Abstract

Abstract : Background . Malnourished infants are small for age and weight. Objectives . Determine profiles in 24-hour energy metabolism in recovering malnourished infants and compare to similarly aged healthy controls. Methods . 10 malnourished infants (58.1 ± 5.9 cm, 7.7 ± 5.6 months) were healthy prior to spending 22 hours in the Enhanced Metabolic Testing Activity Chamber for measurement of EE (kcal/min), sleeping metabolic rate (SMR; kcal/min), respiratory quotient (RQ;VCO 2 /VO 2 ), and physical activity (PA; oscillations in wt/min/kg body weight). Metabolic data were extrapolated to 24 hours (kcal/kg/d). Energy intake (kcal/kg/d) and the proportions (%) of carbohydrate, protein, and fat were calculated. Anthropometrics for malnourished infants were obtained. Statistical differences (P < .05 ) between groups were determined (SPSS, version 13). Results . In comparison to controls, malnourished infants were lighter (4.1 ± 1.2 versus7.3 ± 0.8 kg;P < .05 ), had less body fat % (10.3 ± 7.6 versus25.7 ± 2.5 ), and lower BMI (12.0 ± 1.7 versus15.5 ± 1.5 ;P < .05 ). In contrast, they had greater energy intake (142.7 ± 14.6 versus85.1 ± 25.8 ;P < .05 ) with a greater percentage of carbohydrates (55.1 ± 3.9 versus47.2 ± 5.2 ;P < .05 ). However, malnourished infants had greater 24-hour EE (101.3 ± 20.1 versus78.6 ± 8.4 ;P < .05 ), SMR (92.6 ± 17.1 versus65.0 ± 3.9 ;P < .05 ), and RQ (1.00 ± 0.13 versus0.86 ± 0.08 ;P < .05 ) along with a lower amount of PA (2.3 ± 0.94 versus4.0 ± 1.5 ;P < .05 ). Conclusions . Malnourished infants require more energy, possibly for growth.
