In addition,
South Asians tend to gain weight in the abdominal region (Waist: hip ratio >1.0 in men, >0.9 in women) and are at greater risk of heart disease.
Environmental factor like low birth weight, malnutrition also possibly predisposes Indians to increased risk of diabetes and heart attacks in adulthood.
Statistics suggest that
South Asians seem more naturally vulnerable to heart disease than other ethnic groups. Lancet 2000 study showed that, even after adjusting for all known risk factors; South Asians in Canada appeared to have a higher rate of heart disease than Europeans or Chinese living there. Some doctors think that this vulnerability can be explained by the "thrifty-gene" theory, which holds that South Asians adapted over many generations to the region's frequent famines. Now with a very recent overabundance of food, their bodies are having difficulty making a metabolic U-turn and the result is high insulin intolerance, with accompanying raised levels of diabetes and obesity.
