RESUMO
INTRODUCTION: Hypertension is a growing pandemic affecting over 1 billion people worldwide; about 46% of people with hypertension are unaware. METHOD: Data from the National Health and Nutrition Examination Survey (NHANES) 2011-2018 were analyzed to assess the relationship between access to a routine place of care and undiagnosed hypertension in adults aged 18 to 64 years old. We defined undiagnosed hypertension as those meeting the 2017 American Heart Association's guidelines for stage 1 or 2 hypertension who reported not being told by their healthcare provider that they had hypertension. We used a multivariable Poisson regression model to assess the relationship between access to a routine place of care and undiagnosed hypertension. RESULT: The final analytic sample was 5345 hypertensive American adults, with 56% unaware of their status. The results indicate that lack of awareness of hypertension status was highest among those without a routine place of care [PR = 1.20, CI = (1.12-1.29), p < 0.001] compared to those with access to a routine place of care, after adjustment for sociodemographic and clinical characteristics. CONCLUSION: Access to a routine place of care in a non-emergency department setting is essential to reduce the rate of undiagnosed hypertension among American adults. Policymakers should implement policies to address the shortage of primary care providers and increase access to a routine place of care.
