To estimate sexual orientation associated disparities in sexually transmitted infection (STI)-related outcomes across multiple dimensions of sexual orientation. Using pooled 2011-2017 National Survey of Family Growth data (  = 16,854), we performed bivariate and multivariable logistic and multinomial regression analyses to estimate associations between sexual identity, behavior in the past 12 months, and attraction, and past-year STI treatment, receipt of the human papillomavirus (HPV) vaccine, and age at first HPV vaccination in cisgender women. Bisexual-identified women (adjusted odds ratio [AOR] = 1.53, 95% confidence interval [CI] = 1.10-2.14) and who were sexually active with both men and women in the past 12 months (AOR = 1.64, 95% CI = 1.03-2.55) had significantly higher odds of past-year STI treatment, compared with their nonsexual minority counterparts. Lesbian-identified women (AOR = 0.44, 95% CI = 0.27-0.75) and women with female partners only (AOR = 0.32, 95% CI = 0.12-0.87) had significantly decreased odds of having initiated the HPV vaccine compared with their heterosexual counterparts. Women with both male and female partners who initiated the HPV vaccine had significantly higher odds of having received the vaccine during the latest age range, 18-25 years old (AOR = 2.32, 95% CI = 1.21-4.45) compared with women with male partners only. Sexual minority women continue to be at risk for poor sexual health outcomes, and these outcomes differ by specific components of sexual orientation.
