Antenatal screening and risk factors for intrauterine growth retardation

Area of Science:

• Obstetrics and Gynecology
• Perinatal Medicine
• Maternal-Fetal Medicine

Background:

• Identifying fetuses that are small for gestational age (SGA) is critical for optimizing perinatal outcomes.
• Small infants can be categorized into genetically small, malformed, or malnourished groups, each with distinct implications.
• Fetal surveillance is primarily beneficial for malnourished SGA infants.

Purpose of the Study:

• To evaluate the combined utility of antenatal risk factors and symphysis-fundus distance in identifying pregnancies with small infants.
• To differentiate between categories of small infants (genetically small, malformed, malnourished) based on antenatal assessment.
• To determine which category of small infants benefits from targeted fetal surveillance.

Main Methods:

• Utilized antenatal risk factors and symphysis-fundus distance measurements in a cohort of pregnancies.
• Analyzed data to identify pregnancies with infants classified as small for gestational age.
• Correlated maternal conditions, pregnancy complications, and environmental factors with infant outcomes.

Main Results:

• Antenatal risk factors and symphysis-fundus distance effectively identify pregnancies with small infants.
• Maternal diseases, pregnancy complications (e.g., hypertension), and environmental factors (e.g., smoking) are associated with malnourished small infants.
• Only the malnourished category of small infants demonstrated a benefit from fetal surveillance.

Conclusions:

• The combination of antenatal risk factors and symphysis-fundus distance aids in identifying small for gestational age infants.
• Maternal health status and environmental exposures are key contributors to fetal malnutrition.
• Targeted fetal surveillance should be focused on malnourished small infants to improve outcomes.
