Abstract

Background

This study investigated the long-term impact of the primary school-based multicomponent lifestyle intervention “Lekker Fit!” (LF) on obesity-related outcomes, and studied whether the impact differed between population subgroups.

Methods

Children from the Generation R Study (Rotterdam, the Netherlands) were categorized into the LF group (6 years exposure, between the ages 6/7 to 12/13 years) or regular school group (no exposure). BMI and DXA-derived fat mass were assessed after 4 years of intervention (age 10 years), and 1.5 years post-intervention (age 14 years). A propensity score matching model was fitted to examine the intervention effect on BMI-z-score and percent fat mass, and we tested for differences by sex, pre-intervention weight status, ethnic background, and income.

Results

We found no effect on BMI-z-score [0.06 (95% confidence interval [CI]: −0.04 to 0.17)] and percent fat mass (0.4%-point [95% CI: −0.2 to 1.1]) after 4 years of intervention. 1.5 years post-intervention and after 6 years of exposure, BMI-z-score (0.11 [95% CI: 0.00–0.22]) and percent fat mass (1.1%-point [95% CI: 0.2–1.9]) were significantly higher for children in the LF group. No subgroup differences were found.

Conclusion

Findings suggest the need for obesity prevention programs that extend beyond primary education.

期刊介绍： Pediatric Obesity is a peer-reviewed, monthly journal devoted to research into obesity during childhood and adolescence. The topic is currently at the centre of intense interest in the scientific community, and is of increasing concern to health policy-makers and the public at large. Pediatric Obesity has established itself as the leading journal for high quality papers in this field, including, but not limited to, the following: Genetic, molecular, biochemical and physiological aspects of obesity – basic, applied and clinical studies relating to mechanisms of the development of obesity throughout the life course and the consequent effects of obesity on health outcomes Metabolic consequences of child and adolescent obesity Epidemiological and population-based studies of child and adolescent overweight and obesity Measurement and diagnostic issues in assessing child and adolescent adiposity, physical activity and nutrition Clinical management of children and adolescents with obesity including studies of treatment and prevention Co-morbidities linked to child and adolescent obesity – mechanisms, assessment, and treatment Life-cycle factors eg familial, intrauterine and developmental aspects of child and adolescent obesity Nutrition security and the "double burden" of obesity and malnutrition Health promotion strategies around the issues of obesity, nutrition and physical activity in children and adolescents Community and public health measures to prevent overweight and obesity in children and adolescents.
