Association between common mental disorders, sleep quality, and menopausal symptoms: a population-based study in Southern Brazil.

OBJECTIVE

To investigate the association between common mental disorders (CMD), sleep quality, and moderate and severe menopausal symptoms in adult women in southern Brazil.

METHODS

This cross-sectional, population-based study investigated a representative sample of 393 women (age 40-69 years) living in an urban area. A standardized and pretested questionnaire that included the Self-Reporting Questionnaire-20 for CMD (Self-Reporting Questionnaire-20 ≥7), the Pittsburgh Sleep Quality Index-BR for sleep disorders (Pittsburgh Sleep Quality Index >5), and the Menopause Rating Scale for moderate/severe menopausal symptoms (Menopause Rating Scale >8) was used for data collection. Unadjusted and adjusted prevalence ratios and 95% confidence intervals (95% CIs) were estimated using robust Poisson regression.

RESULTS

The prevalence of moderate/severe menopausal symptoms in the sample was 58.0% (95% CI 53.0-63.0), the prevalence of CMD was 40.2% (95% CI 35.3-45.2), and the prevalence of poor sleep quality was 49.4% (95% CI 44.3-54.5). CMD and poor sleep quality occurred simultaneously in 34.4% of participants (95% CI 29.6-39.3). Moderate/severe menopausal complaints were significantly more prevalent in women with CMD (P < 0.001) and poor sleep quality (P < 0.001); the presence of both CMD and poor sleep quality increased the likelihood of moderate/severe menopausal complaints threefold. After adjustment, CMD and poor sleep quality remained strongly and significantly associated with moderate/severe menopausal complaints (P < 0.001).

CONCLUSIONS

Considering the complex time-course relationship between CMD, sleep quality, and menopausal symptoms, longitudinal studies should follow women with these issues throughout the menopausal period to identify a possible temporal link between exposures and outcome. : Video Summary:http://links.lww.com/MENO/A554.
