Abbreviations: BMI, body mass index; BIA, bioelectrical impedance analysis ; SSK, sum of four skinfolds; WC waist circumference; HC, hip circumference;WHR, waist-to-hip ratio.

Data shown as partial correlation coefficient (p value) adjusted for age, and pubertal stage in children.

Logtransformed.

Additional adjustment on height.

All models are also adjusted for a random effect nuclear family variable, for gender and interactions between gender and covariates (age and pubertal stage).
