PI/BMI trajectories from birth to ten years and their association with Ln of DXA-assessed total body fat mass at age 15 years, with multiple imputation, adjusted for age, previous periods of PI/BMI change and confounders.

All variables were standardised prior to analysis. Coefficients represent the standard deviation change in DXA-assessed total body fat mass associated with a one standard deviation increase in the rate of PI/BMI change.
Bold text indicates that PI/BMI is, on average, declining during that period.
Adjusted for age, previous periods of PI/BMI change, height, height squared, gender, maternal and partner education, household social class, maternal age, height, gestational age at birth, maternal and partner BMI, maternal and partner smoking in pregnancy, age at clinic attendance, and pubertal stage at measurement of outcome.
PI/BMI change periods:
BMI change 2–5y: 24 and 60 months for boys, 24 and 56 months for girls.
BMI change 5–5.5y: 60 and 65 months for boys, 56 and 67 months for girls.
BMI change 5.5–6.5y: 65 and 75 months for boys, 67 and 73 months for girls.
BMI change 6.5–7y: 75 and 81 months for boys, 73 and 79 months for girls.
BMI change 7–8.5y: 81 and 103 months for boys, 79 and 105 months for girls.
BMI change 8.5–10y: 103 and 120 months for boys, 105 and 120 months for girls.
