title: [Birth weight of children born without congenital defects. I. Birthweight percentiles by gestational age].
abstract: We studied the birthweight by gestational age and sex from a population of 14,097 liveborns without congenital defects who were monitored by the Spanish Collaborative Study of Congenital Malformations (ECEMC). We have calculated the curves of percentiles for gestational age in males and females. As our sample size is very large, and it includes births from almost the whole country, we think these curves are enoughly representative of the Spanish population, fitter than the Denver's (1) which are widely utilized. On the other hand, we stress our attention in making curves of birthweight for malformed and not malformed babies separately.
