Sleep apnoea in babies born after in vitro fertilization

Area of Science:

• Neonatal Health
• Developmental Pediatrics
• Reproductive Medicine

Background:

• The incidence of births resulting from in vitro fertilization (IVF) is rising globally.
• Limited data exists on the respiratory health, specifically apnea risk, of infants conceived via IVF.
• Understanding respiratory patterns in IVF infants is crucial for assessing their developmental trajectory.

Purpose of the Study:

• To investigate and compare the incidence of apnea and periodic breathing in infants conceived via IVF versus naturally conceived infants.
• To evaluate the respiratory maturity of IVF-conceived infants.

Main Methods:

• A polysomnography study was conducted over 8 hours on 50 IVF infants and 50 matched, naturally conceived infants.
• Infants were healthy, matched for gestational age (>38 weeks), birth weight, sex, and age (6-11 weeks post-term).
• Apnea events, including obstructive, central, and periodic breathing, were recorded and analyzed.

Main Results:

• The incidence of obstructive and isolated central apnea was similar between IVF and control groups.
• IVF infants demonstrated a significantly higher frequency of periodic breathing episodes compared to controls (P < 0.01).
• Single IVF infants showed more short central apneas than IVF twins (P < 0.001), a difference not observed in controls.

Conclusions:

• Infants conceived via IVF exhibit a higher prevalence of periodic breathing episodes, indicative of a less mature respiratory pattern.
• These findings suggest potential differences in respiratory development in IVF-conceived infants compared to their naturally conceived counterparts.
• Further research into the long-term respiratory implications for IVF infants is warranted.
