Studies on the relationship between food insecurity and malnutrition in pediatric population in the United States have yielded inconsistent results, with some showing no clear relationship between food insecurity and underweight, while large cross-sectional studies demonstrating a positive relationship between food insecurity and overweight/obesity. There were no clear patterns based on subpopulation.
Both food insecurity and malnutrition are associated with adverse health outcomes in the pediatric population. However, the research on the relationship between these factors has been inconsistent, leading to uncertainty regarding whether or how evaluation of food insecurity should be incorporated into nutrition screening or the nutrition care process. The objective of this systematic review was to determine the association between food insecurity and malnutrition related to undernutrition or overnutrition (defined by anthropometrics) in the pediatric population in the United States. A literature search was conducted using Medline, Embase, and CINAHL databases for studies published from January 2002 through November 2017. A total of 23 studies (19 cross-sectional and 4 prospective cohort studies) met inclusion criteria and were included in qualitative analysis. In 6 studies, there was no overall relationship between food insecurity and underweight. All included studies examined the relationship between food insecurity status and overweight/obesity and results were mixed, with large cross-sectional studies demonstrating a positive relationship between food insecurity and overweight/obesity. There were no clear patterns according to subpopulation. Evidence quality was graded as fair due to heterogeneity in how food insecurity was measured and populations included as well as inconsistency in results. Use of a 2-item food insecurity screening tool may allow for efficient, effective screening of food insecurity in order to identify potential contributors overweight and obesity.
