Abstract
In view of correlations found between levels of neonatal bilirubin elevations and subnormal developmental quotients on follow-up, and a 10 to 15% occurrence of HBR (bilirubin levels ≥ 12 mg%), a study to datermine factors associated with HBR was undertaken.
During an 18 month pariod randomly selected healthy term infants ware enrolled in the study. A bilirubin determination was done at the time of hospital discharge (60 to 96 hours of age), and both mother's and infant's charts were reviewed for factors such as mother's age and health, parents' race, infant's sex, health status, type and time of feeding, and weight changes between birth and discharge.
Analysis of the data revealed no significant difference in HBR between boys and girls. There was, however, a difference in bilirubin elevations above 8 mg%: boys 56%, girls 41% (p<0.05). 27% of the 51 Oriental patients and 7% of the other 179 infants had HBR (p<0.01). Preliminary data reveals that 4 of 56 bottle-fed versus 11 of 45 breastfed infants had HBR (p<0.05). Groups of infants with differing times of initial feeding and differing birth-discharge weight incremants had no differences in HBR.
