Effect of Community-Based Structured Yoga Program on Hba1c Level among Type 2 Diabetes Mellitus Patients: An Interventional Study.

Context: In view of the rising burden of type 2 diabetes mellitus (DM) cases in India, there is an urgent need for an effective, low-cost, sustainable intervention controlling diabetes thus preventing complications.

Aims: This study aimed to assess the effect of structured yoga programs on diabetes.

Subjects and methods: This was a community-based interventional study that was conducted in an urban resettlement colony of Delhi, India. Known diabetes patients with glycated hemoglobin (Hb1Ac) ≥6.5% were enrolled from 12 randomly selected blocks of the community with a sample size of 192 in each intervention and wait-listed control arm. The intervention was structured yoga of 50 min daily, 2 consecutive weeks in a nearby park and health center followed by twice a week home practice up to the 3^rd month. The primary outcome measure was HbA1c% and secondary outcome measures were lipid profile and fasting blood glucose.

Statistical analysis used: Aper-protocol analysis was done. Mean, standard deviation (SD), and 95% confidence interval were estimated. The level of significance was considered for 0.05.

Results: There was a significant decrease of Hb1Ac (0.5%, SD = 1.5, P = 0.02), total cholesterol (11.7 mg/dl, SD = 40.5, P < 0.01), and low-density lipoprotein (3.2 mg/dl, SD = 37.4, P < 0.01) from baseline to end line in the intervention group. These changes in intervention group were also significantly different from the change in the wait-listed control group. The other variables did not change significantly.

Conclusions: It revealed that structured yoga program improved glycemic outcome and lipid profile of individuals in a community-based setting. Yoga can be a feasible strategy to control hyperglycemia, lipid levels, and can help better control type 2 DM.
