[The study of Apgar score and infant birth weight in the central Taiwan]

The objective of this study was to assess the relationship between birth weight and the Apgar Score. We collected data on the birth weights and the 1 min and 5 min Apgar Score of new born infants between 1982 and 1987 at a teaching hospital in Central Taiwan. Compared to babies with normal Apgar Score, infants with low Apgar Scores were found to born with low and very low birth weights. In the 1 min of life test, the relative risks of low birth weights among infants with Apgar Scores of 0 to 3 and 4 to 6 were 115.0 and 5.9 times higher than those of normal infants, respectively. In the very low birth weight category, the relative risks of the above score were 252.5 and 51.1, in this order. In the 5 min of life test, the relative risks of the above scores were 16.2 and 12.1 in the low birth weight category, respectively. However, among babies of very low birth weight, the relative risks of the same scores were 121.2 and 84.9, in this order. In conclusion, the 5 min Apgar Score might be a useful prognostic index for the relationship between health and birth weight of new born infants.
