Abstract
BACKGROUND: The prevalence of type 2 diabetes (T2D) and obesity are increasing in the United States. However, population-level data for mortality trends due to T2D and obesity are limited. This study aims to assess these death trends among adults in the United States categorized by sex, race, and geographical location. METHODS: We queried the CDC-WONDER database for multiple cause of death data of adults aged ≥25 years. The crude mortality rates (CMR), age-adjusted mortality rates (AAMRs), annual percent change (APC), and the average APC (AAPC) along with a 95% confidence interval (CI) were analyzed. RESULTS: From 1999 to 2022, a total of 88,597 T2DM and obesity-related deaths were recorded in the United States. The AAMR consistently increased from 1999 to 2017 (APC: 7.64; 95% CI: 1.91-9.96), followed by a marked rise from 2017 to 2022 (APC: 20.13; 95% CI: 12.88-38.57). The AAMR was approximately 3.58 times higher during the COVID-19 pandemic compared to the period from 1999 to 2019. The AAMR for males was consistently greater than that for females. The highest AAMR was observed in non-Hispanic (NH) Blacks or African Americans, followed by NH White, Hispanic or Latino, and other NH populations. Rural areas (AAMR: 1.86, 95% CI: 1.83-1.89) exhibited a greater AAMR than urban regions 1.26 (95% CI: 1.25-1.27). CONCLUSIONS: Our results indicate a substantial increasing trend of T2D and obesity-related deaths in the United States especially during the COVID-19 pandemic.
