IntroductionEnglish-speaking non-Hispanic Asians (Asians) in the U.S. include populations with multiple geographic origins and ethnicities (e.g., Asian Indian, Chinese, Filipino, Japanese, Korean, and Vietnamese). Health behaviors and outcomes can differ widely among Asian ethnicities, and highlight the importance of subgroup analysis. Aggregating Asians may mask differences in influenza vaccination across various ethnicities.MethodsCombined data from 2013 to 2015 Behavioral Risk Factor Surveillance System, a population-based, telephone survey of the non-institutionalized, U.S. population aged ≥18years, were analyzed in 2017 to assess influenza vaccination among Asians. Weighted proportions were calculated. Multivariable logistic regression was used to determine independent associations between sociodemographic factors and receipt of influenza vaccination.ResultsInfluenza vaccination varied widely among Asian ethnicities, both nationally and by state. Overall, 42.1% of Asians reported having received an influenza vaccine, similar to vaccination among whites (42.4%). Coverage ranged from 36.1% among Koreans to 50.9% among Japanese. Factors independently associated with influenza vaccination among some or all Asian ethnicities included age (≥50 years), female, never married, high school or higher education, annual household income ≥$75,000, possession of medical insurance and personal healthcare provider, routine checkup in the previous year, and presence of certain chronic conditions.ConclusionsThough Asians and whites had similar overall influenza vaccination coverage, differences existed between Asian ethnicities, both nationally and by state. This information may help community-based, state-level, and national-level public health agencies to support targeted approaches for outreach to these populations, such as improving cultural and linguistic access to care, to improve influenza vaccination.Copyright © 2018 American Journal of Preventive Medicine.
