Importance In the US, children in food-insecure households are at risk for adverse psychological outcomes despite being shielded from hunger and malnutrition by their caregivers and school- and community-based programs. Parenting stress may be an important mechanism through which food insecurity is associated with negative outcomes for child mental health. Objective To investigate associations of household food insecurity with child mental health, parenting stress, and family functioning. Design, Setting, and Participants This cross-sectional study used a daily-diary design in a community-based sample to examine associations between daily fluctuations in food insecurity and child and family functioning. The study was conducted remotely during the COVID-19 pandemic in the rural (defined by the Health Resource Services Administration) Northeastern US. Caregivers of school-aged children were enrolled during the 2021 school year and completed a baseline visit followed by mobile surveys for 30 days. Participants were adult, legal caregivers of children ages 6 to 12 years who experienced food insecurity within the past month. Participants were required to have English proficiency and access to a device with internet and texting capabilities. Prospective participants completed an online questionnaire to determine eligibility. A total of 553 respondents were screened, of which 327 respondents (59.1%) met all inclusion criteria. The most common reason for ineligibility was not having a child in the study age range. Data analyses were performed between May 2022 and April 2023. Exposure Household food insecurity. Main Outcomes and Measures The primary outcomes were caregiver hunger, negative affect, executive functioning, and parent-child interactions (measured via a daily self-report survey) and child mental health problems (measured via the Child Behavior Checklist CBCL). Results Among 61 caregivers (mean SD age, 36.1 5.9 years; 51 women 83.6%; 2 American Indian or Alaska Native 3.3%, 1 Black 1.6%, and 55 non-Hispanic White 90.2%), greater day-to-day fluctuations in household and child food insecurity were associated with more severe child internalizing problems (CBCL Internalizing Problems scale: β = 0.40; P = .003 for household and β = 0.49; P lt; .001 for child food insecurity) and total mental health problems (CBCL Total Problems scale: β = 0.34; P = .01 for household and β = 0.35; P = .01 for child food insecurity). Additionally, the daily association between food insecurity and parent-child conflict was fully mediated via 2 sequential pathways of caregiver hunger and negative affect ( b = .02; P = .001) and caregiver hunger and attention and impulse control ( b = 0.01; P = .04). This model explained 17% of variability in daily parent-child conflict ( R 2 = 0.17). Conclusions and Relevance This study’s findings suggest that caregiver stress and household instability may be key mechanisms by which food insecurity is negatively associated with child mental health.
