Abstrakt:	In birth certificate data for Massachusetts resident births from 1978 to 1982, 12-27% of births purportedly under 31 weeks of gestation were probably misclassified, i.e. had birthweight greater than or equal to 2500 g. Correcting for maldistribution of births removed 34% and 23%, respectively, of black and white births with reported gestational ages less than 36 weeks but with implausible weights. Percentages of unknown and incomplete reports of last menstrual period were also significantly higher for blacks. After adjustment, preterm black infants weighed less than whites at each gestational age. The proportion of infants less than 2500 g born at term (greater than or equal to 37 weeks gestation) was higher (although not significantly) among blacks. These findings are consistent with hypotheses that low socioeconomic status negatively affects the rate of intrauterine growth. [ABSTRACT FROM AUTHOR]
