[Psychosocial and socioeconomic factors related to insomnia and menopause: Pró-Saúde Study]

This study evaluated the association between insomnia and menopausal status and the influence of socioeconomic and psychosocial variables on this association in a cross-sectional analysis of 2,190 university employees (the Pró-Saúde Study). A self-administered questionnaire was used, covering menopausal status, complaints of insomnia, common mental disorders, stressful life events, social support, and socioeconomic variables. Odds ratios were calculated using logistic regression with a polytomous outcome. After adjusting for potential socio-demographic confounders, women who had entered menopause more than 60 months previously were more likely to report complaints with sleep (OR 1.53-1.86) as compared to women in menopause for less than 60 months. After adjusting for psychosocial variables, in the first group the ORs decreased to 1.53 (95%CI: 0.92-2.52) for difficulty initiating sleep, 1.81 (95%CI: 1.09-2.98) for difficulty maintaining sleep, and 1.71 (95%CI: 1.08-2.73) for general complaints of insomnia. Psychosocial factors can mediate the manifestation of insomnia among menopausal women.
