Spatial analysis of social inequities and mortality from tuberculosis: an ecological study

Ana Angélica Rêgo de Queiroz, Ricardo Alexandre Arcêncio


Aim: to analyze the spatial and spatial-temporal distribution of tuberculosis deaths and their relation to indicators of social inequity. Method: ecological study to be carried out in Natal-RN. All cases of death that have tuberculosis as the underlying or associated cause, registered in the Mortality Information System, will be considered in the period 2008-2014. An exploratory analysis of sociodemographic and operational variables will be performed. Data from the 2010 Demographic Census will be used to formulate social indicators through analysis of key components. The scan statistic will be used to identify clusters of risk. The relationship between death and social inequity will be verified through multiple linear and spatial regression and residue investigation to evaluate spatial dependence through the application of the Moran Global I Test. Expected results: Mortality due to tuberculosis is not randomly distributed in the municipality, and is more frequent in groups with greater social inequity.
