| 概要 | ||||||
| 値 | Aims:This study aimed to examine 2D:4D measurements and sexual differences in Japanese toddlers aged1.5 years.Study design and subjects:The digit lengths used to calculate 2D:4D were measured using an easy-to-use pho-tography method. A total of 1045 JECS-A (the Aichi regional sub-cohort of the Japan Environment andChildren's Study) children (males, 523; females, 522) aged 1.5 years were analyzed.Results:The mean ages for the males and females were 575.3 ± 13.1 and 575.9 ± 17.1 days, respectively.Histograms of left and right 2D:4D were normally distributed regardless of sex (left male, 0.909 ± 0.048; leftfemale, 0.913 ± 0.049,d= 0.08; right male, 0.938 ± 0.055; right female, 0.937 ± 0.049,d= 0.02).Because of high dispersion in the data,t-tests did not support a significant sex difference in 2D:4D. Post-hocstatistical power was calculated as 0.124 and the effect size for the sex difference in 2D:4D was 0.036. | |||||
