    Abstract:
    OBJECTIVES: The objectives of this study were to examine the trends in the prevalence of type 2 diabetic patients with comorbid hypertension and blood pressure (BP) control rates in the United States and determine factors associated with these outcomes. METHODS: We used data from National Health and Nutrition Examination Surveys (NHANES) III (1988-1994) and NHANES 1999-2004, a cross-sectional sample of the noninstitutionalized US populations. Type 2 diabetic patients were identified as patients at least 30 years of age with physician-diagnosed diabetes who were taking insulin or oral antidiabetic drugs to manage the condition. A diagnosis of hypertension was based on physician diagnosis, treatment with antihypertensive medications, or BP at least 140/90 mmHg. BP control was defined as diabetic patients who maintained BP <130/80 mmHg. Logistic regression was used to estimate risks of high BP, and odds of high BP treatment and control rates, after adjusting for demographic and clinical risk factors. RESULTS: The age-adjusted prevalence of diabetic patients and those with hypertension increased significantly from 5.8 to 7.1% and 3.9 to 4.7%, respectively, from NHANES III to NHANES 1999-2004. Among diabetic patients with hypertension, patients who were treated with medication or lifestyle or behavioral modification therapy have increased significantly from 76.5 to 87.8% during the observation period. The proportion of patients who controlled BP increased from 15.9 to 29.6%, but 70% of patients still did not meet the target BP goal. CONCLUSION: Aggressive public health efforts are needed to improve BP control in type 2 diabetic patients with hypertension.
