Compared with patients with a BMI of 26.3 to 29.6, those with a value below 23.1 had a significantly higher risk of death (adjusted OR 1.40, 95% CI 1.25 to 1.58), according to an analysis of 189,533 surgeries performed in 2005 and 2006 and recorded in the National Surgical Quality Improvement Program (NSQIP) database.
Patients with higher BMI values above 23.1 -- including the morbidly obese -- had about the same risk of 30-day mortality as the moderately overweight, George J. Stukenborg, PhD, of the University of Virginia in Charlottesville, and colleagues, reported online in Archives of Surgery. MedPage Today
