[Associated factors in newborns with intrauterine growth retardation].
OBJECTIVE
To identify the risk factors implicated in the intrauterine growth retardation (IUGR) of neonates born in a social security institution.


METHODS
Case controls design study in 376 neonates: 188 with IUGR (weight < 10 percentile) and 188 without IUGR. When they born, information about 30 variables of risk for IUGR were obtained from mothers. Risk analysis and logistical regression (stepwise) were used.


RESULTS
Odds ratios were significant for 12 of the variables. The model obtains by stepwise regression included: weight gain at pregnancy, prenatal care attendance, toxemia, chocolate ingestion, father's weight, and the environmental house.


CONCLUSIONS
Must of the variables included in the model are related to socioeconomic disadvantages related to the risk of RCIU in the population.
