We recently examined the association of body mass index (and other anthropometric measures) with survival in 1472 patients with peripheral vascular disease. Underweight patients had very high mortalities. Surprisingly patients that were obese and overweight had improved survival compared to normal weight patients. The findings potentially implicate poor nutrition and inactivity as modifiable risk factors in these patients. These findings have been published in the peer-reviewed journal Artherosclerosis (Atherosclerosis 2013; 229:549-55).
