Factors determining the use of hormone replacement therapy in recent naturally postmenopausal women participating in the French SU.VI.MAX cohort.

The determinants of hormone replacement therapy (HRT) were studied in a cohort of recently postmenopausal women participating, in France, in a nutritional study (SU.VI.MAX Study). Analysis was performed-analysis on 592 women aged 45 years or more, who had undergone natural menopause which appeared in the 2 previous years. No differences were observed in education level, socio-professional categories, marital status, geographic residence, smoking habits, physical activity, or past contraceptive practice. Past regular gynecologic follow-up appeared to be the strongest determinant of HRT use (odds ratio [OR]: 3.18). Women who reported having had at least one of the studied pathologies (past history of breast cancer, phlebitis, anger, uterine fibroma, hypertension, diabetes or hypercholesterolemia), past abundant menstrual blood losses, and with body mass index (BMI) > or = 25 were less likely to be taking HRT than women free of pathology, with no history of past abundant menstrual blood losses and with low BMI (OR respectively of 0.40, 0.64, 0.62). Women over 51.3 years of age were less likely to use HRT than younger women (OR: 0.92). Finally, in our population, while socio-economic level was not a major determinant of HRT use, the regularity of gynecological follow-up before menopause, overweight, and the existence of a definite or possible contra-indication were strong determinants of HRT use.
