Key Points Question What is the combined association of weight-for-height z score and body fat with early development in the East Asia and Pacific region? Findings This cross-sectional study of 6815 children found that compared with children with normal weight and normal body fat, children with low body fat, either with wasting or normal weight, were more likely to have poor total, cognitive, language, and socioemotional development independent of confounding factors. Meaning These findings reinforce the potential to use body fat, in addition to weight-for-height z score, to identify children who are not on track developmentally.
