  The benefit of universal access to Early Childhood Education and Care (ECEC) for children's development can depend on the ECEC quality and children's early childhood risks. This study utilised data from the Norwegian Mother, Father and Child Cohort Study (MoBa; N = 7355, 50.2% boys) to investigate the relative contribution of children's early childhood risk accumulated up to three years of age and five separate dimensions of ECEC quality on children's mental health (externalising and internalising problems) at five years of age rated by mothers and teachers. Results from the hierarchical regression models indicated that lower ECEC quality added to, and higher ECEC quality counteracted, the risk of mental health problems. Relationship quality was the strongest contributor. Total ECEC quality and relationship quality interacted significantly with early childhood risk, indicating that higher ECEC quality protected against, while lower ECEC quality exacerbated, the detrimental effects of early childhood risk on mental health problems.

  In this study, we explored how free play and scaffolding practices in Early Childhood Education and Care (ECEC) related to children’sexternalising problems both in ECEC and later in school.Furthermore, we aimed to reduce the knowledge gap of whether these relations depended on children’s differences in emotional temperament. We used structural equation modelling to analysedata from 7421 children from the Norwegian Mother, Father an dChild Cohort Study. Results indicated that more free playassociated with less externalising problems in ECEC for children ingeneral. For children with higher emotionality, more free playrelated to increased externalising problems in school. Scaffoldingin ECEC was not associated with externalising problems, butmoderated the longitudinal association of free play for children with higher emotionality. All children benefited from free play in ECEC for their concurrent mental health. However, for childrenwith higher emotionality, more free play in ECEC might be a riskfactor for reduced mental health in school, where there is lessfree play than in ECEC. More scaffolding in combination with freeplay in ECEC can reduce this risk. Further research should addressthe content of play and scaffolding practices in more detail.

  Objectives To compare the socioeconomic status (SES) and case-mix among day surgical patients treated at private for-profit hospitals (PFPs) and non-profit hospitals (NPs) in Norway, and to explore whether the use of PFPs in a universal health system has compromised the principle of equal access regardless of SES. Design A retrospective, exploratory study comparing hospital types using the Norwegian Patient Register linked with socioeconomic data from Statistics Norway by utilising Norwegian citizens’ personal identification numbers. Setting The Norwegian healthcare system. Population All publicly-financed patients in five Norwegian metropolitan areas having day surgery for meniscus (34 100 patients), carpal tunnel syndrome (15 010), benign breast hypertrophy (6 297), or hallux valgus (2 135) from 2009–2014. Primary outcome measure Having surgery at a PFP or NP. Results Across four unique procedures, the adjusted odds ratios (aORs) for using PFPs were generally lower for the lowest educational level (0.77–0.87) and the lowest income level (0.68–0.89), though aORs were not always significant. Likewise, comorbidity and previous hospitalisation had lower aORs (0.62-0.95; 0.44-0.97, respectively) for having surgery at PFPs across procedures, though again aORs were not always significant. No clear patterns emerged with respect to age, gender, or higher levels of income and education. Conclusions The evidence from our study of four procedures suggests that equal access to PFPs compared to NPs for those patients at the lowest education and income levels may be compromised, though further investigations are needed to generalise these findings across more procedures and probe causal mechanisms and appropriate policy remedies. The finding that comorbidity and previous hospitalisation had lower odds of treatment at PFPs indicates that NPs play an essential role for more complex patients, but raises questions about patient preference and cream skimming.

  I underkant av 500 000 personer har private helseforsikringer i Norge, de fleste gjennom arbeidsgiverfinansierte kollektive ordninger. Forsikringene skal primært gi raskere tilgang til spesialisthelsetjenester. Vi bruker data fra en spørreundersøkelse supplert med registerdata fra Brønnøysundregistrene og analyserer sannsynligheten for å ha privat helseforsikring. Vi finner at sannsynligheten for private helseforsikringer øker med antall ansatte og med andel menn i bedriften, men reduseres med sykefravær på næringsnivå. Arbeidsgivers avgjørelse om å kjøpe private helseforsikringer er påvirket av ansattes preferanser og arbeidsgivers oppfatning om at private helseforsikringer kan brukes som rekrutteringsstrategi. I gjennomsnitt er bedriftene fornøyd/veldig fornøyd med det medisinske tilbudet som gis gjennom private helseforsikringer.

  I Følge helse- og omsorgstjenesteloven av 2011 skal kommunene tilby heldøgns medisinsk akuttbehandling fra 1. januar 2016. Målet med tilbudet som er kalt kommunal øyeblikkelig hjelp døgnenheter (ØDH), er å redusere antall innleggelser ved sykehusene særlig for den eldre befolkningen. I notatet analyseres om etablering av ØDH-er faktisk har påvirket antall innleggelser ved sykehusene. Vi har hentet inn data om antall innleggelser fra Norske paientregister, data om demografiske variable og data om det kommunale tilbudet av tjeneste utover ØHD-ene fra Statistisk sentralbyrå og data om tidspunkt for etablering av ØHD-ene fra kommunene. Data er analysert som et panel med faste effekter for kommune. Konklusjonene er at innføring av ØDH-ene har hatt effekt, men også at effektene varierer betydelig med hvordan ØDH-ene er organisert. I gjennomsnitt finner vi effekter av innføring av ØDH-er på innleggelser for pasienter over 80 år på knapt (minus) 2%. Det ØDH-ene som er samlokalisert med legevekt og som har god legeberedskap som har effekter. ØDH-er som har annen organisering enn dette har i gjennomsnitt ingen effekt, men det er store variasjoner på kommunenivå.

  Using data from the Norwegian Mother, Father and Child Cohort Study (MoBa), as well as data collected from the children’s teachers in ECEC (at 5 years) and school (at 8 years), this thesis seeks to expand the knowledge on the environmental factors that shape child development. Specifically, the thesis focuses on Early Childhood Education and Care (ECEC) as an important environmental context for child development. Children from less advantageous socioeconomic backgrounds are argued to benefit most from attending ECEC. Nevertheless, the benefits of ECEC for child development are critically dependent on quality. In the first paper, we investigate potential socioeconomic inequalities regarding access to quality in ECEC, in a context where universal policies are expected to ensure equal access for all children. However, limited evidence exists on whether universal policies have succeeded in achieving this goal. We found some indications of socioeconomic inequalities in the access to quality in ECEC, suggesting selection as one of the potential mechanisms. The children of higher-educated parents appeared to access a higher structural quality that together with the parental SES predicted a better relationship quality with their teachers. In the second paper, we examine some of the mechanisms between different aspects of quality, child functioning and well-being in ECEC. The results suggest that structural quality aspects influence children mainly indirectly via its impact on the relationship quality. Further, we employed a sibling design to address omitted variable bias in the associations between the student-teacher relationship and child outcomes. The associations between the relationship quality (in terms of closeness) and child functioning were relatively strong, even after accounting for relevant child characteristics and unobserved stable family factors. In the third paper, we extend our investigation to school age children, linking their relational experiences with teachers in ECEC and school to their behavioral outcomes outside the educational context (as observed by their mothers). Specifically, we study the associations between student-teacher closeness and conflict and children’s internalizing and externalizing behavior. To strengthen the internal validity of the evidence we used conditional within-person and within-family models (individual and sibling fixed-effects). The overall results provided support for the importance of the student-teacher relationship for child behavioral functioning beyond the ECEC and school context.
