The centrality of food in Norwegian adolescents’ life; a photo elicitation study among Norwegian youth
The purpose of the study was to explore how adolescents from a high school in Viken county define and interact with food systems in their immediate environments to understand if and how health and sustainability affect their food choices. A qualitative case study design and a participatory approach were employed. Data were collected through photo elicitation combined with group interviews. Pictures were analyzed in collaboration with participants…
Democratising participatory health promotion
Public policy aimed at preventing undesired phenomena has increasingly sought to engage representatives of the target population. Little is known, however, about how power dynamics function to shape the processes and outcomes of risk governance engagement interventions. In order to study the ways in which, and the extent to which, power differentials can be reduced in participatory health promotion initiatives, we develop a conceptual framework s…
Mediators and moderators of the effects of a school-based intervention on adolescents’ fruit and vegetable consumption
Objective: To examine whether targeted determinants mediated the effects of the HEalth In Adolescents (HEIA) intervention on fruit and vegetable (FV) consumption and explore if these mediating effects were moderated by sex, parental education or weight status. Design: Cluster-randomised controlled trial. Setting: The HEIA study (2007–2009) was a Norwegian 20-month multi-component school-based intervention to promote healthy weight development. FV…
Negotiating policy ideas
Between 2019 and 2021, 199 adolescents collaborated with adults in 15 participatory action research projects, called Youth Alliances, to contribute to system-directed obesity prevention in five EU countries. We investigated if and how these Youth Alliances included diverse youth, enhanced engagement, generated policy proposals and changed problem perception. We assessed the Youth Alliances from a micro-sociological perspective of negotiated order…
Effect of Ending the Nationwide Free School Fruit Scheme on the Intake of Fruits, Vegetables, and Unhealthy Snacks in Norwegian School Children Aged 10–12 Years
The Norwegian authorities started a nationwide free school fruit program in 2007, implemented in all secondary schools (grades 8-10) and combined schools (grades 1-10) in Norway. The program ended in 2014. This study evaluates the effect of ending the nationwide free school fruit program on the consumption of fruit, vegetables, and unhealthy snacks among Norwegian sixth and seventh graders.

Cross-national variation in the association between family structure and overweight and obesity
The study indicates that living in a one-parent family, as well as living together with grandparents, are associated with overweight and obesity among adolescents, particularly in the Nordic European region. Existing welfare policies may be insufficient to eliminate inequalities related to family structure differences
Adolescents’ Perspectives on the Drivers of Obesity Using a Group Model Building Approach
Overweight and obesity increase the risk of a range of poor physiological and psychosocial health outcomes. Previous work with well-defined cohorts has explored the determinants of obesity and employed various methods and measures; however, less is known on the broader societal drivers, beyond individual-level influences, using a systems framework with adolescents. The aim of this study was to explore the drivers of obesity from adolescents' pers…

Setting Intakes of fruits, vegetables and snacks were assessed by frequency and intakes of sug…
Correlates of weight status among Norwegian 11-year-olds
The present study showed a social gradient in weight status in 11-year-olds. Both breakfast consumption and moderate to vigorous physical activity were inversely associated with weight status. No associations were found between intake of sugar-sweetened beverages and snacks, playing computer games and weight status. Watching TV was positively associated with weight status for boys but not for girls. Interventions are needed to gain more insight i…
Changes in beverage consumption in Norwegian children from 2001 to 2008

Design Within the Fruits and Vegetables Make the Marks (FVMM) project, 6th and 7th grade pupils filled in a questionnaire about frequency of beverage intake (times/week) in 2001 and 2008. Sett…
Determinants of fruit and vegetable consumption among children and adolescents
Large proportions of children do not fulfil the World Health Organization recommendation of eating at least 400 grams of fruit and vegetables (FV) per day. To promote an increased FV intake among children it is important to identify factors which influence their consumption. Both qualitative and quantitative studies are needed. Earlier reviews have analysed evidence from quantitative studies. The aim of this paper is to present a systematic revie…
Can any teacher teach sexuality and HIV/Aids? Perspectives of South African Life Orientation teachers
In this paper we explore the perceived desirable characteristics of South African Life Orientation teachers for teaching sexuality and HIV/AIDS. We also investigate the extent to which these characteristics can be understood as parts of a role script for teaching HIV/AIDS and sexuality. Data were collected from teachers who taught Grade Eight and Grade Nine students in South African public high schools. The teachers particularly emphasised the im…

Design Within the Fruits and Vegetables Make the Marks (FVMM) project, two cross-sectional st…
The effect of tailor-made information on vitamin D status of immigrant mothers in Norway
A high prevalence of vitamin D deficiency has been reported in non-Western immigrants in Norway. Our objective was to test whether written information about how to improve vitamin D status could improve the vitamin D status in immigrants mothers attending child health clinics. In this cluster randomized controlled trial in eight child health clinics in Oslo, mothers aged 18-43 years with Pakistani, Turkish, or Somali background were included when…
