Diabetes in South Asians.

Area of Science:

• Public Health
• Endocrinology
• Epidemiology

Background:

• Rapid economic, dietary, and lifestyle transitions in South Asia increase vulnerability to Type 2 diabetes and cardiovascular diseases.
• Type 2 diabetes prevalence is rising across urban, semi-urban, and rural areas, affecting all socio-economic strata.
• South Asians experience earlier onset of Type 2 diabetes and more progressive complications like nephropathy compared to other populations.

Purpose of the Study:

• To identify key determinants and challenges in Type 2 diabetes prevention and management among South Asians.
• To propose pragmatic, cost-effective, and scalable translational strategies for national diabetes control programs in South Asia.

Main Methods:

• Review of recent epidemiological data on Type 2 diabetes prevalence and risk factors in South Asian populations.
• Analysis of socio-cultural, economic, and healthcare system barriers impacting diabetes care.
• Identification of priority areas for intervention, including awareness, screening, and primary care strengthening.

Main Results:

• Prime determinants include physical inactivity, imbalanced diets, abdominal obesity, and adverse early-life nutrition.
• High prevalence of pre-diabetes and undiagnosed diabetes, coupled with cultural and resource barriers, complicates management.
• Significant disparities exist in healthcare access and resource allocation for diabetes control.

Conclusions:

• Effective national diabetes control programs require tailored strategies addressing South Asian specificities.
• Focusing on awareness, vulnerable subgroups, high-risk screening, essential medicines, and primary care is vital.
• Urgent development and implementation of scalable, cost-effective interventions are needed to combat the rising diabetes burden.
