Abstract
Food insecurity has been identified as an important social determinant of health and is associated with many health issues prevalent in Medicaid members. Despite this, little research has been done around food insecurity within Medicaid populations.
Our objective was to estimate the prevalence of household food insecurity and identify factors associated with experiencing food insecurity in Iowa's Medicaid expansion population.
We conducted a cross-sectional telephone survey between March and May of 2019.
Our sample was drawn from Medicaid members enrolled in Iowa's expansion program at least 14 months, stratified by Federal Poverty Level (FPL) category. Members who did not have valid contact information were excluded. We selected one individual per household to reduce the interrelatedness of responses. We sampled 6,000 individuals and had 1,349 respondents in the analytic sample.
Our main outcome was whether a respondent's household experienced food insecurity in the previous year, using the Hunger Vital Sign screening tool.
We weighted responses to account for the sampling design and differential nonresponse between strata. We estimated the prevalence of food insecurity and used logistic regression to model food insecurity as a function of demographic (age, FPL category, gender, employment, education, race, rurality, and Supplemental Nutrition Assistance Program [SNAP] participation) and health-related (self-rated health, self-rated oral health, health literacy) factors.
The estimated prevalence of experiencing food insecurity was 51.3%. Race, gender, education, employment, health literacy, and self-rated health were all significantly associated with food insecurity.
Our findings show that food insecurity is prevalent in Iowa's Medicaid expansion population. Food insecurity should be more widely measured as a critical social determinant of health in Medicaid populations. Policymakers and clinicians should consider interventions that connect households experiencing food insecurity to food resources (eg, produce prescriptions and food pantry referrals) and policies that increase food access.
