Racial, Ethnic, and Geographic Disparities in Digestive Diseases Mortality in the United States, 2000-2019

Background and aims: The global burden of digestive diseases mortality has been increasing over the last 3 decades. However, little is known about disparities in digestive diseases-specific mortality in the United States. This study aimed to examine racial, ethnic, and state- and county-level disparities in digestive diseases mortality rate in the United States between 2000 and 2019.

Methods: We used the Institute of Health Metrics and Evaluation Global Health Data Exchange to gather digestive diseases age-standardized mortality rates for 5 racial and ethnic groups (White, Black, Latino, American Indian/Alaska Native [AI/AN], and Asian/Pacific Islander [API]) by sex, state, and county between 2000 and 2019. We used joinpoint regression analysis to evaluate the overall temporal trends by demography.

Results: The overall cause-specific mortality rate decreased from 36.0 to 34.5 deaths per 100,000 population across all groups (2000-2019). In 2019, AI/AN individuals had the highest mortality rate (86.2), followed by White (35.5), Latino and Black (both at 33.6), and API (15.6) individuals. Significant increases occurred across some of the racial and ethnic groups, with an increased average annual percentage change for 2000-2019 among AI/AN (0.87%; 95% confidence interval, 0.77%-0.97%) and White individuals (0.12%; 95% confidence interval, 0.02%-0.22%) particularly among females, while Latino, Black, and API individuals showed reduced average annual percentage change for 2000-2019. AI/AN constitutes the main race affected in the top 10 counties. Substantial state-level variation emerged, with the highest mortality rates in 2019 seen in West Virginia.

Conclusions: Despite an overall decrease in digestive diseases mortality, significant disparities persist across racial and ethnic groups. AI/AN and White individuals experienced increased mortality rates, particularly among females. Targeted interventions and further research are needed to address these disparities and improve digestive health equity.
