Household Food Insecurity and Children’s Physical Activity and Sedentary Behavior in the United States: The Healthy Communities Study
Abstract Objective: To examine associations between household food insecurity and children’s physical activity and sedentary behaviors. Design: Secondary analysis was conducted on the Healthy Communities Study, an observational study from 2013-2015. Household food insecurity was assessed by two items from the US Department of Agriculture’s 18-item US Household Food Security Survey Module. Physical activity was measured using the 7-day Physical Activity Behavior Recall instrument. Data were analyzed using multilevel statistical modeling. Setting: 130 communities in the US. Participants: 5,138 US children ages 4-15 years. Results: No associations were found for the relationship between household food insecurity and child physical activity. A significant interaction between household food insecurity and child sex for sedentary behaviors was observed (P=0.03). Conclusions: Additional research capturing a more detailed assessment of children’s experiences of food insecurity in relation to physical activity is warranted. Future studies may consider adopting qualitative study designs or utilizing food insecurity measures that specifically target child-level food insecurity. Subsequent research may also seek to further explore sub-group analyses by sex.
