The long‐term effects of a school‐based intervention on preventing childhood overweight: Propensity score matching analysis within the Generation R Study cohort
Authors' conclusion
Findings suggest the need for obesity prevention programs that extend beyond primary education.
Study context
- Population
- Children from the Generation R Study (Rotterdam, the Netherlands)
- Exposure
- Primary school-based multicomponent lifestyle intervention "Lekker Fit!" (Lekker Fit (LF)) vs regular school
- Outcome
- BMI-z-score and percent fat mass (DXA-derived)
- Follow-up
- After 4 years of intervention (age 10 years) and 1.5 years post-intervention (age 14 years)
Methodological detailsGeneration R Study, population-based cohort
- Generation R Study
- Population-based cohort
Main finding
As reported in the abstract
1.5 years post-intervention, after 6 years of exposure (age 14 years)
LF vs Regular schoolDifference in percent fat mass, %-point (95% CI)
LF
1.1(0.2–1.9)
- Significantly higher in LF
- difference in BMI-z-score 0.11 (95% CI 0.00–0.22)
Observational data: associations, not effects.
Further findings
BMI-z-score and percent fat mass after 4 years of intervention · after 4 years of intervention (age 10 years)
- No intervention effect on BMI-z-score
- 0.06 (95% CI: −0.04 to 0.17)
- No intervention effect on percent fat mass
- 0.4%-point (95% CI: −0.2 to 1.1)
- Propensity score matching
Subgroup differences (sex, pre-intervention weight status, ethnic background, income)
- No subgroup differences were found
