Abstract [en]

Background: Research suggests that it may be more stressful for children to grow up in an urban area than in a rural area. Urbanicity may affect physiological stress system functioning as well as the timing of sexual maturation. The purpose of the current study was to investigate whether moderate urbanicity (current and childhood, ranging from rural areas to small cities) was associated with indices of long-term hypothalamic-pituitary-adrenal and hypothalamic-pituitary-gonadal axis functioning (cortisol, cortisone, dehydroepiandrosterone and progesterone levels) and whether sex moderated any associations. Method: Children (N = 92) were all 10 years old and from the Dutch general population. Hair samples were collected and single segments (the three cm most proximal to the scalp) were assayed for concentrations of steroid hormones (LCMS/MS method). Neighborhood-level urbanicity and socioeconomic status were measured from birth through age ten years. Analyses were controlled for neighborhood- and family socioeconomic status, body mass index and season of sampling. Results: The results from multivariate analyses of variance showed no associations between current or childhood moderate urbanicity and hair steroid hormone concentrations. Interaction terms between moderate urbanicity and sex were not statistically significant. Conclusions: Associations between urbanicity and steroid hormone levels may only be detectable in highly urban areas and/or during later stages of adolescence. Alternatively, our findings may have been due to most children being from families with a higher socioeconomic status.

Abstract [en]

Purpose: To investigate the association between sleep duration, sleep initiation difficulties and psychological and somatic complaints. Methods: We used three cohorts of cross-sectional Swedish questionnaire data, from the Health Behaviours of School aged Children (1985/1986, 2005/2006, 2013/2014, n=>18 000, aged 11–15). Specific complaints (e.g. pain) and total complaint load were used as outcomes of sleep duration, sleep initiation difficulties and the combination of them both. Results: Sleeping less than recommended and sleep initiation difficulties were associated with increased odds of specific complaints and belonging to the group with the greatest complaint load. The combination of short sleep duration and sleep initiation difficulties were associated with higher odds than either sleep issue alone. No interaction effects between time and sleep variables were found regarding complaints. Conclusions: The findings support recent sleep duration recommendations. Further, sleep issues warrant a broad health assessment as they indicate a high likelihood of other complaints.

Abstract [en]

In this prospective study, the association between physical activity and subsequent use of antidepressant and hypnotic drug use in adolescents aged 15-16 years was examined. This study is based on information retrieved from the Norwegian Youth Health Surveys (2000-2003) and linked to prescription data from the Norwegian Prescription Database (2004-2013). In total, the study included 10711 participants with a participation rate of 87%. Adolescents were asked how many hours per week they spent on physical activity that made them sweat and/or be out of breath outside of school. Incident psychotropic drug use (outcome measure) was defined as ≥ 1 prescription of one of the following psychotropic drugs: hypnotics and antidepressants registered in the Norwegian Prescription Database. In the crude model for the time period 2004-2007, the odds of incident hypnotic use were lower for those who were physically active 1-2 h per week (OR 0.48-0.64), compared to those who were physically inactive (< 1 h per week). However, the association become non-significant 4-year post-baseline (2008-2010 and 2011-2013). In the crude model for the time periods 2004-2007, 2008-2010 and 2011-2013, the odds of incident antidepressant use were lower for physically active adolescents (2004-2007: OR 0.46-0.71, 2008-2010: OR 0.40-0.67 and 2011-2013: OR 0.37-0.58, compared to those who were physically inactive < 1 h. However, after adjustment for confounders, the association became non-significant in all time periods except in physical activity 5-7 and 8-10 h in the period 2008-2010. Physical activity does not indicate any association with later use of antidepressants, and the significant association with incident hypnotic drug use was for short-term follow-up only and disappeared on longer term follow-up periods. Given the scarcity of longitudinal studies examining the association between physical activity and mental health as well as psychotropic drug use among young people, the current study adds to previous research.

Abstract [en]

Increasing inequality in many societies highlights the importance of paying attention to differences in mental health between the economically disadvantaged adolescents and the non-disadvantaged adolescents. Also important is to understand how changing inequality in society over time influences adolescents’ mental health at the population- and individual-level. The current study examined to what extent increased societal-level income inequality over time, individual-level experiences of economic disadvantage and the cross-level interaction between the two explained Swedish adolescents’ mental health problems from 1995 to 2011. We used repeated cross-sectional data collected 6 times between 1995 and 2011 in Sweden. Each time, approximately 2,500 students in grade 9 completed a questionnaire during the spring semester. The adolescents provided self-report data on the frequency of their experiences of unaffordability of daily leisure activities (concert, movie, sports, and dance). They also reported their psychosomatic symptoms, which was used as a measure of mental health problems. We used the household equalised disposable income Gini coefficient as an indicator of societal income inequality. A real gross domestic product (GDP) per capita was controlled for in order to rule out potential effects of economic growth in the society over time. Multilevel regression analyses were conducted in which students were nested in years of investigations. Adolescents who experienced unaffordability of daily leisure activities reported more mental health problems. Societal income inequality was not directly associated with the adolescents’ mental health. However, among girls the effects of experiences of unaffordability on mental health were stronger for all but one (sports) activities, and among boys for one activity (sports) when societal-level inequality was greater. Individual-level economic disadvantage are detrimental for adolescents’ mental health, both directly and interactively with societal-level economic inequality. Some suggestions for practice and future studies are made for mental health among adolescents in societies where increasing inequality is observed.
