Insights

Small for gestational age (SGA) infants incur higher healthcare costs than appropriate for gestational age (AGA) infants. This independent factor increases maternal and infant hospital expenses through the first year of life.

Area of Science:

  • Neonatal care
  • Perinatal health economics
  • Public health

Background:

  • Small for gestational age (SGA) infants face increased risks for preterm birth complications and adverse perinatal outcomes.
  • These outcomes are partly attributed to premature birth associated with SGA status.
  • Evaluating the economic impact of SGA is crucial for understanding healthcare resource allocation.

Purpose of the Study:

  • To assess the healthcare costs associated with small for gestational age (SGA) infants compared to appropriate for gestational age (AGA) infants in France.
  • To differentiate the cost contributions of prematurity versus fetal growth restriction in SGA infants.
  • To analyze costs from pregnancy through the infant's first year of life.

Main Methods:

  • A cross-sectional, population-based study utilizing French national hospital discharge data (2011).
  • SGA infants defined as birth weight below the 10th percentile; AGA infants between the 25th and 75th percentile.
  • Hospital costs calculated from the hospital perspective for mothers and infants using Diagnostic Related Groups and national cost data.

Main Results:

  • In 2011, 10.9% of births were SGA (84,688 infants).
  • SGA infants incurred an average of €2,783 higher costs than AGA infants, adjusted for gestational age.
  • Maternal and infant hospital costs for SGA accounted for 23% of total delivery costs, driven by higher complication rates, readmissions, and longer hospital stays.

Conclusions:

  • Small for gestational age (SGA) is an independent factor contributing to increased 1-year hospital costs for both mothers and infants.
  • Targeted interventions for SGA infants may reduce long-term healthcare expenditures.
  • Understanding the economic burden of SGA is essential for healthcare policy and planning.
