Moxibustion combined with characteristic lifestyle intervention of Traditional Chinese Medicine in the treatment of abdominal obesity: A study protocol for a randomized controlled trial

BACKGROUND: Abdominal obesity occurs when excessive visceral and subcutaneous fat is built up around the abdomen and stomach, which negatively impacts human health. Moxibustion, arose from Traditional Chinese Medicine (TCM), has been widely applied in the treatment of abdominal obesity. Several studies have shown the positive effects of moxibustion in prevention and treatment of endocrine issues and excess body weight. In this context, our study aims to examine the safety and efficacy of the combination of moxibustion and characteristic lifestyle intervention of TCM in the treatment of abdominal obesity. METHODS/DESIGN: This study will be a multicenter, randomized, controlled trial conducted from September 2020 to January 2022 that includes 150 participants who have abdominal obesity and meet the eligibility criteria. The participants will be randomly divided into 3 groups in a 2:2:1 allocation ratio. The intervention group will receive moxibustion combined with characteristic lifestyle intervention of TCM; the other group will receive moxibustion combined with lifestyle intervention; the control group will receive lifestyle intervention only. Eight-week moxibustion sessions will be provided to participants assigned to the 2 intervention groups. The characteristic lifestyle intervention of TCM will also last 8 weeks, whereas the lifestyle intervention will last 12 weeks including 8-week treatment period, 4-week follow-up period. The primary outcome is the waist circumference measured by a tape measure. The secondary outcomes include obesity-related indicators, serum biochemical indexs, blood pressure, conversion score of physical symptoms, and measurement of the scale. Adverse events will be recorded during the treatment and follow-up period. DISCUSSION: The results are expected to provide clinical evidence for the application of the combination of moxibustion and characteristic lifestyle intervention of TCM in patients with abdominal obesity.
