This meta-analysis evaluates the impact of egg supplementation on growth in children aged 6 months to 18 years. The study systematically searched PubMed and Healthline for interventional trials and included seven studies with 3,575 participants. The results showed that children in the egg supplementation groups had significantly greater increases in height (0.47 cm, p < 0.01) and weight (0.07 kg, p = 0.03) compared to those in the control groups. Subgroup analyses indicated that these benefits were more pronounced in children under 2 years old. The study concludes that eggs are an affordable and nutritious option for improving growth in children, but more studies with longer interventions are needed. The findings suggest that early intervention with egg supplementation could be particularly beneficial for young children in low- and middle-income countries.This meta-analysis evaluates the impact of egg supplementation on growth in children aged 6 months to 18 years.
