Impact of Housing Instability and Social Risk Factors on Food Insecurity Among Vulnerable Residents in San Diego County.

To analyze the impact of housing instability and social risk facts on food insecurity using resource center client information. We utilized 2-1-1 San Diego's client database to analyze the association of food insecurity and housing instability among residents from August 2017 to March 2020. 3468 clients had food or housing needs assessed by a risk rating scale. A multiple logistic regression model analyzed the associations between food insecurity and social risk factors including housing, transportation, utility bills, criminal justice, and medical debt. Multiple logistic regression indicates that those with housing instability encounter significantly greater risk of food insecurity (AOR 1.2) for homeless-sheltered, (AOR 2.1) for homeless-unsheltered. Also, utility needs (AOR 1.2) is significantly associated with food insecurity. However, those with medical debt are 48% less likely to have food insecurity. Approximately 77% of clients experienced food insecurity. Those with food insecurity also experienced higher needs in housing and other social risk factors. By further researching the association of food insecurity, housing instability, and other social needs in a population, we can better inform public health strategies that focus on proactive community and resource planning.
