INCIDENCE OF PULMONARY TUBERCULOSIS AND SOCIOECONOMIC CONDITIONS IN THE STATES OF THE SOUTHEAST REGION OF BRAZIL
Keywords: Pulmonary tuberculosis. Social determinants. Spatial analysis.
Objective: to analyze the spatial autocorrelation between incidence of pulmonary TB, Human Development Index (HDI), Gini Index (GI) and other socioeconomic indicators in southeastern Brazil. Methodology: This is an ecological analytical study mixed with time series and spatial aggregation with the municipalities (unit of analysis) of the states of southeastern Brazil that covered the period 2010-2019, which in turn was subdivided into two others: 2010-2014 and 2015-2019. Spatial smoothing methods were used for estimating TB incidence, Moran's Global Index and Univariate and bivariate Local Indicator of Spatial Association (LISA) with the construction of thematic maps for analysis of results. Results: With a confidence level of 99%, the bivariate LISA showed positive autocorrelation with Moran's Index (I) = 0.349 for HDI, I = 0.266 for income, I = 0.323 for education (complete high school) and weak correlation with I = 0.093 for intra-household agglomeration. There was a weaker negative autocorrelation for GA (I = 0.144), infant mortality (I = 0.182), Theil-L index (I = 0.156) and proportion of extremely poor (I = 0.125). Higher incidence of pulmonary TB was auto-correlated to better human development conditions and income and more weakly to intra-household overcrowding, less inequality, lower infant mortality and proportion of extremely poor people. Conclusion: There was an association between a higher incidence of pulmonary TB and better conditions for human development and intra-household overcrowding.
