NEW YORK--Physical activity and fitness deserve greater attention in the prevention and management of type 2 diabetes, Steven N. Blair, PED, said at a conference sponsored by the American Diabetes Association.
Recent studies from the United States and Finland documenting that intensive "lifestyle intervention" can prevent or delay the onset of type 2 diabetes have not been designed to assess which facet-diet, weight loss, or exercise--has the greatest impact.
"My bias is that it is activity and fitness, but I don't want to debate the issue. I just want it to have equal time," said Dr. Blair, president and CEO of The Cooper Institute, Dallas.
In the Aerobics Center Longitudinal Study (ACLS), a total of 25,341 men were followed for an average of 8.4 years and 7,080 women for 7.5 years following a baseline preventive medical exam that included a maximal exercise test.
Most were healthy at baseline, although 18% reported a history of one or more chronic illnesses (including diabetes) and 7% had abnormal resting or exercise electrocardiograms.
During the follow-up, 2.4% of the men and 1.3% of the women died (JAMA 276[3]:205-10, 1996).
Being in the lowest fitness tertile was a significant independent predictor of all cause mortality among both men (relative risk 1.52) and women (2.1). The only more significant risk factors in the men were smoking (1.65), abnormal ECG (1.64), and chronic illness (1.63).
