METHODS: We performed a systematic review that examined household food insecurity among the undernourished under-five children. PubMed, Cochrane, EBSCO Host, Web of Science and Cumulative Index to Nursing and Allied Health Literature were searched from 1 January 2012 to 1 April 2022, for relevant articles. Outcome measures were stunting, underweight or wasting. Of the 2779 abstracts screened, 36 studies that fulfilled the inclusion and exclusion criteria were included. A range of tools had been used to measure HFIS, the most common being Household Food Insecurity Access Scale. HFIS has been found to be significantly associated with undernutrition, particularly stunting and underweight. This is observed proportionately across all national income levels.
CONCLUSIONS: Sustainable and inclusive economic growth, which aims to reduce income, education and gender inequality, should be a key policy goal in the minimizing food insecurity and childhood undernutrition. Multisectoral interventions are needed to address these issues.
