Abstract

Objective: To evaluate maternal conditions related to low birth weight and neonatal complications. Methods: Cross-sectional cohort stratifying newborns weighing less than and greater than or equal to 2,500g. Results: Associated maternal and fetal factors include: smoking (11.30% vs 6.8% p=0.018), high-risk prenatal care (38.08% vs 20.72% p=0.00), previous premature birth (9.34% vs 5.48% p=0.023), hypertensive disease during pregnancy (31.7% vs 13.16% p=0.00), previous hypertension (12.29% vs 4.93% p=0.00) and urinary tract infection (32.68% vs 24.23% p=0.005), neonatal ICU admission (63.39% vs 6.03% p=0.00) and need for mechanical ventilation (51.60% vs 7.46% p=0.00). Conclusions: Smoking, high-risk prenatal care, previous premature birth and previous pathologies were associated with low birth weight, while this condition increased the chance of adverse fetal outcomes.
