Weight loss alone `doesn’t lower heart disease risk in diabetics`
Washington: An intensive diet and exercise program resulting in weight loss does not reduce the risk of cardiovascular events such as heart attack and stroke in people with longstanding type 2 diabetes, US researchers say.
Researchers at 16 centers across the United States worked with 5,145 people, with half randomly assigned to receive an intensive lifestyle intervention and the other half to a general program of diabetes support and education.
Both groups received routine medical care from their own health care providers.
Although the intervention did not reduce cardiovascular events, the study showed other important health benefits of the lifestyle intervention, including decreasing sleep apnea, reducing the need for diabetes medications, helping to maintain physical mobility, and improving quality of life.
"People who are obese and have type 2 diabetes can lose weight and maintain their weight loss with a lifestyle intervention," said Dr. Rena Wing, a professor of psychiatry and human behavior at Brown University in Providence.
"Although the study found weight loss had many positive health benefits for people with type 2 diabetes, the weight loss did not reduce the number of cardiovascular events,” she added.
