Prevention of cardiovascular disease: obesity, diabetes and the metabolic syndrome.
The current obesity pandemic is expected to result in considerable downstream morbidity, mortality and incremental costs to health care systems around the world. The major metabolic complications of obesity - type 2 diabetes and the metabolic syndrome - are predicted to be particularly burdensome. Recent randomized controlled trials have demonstrated that lifestyle interventions resulting in modest weight losses are efficacious in delaying or preventing the development of type 2 diabetes in high-risk individuals. However, on a practical level, obesity prevention strategies and programs in the 'real world' have demonstrated limited effectiveness for weight reduction. It is likely that the best that can be expected from current preventive strategies, which have largely focused on modifying individual behaviour, is the prevention of further weight gain. Environmental, social, psychological and economic drivers of the obesity epidemic have, until recently, been underappreciated and underemphasized as contributors to the current pandemic. Future efforts will need to focus on these factors and pansocietal solutions will be required if&nbsp;success in reversing the population-wide weight increases that have occurred over the past several decades is to be achieved.
