Factors influencing the prescription of hormone replacement therapy.
OBJECTIVE
To assess the effects of age, bone mineral density, risk of cardiovascular disease, and of breast cancer on the prevalence of hormone replacement therapy (HRT) prescriptions.


METHODS
Seventeen charts of postmenopausal women were summarized. For each chart, we constructed 36 different cases by modifying the age (two levels), the bone mineral density (three levels), the cardiovascular risk (three levels), and the breast cancer risk (two levels). Twelve cases of these 612 files were sent to each Belgian gynecologist (n = 1010).


RESULTS
Overall, HRT was prescribed in 67% of the cases. It was prescribed in 54.6% of women who had a normal bone mass, 67.9% of women with a low bone mass, and 79.0% of those with osteoporosis (P < .001). The prescription rate was higher in younger women (mean +/- standard deviation 55 +/- 4 years) than in their peers who were 10 years older (79.3% versus 55.2%; p < .001). No significant variation was observed in relation to the cardiovascular risk profile or to breast cancer risk.


CONCLUSIONS
Osteoporosis is associated with an increased rate and older age with a decreased rate of HRT prescription, whereas no difference is observed in association with cardiovascular or breast cancer risk.
