Objective: Completion of human papillomavirus (HPV) vaccine series among Texas Hispanic adolescents is low compared to national data. We examined the association between HPV vaccine initiation and completion among Hispanic adolescents in a rural, Texas-Mexico border county and specific individual and neighborhood-level characteristics.
Design: Cross-sectional analysis of data from a broader cancer prevention program.
Setting: Underserved colonias communities in a Texas-Mexico border county.
Participants: Hispanic mothers or caregivers (n=712) and adolescents aged 11-17 years (n=1120) linked to publicly available data about their neighborhood.
Main outcome measures: HPV vaccine adherence (ie, initiation and completion) as reported in either the Texas Immunization Registry or adolescents' electronic medical records, measured at the end of the cancer prevention program.
Methods: Logit and multi-level mixed-effects logistic regression of individual- and neighborhood-level data.
Results: Factors associated with HPV vaccine initiation and completion were female gender (P<.01), adolescent insurance status (P<.001), and receipt of required vaccines (P<.001). After controlling for neighborhood-level characteristics, only receipt of required vaccines remained significant.
Conclusions: Findings indicate a relationship between Hispanic adolescents' receiving the required vaccine series for school admission and HPV vaccine initiation and completion. In resource-limited settings like federally qualified health centers, further efforts should focus on implementing best practices at both the provider level (eg, education on bundled vaccine recommendation) and practice-level (eg, outreach and support by trained immunization navigators).
