This study evaluates trends in glycemic control and severe hyperglycemia among U.S. adults with diabetes before and during the COVID-19 pandemic.
Retrospective cohort analysis using NHANES data from January 2017 to August 2023
Assessment of glycemic control (HbA1c < 7%) and severe hyperglycemia (HbA1c > 10%)
Logistic regression analysis based on demographics including age, race/ethnicity, and socioeconomic status.
Glycemic control remained stable at 59.7% pre-pandemic and 56.1% during (p=0.29)
Severe hyperglycemia increased from 5.6% to 8.5% (p=0.03)
Female participants had increased likelihood of glycemic control (aOR 1.40; 95% CI, 1.11-1.75), while Hispanic/Mexican American and Non-Hispanic Black adults had markedly higher odds of severe hyperglycemia.
