Summary

Small for Gestational Age (SGA) infants born to older mothers or those with less education faced higher risks. SGA also increased neonatal mortality risk, even when accounting for gestational age.

Area of Science:

  • Obstetrics and Gynecology
  • Neonatal Health
  • Public Health Research

Context:

  • Analysis of birth certificate data to identify risk factors for Small for Gestational Age (SGA) infants.
  • Investigating the association between intrauterine growth retardation and neonatal mortality.
  • Study conducted in Santo André, S. Paulo Metropolitan area, Brazil, using data from 2,251 live births between January 1 and June 30, 1992.

Purpose:

  • To analyze birth certificate variables as risk factors for SGA.
  • To determine if intrauterine growth retardation is a risk factor for neonatal mortality.
  • To assess the relationship between SGA, maternal factors, and neonatal outcomes.

Summary:

  • 4.3% of live births were SGA.
  • SGA was significantly more prevalent in preterm and post-term births, and among infants of mothers aged 35+ or with incomplete primary education.

  • SGA infants exhibited a higher risk of neonatal death, independent of gestational age.
  • Impact:

    • Retarded intra-uterine growth is a significant risk factor for preterm births in populations with low low-birthweight rates.
    • Improved gestational age recording on birth certificates could aid in evaluating intrauterine growth retardation.
    • Highlights the need for targeted interventions for SGA prevention and management, especially in vulnerable maternal populations.
