Patient-Reported Sexual Function Among Young Adult Cancer Survivors.

Reproductive health and sexual function are important to survivors of Adolescent and Young adult (AYA) cancers. We evaluated the prevalence of sexual dysfunction and factors associated with dysfunction using the Patient-Reported Outcomes Measurement Information System (PROMIS) sexual function (SexFS) measure in AYAs (15-39 years old at diagnosis) enrolled in a cancer survivorship cohort. Using a cross-sectional survey of a tertiary medical center-based cancer survivorship cohort, we determined the mean PROMIS SexFS v1.0 T-scores and prevalence of scores that were indicative of dysfunction (>1/2 standard deviation [SD] below reference population mean). Multivariable generalized linear regression was performed to identify factors associated with lower scores. We identified 284 AYA cancer survivors, most of whom were women (70%). The mean age at survey was 36.0 years (SD = 7.9). Overall, 31% of females and 19% of men had clinically significantly lower scores than the general U.S. population in the domain of interest, and 13% of women and 6% of men had abnormal scores for satisfaction. Twenty-six percent of male AYAs reported erectile dysfunction. The rate of sexual inactivity in the last 30 days was 27%. Low levels of physical activity were associated with lower PROMIS scores for interest in sexual activity in both men and women, and for global satisfaction with sex life in women only. Our results suggest that low interest in sexual activity is common among survivors of AYA cancers. Low levels of physical activity may be associated with lower levels of interest in and satisfaction with sexual activity in this population.
