Social Inequalities in Obesity Persist in the Nordic Region Despite Its Relative Affluence and Equity.

Social inequalities in overweight and obesity (OWOB) have persisted in the affluent and reputedly egalitarian Nordic countries. In this review we examine associations between socioeconomic position (SEP) and OWOB, and secular trends in such associations. Determinants and possible causes of the relations are discussed together with opportunities to cope with OWOB as a public health problem. The findings show a persisting inverse social gradient. An interaction between SEP and gender is noted for adults in Denmark, Finland and Iceland and for children in Sweden. There are overall tendencies for increased inequality, however no consistent trend for an increased social gradient in OWOB. Reasons that increased inequality does not unequivocally mirror in a steepened social gradient in obesity may include methodological questions as well as societal efforts to counteract obesity. Multi-level efforts are needed to prevent OWOB.

High school dropout and long-term sickness and disability in young adulthood: a prospective propensity score stratified cohort study (the Young-HUNT study).

BACKGROUND: High school dropout and long-term sickness absence/disability pension in young adulthood are strongly associated. We investigated whether common risk factors in adolescence may confound this association. METHODS: Data from 6612 school-attending adolescents (13-20 years old) participating in the Norwegian Young-HUNT1 Survey (1995-1997) was linked to long-term sickness absence or disability pension from age 24-29 years old, recorded in the Norwegian Labour and Welfare Organisation registers (1998-2008). We used logistic regression to estimate risk differences of sickness or disability for school dropouts versus completers, adjusting for health, health-related behaviours, psychosocial factors, school problems, and parental socioeconomic position. In addition, we stratified the regression models of sickness and disability following dropout across the quintiles of the propensity score for high school dropout. RESULTS: The crude absolute risk difference for long-term sickness or disability for a school dropout compared to a completer was 0.21% or 21% points (95% confidence interval (CI), 17 to 24). The adjusted risk difference was reduced to 15% points (95% CI, 12 to 19). Overall, high school dropout increased the risk for sickness or disability regardless of the risk factor level present for high school dropout. CONCLUSION: High school dropouts have a strongly increased risk for sickness and disability in young adulthood across all quintiles of the propensity score for dropout, i.e. independent of own health, family and socioeconomic factors in adolescence. These findings reveal the importance of early prevention of dropout where possible, combined with increased attention to labour market integration and targeted support for those who fail to complete school.

Medical benefits in young Norwegians and their parents, and the contribution of family health and socioeconomic status. The HUNT Study, Norway.

AIMS: Family and intergenerational perspectives might contribute to a better understanding of why young people in many European countries experience work impairment and end up being dependent on public benefits for life sustenance. The aim of this cohort study was to explore the relationship between the receipt of medical benefits in parents and their young adult offspring and the contributions of family health and family socioeconomic status. METHODS: Baseline information on the health of 7597 adolescents and their parents who participated in the HUNT Study 1995-1997 was linked to national registers to identify long-term receipt of medical benefits for parents (1992-1997) and adolescents as they entered adulthood (1998-2008). We used logistic regression to explore the association between parent and offspring receipt of medical benefits, adjusting for family health and socioeconomic status. RESULTS: Among adolescents, 13% received medical benefits from age 20-29. Adolescents whose parents had received medical benefits (26%) were more likely to receive such benefits themselves from age 20-29 compared with adolescents without benefit-receiving parents (age- and sex-adjusted odds ratio (OR) 2.16, 95 % confidence interval (CI) 1.86-2.49). Adjustment for family health reduced this estimate considerably (to OR 1.66, 95% CI 1.38-1.99), whereas adjustment for family socioeconomic status had less impact. CONCLUSIONS: Adolescents whose parents receive medical benefits enter adult working life with an elevated risk of health-related work exclusion. Family health vulnerability appears to be a key to understanding this association, suggesting that more attention to intergenerational continuities of health could be a way to prevent welfare dependence in future generations.

The welfare burden of adolescent anxiety and depression: a prospective study of 7500 young Norwegians and their families: the HUNT study.

OBJECTIVES: To examine the association between anxiety and depression symptoms in adolescents and their families and later medical benefit receipt in young adulthood. DESIGN: Prospective cohort study. Norwegian population study linked to national registers. PARTICIPANTS: Data from the Nord-Trøndelag Health Study 1995-1997 (HUNT) gave information on anxiety and depression symptoms as self-reported by 7497 school-attending adolescents (Hopkins Symptoms Checklist-SCL-5 score) and their parents (Hospital Anxiety and Depression Scale score). There were 2711 adolescents with one or more siblings in the cohort. OUTCOME MEASURES: Adolescents were followed for 10 years in national social security registers, identifying long-term receipt of medical benefits (main outcome) and unemployment benefits for comparison from ages 20-29. METHODS: We used logistic regression to estimate OR of benefit receipt for groups according to adolescent and parental anxiety and depression symptom load (high vs low symptom loads) and for a one point increase in the continuous SCL-5 score (range 1-4). We adjusted for family-level confounders by comparing siblings differentially exposed to anxiety and depression symptoms. RESULTS: Comparing siblings, a one point increase in the mean SCL-5 score was associated with a 65% increase in the odds of medical benefit receipt from age 20-29 (adjusted OR, 1.65, 95% CI 1.10 to 2.48). Parental anxiety and depression symptom load was an indicator of their adolescent's future risk of medical benefit receipt, and adolescents with both parents reporting high symptom loads seemed to be at a particularly high risk. The anxiety and depression symptom load was only weakly associated with unemployment benefits. CONCLUSIONS: Adolescents in families hampered by anxiety and depression symptoms are at a substantially higher risk of medical welfare dependence in young adulthood. The prevention and treatment of anxiety and depression in adolescence should be family-oriented and aimed at ensuring work-life integration.

School dropout: a major public health challenge: a 10-year prospective study on medical and non-medical social insurance benefits in young adulthood, the Young-HUNT 1 Study (Norway).

BACKGROUND: School and work participation in adolescence and young adulthood are important for future health and socioeconomic status. The authors studied the association between self-rated health in adolescents, high school dropout and long-term receipt of medical and non-medical social insurance benefits in young adulthood. METHODS: Self-rated health in adolescence was assessed in 8795 adolescents participating in the Norwegian Young-HUNT Study (1995-1997). Linkages to the National Education Database and the National Insurance Administration allowed identification of school dropout and receipt of long-term medical and non-medical benefits during a 10-year follow-up (1998-2007). The data were explored by descriptive statistics and by multinomial logistic regression. RESULTS: A total of 17% was registered as being high school dropouts at age 24. The predicted 5-year risk of receiving benefits between ages 24-28 was 21% (95% CI 20% to 23%). High school dropouts had a 5-year risk of receiving benefits of 44% (95% CI 41 to 48) compared with 16% (95% CI 15 to 17) in those who completed high school (adjusted for self-rated health, parental education and sex). There was a 27% school dropout rate in adolescents who reported poor health compared with 16% in those who reported good health. The predicted 5-year risk of receiving any long-term social insurance benefits in adolescents who reported poor health was 33% (95% CI 30 to 37) compared with 20% (95% CI 19 to 21) in those who reported good health. CONCLUSION: The strong association between poor self-rated health in adolescence, high school dropout and reduced work integration needs attention and suggests preventive measures on an individual as well as on a societal level.

Patterns of receptive and creative cultural activities and their association with perceived health, anxiety, depression and satisfaction with life among adults: the HUNT study, Norway.

BACKGROUND: Cultural participation has been used both in governmental health policies and as medical therapy, based on the assumption that cultural activities will improve health. Previous population studies and a human intervention study have shown that religious, social and cultural activities predict increased survival rate. The aim of this study was to analyse the association between cultural activity and perceived health, anxiety, depression and satisfaction with life in both genders. METHODS: The study is based on the third population-based Nord-Trøndelag Health Study (2006-2008), including 50,797 adult participants from Nord-Trøndelag County, Norway. Data on cultural activities, both receptive and creative, perceived health, anxiety, depression and satisfaction with life were collected by comprehensive questionnaires. RESULTS: The logistic regression models, adjusted for relevant cofactors, show that participation in receptive and creative cultural activities was significantly associated with good health, good satisfaction with life, low anxiety and depression scores in both genders. Especially in men, attending receptive, rather than creative, cultural activities was more strongly associated with all health-related outcomes. Statistically significant associations between several single receptive, creative cultural activities and the health-related outcome variables were revealed. CONCLUSION: This population-based study suggests gender-dependent associations between cultural participation and perceived health, anxiety, depression and satisfaction with life. The results support hypotheses on the effect of cultural activities in health promotion and healthcare, but further longitudinal and experimental studies are warranted to establish a reliable cause-effect relationship.

Factors predicting changes in physical activity through adolescence: the Young-HUNT Study, Norway.

PURPOSE: The purpose of this prospective population-based study was to analyze predictors of changes in physical activity (PA) levels from early to late adolescence. METHODS: Data presented are from 2,348 adolescents and their parents who participated in the Nord-Trøndelag Health study (HUNT 2, 1995-1997) and at follow-up in Young-HUNT 2, 2000-2001 Participants completed a self-reported questionnaire and participated in a clinical examination that included measurements of height and weight. RESULTS: Four patterns of PA emerged in the study: active or inactive at both time points (active maintainers, 13%; inactive maintainers, 59%), inactive and became active (adopters, 12%), active and became inactive (relapsers, 16%). Being overweight, dissatisfied with life, and not actively participating in sports at baseline were significant predictors of change regarding PA among boys at follow-up. For girls, smoking, drinking, low maternal education, and physical inactivity predicted relapsers and inactive maintainers. Higher levels of education and more physically active parents at baseline seemed to protect against decreased PA during follow-up for both genders. CONCLUSION: Predictors of change in, or maintaining PA status during adolescence differed by gender. These results suggest that PA-promoting interventions should be tailored by gender and focus on encouraging activity for inactive adolescents and maintenance of PA in those already active.

Adolescents' health-related dietary patterns by parental socio-economic position, the Nord-Trøndelag Health Study (HUNT).

BACKGROUND: Nutrition is among the important determinants of diseases, and the social patterning of early eating habits may offer keys to prevention. We studied associations between selected indicators of adolescents' health-related dietary habits (daily intake of candy, soft drinks, fruit and vegetables) and parental socio-economic position (education, social class and income). METHODS: The material consisted of participants in the adolescent part (Young-HUNT) of the Nord-Trøndelag Health Study during the period 1995-97, 8817 girls and boys aged 13-19 years (89% of all students in junior high schools and high schools in a Norwegian county). Data on parental socio-economic position was available from the adult part of HUNT and Statistics Norway. Cross-sectional data analyses were performed using cross-tables and binary logistic regression. RESULTS: Of the indicators of socio-economic position used, the parent's educational level, in particular the mother's education, showed the highest impact on adolescents' health-related dietary habits. Girls with the least educated mothers had a prevalence odds ratio of 2.5 (1.8-3.3) for drinking soft drinks daily and 0.6 (0.5-0.8) for eating vegetables daily as compared to girls with the most educated mothers. The corresponding numbers for boys were 1.9 (1.5-2.4) and 0.6 (0.5-0.8). Parental social class also showed gradients in adolescents' health-related dietary habits, but there was virtually no gradient by income. CONCLUSION: Higher levels of parental education, in particular the mother's education, are clearly associated with healthier dietary habits among adolescents. This social patterning should be recognized in public health interventions.

Changes in BMI-distribution from 1966-69 to 1995-97 in adolescents. The Young-HUNT study, Norway.

BACKGROUND: The aim of this study was to explore changes in the BMI-distribution over time among Norwegian adolescents. METHODS: Height and weight were measured in standardised ways and BMI computed in 6774 adolescents 14-18 years who participated in the Young-HUNT study, the youth part of the Health-study of Nord-Trondelag County, Norway in 1995-97. The results were compared to data from 8378 adolescents, in the same age group and living in the same geographical region, collected by the National Health Screening Service in 1966-69. RESULTS: From 1966-69 to 1995-97 there was an increased dispersion and a two-sided change in the BMI-distribution. Mean BMI did not increase in girls aged 14-17, but increased significantly in 18 year old girls and in boys of all ages. In both sexes and all ages there was a significant increase in the upper percentiles, but also a trend towards a decrease in the lowest percentiles. Height and weight increased significantly in both sexes and all ages. CONCLUSION: The increased dispersion of the BMI-distribution with a substantial increase in upper BMI-percentiles followed the same pattern seen in other European countries and the United States. The lack of increase in mean BMI among girls, and the decrease in the lowest percentiles has not been acknowledged in previous studies, and may call for attention.
