Prevention of overweight in preschool children: results of kindergarten-based interventions
Objective : Given the increasing prevalence of pediatric obesity , we evaluated two kindergarten-based strategies for reducing overweight in preschool children in the Haute-Garonne Department in France . Methods : Kindergartens ( n=79 ) were r and omly assigned to one of the two strategies and followed for 2 years . In the first group ( Epidémiologie et prévention de l’obésité infantile , EPIPOI-1 ) , parents and teachers received basic information on overweight and health , and children underwent screening to identify those with overweight ( body mass index ( BMI ) ⩾90th percentile ) or at risk for overweight ( BMI between 75 and 90th percentile ) , who were then followed up by their physicians . EPIPOI-2 children , in addition , received kindergarten-based education to promote healthy practice s related to nutrition , physical activity and sedentary behaviors . Data on control children from non-intervention kindergartens ( n=40 ) were retrieved from medical records at the Division of School Health . Results : At baseline , groups differed significantly on age and school area ( underprivileged/ not ) . Owing to a significant interaction between school area and group , analyses were stratified by school area . At baseline , groups did not differ on overweight prevalence and BMI z-scores for any school area . After intervention , prevalence of overweight , BMI z-score and change in BMI z-score were significantly lower in intervention groups compared with controls in underprivileged areas . Using multilevel analysis adjusted for potential confounders , a significant effect on overweight prevalence at the end of the study was noted for EPIPOI-1 in underprivileged areas only ( odds ratio and 95 % confidence interval : 0.18 ( 0.07–0.51 ) . In non-underprivileged areas , the gain in BMI z-score was lower in EPIPOI-2 group compared with control and EPIPOI-1 . Conclusion : Our results suggest that simple measures involving increasing awareness on overweight and health , and periodic monitoring of weight and height with follow-up care when indicated , could be useful to reduce  overweight in young children from underprivileged areas . A reinforced strategy with an education component , in addition , may be indicated in children in non-underprivileged areas
