^aValues are standardized regression coefficients [95% confidence interval] and represent the difference in standard-deviation scores for fat mass measures at 6 years per 1-standard-deviation scores increase in body mass index and subcutaneous fat mass measures at 1.5 months. Body mass index = weight/height². Total subcutaneous fat mass = biceps + triceps + suprailiacal + subscapular skinfold thicknesses. Central-to-total subcutaneous fat mass ratio = (suprailiacal + subscapular skinfold thicknesses)/total subcutaneous fat mass. Fat mass index = total fat mass/height³. Central-to-total fat mass ratio = trunk fat mass/total fat mass. Android-to-gynoid fat mass ratio = android fat mass/gynoid fat mass.

^bModels are adjusted for maternal age, educational level, parity, pre-pregnancy body mass index, smoking habits during pregnancy, and child’s gestational age-adjusted birthweight standard-deviation scores, breast feeding duration, timing of introduction of solid foods, and TV watching time.

^cP-value for interaction of child´s sex with fat mass measures at 1.5 months >0.05.
