摘要
Heart rates of 46 breast-fed and formula-fed infants were monitored continuously for approximately 18 h at 1 or 4 months of age. Heart rate differed significantly by age (1 month > 4 months; p < 0.001) and feeding mode (breast-fed < formula-fed; p < 0.001). Approximately 58% of the variability in heart rate could be attributed to feeding mode, sex, and age. Heart rate was correlated significantly with energy intake (r = 0.60; p < 0.001), but not sleeping metabolic rate or total daily energy expenditure. Energy intake accounted for none of the variability in heart rate beyond that explained by feeding mode, sex, and age.
