Abstract
Purpose
The purpose of this study was to determine the use of clinical-guideline–recommended antihypertensive regimens among Mexican Americans (MAs) and non-Hispanic blacks and whites with type 2 diabetes and hypertension.
Methods
A secondary data analysis based on National Health and Nutrition Examination Survey 2003-2012 cohort data included 1857 noninstitutionalized civilian MA, black, and white adults with type 2 diabetes and hypertension. Unadjusted and adjusted 2-way analysis of variance models evaluated whether there was a difference in the use of recommended antihypertensive regimens across race/ethnic group.
Results
There was no difference in the use of recommended regimens across race/ethnic group (MAs, 79.1%; blacks, 81.7%; whites, 82.3%). Similarly, there was no difference between blood pressure goal levels and the use of recommended therapies across race/ethnicity (P = .632). Mexican Americans were least likely and blacks most likely to be on 3 or more antihypertensive drug classes (16.8% vs 28%). Furthermore, MAs were least likely to be on recommended add-on therapies such as calcium channel blockers and diuretics.
Conclusion
Racial/ethnic medication use disparities were observed when looking at the number of antihypertensive drug classes per patient regimen, and add-on therapy use was evaluated. Along with lifestyle modifications, frequent antihypertensive regimen reassessment is necessary.
