Developing Profiles of Postmenopausal Women Being Prescribed Estrogen Therapy to Prevent Osteoporosis

Postmenopausal women with estrogen deficiency are at high risk for osteoporosis. Estrogen therapy has been shown to be effective in preventing postmenopausal bone loss and maintaining bone mineral density. The increasing number of women at risk for osteoporosis and the high cost of treating this condition emphasizes the importance of preventing osteoporosis. This study was designed to identify trends and predictors of estrogen use for osteoporosis prevention among postmenopausal women. A retrospective, cross-sectional study was conducted using Behavioral Risk Factor Surveillance System data (1997–1999). Women 35 years and older who had passed menopause or were currently going through menopause were identified from the states including the BRFSS module that asked questions about estrogen use. Results showed an increasing prevalence in estrogen use from 1997 to 1999 for osteoporosis prevention. In 1999, almost a third of the postmenopausal women surveyed used estrogen to prevent osteoporosis. Prevalence was higher among women 45–64 years of age, whites, and those with higher education levels. Physician counseling on the benefits and risks of estrogen therapy was the strongest predictor of estrogen use for prevention of osteoporosis. Insurance coverage and compliance with other preventive behaviors such as mammograms and Pap smears were also strongly associated with greater estrogen use. However, women who were at risk for acute drinking, not married, overweight or obese, and diabetic were all less likely to receive estrogen therapy for osteoporosis prevention. The relationships demonstrated between estrogen use and demographic characteristics, lifestyle behaviors and health care access and utilization factors underline the importance of targeting specific groups of women for promoting its protective effect against osteoporosis.
