Summary
Long-term hormone replacement therapy (HRT) use is linked to hysterectomy and positive attitudes towards HRT, not typical health factors. Provider encouragement also plays a key role in prolonged HRT use.
Area of Science:
- Reproductive Health
- Epidemiology
- Women's Health
Background:
- Characteristics differentiating long-term (> or = 10 years) hormone replacement therapy (HRT) users from short-term (<10 years) users and nonusers are not well documented.
- Understanding these differences is crucial for personalized menopausal symptom management and HRT guidance.
Purpose of the Study:
- To investigate the epidemiology of long-term HRT use.
- To identify factors associated with prolonged HRT utilization among postmenopausal women.
Main Methods:
- A random sample survey of 703 women aged 50-80 years was conducted.
- Women with a menopausal duration of > or = 10 years were analyzed, comparing long-term HRT users (29.4%) with short-term (28.1%) and never users (42.5%).
- Associations between HRT duration and demographics, medical history, menopausal symptoms, decision-making information, attitudes, provider encouragement, and healthcare utilization were examined.
Main Results:
- Long-term HRT use was significantly associated with prior hysterectomy (before or after menopause).
- Positive attitudes regarding HRT benefits and perceived provider encouragement were strong correlates of long-term use.
- Factors such as educational attainment, ethnicity, BMI, health status, physical activity, and family medical history did not significantly distinguish long-term from short-term users.
Conclusions:
- Hysterectomy, positive HRT attitudes, and provider encouragement are key factors associated with long-term hormone replacement therapy use.
- Commonly cited correlates of HRT use, like higher education or physical activity, do not predict prolonged utilization.
