IntroductionSeveral studies have identified disparities in human papillomavirus (HPV)-related outcomes by nativity status (i.e., U.S.- versus foreign-born). However, few studies have explored whether vaccination differences exist by nativity status. Vaccination disparities have the potential to exacerbate HPV-related cancer disparities in the long term if left unaddressed. Therefore, the authors investigated whether there were significant differences in HPV vaccination initiation (one or more doses) and completion (three or more doses) between U.S.-born and foreign-born men and women.MethodsUsing the 2011 to 2015 waves of the National Health Interview Survey, data from 15,967 U.S. men aged 18-32 years and 23,794 U.S. women aged 18-35 years were analyzed in February 2017. Multivariable logistic regression models were fit to determine whether nativity status predicted (1) HPV vaccination initiation and (2) HPV vaccination completion separately among men and women after adjusting for demographic, socioeconomic, and healthcare factors.ResultsCompared with those born in the U.S., foreign-born men and women had lower prevalence of HPV vaccine initiation and completion. Furthermore, after controlling for covariates, foreign-born men (OR=0.63, 95% CI=0.47, 0.85) and women (OR=0.57, 95% CI=0.49, 0.66) had significantly lower adjusted odds of HPV vaccination initiation compared with their U.S.-born counterparts. Additionally, foreign-born women had significantly lower adjusted odds of HPV vaccination completion (OR=0.56, 95% CI=0.46, 0.69).ConclusionsThe demographic, socioeconomic, and healthcare factors included in this study did not appear to account fully for observed disparities. Future research is needed to understand other factors that may contribute to nativity status disparities in HPV vaccination.Copyright © 2017 American Journal of Preventive Medicine.
