The objective of this study was to investigate the determinants of LBW. Cross-sectional study of descriptive population-based involved 384 mothers attended in a public hospital. Forms with closed questions were used on the socioeconomic, demographic condition of pregnancy and nutritional standard features, and anthropometric measurements of prenatal card. The results showed an incidence of LBW infants 6.5%, not registering this association influence of socioeconomic variables (p> 0.05). In relation to maternal characteristics, the number of consultations in prenatal care, the previous history of abortion and the type of delivery showed a statistically significant relationship in determining the BPN (p <0.05). Among LBW infants 7.3% were children of adolescents (p> 0.05), and zero the occurrence of this event in mothers with older age (≥ 35 years). Analysis of these results shows a low occurrence of LBW in the universe studied, however it reinforces the need to implement a program of assistance and guidance to more efficient prenatal care for pregnant women teens.
