摘要: Abstract Objective To examine the accuracy and precision of 12 equations or tables for predicting resting metabolic rate (RMR) in obese persons. Design Observational (correlational) study. Setting Obesity Research Center, St Luke's/Roosevelt Hospital, New York, NY. Subjects/samples One hundred twenty-six (73 women, 53 men) healthy, subjects recruited through Center's Weight Control Unit. Measures RMR by indirect calorimetry. height were measured to nearest 0.1 kg 1 cm. Statistical analyses performed Bivariate regression predicted on RMR; paired t tests difference between means RMR. Results Of prediction equations, 6 had intercepts slopes that significantly different from 0 1, respectively. With two exceptions, accounted 56% 63% variance The Robertson Reid (1952) equation Fleisch (1951) best with our sample. Applications/conclusions are recommended clinical use patients. J Am Diet Assoc. 1993; 93: 1031–1036.
