Correlation of Weight, BMI, and Prevalence of Pressure Ulcers First Author: Catherine VanGilder Authors: Catherine VanGilder, BS, MT, CCRA, Stephanie Meyer, Gail Lanigan, RN, and Gordon MacFarlane, PhD The 2006 International Pressure Ulcer PrevalenceTM Survey included BMI data for 64,372 of the 92,192 adults surveyed. The BMI data showed 5.5% of all patients considered underweight (BMI<18.5), 31.3% normal (BMI 18.5-24.9), 27.7% overweight (BMI = 25-29.9), 25.7% obese (BMI = 30-39.9), 9.8% morbidly obese (BMI = 40 +), with 2.8% having BMI's > 50. Overall prevalence was greatest in the underweight (25.3%), decreased with normal (16.6%), overweight (12.2%), and obese (10.5%), and increased at BMI>50 (12.3%). Facility acquired prevalence followed the same trends. Mean weights per BMI class were 104 lbs, 139 lbs, 171 lbs, 203 lbs, 245 lbs, and 311 lbs respectively. Weight groups were divided at 50 pound intervals. The mean BMI per weight class indicated those under 100 lbs as underweight, under 150 lbs as normal, under 200 lbs as overweight and above 200 lbs as obese. Prevalence was 25.0%, 16.9%, 12.8%, 10.3%, 10.5%, 12.0%, 15.1%, 13.8%, 17.5%, and 19.2% respectively. 35.5% of the patient population is considered obese by BMI, however, only 7.5% of the population is over 250 lbs., and 24.3% is over 200 lbs. Prevalence is highest in the underweight population, then again rises after 300 pounds. |
