Mortality from neglected tropical diseases in the state of Piauí, Northeast Brazil: temporal trend and spatial patterns, 2001-2018

Abstract

Objective: To analyze temporal trends and spatial patterns of mortality from neglected tropical diseases (NTD) in Piauí, 2001-2018. Methods: Mixed ecological study, with hazard ratio (RR) calculation,spatio- temporal trend analysis, Poisson regression with inflection points, using data from the Mortality Information System. Results: There were 2,609 deaths due to NTD in the period (4.60/100,000 inhabitants), 55.2% due to Chagas disease. There was a higher risk of death in men (RR=1.76 – 95%CI 1.25;2.46), aged ≥60 years (RR=40.71 – 95%CI 10.01;165.53), municipalities with vulnerability average social (RR=1.76 – 95%CI 1.09;2.84), smaller population size (RR=1.99 – 95%CI 1.28;3.10) and Cerrados macro-region (RR=4.51-95%CI 2.51;8.11). There was an upward trend in mortality rates from 2001-2008 and a reduction from 2009- 2018. Conclusion: Mortality due to NTD in Piauí remains high, particularly due to Chagas disease, among groups with greater vulnerability, with concentration of higher rates in the southwest of the semi-arid macro-region, northeast and south of the Cerrados.
