Menopause could be involved in the pathogenesis of muscle and joint aches in mid-aged women

Background: Muscle and joint aches (MJA) are frequently observed among menopausal women. They impair quality of life and are a burden to the healthcare system. Objective: To analyze the relation between MJA and several variables related to the menopause. Methods: In this cross-sectional study, 8373 healthy women aged 40-59 years, accompanying patients to healthcare centers in 18 cities of 12 Latin American countries, were asked to fill out the Menopause Rating Scale (MRS) and a questionnaire containing personal data. Results: Mean age of the whole sample was 49.1 ± 5.7 years, 48.6% were postmenopausal and 14.7% used hormone therapy (HT). A 63.0% of them presented MJA, with a 15.6% being scored as severe to very severe according to the MRS (scores 3 or 4). Logistic regression model determined that vasomotor symptoms (OR: 6.16; 95% CI, 5.25-7.24), premature menopause (OR: 1.58; 95% CI, 1.02-2.45), postmenopausal status (OR: 1.43; 95% CI, 1.20-1.69), psychiatric consultation (OR: 1.93; 95% CI, 1.60-2.32) and the use of psychotropic drugs (OR: 1.35; 95% CI, 1.08-1.69) were significantly related to the presence of severe-very severe MJA. Other significant variables included: age, tobacco consumption and lower education. Self perception of healthiness (OR: 0.49; 95% CI, 0.41-0.59), private healthcare access (OR: 0.77; 95% CI, 0.67-0.88) and HT use (OR: 0.75; 95% CI, 0.62-0.91) were significantly related to a lower risk for the presence of severe-very severe MJA. Conclusion: In this large mid-aged sample the prevalence of MJA was high, which was significantly associated to menopausal variables, especially vasomotor symptoms. This association may suggest a potential role of mid-life female hormonal changes in the pathogenesis of MJA.
