Positive body perception and its link to sexual satisfaction in aging women - findings from the Women 40+ Healthy Aging Study

Body weight and body fat are negatively associated with severe dyspareunia in postmenopausal women

AIM

This cross-sectional study aimed to investigate the factors associated with dyspareunia in pre-, peri-, and postmenopausal Japanese women participating in the health and nutrition education program at a menopause clinic.

METHODS

First-visit records of 1702 pre-, peri-, and postmenopausal Japanese women (aged 40-79 years) were analyzed. The relationship between severe dyspareunia and background characteristics was examined by multivariate logistic regression analysis.

RESULTS

The average age of the participants was 53.0 ± 6.3 years. The percentage of women who suffered from severe dyspareunia in the pre-, peri-, postmenopausal, and the hormone therapy receiving groups were 7.1%, 10.5%, 14.6%, and 7.8%, respectively. In the postmenopausal group, the percentage of women affected by severe dyspareunia was the highest between 2 and 5 years after menopause (18.8%), presumably owing to the gradual postmenopausal decline in the number of sexually active women. In sexually active postmenopausal women, body weight, body mass index (BMI), and body fat percentage (BF%) differed significantly among those who had severe dyspareunia (N = 119) and those who did not (N = 334). BMI and BF% were negatively associated with severe dyspareunia, even after adjustment for age and years since menopause (adjusted odds ratio [95% confidence interval]: BMI, 0.894 [0.825-0.964], p = 0.003; BF%, 0.947 [0.909-0.985], p = 0.006).

CONCLUSIONS

BMI and BF% were negatively associated with dyspareunia in sexually active postmenopausal women. In addition to aging, the loss of body weight and fat could negatively impact intercourse in sexually active postmenopausal women.
