Non-biological caregivers were excluded from these analyses (n=17). Covariates in adjusted linear regression models include parent and child ages, BMI and Disadvantage Index, and parent and child sexes in models including both sexes.
CC, correlation coefficient; n, number of biological child–parent pairs with this measure; RC, regression coefficient.
