Study summary

The purpose of this study is to measure the metabolic and behavioral effects of a 12-week yoga program coupled to health education (HED) compared to HED alone.

Read the detailed description

The purpose of this study is to measure the metabolic and behavioral effects of a 12-week yoga program coupled to health education (HED) compared to HED alone. In a randomized clinical trial of 90 patients (45 patients per arm), investigators will measure the effects of the two interventions on IR, HTN, dysplidemia, and body composition (See Figure 1. Study Diagram). Subjects will be scheduled for outcome assessment at baseline, 12 weeks, and 24 weeks. In addition, investigators will collect data at baseline and 12 weeks on self-efficacy, stress, mindfulness, and mood. As a sub-study to the randomized controlled trial, investigators will measure the aerobic intensity of the yoga to estimate the dose of physical exercise provided by the yoga (n=10).

Subjects willing and eligible to participate in the RCT will receive written consent. Consented subjects will be randomized to either 12 weeks of yoga with HED versus HED alone. Subjects randomized to yoga will receive 30 to 45 minutes of weekly yoga instruction, followed by 30 to 45 minutes of HED. Subjects will receive written instructions for home yoga practice and lifestyle changes based on HED. Subjects randomized to HED alone will receive a weekly standardized HED curriculum which will be attention and time matched to the yoga with HED arm.
