Abstract
BACKGROUND: Annual influenza vaccination has been recommended for all adults since 2010. This study aimed to identify characteristics associated with influenza vaccination among adults. METHODS: Data from the National Health Interview Survey from 2011 to 2016 were analyzed. RESULTS: Influenza vaccination coverage among adults increased from 38.28% in 2011 to 44.75% in 2016 (1.50% per year on average). In multivariate analysis, the largest magnitude of association was found with pneumococcal vaccine (lowest and highest odds ratios from 2011 to 2016: 3.37-3.78), followed by physician visits ≥4 in the past 12 months (2.33-3.03), age ≥65 years (1.69-2.07), having a usual place for sick care (1.41-1.94), insurance coverage (1.52-1.79), hepatitis B vaccine (1.48-1.71), ratio of family income to the poverty threshold ≥4 (1.19-1.54), race of Asian (1.24-1.47), number of years on the job ≥21 (1.21-1.41), class of worker (Federal government: 1.23-1.32, State government: 1.15-1.38), high-risk conditions (1.13-1.26), physical activity ≥5 times/week (1.11-1.25) and being female (1.13-1.20). However, adults living in West, and adults of Black/African American, never married, high school education, self-employed and current smokers had lower vaccine uptake. CONCLUSIONS: Several characteristics were identified to be associated with influenza vaccination uptake, which could be useful for targeted efforts to improve influenza vaccination coverage among adults.
