Premier: a clinical trial of comprehensive lifestyle modification for blood pressure control: rationale, design and baseline characteristics.
(Clinical Trial;Journal Article;Multicenter Study)
PURPOSE: To describe PREMIER, a randomized trial to determine the effects of multi-component lifestyle interventions on blood pressure (BP). METHODS: Participants with above optimal BP through stage 1 hypertension were randomized to: 1) a behavioral lifestyle (BLS) intervention that implements established recommendations, 2) a BLS intervention that implements established recommendations plus the DASH diet, or 3) an advice only standard of care group. The two BLS interventions consist of group and individual counseling sessions for 18 months. The primary outcome is systolic BP at 6 months. Additional outcomes include diastolic BP and homocysteine at 6 months; systolic and diastolic BP at 18 months; fasting lipids, glucose and insulin at 6 and 18 months; and effects in subgroup. CONCLUSION: Results from the PREMIER trial will provide scientific rationale for implementing multi-component behavioral lifestyle intervention programs to control BP and prevent CVD.
