“…25,26 Briefly, the study, a 4-year cluster-randomized controlled intervention study, started in fall 2002, is based on a randomization of the intervention status at school level, with stratification on sociogeographical criteria. The intervention program was designed to increase physical activity in six-graders.…”

“…The theory-based multilevel intervention, open and free of charge, involved not only the school settings but numerous partnerships with three objectives: (1) changing attitudes toward physical activity, (2) promoting social support by parents and educators (3) providing environmental and institutional conditions encouraging the adolescents to use the knowledge and physical activity skills they have acquired. 26 The program included an educational component focusing on physical activity and sedentary behaviors. New opportunities for physical activity were offered at lunchtime, during breaks and afterschool hours, taking into…”

Background: Population-based studies directed at promoting physical activity in youth have shown limited success in obesity prevention. Objective: To assess whether an intervention integrating environmental changes to induce sustained changes in physical activity, prevents overweight in adolescents. Design: Four-year randomized trial started in 2002 in eight middle schools of Eastern France. The intervention, randomized at school level, was designed to promote physical activity by changing attitudes through debates and attractive activities, and by providing social support and environmental changes encouraging physical activity. Subjects: Nine hundred and fifty four 12-year-old six-graders. Measurements: Body mass index (BMI), body composition, physical activity by questionnaire, plasma lipids and glucose, insulin resistance. Results: Intervention students had a lower increase in BMI (P ¼ 0.01) and age-and gender-adjusted BMI (Po0.02) over time than controls. The differences across groups of the age-and gender-adjusted BMI changes (95% confidence interval (CI)) were À0.29 (À0.51; À0.07) kg/m 2 at 3 years, À0.25 (À0.51; 0.01) kg/m 2 at 4 years. An interaction with baseline weight status was noted. The intervention had a significant effect throughout the study in initially non-overweight adolescents (À0.36 (À0.60;À0.11) kg/m 2 for adjusted BMI at 4 years), corresponding to a lower increase in fat mass index (Po0.001). In initially overweight adolescents, the differences observed across groups at 2 years (-0.40 (À0.94; 0.13) kg/m 2 for adjusted BMI) did not persist over time. At 4 years, 4.2% of the initially non-overweight adolescents were overweight in the intervention schools, 9.8% in the controls (odds ratio ¼ 0.41 (0.22; 0.75); Po0.01). Independent of initial weight status, compared with controls, intervention adolescents had an increase in supervised physical activity (Po0.0001), a decrease of TV/video viewing (Po0.01) and an increase of high-density cholesterol concentrations (Po0.0001). Conclusion: Enhancing physical activity with a multilevel program prevents excessive weight gain in non-overweight adolescents. Our study provides evidence that prevention of obesity in youth is feasible.

“…The aim of this cross-sectional study was to investigate the associations between leisure-time physical activity, metabolic syndrome components and two inflammation surrogates (IL-6 and CRP) in adolescents participating in the Intervention Centred on Adolescents' Physical Activity and Sedentary Behaviour Study (ICAPS) [17]. Our hypothesis is that physical activity is favourably related to the metabolic syndrome and low-grade inflammation, independently of adiposity and fat localisation.…”

Aims/hypothesis Physical activity has beneficial effects on symptoms of the metabolic syndrome and low-grade inflammation in adults. These associations have rarely been studied in adolescents. Moreover, it has not been established whether they depend on adiposity, fat localisation and adipokines. Subjects, materials and methods We used cross-sectional data of 640 12-year-old adolescents participating in the Intervention Centred on Adolescents' Physical Activity and Sedentary Behaviour Study (ICAPS). Weight, height, body fat mass and WHR were measured. Metabolic syndrome components, two inflammatory markers (IL-6 and Creactive protein), plasma leptin, adiponectin and soluble TNF-α receptor 1 (sTNF-α R1) were determined. Insulin resistance was estimated by homeostasis model assessment (HOMA) and energy expenditure due to organised leisuretime physical activity (PAE) assessed by questionnaire. Results The metabolic syndrome was present in 5.8% of the adolescents. After adjustment for sex, sexual maturity and socio-economic status, a beneficial relationship between PAE and all metabolic syndrome features was found, but only the associations with HOMA and IL-6 were independent of body fat mass and WHR. Adjusted means from the lowest to the highest tertile of PAE were 1.99, 1.80 and 1.78 for HOMA (p=0.04), and 0.88, 0.69 and 0.70 pg/ml for IL-6 (p=0.02). PAE was inversely associated with leptin, independently of body fat mass and WHR (p<10 −2 ), but not with adiponectin or sTNF-α R1. Further adjustment for adipokines did not change the relationships of PAE with HOMA and IL-6. Conclusions/interpretation In adolescents, physical activity is inversely related to HOMA and IL-6, independently of adiposity and fat localisation. These relationships are not accounted for by adipokines.

“…Reduced entry fees to sport areas, public transport to physical activity sites, and improvements of bicycle lanes around schools were implemented. Four years after randomization, students in the intervention group showed a lower increase in BMI than their age-and gender-adjusted controls, the rate of students practicing physical activity was higher, and screen time was lower in the intervention group (60,61).…”

Obesogenic environments: environmental approaches to obesity prevention

Childhood obesity is a major concern for public health. There are multiple factors (e.g., genetic, social, and environmental) that contribute to unhealthy weight gain. Drawing from findings on "obesogenic environments" and core principles of preventive strategies to reduce health inequalities, this paper gives an overview of recent childhood prevention programs that target aspects of the physical environment ("environmental changes"). Out of the ten reviews we screened (including more than 300 studies), we identified very few that addressed aspects of the environment. We focus here on 14 programs that follow different approaches to environmental changes (e.g., access to/quality of playgrounds, changes in school cafeterias). Altering the environment offers opportunities for healthier behaviors and seems to be an effective strategy to prevent childhood obesity. However, the evaluation of those (mostly) multidimensional interventions does not allow drawing firm conclusions about the single effect of environmental changes. We conclude that obesity prevention programs should combine person-based and environmental approaches.
