Associations between daily food insecurity and parent and child well-being.

Food insecurity poses a serious threat to children's development, but the mechanisms through which food insecurity undermines child development are far less clear. Specifically, food insecurity may influence children through its effect on parents' psychological well-being and parent-child interactions as a result, but past research on the role of parents is correlational and undermined by omitted variable bias. Using a partially rural, low-income sample of parents living in Pennsylvania ( = 272, 90% mother, = 35) and their school-aged children (ages 4-11, 50% female) alongside daily measures of parent-reported food insecurity and parent and child mood and behavior, we examine how daily changes in food insecurity predict daily changes in parent and child well-being, and the extent to which food insecurity operates through parents to affect children. This method not only explores families' daily, lived experiences of food insecurity, but improves upon the methodological issues undermining past research. Findings indicate that food insecurity influences parent and child well-being on a daily basis, but that associations are stronger and sustain longer for parents than children. Further, parent mood and behavior partially explain the association between daily food insecurity and child mood and behavior, but food insecurity is also independently associated with child well-being. This study is the first to examine daily associations between food insecurity and parent and child well-being. Its implications for food assistance programs, policies, and the future of food insecurity research are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
