| Summary: | Type 2 diabetes (T2D) is a rapidly growing global health concern, projected to affect 1.3 billion people by 2050, necessitating a multidisciplinary approach. This review examines the epidemiological disparities in T2D, focusing on modifiable and nonmodifiable risk factors, socioeconomic determinants, and healthcare inequities. While genetic predisposition, age, and ethnicity contribute to T2D risk, socioeconomic status (SES) significantly mediates modifiable factors such as diet, physical activity, and access to healthcare. Lower SES is associated with poorer lifestyle choices, limited access to resources, and increased exposure to risk factors, exacerbating T2D prevalence among vulnerable populations. Geographic variations in T2D prevalence are evident, with racial and ethnic minorities and lower-income individuals being disproportionately affected in regions like the United States and Europe. The economic burden of T2D is substantial, with global healthcare expenditures reaching USD 966 billion in 2021 and projected to rise significantly, albeit with variations across different countries and health systems. Despite advancements in treatment, inequities in healthcare access persist, particularly in low- and middle-income countries, hindering optimal glycemic control and consequently contributing to preventable complications and poor health outcomes. This review highlights the critical need for targeted interventions and policy reforms to address the intersection of demographic, economic, and healthcare-related variables influencing T2D disparities. By bridging gaps in prevention, management, and treatment and accounting for the effect of SES on both modifiable and nonmodifiable risk factors, the global disease burden of T2D could be reduced and health equity could be improved. |
