title: Trends in blood pressure control and treatment among type 2 diabetes with comorbid hypertension in the United States: 1988-2004.
abstract: OBJECTIVE
  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.
  
  
  CONCLUSIONS
  Aggressive public health efforts are needed to improve BP control in type 2 diabetic patients with hypertension.
