Abstract

Background
Many studies have shown that self-reported health status is related to current health status and various health-related factors. However, few studies have examined the association between self-reported health status and health promotion activities. Thus, this study was conducted to assess the association between self-reported health status and influenza vaccination.
Methods
In total, 9,825 adults aged 19 years or older who responded to the influenza vaccination questionnaire as part of the 6th Korean National Health and Nutrition Examination Survey (KNHANES, 2014–2015) were included. Related factors were grouped into three categories: socioeconomic, medical, and health related. Univariate analysis was performed to investigate the relationship between influenza vaccination and each variable. Multivariate analysis was conducted by adjusting variables that were statistically significant in the univariate analysis.
Results
Multivariate analysis showed that the influenza vaccination rates were significantly lower in men, medium-highest income level earners, current smokers, and high-risk drinkers (P<0.05). In women, elementary school or lower education level, being married, and having a comorbidity were associated with higher vaccination rates (P<0.05). Although in all the subjects, influenza vaccination rate decreased with better self-reported health status, the association was not statistically significant (odds ratio [OR], 0.844; 95% confidence interval [CI], 0.711–1.002). However, subgroup analysis with respect to sex revealed that in women, better self-reported health status was associated with a lower likelihood of having an influenza vaccination (OR, 0.759; 95% CI, 0.606–0.950).
Conclusion
Better self-reported health status may be associated with lower influenza vaccination rates. There is a need for a strategy to increase the influenza vaccination rate among people with good self-reported health status.
