Association of food insecurity with anemia in children and adolescents: a systematic review and meta-analysis of observational studies.
Background: Food insecurity, characterized by limited access to adequate and safe foods, is a prevalent global issue affecting millions. Anemia, often stemming from insufficient iron intake, is a common health concern, especially in children. Although the association between household food insecurity and anemia risk has been studied, findings remain inconclusive. This systematic review and meta-analysis of observational studies aim to provide a clearer understanding of this relationship.
Methods: A comprehensive search of PubMed, Web of Science, Scopus, and Google Scholar was conducted up to January 2024. Studies that reported odds ratios (ORs) with 95% confidence intervals (CIs) on the association between food insecurity and anemia risk in children and adolescents were included. Studies assessing food insecurity using validated tools, such as the Household Food Security Survey Module (HFSSM), were prioritized. Subgroup analyses were conducted to explore potential sources of heterogeneity.
Results: Twenty-five studies comprising 87,027 individuals were included. Household food insecurity was significantly associated with increased odds of anemia in both younger children (0-5 years) (OR = 1.32; 95% CI: 1.13, 1.53) and older children/adolescents (6-18 years) (OR = 1.67; 95% CI: 1.16, 1.83). Subgroup analyses suggested that food insecurity severity and geographic region influenced the strength of this association.
Conclusions: This study provides robust evidence that household food insecurity is associated with an increased risk of anemia in children and adolescents. Addressing food insecurity is critical to mitigating anemia risk, particularly among vulnerable populations. Future research should further explore how different measures of food insecurity, including child-specific food insecurity, impact anemia risk to inform targeted interventions.
