Abstract
OBJECTIVE: To determine the age at natural menopause in Japanese women. DESIGN: Cross-sectional and retrospective study. SUBJECTS: Two thousand two hundred twenty one women attending gynecological clinics between the ages of 35 and 59 who were born between April, 1929 and March, 1953. MAIN OUTCOME MEASURES: Age of menopause estimated by the rate of the presence of menses at each age, calculated by probit transformation and by reference to the patient's memory. RESULTS: The median age of menopause based on a cross-sectional study was 50.54, and based on patient's memory is 49.47 +/- 3.53 (SD). The presence of fibroma uteri significantly delays the age of menopause (Odds ratio = 9.41).
