Abstract

Objective To determine the current timing of girls' sexual maturity in Shanghai. Methods A school-based cross-sectional survey was conducted among 1 675 girls aged 4~19 years old in Shanghai.Puberty was staged according to the Tanner.Mean age at entry into each pubertal stage was calculated by probit analysis. Results Median age at entry into Breast stage Ⅱ~Ⅴ was 8.26 yrs,10.62 yrs,12.88 yrs and 16.64 yrs,respectively.Median age at entry into Pubic hair stage Ⅱ~Ⅴ was 11.48 yrs,12.71 yrs,15.23 yrs and 19.07 yrs,respectively.Media age of onset of armpit hair development was 11.71 yrs.And median age of menarche was 12.09 yrs. Conclusions In comparison to those living in others countries,onset of breast development of girls in Shanghai is relatively earlier,with onset of pubic hair being later and progression of sexual development being slower.Further dynamic observational study of secular change of menarche age is needed.
