South Asians Have Higher Diabetes Risk

A Canadian study published in the Journal of Clinical Endocrinology and Metabolism reported that South Asians are more vulnerable to having a higher fat mass and a lower lean body mass, and therefore, are more prone to developing insulin resistance and diabetes.

Dr. Scott Lear from Fraser University in Burnaby, British Columbia, and his colleagues compared the ratio between total body fat  and lean body mass in 196 Aboriginal, 222 Chinese, 202 European, and 208 South Asian adults and examined how differences in the ratio of total body fat to lean mass might be related to insulin resistance.

“We demonstrated that differences in total body fat to lean body mass ratios among the ethnic groups accounted for the substantial variation in insulin levels and insulin resistance,” the authors reported.  “Importantly, higher levels of insulin and homeostatis model assessment in the South Asian men and women could largely be attributed to higher total body to lean body mass ratios.”

“Interventions that reduce fat mass and increase muscle mass, such as caloric restriction and regular exercise, should be investigated in this population,” the authors concluded.
