Human papillomavirus vaccination: a quantitative cross-sectional study of perceived barriers, influential advisors, and acculturation among Chinese college students aged 18-26 in the USA.

ABSTRACT

HPV vaccines are highly effective in preventing HPV-associated cancers; however, HPV vaccination uptake is low among Chinese students studying at U.S. colleges. The purposes of this study were to evaluate (a) perceived barriers and influential others trusted for advice regarding HPV vaccination and (b) factors (i.e. HPV vaccination, acculturation) related to barriers and influential advisors among 18- to 26-year-old Chinese students attending U.S. colleges. We used a cross-sectional design to obtain self-reported data in 2019 from a chain-referral sample of 213 Chinese students. Among 125 respondents who were unvaccinated or partially vaccinated, the reported barriers to receiving the HPV vaccine included (a) lack of recommendations from a healthcare provider, (b) lack of risk perception for HPV infection, and (c) limited knowledge about HPV vaccination locations. The influential advisors for receiving HPV vaccination were doctors, parents, self, nurses, and same-sex friends. Multivariate analysis revealed that unvaccinated respondents were more likely to report the following barriers to HPV vaccination (a) lack of recommendations from a healthcare provider, (b) lack of risk perception for HPV infection, (c) limited knowledge about vaccination locations, and (d) uncertainty about effectiveness. High Asian identified respondents were more likely to perceive barriers related to limited knowledge about vaccination locations and uncertainty about effectiveness, while they were less likely to state nurses as influential advisors. Individuals who received one or more HPV vaccine doses were more inclined to view same-sex friends and nurses as influential advisors for HPV vaccination. The influence of culture on preferences for information sources, such as specific providers and provider gender, needs to be addressed. Programs designed to decrease barriers and improve HPV vaccination among Chinese students should also focus on acculturation status.
