Objectives: Conduct systematic reviews to examine the relationship between timing of introduction or types and amounts of complementary foods and beverages (CFB) and growth, size, and/or body composition outcomes across the lifespan.
Methods: Literature was searched in PubMed, Cochrane, Embase, and/or CINAHL using pre-determined inclusion and exclusion criteria. The systematic review consisted of the following steps: data extraction, risk of bias assessment, qualitative synthesis, conclusion statement development and grading based on strength.
Results: Eighty-one articles examined timing of CFB introduction and 49 examined types/amounts of meat, cereal, fats/fatty acids, sugar-sweetened beverages (SSB), juice and other CFB, and specific dietary patterns. Moderate evidence suggests that introduction of CFB between ages 4-5mo compared to 6mo is not associated with growth, size, and body composition among generally healthy, full-term infants. Limited evidence suggests introduction of CFB before age 4mo may be associated with higher odds of overweight/obesity. Insufficient evidence exists regarding introduction at age 7mo or older and growth, size, or body composition. Moderate evidence suggests that meat or CFB with different fats/fatty acids do not favorably or unfavorably influence growth, size, and/or body composition. However, there is insufficient evidence to determine a relationship between intake of meat or CFB with different fats/fatty acids and overweight or obesity. Limited evidence is available to draw conclusions about the relationship between cereal, SSBs, and juice relative to outcomes. Insufficient evidence is available to draw conclusions about the relationship between other CFB and dietary patterns relative to outcomes.
Conclusions: Additional research, including RCTs, is needed to address gaps and limitations in the evidence on complementary feeding and growth, size, and/or body composition, such as research examining a wider range of specific types of CFB, and that accounts for potential confounders (e.g., milk-feeding, baseline growth status) and reverse causality (e.g., rationale for timing, type, and/or amounts of CFB).
