a. Average growth rates †

b. The differences in growth rates by BMI status at 4–5 years*†‡

c. The differences in growth rates by sex*†§

Each beta coefficient for periodic growth rate and their standard error bars were presented.

*Difference of growth rates between groups, p < 0.05.

†Piecewise- linear mixed model with random intercept was fitted with adjustment for breast feeding, residential area, gestational age, birth weight, maternal education and occupation (n=8,490).

‡BMI status was defined by top tertile of BMI for age Z score at 4–5 years; differences by BMI status (n=8,490) = Growth rate of high BMI group - growth rate of low BMI group.

§Differences by sex in the high BMI group (n = 2,133) = Growth rates of boys - growth rates of girls in the high BMI group.
