Rapid weight gain in early infancy is associated with adult body fat percentage in young women

Table 2 Correlation coefficients of infant weight change Z-scores versus BMI and body fat percentage of young women

Demographic and physical characteristics	n	BFP		BMI

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
