title: Association between highly active antiretroviral therapy and hypertension in a large cohort of men followed from 1984 to 2003.
abstract: OBJECTIVE
  UO1-AI-35041: To examine the impact of HIV infection and highly active antiretroviral therapy on systolic and diastolic hypertension.
  
  
  METHODS
  Cohort study with semi-annual assessment of the outcome.
  
  
  METHODS
  We studied 5578 participants of the Multicenter AIDS Cohort Study with blood pressure measurements obtained between 1984 and 2003. The primary outcomes were systolic hypertension (SH; systolic blood pressure > 140 mmHg) and diastolic hypertension (DH; diastolic blood pressure > 90 mmHg). Statistical analyses were performed using multiple logistic regression with robust variance estimation.
  
  
  RESULTS
  Of the 84 813 person-visits available for analysis, 7.3 and 8.0% showed SH and DH, respectively. Controlling for age, race, body mass index, and smoking, HIV positive men not taking antiretroviral therapy were significantly less likely than HIV negative men to have SH [odds ratio (OR), 0.79; 95% confidence interval (CI), 0.70-0.89], as were men taking mono/combination therapy (OR, 0.69; 95% CI, 0.59-0.80). The prevalence of SH among men taking highly active antiretroviral therapy (HAART) for less than 2 years was similar to that among HIV negative men (OR, 1.06; 95% CI, 0.87-1.30), but was significantly higher thereafter; for 2 to 5 years of HAART (OR, 1.51; 95% CI, 1.25-1.82) and for more than 5 years of HAART (OR, 1.70; 95% CI, 1.34-2.16). In contrast, DH was not significantly higher among men with prolonged HAART use compared to that among HIV negative controls.
  
  
  CONCLUSIONS
  Prolonged HAART use was significantly associated with a higher prevalence of SH. This finding suggests that individuals taking HAART may be at increased risk of developing hypertension-related conditions and underscores the importance of blood pressure monitoring among these individuals.
