a
Data are mean (s.d.).
b
P values were calculated using analysis of covariance. Covariates included: age and sex for all; dual-energy X-ray absorptiometry (DXA) fat was adjusted for lean, and lean for fat. While raw scores are reported here for all variables, analyses were based on log scores for weight and total fat. For BMI percentile, a transformation involving ln(highest value + 1)-Y was used.
