Comparing Human Papillomavirus Vaccine Initiation in Georgia to Regional and National Estimates: Results from the National Immunization Survey – Teen, 2014 - 2016 Público

Abstract

Objective: To assess the coverage of HPV vaccine series initiation among adolescents living in Georgia and to investigate the extent of Georgia-specific predictors of HPV vaccine initiation relative to the regional and national estimates.

Methods: Data were merged and analyzed from the NIS-Teen from 2014 through 2016. Study participants, aged 13 to 17 years, with adequate provider-verified immunization data from all 50 states and Washington, D.C. (N=64,151) were included in the analysis. Subsets of the data were created for HHS Region 4 states (N=8,446) and the state of Georgia (N=1,114) for geographical comparisons. The outcome of interest was HPV vaccine initiation status (≥1 doses versus 0 doses of HPV vaccine). Poisson regression was used to evaluate significant predictors of the outcome of interest within the three populations: Georgia, HHS Region 4 and the United States.

Results: Approximately half of adolescents in all compared geographies initiated HPV vaccination (Georgia: 56%, CI: 54.0-61.5; National: 56%, CI: 55.0 – 56.5; HHS Region 4: 52%, CI 50.0 – 53.1). Female adolescents in Georgia were more likely to be vaccinated (66%) compared to male adolescents (50%) (PR: 1.19, CI: 1.02 - 1.41) and provider recommendation was strongest for males (Georgia Males: aPR=2.49, CI=1.74, 3.56; Georgia Females: aPR=1.60, CI=1.23, 2.07).

Conclusions: Provider recommendation for HPV vaccine initiation was the strongest predictor for both male and female adolescents across the three study populations. Although Georgia generally followed patterns of initiation seen in HHS Region 4 and in the U.S., deviations did occur in certain demographic groups. These findings support the need for further investigations into state-level predictors of low HPV vaccine uptake, and preliminarily suggest a need for Georgia-based HPV vaccine interventions targeted towards specific subgroups.
