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.
