Objective: Adolescent females' HPV vaccine completion in the U.S. is low. More recent research is needed to investigate factors that relate to HPV vaccine completion among female adolescents in the United States.
Methods: Provider-validated data from the 2012 National Immunization Survey-Teen for females ages 13-17 years (N = 9058) were analyzed from February-May 2014 using survey sample weighted statistics. A multivariable Poisson regression estimated prevalence ratios (PR) for factors influencing HPV vaccine completion: mother's education, poverty status, adolescent's grade, facility type, and receipt of other adolescent vaccinations.
Results: In multivariable models, 9-12th grade daughters were more likely to complete HPV vaccination than 6-8th grade daughters (PR = 1.81, 95% CI = 1.58-2.06). Those seen in hospital facilities completed HPV vaccination 1.3 times more (PR = 1.29, 95% CI = 1.02-1.62) and those seen in private facilities were 1.2 times more likely to complete (PR = 1.22, 95% CI = 1.01-1.48), than those seen in public facilities, respectively. Compared to those without recommended adolescent vaccinations, receipt of seasonal influenza vaccination related to HPV vaccine completion (PR = 1.71, 95% CI = 1.54-1.89), as did receipt of TDAP vaccination (PR = 1.17, 95% CI = 1.03-1.33) and Meningitis vaccination (PR = 2.74, 95% CI = 2.20-3.42).
Conclusions: Adolescent females in high school, seen in private/hospital facilities, and up to date on other recommended adolescent vaccinations are most likely to complete the HPV vaccine.
