The age at menarche and menopause of three groups of Bhotia females living at high altitude, Himalayan region-Uttar Pradesh, North India, were studied. The Johari Bhotia women had earliest menarche (.hivin.X = 15.1 .+-. 1.1 years) as compared to Rang Bhotias, settled (.hivin.X = 15.6 .+-. 0.9 years) and Rang Bhotias, migratory (.hivin.X = 16.0 .+-. 1.0 years). The differences between all these three groups for age at menarche were significant. A trend towards increase in age at menarche with an increase in altitude has been observed, but the total fertility period in the three groups remained similar as early menarche has been found to be associated with early onset of menopause and late menarche with late menopause.
