Women’s Midlife Weight Key to Future Diabetes Risk
People Marrying excess weight who aim to ward off diabetes should try to lose the pounds before they reach middle age, Australian researchers suggest.
BODY MASS INDEX Strong Predictor for Diabetes Risk
A woman’s body mass index (BMI) in her late 40s was the strongest predictor of her risk of developing diabetes over the next eight years, Dr. Gita D. Mishra of the University of Queensland and her colleagues found.
On the other hand, there was no link between weight change in subsequent years and the likelihood of becoming diabetic.
Is Your Weight The Problem?
While excess weight is understood to boost the risk of developing type 2 diabetes, the effects of shorter-term weight gain or loss are not as clear, Mishra and her team note in the journal Diabetes Care. To investigate, the researchers followed 7,239 women for 8 years. Study participants were 45 to 50 years old when the study began, and they completed surveys on their health at the study’s outset in 1996 and in 1998, 2001 and 2004.
Your greatest risk.
Those with BMIs of 25 or greater, indicating they were overweight or obese, in 1996 were at the highest risk of developing type 2 diabetes by 2004, the researchers found. Very obese women with BMIs of 35 or above were 12 times more likely than their normal-weight peers to become diabetic.
