Socioeconomic determinants of influenza vaccination among older adults in Italy

Research output: Contribution to journalLetter


Objectives: Seasonal influenza represents a major threat to public health but vaccination campaigns are strongly recommended to reduce the risks of serious complications and mortality among community-dwelling elderly persons. We investigated on potential social predictors of influenza vaccination among older adults in Italy. Methods: Data analysis was based on the national survey "Health and use of health care," which was carried out in 2004/2005 and reached a sample of 25,183 elderly persons. After initial univariate and bivariate statistics, we used multivariate logistic regression to evaluate potential independent predictors of influenza immunization. Results: 62.6% of the recruited subjects declared to be vaccinated against influenza. At bivariate analysis, significative differences in immunization rates arose by each socioeconomic variable investigated. Logistic regressions confirmed that individuals in lower social classes have higher chances of being vaccinated. Moreover, older age and chronic disease were associated with higher likelihood of immunization. Conversely, reporting good health predicted a lower uptake. Conclusion: In our analysis we found several independent predictors of influenza vaccination. Surprisingly, individuals belonging to lower social classes have higher chances of being vaccinated. These results suggest that vaccination policies have a positive effect in preventing socioeconomic inequalities in access to this service in Italy.
