Abstract
We evaluated the correlation of the methods for estimating energy requirements using standard body weight (SBW) and basal energy expenditure (BEE) with body weight change in patients with diabetes. One hundred sixty-four patients were included in the analyses. The remainder, after energy intake was subtracted from the energy requirement (as estimated by SBW), was correlated with body weight change from day 2 (r=-0.26). The remainder, after energy intake was subtracted from the energy requirement (as estimated by the BEE prediction equations), was correlated with body weight change from day 2. The correlation coefficients of the prediction equations were -0.48 (Harris-Benedict), -0.42 (Oxford), -0.44 (National Institute of Health and Nutrition), and -0.40 (Kyoto University). The correlation coefficients with body weight change from day 4 were -0.34 (SBW), -0.51 (Harris-Benedict), -0.48 (Oxford), -0.50 (National Institute of Health and Nutrition), and -0.48 (Kyoto University). All P values were <0.001. The BEE prediction equations, including the Kyoto University equation (BEE=10×weight-3×age+750+125 [if male]) were more strongly correlated with body weight change than the equation using standard body weight.
