Complementary feeding and developmental milestones: a systematic review.

Area of Science:

• Pediatric Nutrition
• Developmental Pediatrics
• Evidence Synthesis

Background:

• Systematic reviews were part of a large project examining complementary feeding and child development.
• Previous research explored the connection between infant nutrition and developmental milestones.

Purpose of the Study:

• To describe systematic reviews on complementary food and beverage (CFB) introduction timing, types, and amounts.
• To assess the relationship between CFB consumption and developmental milestones in children up to 24 months.

Main Methods:

• Searched four databases (PubMed, Cochrane, Embase, CINAHL) for relevant studies.
• Conducted data extraction and risk of bias assessment for included systematic reviews.
• Qualitatively synthesized evidence and graded the strength of evidence.

Main Results:

• Three studies examined CFB introduction timing; eight examined CFB types and amounts.
• Insufficient evidence was found to conclude on the relationship between CFB timing or type/amount and developmental milestones.

Conclusions:

• Limited evidence and methodological issues (e.g., reverse causality, study design variation) restrict conclusions.
• Further research is recommended to address evidence gaps in complementary feeding and child development.
