Abstract
Objective: To characterise women with no response or with a good response to hormone replacement therapy (HRT), evaluated by change in bone mineral density (BMD). Design: Nested case-control study within a comprehensive cohort study. Subjects and methods: In the Danish Osteoporosis Prevention Study (DOPS), perimenopausal women were allocated to either HRT or no HRT. In the present study, we included 466 women who had been treated with HRT for 5 years and 466 untreated women from the same cohort. Non-responders were women in the treatment group, who decreased in BMD more than the mean decrease observed in the untreated group. Good responders were women with a larger increase in BMD than the upper 95% percentile of untreated women. Baseline characteristics were evaluated as predictors of response to HRT. Results: 8.4 and 5.6% were classified as non-responders, whereas 25 and 57% were good responders according to changes in BMD of the femoral neck and lumbar spine, respectively. Combining measuring sites, 2.6% were non-responders and 20% were good responders. Non-responders at the femoral neck were more often smokers and had a lower spine BMD. Good responders were older, had a higher body weight, and higher alcohol consumption. In addition, good responders at both measurements sites had a lower BMD at the total hip. Conclusion: A favourable BMD response to HRT can be expected in most post-menopausal women especially if they are non-smokers with a moderate - as opposed to low - alcohol intake, a high body mass and a low initial hip BMD.
