Women with a history of gestational diabetes can mitigate their extremely high risk of developing type 2 diabetes mellitus (T2DM) with moderate-intensity exercise, found a prospective cohort study of 4554 women from the Nurses’ Health Study II (Bao W. JAMA Intern Med. 2014;174:1047-1055). The nurses, who were followed up for 16 years, reported their physical activity and sedentary behaviors on questionnaires.
“Each 5 MET-h/wk increment of total physical activity, which is equivalent to 100 minutes per week of moderate-intensity or 50 minutes per week of vigorous-intensity physical activity, was related to a 9% lower risk of T2DM,” a significant association even after adjusting for body mass index, stated the researchers. Women who engaged in 150 minutes of moderate-intensity physical activity per week had a 47% lower risk of T2DM. Walking had the same benefit as more vigorous exercise.
