[Sleep quality and sexual functioning in healthy adults]

Area of Science:

• Sleep Medicine
• Sexual Health
• Psychology

Background:

• Limited research exists on the association between sleep quality and sexual functioning, particularly in normative populations.
• Understanding this relationship is crucial for public health initiatives addressing both sleep and sexual well-being.

Purpose of the Study:

• To investigate the correlation between sleep quality parameters and sexual functioning in a healthy adult population.
• To determine the predictive value of sleep quality on overall sexual functioning.

Main Methods:

• A cross-sectional study involving 945 healthy participants (62% female, 38% male, mean age 34.27 years).
• Data collected using a sociodemographic questionnaire, the Oviedo Sleep Questionnaire, and the Massachusetts General Health Hospital-Sexual Functioning Questionnaire (Portuguese versions).

Main Results:

• Moderate subjective sleep satisfaction and low levels of insomnia and hypersomnia were reported, with women experiencing higher prevalence of sleep disorders.
• Subjective sleep satisfaction positively correlated with overall sexual functioning and its dimensions.
• Insomnia negatively correlated with sexual functioning. Sleep quality variables explained 7% of general sexual functioning (p <0.001).

Conclusions:

• Higher sleep quality is associated with enhanced sexual functioning.
• Insomnia emerged as a significant negative predictor of sexual functioning.
• Findings underscore the importance of addressing sleep quality for optimizing sexual health.
