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.

Conditions

  • Prehypertension
  • Prehypertension (Elevated Blood Pressure) or Hypertension

Interventions

BEHAVIORAL

Lifestyle Modification Advice

Participants received verbal lifestyle modification advice, including reducing salt intake, avoiding salted foods, weight loss or maintenance of normal body weight when appropriate, regular aerobic physical activity, and limiting alcohol consumption.

BEHAVIORAL

DASH Diet

Participants received an individualized Dietary Approaches to Stop Hypertension (DASH) diet plan. Total energy requirements were calculated, and dietary plans were prepared according to the recommended DASH food group servings.
