Non-biological caregivers were excluded from these analyses (n=16). Covariates in adjusted linear regression models include parent and child age, SEIFA disadvantage index, BMI and parent and child sex in models including both sexes.
BMI, body mass index; CC, correlation coefficients for Pearson; CHU9D, Cchild Hhealth Utility 9 Dimension; n, number of biological child–parent pairs with this measure; RC, estimated regression coefficient; SEIFA, Socio-Economic Indexes for Areas.
