1. Prevalence of Food Insecurity

1.1 By race/ethnicity

1.2 By poverty level

1.3 By Child Disability Status

1.4 By Single Parent Status

2. Association Between Food Insecurity & Mental Health

2.1 Caregivers’ Mental Health

2.2 Child Mental Health

2.3 Chain of Hardship Effect

Mediation Analyses: Food Insecurity -> Caregivers’ Mental Health -> Children’s Mental Health

Path c (direct effect): food insecurity -> children’s mental health problems at second subsequent response

  • Food insecurity significantly predicted increased total mental health problems among children during the second subsequent response(b = 1.36, p < .001), controlling for the current total mental health problems score (b = .62, p < .001)
