The effects of infant feeding on rotavirus-induced gastroenteritis: a prospective study
Insights
Breast-feeding does not affect rotavirus infection risk but may lessen illness severity. This study found milder, shorter rotavirus gastroenteritis in breast-fed infants compared to bottle-fed infants.
Area of Science:
- Pediatrics
- Infectious Diseases
- Public Health
Background:
- Rotavirus is a leading cause of severe gastroenteritis in infants worldwide.
- Feeding practices are hypothesized to influence infant susceptibility and disease outcomes.
- Understanding these factors is crucial for developing effective prevention strategies.
Purpose of the Study:
- To investigate the association between infant feeding methods and rotavirus infection.
- To compare the clinical severity of rotavirus gastroenteritis in breast-fed versus bottle-fed infants.
Main Methods:
- A cohort of 197 infants from low-income households was followed during the 1983-84 winter diarrhea season.
- Fecal samples were collected and tested for rotavirus using electron microscopy and ELISA.
- Illness severity was classified as mild or otherwise.
Main Results:
- Rotavirus gastroenteritis attack rates were similar between breast-fed (20%) and bottle-fed (17%) infants.
- Breast-fed infants experienced significantly milder and shorter illnesses (90% mild vs. 36% mild).
Conclusions:
- Breast-feeding appears to moderate the clinical course of rotavirus gastroenteritis, reducing severity without impacting infection rates.
- Findings suggest protective factors associated with breast-feeding warrant further investigation for public health interventions.
Abstract:
The relationship between feeding method and risk of rotavirus infection was studied by following a cohort of 197 infants from low income households through the winter diarrhea season of 1983-84. Fecal specimens were systematically collected and tested for the presence of rotavirus particles by electron microscopy, confirmed by ELISA. The attack rates of rotavirus gastroenteritis were similar for breast-fed and bottle-fed infants (20 per cent, 17 per cent, respectively); however, the clinical course of rotavirus gastroenteritis was quite different. Infants who were breast-fed had illnesses which were characterized by milder symptoms of shorter duration. Of the 10 breast-fed infants who acquired rotavirus gastroenteritis, nine (90 per cent) were classified as mild illnesses while of the 25 bottle-fed infants who acquired rotavirus gastroenteritis, only nine (36 per cent) were classified as having mild illnesses. These data suggest that factors associated with breast-feeding, although not affecting rotavirus infection rates, may moderate the clinical course of rotavirus gastroenteritis.
