The Uptake of Human Papillomavirus Vaccination and Its Associated Factors Among Adolescents: A Systematic Review.

BACKGROUND: The purpose of this review was to explore the uptake of the human papillomavirus (HPV) vaccination, its associated factors, and the facilitators of and barriers to HPV vaccination among adolescents.

METHODS: A comprehensive literature search was conducted through 5 electronic databases, including PubMed, CINAHL, Cochrane Library, Medline, and PsycInfo from January 2006 to March 2015 for studies examining the uptake, awareness, knowledge, acceptability, and intention of adolescents with regard to HPV vaccination.

RESULTS: Twenty-eight studies were identified and included. The HPV vaccination uptake rate (at least 1 dose) varied significantly among countries, ranging from 2.4% to 94.4%. Scotland achieved the highest uptake of all the studies included in this review, while Hong Kong had the lowest, at 2.4% to 9.1%. This review also showed that adolescents had limited awareness and knowledge of HPV infections and vaccines, even 10 years after the vaccine had become available.

CONCLUSIONS: It is recommended that barriers to the uptake of the vaccine should be addressed, and that school-based sexual health education of HPV infection and vaccine promotion should be reinforced.
