Birth weight of infants with spina bifida cystica

Area of Science:

• Perinatology
• Developmental Pediatrics
• Public Health

Background:

• Neural tube defects (NTDs) are congenital abnormalities affecting the brain and spine.
• Spina bifida cystica is a common and severe form of NTD.
• Birth weight is a critical indicator of infant health and developmental outcomes.

Purpose of the Study:

• To investigate the association between spina bifida cystica and birth weight.
• To determine if infants with spina bifida cystica are lighter at birth compared to controls.
• To explore potential factors contributing to birth weight differences.

Main Methods:

• Comparative analysis of birth weights between singleton infants with spina bifida cystica and a control group without NTDs.
• Statistical evaluation of mean birth weight differences, considering sex.
• Assessment of infant size relative to gestational age.

Main Results:

• Infants with spina bifida cystica (n=189) had statistically significantly lower mean birth weights than controls (n=3816).
• Birth weight deficits were observed in both male (0.20 kg less) and female (0.24 kg less) infants with spina bifida.
• The reduced birth weight was primarily attributed to infants being small for their gestational age, not parity or social class.

Conclusions:

• Spina bifida cystica is associated with a significant reduction in birth weight.
• Infants with spina bifida are often born light for gestational age, indicating potential intrauterine growth restriction.
• These findings highlight the impact of NTDs on fetal growth and development.
