Plain language summary
Obesity is a metabolic risk factor for Type 2 diabetes (T2D) and cardiovascular diseases(CVD). This study was carried out to measure the effectiveness of lifestyle interventions on cardiovascular morbidity and mortality. 5145 overweight and obese patients with T2D were randomised assigned in groups with lifestyle interventions of weight loss through exercise and reduced calorie intake. The control group were given diabetes support and education. The data from this study suggest that lifestyle interventions were effective in weight loss and management of the CVD. However reducing the risk of CVD in comparison to the control group was not determined.
Abstract
Look AHEAD (Action for Health in Diabetes) was a randomized controlled trial that examined the impact of long-term participation in an intensive weight loss intervention on cardiovascular disease (CVD) morbidity and mortality in people with type 2 diabetes (T2D). The results from this trial suggest that intensive lifestyle interventions are effective in helping patients to achieve management of cardiovascular risk factors and reducing the need to initiate medication usage to manage these conditions, though the benefits in terms of the prevention of CVD morbidity and mortality beyond those achieved through aggressive medical management of hypertension and dyslipidemia is not clear. Additional benefits of participation in an intensive lifestyle intervention such as lowered chronic kidney disease risk, blood pressure, medication usage, improved sleep apnea, and partial remission of diabetes are discussed.
