The GReat-Child Trial was a quasi-experimental intervention that has emphasized whole grain as a strategy to manage childhood obesity. Methods:
Two schools in Kuala Lumpur with similar demographic characteristics were assigned as intervention (IG) and control (CG). Eligibility criteria were overweight/obese children aged 9 to 11 years who had no serious co-morbidity. Children who reported consuming wholegrain foods in their 3-day diet-recall during screening were excluded. A total of 63 children (31 IG; 32 CG) completed the entire intervention program. The IG children underwent six 30-min nutrition education lessons and had school delivery of wholegrain food on a daily basis over a 12-week period. Parents of IG children attended 1-h individual diet counseling. Anthropometric outcomes including BMI-for-age z-score (BAZ), body fat percentage and waist circumference were measured at baseline [T0], post-intervention [T1] (3rd month) and follow-up [T2] (9th month). Results:
IG showed significantly lower BAZ (weighted difference: −0.12; 95% CI: −0.21, −0.03; p
= 0.009), body fat percentage (weighted difference: −2.6%; 95% CI: −3.7, −1.5; p
< 0.001) and waist circumference (weighted difference: −2.4 cm; 95% CI: −3.8, −1.0; p
= 0.001) compared to CG. IG reported significantly lower body fat percentage (weighted difference: −3.4%; 95% CI: 1.8, 5.0; p
< 0.001) and waist circumference (weighted difference: −2.1 cm; 95% CI: −3.7, −0.5; p
= 0.014) at T1 compared to T0. Conclusions:
The GReat-Child Trial made a positive impact in managing childhood obesity. It can be incorporated into childhood obesity intervention programs that are being implemented by the policy makers.
