A systematic review and meta-analysis of the association of dietary diversity with undernutrition in school-aged children.

According to the conclusions of this meta-analysis of cross-sectional studies, inadequate dietary diversity increases the risk of undernutrition in growth linear but not in thinness in school-aged children. The findings of this analysis suggest that initiatives that support improvements to the diversity of children's diets to reduce the risk of undernutrition may be warranted in LMICs.
