BACURAU, Aldiane Gomes de Macedo  e  FRANCISCO, Priscila Maria Stolses Bergamo. Prevalence of influenza vaccination in adults and elderly with chronic respiratory diseases. Cad. Saúde Pública [online]. 2018, vol.34, n.5, e00194717.  Epub 28-Maio-2018. ISSN 0102-311X.  https://doi.org/10.1590/0102-311x00194717.

The objective was to estimate the prevalence of influenza vaccination in adults and elderly with chronic respiratory diseases (CRDs). The sample included individuals 20 to 59 years of age (n = 23,329) and ≥ 60 years (n = 9,019) that participated in the Brazilian National Survey on Access, Utilization, and Promotion of Rational Use of Medicines (PNAUM) in 2013-2014. We estimated influenza vaccination prevalence rates and respective 95% confidence intervals (95%CI). Associations were verified with the Rao-Scott chi-square test, with significance set at 5%. For all adults and elderly with CRD, prevalence of vaccination was 42.1% (95%CI: 37.2-47.1), with a statistically difference between the two age groups (p < 0.001). The adult population showed significant differences according to marital status (p < 0.05), and the elderly population showed higher vaccination prevalence in the South of Brazil compared to the Northeast (p < 0.05). For the sample as a whole, chronic bronchitis was the most frequently reported disease (43.5%). Considering each specific disease, the percentage of vaccinated adults was low, varying from 25% (other respiratory diseases) to 42% (chronic bronchitis), without a statistically significant difference (p = 0.330). Individuals with respiratory diseases and the elderly in general (≥ 60 years) are priority groups for influenza vaccination; in general, in all the subgroups, prevalence rates were below the target set by the Brazilian Ministry of Health. The recommendation that the vaccine should be applied by a health professional may explain this low adherence to vaccination by the elderly.
