In this cross-sectional study which has been done between 2004 and 2005, women aged equal or more than 35 years living in districts of Tehran were selected by multistage randomized cluster sampling. For each woman a questionnaire was completed which consisted of a series of questions concerning weight, height, age at menopause, socioeconomic status, age at menarche, age at first pregnancy, regularity of menstrual cycles, parity, age at menopause of the mother and the sister (if existing), smoking, occupational and marital status. The data gained from each questionnaire was analyzed using t-test and Mann Whitney via SPSS 13 soft ware. Results. In this study, 7711 questionnaires were completed. Mean age of interviewed women was 48.48 (SE=0.18) years. In this study, 2462 women among 7711 interviewed women had natural menopause at interview time. The mean age of menopause onset was 47.71 (SE=0.11) years. There was statistically significant correlation between the age of menopause and the number of parities (r=0.08, P=0.001), regularity of menstrual cycle (P=0.0001) and age of their mother at menopause (r =0.32, P=0.0001). Conclusion. This study showed that the mean age of menopause onset was 47.71 (SE=0.11) years and regularity in menstrual cycle, mother’s age at menopause and multiparity in Iranian women living the Tehran had significant correlation with age at menopause.
