Medication use and climacteric syndrome: a cross-sectional population-based study

Objective: The aim of this study was to evaluate medication use during the climacteric period and assess its association with sociodemographic factors, morbidities, and climacteric symptoms. Methods: Secondary analysis of data from a previous exploratory cross-sectional population-based study, conducted with 749 women (45-60 y), with the help of home interviews. Associations between medication use and climacteric symptoms were analyzed, and their correlations with other variables were made. Univariate analysis was made using the chi(2) test, followed by Bonferroni correction (multiple comparison method). Values were adjusted for age using the polytomic logistic multivariate regression analysis. Using Poisson regression analysis, simple and multiple, we identified the main factors for medication use, with forward stepwise variable selection criteria (95% CI). Results: The mean age was 52.5 years and menopause occurred at 46.5 years (mean). The overall prevalence of medication use was 68.8%. The use of exclusive medications for relieving climacteric symptoms was associated with the absence of diseases (prevalence ratio [PR] = 8.2; 95% CI = 3.5-18.9; P<0.001) and menopause onset between 40 and 44 years (PR = 4.9; 95% CI = 2.0-11.9; P<0.001). Polypharmacy was associated with the highest number of diseases (PR = 10.6; 95% CI = 4.6-24.2; P<0.001) and somatic Menopause Rating Scale (MRS) score >3 (PR = 1.4; 95% CI = 1.01-1.96; P = 0.044). Conclusions: The prevalence of medication use among middle-aged women was high and was associated with the age of menopause onset, chronic diseases, and obesity/overweight status.
