Disparities in Reporting a History of Cardiovascular Disease Among Adults With Limited English Proficiency and Angina

IMPORTANCE: Individuals with limited English proficiency (LEP) may be unaware of underlying cardiovascular disease (CVD) owing to a lack of diagnostic testing or poor communication with health care practitioners. OBJECTIVE: To evaluate whether participants with anginal symptoms and LEP would be less likely to report a history of CVD compared with those without LEP. DESIGN, STUDY, AND PARTICIPANTS: This population-based cross-sectional study combined data from 5 National Health and Nutrition Examination Survey (NHANES) cycles conducted from 2007 to 2016. Each cycle includes an interview that collects demographic, dietary, and health-related data as well as a medical examination component in which physiological measurements are taken. All NHANES participants aged 40 years or older who took the Rose questionnaire were included. Data were analyzed from September 2020 to April 2021. EXPOSURES: LEP was defined as a participant receiving the survey in a non-English language or by interpreter. MAIN OUTCOMES AND MEASURES: The 7-item Rose questionnaire assessed the presence of anginal symptoms. Self-reported CVD was defined as history of heart failure, coronary heart disease, angina pectoris, or myocardial infarction. The association between LEP status and self-reported CVD among those with anginal symptoms was determined in multivariable-adjusted models. All analyses were weighted per NHANES analytic protocols. RESULTS: Among 19 320 participants (mean [SD] age, 57.8 [11.8] years; 9344 [47.2%] male; 4145 [10.6%] Black; 2743 [6.3%] Mexican American; 2111 [4.6%] other Hispanic; 8386 [71.6%] White; and 1935 [6.9%] other race), 583 (3.0%) reported anginal symptoms. Of these, most were non-LEP (484 [96.1%]), women (344 [62.1%]), White (251 [66.8%]), and did not report having CVD (347 [62.8%]). Among those with angina, 73 of 99 respondents with LEP (79.0%) reported not having a history of CVD, compared with 274 of 484 without LEP (61.4%; P = .002). Participants with LEP had 2.8-fold higher odds of not reporting a history of CVD compared with participants without LEP (odds ratio, 2.77; 95% CI, 1.38-5.55; P = .005). CONCLUSIONS AND RELEVANCE: Among NHANES participants reporting anginal symptoms, participants with LEP were more likely not to report having CVD. This discrepancy may be because of higher rates of undiagnosed CVD or lower awareness of such diagnoses among individuals with LEP. Our findings highlight the relevance of communication strategies for individuals with LEP to provide effective intervention and treatment for CVD prevention.
