Childhood overweight and obesity are increasing public health concerns internationally, contributing to significant long-term health risks. School-based interventions integrating policy and behavioural strategies are needed to address this issue.
Objectives:
This study aimed to evaluate the effects of a school-based intervention informed by the Thailand Healthy Living Strategy (THLS) for weight control and obesity prevention among school-age children.

Cluster randomised controlled trial.
Setting:
Eight primary schools located in Northeastern Thailand.
Methods:
A total of 214 students were randomly assigned to intervention and control groups.

Data were collected using a structured questionnaire at baseline (pretest) and at 1-month posttest following the intervention. Independent and paired
Results:

Conclusions:
The THLS-integrated school-based intervention improved self-efficacy, outcome expectations and obesity prevention practices among schoolchildren. These findings support the implementation of multi-component, school-based strategies involving policy, education, and family engagement to promote healthy lifestyles.
