Background: Thyroid disorders are common endocrine disorders including thyrotoxicosis, thyroiditis, hypothyroidism, and autoimmune thyroid diseases. Although it affects an estimated 200 million people globally, the epidemiology of this condition remains underexplored. Here we aimed to investigate mortality trends attributable to thyroid disorders in the US stratified by year, sex, race, and region. Methods: Using data from the CDC WONDER database, we calculated the crude and age-adjusted mortality rates (AAMRs) per 1,000,000 individuals (≥25 years) and used Joinpoint regression to determine annual and average annual percent change (AAPC) in the mortality trends. Results: Between 1999 and 2020, 561,089 deaths were recorded among patients with thyroid disorders in the United States, with an overall increasing trend in mortality (AAPC = 0.78). The age-adjusted mortality rate (AAMR) declined gradually from 1999 to 2018 (APC = -0.43, 95% CI: -0.65 to -0.22) before rising sharply from 2018 to 2020 (APC = 13.05, 95% CI: 6.39 to 20.12). Females had a higher AAMR (139.75) than males (81.99). Among racial and ethnic groups, Whites exhibited the highest AAMR (124.09), followed by American Indian or Alaskan Natives (121.36), Hispanics (89.13), Black or African Americans (88.44), and Asian or Pacific Islanders (59.36). Regional disparities showed the highest AAMR in the Midwest (130.45) and the lowest in the South (109.40). West Virginia (199.93) and North Dakota (198.82) reported the highest state-level AAMRs, while Nevada (60.18) and Florida (65.49) had the lowest. Non-metropolitan areas experienced higher mortality rates (141.04) than metropolitan areas (112.21), underscoring significant geographical and demographic variations in thyroid disorder-related mortality. Conclusion: Adults in the US have shown a rising trend in Thyroid-related deaths, with the highest mortality rates seen in females, Whites, and people living in the Midwest and Non-metropolitan areas. Our study also highlights the disparities across different demographics. Policy makers should focus on equitable access to healthcare to control this increasing mortality.
