OBJECTIVE To determine the effects of body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) on outcomes after liver resection performed at Veterans Affairs medical centers. DESIGN, SETTING, AND PATIENTS We queried the Veterans Affairs Surgical Quality Improvement Program database for liver resections (2005-2008) and grouped the patients into 5 BMI categories: normal weight (BMI 18.5-24.9), overweight (BMI 25.0-29.9), obese class 1 (BMI 30.0-34.9), obese… CONTINUE READING

Among these groups , higher BMI was associated with increased rates of hypertension ( 52% , 61% , 77% , 77% , and 73% , respectively ; P = .002 ) and diabetes ( 18% , 27% , 36% , 39% , and 45% , respectively ; P = .04 ) and lower incidence of smokers ( 53% , 35% , 30% , 16% , and 9% , respectively ; P < .001 ) .
