Risk perception and trust in the relationship between knowledge and HPV vaccine hesitancy among female university students in China: a cross-sectional study

Abstract

BackgroundCervical cancer poses a heavy health burden in China, with the second highest incidence and mortality rate among female tumors, yet human papillomavirus (HPV) vaccination rate among female university students remain remains low. This study conducted a cross-sectional survey to assess the degree of HPV vaccine hesitancy among female university students and to explore the potential association between knowledge, risk perception, trust, and HPV vaccine hesitancy.MethodsA total of 1,438 female university students from four Chinese cities were recruited through stratified, multistage, cluster sampling method. The mediation model was constructed using the Bootstrap method, introducing trust and risk perception as mediating variables to examine the effect of knowledge on HPV vaccine hesitancy.ResultsThe study found that 8.9% (95%CI:7.4%∼10.4%) of the female university students exhibited HPV vaccine hesitancy. Pearson’s correlation analysis revealed a negative association between vaccine hesitancy and knowledge, risk perception, and trust. The mediation model showed that knowledge had significant indirect effects on HPV vaccine hesitancy through trust (indirect effect: -0.224, 95% CI: -0.293 ∼ -0.167) and risk perception (indirect effect: -0.013, 95% CI: -0.033 ∼ -0.002).ConclusionHPV vaccine hesitancy among female university students has mitigated, but still needs to be addressed. In addition, trust and risk perception are mediators mediating the relationship between knowledge with HPV vaccine hesitancy. Therefore, there is a need to strengthen public health education to improve knowledge, with a particular focus on providing information about trust and risk perception to reduce HPV vaccine hesitancy.
