Objectives: Food insecurity (FI) may impair cognitive function through multiple pathways. The study aims to systematically review the current evidence of the association between FI and cognitive function in adult population.
Methods: A systematic review of the of literature published between January 1995 and December 2017 (in PubMed) on FI and cognitive function in human subjects was conducted by three independent reviewers (NJ, JH, and DX) .
Results: Nine studies, published between 2009 -2017, were identified that reported the association between FI and cognitive function, including 7 cross-sectional and 2 cohort studies. In 8 studies that reported FI in relation to global cognitive function, seven found that FI was associated with poorer cognitive test performance and one study reported a null relationship. FI was also associated with poorer executive function and memory in 4 studies where specific cognitive functions were examined. The 2 cohort studies generated mixed results: one study found that early-life exposure to FI was associated with a slower rate of global cognitive decline among African Americans; the other found that mid-life exposure to FI was associated with faster decline in global and executive function decline among Puerto Ricans in the US.
Conclusions: Despite the still-sparse data, there is emerging evidence suggesting that FI may contribute to poor cognitive functions in adult populations. However, data were not sufficient to conclude that there is a longitudinal relationship between FI and cognitive function. More longitudinal studies are needed to both confirm the association and clarify the direction of causality.
