CNN article cites research done by Curry's Anna Markowitz in article discussing nutrition and school performance.
Children who experienced food insecurity during infancy and toddlerhood had lower cognitive and social-emotional skills in kindergarten compared with peers who had enough nutritious food during their earliest stages of development, said Anna Johnson, lead author of the new study and an assistant professor of psychology at Georgetown University. 'Food insecurity' is a term used by the USDA to describe households in which residents lack adequate access to food.
When food insecurity occurred in the preschool years, it also had a negative impact on school performance, said Johnson and her co-author, Anna Markowitz, a postdoctoral research associate at the University of Virginia. Johnson and Markowitz investigated 3,700 low-income households for their study.
However, the effects of food insecurity during preschool appeared to less consistently impact kindergarten performance than did hunger at an earlier age.
Yet how often food insecurity happened mattered. Three episodes of food insecurity versus one or two was linked to poorer outcomes in kindergarten across all areas of development, Johnson and Markowitz said.
