Effect and safety of electroacupuncture on weight loss in obese patients with pre-diabetes: study protocol of a randomised controlled trial

Introduction Obesity has been identified as a significant risk factor for several chronic conditions, including diabetes, tumours and cardiovascular disease, and has been associated with increased mortality rates. Despite the well-established clinical practice of electroacupuncture (EA) as a potential treatment option for obesity, its efficacy remains questionable, primarily due to the paucity of empirical evidence supporting its therapeutic benefits. Methods and analysis The present study aims to investigate the efficacy and safety of EA for weight loss in obese individuals with pre-diabetes, using a randomised, placebo-controlled clinical trial design. A total of 256 eligible patients will be randomly assigned to one of two groups: EA (comprising EA treatment with health education) or superficial acupuncture (SA) (comprising SA treatment with health education). The intervention will be administered three times per week for the initial 12 weeks, two times per week for the subsequent 8 weeks and one time per week for the final 4 weeks, with a 24-week follow-up period. The primary outcome measure will be the percentage of patients who achieve a reduction of 10% or more in their body weight at week 24. Secondary outcome measures will include changes in body weight and body mass index, blood test results, data collected by the body composition analyser, size of adipose tissue scanned by MRI of the abdomen and the Impact of Weight on Quality of Life, the 21-item Three-Factor Eating Questionnaire-Revised and the Food Craving Questionnaire-Trait. The Treatment Emergent Symptom Scale will be employed to monitor every adverse reaction from baseline to follow-up. Ethics and dissemination This trial has received ethical clearance from the Ethics Committee of Shanghai Municipal Hospital of Traditional Chinese Medicine under the registration number 2021SHL-KY-74. All participants will provide their written informed consent prior to their enrolment. The findings of this investigation will be disseminated through peer-reviewed publications and scholarly conferences. Trial registration number NCT05237089 .
