Background
Lesbians and bisexual women are at risk of human papillomavirus (HPV) from female and male sexual partners throughout the life course.
Objective
To examine the association between sexual orientation identity and HPV vaccination among U.S. women.
Design
We used cross-sectional data 2006–2010 National Survey of Family Growth (NSFG) data.
Setting
U.S. civilian noninstitutional population.
Participants
The NSFG used stratified cluster sampling to establish a national probability sample of 12,279 U.S. women aged 15–44 years. Analyses were restricted to the 3,253 women and girls aged 15–25 years who were asked about HPV vaccination.
Measurements
Multivariable logistic regression was used to obtain HPV vaccine awareness and initiation prevalence estimates adjusted for socio-demographic and health care factors for each sexual orientation identity group.
Results
Eighty-four percent of U.S. women and girls aged 15–25 years reported having ever heard of the HPV vaccine; of these, 28.5% had initiated HPV vaccination. The adjusted prevalence of HPV vaccine awareness was similar among heterosexual, bisexual, and lesbian respondents. Among those who had heard of the vaccine, 8.5% (p = 0.007) of lesbians and 33.2% (p = 0.33) of bisexual women and girls had initiated HPV vaccination compared to 28.4% of their heterosexual counterparts, adjusting for covariates.
Limitations
Self-report, cross-sectional data. Findings may not be generalizable to time periods after 2006–2010 or all U.S. lesbians aged 15–25 years (small sample size for this group).
Conclusions
Adolescent and young adult lesbians may be less likely to initiate HPV vaccination compared to their heterosexual counterparts. Programs should facilitate access to and utilization of HPV vaccination among young lesbians, a marginalized and underserved population.
