Disability Status and Secondary Prevention Among Survivors of Stroke: A Cross‐Sectional Analysis of the 2011 to 2018 National Health and Nutrition Examination Survey

Abstract

BackgroundAmong survivors of stroke, adherence to secondary prevention care is associated with decreased risk of recurrent stroke. However, not all survivors of stroke use secondary stroke prevention treatment. We examined the association between the disability status of survivors of stroke and their treatment and control of diabetes, hyperlipidemia, and hypertension.Methods and ResultsIn a cross‐sectional analysis of the 2011 to 2018 National Health and Nutrition Examination Survey, we compared diabetes, hyperlipidemia, and hypertension treatment and control rates among self‐reported survivors of stroke age ≥20 years with and without disability. Disability was defined as self‐reporting any of 5 physical or 4 functional domains assessed using a structured questionnaire. Logistic regression models adjusted for age, sex, race and ethnicity, and history of medical conditions were used to estimate associations between disability status and risk factor treatment and control. The mean age of survivors of stroke was 65.1 years, and 55.5% were female; 76% (95% CI, 72.7%–79.3%) self‐reported at least 1 disability. Age‐standardized treatment rates for diabetes, hyperlipidemia, and hypertension were 33.1% (95% CI, 26.9%–39.2%), 67.5% (95% CI, 62.6%–72.3%), and 78.4% (95% CI, 74.6%–82.2%), respectively. Age‐standardized control rates for diabetes, hyperlipidemia, and hypertension were 86.8% (95% CI, 83.8%–89.8%), 20.5% (95% CI, 15.0%–25.9%), and 47.1% (95% CI, 42.6%–51.7%), respectively. In adjusted models, those with and without disabilities had similar odds of risk factor treatment and control.ConclusionsIn the United States, three‐quarters of survivors of stroke self‐reported a disability, and these patients had similar odds of diabetes, hyperlipidemia, and hypertension treatment and control compared with those without disability.
