Key result
Compared with non-Hispanic whites, treated non-Hispanic blacks and Mexican Americans with hypertension were significantly less likely to achieve blood pressure control (OR 0.59 and 0.71).
Why the study?
Does race/ethnicity impact hypertension awareness, treatment, and control in US adults?

Significant racial and ethnic disparities persist in hypertension awareness, treatment, and control in the United States, highlighting the need for targeted interventions.
Racial disparities in BP control persist among treated patients; hypothesis-generating for targeted interventions pending prospective trials.
Understanding the impact of patient factors on blood pressure (BP) management is an important step to developing interventions to improve cardiovascular health. The National Health and Nutrition Examination Survey (NHANES) 1999-2002 was used to identify predictors of hypertension awareness, treatment, and control. An estimated 63.3 million (31.0%) US adults currently have BP exceeding 140/90 mm Hg, and prevalence is higher for blacks than for other racial/ethnic subgroups. Among antihypertensive medication-treated patients, 51.3% are controlled. Treated blacks and Mexican Americans have the lowest rates of BP control. Mexican Americans are 0.62 times as likely to be aware and 0.61 times as likely to be treated as white persons with hypertension. Compared with whites, treated Mexican Americans are 0.71 times as likely and treated blacks 0.59 times as likely to achieve BP control. Hypertension treatment and BP control in the United States remain suboptimal, and significant racial/ethnic disparities persist. Effective interventions targeting Mexican Americans and blacks as well as whites are essential to improving hypertension management.

Giles et al. (2007) conducted a cross-sectional in Hypertension (n=3,546). Non-Hispanic Black race/ethnicity vs. Non-Hispanic White race/ethnicity was evaluated on Blood pressure control (<140/90 mm Hg) among treated hypertensive patients (OR 0.59, 95% CI 0.44-0.78). Compared with non-Hispanic whites, treated non-Hispanic blacks and Mexican Americans with hypertension were significantly less likely to achieve blood pressure control (OR 0.59 and 0.71).
