Infantile colic and type of milk feeding

Area of Science:

• Pediatrics
• Infant Nutrition
• Gastroenterology

Background:

• Infant colic is a common condition affecting healthy newborns.
• The etiology of colic remains largely unknown, with various factors implicated.
• Dietary factors, including milk protein hypersensitivity, are often suspected causes of colic.

Purpose of the Study:

• To investigate the prevalence of colic in relation to different milk feeding types.
• To assess the association between intestinal damage markers and colic.
• To evaluate adverse reactions to cow's milk in colicky infants.

Main Methods:

• Parental questionnaires were used to determine colic prevalence in 964 infants (2-52 weeks).
• Fecal alpha 1-antitrypsin and hemoglobin concentrations were measured in a subset of infants (206 and 200, respectively) to assess intestinal damage.
• Adverse reactions to cow's milk introduction were monitored in previously colicky infants.

Main Results:

• Colic prevalence was similar across human milk (20%), formula (19%), and mixed feeding (21%).
• No increased likelihood of intestinal damage (fecal alpha 1-antitrypsin or hemoglobin) was found in infants with colic.
• Adverse reactions to introducing cow's milk were infrequent in infants with prior colic.

Conclusions:

• The study suggests that dietary protein hypersensitivity is unlikely to be the primary cause of colic in most healthy young infants.
• Feeding type does not appear to significantly influence colic prevalence.
• Further research may be needed to explore other potential etiologies of infant colic.
