Objectives: To assess the prevalence and factors associated with dyspareunia and the lack of sexual intercourse in women between 50 and 70 years cohabiting with their partners.
Methods: This is a descriptive and exploratory cross-sectional study using the snowball technique with prospective data collection using a structured questionnaire to describe multiple aspects of health and sexuality among 266 cohabiting Brazilian couples aged 50 to 70.
Results: The prevalence of lack of sexual activity was 20%. Factors associated with sexual inactivity were female sexual dysfunction (OR: 9.87, 95% CI: 3.24-30.10, P < 0.001), female dissatisfaction with the partner as a lover (OR: 5.86, 95% CI: 2.03-16.88, P = 0.001), male sexual dysfunction (OR: 4.51, 95% CI: 1.60-12.70, P = 0.004), and poor self-rated male health (OR: 3.66, 95% CI: 1.29-10.40, P = 0.015). The prevalence of dyspareunia was 42.3% in the sample of sexually active women. Factors associated with dyspareunia were female sexual dysfunction (OR: 2.7, 95%, CI: 1.26-5.77, P = 0.010), moderate/severe vaginal dryness (OR: 4.67, 95% CI: 2.21-9.87, P < 0.001), and vaginal discomfort (OR: 4.03, 95% CI: 1.77-9.17, P < 0.001).
Conclusions: The results showed that male, female, and dyadic factors were associated with a lack of sexual activity. On the other hand, only female factors were associated with dyspareunia among sexually active couples.
