A prospective study was conducted in the North Arcot District, Tamil N
adu State, India, to determine the correlates of intrauterine growth r
ate (IUGR), which was assessed using Yerushalmy's classification based
on birth weight and gestational age. Using a log-linear model, we stu
died 4220 single live births with complete information on IUGR and obs
tetric, paternal, maternal, and familial factors. Parental body weight
s, consanguinity, and area of residence were identified as important p
redictors of IUGR.
