Many Indians are at high risk for type 2 diabetes mellitus. The blood glucose level can be improved through a healthy lifestyle (such as physical activity and a healthy diet). Yoga can help in type 2 diabetes mellitus prevention, being a culturally appropriate approach to improving lifestyle.

A multicenter, two-arm, parallel-group, feasibility randomized controlled trial was conducted in India. The outcome assessors and data analysts were blinded. Adults at high risk for type 2 diabetes mellitus were eligible. In the intervention group, participants received a Yoga program to prevent type 2 diabetes mellitus. In the control group, participants received enhanced standard care.

The participant recruitment and follow-up and adherence to the intervention were promising in this feasibility study. In the control group, the potential contamination was low. Therefore, it should be feasible to undertake a definitive randomized controlled trial in the future that will evaluate the effectiveness of the intervention among high-risk individuals in India.
