In 2014, 17.4 million US households were food insecure[1] — that’s 14 percent of households with limited or uncertain access to adequate food. Meanwhile, seven out of 10 deaths annually (and 86% of health care costs) are the result of chronic disease.[2] A growing body of literature illustrates how food insecurity perpetuates a cycle of poor chronic disease management and increased spending on health care. The effects are particularly acute in older Americans.
TACKLING HUNGER seeks to find and disseminate effective strategies to address food insecurity and its relationship to acute medical events in people with chronic diseases. Through cutting edge, actionable research, we intend to drive public policy change and program innovation at the federal, state, community, and institutional levels. The project focused on adults aged 50 and older with chronic disease who experience food insecurity. The project was built around three components: The Tools for Change toolbox, the Economic Burden Study, and the Exploratory Evaluation.
Reversing the Cycle of Food Insecurity and Chronic Disease in Older Americans
This conceptual framework was developed by the Tackling Hunger project as a visual overview of the negative cycle of impacts that food insecurity has on health, and the types of interventions that have the potential to reverse the cycle. Intervention intensity and dose should be considered to maximize the impact of individual interventions; alignment across interventions in a manner that is mutually reinforcing will enhance potential for reversing the cycle. The Tackling Hunger project examines components of the cycle and interventions that aim to reverse it, and offers proposals for improving health outcomes through integrated community, health care, and policy solutions.
The framework was adapted from a similar model developed by Hilary Seligman and Feeding America
TOOLS FOR CHANGE
TACKLING HUNGER has developed a set of tools, including policy briefs and guidance on Community Health Needs Assessments, designed for program practitioners, advocates, and health system leadership. The tools are meant to raise awareness of the complex issues surrounding food insecurity, chronic, disease, and health care costs and to disseminate information on programs that seek to address these problems. They can be used to inform discussions with health system leadership and policy makers on the importance and effectiveness investments that address food insecurity.
Evaluation Resources
Evaluation is a critical component of any program – to identify areas for improvement, demonstrate program success to potential funders, and build the practice-based evidence to support the field. Newly launched programs should consider establishing baseline metrics and data collection protocols at the development stage, to assist with future evaluation efforts. Programs that are already underway can use predictive analytics and rapid cycle evaluation to improve program effectiveness. Below, we have compiled a sampling of evaluation resources that may be beneficial to program practitioners and health care leaders when implementing food insecurity programs.
When developing an evaluation plan, consider how to achieve maximum results while placing a minimum burden on program participants. Evaluations should include both short-term and long-term outcomes to measure early success, identify areas for improvement, and track progress toward long-term goals.
CDC’s Program Performance and Evaluation Office offers information and resources for public health evaluation:
Community Tool Box is a user-friendly toolbox adapted from CDC’s resources from the Work Group for Community Health and Development at the University of Kansas
The National Collaborative on Childhood Obesity Research (NCCOR) offers resources for health care-community partnerships that address obesity prevention, many of which are adaptable to the food insecurity context. Resources include a sample logic model for that programs may consider adapting as part of their evaluation efforts:
The Agency for Healthcare Research and Quality issued a paper on “Using Rapid-Cycle Research to Reach Goals, Awareness, Adaptation, Acceleration.” This report will be particularly useful for programs that want to quickly assess components of their intervention for continuous quality improvement and evaluation purposes.
Economic Burden Study
Food insecurity in older adults with chronic diseases is a critical public health concern and an expensive problem.
When people have uncertain access to food, their health and quality of life suffer. In fact, food insecurity has been associated with obesity, diabetes, heart disease, hypertension, asthma, and depression. Food insecurity in the U.S. is a concerning and expensive problem. But how much does it really cost us?
A Bread for the World Hunger Report estimated that in 2014 the health care cost of food insecurity was $160 billion.[i] Using information from a Canadian study [iii], our national food insecurity rate, and U.S. health care costs we estimated that food insecurity cost us $78 billion. This means that food insecurity costs our health care system $250 - $500 per person.
TACKLING HUNGER used these numbers in its Food Insecurity State Cost Calculator to estimate the cost of food security in each state. We applied the 2015 USDA state food insecurity rates [iii] and adjusted state costs for regional variations. Check out the costs in your state. Then do something about it!

Exploratory Evaluation
Hospitals, health care systems, and clinics across the country are working to identify and address food insecurity in patients with chronic disease.
A growing number of health care systems have begun to address social factors that affect health, including food insecurity, in their patient populations. Health care reimbursement models have also shifted toward value-based reimbursement, further pushing health care toward upstream preventative care models. As health care providers take on a new role, launching innovative programs to address social factors, and develop clinical-community partnership models, there is a critical need to assess these health care driven food insecurity programs. Identifying best practices that are scalable and replicable enables government agencies and private foundations to invest their funding streams into proven strategies that will return proven outcomes. Establishing an evidence base of best practices also allows program practitioners who are often working with the limited resources of funding and staff time to invest in strategies that are proven effective.
Toward these goals, TACKLING HUNGER has conducted the first phase of an exploratory evaluation to identify and assess promising practices in health care to address food insecurity and improve the health of patients with chronic disease. The exploratory evaluation used the Systematic Screening and Assessment (SSA)[1], a proven method used by the Centers for Disease Control (CDC) and others to expand practice-based evidence and conduct efficient, cost-effective, pre-evaluations of emerging innovations to identify promising practices and provide real time feedback to the field. The SSA method is used to identify a wide range of programs through a nomination solicitation process, allowing researchers to identify new and emerging programs, and engages an expert Consultative Group.
Evaluation Resources
In conducting the exploratory evaluation, we identified the need for evaluation support for health care initiated food insecurity programs. Many program implementers themselves expressed interest in evaluation resources, a need that was echoed in the CG recommendations. As a preliminary step, we have compiled useful evaluation resources in the Tools for Change section of this page, above.
