Factors Associated with HPV Vaccination Among Middle-Aged Adults in the United States.

Objective: To examine prevalence of partial and complete HPV vaccination among middle-aged adults and factors associated with vaccination status.

Study design: Nationally representative cross-sectional survey.

Setting: United States.

Methods: Cohort includes adults aged 30 to 44 years from 2018 to 2022 Behavioral Risk Factor Surveillance System (BRFSS) survey who completed questions about HPV vaccination status. Survey-weighted multivariable logistic regression was utilized to explore factors associated with partial and complete HPV vaccination status.

Results: In this nationally representative cohort of 26,470 US middle-aged adults, 15.8% [95% confidence interval [CI]: 15.1%-16.6%] reported any HPV vaccination, and 6.5% [95% CI: 6.0%-7.0%] reported complete HPV vaccination. On multivariable regression, younger age, female sex, residence in the West or Northeast, higher educational attainment, unmarried status, having a personal healthcare provider, and gay or lesbian sexual orientation were associated with increased likelihood of vaccination. Race was variably associated with vaccination status. Annual income, insurance status, cancer history, head and neck cancer history, and time of last physician checkup were not associated with HPV vaccination status.

Conclusion: HPV vaccination among middle-aged adults who were not previously vaccinated should be based on risk for new HPV infection and possible benefits of vaccination. While our analysis shows that consideration of personal factors likely plays a role in HPV vaccination in this cohort, we also find that gaps in vaccination may exist due to other socioeconomic disparities between sexes, educational attainment levels, racial/ethnic groups, geographic regions, and access to a personal healthcare provider. These factors' influence suggests potential room for improved public health measures.
