Knowledge of human papillomavirus vaccination and related factors among parents of young adolescents: a nationwide survey in China.

PURPOSE: To investigate the human papillomavirus (HPV) vaccine-related knowledge and factors associated with the knowledge among parents of young adolescents in China. METHODS: The study was based on data of a survey carried out in seven geographic regions of China. Parents of students in junior middle school were surveyed during parents' meetings. RESULTS: A total of 2895 parents were included in the analyses. Of parents, 38.3% responded with "yes" to more than three of the six knowledge questions, among whom only 4.5% of them correctly answered all six questions. Social benefit programs (41.3%), doctors and/or nurses (39.7%), and newspapers and/or magazines (36.5%) were selected as the top three sources of HPV-related knowledge. Mothers, parents who work in the health care sector, and parents with a higher annual income or with vaccination experience outside the expanded program on immunization showed a better knowledge base. Parents who consented to sex education for children or showed fear of cervical cancer were likely to have more HPV-related knowledge. In particular, the knowledge level of parents with prior consultation regarding HPV vaccines was higher. CONCLUSIONS: Parents of young adolescents in China possessed a low level of HPV vaccine-related knowledge. Findings highlight the need for tailored health education through different channels to improve HPV-related knowledge among parents.
