The global prevalence of overweight and obesity among children has increased rapidly in the recent decades, includingin Malaysia. Thus, development of effective interventions to prevent childhood obesity in Malaysia is urgently needed.This paper describes the study design of a 12-week multi-component, school-based nutrition education programme aimedat managing childhood obesity. The objective of Juara Sihat™ is to determine the effectiveness of a nutrition educationprogramme in improving anthropometric status, knowledge, attitude and practice (KAP) of nutrition, eating habits andphysical activity level among overweight and obese children. This quasi-experimental study involves two primary schoolsin Kuala Lumpur with similar demographic characteristics. Eligibility criteria of research participants are overweightand obese children aged 9 to 11 years. The main components of the Juara Sihat™ intervention are nutrition educationclasses on healthy eating and active lifestyle; physical activity sessions; and active involvements of parents and teachers.The control school does not receive any interventions. The primary outcome is BMI-for-age z-score, while other outcomesinclude waist circumference, body fat percentage, KAP of nutrition score, dietary intake, physical activity level, sedentarybehaviour and biochemical profile. Outcome measures will be assessed at three intervals: baseline, post-intervention 1(3-month follow-up), and post-intervention 2 (6-month follow-up). The Juara Sihat™ programme represents a promisingapproach to examining the effectiveness of a school-based childhood obesity intervention with strong empowerment ofParents’ and Teachers’ Association (PTA). We anticipate that this study may provide insights towards the development ofmore effective strategies in formulating childhood obesity interventions.

Introduction: Obesity and physical inactivity among schoolchildren are among the most challenging health problems inMalaysia. The present study aimed to evaluate the sustainedimpact of Juara Sihat programme on physical activity leveland anthropometric status at 18-month post-intervention.Method: Participants of Juara Sihat (n=55) were followed-upat 18 months after completion of the intervention. JuaraSihat intervention was implemented over 12 weeks andfocused on four key components: (i) five one-hour nutritioneducation classes, (ii) four one-hour physical activityeducation sessions, (iii) family involvement, and (iv)empowerment of Parents and Teachers Association.Anthropometric variables (body mass index, body fatpercentage and waist circumference) were measured andphysical activity level was evaluated by using PhysicalActivity Questionnaire for Children (PAQ-C) at baseline (P0),immediately upon completion of intervention (P1), atthree-month post-intervention (P2), and at 18-month postintervention(P3). Analyses of repeated measures analysisof covariance (ANCOVA) with intention-to-treat principlewere applied.Results: Sustained effects were found in BMI-for-age z-scorewhich showed a reduction (P0 2.41±0.84 vs P3 2.27±0.81)and physical activity level which showed positiveimprovements (P0 2.46±0.62 vs P3 2.87±0.76) at 18 monthsafter intervention was completed. Body fat and waistcircumference had increased over the same time period.Conclusion: Overall, this study successfully demonstratedsustained intervention effects of Juara Sihat intervention onBMI-for-age z-score and physical activity, but not on body fatpercentage and waist circumfere
