Study Overview
Brief Summary
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.
Detailed Description
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.

Arms & Interventions
Acupuncture Group
The acupuncture points are: EX-B3, BL18, BL20, BL21, GV20, GV29, LI11, CV12, CV10, ST25, CV6, CV4, ST40, SP6.
After piercing 15-35mm into the skin, the needles will be gently rotated and lifted three times to achieve a sense of sourness, distention, and heaviness (de qi). For EX-B3, BL18, BL20, and BL21, withdrawn afterward immediately. For GV20, GV29, LI11, CV12, CV10, ST25, CV6, CV4, ST40 and SP6, The needles will be maintained for 30 minutes.
Intervention: Acupuncture (Other)
Sham Acupuncture Group
sham acupoints are located at a horizontal distance of 20 mm to those points used in the acupuncture group, and no manipulation was carried out after piercing the skin for 1-2mm to avoid de-qi sensation.
For sham EX-B3, BL18, BL20, and BL21, withdraw immediately after piercing. For sham GV20, GV29, LI11, CV12, CV10, ST25, CV6, CV4, ST40 and SP6, The needles will be maintained for 30 minutes after puncture.
Intervention: Sham Acupuncture (Other)
Outcomes
Primary Outcomes
The change in the value of 2-hour blood glucose from baseline at the end of the 12-week treatment
Time Frame: week 12
The 2-hour blood glucose is the value of intravenous plasma glucose measured by oral 75g glucose tolerance test, which is usually used to diagnose impaired glucose tolerance and observe glucose metabolism.
Secondary Outcomes
- The proportion of participants with at least 5% reductions in body weight from baseline(weeks 4, 8, 12, 16, 24 and 36)
- The proportion of participants whose 2-hour blood glucose dropped to normal from baseline(weeks 12, 24 and 36)
- The change from baseline in the SNAQ scores(weeks 4, 8, 12, 16, 24 and 36)
- The change from baseline of TC, TG, LDL-C, and HDL-C(weeks 12, 24 and 36)
- The change from baseline of body mass index(weeks 4, 8, 12, 16, 24 and 36)
- The change from baseline of Fasting serum insulin(weeks 12, 24 and 36)
- The change in the value of 2-hour blood glucose from baseline(weeks 24 and 36)
- The change from baseline of fasting plasma glucose(weeks 12, 24 and 36)
- The change from baseline of Homeostasis model assessment-insulin resistance(weeks 12, 24 and 36)
- The change from baseline of Waist-to-Hip Ratio(weeks 4, 8, 12, 16, 24 and 36)
- The change from baseline of blood pressure(weeks 12, 24 and 36)
- The change from baseline in the IWQOL-Lite scale scores(weeks 4, 8, 12, 16, 24 and 36)
