Investigating the Effectiveness of School-based Nutrition Interventions (SBNIs) on Children’s Nutrition Statuses and Healthy Habit Maintenance: A Literature Review
Childhood obesity and diet inadequacies are one of the most serious global health concerns to date, affecting over 340 million children (ages 5-19 years) worldwide. Effective health promotion and preventive measures are needed to address the serious health concerns affecting this population. School-based nutrition interventions (SBNIs) act as a potential avenue to support children's nutrition and life-long healthy habit maintenance by demonstrating nutrition knowledge and techniques to support healthy decision-making. This paper aims to investigate the effectiveness of SBNIs on nutrition and healthy habit maintenance for children between the ages of 5-19 years old. Literature was screened using the PubMed electronic database, yielding a total of 23 peer-reviewed articles to be included in this review. These studies highlighted that SBNIs that utilized multi-component approaches, elicited long-term and continuous implementation efforts, communal engagement, and provided educator support and effective resources indicated the highest amount of positive health outcomes and behaviours in children. Future research is needed to further investigate the long-term implementation of SBNIs, and future policies should work towards adopting similar strategies to help promote healthy livelihoods for all children worldwide.
