| Popis: | In bariatric surgery, ideal body weight (IBW) is used to calculate excess body weight (EBW) and percent excess weight lost (%EWL). Bariatric literature typically uses the midpoint of the medium frame from older Metropolitan Life Insurance (MetLife) tables to estimate IBW. This is neither universal nor always clinically accurate.The objective of this study was to determine the accuracy of standard IBW formulas compared to MetLife data.Weight loss data from 200 bariatric surgical patients between 2009 and 2011 was used to assess the accuracy of IBW formulas. IBWs assigned from the midpoint of the medium frame and reassigned using different gender targets were compared to standard formulas and a new formula to assess the accuracy of all formulas to both targets.Using standard MetLife data, the mean IBW was 136 lb, the mean EBW was 153.6 lb, and the mean %EWL was 43.8 %. Using the new target baseline, the mean IBW was 137.1 lb, the mean EBW was 152.6 lb, and the mean %EWL was 44 %. Deitel and Greenstein's formula was accurate to 0.3 % of EBW using the standard method, while our new formula was accurate to 0.03 % of EBW.Deitel and Greenstein's formula is most accurate using standard target IBW. The most accurate is our formula using the new MetLife target IBW. |
