Abstract P022: Uncontrolled Hypertension and Lifestyle Factors among US Adults with Disabilities
Introduction: While hypertension is a key treatable risk factor for cardiovascular disease, it is not controlled in an estimated 36 million US adults. Previous research has shown that nearly half of adults with disabilities have hypertension and that adults with disabilities are more likely to have hypertension than those without disabilities. However, no study has documented the prevalence of uncontrolled hypertension among the disability population. Our objectives were 1) to determine the prevalence of uncontrolled hypertension among adults with a disability, and 2) estimate the prevalence of awareness, treatment with blood pressure (BP)-lowering medication, and lifestyle factors among adults with disabilities who have uncontrolled hypertension.
Methods: Using nationally-representative data from the 2001-2010 National Health and Nutrition Examination Survey for 10,805 participants aged ≥20 years with a disability (self-reported limitation in cognition, hearing, vision, or mobility), we examined the prevalence of hypertension (measured systolic BP ≥140, diastolic BP ≥90 or self-reported use of BP-lowering medication) and uncontrolled hypertension (systolic BP ≥140 or diastolic BP ≥90).
Among those with uncontrolled hypertension, we estimated the prevalence of awareness (ever told by a doctor that had hypertension), treatment (self-reported use of BP-lowering medication), and lifestyle factors (measured body mass index and dietary sodium intake and self-reported aerobic physical activity and cigarette smoking).
Results: Nearly 38% of US adults have a disability. Overall 46.0% (nearly 37 million) of US adults with disabilities have hypertension. Of those, nearly 20 million (52.4%) had uncontrolled hypertension. Over half of those with uncontrolled hypertension were aware and treated (52.9%), 13.6% were aware but untreated, and 33.4% were unaware. Among those with uncontrolled hypertension 40.5% were obese, 52.1% were physically inactive (had no bouts of aerobic physical activity per week that lasted ≥10 minutes), 18.2% were current smokers, and 62.0% had an average sodium intake of ≥2,300 mg per day.
Conclusion: Over half of the 37 million adults with disabilities who have hypertension do not have it controlled; and of those, one third are unaware they have hypertension. This study highlights the need to regularly measure and monitor blood pressure among adults with disabilities. It also identifies adults with disabilities as an important population to include in public health efforts that support and encourage healthy behaviors that might improve BP control and lower risk for cardiovascular disease.
