Associations between family characteristics and influenza vaccination coverage among children

Abstract

Background: To assess the associations between family characteristics and influenza vaccination coverage among children.

Methods: Data were used from the National Health Interview Survey 2011-2016.

Results: The number of children ranged from 10 720 to 12 991 per year from 2011 to 2016. After adjustment for the high-risk status of influenza complications, sex, age, region, race and office visits of children, children of adults who received influenza vaccination were 3.83-4.79 times (the lowest and the highest odds ratios from 2011 to 2016) more likely to be immunized for influenza. Health insurance (1.36-1.61) was also associated with vaccination in children. However, the education level of family adults (0.59-0.79) and marital status of being widowed/divorced/separated (0.74-0.79) were negatively associated with vaccination uptake in children. The following characteristics were not major concerns with influenza vaccination in children: class of worker, years on the job, physical activity, drinking, smoking, hepatitis B immunization, number of family members aged ≥65 years and the ratio of family income to the poverty threshold. Overall, results from the pooled analysis (2011-2016) were consistent with the above-mentioned findings.

Conclusions: Promoting parental influenza immunization and access to health insurance may be the most effective tools to promote the coverage of influenza vaccine among children.
