Objective: To examine dietary factors including nutrient intakes and infant feeding practices associated with adiposity rebound（AR）in children aged 1～6 years. Methods: We analyzed data from 48 subjects 1～6 years old with complete 24-h recall and anthropometric measures. Timing of AR was assessed by visual inspection from continuous linear body-mass index（BMI）changes. Children were divided into two groups based on the AR stage: early AR（3～5 years）and later AR （after 6 years）groups. A statistical analysis was performed using SPSS 12.0, ANOVA was used to perform comparisons between subgroups, continuous variables are presented as the mean and were compared by an independent-sample -test, and p＜ 0.05 was accepted as the significance level. Results: The mean age of AR was 5 years for children in this study. Regardless of gender, children in the early AR group（n = 28）had a significantly higher BMI than the later AR group（n = 20）. Nutrient intake levels in the two groups did not significantly differ, but the mean energy intake of the early AR group was higher than that of the later AR group at 1 year old. We also found that there was higher energy intake at less than 4 months old in analyses of children who stopped being breastfed and those who began to use formula. Within each sub-analysis, the mean energy intake in the early AR group was higher than that of the later AR group. Therefore, these findings suggest that the AR status was related to early infant feeding practices. Conclusions: Results suggest that infant feeding practices affected AR in children in this prospective cohort.
