Impacto do estado nutricional materno sobre o peso ao nascer de prematuros

Abstract

Introduction: An aggravating factor of prematurity is its influence on birth weight. The present study aimed to evaluate the impact of maternal nutritional status on preterm birth weight. Methods: Cross-sectional study conducted in a maternity hospital located in Maceió-AL, with 381 dyads (puerperal and newborn) in the premature postpartum. Maternal nutritional status was assessed by body mass index (BMI) and gestational weight gain, and birth weight according to INTERGROWTH-21st. Associations were performed by Poisson regression, expressed as prevalence ratio (PR) and respective 95% confidence intervals (95% CI), considering significant p <0.05. Results: Most pregnant women had inadequate gestational weight gain and BMI, where those with excess weight (PR = 2.13; 95% CI = 1.02-1.67 and p = 0.03) and excessive weight gain (PR = 2.82; 95% CI = 1.18-2.51 and p = 0.00) had a higher risk of having premature large for gestational age (LGA) children. Conclusion: Overweight and maternal gestational weight gain influenced the birth of LGA preterm infants.
