Reducing food insecurity and improving fruit and vegetable intake through a nutrition incentive program in Michigan, USA

U.S. food policy to address diet-related chronic disease

Poor diet is the leading cause of mortality in the U.S. due to the direct relationship with diet-related chronic diseases, disproportionally affects underserved communities, and exacerbates health disparities. Evidence-based policy solutions are greatly needed to foster an equitable and climate-smart food system that improves health, nutrition and reduces chronic disease healthcare costs. To directly address epidemic levels of U.S. diet-related chronic diseases and nutritional health disparities, we conducted a policy analysis, prioritized policy options and implementation strategies, and issued final recommendations for bipartisan consideration in the 2023-24 Farm Bill Reauthorization. Actional recommendations include: sugar-sweetened beverage taxation, Supplemental Nutrition Assistance Program (SNAP) fruit and vegetable subsidy expansion, replacement of ultra-processed foods (UPF) with sustainable, diverse, climate-smart agriculture and food purchasing options, and implementing "food is medicine."

Associations between food insecurity and diabetes risk factors in US adolescents in the National Health and Nutrition Examination Survey (NHANES) 2007-2016

OBJECTIVE

To evaluate the associations between household food insecurity and diabetes risk factors among lower-income US adolescents.

DESIGN

Cross-sectional analysis. Household food security status was measured using the 18-item Food Security Survey Module. Simple and multivariable linear and logistic regressions were used to assess the association between food security status and fasting plasma glucose (FPG), oral glucose tolerance test (OGTT), HbA1C and homoeostatic model assessment - insulin resistance (HOMA-IR). The analyses were adjusted for household and adolescent demographic and health characteristics.

SETTING

USA.

PARTICIPANTS

3412 US adolescents aged 12-19 years with household incomes ≤300 % of the federal poverty line from the National Health and Nutrition Examination Survey cycles 2007-2016.

RESULTS

The weighted prevalence of marginal food security was 15·4 % and of food insecurity was 32·9 %. After multivariate adjustment, adolescents with food insecurity had a 0·04 % higher HbA1C (95 % CI 0·00, 0·09, P-value = 0·04) than adolescents with food security. There was also a significant overall trend between severity of food insecurity and higher HbA1C (Ptrend = 0·045). There were no significant mean differences in adolescents' FPG, OGTT or HOMA-IR by household food security.

CONCLUSIONS

Food insecurity was associated with slightly higher HbA1c in a 10-year sample of lower-income US adolescents aged 12-19 years; however, other associations with diabetes risk factors were not significant. Overall, this suggests slight evidence for an association between food insecurity and diabetes risk in US adolescents. Further investigation is warranted to examine this association over time.

Which Program Implementation Factors Lead to more Fruit and Vegetable Purchases? An Exploratory Analysis of Nutrition Incentive Programs across the United States

Background

Nutrition incentive (NI) programs help low-income households better afford fruits and vegetables (FVs) by providing incentives to spend on FVs (e.g., spend $10 to receive an additional $10 for FVs). NI programs are heterogeneous in programmatic implementation and operate in food retail outlets, including brick-and-mortar and farm-direct sites.

Objective

This study aimed to explore NI program implementation factors and the amount of incentives redeemed.

Methods

A total of 28 NI projects across the United States including 487 brick-and-mortar and 1078 farm-direct sites reported data between 2020 and 2021. Descriptive statistics and linear regression analyses (outcome: incentives redeemed) were applied.

Results

Traditional brick-and-mortar stores had 0.48 times the incentives redeemed compared with small brick-and-mortar stores. At brick-and-mortar sites, automatic discounts had 3.47 times the incentives redeemed compared with physical discounts; and auxiliary services and marketing led to greater redemption. Farm-direct sites using multilingual and direct promotional marketing had greater incentives redeemed.

Conclusions

To our knowledge, this is the first national study to focus on NI program implementation across sites nationwide. Factors identified can help inform future programming and research.

Family Food Insecurity, Food Acquisition, and Eating Behavior Over 6 Months Into the COVID-19 Pandemic

OBJECTIVES

Describe coronavirus disease 2019 (COVID-19)-related employment and food acquisition changes for food-secure and food-insecure households. Examine associations between food insecurity, parent food acquisition, and child eating.

METHODS

A nationally representative cross-sectional survey with parents (N = 1,000) in Fall 2020. Measures included sociodemographics, food retail regulations, food insecurity, frequency of meals, changes in parent employment, food preparation, and food acquisition because of COVID-19.

RESULTS

Parents that reported recent food insecurity were more likely to report COVID-19-related employment changes (eg, job loss, reduced hours) and food acquisition changes. Food insecurity was modestly associated with more frequent in-person restaurant dining (B = 0.12, t(999) = 4.02, P < 0.001), more frequent restaurant delivery (B = 0.13, t(999) = 4.30, P < 0.001), less frequent homecooked meals (B = -0.14, t(999) = 4.56, P < 0.001) but was not associated with take-out (B = 0.02, t(999) = 0.62, P = 0.54).

CONCLUSIONS AND IMPLICATIONS

Food insecurity was associated with employment changes, parent food acquisition, and children's consumption of homecooked and restaurant meals during COVID-19. Future work could explore resources that help parents acquire affordable, nutritious food.

Understanding Impacts of SNAP Fruit and Vegetable Incentive Program at Farmers' Markets: Findings from a 13 State RCT

Disparities in healthy food access and consumption are a major public health concern. This study reports the findings from a two-year randomized control trial conducted at 77 farmers' markets (FMs) in 13 states and the District of Columbia that sought to understand the impact of fruit and vegetable (FV) incentive vouchers, randomly issued at varied incentive levels to Supplemental Nutrition Assistance Program (SNAP) recipients, for use at FMs. Measures included FV and overall household food purchasing; FV consumption; food insecurity; health status; market expenditure; and demographics. A repeated-measures mixed-effects analysis and the Complier Average Causal Effect (CACE) were used to examine outcomes. Despite 82% reporting food insecurity in the prior year, the findings showed that financial incentives at FMs had statistically significant, positive effects on FV consumption; market expenditures increased with added incentives. SNAP recipients receiving an incentive of USD 0.40 for every USD 1.00 in SNAP spent an average of USD 19.03 per transaction, while those receiving USD 2 for every USD 1 (2:1) spent an average of USD 36.28 per transaction. The data showed that the incentive program at the highest level (2:1) maximally increased SNAP FM expenditure and FV consumption, increasing the latter by 0.31 daily cups among those who used their incentive (CACE model).

How Does the Gus Schumacher Nutrition Incentive Program Work? A Theory of Change

Increased fruit and vegetable (FV) intake is associated with decreased risk of nutrition-related chronic diseases. Sociodemographic disparities in FV intake indicate the need for strategies that promote equitable access to FVs. The United States Department of Agriculture’s Gus Schumacher Nutrition Incentive Program (GusNIP) supports state and local programs that offer nutrition incentives (NIs) that subsidize purchase of FVs for people participating in the Supplemental Nutrition Assistance Program (SNAP). While a growing body of research indicates NIs are effective, the pathways through which GusNIP achieves its results have not been adequately described. We used an equity-focused, participatory process to develop a retrospective Theory of Change (TOC) to address this gap. We reviewed key program documents; conducted a targeted NI literature review; and engaged GusNIP partners, practitioners, and participants through interviews, workshops, and focus groups in TOC development. The resulting TOC describes how GusNIP achieves its long-term outcomes of increased participant FV purchases and intake and food security and community economic benefits. GusNIP provides NIs and promotes their use, helps local food retailers develop the capacity to sell FVs and accept NIs in accessible and welcoming venues, and supports local farmers to supply FVs to food retailers. The TOC is a framework for understanding how GusNIP works and a tool for improving and expanding the program.
