Breast-feeding and diarrheal morbidity.

Area of Science:

• Pediatrics
• Public Health
• Nutrition

Background:

• Diarrheal diseases remain a significant cause of infant morbidity and mortality globally.
• Breastfeeding is recognized as a crucial protective factor against infant infections.
• Understanding the specific impact of different feeding patterns on diarrhea risk is essential for public health interventions.

Purpose of the Study:

• To examine the age-specific effects of various breastfeeding patterns on diarrheal morbidity.
• To quantify the risk associated with supplementing breast milk with other liquids or foods.
• To assess the generalizability of findings on infant feeding and diarrhea.

Main Methods:

• Longitudinal survey of over 3000 mother-infant pairs in the Cebu region, Philippines.
• Detailed examination of the sequence of breastfeeding and diarrheal morbidity events.
• Statistical analysis controlling for a wide range of environmental factors contributing to diarrhea.

Main Results:

• Introducing non-nutritive liquids (water, teas) alongside breast milk doubled or tripled diarrhea likelihood.
• Supplementation with nutritive foods or liquids significantly increased diarrhea risk.
• The protective benefits of breastfeeding diminished substantially in the second half of infancy, regardless of supplementation.
• Breastfeeding benefits were marginally greater in urban settings.

Conclusions:

• Exclusive breastfeeding is critical for reducing infant diarrhea, especially in the first year of life.
• Supplementation with any additional liquids or foods increases diarrhea risk and negates breastfeeding benefits.
• Findings underscore the importance of promoting exclusive breastfeeding for infant health in diverse populations.
