Exploring Sociodemographic and Chronic Disease Factors Associated With Chronic, Seasonal, Intramonthly, and Intermittent Presentations of Food Security Instability

Background Food insecurity impacts 13.5 million US households yearly. Although food security instability (FS-I) can have many temporal presentations, these are not measured in the current US Household Food Security Survey Module. Objective Explore sociodemographic and chronic disease correlates of 4 FS-I types (chronic, seasonal, intramonthly, and intermittent) using a 3-item US Household Food Security Survey Module instability supplement. Design This study was a secondary analysis of cross-sectional survey pilot data collected to validate the US Household Food Security Survey Module instability supplement. Participants and setting Adults at risk for food insecurity (n = 420) were recruited and answered the survey on their households' behalf from April to June 2021. The participants were recruited from 7 community organizations from 5 states (California, Florida, Maryland, North Carolina, and Washington). Main outcome measures The main outcomes were the odds of having a chronic, seasonal, intramonthly, or intermittent FS-I score >= 1 based on several sociodemographic factors and having >= 1 chronic disease. Statistical analyses performed Differences among the 4 FS-I types were analyzed using contingency tables and c2 2 tests of independence. Then, mixed-effects logistic binary and conditional regressions were run for each FS-I type using clustering by state and odds ratios and 95% CI to interpret results. Results The most common FS-I type experienced by the sample was intramonthly (n = 183 [43%]). Nonchronic food insecurity was most likely to happen during the winter, at the end of the month, or randomly with no certain time frame. FS-I in any form was associated with low income, chronic FS-I was associated with younger age and male sex, seasonal FS-I was associated with having no government-subsidized health insurance and females, intramonthly FS-I was associated with participation in nutrition assistance programs, and intermittent FS-I had lower odds among Hispanic/Latino households. Conclusions Further research is needed to explore other FS-I correlates and establish causative relationships; however, these results can be used with clinical judgment for targeted food insecurity screening and treatment.
