Summary
Infant formula feeding significantly increases the risk of acute gastrointestinal illness compared to breast milk or cow milk. This heightened risk, particularly for non-viral/bacterial cases, suggests formula properties may play a role.
Area of Science:
- Pediatrics
- Infant Nutrition
- Gastroenterology
Background:
- Acute gastrointestinal illness is a common concern in infants.
- Understanding risk factors is crucial for infant health management.
Purpose of the Study:
- To evaluate the determinants of acute gastrointestinal illness in infants.
- To compare the risk of illness associated with different infant feeding methods.
Main Methods:
- Prospective follow-up of infants under one year.
- Case-control study design, matched by birth month.
- Analysis of gastrointestinal illness episodes based on feeding type (formula, breast milk, cow milk).
Main Results:
- Infants fed formula had a 6x greater risk than breast milk-fed infants and 2.5x greater risk than cow milk-fed infants.
- Formula-fed infants experienced 0.38 more gastrointestinal illness episodes per child in the second six months of life.
- Increased risk was primarily associated with illnesses lacking rotavirus or bacterial agents.
Conclusions:
- Infant formula feeding is associated with a significantly higher risk of acute gastrointestinal illness.
- The increased risk is not explained by factors like iron fortification or formula type for high-risk infants.
- Non-antibody anti-infection properties in cow milk may offer protective benefits, warranting further investigation.
