Qualidade do sono e funcionamento sexual em adultos saudáveis / Sleep quality and sexual functioning in healthy adults

INTRODUÇÃO: Não existem investigações científicas suficientes, sobretudo com população normativa, que evidenciem a associação entre a qualidade do sono e o funcionamento sexual. MÉTODO: Participaram deste estudo 945 indivíduos saudáveis, 62% mulheres, 38% homens, média de 34,27 anos (desvio‐padrão=15,82), que preencheram um questionário sociodemográfico, a versão portuguesa do Questionário de Sono de Oviedo e a versão portuguesa do Questionário de Funcionamento Sexual do Massachusetts General Health Hospital. RESULTADOS: Verificaram‐se níveis moderados de satisfação subjetiva com o sono e níveis baixos de insónia e hipersónia. No entanto, as mulheres sofrem mais deste tipo de perturbações do sono. A satisfação subjetiva com qualidade do sono está positivamente correlacionada com o funcionamento sexual geral e todas as suas respetivas dimensões e a insónia está negativamente correlacionada com o funcionamento sexual e todas as suas respetivas dimensões. Da submissão dos itens à análise de regressão linear, testou‐se o modelo de predição do funcionamento sexual geral em função das variáveis da qualidade do sono, tendo‐se obtido um modelo estatisticamente significativo (p < 0,001), sendo que as variáveis em questão explicam 7% do funcionamento sexual geral, com valores β para a satisfação subjetiva com o sono de 0,189 e para a insónia de ‐0,140. DISCUSSÃO: Com base nos resultados obtidos, é possível comprovar que quanto maior a qualidade do sono, maior é o funcionamento sexual e que o mesmo é influenciado negativamente sobretudo pela insónia

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

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 ß 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.
