Coverage of HPV Vaccination and Influencing Factors Among Female College Students in Northern China

Background: Despite the significant global disease burden associated with HPV infection, the vaccination coverage among female college students in China remains suboptimal. This study aimed to examine HPV vaccination coverage, knowledge levels, and determinants influencing vaccination behavior among female college students in northern China, utilizing the Health Belief Model (HBM) as a theoretical framework. Methods: A cross-sectional online survey was conducted from December 2024 to January 2025, involving 4076 female students from six universities in Jinan, China. The participants were categorized into three groups: vaccinated (VG), willing-to-vaccinate (WTG), and unwilling-to-vaccinate (UTG). Data on sociodemographic characteristics, HPV knowledge, health beliefs, and vaccination behavior were analyzed using ANOVA, chi-square tests, correlation analysis, and multivariate logistic regression. Results: The vaccination rate was 18.11%, with 40.19% expressing willingness to vaccinate and 41.71% expressing unwillingness. Vaccinated students demonstrated higher levels of HPV knowledge (6.66 ± 2.67 compared to 4.76 ± 3.10 in the UTG, p < 0.001) and were predominantly from urban areas (OR = 0.64, p < 0.001). The key determinants of vaccination uptake included perceived benefits (OR = 1.54, p < 0.001), perceived barriers (OR = 3.34, p < 0.001), self-decision-making ability (OR = 1.80, p < 0.001), and social motivation (OR = 0.21, p < 0.001). Notably, increased knowledge was associated with vaccine hesitancy in the WTG group (OR = 0.45, p < 0.001), indicating that information overload may adversely affect decision-making processes. Structural barriers, such as cost (42.63%), safety concerns (46.59%), and misconceptions (e.g., 57.76% cited "no sexual activity" as a reason for refusal), significantly impeded vaccine uptake. Conclusions: The low coverage of HPV vaccination is indicative of deficiencies in knowledge, socioeconomic disparities, and cultural perceptions. Tailored interventions should focus on educational efforts to correct misconceptions, provide subsidized access to vaccines, and implement empowerment strategies that enhance self-efficacy and informed decision-making. Policymakers should incorporate these findings into national cervical cancer prevention programs to address the gap between vaccination intention and behavior among young women in China.
