Abstract

This study evaluated influenza vaccine coverage among elderly individuals (>= 60 years) living in the city of Sao Paulo, Brazil, in 2015, and analyzed associated factors. This was a cross-sectional population-based study of data from the SABE Study (Health, Well-Being, and Aging). The dependent variable was influenza vaccination in the 12 months prior to the interview, and the independent variables were sociodemographic and behavioral characteristics, self-reported health status, and use of health services. Data analysis considered the complex study sample, respecting the sampling weight. Poisson's regression was used, with significance set at 5%. Vaccine coverage was 79.7% (95%CI: 76.8-825). Influenza vaccination was associated with marital status (PR single/without partner = 0.84; 95%CI: 0.77-0.93), physical activity (PR yes = 1.08; 95%CI: 1.01-1.17), and medical appointment in the previous 12 months (PR yes = 1.22; 95%CI: 1.07-1.39). There were no differences between sociodemographic strata. Influenza vaccination in the elderly had already reached the target for universal coverage in the city of Sao Paulo. The results are relevant for planning the immunization program, pointing to priority groups to motivate for vaccination and valuing interaction between the elderly and health services. (AU)
