It is a global health concern with regional variation in incidence and prevalence. This study aims to analyze the regional incidence and prevalence of T1DM among adolescents and young adults (15-39 years) from 1990 to 2021 in 26 regions. Methods: Global Burden of Disease (GBD) data for 2021 were analyzed to assess regional incidence and prevalence of T1DM among adolescents and young adults. The Annual Average Percentage Change (AAPC) was calculated to evaluate trends from 1990 to 2021, with statistical significance determined using p-values. Results: In 2021, middle socio-demographic index (SDI) has the highest incidence (54541) as well as prevalence (1.86 million), followed by Low-middle SDI (I: 48416, P: 1.80 million) and South Asia (I: 46310, P: 1.73 million). Oceania has the lowest incidence (356) as well as prevalence (12885), followed by Andean Latin America (I: 911, P: 31954) and Caribbean regions (I: 1214, P: 54610), respectively. The largest increase in AAPC of incidence was showed by Southern Latin America (2.23, CI: 2.11-2.30), High-income Asia Pacific (2.22, CI: 2.18-2.26), and Western Europe (1.80, CI: 1.73-1.84) regions, while Western Europe (1.72, CI: 1.66-1.75), Eastern Europe (1.64, CI: 1.63-1.66), and Australasia (1.38, CI: 1.36-1.40) showed largest increase in AAPC of prevalence. The Caribbean region had the greatest decline in AAPC of prevalence (-0.11, CI: -0.08 to -0.12) followed by Eastern Sub-Saharan Africa (-0.07, CI: -0.06 to -0.09) and Central Latin America (-0.04, CI: -0.02 to -0.07). There was no region with decline in incidence. All AAPC values were statistically significant (p < 0.000001). Conclusion: Middle SDI region exhibited the highest incidence and prevalence, highlighting the vulnerability of these populations, while Oceania and Andean Latin America bore the least burden. Notably, several regions, particularly in Europe, experienced substantial increases in both incidence and prevalence, emphasizing the need for targeted interventions. Conversely, some regions, such as the Caribbean, showed encouraging declines in prevalence, suggesting that effective prevention and control strategies can be implemented. These findings underscore the importance of tailored approaches to address the evolving burden of T1DM. Presentation: Saturday, July 12, 2025

Background: Bone density and structure-related disorders, such as osteoporosis and related fractures, significantly contribute to morbidity and mortality, particularly among aging populations. Monitoring temporal trends and geographic variations in mortality is essential to inform targeted public health interventions. In this study, we aimed to examine temporal and geographic variations in mortality associated with bone density and structure-related disorders in the United States from 1999 to 2022. Methods: Using ICD-10 codes M80-M85, this retrospective ecological study utilized mortality data extracted from the CDC WONDER database for the years 1999-2022. Age-adjusted mortality rates (AAMRs) were calculated and stratified by demographic variables (age, sex, and race/ethnicity) and geographic regions. Temporal trends were analyzed using Joinpoint regression to estimate annual percent changes (APCs). Geographic variations were visualized using choropleth maps, and subgroup analyses were performed to explore disparities. Statistical significance was set at p < 0.05. Results: Age-adjusted mortality rates (AAMRs) for bone density and structure-related disorders decreased overall from 1999 to 2019, with a subsequent rise observed in 2020 and 2022. Joinpoint regression revealed a significant negative trend from 2007-2016 (APC = -7.46%, p < 0.000001), followed by a positive reversal from 2019-2022 (APC = 3.78%, p = 0.013). Both males and females experienced declines in mortality, but females had a slightly higher APC of -3.10% compared to -2.82% for males. Asian/Pacific Islander groups exhibited the most pronounced decrease in mortality (APC = -11.92%, p < 0.000001) from 2009-2015, with a positive rebound in recent years. Black or African American populations had the smallest decline (APC = -1.35%). The Southern U.S. experienced the steepest decline in mortality from 2010-2016 (APC = -10.92%, p < 0.000001), followed by a strong positive trend from 2019-2022 (APC = 6.61%, p < 0.000001). Conversely, the West and Northeast regions showed milder trends with less pronounced reversals. Older age groups (65-74, 75-84) showed significant decreases in mortality, particularly the 65-74 group, which reversed to a positive trend (APC = 6.97%) from 2019-2022. The highest number of deaths occurred at the decedent’s home (3,330 in 2022). Subgroup analyses indicated significant temporal shifts in the mortality patterns across different racial/ethnic groups and geographic regions. Hispanic/Latino and Asian/Pacific Islander populations exhibited an increase in mortality rates post-2019, particularly in 2020. Conclusion: From 1999 to 2022, mortality from bone density and structure-related disorders in the U.S. exhibited significant temporal and geographic variations. These findings highlight the need for targeted public health strategies. Presentation: Monday, July 14, 2025

This study aims to examine the incidence and prevalence of T1DM by gender in the 15-39 age range between 1990 and 2021. Methods: We analyzed data from the Global Burden of Disease (GBD) to evaluate incidence and prevalence rates of T1DM in each gender from 1990 to 2021. The Annual Percentage Change (APC) and The Annual Average Percentage Change (AAPC) was used to assess trends, with p-values determining the statistical significance. Results: From 1990 to 2021, the global prevalence of T1DM was found to be increased steadily for both genders, with the highest rates recorded in 2021: 247.32 per 100,000 for females and 246.47 per 100,000 for males. Incidence rates in 2021 showed a contrasting pattern, with males exhibiting higher rates (7.18 per 100,000) compared to females (5.98 per 100,000). AAPC analysis showed that males exhibit a faster rise in both prevalence and incidence compared to females over the study period. The difference in AAPC between males and females is more pronounced for prevalence (+0.3748%) compared to incidence (+0.1956%), with all AAPC values being statistically significant (p < 0.000001). Following the APC analysis, other significant trends were revealed. Male incidence experienced the greatest increase during 2015-2021, with an APC of +1.9033% (p < 0.000001), whereas female incidence increased most between 2011 and 2014 (APC = +1.3050%; p < 0.000001). In contrast, the most significant decline in incidence was observed in females during 1990-1992, with an APC of +0.1665% (p = 0.006799), which was the lowest increase in the dataset. For prevalence, males exhibited the highest increase during 2015-2021, with an APC of +1.3938% (p < 0.000001), whereas females had their peak increase during 2006-2009, with an APC of +0.8957% (p < 0.000001). The slowest increase in prevalence for females occurred during 2014-2019, with an APC of +0.4591% (p < 0.000001). Conclusion: The prevalence and incidence of T1DM among people aged 15-39 increased significantly between 1990 and 2021, with a greater increase in males. This highlights the need for gender-specific strategies in T1DM prevention and management, and research into the factors driving these disparities. Presentation: Sunday, July 13, 2025

This condition causes significant morbidity, as measured by Disability-Adjusted Life Years (DALYs) and mortality rates, and its severity varies worldwide. The purpose of this study is to examine trends in T1DM-related death rates and DALYs across 26 geographical areas from 1990 to 2021 in order to provide a current picture of the disease's consequences and identify regional differences. Methods: This study examined DALYs and mortality rates per 100,000 people in individuals aged 15-39 years using data from the Global Burden of Disease Study from 1990 to 2021. Trends were assessed using the Average Annual Percentage Change (AAPC), with p-values used to define statistical significance. The study examined 26 regions with varied socioeconomic development indices (SDI). Using confidence intervals to account for data uncertainty, DALYs and mortality were examined to investigate the disease burden across time. Results: In 1990, the Middle SDI region had the highest DALYs at 298,352 (95% CI: 256,144 -349,670), which reached 382,857 (95% CI: 213,704-317,664) by 2021 (AAPC = 0.15, P-value < 0.000001). The region with the highest DALYs in 2021 was the Low-Middle SDI, with 419,772 (95% CI: 344,307- 495,496) cases (AAPC = -2.93, P-value = <0.000001). From 1990 to 2021, Oceania consistently had the lowest DALYs of 1,895 (95% CI: 1,264-2,577) and 4,210(95% CI: 3,011-5,724), respectively (AAPC= 0.15, P-value = 0.0004). Mortality rates in 1990 were highest in the Middle SDI area with 3,758 deaths (95% CI: 3,343-4,332) (AAPC= -1.23, P-value = <0.000001), but by 2021, South Asia had the highest mortality rate at 5,189(95% CI: 4,272-6,087) (AAPC= -0.49). Oceania had the lowest mortality rate of 25 deaths (95% CI 145-35) (AAPC = 0.193, P-value = <0.0004) in 1990, whereas Australasia had the lowest mortality rate of 28 deaths (95% CI 26-29) in 2021 (AAPC = -0.93, P-value = <0.000001). Conclusion: From 1990 to 2021, the global burden of type 1 diabetes—as indicated by DALYs and death rates—underwent a substantial shift, with significant rises in several regions. DALYs were highest in the Middle SDI region in 1990 but have migrated to the Low-Middle SDI region by 2021, reflecting shifting healthcare issues and demographics. Mortality rates followed a similar pattern, with South Asia and the Low-Middle SDI regions experiencing the highest rates in 2021. Over both time periods, however, Oceania and Australasia consistently had the lowest DALYs and death rates. These findings emphasise the critical need for targeted interventions in high-burden areas. Addressing these differences is crucial for decreasing the global burden of T1DM. Presentation: Sunday, July 13, 2025

Yet, when we examine the United States, one of the most developed nations globally, a concerning picture emerges in the realm of public health significant racial and ethnic disparities in disease outcomes. Among these, endocrine- related mortality, which includes conditions like diabetes, thyroid disorders, and hormonal imbalances, stands as a silent yet significant contributor to health inequities. Using data from the CDC WONDER database, this study seeks to explore these trends in depth, not just to identify the gaps but to shed light on the lived experiences of marginalized communities who bear the brunt of these inequities to pave the way for more equitable healthcare interventions. Methods: This descriptive study analyzes Racial and Ethnic Disparities in Endocrine-Related Mortality in the United States from 1999-2022, utilizing data from CDC Wonder database. We searched the Center for Disease Control database from 1999 to 2022 for mortality statistics with an underlying cause of death. The age-adjusted mortality rate (AAMR) was calculated per 1,000,000 deaths. We evaluated the AAMR using demographic variables such as race/ethnicity, geographic density, gender, age (25 or above), place of death, and the US Census Region. Temporal trends were assessed using Joinpoint regression software. Mortality rates by age, demographics, and place of death were examined. Statistical analysis calculated endocrine-related mortality rates and trends, with findings deemed significant at P < 0. 05. Results: Between the years 1999 to 2022, 837203 deaths were recorded to be caused by endocrine-related disorders. An overall rising mortality trend from 1999-2022 among all races and ethnicities is noted, except in Asian or Pacific Islander, Black or African American, and Hispanic patients, which shows a rise till 2020 followed by fall in age-adjusted mortality rates (AAMR) in 2022. A significant dip in mortality rate was seen in 2017 in all racial and ethnic groups. American Indian or Alaska Natives showed highest AAMR (181.87, 95% CI 178.06-185.69) followed by Black or African Americans (149.78, 95% CI 148.9-150.64), Hispanic or Latinos (112.33, 95% CI 111.59-113.07), Whites (94.31, 95% CI 66.6-68.25), Asian or Pacific Islanders (67.45, 95% CI 66.6-68.25). American Indians or Alaska Natives exhibit the steepest rise over time (APC -0.32 TO 8.85) from 1999-2022. Conclusions: Mortality due to endocrine-related disorders has dramatically increased over time. Significant disparities have been noted among different races and ethnic groups, with the highest rate among Americans and the lowest among Asians. This underscores the need for targeted interventions for specific racial groups to reduce the mortality burden of endocrine-related diseases. Presentation: Sunday, July 13, 2025

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.
