Acupuncture for Impaired Glucose Tolerance in Overweight/Obese Population

This is a prospective, multicenter, parallel-group, participants- and assessors-blinded randomized trial aiming to evaluate the effectiveness and safety of acupuncture in improving glucose metabolism for overweight/obese Participants with IGT, in comparison with sham acupuncture.

The trial will be conducted at three hospitals in China. 196 eligible subjects will be randomly assigned (1:1) to the acupuncture or sham acupuncture group to receive either 30-session acupuncture/sham acupuncture treatment over 12 weeks based on lifestyle intervention and 24-week follow-up. The primary outcome is the change in the value of 2-hour blood glucose (2hPG) from baseline at the end of the 12-week treatment. Additionally, compliance, blinding, and safety will also be assessed. All statistical tests will be performed using a two-sided test, a p-value of less than 0.05 is considered significant.
