Objective

To examine relationships among parity, mode of delivery, and other parturition-related factors with women's sexual function later in life.

Methods

Self-administered questionnaires examined sexual desire, activity, satisfaction, and problems in a multiethnic cohort of women aged 40 years and older with at least one past childbirth event. Trained abstractors obtained information on parity, mode of delivery, and other parturition-related factors from archived records. Multivariable regression models examined associations with sexual function controlling for age, race or ethnicity, partner status, diabetes, and general health.

Results

Among 1,094 participants, mean (standard deviation) age was 56.3 (±8.7) years, 568 (43%) were racial or ethnic minorities (214 African American, 171 Asian, and 183 Latina), and 963 (88%) were multiparous. Fifty-six percent (n=601) reported low sexual desire; 53% (n=577) reported less than monthly sexual activity, and 43% (n=399) reported low overall sexual satisfaction. Greater parity was not associated with increased risk of reporting low sexual desire (adjusted odds ratio [OR] 1.08, confidence interval [CI] 0.96-1.21 per each birth), less than monthly sexual activity (adjusted OR 1.05, CI 0.93-1.20 per each birth), or low sexual satisfaction (adjusted OR 0.96, CI 0.85-1.09 per each birth). Compared with vaginal delivery alone, women with a history of cesarean delivery were not significantly more likely to report low desire (adjusted OR 0.71, CI 0.34-1.47), less than monthly sexual activity (adjusted OR 1.03, CI 0.46-2.32), or low sexual satisfaction (adjusted OR 0.57, CI 0.26-1.22). Women with a history of operative-assisted delivery were more likely to report low desire (adjusted OR 1.38, CI 1.04-1.83).

Conclusions

Among women with at least one childbirth event, parity and mode of delivery are not major determinants of sexual desire, activity, or satisfaction later in life.
