Age At Menopause in Relation to Reproductive History in Japanese, Caucasian, Chinese and Hawaiian Women Living in Hawaii

Abstract

A multiple regression analysis was undertaken to examine the relationship between age at menopause and selected biological and sociological variables in the reproductive history of Caucasian, Japanese, Chinese and part-Hawaiian post-menopausal women living in Hawaii. The analysis was conducted using the medical history records of 196 caucasian, 181 japanese, 72 chinese and 60 Hawaiian women. Age at menarche, parity and months spent breast-feeding were found to have no significant effect on age at menopause. Regression models were not found to be heterogeneous among ethnic groups and no substantial interaction of ethnic group was found with age at menarche, parity or months spent breast-feeding.
