PURPOSE: To determine epidemiological features and composition of deaths from respiratory infections in indigenous and non-indigenous people in Ecuador.

METHODS: Ecuadorian death registries from the National Institute of Statistics and Census were analyzed. Publicly available, depersonalized data from 2009 to 2011 was obtained from the REDATAM website. Respiratory Infections Death’s Estimates (RIDE) were defined from ICD-10th codes and grouped as acute upper respiratory infections (J00-J06), influenza (J09-J11), pneumonia (J12-J18), other acute lower respiratory infections (J20-J22, J40) and probable respiratory infections (R05-R07). Ethnic groups were defined as indigenous, afro-Ecuadorian, mestizo and “other” according to data available. RIDE and all-cause deaths were extracted by ethnicity and age to calculate risk ratios (RR), and age-standardized mortality rates (ASMR) were calculated for each ethnic group based on 2010 National Census.

RESULTS: From 2009 to 2011, 183,693 deaths occurred in Ecuador, from which 11,775 were identified as RIDE. The indigenous group presented a RR of 1.61 (CI95% 1.71 to 1.51; P<0.05) for RIDE. The Afro-Ecuadorian group showed a RR=0.78 (CI95% 0.88 to 0.68; P<0.05). The mestizo group presented a RR of 0.83 (CI95% 0.86 to 0.80; P<0.05), and 1.10 (CI95% 1.14 to 1.05; P<0.05) for other population. The indigenous people presented higher RR (P<0.05) at most ages, except between 30 to 39 years and beyond 90 years, in which RR was similar to other ethnic groups. The crude mortality for RIDE was 27.10 per 100000 habitants. The ASMR per 100000 habitants for indigenous, afro-Ecuadorian, mestizo and other groups were 529.03, 230.19, 623.52 and 12.57 respectively.

CONCLUSIONS: Our analysis suggests that indigenous Ecuadorian people have a higher risk of death from respiratory infections. These findings are similar to those in aboriginal groups from other regions, although predisposing genetic disparities, healthcare access and environmental factors should be addressed in further research.

CLINICAL IMPLICATIONS: Knowing the epidemiological features of deaths from respiratory infections in Ecuador is crucial for development and implementation of strategies aimed to reduce the impact of these diseases on different ethnic groups.
