Predictors associated with sleep quality, erectile function, and quality of life in men

Men’s health involves multiple factors in the health-disease process. This study aimed to evaluate the association between sleep quality, sexual function, and quality of life, as well as the predictors associated with these variables in men aged 25 to 59 years. This was a cross-sectional, exploratory, and analytical study that assessed 379 men in the municipality of Três Lagoas, state of Mato Grosso do Sul, Brazil. Data were collected using a structured instrument comprising sociodemographic and clinical variables, the International Index of Erectile Function (IIEF), the Pittsburgh Sleep Quality Index (PSQI), and the WHOQOL-BREF for quality of life assessment. Analysis included Spearman’s correlation test, forward logistic regression, and linear regression. A strong association was found between sexual function and age (p < 0.01) and marital status (p = 0.02), in addition to negative impacts on quality of life due to chronic diseases and risk behaviors related to the hegemonic model of masculinity. Sleep quality was correlated with erectile function (p < 0.01) and medication use (p < 0.01), indicating a lower quality of life (-0.15). These findings reinforce the need for professional preparedness in men’s healthcare and for strategies that improve quality of life, sleep, and sexual function, essential factors for comprehensive men’s health.
