Introduction and objectives: The determination for risk factors have proved to be useful in perinatal interventions. To identify factors influencing risk of intrauterin growth retardation (IUGR: birth weight <10 percentile) and prematurity (P: gestacional age < 37 weeks) in the districts of La Costa and Gral. Lavalle, Buenos Aires, Argentina and to determine the effects of maternal factors on fetal growth. Population and study design. Retrospective study. A total of 1002 mothers and newborns were evaluated. Material y Méthods: They were included in the Perinatal informatic System from 01-01-96 to 30-04-97 with complete data of the variable (more than 90%). We selected 14 factors: age, marital status, education, parity, interpregnancy interval, height, weight at first and last control, gestational age at first control, gestational weight gain, body mass index, gravidic pathologic, smoking and number of prenatal controls. Neonatal anthropometry included weight, height, body mass index and head circumference. An ANOVA and Mantel-Haenszel stratified by age analysis were carried out. Results: Maternal anthropometry influenced risk to IUGR and pregnancy weight for P. Pathology during pregnancy and smoking influenced both adverse results: FGR and P. There were statistically significant differences in growth between newborns from exposed and non-exposed mothers. Neonatal body mass index was less affected. This study emphasizes in the recollection of some data that may be helpful in the planification of strategies for the reduction of two pathologies that influence perinatal morbimortality
