Food Insecurity and Stress Among Rural Residents in South Carolina: The Moderating Influences of Household Characteristics, Neighborhood Social Environment and Food Environment.

Abstract

Food insecurity is linked with poor physical and mental health outcomes, including anxiety, depression and stress. Rural residents in particular face unique challenges obtaining healthy food; the COVID-19 pandemic exacerbated the relationship between food insecurity and mental health outcomes. This study examines the relationship between food insecurity and stress, and the moderating influence of household characteristics, neighborhood social environment and food environment on this relationship, using a sample of 630 rural South Carolina (SC) residents during COVID-19. Two measures of stress were used in this study: current levels of stress and changes in stress since COVID-19. Results showed a gradient pattern between food insecurity and stress: rural residents with high food insecurity were 6.1 times more likely and those with moderate food insecurity were 3.4 times more likely to report higher level of general stress than those with low food insecurity; rural residents with high food insecurity were 3.3 times more likely and those with moderate food insecurity were 2.0 times more likely to report greater increase in stress after COVID-19 than those with low food insecurity. Neighborhood social environment and food environment provided a buffering effect on the relationship between food insecurity and stress. A stronger social environment after COVID-19 and higher levels of easiness in food access mitigated the negative impacts of food insecurity on stress. Efforts to ameliorate food insecurity should address these broader contextual variables, involving community-level factors.
