The emerging predictors of childhood undernutrition include household food insecurity (HFI) and inadequate diet diversity (DD). Geographical, socio-cultural, economic, and demographic factors contribute to HFI. Earlier, HFI was often considered an outcome of hunger and poverty leading to undernutrition. The increasing availability of data related to childhood DD and its direct association with undernutrition indicates that DD could mediate the relationship between HFI and undernutrition. This narrative review examined the association of HFI and/or DD with undernutrition in children younger than 5 years in the Indian subcontinent; and the current programmes and policies. The current evidence showed a possible association between HFI and DD either independently or together with childhood undernutrition. Until now, nutrition-specific interventions to address moderate and severe forms of undernutrition were focused, with a limited attention on nutrition-sensitive approaches to improve HFI and DD. Interventions which improve HFI and DD may be included in the existing programmes and would help address the undernutrition in children younger than 5 years., Competing Interests: No funding was received for the preparation of the present review.

Objective: The present systematic review explored compliance status with school food policies in Europe and the Western Pacific regions, challenges and facilitators of policy compliance, and its impact on children's diets and nutrient intakes., Research Methods: An electronic search for full-text research articles published between January 2009 and July 2023 was conducted in Science Direct and PubMed scientific databases., Results: A total of 659 titles and abstracts were screened, and final data was extracted from 34 included studies. Results showed low compliance with the school food policy in Europe and the Western Pacific regions. The European schools chad better compliance than the Western Pacific, and supportive interventions improved policy adherence. Impact assessment studies reported that the implementation of the school food policy increased fruit and vegetable consumption, thus increasing nutrient intakes (vitamin A, vitamin D, iron, calcium, folate, and dietary fibers). However, its impact on the availability and consumption of foods high in fat, sugar, and salt (HFSS) was less conclusive. The effects of the policy on the school food environment indicated no significant improvement., Conclusion: Results highlighted the need for additional support and surveillance at the school level to ensure adequate policy compliance., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.
