Insights

Identifying combined maternal, neonatal, and social risks is key for preterm infant development. High social or neonatal risks, but not maternal risks alone, were linked to poorer outcomes at 3 months.

Area of Science:

  • Developmental Pediatrics
  • Neonatal Research
  • Public Health

Background:

  • Preterm infants are at elevated risk for developmental impairments.
  • Maternal pregnancy complications, neonatal morbidity, and social adversity can cumulatively worsen these risks.
  • Understanding the interplay of these factors is crucial for early intervention.

Purpose of the Study:

  • To identify clusters of maternal, neonatal, and social risk factors in preterm infant-mother dyads.
  • To investigate the association between these risk clusters and infant cognitive/motor outcomes.
  • To inform targeted follow-up strategies for vulnerable preterm infants.

Main Methods:

  • Two-step cluster analysis of data from 222 mother-preterm infant dyads.
  • Risk factors included maternal, neonatal, and social variables.
  • Mixed-effects linear regression models assessed outcomes at 3 and 12 months corrected age.

Main Results:

  • Four distinct risk profiles were identified, ranging from low risk to high risk in specific domains.
  • Infants in high social risk and high neonatal risk profiles showed significantly lower 3-month motor scores compared to the low-risk group.
  • No significant difference in outcomes was found for the high maternal risk profile alone.

Conclusions:

  • An intersectional approach is essential for understanding developmental vulnerability in preterm infants.
  • Simultaneous assessment of maternal, neonatal, and social risks aids in early identification.
  • Person-centered risk profiles highlight the need for individualized, multidisciplinary follow-up care.
