Table 4.
Twenty-four hour metabolic rate and physical activity of infants born to normal weight and obese biological mothers
| Parameters for infants | Biological Mothers | |
| Normal weight | Obese | |
| 24-hr EE (kcal/kg body weight)1 | 76.0 ± 5.2 | 74.3 ± 4.3 |
| RMR (kcal/kg body weight)2 | 65.0 ± 5.0 | 64.9 ± 3.4 |
| SMR (kcal/kg body weight)3 | 63.0 ± 4.3 | 64.6 ± 4.1 |
| 24-hr PA (oscillations/min/kg body weight)4 | 2.9 ± 0.4 | 5.0 ± 2.4 |
| RQ (VCO2/VO2)5 | 0.84 ± 0.03 | 0.89 ± 0.02 |
1 24-hr EE = Twenty four hour energy expenditure expressed per kg body weight
2 RMR = 24-hour resting metabolic rate expressed per kg body weight
3 SMR = 24-hour sleeping metabolic rate expressed per kg body weight
4 PA = physical activity as determined by the amount of oscillations in weight (g) derived from the balance within the EMTAC enclosure. Data includes periods of sleep
5 RQ = Respiratory quotient determined as the rate of carbon dioxide production/oxygen consumption in liters
