Spatial risk of tuberculosis mortality and social vulnerability in Northeast Brazil

Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

INTRODUCTION:

Tuberculosis (TB) is the most common infectious disease in the world. We aimed to analyze the spatial risk of tuberculosis mortality and to verify associations in high-risk areas with social vulnerability.

METHODS:

This was an ecological study. The scan statistic was used to detect areas at risk, and the Bivariate Moran Index was used to verify relationships between variables.

RESULTS:

High-risk areas of tuberculosis mortality were statistically significantly associated with domain 2 of the Social Vulnerability Index (I=0.010; p=0.001).

CONCLUSIONS:

This study provides evidence regarding areas with high risk and that vulnerability is a determinant of TB mortality.

Keywords:
