Abstract

Background

Data on hypertension among Asian Americans is lacking and often aggregated, which can mask important ethnic differences. This study aims to provide a comprehensive view of hypertension and hypertension-related behaviors, including hypertension treatment, management, and information seeking, among Chinese, Korean, and Vietnamese Americans.

Methods

Data were collected from 600 foreign-born Asian Americans (201 Chinese, 198 Korean, and 201 Vietnamese participants) in the Washington–Baltimore metropolitan area, aged 18 years and over, from 2013 to 2014. Hypertension was assessed using direct measurement and self-report of having ever been told by a physician. Hypertension prevalence was compared based on the method of assessment, ethnicity, and sex.

Results

The age-adjusted hypertension prevalence from direct measurement was 27.5%, which is higher than the 2011–2014 National Health and Nutrition Examination Survey estimate for Asians (24.9%). Hypertension prevalences from self-report among Chinese, Korean, and Vietnamese were 13.4%, 23.2%, and 22.9%, respectively, which are lower than 2014 California Health Interview Survey estimates (15.6%, 18.4%, and 25.8%) with the exception of Korean participants. In regard to hypertension-related behaviors, 67.8% of hypertensive adults received management, 64.3% took antihypertensive medication, and 67.0% sought information to improve their hypertension.

Conclusions

Disaggregated data on hypertension based on measured blood pressure may prevent underestimation from self-report, particularly among those with limited healthcare access. More accurate and objective assessment of hypertension is needed for improved monitoring of hypertension among Asian-American subgroups.
