain, total body pain, anxiety, depression, and pain catastrophizing. Methods In total, 163 patients with obesity were examined with a cold pressor test for pain sensitivity before and two years after RYGB. Two aspects of pain sensitivity were registered: Pain intensity (numeric rating scale, range 0–10) and pain tolerance (seconds). Associations between pain sensitivity and the explanatory variables were assessed with linear regression. Results Two years after RYGB the pain intensity increased (mean ± SD 0.64 ± 1.9 score units, p<0.001). Pain tolerance decreased (7.2 ± 32.4 s, p=0.005). A larger reduction in body mass index was associated with increased pain intensity, β=−0.090 (95 % CI −0.15 to −0.031, p=0.003), and decreased pain tolerance β=1.1 (95 % CI 0.95 to 2.2, p=0.03). Before surgery, participants with chronic abdominal pain reported 1.2 ± 0.5 higher pain intensity (p=0.02) and had 19.2 ± 9.3 s lower pain tolerance (p=0.04) than those without abdominal pain. No differences in pain sensitivity were observed between participants who did or did not develop chronic abdominal pain after RYGB. Pain sensitivity was associated with symptoms of anxiety but not with pain catastrophizing, depression or bodily pain. Conclusions The pain sensitivity increased after RYGB and was associated with larger weight loss and anxiety symptoms. Changes in pain sensitivity were not associated with development of chronic abdominal pain after RYGB in our study.

  Background: There is a higher prevalence of eating disorders among women seeking in vitro fertilization (IVF). Women with a history of eating disorders may be particularly vulnerable to eating disorder relapse during IVF, pregnancy, and early motherhood. The experience of these women during this process has hardly been studied scientifically, despite its high clinical relevance. The overall aim of this study is to describe how women with a history of eating disorders experience the process of becoming a mother through IVF, pregnancy, and the postpartum period. Methods: We recruited women with a history of severe anorexia nervosa who had undergone IVF (n = 7) at public family health centers in Norway. Semi-openly, the participants were interviewed extensively first during pregnancy, and then 6 months after birth. The 14 narratives were analyzed using interpretative phenomenological analyses (IPA). All participants were required to complete the Eating Disorder Examination Questionnaire (EDE-Q) and were diagnosed (DSM-5) by using the Eating Disorder Examination (EDE), during both pregnancy and postpartum. Results: All participants experienced a relapse of an eating disorder during IVF. They perceived IVF, pregnancy, and early motherhood to be overwhelming, confusing, a source of severe loss of control, and a source of body alienation. There were four core phenomena that were reported that were strikingly similar across all participants: “anxiousness and fear,” “shame and guilt,” “sexual maladjustment,” and “non-disclosure of eating problems.” These phenomena persisted continuously throughout IVF, pregnancy, and motherhood. Conclusion: Women with a history of severe eating disorders are highly susceptible to relapse when undergoing IVF, pregnancy, and early motherhood. The process of IVF is experienced as extremely demanding and provoking. There is evidence that eating problems, purging, over-exercising, anxiousness and fear, shame and guilt, sexual maladjustment, and non-disclosure of eating problems continue throughout IVF, pregnancy, and the early years of motherhood. Therefore, it is necessary for healthcare workers providing services to women undergoing IVF to be attentive and intervene when they suspect a history of eating disorders.

  Older adults face age-related changes as well as stigma in relation to their bodies and sexuality, challenging their understanding of themselves as sexual, thought to impact both sexual desire, activity and satisfaction. A qualitative study with a semi-structured interview was completed with 32 people, aged 65–85, to investigate how older people construct understanding of their self as sexual in an ageing body. The analysis generated two main themes; “Positions of the ageing body as sexual”, with three subthemes, and “Negotiating change, transitions in identities”, with two sub themes. Results showed variations in participants’ thoughts about their body and how either appearance, agency or body function influenced different aspects of current sexuality and sexual satisfaction, and understandings of self. Statements showed examples of both internalized ageist understandings of the ageing body as sexual, but also rejections or low relevance of ageist attitudes in the understandings of present body image and sexual satisfaction. Results showed differences in how changes were understood and negotiated either through enhancement strategies or through cognitive-emotional, and social regulation. The findings demonstrated paradoxes and contradictions in the understanding and management of the ageing body and sexual satisfaction, where variations were found along but also across the divides of gender, relationship status and quality, sexual orientation, self-esteem and age cohorts. Implications indicate that health care strategies and policies should understand sexual ageing from a developmental perspective to support individual projects of developing affirmative and adjusted identities as sexual in an ageing body.

  Background Increasing physical activity and limiting sedentary time may minimize weight recurrence after bariatric surgery. However, few studies have evaluated potential associations of objectively-measured physical activity and sedentary time with post-surgical weight recurrence over time. Aims To evaluate associations of change in physical activity and sedentary time with weight recurrence after bariatric surgery. Methods Participants from the Oslo Bariatric Surgery Study, a prospective cohort study, wore an ActiGraph monitor for seven days at 1- and 5 years after surgery to assess daily physical activity and sedentary time. Participants’ weight was measured at in-person clinic visits. Chi-square Test and Paired-samples T-test evaluated group differences and change over time, while Pearson’s Correlation, multiple logistic and linear regression investigated associations between variables. Results Five years after surgery 79 participants (70.5% response rate, 81% female) (mean (sd) age: 54.0 (±9.3), BMI: 32.1 (±4.7)) had valid monitor data. Participants increased their sedentary time (71.4 minutes/day (95% CI: 54.2–88.6, p = <0.001)) and reduced daily steps (−1411.1 (95% CI: 737.8–208.4), p = <0.001), light physical activity (−54.1 min/day (95% CI: 40.9–67.2, p = <0.001)), and total physical activity (−48.2 (95% CI: 34.6–63.3), p = <0.001) from 1- to 5 years after surgery. No change was found for moderate-to-vigorous intensity physical activity. No associations were found between changes in steps, physical activity or sedentary time and weight recurrence. Conclusion Participants increased sedentary time and decreased light- and total physical activity between 1- and 5 years post-surgery. Overall, changes in physical activity and sedentary time were not associated with weight recurrence. Interventions to help patients increase physical activity and limit sedentary time after bariatric surgery are needed.

  Purpose Head and neck cancer (HNC) patients are at risk of long-term body image distress (BID). We aimed to investigate the severity of BID in long-term HNC survivors and to explore the associations between sociodemographic and clinical factors, patient-reported late effects, and cancer-related body image (BI) concerns. Methods This cross-sectional study included quality of life and BI assessment in an 8-year (SD = 1.58) follow-up after treatment among 258 HNC survivors. Multinomial logistic regression analysis was used to investigate the relationship between three groups of BI concerns (no concerns, mild to moderate concerns, and BID) and patient-reported late effects. Sociodemographic and clinical variables were included in the model as covariates. Results A total of 51.2% of participants had mild to moderate BI concerns, and 9.5% reported BID. Compared to those with no BI concerns, participants with BID were more likely to live without a partner, to have had radiotherapy and surgery, and to report worse emotional functioning and higher oral and throat pain. Compared to participants with no BI concerns, those with mild to moderate concerns reported higher oral and throat pain and speech problems. Conclusions Some level of cancer-related BI concerns persisted in the majority of HNC survivors many years after treatment, while a small proportion of survivors experienced BID. BI concerns were associated with treatment modality and patients’ daily functioning and symptoms. Implications for Cancer Survivors Insight into factors associated with BI problems may help to identify survivors at risk and may facilitate closer follow-up of survivors in need.

  This study explores the connection between relationship duration and feelings of closeness in Norwegian men and women, and the association with sexual satisfaction and activity. A sample of 4160 Norwegians aged 18–89 years was enrolled from a randomly selected web panel of 11,685 Norwegians. This study focused on participants who were married or cohabiting (1432 men, 1207 women). Closeness was the highest for men and women who had been with their partner for 0−6 years. However, among those who had been with their partner for 31 years or longer, men felt closer to their partners than women. Irrespective of relationship duration, the most important factor for both men and women’s perceived closeness with their partner was general sexual satisfaction. Among men who had lived with their partner for 7−20 years and 31 years or longer, having been monogamous in life was significantly associated with “inclusion of others in the self” (IOS). Further, closeness was associated with higher intercourse frequency, lower masturbation frequency, and satisfaction with genital appearance in men who had been with their partners for 31 years or more. Intercourse frequency was significantly associated with IOS in women who had been with their partner for 0−6 years. Furthermore, in women who had been with their partner for 31 years or more, satisfaction with their own weight was important for IOS. In conclusion, men and women reported similar degrees and patterns of IOS up to the point where they had been in their relationship for more than 30 years. Thereafter, women reported feeling less close to their partners, while men’s feelings of closeness increased. This may be related to physiological, psychological, and social changes in the lives of aging men and women.

  Background: Being pregnant is a vulnerable period for women with a history of eating disorders. A central issue in eating disorders is searching control of one’s body and food preferences. Pregnancy implies being increasingly out of control of this. Treatment and targeted prevention start with the patient’s experience. Little is known about how women with a history of eating disorder experience being pregnant. Method: We interviewed 24 women with a history of eating disorder at the time of pregnancy, recruited from five public pregnancy controls at local family health centers in Norway. Interviews were analyzed by means of ideal type analysis, with a particular focus on how the participants experienced pregnancy and perceived triggers in possible experiences of relapse or worsening during pregnancy. All participants completed the Eating Disorder Examination Questionnaire (EDE-Q) and were diagnosed (DSM-5) by using the Eating Disorder Examination (EDE). Results: On becoming pregnant, 23 of the 24 participants experienced worsening or relapse of their disorder. This occurred both at first time and after several pregnancies, and either interviewed early or late in pregnancy. Ideal type analyses indicated seven different personal features associated with worsening or relapse: the “chaotic” “rigid” “perfect” “worried” “shameful” “motherhood fearing” and “the mother with lost identity” Perceived triggers of worsening or relapse were: “loss of control” “unpredictability” “competition” “change of appearance” “shame and nausea” and “loss of identity.” Conclusion: Pregnancy is a vulnerable period for women with a history of eating disorders. A great variation in personal psychological dynamics seems to interact with perceived triggers in worsening or relapse of eating disorder. Our findings have important implications in understanding mechanisms of relapse in pregnancy, preventing relapse and help tailoring adequate intervention.

  This paper aims to determine the prevalence of sending nude pictures/videos in the Norwegian population and investigates gender differences regarding consensual, unsolicited, and coerced experiences. Data were obtained from a probability-based web survey of 2,181 men and 1,967 women between 18 and 89 years old. The majority of participants expressed relatively accepting attitudes toward sending nude pictures/videos, and men expressed more positive attitudes than women. Twenty-nine percent of participants reported having lifetime experience with sending nude pictures/videos, and sending nude pictures/videos was more common in younger individuals than older individuals. More women than men claimed that they sent their most recent nude picture to a committed partner, and twice as many men than women had sent a nude picture to a stranger or a person they only had contact with on the Internet. In addition, more than twice as many women than men reported consensual sending nude pictures/videos, and more men than women sent unsolicited pictures/videos. Consensual sending nude pictures/videos was characterized by the presence of men and women within committed relationships. In Norway, sending nude pictures/videos seems to be a way of being sexual in the context of committed relationships.

  Abstract Purpose: After bariatric surgery, body contouring surgery (BCS) is thought to improve body image, weight loss, and mental health. Many patients desire but do not undergo BCS after bariatric surgery. This patient subset has rarely been studied. The present study compares bariatric surgery patients that, at 5 years after surgery, desires, have undergone or have no desire for BCS regarding pre- and post-surgery body image and mental health, including within-group changes over time. Materials and methods: Data were collected from participants (N = 216) pre-bariatric surgery and at 1- and 5-year post-surgery. Health care providers measured body mass index (BMI). All other data were collected via self-report (questionnaires). Results: At 5-year post-surgery, 30.6% had undergone BCS, 17.1% did not desire it, and 52.3% desired BCS. Patients who subsequently desired BCS scored lower on body satisfaction pre-surgery than the other groups. They also reported less resilience pre-surgery and more depressive symptoms at all times compared to participants with BCS. For five-year post-surgery, patients who desired BCS had lower body satisfaction levels than patients with BCS and were more bothered with excess skin relative to the two other groups. Body satisfaction improved in all three groups from baseline to five years and in most patients with BCS. Mental health improved only in patients with BCS. Conclusion: This study emphasizes the relevance of identifying participants who desire but have not undergone BCS. The study suggests that BCS is associated with improved body image and mental health.

  The purpose of this paper is to examine the extent to which Norwegians are satisfied with their singlehood, and to determine the association between being single and sexual activity. Data were obtained from a questionnaire survey of a representative web sample of 1,076 unpartnered individuals (568 women, 508 men) aged 18–89 years. A total of 45.2% of the single respondents reported being satisfied with being single, while 33.9% reported being unsatisfied. There was no difference between the age groups in men, but more women aged 45 years or older than women under the age of 45 were satisfied with being single. A higher percentage of gay, bisexual, and transmen than heterosexual men was satisfied with being single. More women who had not been sexually active with a partner in the past year were satisfied with being single than were women who had been sexually active. The men who were most satisfied with being single were those who had masturbated and/or had sexual intercourse, and least satisfied were those with no sexual activity, or exclusively masturbation activity. The results are discussed in terms of biological, psychological, and social positions.

  Patient satisfaction is viewed as essential for a successful outcome of bariatric surgery. Few studies have explored long-term satisfaction prospectively. This study aimed to examine pre- and post-surgery predictors for satisfaction with follow-up care, and change in outcome satisfaction from one to five years after bariatric surgery. A sample of 210 participants was recruited from a single treatment center. Self-reported and medical record data regarding mental and somatic health, body image, follow-up attendance, and weight loss were obtained before, one year, and five years after surgery. Over 90% of the participants were satisfied with the results and treatment one year after surgery, while 69% had their outcome expectations fulfilled and 62% were satisfied with the follow-up five years after surgery. A shift from initial satisfaction to unfulfillment of expectations was predicted by baseline body dissatisfaction, greater percentage of weight regain after initial weight loss, and more discomfort from somatic symptoms five years after surgery. In addition to symptom discomfort, worry about surgery predicted satisfaction with follow-up care. At five years, one-fifth of those initially satisfied reported that bariatric surgery had failed to meet their expectations. This suggests that outcome expectations related to weight loss, somatic symptoms, and body image need to be addressed both before and after bariatric surgery.

  A visible difference to the face or body may challenge adolescents’ adjustment and engagement in life activities, where some require psychosocial support. However, evidence is limited for whether existing interventions for this adolescent group reduce social or appearance-related distress. We therefore conducted a parallel-group, randomised control trial to evaluate the effectiveness of Young Person’s Face IT, a self-guided web-based psychosocial intervention developed for adolescents with a visible difference who experience distress. Adolescents (N = 189, aged 11–18) from two countries (Norway and the Netherlands), were randomly allocated to an intervention group or care as usual (CAU). Outcomes were body esteem, social anxiety, perceived stigmatisation, and life disengagement. Compared with CAU, participants who completed Young Person’s Face IT showed reductions in social anxiety symptoms ( = 0.06). No significant improvements were found for the other outcomes. This study endorses web-based psychosocial support in reducing social anxiety in adolescents distressed by a visible difference. Future studies are needed to confirm the effectiveness of Young Person’s Face IT and to explore potential long-term effects.

  The purpose of the paper was to examine Norwegians’ incorporation of seven varied sexual acts. Data were obtained from a questionnaire survey of a probability-based web sample of 2,181 men and 1,967 women aged 18–89 years. Among seven acts of sexual variety, the most common sexual experiences were trying to watch pornography with a partner, engaging in sex in unusual places, and using sex toys. Older age was negatively associated with all acts of sexual variety. Regarding more unorthodox acts of sexual variety, heterosexual men’s sexual preferences involved having and desiring group sex, whereas heterosexual women’s sexual experiences and desires involved having sex in unusual places. Lesbian, gay, bisexual (LGB) individuals generally showed greater curiosity or experience of having group sex and engaging in BDSM (bondage, discipline, dominance and submission, and sadomasochism) activities than heterosexual adults. However, while LGB men had a high preference for group sex activities, LGB women had more positive attitudes towards BDSM activity. Individuals appear to accumulate more acts of sexual variety over time, thus making the incorporation of sexual variety a function of age. This study supports the idea that sexual variety has expanded among those born from 1960 onwards.

  Purpose: To study different subgroups of Norwegians’ frequency of sexual intercourse and the activities that Norwegians engage in during intercourse. Methods: Data were collected from a questionnaire survey of a representative web sample of 4,160 Norwegians aged 18 to 89 years. The response rate was 35%. Results: The majority of men (65%) and women (61%) reported sexual intercourse activity during the past month, and it was most common to report such activity 2 or 3 times per month. Partnered participants most often reported having intercourse weekly. The intercourse frequency of 2 to 3 times per week declined from 35% in participants aged 18 to 29 years to 8% in participants 60 years and older. The most common heterosexual activities reported were vaginal sex, stimulated genitals with the hands or mouth, use of sex toys, and anal sex. Younger and middle-aged Lesbian, Gay, Bisexual, Transgender/Transsexual, Intersex, Asexual [LGBTIA] men most often reported activities such as mutual masturbation, oral sex, and anal sex. Younger and middle-aged LGBTIA women most frequently reported mutual masturbation, vaginal sex, and oral sex. Conclusion: There seems to be a generational shift in types of activities in participants 59 years or younger, and those 60 years and above.

  Severe obesity has been associated with reduced performance on tests of verbal memory in bariatric surgery candidates. There is also some evidence that bariatric surgery leads to improved verbal memory, yet these findings need further elucidation. Little is known regarding postoperative memory changes in the visual domain and how patients subjectively experience their everyday memory after surgery. The aim of the current study was to repeat and extend prior findings on postoperative memory by investigating visual, verbal, and self-reported everyday memory following surgery, and to examine whether weight loss and somatic comorbidity predict memory performance. The study was a prospective, observational study in which participants (n = 48) underwent cognitive testing at baseline, 1 and 2 years after bariatric surgery. Repeated measures analyses of variance revealed significantly poorer visual and verbal memory performance at the 1-year follow-up, with performance subsequently returning to baseline levels after 2 years. Verbal learning and self-reported everyday memory did not show significant postoperative changes. Memory performance at 1 year was not significantly predicted by weight loss, changes in C-reactive protein levels or postoperative somatic comorbidity (Type 2 diabetes, sleep apnea, and hypertension). The study demonstrated poorer visual and verbal memory performance at 1-year follow-up that returned to baseline levels after 2 years. These findings are in contrast to most previous studies and require further replication, however, the results indicate that postoperative memory improvements following bariatric surgery are not universal. Findings suggest that treatment providers should also be aware of patients potentially having poorer memory at 1 year following surgery.

  The Breast Size Satisfaction Survey (BSSS) was established to assess women’s breast size dissatisfaction and breasted experiences from a cross-national perspective. A total of 18,541 women were recruited from 61 research sites across 40 nations and completed measures of current-ideal breast size discrepancy, as well as measures of theorised antecedents (personality, Western and local media exposure, and proxies of socioeconomic status) and outcomes (weight and appearance dissatisfaction, breast awareness, and psychological well-being). In the total dataset, 47.5 % of women wanted larger breasts than they currently had, 23.2 % wanted smaller breasts, and 29.3 % were satisfied with their current breast size. There were significant cross-national differences in mean ideal breast size and absolute breast size dissatisfaction, but effect sizes were small (η2 = .02–.03). The results of multilevel modelling showed that greater Neuroticism, lower Conscientiousness, lower Western media exposure, greater local media exposure, lower financial security, and younger age were associated with greater breast size dissatisfaction across nations. In addition, greater absolute breast size dissatisfaction was associated with greater weight and appearance dissatisfaction, poorer breast awareness, and poorer psychological well-being across nations. These results indicate that breast size dissatisfaction is a global public health concern linked to women’s psychological and physical well-being.

  Body image issues can affect all domains of sexual functioning. The aim of this study was to examine how, in a sociocultural context where physical and sexual attractiveness is equated with young and slim body ideals, appearance dissatisfaction and importance are related to sexual satisfaction in older adults in four European countries. A cross-sectional survey with probability samples of the population aged 60–75 years was used. Only respondents with a partner were included in this paper, and the countries included Norway (n = 957), Denmark (n = 846), Belgium (n = 612), and Portugal (n = 367). Sexual satisfaction, appearance dissatisfaction, and importance were assessed, and frequency of intercourse/kissing and cuddling, relationship satisfaction, age, and body mass index were all used as control variables. Belgian men scored significantly lower on sexual satisfaction, while there was no difference in sexual satisfaction in women. Appearance dissatisfaction was lower in Scandinavian women and men, and in Belgian men, and appearance salience was lower in Norwegian men and women, and in Portuguese women. Linear regression analysis revealed that, adjusting for confounders, appearance dissatisfaction was significantly related to sexual satisfaction in Scandinavian women and men, as well as in Belgian men. Compared to research on younger adults, appearance evaluation appeared to play an equally important role in sexual satisfaction in older adults in our study. The variation in appearance dissatisfaction in older adults across European countries is a novel finding that needs to be examined further.

  The aim of the study was to explore attitudes towards sexuality and sexual behavior in older adults in Norway, Denmark, Belgium, and Portugal. A cross-sectional survey with representative samples of the population aged 60–75 years recruited through phone registers in Norway (676 men and 594 women), Denmark (530 men and 515 women), Belgium (318 men and 672 women), and Portugal (236 men and 273 women) was conducted. The data collection was carried out using an anonymous postal questionnaire. Four dimensions of attitudes towards sexuality were identified: ‘sex for love’, ‘sexual pressure in society’, ‘sex for well-being’, and ‘sexual changes and ageing’. Discriminant analyses identified three discriminant attitude functions: sex for well-being, sexual changes due to ageing, and sex for love. Portuguese men had positive attitudes towards sex as good for well-being in older adults but believed ageing was an obstacle to being sexual at this stage of life. Portuguese women believed sex was good for well-being and did not consider ageing an obstacle to sexual enjoyment. Norwegian men and Danish women believed changes in sexuality due to ageing were no obstacle to being sexual but did not believe that sex was good for well-being. The attitudes of Belgian and Danish men were largely inclined in the direction that sex is not particularly important for elderly people and that changes in sexuality occur due to the ageing process. Men and women were committed to the attitude of sex for love, although this was observed most in Belgian participants and least in Danish men. Positive attitudes towards sex for wellbeing and towards ageing and sexual changes correlated with less change in sexual interest and sexual enjoyment, and with increased frequency of intercourse and masturbation. To tailor successful sexual health interventions, attitudes of sexuality in older people should be addressed.

  What is the prevalence of using the Internet for love and sexual activities among older adults across Europe, and what predicts such use? Data were collected in probability samples among populations aged 60–75 years in Norway (N = 1271), Denmark (N = 1045), Belgium (N = 991), and Portugal (N = 509) using postal questionnaires. A total of 36% of men and 15% of women reported having used the Internet for sex and love purposes, most often to watch pornography. The use of the Internet for various love and sex purposes was higher in participants who had a partner, who had masturbation activity and who were satisfied with their current level of sexual activity. Multivariate logistic regression analyses showed that use of the Internet to find committed partners, watch pornography, buy sex products or seek information or advice was lower in Portuguese men than men in Norway, Denmark, and Belgium. Tailored websites to promote both sexuality and how to preserve a committed relationship are likely to prove important for the aging population.

  The aim of the current study was to explore whether developmental trajectories of body satisfaction from adolescence to young adulthood predicted measures of sexual satisfaction in young adulthood, even when controlling for important covariates such as gender, weight development, relationship status, mental health, and frequency of sexual intercourse and masturbation. Data were collected from a population-based prospective cohort of Norwegian adolescents (n = 2,587) over a period of 13 years in four waves (1992, 1994, 1999, and 2005; mean age = 14.9 in 1992, 57.3% women). Latent growth curves were estimated for body satisfaction and Body Mass Index (BMI). Men reported higher sexual satisfaction, sexual activity, baseline body satisfaction, and BMI than women. The developmental trajectories revealed a slight increase in body satisfaction and BMI from adolescence to young adulthood in both genders. Moreover, structural equation models showed that baseline body satisfaction in both genders predicted sexual satisfaction as a young adult, independent of relationship status and frequency of sexual activity. Neither the development of BMI nor of body satisfaction predicted sexual satisfaction. The results elucidate the vital role of body satisfaction in sexual satisfaction in adults and the importance of addressing body dissatisfaction in childhood.

  Background The experience of symptoms after bariatric surgery such as pain, dumping, and fatigue, may affect behavior, quality of life, and the need for health care consultations. Attention to and interpretation of symptoms are influenced by psychological and contextual factors. Prospective studies of psychological factors predicting physical symptom perception after bariatric surgery are scarce. Objectives To explore the association of preoperative negative affect, history of traumatic sexual and violent events, with frequency and intensity of self-reported symptoms, one year after Roux-en-Y gastric bypass (RYGB). Setting University hospital Methods Questionnaire data were collected before and one year after RYGB from 230 patients. Negative affect and stressful negative life events were measured preoperatively. The participants reported the number and degree of impact of various physical symptoms postoperatively. Results The most common symptoms reported to have a high impact on behavior were fatigue (32.8%), and dumping (28.4%). Reporting more symptoms was associated with preoperative anxiety (r = .22, p = .001), and number of stressful life events (r = .21, p = .002). Participants with a probable preoperative anxiety disorder reported higher impact of fatigue, pain, dumping, and diarrhea after surgery, while those with a probable mood disorder and history of traumatic events reported higher impact of dumping. Conclusion Preoperative anxiety symptoms and stressful experiences were associated with higher perceived impact of symptoms, such as dumping, fatigue, and pain after RYGB. Evaluation of psychological characteristics associated with symptom perception may be relevant during handling of symptoms not responsive to other treatment measures.

  Background: Most patients do not meet the recommended level of physical activity after bariatric surgery, and psychological factors underlying postoperative physical activity remain poorly understood. This study aimed at identifying self-regulatory predictors of physical activity after bariatric surgery. Methods: Questionnaire data including self-regulation variables and the short-version of the International Physical Activity Questionnaire were obtained in a prospective cohort of 230 patients 1 year after Roux-en-Y gastric bypass. The study sample consisted of participants consenting to wear an ActiGraph GT3X+ accelerometer for seven consecutive days, 18–24 months after surgery (n = 120). Results: A total of 112 participants with complete self-report data provided valid accelerometer data. Mean age was 46.8 years (SD = 9.3), and 81.3% was women. Preoperative and postoperative BMI was 44.8 ± 5.5 and 30.6 ± 5.0 kg/m2, respectively. Total weight loss was 28.9% (SD = 7.5). By objective measures, 17.9% of the participants met the recommended level of moderate-to-vigorous-intensity of physical activity of ≥150 min/week, whereas 80.2% met the recommended level according to self-reported measures. Being single, higher education level, and greater self-regulation predicted objective physical activity in multivariate regression analysis. Greater self-regulation also predicted self-reported physical activity. Weight loss 1 year after surgery was not associated with self-reported or objectively measured physical activity. Conclusions: Despite large differences between accelerometer-based and subjective estimates of physical activity, the associations of self-regulatory factors and weight loss with postoperative physical activity did not vary depending on mode of measurement. Self-regulation predicted both objective and self-reported physical activity. Targeting patients’ self-regulatory ability may enhance physical activity after gastric bypass.

  During adolescence, romantic relationships are a key developmental milestone. Coupled with the increasing salience of appearance and social acceptance, adolescents with an appearance-altering condition may feel particularly vulnerable when it comes to romantic relationships. This study aimed to explore the prevalence of romantic experiences among adolescents with a cleft lip and/or palate (CL/P), and to investigate how these experiences could be related to depressive symptoms and global self-worth. The study included 661 Norwegian adolescents with CL/P, who were compared to a large national sample. The prevalence of romantic relationships was lower among adolescents with CL/P compared to the reference group, although the overall impact on depressive symptoms and global self-worth appeared to be low. This study is one of few to explore the impact of a congenital visible condition on experiences of romantic relationships and provides preliminary insight into a significant, yet complex topic.

  Background Little is known about the psychological prerequisites for weight loss maintenance after bariatric surgery. A first step in investigating whether existing knowledge of conservative weight loss treatment is applicable for lifestyle interventions postoperatively is to compare specific psychological characteristics at baseline. The aim of this study was to compare patients scheduled for bariatric surgery with patients receiving conservative treatment for morbid obesity on measures of behavioral and psychosocial characteristics considered predictors of their adoption of and adherence to long-term lifestyle recommendations. Methods Baseline clinical and questionnaire data from the prospective “Oslo Bariatric Surgery Study” were used to examine potential differences between bariatric surgery patients (n = 301) and patients receiving conservative weight loss treatment (n = 261). Results The surgical group was characterized by their younger age (43.8 vs. 46.2 years, p <0.01), higher percentage of women (79.1 vs. 70.1 %, p <0.05), and higher Body Mass Index (BMI; 45.0 vs. 41.9 kg/m2, p <0.001). A multiple logistic regression analysis, adjusting for group differences in BMI, gender, and age, showed that the surgical group had higher self-efficacy (Odds ratio; OR = 3.44, 95 % Confidence interval; CI 1.65, 7.14), more positive outcome expectations (OR = 1.53, 95 % CI 1.23, 1.89), and plans that were more explicit for changing their eating behaviors (OR = 1.80, 95 % CI 1.06, 1.93). The surgical patients were also less ready to change physical activity levels (OR = 0.59, 95 % CI 0.48, 0.73), had tried more types of unhealthy weight loss methods in the past (OR = 1.16, 95 % CI 1.01, 1.33), drank soda more frequently (OR = 1.24, 95 % CI 1.02, 1.50), had fewer binge eating episodes (OR = 0.38, 95 % CI 0.20, 0.71), and had more depressive symptoms (OR = 1.19, 95 % CI 1.09, 1.29). Conclusions Patients opting for bariatric surgery had more positive expectations of the treatment outcomes and stronger beliefs in their ability to achieve these outcomes. Those starting conservative treatment had stronger beliefs in readiness to change physical activity levels. Future studies should explore the effect of interventions for bariatric surgery patients, promoting postoperative physical activity and stress realistic outcome expectations. The potential effects of incorporating this knowledge in intervention strategies remain to be explored.

  ackground: Weight loss and weight loss maintenance vary considerably between patients after bariatric surgery. Postoperative weight gain has partially been explained by lack of adherence to postoperative dietary and physical activity recommendations. However, little is known about factors related to postoperative adherence. Objectives: The aim of this study was to examine psychological, behavioral, and demographic predictors of adherence to behavior recommendations and weight loss 1 year after bariatric surgery. Setting: Oslo University Hospital. Methods: In a prospective cohort study, 230 patients who underwent Roux-en-Y gastric bypass were recruited from Oslo University hospital from 2011 to 2013. They completed a comprehensive questionnaire before and 1 year after surgery. Weight was measured preoperatively, on the day of surgery, and 1-year postoperatively. Results: Mean body mass index was 44.9 kg/m 2 (standard deviation [SD] ¼ 6.0) preoperatively and 30.6 kg/m 2 (SD ¼ 5.2) 1 year after surgery. Patients lost on average 29.2 % (SD ¼ 8.2) of their initial weight. Predictors of dietary adherence were years with dieting experience, readiness to limit food intake, and night eating tendency. Preoperative physical activity and planning predicted postoperative physical activity whereas predictors of weight loss were higher frequency of snacking preoperatively, greater past weight loss, and lower age. Conclusion: Several preoperative psychological predictors were related to postoperative adherence to dietary and physical activity recommendations but were not associated with weight loss. Inter- ventions targeting psychological factors facilitating behavior change during the initial postoperative phase are recommended as this might improve long-term outcomes.

  Abstract Objective: To study the relationship between age, gender, body mass index (BMI), body image, and perceived intimacy with partner and sexual satisfaction in young Norwegian adults. Methods: A questionnaire survey was completed online by 27.2 % (n = 568) of a representative national web sample of 2,090 persons aged 18–29 years. Results: Women were more dissatisfied with their body than men and BMI increased with age. A negative body image correlated with BMI, particularly among women. There was no gender difference in reported sexual satisfaction and perceived intimacy with partner. The most important direct path leading to increased sexual satisfaction was from perceived intimacy with partner, followed by body image and age. By influencing body image, BMI and gender influenced sexual satisfaction indirectly. Being male increased the likelihood of having a positive body image, which in turn increased the likelihood of reporting being sexually satisfied. Additionally, a lower BMI increased the likelihood of being satisfied with one’s body, which in turn increased sexual satisfaction. Conclusion: Body image is clearly related to sexual satisfaction, particularly in women. However, body image is not associated with the perception of intimacy with one’s partner, which is the most important factor for feeling sexually satisfied.

  In young people, interactions with horses may contribute to the development of social skills and self-efficacy. Our aim was to identify relationships between psychological variables and young people’s experience of activities with horses. Participants in this study were 13–15-year-old adolescents (n = 25), given a 4-month intervention consisting of weekly sessions of stable work and horse-back riding. We investigated the relationship between psychological variables from survey data with video-recorded behavioral observations during tasks and contact with horses. From the behavioral data, we calculated the frequency per hour of “trying again” when met with a challenge, as a measure of participants’ persistence in horse-related tasks. The number of times per hour that that participant initiated contact with the horse was used as a measure of frequency of physical contact (petting). We examined correlations between the change from early to late stages of the intervention in trying again during horse-related tasks and for physical contact and three psychological variables measured prior to the intervention: perceived social support, self-esteem, and general self-efficacy. We detected an association between lower pretest levels of perceived social support and general self-efficacy, and an increase during the intervention in persistence of trying again when met with challenges during tasks with the horse. In a linear regression analysis, controlling for initial levels of persistence during horse-related tasks, self-esteem, and self-efficacy, social support was the only unique predictor of an increase in persistence during the intervention. No association was found between the psychological variables and change in frequency of petting the horse. The results indicate that adolescents with lower levels of perceived social support at the start of the intervention showed greater increases in their persistence in trying again after being met with challenges during horse-related tasks. Since persistence is a central aspect in the development of mastery of tasks, the possible positive social impact of the horse/stable environment should be given more attention in future intervention research.

  The purpose of this study was to investigate the hypothesis that the effect of body dissatisfaction on disordered eating behavior is mediated through self-esteem and depression. If the effect of body dissatisfaction on disordered eating can be explained by self-esteem and depression, treatment may benefit from focusing more on self-esteem and depression than body dissatisfaction. We also hypothesized body image importance to be associatedwith lower self-esteem, stronger symptomsof depression, andmore disordered eating. The results showed that the effect of body dissatisfaction on disorder eating was completely mediated, whereas the effect of body image importance was partly mediated. Both self-esteem and depression were significant mediators. Body image importance and self-esteem had a direct effect on restrained eating and compensatory behavior. Depression had a direct effect on binge eating. This effectwas significantly stronger amongwomen. Depression also had a direct effect on restrained eating. This effect was positive among women, but negative among men. The results support emotion regulation and cognitive behavioral theories of eating disorders, indicating that self-esteemand depression are the most proximal factors, whereas the effect of body dissatisfaction is indirect. The results point out the importance of distinguishing between different symptoms of bulimia. Depression may cause binge eating, but compensatory behavior depends on self-esteemand body image importance. The results suggest that women may turn to both binge eating and restrained eating to escape awareness of negative emotions, whereas men focus on eating to a lesser extent than women. Existing treatment focuses on eating behavior first and mechanisms such as self-esteem and depression second. The results from this study suggest that an earlier focus on self-esteem and depression may be warranted in the treatment of disordered eating.

  Objective:  Explore psychological functioning in adolescents with a cleft at age 16 from a broad perspective, including cognitive, emotional, behavioral, appearance-related, and psychosocial adjustment. High-risk groups were identified within each area of adjustment to investigate whether vulnerable adolescents were found across domains or whether risk was limited to specific areas of adjustment. Methods:  Cross-sectional data based on psychological assessments at age 16 (N = 857). The effect of gender, cleft visibility, and the presence of an additional condition were investigated on all outcome variables. Results were compared with large national samples. Measures:  Hopkins Symptom Checklist, Harter Self-Perception Scale for Adolescents, Child Experience Questionnaire, and Satisfaction With Appearance scale. Results:  The main factor influencing psychological adjustment across domains was gender, with girls in general reporting more psychological problems, as seen in reference groups. The presence of an additional condition also negatively affected some of the measures. No support was found for cleft visibility as a risk factor except for dissatisfaction with appearance. Correlation analyses of risk groups seem to point to an association between social and emotional risk and between social risk and dissatisfaction with appearance. Associations between other domains were found to be weak. Conclusions:  The results point to areas of both risk and strength in adolescents born with a cleft lip and/or palate. Future research should investigate how protective factors could counteract potential risk in adolescents with a cleft.

  This study explores how body ideals are discussed among adolescent boys and girls in 5 mixed-gender focus groups (n = 37). The ways in which boys and girls talk about bodies differed clearly within the focus group conversations as well as in the everyday situations described in the interviews. The boys were more concrete in their description of ideal bodies in the focus groups but reported less engagement in everyday body talk. The study demonstrates that self-derogating “fat talk” is normative in the meaning “easy to fall into” but not normative in the meaning “approved of”: Fat talk is more or less required in some situations but not really appreciated. Both girls and boys agreed on this description of fat talk among girls. They also agreed that fat talk rarely occurred among boys. It was a general consensus that body issues are more sensitive and problematic for girls than for boys.

  This study examined the associations among the frequency of viewing Internet pornography, beliefs about how realistically pornography portrays sex, self-perceived effects of one’s pornography use, genital appearance satisfaction, and sexual self-esteem in young adults. Online data were collected from four convenience samples of university students from Norway and Sweden, members of a queer youth organization, and readers of an erotic magazine. Because of cultural similarities and the comparable magnitude and patterns of the bivariate correlations among the samples on the study variables, they were pooled into a single sample (N = 1,274). The majority of men (81.1%) and a minority of women (18.1%) reported at least weekly use of Internet pornography on their personal computers, whereas using a mobile phone or tablet was less common. Most of the participants had sought mainstream pornographic content. Those with a stronger belief in pornographic realism were more likely to perceive the effect of pornography use positively. A hypothesized relationship between self-perceived positive effects of pornography use and a higher level of sexual self-esteem was found for men but not for women. This result was partially due to higher satisfaction with genital appearance among the men who mainly watched mainstream pornography. Genital appearance satisfaction was linked to higher sexual self-esteem for women, but it was not related to the self-perceived effect of pornography use. The results indicate that pornography may expand personal sexual scripts for both men and women, and may have a positive, although modest, influence on the sexual self-esteem of young male adults.

  The study investigates how body ideals are discussed and conceptualized among groups of Norwegian youth. Altogether 48 girls and 15 boys, most aged 17 years, took part in nine focus groups, in order to study subcultural body ideals. Major differences were found between east-end and west-end boys (representing socioeconomic differences), where the former were more concerned about being big. Even though the ideals were more or less the same across the groups, the ways of addressing, conceptualizing and discussing body ideals clearly differed between the groups. The analyses reveal that body talk within peer groups seems to contribute to define adequate levels of effort that should be put into reaching the dominating body ideal.

  Earlier studies have indicated that learning to handle a horse through tasks and activities can lead to a feeling of mastery which may have an impact on self-efficacy. The aim of this study was to examine how adolescents conducted horse-related tasks presented to them in an intervention in a farm environment, and whether there was a change during the intervention in persistence on tasks with the horse. Furthermore, we wanted to examine the behavior of the adolescents towards the horse and the response from the horse. Each participant was given an intervention once a week for approximately 16 weeks consisting of tasks with the horse, riding, grooming, and stable work. The sample presented in this study consisted of 29 participants who were successfully video-recorded in the beginning and at the end of the intervention. Petting the horse was the most frequent way of initiating contact with the horse, and the distributions of contact behaviors were the same at both time spots. The response of the horse was mainly neutral or positive. When participants did not succeed at their first attempt when trying to solve a horse-related task or an exercise during riding, their subsequent behavior was recorded as either trying again or not trying again. Early in the intervention, these two options were chosen with about the same frequency, while at the end of the intervention trying again was chosen significantly more often than not trying again. This was operationalized as an increase in persistence when having difficulties in solving tasks with the horse. The increased persistence late in the intervention in retrying tasks may indicate that the adolescents developed a feeling of mastery, which is an important factor in development of self-efficacy.

  Few studies have tested potential explanatory mechanisms for the high stability of extraversion. In this study, the relationship between extraversion, appearance evaluation, and cosmetic surgery was investigated to examine such mechanisms. The ‘‘Big Five” personality traits were assessed in 155 female cosmetic surgery patients prior to and 6 months after surgery, as well as from a representative sample of 907 women. Patients showed higher extraversion scores prior to surgery than were found in the representative sample; further, extraversion scores increased after surgery, while the increase diminished when controlled for appearance evaluation. The results are in accordance with a transactional model, whereby extraverts engage in actions that reinforce extravert tendencies, which may account for the high stability of extraversion.

  Background: This study aims to investigate whether cosmetic surgery has an effect on an individual’s body image, general self-esteem, and psychological problems. Further tests were conducted to assess whether the extent of psychological problems before surgery influenced improvements in postoperative psychological outcomes. Methods: Questionnaire data from 155 female cosmetic surgery patients from a plastic surgery clinic were obtained before and approximately 6 months after surgery. The questionnaire consisted of measures on body image, self-esteem, and psychological problems. Pre- and postoperative values were compared. Pre- and postoperative measures were also compared with the data compiled from a representative sample of 838 Norwegian women, aged 22e55, with no cosmetic surgery experience. Results: No differences in psychological problems between the presurgery patient and comparison sampleswere found,whereas differences in body image and self-esteembetween the sample groups were reported in an earlier publication. Analyses further revealed an improvement in body image (satisfactionwith ownappearance) after surgery. A significant but rather small effect on self-esteem was also found, whereas the level of psychological problems did not change after surgery. Postoperative measures of appearance satisfaction, self-esteem, and psychological problems did not differ from values derived from thecomparison sample. Finally, fewpsychological problems before surgery predicted a greater improvement in appearance satisfaction and self-esteem after surgery. Conclusions: The study provides evidence of improvement in satisfaction with own appearance after cosmetic surgery, a variable that is thought to play a central role in understanding the psychology of cosmetic surgery patients. The study also points to the factors that surgeons should be aware of, particularly the role of psychological problems, which could inhibit the positive effects of cosmetic surgery.

An online psychological intervention for adolescents with a visible difference: Acceptability, feasibility and effectiveness of YP Face IT. Show summary

  Background/Objective: Adolescents with a visible difference can experience challenging social situations, (e.g., people staring or making unwanted comments) and are at risk for mental health problems. Interventions for adolescents with a visible difference experiencing appearance-related distress are scarce and lack an evidence-base. Therefore, YP Face IT was developed. This psychosocial eHealth intervention combines social skills training and cognitive behavioural therapy to help adolescents cope with challenging social situations and difficult thoughts. Method: To assess acceptability and feasibility 15 Dutch adolescents aged 12-17 completed YP Face IT and participated in in-depth interviews. Responses were analysed using thematic analysis. To assess effectiveness 189 Dutch and Norwegian adolescents participated in a Randomised Controlled Trial and were randomly allocated to YP Face IT or Care As Usual (CAU). Outcomes were body esteem, social anxiety, perceived stigmatisation, and life disengagement. Outcomes were measured at baseline and direct follow-up. Results: Acceptability and feasibility: Most adolescents appreciated the intervention and all would recommend it to other adolescents with a visible difference experiencing appearance-related distress. Effectiveness: Compared to CAU, participants who completed YP Face IT showed reductions in social anxiety. No significant results were found for the other outcomes. Conclusions: Both studies show that YP Face IT is acceptable, feasible and effective for adolescents with a visible difference. Dutch adolescents endorsed YP Face IT and its components. International results show that YP Face IT reduces social anxiety. Future studies are needed to confirm the effectiveness of YP Face IT and to explore potential long-term effects.
