Effects of the DASH Diet and Lifestyle Modification on Blood Pressure in Adults With Prehypertension
Sponsor: Antalya Bilim University
Summary
This pilot randomized controlled trial evaluated the effects of the Dietary Approaches to Stop Hypertension (DASH) diet and lifestyle modification on blood pressure in adults with prehypertension. The study was conducted among adults aged 20-64 years who were diagnosed with prehypertension based on one-week blood pressure monitoring. A total of 32 participants were randomly assigned to one of three groups: verbal lifestyle modification advice, DASH diet, or DASH diet combined with lifestyle modification. Participants were followed for 2 months. Blood pressure measurements were repeated at the end of the first and second months. Dietary intake, anthropometric measurements, body composition, physical activity records, and routine biochemical parameters were also assessed during the study.
