Background: Type 1 diabetes mellitus (T1DM) is an autoimmune condition, characterized by the destruction of pancreatic beta cells, resulting in lifelong dependency on insulin. It is a significant health burden in adolescents and young adults, with long-term complications affecting quality of life and survival. We aim to explore sex-stratified trends in mortality and disability-adjusted life years (DALYs) due to T1DM from 1990 to 2021. Methods: We obtained sex-stratified data for adolescents and young adults (15-39 years) with T1DM from the Global Burden of Disease (GBD) from 1990 to 2021. The mortality rates were age-standardized and expressed per 100,000 deaths. Trends were analyzed as annual percentage change (APC) and average APC (AAPC) using Joinpoint Regression. Results: From 1990 to 2021, deaths due to T1DM in adolescent and young adult males increased globally from 7,123 to 9,244 per annum, with age-standardized mortality rates (ASMRs) decreasing from 0.64 to 0.61 and standardized DALYs rising from 49.56 to 51. In females, deaths rose from 6,160 to 6,892, with ASMRs declining from 0.57 to 0.47 and DALYs declining from 47.12 to 43.11. Despite the apparent rise in deaths, ASMRs exhibited a significant decline in both sexes, with an AAPC of -0.16% (95% CI: -0.20 to -0.12) in males and -0.62% (-0.68 to -0.55) in females, four times that of in males. The DALYs showed a significant decline in females with an AAPC of -0.31% (-0.35 to -0.26) but a significant increase in males with an AAPC of 0.09% (0.04 to 0.12). Males showed the greatest APC increase in ASMRs of 1.34% from 1990 to 1994, while females showed the greatest APC increase of 0.45% from 1990 to 2000, three times less and over twice the period seen in males. This was followed by the greatest APC decline of -1.14% in females from 2001 to 2011, and a non-significant decline of -0.14% till 2021. Males experienced the greatest decline of -1.14% from 2000 to 2013. It then increased significantly from 2013 to 2018 (APC: 0.73%), followed by a significant decline of -0.62% till 2021, almost four times that in females. DALYs showed a similar trend in females with the greatest increase of 0.45% from 1990 to 2000, followed by the greatest decrease of -1.14% till 2011, and then a non-significant decline of -0.14 till 2021. Males showed the greatest increase of 1.24% from 1990 to 1994 and the greatest decrease of 0.63% from 2000 to 2013, followed by a much smaller decline. Conclusion: Although ASMRs declined, the recent decline in ASMRs in females is becoming less pronounced highlighting the importance of ongoing monitoring and improvement strategies. The disparity in DALYs between males and females also demands the need for targeted interventions addressing male-specific challenges to reduce the burden of T1DM.
