Do country-level environmental factors explain cross-national variation in adolescent physical activity? A multilevel study in 29 European countries
Background:Â Worldwide, roughly 80% of adolescents fail to meet World Health Organization (WHO) recommendations regarding physical activity, though there is substantial variation in adolescent physical activity prevalence across countries. This study explored whether country-level environmental differences explained cross-national variation in adolescent moderate- to vigorous-intensity physical activity (MVPA) and vigorous-intensity activity (VPA). Method:Â Using the data of 138,014 11- to 15-year-olds from 29 European countries in the 2013/2014 Health Behaviour in School-aged Children (HBSC) study, multilevel regression models examined the influence of four types of country-level environmental factors (physical, socio-cultural, economic, and political) on self-reported individual-level physical activity (MVPA and VPA). Results:Â The environmental variables explained 38% of country-level variance in MVPA and 81% of country-level variance in VPA. Lower annual average national temperature, higher community safety, lower average national household income and a weaker physical education policy were significantly associated with more MVPA. Greater urbanisation, lower annual average national temperature, higher adult physical activity and higher average national household income were significantly associated with more VPA. Conclusions:Â The findings showed that national differences in the physical, socio-cultural and economic environment were related to adolescent physical activity. They point to potential avenues for future research looking at interactions between individual and environmental factors.Publisher PDFPeer reviewe

Exploratory randomised controlled trial of a mindfulness-based weight loss intervention for women
To explore the efficacy of a mindfulness-based weight loss intervention for women. Sixty-two women (ages 19-64; BMI 22.5-52.1) who were attempting to lose weight were randomised to an intervention or control condition. The former were invited to attend four 2-h workshops, the latter were asked to continue with their normal diets. Data were collected at baseline, 4 and 6 months. BMI, physical activity, mental health. At 6 months intervention participants showed significantly greater increases in physical activity compared to controls (p<.05) but no significant differences in weight loss or mental health. However, when intervention participants who reported 'never' applying the workshop principles at 6 months (n=7) were excluded, results showed both significantly greater increases in physical activity (3.1 sessions per week relative to controls, p<.05) and significantly greater reductions in BMI (0.96 relative to controls, equivalent to 2.32 kg, p<0.5). Reductions in BMI were mediated primarily by reductions in binge eating. Despite its brevity, the intervention was successful at bringing about change. Further refinements should increase its efficacy
Mortality benefits of population-wide adherence to national physical activity guidelines: a prospective cohort study
We quantified the mortality benefits and attributable fractions associated with engaging in physical activity across a range of levels, including those recommended by national guidelines. Data were from the Allied Dunbar National Fitness Survey, a population-based prospective cohort comprising 1,796 male and 2,122 female participants aged 16-96 years, randomly selected from 30 English constituencies in 1990. Participants were tagged for mortality at the Office for National Statistics. Cox multivariable regression quantified the association between self-reported achievement of activity guidelines--150 min of at least moderate activity per week, equivalent here to 30 or more 20-min episodes of at least moderate activity per month--and mortality adjusting for age, sex, smoking status, social class, geographical area, anxiety/depression and interview season. There were 1,175 deaths over a median (IQR) of 22.9 (3.9) years follow-up; a mortality rate of 15.2, 95% confidence interval (CI) 14.4-16.1 per 1,000 person years. Compared with being inactive (no 20-min bouts per month), meeting activity guidelines (30+ bouts) was associated with a 25% lower mortality rate, adjusting for measured confounders. If everyone adhered to recommended-, or even low-activity levels, a substantial proportion of premature mortality might be avoided (PAF, 95% CI 20.6, 6.9-32.3 and 8.9, 4.2-13.4%, respectively). Among a representative English population, adherence to activity guidelines was associated with significantly reduced mortality. Efforts to increase population-wide activity levels could produce large public health benefits and should remain a focus of health promotion efforts.The Allied

The HBSC Study in Germany - Study Design and Methodology
Ottova V, Hillebrandt D, Kolip P, et al. Die HBSC-Studie in Deutschland - Studiendesign und Methodik. Das Gesundheitswesen. 2012;74(S 01):S8-S14.The aim of the HBSC-Study is to collect data on the physical and mental health and health behaviour of children and adolescents and to gain a deeper insight into their situation and the specific environment they grow up in. The HBSC-study is an international school-based cross-sectional survey conducted in collaboration with the World Health Organization (WHO). The survey takes place every 4 years since 1982 and is based on a standardised protocol. In Germany the survey was first conducted in 1994 as a pilot study in North Rhine-Westphalia. The German sample is based on a random sample of classes in all public schools in Germany. 11-, 13-, and 15-year-old pupils are surveyed by means of a paper and pencil questionnaire. The questionnaire comprises a broad selection of -topics, including sociodemographics, health and risk behaviours, family, school and peers. The reported trends in the supplement are based on the data from surveys in 2002 (N=5.650), 2006 (N=7.274) and 2010 (N=5.005). The representative samples for each of the survey years are defined as follows: in 2002 the data is based on information collected in 4 Federal States (Berlin, Hesse, North Rhine-Westphalia, Saxony); in 2006 5 states define the German data file (Berlin, Hamburg, Hesse, North Rhine-Westphalia, Saxony). The data from the 2010 survey comprises data from 15 Federal States. The HBSC-data contributes towards a better understanding of the relationship between health and living conditions of young people. The papers in this supplement deliver important insights into the living context of young people and in doing this they provide important information about their health and the long-term effectivenes of public-health-measures
