[Sleep quality and sexual functioning in healthy adults]

Abstract

Introduction: There are not enough scientific investigations, especially with a normative population, that show the association between sleep quality and sexual functioning.

Method: 945 healthy individuals, 62% female, 38% male, mean age 34.27 years (standard deviation=15.82), who completed a sociodemographic questionnaire, the Portuguese version of the Oviedo Sleep Questionnaire and the Portuguese version of the Massachusetts General Health Hospital-Sexual Functioning Questionnaire entered this study.

Results: Moderate levels of subjective satisfaction with sleep and low levels of insomnia and hypersomnia were observed. However, women suffer more from these forms of sleep disorders. Subjective satisfaction with sleep quality is positively correlated with overall sexual functioning and all of its dimensions, and insomnia is negatively correlated with sexual functioning and all of its dimensions. From the linear regression analysis, the model of prediction of general sexual functioning was tested according to sleep quality variables, and a statistically significant model was obtained (p <0.001), with the variables in question explaining 7% of general sexual functioning, with β values ??for subjective satisfaction with sleep of 0.189 and for insomnia of -0.140.

Discussion: Based on the results obtained, it is possible to demonstrate that the higher the quality of sleep, the greater the sexual functioning, and that it is negatively influenced mainly by insomnia.
