Household food insecurity and children's physical activity and sedentary behaviour in the United States: the Healthy Communities Study.
Published Web Locationhttps://doi.org/10.1017/s1368980021002536
ObjectiveTo examine associations between household food insecurity and children's physical activity and sedentary behaviours.
DesignSecondary analysis was conducted on the Healthy Communities Study, an observational study from 2013 to 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-d Physical Activity Behaviour Recall instrument. Data were analysed using multilevel statistical modelling.
SettingA total of 130 communities in the USA.
ParticipantsIn sum, 5138 US children aged 4-15 years.
ResultsNo 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 behaviours was observed (P = 0·03).
ConclusionsAdditional 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 utilising food insecurity measures that specifically target child-level food insecurity. Subsequent research may also seek to further explore sub-group analyses by sex.
