The role of lifestyle change for prevention of cardiovascular disease in diabetes. 
The burden of cardiovascular disease (CVD) is disproportionately greater in those with diabetes than in the general population, including higher rates of hospitalization, stroke, myocardial infarction, and mortality.  Health-promoting lifestyle factors reduce both diabetes and CVD in healthy individuals; however, the efficacy of these strategies for CVD reduction in people with preexisting diabetes is unclear.  In this review, we describe the most recent evidence (2013-2014) surrounding the effects of lifestyle changes on CVD outcomes in those with diabetes, and we contextualize the evidence against a backdrop of earlier key findings.  Two major randomized controlled trials were identified, providing opposing conclusions about the role of lifestyle factors on CVD events in those with diabetes.  Other recent prospective observational analyses support associations of physical activity and reduced CVD risk in diabetes.  Limitations across studies include the use of self-report for measurement of lifestyle or lifestyle change, the length of follow-up needed to measure CVD outcomes, and the role of participants' medications on associations of lifestyle factors and CVD outcomes.  Equivocal findings from the two randomized controlled trials support the need for additional research to identify the specific lifestyle factors that reduce CVD mortality and macrovascular complications in populations with diabetes.
