Nearly half of adults who regularly run out of food before the end of the month report being in fair or poor health. That number, 47.7%, is not a rounding error or a subgroup artifact. It's nearly double the rate for current smokers.

That comparison is the core finding from 2024 BRFSS data, and it reframes a long-standing assumption in clinical risk assessment: that tobacco use is the dominant behavioral predictor of poor self-reported health. Food insecurity, at least by this measure, isn't close to tobacco. It's ahead of it.

The Health Gap Between Food Insecurity and Smoking Is Wider Than Expected

Current smokers reported fair or poor health at rates of 27.9% and 34.4%, compared to 15.9% for never-smokers. That's a meaningful gap, and it's consistent with decades of research on tobacco's health burden.

But adults whose food usually or always ran out reported fair or poor health at 43.4% and 47.7%, against just 15% for food-secure adults. The spread between food-insecure and food-secure adults is larger than the spread between smokers and never-smokers. For every clinical quality metric that flags tobacco use but not food access, that gap represents undetected risk.

The diabetes numbers reinforce the pattern. Food-insecure adults reported diabetes rates of 17.5% and 21.8%, compared to 12.5% for food-secure adults. Current smokers came in at 12.2% and 15.2%. Chronic disease burden tracks food insecurity more closely than smoking status across both measures.

Employed and Still Running Out: The Mental Health Cost

One of the sharper findings in the data involves employed adults, a group often assumed to have baseline food security. Employed adults who always ran out of food averaged 6.1 poor physical health days per month and 11.5 poor mental health days, compared to 2.4 and 3.8 respectively for employed adults who never ran out. That's a 2.5x gap in physical health days and a 3x gap in mental health days, within the same employment category.

Long-term unemployed adults (out of work for a year or more) who always ran out of food averaged 8.6 poor physical health days and 12.5 poor mental health days. For context, long-term unemployed adults who never ran out of food averaged 5.0 poor physical health days and 6.1 poor mental health days. The food insecurity gradient holds even after controlling for employment status, and it's steep at every level.

This matters because employment is frequently used as a proxy for stability in population health models. These numbers suggest that proxy is unreliable when food access is excluded from the picture.

Hardship Stacks Up Across Income Levels, Including High Earners

Adults experiencing multiple simultaneous hardships (food insecurity, inability to pay bills, and transportation barriers) reported high rates of skipping care due to cost across nearly every income group. In the $15-25K group, 53.2% skipped care due to cost, and 63.8% faced either a cost or access barrier. In the $50-100K group, that figure was 63%.

The $200K+ group is a statistical outlier with a sample of only 9 adults, making those figures (83% skipping care due to cost, 93.3% facing either access barrier) unreliable for inference. The small-sample caveat is real. But the broader pattern across the lower income bands is consistent: once multiple hardships stack, access barriers follow regardless of income tier.

The $15-25K group had the highest rate of skipping care due to cost at 53.2%, while the under-$15K group, often assumed to be the most vulnerable, came in lower at 46.8%. That inversion suggests that the lowest-income adults may have greater access to Medicaid or safety-net programs, while those just above the eligibility threshold face the sharpest cost barriers with fewer supports.

Every quality measure that treats food insecurity as a social services problem rather than a clinical one is working with an incomplete model of patient risk. The 2024 data puts the fair or poor health rate for food-insecure adults at nearly three times the rate for food-secure adults, and well above the rate for current smokers. Tobacco cessation has been a clinical priority for decades. The case for treating food insecurity screening the same way is now in the numbers.
