Mortality from neglected tropical diseases in the state of Piauí, Northeast Brazil: temporal trend and spatial patterns, 2001-2018. / Mortalidade por doenças tropicais negligenciadas no Piauí, Nordeste do Brasil: tendência temporal e padrões espaciais, 2001-2018.

ABSTRACT

OBJETIVE To analyze temporal trends and spatial patterns of mortality due to neglected tropical diseases (NTDs) in Piauí, Brazil, 2001-2018. METHODS: This was a mixed ecological study, with risk ratio (RR) calculation, spatiotemporal trend analysis, Poisson joinpoint regression, using data from the Mortality Information System. RESULTS: There were 2,609 deaths due to NTDs in the period (4.60/100,000 inhabitants), 55.2% were due to Chagas' disease. There was a higher risk of death in male (RR=1.76; 95%CI 1.25;2.46), being aged ≥60 years (RR=40.71; 95%CI 10.01;165.53), municipalities with medium vulnerability social (RR=1.76; 95%CI 1.09;2.84), smaller population size (RR=1.99; 95%CI 1.28;3.10) and the 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 falling trend from 2009-2018. CONCLUSION: Mortality due to NTDs in Piauí remains high, particularly due to Chagas' disease, among groups with greater vulnerability, with concentration of higher rates in the southwest of the Semiarid macro-region and the northeast and south of the Cerrados macro-region.
