ObjectiveTo examine the association between food insecurity and achieving glycemic goals among Medicare beneficiaries with type 2 diabetes.MethodsThis study analyzed the nationally representative 2019 Medicare Current Beneficiary Survey of 1340 beneficiaries aged ≥65 years with type 2 diabetes. The binary dependent variable was whether beneficiaries’ blood glucose was at target (A1C ≤ 7.5% or average fasting blood glucose of ≤140 mg/dL, all/most of the time). Food insecurity, a binary variable, was adapted based on the USDA’s food security questions. A survey-weighted multivariable logistic model, adjusted for sociodemographics and comorbidities, was conducted to estimate predictive margins for comparing prevalence of having above-target blood glucose levels across groups.ResultsOf study beneficiaries, 20.9% reported not achieving glycemic targets. The predictive marginal prevalence of having higher than target blood glucose levels was significantly greater in females over males (23.8% [95% confidence interval [CI], 20.1–27.4] vs 17.6% [14.3–20.9]); those with less than high school education over those with college education (31.0% [23.6–38.3] vs 18.6% [14.8–22.3]); and those reporting food insecurity over their counterparts (33.4% [24.5–42.3] vs 19.1% [16.6–21.7]).ConclusionsSociodemographic disparities related to achieving blood glucose goals were observed. Screening for food insecurity and related interventions should be considered for at-risk beneficiaries with diabetes.
