Background: Overweight and obesity prevention in childhood and adolescence represent a priority for public health; school is a privileged place for health promotion interventions. Objectives: The study aimed to test the effectiveness of a multicomponent 5-month intervention on the habits of primary school children, making the families aware of the importance of healthy choices. Methods: Two hundred nine children attending the fourth class of primary school, divided into interventional (n = 103) and control arm (n = 106) were included in the study. In the intervention group, parents and teachers received more intense lifestyle counseling, associated with weekly motivational telephone calls to families to motivate further their lifestyle changes. Standard deviation score (SDS) body mass index (BMI) was the primary outcome measure; on open-air games and TV watching were secondary outcomes. Results: At baseline, no differences were observed between groups. At 8-month follow-up, mean SDS BMI had decreased by 0.06 units in the intervention arm and increased by 0.12 in controls (time x treatment ANOVA, P < 0.002). Outdoor activities increased from 6.23 h week-1 to 9.93 in the intervention group (P < 0.001), not in controls. This change was associated differences in TV watching from baseline (intervention, -0.96 h week-1; P = 0.037; controls, +1.33 h week-1; P = 0.031). Conclusion: A multicomponent school-based intervention addressing the needs of children, teachers and families produced a significant and favourable short-term effect on overweight/obese schoolchildren.

Abstract

Background: Overweight and obesity prevention in childhood and adolescence represent a priority for public health; school is a privileged place for health promotion interventions. Objectives: The study aimed to test the effectiveness of a multicomponent 5-month intervention on the habits of primary school children, making the families aware of the importance of healthy choices. Methods: Two hundred nine children attending the fourth class of primary school, divided into interventional (n = 103) and control arm (n = 106) were included in the study. In the intervention group, parents and teachers received more intense lifestyle counseling, associated with weekly motivational telephone calls to families to motivate further their lifestyle changes. Standard deviation score (SDS) body mass index (BMI) was the primary outcome measure; on open-air games and TV watching were secondary outcomes. Results: At baseline, no differences were observed between groups. At 8-month follow-up, mean SDS BMI had decreased by 0.06 units in the intervention arm and increased by 0.12 in controls (time x treatment ANOVA, P < 0.002). Outdoor activities increased from 6.23 h week-1 to 9.93 in the intervention group (P < 0.001), not in controls. This change was associated differences in TV watching from baseline (intervention, -0.96 h week-1; P = 0.037; controls, +1.33 h week-1; P = 0.031). Conclusion: A multicomponent school-based intervention addressing the needs of children, teachers and families produced a significant and favourable short-term effect on overweight/obese schoolchildren.
