Effect of thermal environment and caloric intake on head growth of low birthweight infants during late neonatal period.
In order to assess the effects of ambient thermal conditions on postnatal head growth in low birth weight infants, 42 asymtomatic neonates were reared under 4 combinations of caloric intake and thermal environment after the first week of life. Exposure to a subthermoneutral temperature (abdominal skin temperature of 35 degrees C), together with a relatively low caloric intake (120 cal/kg per day), was associated with significant retardation of head growth over a 2-week study period.
