Objective: This study aims to understand the epidemiological characteristics of Brazilian menopausal women, and their view on menopause hormone therapy (MHT).
Methods: A national cross-sectional study with 1500 women between 45 and 65 years old was carried out through questionnaires.
Results: The overall median age of participants was 52 [47-56] years, and 55 [52-59] years for the postmenopausal subgroup. Menstrual irregularity started at median age 46 [44-49] years. Median menopause age was 48 [45-51] years with no differences between socioeconomic classes. The prevalence of any climacteric symptoms was 87.9% and hot flashes started at median age 47 [45-50] years. Among women in menopause/menopausal transition, 52.1% received any medical prescription, and MHT was recommended for 22.3%. Among those who started MHT, 45.4% were still using the treatment and the median duration of use was 8 months, but different among socioeconomic classes (24 months for class A against 3 months for class D/E).
Conclusions: In this first Brazilian national population-based study on menopause and MHT, it was observed that, in spite of being symptomatic when entering menopause around 48 years of age, only a small part of Brazilian women started MHT and the median duration of treatment was less than 1 year, but the duration was higher for higher socioeconomic class.
