Structural Determinants of Health Literacy Among Formerly Incarcerated Individuals: Insights From the Survey of Racism and Public Health.

Abstract

Background: Formerly incarcerated individuals (FIIs) encounter difficulties with covering the cost of dental and medical care, adhering to medication regimens, and receiving fair treatment from health care providers. Yet, no published research has examined modifiable pathways to increase FIIs' health literacy (HL), which is essential for addressing the health needs of this vulnerable population.

Objective: The aim of this article is to examine neighborhood characteristics (neighborhood deprivation, racial and economic polarization, and residential segregation) and public assistance program enrollment as structural determinants of limited health literacy (LHL) among FIIs.

Methods: Using a socioecological framework, we analyzed a subsample of 578 FIIs from the 2023 Survey of Racism and Public Health, an online cross-sectional survey spanning U.S. Department of Health & Human Services Regions 1, 2, and 3. HL was assessed using the Brief Health Literacy Screen. Logistic regression models estimated unadjusted and adjusted associations of LHL with neighborhood characteristics and public assistance program enrollment. Adjusted models controlled for age, race and ethnicity, gender identity, educational attainment, marital and employment status, number of children, chronic health conditions, and incarceration length.

Key results: The 578 FIIs had an average age of 46, with 42% having LHL. We observed a statistically significant association between public assistance program enrollment and LHL (unadjusted odds ratio [OR] = 2.72, 95% confidence interval [CI]: 1.87, 4.01; adjusted OR = 2.50, 95% CI: 1.62, 3.88). We found no statistically significant associations of LHL with neighborhood deprivation, racial and economic polarization, and residential segregation.

Conclusions: Our findings suggest that there may be an opportunity to develop tailored interventions for increasing HL among FIIs through public assistance programs. Dissemination of HL resources among this marginalized group can improve their self-management of chronic diseases. This is of paramount importance because FIIs must simultaneously navigate other challenges after incarceration (e.g., unstable housing).
