BY NICHOLAS BAKALAR: The study, in Pediatrics, found that the less sleep, the more likely the children were to have higher body mass indexes, higher insulin resistance and higher glucose readings. All three are risk factors for Type 2 diabetes.
Over all, increasing weekday sleep duration by an hour was associated with a 0.2 lower B.M.I. and a 3 percent reduction in insulin resistance. The reasons for the link remain unclear, but the researchers suggest that poor sleep may affect appetite regulation, leading to overeating and obesity. This observational study could not establish cause and effect. (read more)
BY MARK SCHREINER: According to the latest figures from the Centers for Disease Control and Prevention, more than 29 million people in the United States have diabetes – many of them the type 2 form of the disease. That’s where the body doesn’t produce enough insulin on its own.
But another 86 million adults have prediabetes, with up to a third at risk of developing type 2 diabetes within five years.
Now while experts say a change in lifestyle, with a healthier diet and more exercise, would cut that number down, so could an inexpensive, generic prescription drug called metformin – a drug that is currently being used by only 0.7 percent of patients with prediabetes. (read more)
BY AMBER COX: Adults who underwent bariatric surgery and were in type 2 diabetes remission demonstrated high glycemic variability and oxidative stress, according to findings published in Nutrition, Metabolism & Cardiovascular Diseases.
Brunella Capaldo, MD, of the department of clinical medicine and surgery at Federico II University in Naples, Italy, and colleagues evaluated 22 adults (10 men; mean age, 50 years; mean BMI, 31 kg/m2) who were in remission of type 2 diabetes after bariatric surgery and 22 age-, sex- and BMI-matched controls to assess glycemic variability and oxidative stress. Mean postoperative follow-up was 4 years. Among the bariatric surgery group, 11 underwent Roux-en-Y gastric bypass (RYGB) and 11 underwent sleeve gastrectomy. (read more)
