Dietary modifications for infantile colic.

Area of Science:

• Pediatrics
• Gastroenterology
• Nutrition

Background:

• Infantile colic, defined as prolonged crying in infants, affects 17-25% of newborns.
• Its exact cause is unknown but likely multifactorial, involving diet, gut flora, and motility.
• The role of dietary modifications in managing infantile colic remains controversial.

Purpose of the Study:

• To evaluate the effectiveness of dietary modifications in reducing colic symptoms in infants under four months old.
• To synthesize evidence from randomized controlled trials (RCTs) on dietary interventions for infantile colic.

Main Methods:

• Searched multiple databases (CENTRAL, MEDLINE, Embase) and trial registers for relevant RCTs and quasi-RCTs.
• Included studies involving infants younger than four months with colic, comparing dietary changes against other interventions or placebo.
• Primary outcome was crying duration; secondary outcomes included response to intervention and parental quality of life.

Main Results:

• Fifteen RCTs with 1121 infants were included, all small and at high risk of bias.
• Evidence quality was assessed as very low; benefits of hydrolysed formulas were inconsistent.
• Some interventions like low-allergen maternal diet and certain formulas showed potential but with limited, low-quality evidence.

Conclusions:

• Current evidence on dietary modifications for infantile colic is sparse, of very low quality, and at high risk of bias.
• Due to study limitations and insufficient data, no specific dietary intervention can be recommended.
• Further high-quality research with robust methodology and clinically significant outcomes is necessary.
