Yoga for Type 2 Diabetes

The purpose of the current proposal is to test a yoga intervention for adults with T2DM and
to gather data on the feasibility and acceptability of yoga compared to a contact control for
glycemic control. The investigators will conduct a pilot randomized controlled study with
participants randomly assigned to 1) Yoga intervention, or 2) A standard exercise (SE) group
program (comparison-control). Focus groups will be conducted with participants at the end of
the intervention to identify facilitators and barriers to yoga practice and to examine their
perceptions and beliefs about yoga and its relationship to stress and diabetes management.
The investigators will explore the effect of yoga on stress (biomarker = salivary cortisol)
that may act as a mechanism of action underlying the efficacy of yoga for improved glycemic
control. The investigators will also measure HbA1c levels, fasting and postprandial plasma
glucose at baseline, end of treatment (12-weeks), 6- and 9-month follow-ups. Study
feasibility and acceptability will be assessed using participant recruitment, attendance and
retention rates, and compliance with study protocols and satisfaction with the program.
Participants will also attend a focus-group discussion of the program at the end of
treatment. Results from this study will provide scientific basis for a future larger clinical
trial. Yoga, if found to offer advantages for glycemic control, can have potential for high
impact on current practices of diabetes management.
