Researchers in this study investigated which ethnic groups were most likely to be at increased risk for diabetes due to higher total body fat and lower muscle mass. In this study, researchers measured insulin levels and compared the amount of total body fat to lean mass in 828 men and women of Aboriginal, Chinese, European and South Asian origin to determine how differences in fat mass and lean mass may be related to insulin levels and insulin resistance in each group. Of the four ethnic groups studied, South Asians were found to have both higher fat mass, lower muscle mass and greater insulin levels, placing them at increased risk for insulin resistance and diabetes. Other researchers working on the study include Simi Kohli of Simon Fraser University in British Columbia, Canada; Gregory Bondy of the University of British Columbia in Canada; Andre Tchernof of Laval University Medical Research Centre in Laval, Canada; and Allan Sniderman of McGill Health Science Centre in Montreal, Canada.
