Weight gain after age 50 and the risk of diabetes

Gaining weight after age 50, especially around the waist, increases the risk of type 2 diabetes, as per a study published in the June 23-30 issue of JAMA.

After analyzing data from the Cardiovascular Health Study conducted from 1989 to 2007, the study reviewed information on more than 4,000 people over the age of 65 and found that compared to people whose weight remained stable after age 50, those who gained the most weight after 50 (more than 20 pounds) nearly tripled their risk of developing type 2 diabetes.

The magnitude of the increased risk associated with various measures appeared to decline with age, with about half the risk in individuals aged 75 years and older compared with those aged 65 to 74 years. However, the interaction with age was significant only for BMI at age 50 and at baseline and for fat mass.  (AMA News, input from Dr Brahm Vasudeva)
