Model 1: Adjusted for child’s sex and age at DXA measures
Model 2: Additionally adjusted for maternal race/ethnicity, education, age, pre-pregnancy BMI, marital status, and smoking status
LTPA = leisure time physical activity, derived by adding self-reported walking, light/moderate and vigorous physical activity; SD = standard deviation;
CI = confident interval
