Individuals diagnosed with prediabetes can reduce their long-term risk of death and diabetes-related health complications if they delay the onset of diabetes for just four years through diet and exercise. Guangwei Li of the China-Japan Friendship Hospital and colleagues report these findings in a study published July 9 in the open-access journal PLOS Medicine . Type 2 diabetes is associated with an increased risk of death and disability, and imposes a significant economic burden on individuals and societies worldwide.
Lifestyle changes, such as eating a healthy diet and getting more exercise, can delay or reduce the risk of developing diabetes in people diagnosed with impaired glucose tolerance (IGT)—commonly called prediabetes. However, it is unknown how long a person must delay diabetes to ensure better long-term health. In the new study, researchers looked at health outcomes from 540 prediabetic individuals who participated in the original Da Qing Diabetes Prevention Study, a six-year trial conducted in Da Qing City in China, starting in 1986.
Participants belonged to either a control group or one of three lifestyle intervention groups, which involved following a healthy diet , getting more exercise, or both. The trial followed up with participants for more than 30 years. Li's team determined the long-term risk of death, cardiovascular events —like heart attack , stroke or heart failure —and other diabetes-related complications for trial participants.
They found that.
