Summary
To compare the effectiveness of advice versus two multicomponent lifestyle interventions to control blood pressure in participants with Stage 1 hypertension or higher than optimal blood pressure. BACKGROUND: A large body of data has been collected over the years documenting that on the one hand, reduced sodium intake, increased physical activity, weight loss, and moderate alcohol ingestion (Comprehensive Intervention) have been associated with a modest reduction of both systolic and diastolic blood pressure in with high normal and Stage 1 hypertension. On the other hand, the Dietary Approaches to Stop Hypertension (DASH) study has shown that a diet rich in fruits, vegetables, low-fat dairy products, and decreased saturated fat, total fat, and cholesterol (DASH intervention) reduced both diastolic and systolic blood pressure in similar baseline blood pressure groups. DESIGN NARRATIVE: A multicenter study to determine the BP-lowering effects of two multi-component lifestyle intervention programs compared with advice only. Eight hundred and ten men and women were randomly assigned to one of three treatment arms: (A) advice only; (B) comprehensive lifestyle intervention, in which participants received an intensive behavioral intervention program to facilitate achieving current lifestyle recommendations for BP control (reduced salt intake, increased physical activity, reduced alcohol intake, and weight control or weight loss if needed); and (C) comprehensive lifestyle intervention plus the DASH diet, in which participants received a behavioral intervention program to promote the DASH dietary pattern in addition to the same lifestyle recommendations for BP control. Participants were followed for 18 months. The primary outcome variable was systolic blood pressure measured at six and 18 months after randomization. Other variables included diastolic blood pressure, dietary adherence, physical activity, and onset of hypertension over the 18 months of follow-up. The study completion date listed in this record was obtained from the "End Date" entered in the Protocol Registration and Results System (PRS) record.
Protocol
This section provides details of the study plan, including how the study is designed and what the study is measuring.In this clinical study, participants are placed into groups randomly, like flipping a coin. This ensures that the study is fair and unbiased, making the results more reliable. By assigning participants by chance, researchers can better compare treatments without external influences.
Other Ways to Assign Participants
Non-randomized allocation: Participants are assigned based on specific factors, such as their medical condition or a doctor's decision.
None (Single-arm trial): If the study has only one group, all participants receive the same treatment, and no allocation is needed.
Eligibility
Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.Conditions
