Parental perceptions of human papillomavirus vaccination in central China: the moderating role of socioeconomic factors

Abstract

ABSTRACT Background: The huge gap in adolescent human papillomavirus (HPV) uptake between China (< 2%) and developed countries (> 60%) indicates the necessity of comprehensive examination on the modifiable factors for parents’ decision-making. The present study investigated parental perceptions of HPV vaccination for children in China from a socio-economic perspective. Methods: Parents of 9-to-14-year-old adolescents who understood the HPV vaccination (n = 925) completed our questionnaire survey in Fall 2017. Based on the structural equation modeling, we examined the relationship among knowledge, awareness, and intentions of 20 items by 7-point Likert scale, the moderating effects also were tested among 5 socioeconomic variables. Results: Parents of female students have more positive intention about the HPV vaccination than male students’ parents (3.74 vs 2.80, p < 0.001). Parents of 12–14-years old students have higher average scores in knowledge (p = 0.006) and intention (p < 0.001) than that of 9–11-years old students’ parents. The average score of mothers on knowledge (p = 0.018) and awareness (p < 0.001) was lower than that of fathers. The elder parents (≥ 50 years) performed significantly better on knowledge (p < 0.001) and awareness (p < 0.001) than the other two subgroups. Annual household income is an important factor in determining the knowledge (p = 0.0017), awareness (p < 0.001), and intention (p < 0.001). Knowledge and awareness were considered as the positive determinant of intention, and awareness was partial mediator. Child gender (P = 0.046), child age (P = 0.004), parent gender (P = 0.043) and parental age (P = 0.021) were significant moderators. Conclusion: To improve the acceptability of HPV vaccination among Chinese adolescents, policymakers should develop positive strategies for their parents.
