The aim of the present study was to evaluate whether Chuvashian women whose maturation was during World War II and the subsequent rehabilitation period were different from women born at other times in terms of age at menarche and age at menopause.
The cohort included 745 Chuvashian females aged 18-90 years; age at menarche (N=653), ranged from 10 to 24 years (mean 15.42+/-2.11). Data regarding menopausal age was obtained from 322 females born between 1915 and 1950 (mean 48.5+/-4.6). We computed descriptive statistics of the age of menopause and the age of menarche for different birth cohorts; we compared the mean values by Student's t-test and the variances by F-test.
The "expected" maturation period of women whose age at menarche >20 and most women whose age at menopause 20 showed normal parameters regarding age at menopause, and women whose age at menopause was
