Resting metabolic rate and body composition in stunted and nonstunted children. 1996

The resting metabolic rate (RMR) and body composition of 34 stunted children (height-for-age < or = 1.5 SD) aged 7-8 y were compared with that of two groups of nonstunted control subjects (height-for-age > or = -1.0 SD) matched for either age and sex or height and sex. No significant group differences were found in percentage lean body mass (LBM). The RMR of the stunted children (4702 +/- 570 kJ/d) was significantly lower than that of both the age-matched (5802 +/- 616 kJ/d) and height-matched (5269 +/- 663 kJ/d) groups (ANOVA, P < 0.001). However, in a multiple-regression model including sex and LBM, the RMRs of the stunted and age-matched groups were not significantly different, suggesting that the stunted children's smaller LBM accounted for their lower RMR. This suggests that the composition and metabolic activity of the LBM is unaffected by stunting. The younger, height-matched control subjects had significantly higher RMRs than the stunted children after adjustment for LBM (P < 0.001). This may have been due to age-related changes in the composition of LBM.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D012044	Regression Analysis	Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.

D001481	Basal Metabolism	Metabolism (e.g., heat production) of an organism in an inactive, awake, fasting state. It may be determined directly by means of a calorimeter or indirectly by calculating the end products of oxidation within the organism or from the amount of oxygen utilized.
