Recent results from more than 11 years of follow- up in the DPPOS study have demonstrated the longer-term effectiveness of metformin, showing a 18% risk reduction for the development of diabetes, a 28% decreased risk for microvascular complications in patients who did not develop diabetes, as well as reduced risk for atherosclerosis in men.20,21 Indeed, the remarkable results of the DPP and DPPOS study call at least for a reflection about the powerful role of lifestyle modification in the prevention of diabetes and metabolic syndrome. However, we know that implementing and maintaining life style changes is difficult to say the least. Dr. Horton shared some of the approaches used in the DPP to give an idea of what it takes to achieve and sustain meaningful lifestyle changes: “All the participants across different centers in the DPP program had a very intense course in lifestyle modification. Besides physicians, we had trained dietitians, exercise physiologists, behavior modification specialists to deal with some of the psychological problems, and we used the team approach to really work with people to help them achieve the lifestyle changes.” Although most clinical practices do not have the resources to address all these factors, they should be at least be encouraging lifestyle changes or refer eligible patients to lifestyle specialists, nutritionists, or to a local DPP program in order to better address the rising impacts of type 2 diabetes and metabolic syndrome.
