In the developed world, obesity is a serious risk factor for many chronic diseases. Besides its morbidity and mortality burden, Obesity generates a huge cost burden on countries health services. This study aims to assist policymakers in their efforts to prioritize interventions to prevent and treat obesity by calculating cost-utility ratios of the treatment modes of dietary counseling, pharmaceutical interventions and bariatric surgery.Generally, the majority of interventions were found to be either cost-saving or very cost-effective in an Israeli setting. Differences in cost-effectiveness...

Smoking is an extremely serious, but reversible, risk factor for many chronic diseases. Multiple effective tobacco control interventions exist. No one single intervention can totally reduce the considerable smoking related burden of disease in terms of treatment costs, morbidity and mortality (around 6,000,000 deaths worldwide in 2010).

Transport programs to encourage walking, paid media advertisements, public relations events with...
