Effectiveness of the "Planning Health in School" Programme on Children's Nutritional Status

Effective interventions for guiding children to change behaviours are needed to tackle obesity. We evaluated the effectiveness of the 'Planning Health in School' programme (PHS-pro) on children's nutritional status. A non-randomised control group pretest-posttest trial was conducted at elementary schools of a sub-urban municipality in Porto's metropolitan area (Portugal). A total of 504 children of grade-6, aged 10-14, were assigned in two groups: children of one school as the intervention group (IG), and three schools as the control group (CG). Anthropometric measures included height, weight, waist circumference (WC), BMI and waist-to-height ratio (WHtR), and lifestyle behaviours (self-reported questionnaire) were assessed at baseline and after PHS-pro. IG children grew significantly taller more than CG ones (p < 0.001). WC had reduced significantly in IG (-0.4 cm) whereas in the CG had increased (+0.3 cm; p = 0.015), and WHtR of IG showed a significant reduction (p = 0.002) compared with CG. After PHS-pro, IG children consumed significantly fewer soft drinks (p = 0.043) and ate more fruit and vegetables daily than CG. Physical activity time increased significantly in IG (p = 0.022), while CG maintained the same activity level. The PHS-pro did improve anthropometric outcomes effectively leading to better nutritional status and appears to be promising in reducing overweight and obesity.
