To assess the efficacy of a home-based, theory-driven nutritional intervention on anthropometric measures and dietary quality among preschool children with overweight and obesity.
Cluster randomized controlled trial involving 260 children aged 2–5 years with BMI z-scores ≥ +2 and their mothers across 10 health centers in Urmia, Iran (IRCT20090124001580N8).
The intervention group received a six-month multi-component program comprising bi-monthly home visits with nutritional education, low-calorie recipes, and Health Belief Model-based counseling versus standard care.
Primary outcomes included body weight, BMI, BMI z-score, waist circumference, and Modified Youth Healthy Eating Index (MYHEI) scores, analyzed using intention-to-treat linear mixed-effects models.
Children in the intervention group achieved significantly greater reductions compared to controls in body weight (p = 0.006), BMI (p = 0.002), BMI z-score (p = 0.004), and waist circumference (p < 0.001).
Total MYHEI scores and multiple dietary subcomponent scores showed statistically significant improvements in the intervention group compared with the control group (all p < 0.05).
