Acupuncture-assisted lifestyle intervention improve the metabolic status and spontaneous brain activity of type 2 diabetes Mellitus patients: a randomized, clinical trial.

Abstract

Background: Aggressive weight management in patients with type 2 diabetes mellitus has demonstrated numerous metabolic advantages, however, existing therapies for weight control have not reached satisfactory results. This study aimed to evaluate the efficacy and safety of acupuncture in the weight management of type 2 diabetes mellitus (T2DM) patients by using a randomized, sham-controlled clinical trial design.

Methods: In this single-blind randomized clinical trial, 102 overweight adult T2DM patients were randomized into two groups. The control group receives diet, exercise, and sham acupuncture intervention, whereas the acupuncture group receives diet and exercise and acupuncture intervention, both for 1 month. Body weight and other anthropometric and laboratory indices were assessed at baseline and endpoint, meanwhile, the body fat content and spontaneous brain activity were measured by functional magnetic resonance imaging(fMRI)as the exploratory outcomes.

Results: No significant difference was observed between the studied parameters at the baseline. The body weight and BMI were significantly reduced both in the control and acupuncture groups after intervention, without statistical difference between the two groups. What's interesting is that compared to the control, the acupuncture group displayed a greater improvement in central fat tissue. It notes that the acupuncture group achieved significant liver fat content reduction than the sham acupuncture group. At the same time, the spontaneous brain activity in the occipital lobe and parietal lobe significantly increased in the acupuncture group.

Conclusion: One month of acupuncture treatment preferentially improved ectopic fat deposition and was accompanied by changes in brain activity compared with the control group, even before significant changes in total body weight had occurred. further studies of longer duration are necessary for validation.

Trial registration: The protocol of this clinical trial is registered at the Acupuncture-Moxibustion Clinical Trial Registry (AMCTR, http://www.acmctr.org/ , No. AMCTR-IOR-20000341).
