    Medical Debt and Hunger-Coping Economic Tradeoffs Among Charitable Food Assistance Clients

    by Maha Almohamad, Crystal Cartwright, Fred P. Brooks, Craig Gundersen, Daphne C. Hernandez

    Objective: Medical debt is a long-term hardship, typically unplanned, and difficult to resolve. Hunger-coping economic tradeoffs (e.g., choosing between food or another basic need) are smaller financial constraints related to implementing short-term strategies to resolve cash shortages. This study examined associations between long-term financial constraint (medical debt) and engagement in short-term financial strategies (hunger-coping economic tradeoffs) among charitable food assistance (CFA) recipients. Methods: Survey data were collected in 10 Houston-area and 10 Atlanta-area food pantries in 2022. Hunger-coping economic tradeoff experiences were based on affirmative responses to whether anyone in the household ever had to choose between food and five basic needs. Covariate-adjusted logistic regression models were used to assess the relationship between medical debt (defined as unpaid medical bills) and each hunger-coping tradeoff. Results: Among 999 participants (mean age, 55 years), 41% reported medical debt. Participants with medical debt had greater odds of having to choose between paying for food or (1) childcare (AOR = 1.92, 95% CI 1.37–2.69, p < 0.001), (2) utilities (AOR = 2.05, 95% CI 1.59–2.64, p < 0.001), (3) rent/mortgage (AOR = 2.34, 95% CI 1.75–3.14, p < 0.001), (4) transportation/gas (AOR = 2.81, 95% CI 2.05–3.85, p < 0.001), and (5) education (AOR = 2.18, 95% CI 1.42–3.34, p < 0.001). Conclusions: Long-term hardship (i.e., medical debt) was associated with CFA recipients reporting engaging in short-term financial strategies (i.e., hunger-coping economic tradeoffs) to make ends meet. These findings highlight the need to screen CFA recipients for medical debt, economic hardship, and financial management skills, with food pantries serving as key referral points.

    When Access Is Not Enough: The Role of Utilization Barriers in Nutrition Security and Cardiometabolic Risk

    by Maha Almohamad, Ruosha Li, Natalia I. Heredia, Jayna M. Dave, Eric E. Calloway, Anjail Z. Sharrief, Shreela V. Sharma

    Background: Food and nutrition security are key social determinants of cardiometabolic health. While food security reflects access to sufficient food, nutrition security incorporates the quality, consistency, and usability of food that supports long-term health. However, few studies have examined how household-level barriers to food utilization shape these relationships. Objective: This study assessed whether tangible (e.g., equipment, storage) and intangible (e.g., time, knowledge) food utilization barriers modify the associations between food and nutrition security and cardiometabolic outcomes in low-income adults. Methods: A cross-sectional survey was conducted among 486 low-income adults across five U.S. states. Participants reported household food security (USDA 18-item module), nutrition security (four-item scale), and utilization barriers (eight-item scale, categorized into tangible and intangible subscales). Self-reported diagnoses of hypertension, hyperlipidemia, and diabetes were combined into a cardiometabolic outcome. Mixed-effects logistic regression models, adjusted for sociodemographic and program participation factors, were used to assess associations and effect modification. Results: Higher nutrition security was associated with lower odds of cardiometabolic conditions (AOR = 0.59; 95% CI: 0.41–0.83). Tangible barriers significantly modified the relationship between nutrition security and hypertension (p-interaction = 0.04), with stronger protective effects observed in households without such barriers. No significant moderation effects were found for intangible barriers or for food security. Conclusions: Tangible household barriers influence the protective association between nutrition security and cardiometabolic outcomes. Public health strategies should address not only food access but also the practical resources required to store, prepare, and consume healthy foods effectively.

    SNAP Participation as a Moderator of Food and Nutrition Security and Combined Cardiometabolic Conditions: A Mixed Regression Approach

    by Maha Almohamad, Ruosha Li, Natalia I. Heredia, Jayna M. Dave, Eric E. Calloway, Anjail Sharrief, Shreela V. Sharma

    Objectives: To examine the relationships between food security, nutrition security, Supplemental Nutrition Assistance Program (SNAP) participation, and cardiometabolic outcomes, including hypertension, hyperlipidemia, or diabetes, among low-income U.S. individuals. Methods: A cross-sectional survey of 486 participants (April–June 2021) assessed food and nutrition security and cardiometabolic outcomes. Mixed-effects logistic regression models adjusted for covariates and included a random effect for state of residence. Moderation analyses evaluated SNAP participation’s impact. Results: Very low food security was associated with higher odds of having at least one cardiometabolic condition, such as hypertension, hyperlipidemia, or diabetes (AOR = 1.96; 95% CI: 1.04–3.69; p = 0.04). SNAP moderated this relationship (p-interaction = 0.007), with non-participants experiencing significantly higher risk. Non-SNAP participants with very low food security had 3.17 (95% CI = 1.17–8.61) times higher odds of having a cardiometabolic condition. Among SNAP participants, very low food security was not significantly associated with having a cardiometabolic condition (OR = 1.62; 95% CI = 0.64–4.13). Higher nutrition security was associated with lower odds of having at least one cardiometabolic condition (AOR = 0.59; 95% CI: 0.41–0.83; p = 0.002). Conclusions: Nutrition security and SNAP participation mitigate cardiometabolic risks, underscoring their importance in public health interventions.

    Dietary behaviours during COVID-19 among households at risk for food insecurity

    by Maha Almohamad, Allison Marshall, Jayna Markand Dave, Ru-Jye Chuang, Christine Markham, Shreela Sharma

    The objective of the present study was to examine associations between variables of COVID-19-related concerns and changes in fruit and vegetable (FV) consumption among a sample of participants from the Brighter Bites program at risk for food insecurity. Cross-sectional data were collected during April–June 2020 using a rapid-response survey to understand social needs, COVID-19-related concerns and diet-related behaviours among families with children participating in Brighter Bites (n 1777) in the 2019–2020 school year at risk for food insecurity, within the surrounding Houston, Dallas, Austin, Texas area; Southwest Florida; Washington, D.C., United States. Of the 1777 respondents, 92 % of households reported being at risk for food insecurity. Among those from food insecure households, the majority were of Hispanic/Mexican-American/Latino (84⋅1 %) ethnic background, predominantly from Houston, Texas (71⋅4 %). During the pandemic, among individuals from food insecure households, 41 % (n 672) reported a decrease in FV intake, 32 % (n 527) reported an increase in FV intake, and 27 % (n 439) reported no change in FV intake. Those who reported concerns about financial stability had a 40 % greater risk of decreased FV intake compared to those not concerned about financial stability (RR 1⋅4; 95 % CI 1⋅0, 2⋅0; P = 0⋅03). The present study adds to this current body of sparse literature on how the initial phase of the pandemic impacted FV consumption behaviours among food insecure households with children. Effective interventions are needed to diminish the negative impact of COVID-19 on the population's health.
