Food security is defined as access by all persons at all times to enough food for an active, healthy life. Limited availability of nutritionally adequate and safe food or the inability to acquire these foods in socially acceptable ways is called food insecurity (FI).1

Prior to the Great Recession (2007 to 2009), the rate of FI was 11.1%; FI peaked at 14.9% in 2011 before declining to 12.3% (almost 16 million American households) in 2016.2 FI occurs most often in households with income near or below the federal poverty line or with a person living alone, in households containing children, or in households headed by a black or Hispanic person or single parent. In addition, the prevalence of FI is higher among those living in principal cities of metropolitan areas (14.2%) or in rural areas (15.0%), with the highest prevalence occurring in the South (13.5%), followed by the Midwest (12.2%), the West (11.5%), and the Northeast (10.8%).2

The interaction between FI and chronic disease is cyclical. FI results in constrained dietary options and compensatory strategies, as well as competing demands for limited resources (e.g., postponement of needed health care). Changes in health status and stress from FI can result in development and progression of chronic diseases, causing further competing demands that exacerbate FI.3 Obesity is associated with FI, especially in women and in persons with diabetes mellitus, hypertension, dyslipidemia, or depression.410 Adults with very low food security have a higher 10-year risk of cardiovascular events than those with traditional risk factors.11 In children and adolescents, FI increases the risks of hypertension, asthma, obesity, poor nutrition, infection, anemia, untreated dental caries, poorly developed social-emotional skills (in young children), poor academic achievement, and behavioral problems (in adolescent males).12

Physicians can improve the health of patients who experience FI by following the SEARCH (screen, educate, adjust, recognize, connect, help) mnemonic13 and by using the resources outlined in Table 1.

Screen

Screen all patients for FI, especially in practices that serve at-risk populations, and document findings in the electronic health record. Although the preferred screening tool for FI is an 18-item survey, two questions have been identified that can quickly assess for FI.14,15 An affirmative response (“often true” or “sometimes true” vs. “never true”) to either of the following statements can identify FI with 97% sensitivity and 83% specificity: (1) Within the past 12 months we worried whether our food would run out before we got money to buy more, and (2) Within the past 12 months the food we bought just didn't last, and we didn't have money to get more.15 Screening could be completed during the intake process so that physicians can focus their time on helping patients who screen positive.16

Educate

Educate patients at risk of FI about appropriate coping strategies. Although some individuals with limited resources manage without major disruptions to food intake, many eat less or eat less healthy foods to get by. Physicians can help patients avoid other unhealthy coping strategies such as prioritizing food quantity over quality; stretching or diluting food and beverages; avoiding medical care or filling prescriptions; eating one large, highly satiating meal per day; choosing a small variety of low-cost or fast foods; fasting or skipping meals; and overeating when food is available. Some individuals may go to the emergency department to obtain food or may commit a petty crime to get a jail meal.13

Educate patients with diabetes who are at increased risk of hypoglycemia to coordinate hypoglycemic medications (e.g., sulfonylureas, prandial insulin) with meals rather than time of day. Patients should avoid taking these medications if they are not going to eat a meal, no matter the reason. Educate patients with hypertension or heart disease about sodium restriction because sodium levels may be higher in prepackaged donated food or low-cost fast food.

Adjust

Adjust the patient's medication if it should be taken with food. Prescribe medications that minimize the likelihood of hypoglycemia for patients with FI who have diabetes.13 Hypoglycemia may occur more often toward the end of the month because of the lack of financial resources to buy food.17

A physician or registered dietitian nutritionist can help patients adjust meal plans and timing of meals to reduce negative interactions between the patient's diet and prescribed medications for chronic conditions.18 Prescribe medications that are effective and affordable and that promote optimal adherence.

Recognize

Recognize that FI is typically recurrent but is usually not chronic. Patients should be screened at each visit to ensure appropriate evaluation and management of intermittent or recurrent FI.

Connect

Connect patients with assistance programs and encourage patients with FI to use food banks. See eTable A for more information on available programs.

Help

Help other health care professionals recognize that poor health and FI often exacerbate one another. Addressing FI during medical education enables faculty and trainees to understand the role of FI in population health and to propose solutions.19 Physicians should advocate for food security resources in clinics, hospitals, and communities (Table 1).
