BFP Body fat percentage
* Two-sided P < 0.05 was considered to be statistically significant according to Pearson’s product moment method
Pearson’s product moment correlation coefficient (r) was calculated between the infant weight change Z-scores and other variables. 0–3 and 3–6 month weight change Z-scores were significantly associated with current BFP in young Japanese women
