Kim EJ, et al. - Retrospective analysis of multi-year survey data was performed estimating national racial/ethnic prevalence of undiagnosed hypertension, diabetes, high cholesterol, and kidney disease and identifying characteristics associated with undiagnosed diseases. Participants were adults 18 years and older who took part in the National Health and Nutrition Examination Survey during 2011–2014. Asians had higher rates of undiagnosed hypertension and diabetes, and all minorities were more likely to have undiagnosed diabetes compared to Whites in a nationally representative cohort. Findings revealed that healthcare utilization was associated with undiagnosed medical conditions. They suggested that reliance on self-reported data could systemically underestimate the prevalence of chronic illnesses among minorities.
