Objective: To measure the prevalence rate of hormone replacement therapy (HRT) in the general population and to see whether HRT users report less symptoms, better general health and less use of other palliative than non-users and previous users.
Methods: The study was performed in 1995 as a cross-sectional postal questionnaire study in seven counties in mid-Sweden. The questionnaire was sent to a random sample of 4200 35-64-year-old women of whom 2991 responded. The age distribution of responders and non-responders was similar 49.6+/-8.5 and 49.8+/-8.7 years, respectively. The main outcome measures were vasomotor and general symptoms in relation to menstrual status and HRT.
Results: Fifteen percent were on HRT and 2.3% had stopped treatment during the past year. Thirteen percent used other palliatives. Twenty-five percent of premenopausal women experienced any vasomotor symptoms, as compared with 51% of menopausal and 40% of postmenopausal women. Those on HRT reported higher frequencies than non-users of all symptoms except for sweating during the daytime. In addition, menopausal women experienced more of other symptoms, usually not associated with the menopause, than premenopausal and postmenopausal women. HRT users reported a significantly worse perceived health and they took other palliatives drugs to a larger extent than HRT non-users.
Conclusion: HRT seemed to be effective in relieving some vasomotor symptoms but did not affect the prevalence of other symptoms or perceived health, in spite of the fact that women on HRT supplemented their therapy with palliative drugs to a larger extent than other women.
