Predictors of interest in HPV vaccination: A study of British adolescents

Human papillomavirus (HPV) vaccination is now offered to adolescent girls in the UK. Adolescents over 16 years old are likely to make their own decision about the vaccination. The purpose of this cross-sectional study was to assess acceptability of HPV vaccination among female adolescents (16 -- 19 years) and investigate socio-cultural variation in intended acceptance. Participants were recruited through two further-education colleges in England. They read information about HPV before responding to questions assessing acceptability, demographics and attitudes based on the Health Belief Model. There were 367 cases included in analyses. Most participants said they would be likely to accept HPV vaccination (89%). Ethnicity, religion and English as a first language were associated with acceptability (pseudo-R(2)=0.11). In multivariate analysis only religion remained significant, with girls from Muslim (OR=0.20, CI: 0.05 -- 0.90) or Hindu/Sikh (OR=0.09, CI: 0.01 -- 0.56) backgrounds less likely to accept vaccination. Perceived susceptibility, benefits and barriers were also associated with acceptability (pseudo-R(2)=0.25), but did not mediate the effect of the ethnicity-related variables. Interventions based on the health belief model may help encourage HPV vaccine acceptance among adolescents. Future research to understand the issues associated with HPV vaccination in different religious groups is needed.
