Abstract TP150: Prevalence of Uncontrolled Vascular Risk Factors Among Stroke and Non-Stroke Adults in the United States: Analysis of National Health and Nutrition Examination Survey (NHANES) 2011–2023

Background: Effective management of vascular risk factors such as hypertension, diabetes, obesity, smoking, and hyperlipidemia is critical for secondary prevention after stroke. However, there is limited national-level evidence on long-term trends in these risk factors, particularly when compared stroke survivors to non-stroke individuals. Previous study showed persistent trend of poorly controlled vascular risk factors among stroke population throughout the years of 2009 – 2020. Here, we present comparison between stroke and non-stroke population during the 2011-2023 period. Methods: We analyzed nationally representative data from NHANES cycles 2011–2023 (N ≈ 34,000 adults). Stroke status was self-reported. Uncontrolled hypertension was defined as systolic blood pressure ≥140 mmHg or diastolic ≥90 mmHg; high cholesterol as LDL >70 mg/dL, or if unavailable, total cholesterol >200 mg/dL; uncontrolled diabetes as HbA1c >7%; obesity as BMI ≥30 kg/m2; and smoking by self-report. Weighted prevalences with 95% confidence intervals were estimated by stroke status, age (18–50, >50 years), sex, and race/ethnicity (Mexican American, Other Hispanic, Non-Hispanic White, Non-Hispanic Black, Other/Multiracial). Results: Across cycles, stroke survivors consistently had higher prevalences of uncontrolled hypertension (30–50% vs. 15–20% without stroke), diabetes (15–20% vs.
