The impact of mental distress on influenza vaccine coverage

Influenza is a major cause of morbidity and mortality worldwide. The flu vaccine is the most important strategy to prevent influenza. Studies indicate that individuals with mental health disorders are at an increased risk of comorbid health conditions that predispose them to severe flu complications. This study examined the association between mental distress and influenza vaccine coverage among non-institutionalized adults in the United States. Data was analyzed from the 2016 Behavioral Risk Factor Surveillance System (BRFSS). The analytic sample (453,924) included those with valid information on health-related quality of life (HRQOL) and flu vaccine coverage. Bivariate analysis and logistic regression were performed. Those with infrequent mental distress had 1% (95% confidence interval [CI] 0.96,1.03) lower odds and those with frequent mental distress had 21% (95% CI 0.75,0.82) decrease odds of receiving the flu shot in comparison to those with no mental distress, given all else equal. A negative effect on influenza vaccination rates was observed with frequent mental distress when compared to those with no mental distress. Further studies are warranted to better understand this association.
