Locally implemented prevention programs may reverse weight trajectories in half of children with overweight/obesity amid low child-staff ratios: results from a quasi-experimental study in France

Table 6 Analysis of positive 4-year change in weight status among children with overweight/obesity at inclusion (N = 169) according to variations of the VIF program locally implemented in each participating municipality (Model 1), and adjusted for sex, age, and schooling in a deprived area (Model 2)

Significant results are bolded. HE = healthy eating; PA = physical activity; ECA = extracurricular activity; OR = odds ratio; CI = confidence interval
^a Numbered according to the city in which they were locally implemented
^b Classified as low if between 1 and 5 children per adult, and moderate otherwise. Based on occupation (school catering/facilitators of extracurricular activities) and training session attended (physical activity/healthy eating)
