Abstract: We conducted a randomized controlled trial (RCT) to test whether updating nutrition information sets of parents along with nudges reduces excess body fat among primary schoolchildren in urban Vietnam. Parents of overweight or obese children were randomly offered a nutrition consultation that led to goal setting with soft commitment, BMI-for-age report card, and weight scale. After six months, the intervention reduced body fat, waist circumference, and the likelihood of being overweight or obese, which are partly explained by improvements in diets and diet-related parental perceptions. Anthropometric improvements are concentrated among girls—partly operating through achievement of dietary goals—and persisted after 22 months.
