They found that the more African-origin markers in children’s genetic makeup, the less their bodies responded to insulin-and the more insulin in their blood.
Elderly men and women with normal body weight still may be at risk for developing type 2 diabetes if they have large amounts of muscle fat or visceral abdominal fat, according to a University of Pittsburgh study published in the February issue of the journal Diabetes Care. “Our study found that, even though an elderly person may not be overweight, he or she might still be at risk for developing diabetes,” said Bret H. Goodpaster, Ph.D., of the University of Pittsburgh division of endocrinology and metabolism and principal investigator of the study. “An important factor is where in the body their excess fat is stored.”
