Food Security Status and Hair Cortisol among Low-income Mother-Child Dyads.

This cross-sectional study among low-income mother-child dyads examined the relationship between food security status and hair cortisol concentration (HCC), and how mother and child food security status was interactively related to mothers' perceived distress and coping. Data from 32 dyads were analyzed. Approximately 46.9% had household food insecurity, 37.5% children had food insecurity, and 34.4% mothers had food insecurity. Children with food insecurity had significantly higher HCC than those with food security. A significant interaction effect occurred between child food security status and race on children's HCC, with White children's HCC being more likely to be influenced by food security status. Mother food security and child food security status together explained about 6% of the variance in mothers' HCC, 27% in perceived distress, and 18% in perceived coping. These findings indicate that assisting low-income families with food insecurity to get enough food can benefit both children's and mothers' mental health.
