Abstract

Abstract : Limited access to nutritious food during infancy and early childhood is linked to health problems including obesity, anemia, low birth weight, poor child health and chronic stress. Abstract: Food insecurity, or limited access to nutritious foods, is a significant public health concern especially among vulnerable populations including infants and young children in low-income households. While literature to date has thoroughly examined the psychological and behavioral impacts of food insecurity on children, no known study to date has specifically synthesized the literature exploring the relationship between food insecurity and physiological health outcomes during early childhood. The purpose of this study was to review the literature on physiological health outcomes associated with food insecurity during early childhood among children aged 0–5 years in developed countries. Our literature search sources included PubMed, PsycInfo, CINAHL, and Embase databases. A total of 657 articles published up to September 2019 were reviewed for eligibility by two coders, with a third reviewer in cases of disagreement. Eighty-three articles remained after screening by abstract, with a final 27 studies ultimately included in the final synthesis. This review is registered with PROSPERO and adhered to PRISMA guidelines. In total, 20 articles (74%) noted significant relationships between food insecurity and physiological health outcomes in young children. Findings included an association with overweight or obesity ( n = 9), anemia ( n = 3), poor child health ( n = 3), low birth weight ( n = 3), chronic illness ( n = 1), special health care needs ( n = 1), and increased cortisol ( n = 1), in young children who experience food insecurity. Identifying relationships between food insecurity and health outcomes during early childhood has the potential to inform future prevention interventions to reduce health disparities in these vulnerable populations.
