Abstract

Objectives: To determine the relationship between food insecurity and periodontitis among adults in the United States (US). Methods:
Secondary analysis of the 2009-2014 National Health and Nutrition Examination Survey data. The sample included 6,108 US participants
aged ≥ 30 years in a probability weighted sample. Periodontitis status was measured in full-month oral examinations at 6 sites per tooth
for clinical attachment loss and periodontal probing depth. Food insecurity was assessed by the 18-item US Food Security Survey Module.
Results: Controlling for covariates, multiple logistic regression showed that periodontitis was associated with low food security (adjusted
odds ratio (aOR)=1.30, 95% CI: 1.08–1.57). Risk factors for periodontitis included HbA1c ≥ 7% (aOR=1.74, 95% CI: 1.26–2.40), seeking
emergency dental care (aOR=1.36, 95% CI:1.19–1.55), smoking status, racial minorities, low income, and older age. Protective factors for
periodontitis were annual dental visit (aOR=0.52, 95% CI: 0.43–0.64), health insurance (aOR=0.66, 95% CI: 0.54–0.80), female gender,
and college education. Conclusions: Food insecurity was associated with a higher risk of periodontitis among US adults. Having enough
food to eat is a basic human right and would improve well-being.
