Development and testing of the FRESH Foods Survey to assess food pantry clients' dietary behaviours and correlates

Benefits of using both the Hunger Vital Sign and brief nutrition security screener in health-related social needs screening

Food security is a commonly screened for health-related social need at hospitals and community settings, and until recently, there were no tools to additionally screen for nutrition security. The purpose of this study was to assess the potential advantage of including a one-item brief nutrition security screener (BNSS) alongside the commonly used two-item Hunger Vital Sign (HVS) food security screener for identifying individuals with diet-related health risks. Cross-sectional survey data were collected from April to June 2021. Generalized linear mixed models were used to assess associations between screening status and dietary and health variables. Recruitment was done across five states (California, Florida, Maryland, North Carolina, and Washington) from community-based organizations. Participants (n = 435) were, on average, 44.7 years old (SD = 14.5), predominantly women (77%), and racially/ethnically diverse. In adjusted analyses, being in the food insecure and nutrition insecure group (but not the food insecure and nutrition secure or food secure and nutrition insecure groups) was associated with significantly increased odds for self-reported "fair" or "poor" general health [OR = 2.914 (95% CI = 1.521-5.581)], reporting at least one chronic condition [2.028 (1.024-4.018)], and "low" fruit and vegetable intake [2.421 (1.258-4.660)], compared with the food secure and nutrition secure group. These findings support using both the HVS and BNSS simultaneously in health-related social needs screening to identify participants at the highest risk for poor dietary and health outcomes and warrant further investigation into applying these screeners to clinical and community settings.

New measures to assess the "Other" three pillars of food security-availability, utilization, and stability

BACKGROUND

In recent reviews of available measures, no existing measures assessed all four pillars of food security and most only assessed one or two pillars-predominantly the access pillar. The purpose of this study was to preliminarily develop novel measures of availability, utilization, and stability that are complementary to the USDA's household food security survey measure (HFSSM).

METHODS

A formative phase included an expert advisory group, literature scans, and interviews with individuals experiencing food insecurity. From April-June 2021, the new measures were piloted in five states (California, Florida, Maryland, North Carolina, and Washington). The cross-sectional pilot survey included the new measures (perceived limited availability, utilization barriers, and food insecurity stability), scales and items for validation (e.g., food security, and self-reported dietary and health outcomes), and demographic questions. Exploratory factor analysis was used to assess dimensionality, internal consistency was assessed using Kuder-Richardson formula 21 (KR21), and convergent and discriminant validity were assessed using Spearman's correlation coefficients. Also, a brief screener version was created for the utilization barriers measure that may be necessary for certain applications (e.g., clinical intake screening to inform referrals to assistance programs).

RESULTS

The analytic samples (perceived limited availability (n = 334); utilization barriers (n = 428); food insecurity stability (n = 445)) were around 45 years old on average, most households had children, over two-thirds were food insecure, over three-fourths were women, and the samples were racially/ethnically diverse. All items loaded highly and unambiguously to a factor (factor loadings range 0.525-0.903). Food insecurity stability showed a four-factor structure, utilization barriers showed a two-factor structure, and perceived limited availability showed a two-factor structure. KR21 metrics ranged from 0.72 to 0.84. Higher scores for the new measures were generally associated with increased food insecurity (rhos = 0.248-0.497), except for one of the food insecurity stability scores. Also, several of the measures were associated with statistically significantly worse health and dietary outcomes.

CONCLUSIONS

The findings support the reliability and construct validity of these new measures within a largely low-income and food insecure sample of households in the United States. Following further testing, such as Confirmatory Factor Analysis in future samples, these measures may be used in various applications to promote a more comprehensive understanding of the food insecurity experience. Such work can help inform novel intervention approaches to address food insecurity more fully.

The impact of medically tailored meals and nutrition therapy on biometric and dietary outcomes among food-insecure patients with congestive heart failure: a matched cohort study

Background

To evaluate the impact of home-delivered, medically tailored meals and medical nutrition therapy among food-insecure patients following hospitalization for congestive heart failure by comparing clinical outcomes to a retrospectively matched cohort.

Methods

Patients at high risk for readmission and food insecurity received up to three months of medically tailored meals and medical nutrition therapy after discharge. Pre-intervention and post-intervention weight, body mass index, blood pressure, and dietary intake were assessed. A combination of difference-in-difference and logistic regression models were used to compare changes between cohorts and evaluate impact attributable to the program.

Results

Thirty-nine program participants were compared to a matched cohort of 117 unexposed patients. Participants experienced a marginal reduction in body mass index and an increase in systolic and diastolic blood pressure; however, these results were not statistically significant. To determine relevance to clinical cut-offs, logistic regressions were used, demonstrating that exposure to the intervention resulted in higher odds of a categorical reduction in blood pressure (OR: 1.85), though this did not reach statistical significance (95% CI: 0.67–5.32). Pre vs. post trends indicated that more-healthful foods and drinks increased numerically or remained similar to baseline, while less-healthful foods decreased numerically or remained similar to baseline.

Conclusions and implications

These findings highlight the need for more longitudinal research on medically tailored meals and medical nutrition therapy interventions using clinical outcomes while setting realistic suggestions for program implementation. This study additionally illustrates the promise of integrating electronic medical record data and matched cohorts into medical nutrition program evaluation within the health sector.

Disparities in dietary practices during the COVID-19 pandemic by food security status

Little is known about the differences in dietary practices among food secure and food insecure populations during the early COVID-19 pandemic restrictions. The purpose of this study was to examine differences in dietary practices the early COVID-19 pandemic restrictions between adults reporting food security versus food insecurity. An online cross-sectional survey using validated measures was administered between April and September 2020 to explore both dietary patterns and practices and food security status among persons residing in five U.S. states from different regions of the country during the COVID-19 pandemic. Between-group differences (food secure versus food insecure) were examined for dietary practice outcomes using Pearson's Chi-Square test statistic, with Fisher's Exact test for cell counts less than five. There were 3,213 adult respondents. Food insecurity increased among the survey sample from 15.9% before the COVID-19 pandemic to 23.1% during the onset of the COVID-19 pandemic (p < 0.01). Compared to food secure respondents, those experiencing food insecurity reported more group gatherings for meals during the pandemic, decreased fruit and vegetable intake, and a need for more nutrition support resources than food secure respondents (p < 0.05). Food secure individuals reported increasing alcohol consumption, more frequent take-out or delivery ordering from fast food or restaurants, and more interest in supporting the local food system (p < 0.05). Results indicate a clear risk of disparities in dietary practices based on food security status during the early COVID-19 pandemic restrictions. Public health research, practice, and policy efforts should tailor specific efforts towards both food secure and food insecure groups.

The UnProcessed Pantry Project (UP3): A Community-Based Intervention Aimed to Reduce Ultra-Processed Food Intake Among Food Pantry Clients

Low-income populations are more likely to experience food and nutrition insecurity and suffer a greater burden of noncommunicable disease than the general population. The UnProcessed Pantry Project (UP3) is an intervention aimed to reduce ultra-processed food availability and consumption of food pantry clients accessing the emergency food system. The pilot study included nutrition education, food boxes, and social support for 16 weeks at 2 food pantries. Data collection included the ASA24 dietary recall to calculate Healthy Eating Index-2015 (HEI-2015) scores, biomarkers (hemoglobin A1c, total cholesterol, blood pressure, waist circumference, body mass index [BMI]), and a demographic and psychosocial survey. Dietary quality among 43 participants significantly (P < .05) improved as measured by the HEI-2015 for total HEI-2015, whole grains, total protein foods, and added sugars scores. BMI, total cholesterol, and waist circumference also significantly improved across study participants. Findings indicate that the emergency food system may be an effective access point to apply frameworks including UP3 to address ultra-processed food consumption, dietary quality, and noncommunicable chronic disease risk among food-insecure populations. Programs and policies that limit the amount of ultra-processed food in the emergency food system should be further tested and could be efficacious in addressing inequities among vulnerable populations.

Exploring the Lived Experience of Food Insecure African Americans with Type 2 Diabetes Living in the Inner City

Purpose

Despite evidence that food insecure African Americans with type 2 diabetes are at particularly high risk for poor health outcomes, there is currently a lack of information on their lived experience. This qualitative study aimed to identify challenges, facilitators, and barriers to effective diabetes care for food insecure African Americans with type 2 diabetes residing in an inner city.

Methods

In fall 2018, we conducted two focus groups attended by a total of 16 food insecure adults with type 2 diabetes residing in the inner city of Milwaukee, Wisconsin. A standardized moderator guide included questions to explore the role of food insecurity in managing diabetes, and facilitators that improve diabetes management within the context of food insecurity. Focus groups were audio recorded and recordings were transcribed by a professional transcription service. A grounded theory approach was used for analysis.

Results

Six major challenges existed at the individual level (diet/nutrition, exercise, diabetes knowledge and skills, complications from diabetes, a family history of diabetes, and a preoccupation with food). Five major barriers and facilitators existed both internally and externally to the individuals (access to food, medications, stress, cost of health-related needs and religion/spirituality).

Conclusions

This study identified multiple challenges, barriers, and facilitators to effective care for food insecure African American adults with type 2 diabetes. It is imperative to incorporate this understanding in future work by using an ecological approach to investigate strategies to address food insecurity beyond a singular focus on access to food.

Food Bank-Based Diabetes Prevention Intervention to Address Food Security, Dietary Intake, and Physical Activity in a Food-Insecure Cohort at High Risk for Diabetes

Purpose and Objectives

Although food insecurity is associated with poor dietary intake and risk of chronic disease, few studies have demonstrated the effectiveness of diabetes prevention interventions delivered through food banks. Food banks serve vulnerable communities. The purpose of this pilot project was to assess the effectiveness of a food bank–delivered intervention aimed at improving food security and reducing risk factors for type 2 diabetes among at-risk clients.

Intervention Approach

We screened adult English- and Spanish-speaking food bank clients for type 2 diabetes risk at 12 community food distribution sites in Alameda County, California. Screening and enrollment for a pilot intervention took place from November 2017 to March 2018. Intervention components were delivered from November 2017 through March 2019. The intervention included monthly diabetes-appropriate food packages, text-based health education, and referrals to health care.

Evaluation Methods

Food bank staff members administered surveys to participants at baseline, 6 months (midpoint), and 12 months (postintervention); participants self-reported all responses. Primary outcomes assessed were food security status, dietary intake, health-related behaviors, and body mass index (BMI). Information on demographic characteristics, food pantry access, health care use, and symptoms of depression was also collected.

Results

We screened 462 food bank clients for eligibility. Of the 299 who were eligible, 244 enrolled; 90.6% were female, 80.1% were Hispanic, and 49.1% had an annual household income less than $20,000. At baseline, 68.8% of participants had low or very low food security. At midpoint, participants had significant improvements in food security status, dietary intake, physical activity, health status, and depression scores. Mean BMI did not change.

Implications for Public Health

This intervention demonstrated that food banks can effectively screen clients at high risk for diabetes and improve household food security and other risk factors for diabetes. Food banks may be an important and strategic partner for health care systems or community-based organizations working to prevent diabetes in food-insecure populations.
