BACKGROUND: The burden of hypertension and related health care needs among Mexican Americans will likely increase substantially in the near future.
OBJECTIVES: In a nationally representative sample of U.S. Mexican American adults we examined: 1) the full range of blood pressure categories, from normal to severe; 2) predictors of hypertension awareness, treatment and control and; 3) prevalence of comorbidities among those with hypertension.
DESIGN: Cross-sectional analysis of pooled data from the National Health and Nutrition Examination Surveys (NHANES), 1999-2004. PARTICIPANTS: The group of participants encompassed 1,359 Mexican American women and 1,421 Mexican American men, aged 25-84 years, who underwent a standardized physical examination.
MEASUREMENTS: Physiologic measures of blood pressure, body mass index, and diabetes. Questionnaire assessment of blood pressure awareness and treatment.
RESULTS: Prevalence of Stage 1 hypertension was low and similar between women and men ( approximately 10%). Among hypertensives, awareness and treatment were suboptimal, particularly among younger adults (65% unaware, 71% untreated) and those without health insurance (51% unaware, 62% untreated). Among treated hypertensives, control was suboptimal for 56%; of these, 23% had stage >/=2 hypertension. Clustering of CVD risk factors was common; among hypertensive adults, 51% of women and 55% of men were also overweight or obese; 24% of women and 23% of men had all three chronic conditions-hypertension, overweight/obesity and diabetes.
CONCLUSION: Management of hypertension in Mexican American adults fails at multiple critical points along an optimal treatment pathway. Tailored strategies to improve hypertension awareness, treatment and control rates must be a public health priority.
