Temporal trend of the incidence of TB/HIV coinfection and HIV testing of the old Brazilian population from 2008 to 2018

Abstract Objective Analyze the temporal trend of the incidence of TB/HIV coinfection and the ratio of HIV testing in the Brazilian old population and its regions from 2008 to 2018. Method Ecological, time-series study carried out with all new cases of old people with TB/HIV coinfection. The data were extracted from SINAN-TB and analyzed using the Prais-Winstenmethod. Results In the temporal analysis of the incidence, Brazil showed a stable trend (VPA 2.1), and regarding the regions: Southeast, decreasing trend (VPA -2.15); Northeast and North, increasing trends (VPA 9.92; VPA 10.18, respectively); and South and Midwest, stable trends (VPA 0.17; VPA 4.81, respectively). In Brazil and its regions, the ratio of HIV testing showed growing trends: Brazil (VPA 12.82), North (VPA 20.46), Northeast (VPA 17.85), Southeast (VPA 10.29), South (VPA 7.11), and Midwest (VPA 6.10). Of the 3213 new cases of TB/HIV coinfection reported during the study period, most (68.66%) were male, 78.74% in the age group from 60 to 69. As for the clinical form, the majority (72.70%) was of the pulmonary type. Conclusion Given the magnitude and implications of TB/HIV coinfection in the old population for health care services, these findings may support health professionals and managers in adopting effective measures to control these diseases.
