Abstract:
Anthropometry, basal metabolic rate (BMR), and resting energy expenditure (RMR) measured by indirect calorimetry and total daily energy expenditure (TDEE) by the minute-by-minute heart rate (HR) method have been studied in 52 school-aged girls 6-16 years and 46 nonpregnant, nonlactating women 19-43 years of age. BMR, RMR, and TDEE increased with age in children, reaching approximate adult values by 15 years. TDEE averaged 9.29 ± 2.32 MJ/d in women 19-43 years. The ratio RMR/BMR averaged 1.27 ± 0.29 across all age groups. TDEE/BMR varied from 1.41 ± 0.28 to 1.62 ± 0.37 in the girls and averaged 1.78 ± 0.43 in adults. Application of empirical equations to estimates of BMR showed that those of Schofield gave values of +3.1% (P = 0.03) and of Henry and Rees -3.8% (P = 0.052) of measured BMR (Schofield [1985] Hum Nutr Clin Nutr 39C [Suppl 1]:5-41; Henry and Rees [1991] Eur J Clin Nutr 45:177-185). The pattern of daily energy expenditure is highly variable across age groups during the awake portion of the day (0700-2000 hours). In the averaged data of women at home, there is a gradual increase in the morning, a decline at noon, followed by some increase in the early afternoon and decline in late afternoon and early evening. © 1996 Wiley-Liss, Inc.
