Review of Chinese young adults' human papillomavirus knowledge, attitudes, and vaccine acceptability.

OBJECTIVE

The human papillomavirus (HPV) vaccine is effective in reducing HPV-related disease. The 2-, 4-, and 9-valent HPV vaccines have been approved by the Chinese FDA since 2016; however, factors associated with HPV vaccine acceptability and use in Chinese young adults remain unclear.

DESIGN AND SAMPLE

We conducted a systematic review to analyze factors affecting HPV vaccine acceptability and use in Chinese young adults. A comprehensive search of databases (e.g., PubMed, CINAHL, and PsycINFO) was conducted, and articles between 2011 and 2020 were included.

RESULTS

Seventeen studies were included in the final review, and eleven were conducted in mainland China and six in Hong Kong. All studies reported low level of HPV-related knowledge. Better knowledge, more concerns about HPV-associated diseases, and being female were found associated with higher vaccine acceptability. The vaccine cost and safety were the major concerns for vaccination.

CONCLUSIONS

Findings suggested a low level of HPV-related knowledge and suboptimal vaccination rate in Chinese young adults. Theory-based interventions addressing knowledge and other influencing factors and involving both males and females are urgently needed to increase vaccine acceptability and use in Chinese young adults.
