In response to the COVID-19 pandemic, the federal government enacted a series of policies to expand the social safety net, including historic increases in nutritional benefits. Most nutritional spending went toward the federally funded and state-administered Supplemental Nutrition Assistance Program (SNAP), resulting in a near doubling of the average SNAP benefit between 2019 and 2021 (1). However, many of these increases were temporary, with 16 states deimplementing SNAP emergency allotments by 2022 (2). Despite these major policy shifts, little is known about how food insecurity changed among low-income adults over the course of the pandemic, including those with diet-sensitive chronic conditions.Objective: To examine food insecurity among low-income adults during versus before the pandemic.Methods: We used data from the National Health Interview Survey (NHIS), a nationally representative survey from the National Center for Health Statistics. We included 2019 as a prepandemic reference and both 2021 and 2022 cycles but excluded 2020 because the onset of the pandemic created challenges in administering the in-person survey. We included adults aged 18 years or older and defined low-income adults as those with household incomes at or below 200% of the federal poverty limit (3). Our main outcome was food insecurity within the past 30 days, defined as 3 or more affirmative responses on the U.S. Adult Food Security Survey Module (4) (Supplement).Survey-weighted logistic regression models were fit to compare food insecurity among low-income adults in 2021 and 2022 compared with 2019, with adjustment for age and sex. Our models included an interaction term for SNAP benefits and year. We repeated the analysis for subgroups based on receipt of SNAP benefits and presence of diet-sensitive chronic conditions (self-reported diabetes, hypertension, hyperlipidemia, or body mass index >30 kg/m2).Nationally representative estimates and SEs accounted for the NHIS survey design. Analyses were performed using SAS Enterprise Guide, version 7.15 (SAS Institute).Findings: The unweighted sample included 25 127 low-income U.S. adults, of whom 16 518 had diet-sensitive chronic conditions. Weighted baseline characteristics are shown in Table 1 and demonstrate increases in SNAP enrollment and unemployment during the pandemic.Table 1.

Baseline Characteristics of Low-Income U.S. Adults in the National Health Interview Survey Before (2019) and During (2021 and 2022) the Pandemic*Food insecurity among low-income adults decreased from 20.6% (95% CI, 19.4% to 21.7%) in 2019 to 15.5% (CI, 14.3% to 16.7%) in 2021 (adjusted risk difference [aRD], −5.1 percentage points [CI, −6.7 to −3.5 percentage points]) and returned to prepandemic levels in 2022 (20.1% [CI, 18.9% to 21.3%]; aRD, −0.4 percentage points [CI, −2.1 to 1.3 percentage points]). Among the subset receiving SNAP benefits, food insecurity decreased from 34.6% (CI, 32.1% to 37.0%) in 2019 to 21.6% (CI, 19.3% to 23.9%) in 2021 (aRD, −12.8 percentage points [CI, −16.0 to −9.6 percentage points]) and remained lower in 2022 (27.0% [CI, 24.8% to 29.3%]; aRD, −7.3 percentage points [CI, −10.6 to −4.0 percentage points]). Changes in food insecurity among low-income adults without SNAP benefits were more modest, decreasing from 15.4% (CI, 14.3% to 16.5%) in 2019 to 12.9% (CI, 11.6% to 14.1%) in 2021 (aRD, −2.6 percentage points [CI, −4.3 to −0.9 percentage points]) and 16.9% (CI, 15.5% to 18.2%) in 2022 (aRD, 1.5 percentage points [CI, −0.3 to 3.2 percentage points]).Food insecurity was higher among low-income adults with any diet-sensitive chronic condition. Food insecurity decreased from 23.3% (CI, 21.8% to 24.8%) in 2019 to 17.1% (CI, 15.5% to 18.6%) in 2021 (aRD, −6.4 percentage points [CI, −8.5 to −4.3 percentage points]) but then returned to prepandemic levels in 2022 (21.9% [CI, 20.4% to 23.4%]; aRD, −1.2 percentage points [CI, −3.4 to 1.0 percentage points]). Greater differences were seen in 2022 in adults with more chronic conditions (Table 2).Table 2.

The rate of missing responses to the Food Security Survey Module was low ( 30 kg/m2 based on self-reported height and weight. Download table Table 2. Food Insecurity Among Low-Income U.S. Adults During (2021 and 2022) Compared With Before (2019) the Pandemic*Discussion: Food insecurity decreased in 2021 compared with prepandemic levels among low-income adults, despite worsening unemployment and economic loss. Although food insecurity returned to prepandemic levels in 2022, rates remained lower for those enrolled in SNAP and those with multiple diet-sensitive chronic conditions.Our finding that food insecurity improved most among SNAP beneficiaries (who had greater prepandemic food insecurity) highlights the importance of financial relief and nutritional benefits, particularly in this more vulnerable group. Unfortunately, many states elected to end SNAP emergency allotments early, which may explain some of the increase in food insecurity in 2022 (2). Our findings extend prior studies by examining food insecurity through the end of 2022 and evaluating a higher-risk subpopulation (5). Limitations include that outcomes were based on self-reports and were not assessed in the same participants from year to year.Food insecurity among low-income adults reached levels well below prepandemic levels in 2021 but returned to prepandemic levels in 2022. Our findings highlight the implications of pandemic-era SNAP and financial benefits on food insecurity and provide important insights as Congress debates the upcoming farm bill, which will determine the next 5 years of nutritional policy in the United States.References1.
