The metabolic syndrome in South Asians: continuing escalation & possible solutions.
The metabolic syndrome is a crucial factor in causation of type 2 diabetes mellitus (T2DM) and coronary heart disease (CHD) in South Asians. Approximately 20-25 per cent of urban South Asians have evidence of the metabolic syndrome. Furthermore, insulin resistance was reported to be present in nearly 30 per cent of children and adolescents in India, more so in girls. At the same time many young individuals have clustering of other risk factors/conditions related to insulin resistance (e.g., non-alcoholic fatty liver disease, obstructive sleep apnoea, etc.). Rapid nutritional and lifestyle transition in urbanized areas in various countries in South Asia are prime reasons for increasing prevalence of obesity and the metabolic syndrome. It is particularly important to effectively implement and strengthen population-based primary prevention strategies for the prevention of 'epidemic' of obesity and the metabolic syndrome. The lifestyle factor modification to prevent the metabolic syndrome and T2DM in South Asians should start in early childhood. Finally, there is an urgent need to conduct research studies regarding the correct definitions of the metabolic syndrome and genetic and perinatal factors related to insulin resistance in South Asians.
