School-based health and nutrition interventions addressing double burden of malnutrition and educational outcomes of adolescents in low- and middle-income countries: A systematic review.

School system is a promising platform for addressing all forms of malnutrition in adolescents. However, little is known about the impact of integrated school health and nutrition programmes on adolescent nutrition and educational outcomes in low- and middle-income countries (LMICs). This systematic review sought to characterize school-based health and nutrition interventions among adolescents in LMICs and analyze their effects on nutritional status and educational outcomes.
