Hormone replacement therapy among Danish women aged 45-65 years: prevalence, determinants, and compliance.
OBJECTIVE
To study the prevalence and determinants of consultation for climacteric complaints and the prescription, commencement, and continuation of hormone replacement therapy (HRT) among women aged 45-65 years.


METHODS
A cross-sectional national survey was conducted in Denmark in November 1994 among 1459 women. A total of 1015 women (response rate 69.6%) agreed to participate and provided questionnaire data.


RESULTS
Of the women who had experienced climacteric complaints, 67.4% (95% confidence interval [CI] 63.3, 71.4%) had consulted a physician. More women consulted if their complaints were severe rather than slight-to-moderate (odds ratio [OR] 6.46). Within the total sample, 33.4% of the women had been prescribed HRT at some time, and 94.1% of these women actually had started the treatment. Of the women who started the treatment, 66.3% reported that they still were using HRT at the time of the survey. The current HRT use rate among all respondents was 18.4% (95% CI 16.1, 20.9%). Women with severe or slight-to-moderate climacteric complaints more often reported having had HRT prescribed than women without complaints (OR 23.2 and 5.80, respectively). Furthermore, women who had had a hysterectomy with bilateral oophorectomy more often reported use than women with an intact uterus (OR 10.0). Hormone replacement therapy prescription was associated only weakly with osteoporosis concerns (OR 1.74). Its continuation decreased with age, was higher after hysterectomy and among women who regularly participated in sports or exercised, but was not (P > .05) related to osteoporosis concerns. Age-specific HRT continuation rates decreased among users who reported withdrawal bleeding (P < .05) but not among users who did not experience such bleeding (P > .05).


CONCLUSIONS
In this survey, HRT had been used by one in three women at menopause, mainly for the alleviation of climacteric complaints and hardly ever because of osteoporosis concerns. Although it might be expected that HRT users who are concerned about developing osteoporosis in later life would be likely to continue the treatment for longer than other users, the study results did not bear this out. Continuation depended mainly on having had a hysterectomy and participation in sports and was higher among users with an intact uterus if they had had no withdrawal bleeding.
