Efficacy and Safety of Thread Embedding Acupuncture Combined With Auricular Acupuncture for Overweight and Obesity: Randomized Placebo-Controlled Trial

Overweight and obesity are chronic non-communicable diseases with a rapidly increasing global prevalence. They constitute risk factors for various chronic conditions, including cardiovascular diseases, type 2 diabetes, chronic kidney disease, cancer, as well as musculoskeletal disorders and numerous other disorders, significantly impacting the quality of life.

Numerous non-pharmacological interventions have been employed in the management of these conditions. Particularly, Auricular acupuncture (AA) has been a widely used and established method for weight management, owing to its effectiveness, safety, and convenience. Recently, a novel therapy known as Thread embedding acupuncture (TEA) has also demonstrated efficacy in weight reduction. Several studies have shown a substantial increase in treatment effectiveness when combining TEA with other acupuncture therapies. However, there is currently no available data on the combination of TEA with AA.

This study is conducted to assess the efficacy and safety of combining TEA with AA compared with AA monotherapy in overweight and obesity.

Detailed Description

Eligible participants with overweight or obesity, defined according to the criteria set by The World Health Organization Regional Office for the Western Pacific Region (Body Mass Index [BMI] of 23 kg/m² or higher), will be enrolled and subsequently randomized into two groups: the intervention group (AA + TEA group) and the placebo group (AA + Sham-TEA group), with a 1:1 allocation ratio.

In both groups, the intervention duration is eight weeks, with Auricular acupuncture (AA) administered weekly, along with recommended lifestyle modifications. For the intervention group, Thread embedding acupuncture (TEA) therapy will be added every two weeks, totaling four sessions during the eight-week period. Meanwhile, Sham-TEA will be administered in the placebo group.

Data regarding body weight, BMI, waist circumference, hip circumference, appetite, and adverse effects will be recorded immediately following randomization and weekly thereafter over the eight-week duration.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: AA + TEA
Auricular acupuncture (AA) every week in eight weeks (eight sessions). Combined with Thread embedding acupuncture (TEA) every two weeks in eight weeks (four sessions).
Other: Auricular acupuncture
Auricular acupuncture is conducted weekly in eight weeks using patches, each with a square shape and a side length of 10 mm, along with sterilized needles measuring 0.25 x 1.3 mm. Five acupoints on one ear are selected, which included Shen-men (TF4), Stomach (CO4), Spleen (CO13), Endocrine (CO18), and Hunger point. The patch with the needle will remain in place for one week.
Other: Thread embedding acupuncture
Thread embedding acupuncture is performed every two weeks in eight weeks using a single Polydioxaone thread. Needles has a gauge size of 29G, a shaft length of 38mm, and a thread length of 50mm, folded in half, and are applied to ten acupoints, including Qihai (CV6), Shuifen (CV9), and Tianshu (ST25), Shuidao (ST28), Daheng (SP15), Siman (KI14) on both sides of the body. Needles with a gauge size of 30G, a shaft length of 25mm, and a thread length of 30mm, folded in half, are used for five acupoints, which included Zhongwan (CV12) and Zusanli (ST36), Pishu (BL20) on both sides of the body. After the thread being inserted into the body, the needle will be withdrawn immediately.
Sham Comparator: AA + Sham-TEA
Auricular acupuncture (AA) every week in eight weeks (eight sessions). Combined with Sham Thread embedding acupuncture (Sham-TEA) every two weeks in eight weeks (four sessions).
Other: Auricular acupuncture
Auricular acupuncture is conducted weekly in eight weeks using patches, each with a square shape and a side length of 10 mm, along with sterilized needles measuring 0.25 x 1.3 mm. Five acupoints on one ear are selected, which included Shen-men (TF4), Stomach (CO4), Spleen (CO13), Endocrine (CO18), and Hunger point. The patch with the needle will remain in place for one week.
Other: Sham Thread embedding acupuncture
Sham Thread embedding acupuncture is performed every two weeks in eight weeks. Needles without threads has a gauge size of 29G, and a shaft length of 38mm, are applied to ten acupoints, including Qihai (CV6), Shuifen (CV9), and Tianshu (ST25), Shuidao (ST28), Daheng (SP15), Siman (KI14) on both sides of the body.
