Objective : To examine the association between age at menopause and mortality in a population-based sample of women in Kangwha, Korea.
Methods : From the Kangwha Cohort, followed-up from 1985 to 1999, the data of the over 55 year old female group(n=3,596) was used in this study to examine the association between age at menopause and mortality. We calculated the all causes mortality risk ratio and the cancer mortality risk ratio by age at menopause grouping using the Cox Proportional Hazards Model with adjustments for age, BMI, smoking, education, chronic disease, self-rated health status, alcohol consumption and age at first birth.
Result and conclusion : Compared to women who had menopause at 45-49 years, the all causes mortality dsk ratio was 1.24 for women with menopause at less than 40 years(95% Cl=1.01-1.53) and 1.05 for women with menopause at over 50 years(95% Cl=0.92-1.20). Also, compared to women who had menopause at 45-49 years, the cancer mortality risk ratio was 1.53 for women with menopause at less than 40 years(95% Cl=0.78-2.98) and 1.17 for women with menopause at over 50 years(95% Cl=0.77-1 .80).
