Body Composition and Basal Metabolic Rate in Women with Type 2 Diabetes Mellitus

Abstract

Objective. The aim of this study was to determine which of the seven selected equations used to predict basal metabolic rate most accurately estimated the measured basal metabolic rate. Methods. Twenty-eight adult women with type 2 diabetes mellitus participated in this cross-sectional study. Anthropometric and biochemical variables were measured as well as body composition (by absorptiometry dual X-ray emission) and basal metabolic rate (by indirect calorimetry); basal metabolic rate was also estimated by prediction equations. Results. There was a significant difference between the measured and the estimated basal metabolic rate determined by the FAO/WHO/UNU (P value < 0.021) and Huang et al. (P value ≤ 0.005) equations. Conclusion. The calculations using Owen et al's. equation were the closest to the measured basal metabolic rate.

Energy Expenditure in People with Diabetes Mellitus: A Review

“…The Huang and Martin equations presented comparable coefficients of determination ( r 2 = 0.75 and 0.79, respectively) and had better results as compared with the Harris–Benedict equation (30, 80). Besides, de Figueiredo Ferreira et al (83) showed an overestimation of BEE (MD = 115 kcal/day) in women with DM with this equation. The Ikeda and Martin equations presented a lower RMSE (103 and 136 kcal/day, respectively) than the other general equations (140–209 kcal/day) (79, 80).…”

“…The Ikeda and Martin equations presented a lower RMSE (103 and 136 kcal/day, respectively) than the other general equations (140–209 kcal/day) (79, 80). Finally, the Gougeon equation, taking into account the glycemic status, presented no significant difference with IC [MD = 7.4 kcal/day ( p  = 0.845) and bias = −0.5 and 1.6%] (29, 83). …”

“…Finally, Miyake et al (81) and de Figueiredo Ferreira et al (82) observed no significant difference with IC (MD 2  = −19 to 42.3 kcal/day). With the Mifflin–St Jeor equation, studies in patients with DM show an under/overestimation of BEE by −126 to 160 kcal/day (80, 81, 83), or no significant difference (29, 78). The Ganpule equation presented no difference with the reference measure (bias 3  = 4.5%) (79) or underestimated BEE by −110 kcal/day (81).…”

Basal metabolic rate in Brazilian patients with type 2 diabetes: comparison between measured and estimated values

“…Predictive equations for estimating BMR were selected by searching previous publications on this subject (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21). To be included, the equations had to have been developed for adults, men, and women, and based on body weight, height, age, sex, and/or fat mass (FM).…”

“…In patients with type 2 diabetes data on BMR prediction equations have been previously described (13,14,(16)(17)(18)(19)(20)(21)(22), however, in Brazilian diabetic patients it was scarcely investigated (19). Indeed, one study that included only Brazilian obese women with type 2 diabetes, the equation of Mifflin-St. Jeor underestimated BMR in -2.6% and the FAO/WHO/UNO equation overestimated BMR in 10.6% as compared with IC (19). Two other studies proposed formulas for predicting BMR in diabetic patients, irrespective of sex (20,21).…”
