Objective
To examine relationships between 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 (±SD) age was 56.3 (±8.7) years, 568 (43%) were racial or ethnic minorities (214 Black, 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 [AOR]=1.08, CI=0.96-1.21 per each birth), less than monthly sexual activity (AOR=1.05, CI=0.93-1.20 per each birth), or low sexual satisfaction (AOR=0.96, CI=0.85-1.09 per each birth). Compared to vaginal delivery alone, women with a history of cesarean delivery were not significantly more likely to report low desire (AOR=0.71, CI=0.34-1.47), less than monthly sexual activity (AOR=1.03, CI=0.46-2.32), or low sexual satisfaction (AOR=0.57, CI=0.26-1.22). Women with a history of operative-assisted delivery were more likely to report low desire (AOR=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.
