title: Apgar score and infant mortality in Puerto Rico.
abstract: This study has as its objectives: 1) to examine the association between Apgar score and a set of demographic and sociodemographic variables so as to assess its usefulness as an indicator of the physical conditions of the newborn; 2) to determine if Apgar score in Puerto Rico is a good predictor of the newborn probability of surviving during his first year of life. For this purpose the 1990 live births and infant deaths data was utilized. The results indicate a direct relation between Apgar score with mother's schooling, father's occupation, and number of prenatal visits. Apgar score shows, also, an U curve type relationship with birthweight and gestational age, while it was found to be higher in private than in public hospitals. One of the most important findings was the strong association between infant mortality and Apgar score, even when the effect of other important independent variables such as birthweight and gestational age were held constant. These results demonstrate that, in spite of its criticisms Apgar score seems to be an excellent indicator of the newborn conditions at birth and a very good predictor of infant mortality in Puerto Rico.
