ObjectivesChildhood obesity and poor lifestyle practices are emerging as major public health challenges in the Caribbean. Given the fact that a significant part of childhood is spent at school, curriculum-based interventions aimed at improving good dietary and physical activity patterns may provide a useful vehicle for mass inculcation of long-term healthy lifestyle practices. In this study, we evaluated the long-term impact of a brief curriculum based intervention on dietary behaviour, physical activity and knowledge level of primary schoolchildren.MethodsThe study was a randomized, controlled, school-based nutrition education and physical activity intervention. One hundred students each were then randomly assigned to the intervention (IVG) and non-intervention (NIVG) groups and followed-up for 18 months. Participants in the IVG group were exposed to a curriculum consisting of six one-hour modules followed by school-based activities geared at fostering healthy behaviours. Students in the non-intervention group did not receive any modules and were subject to the information available at school on a regular basis.ResultsIn multivariate regression equations controlling for age, gender, body mass index (BMI) and baseline values, intervention was associated with lower intake of fried foods and sodas (p < 0.05) and higher knowledge scores (p < 0.01) 18 months later but not significantly associated with improved physical activity or lower BMI.ConclusionsIn this study, participants in the intervention group reported significantly lower intakes of fried foods and sodas and higher knowledge scores than participants in the control group some 18 months post-intervention independent of age, gender, BMI, ethnicity and the intakes at baseline.
