About this study

Official title: The Effect and Safety of Acupoint Thread Embedding on Over-weight and Obesity Treatment : A Randomized, Single-Blind, Sham- Controlled Study

The investigators describe a protocol for a randomized controlled trial to find out the effect and safety of acupoint thread embedding on losing weight in obese patients.

Read the detailed description

Obesity refers to a complex chronic disease in which there is excessive accumulation of body fat. As of 2016, there were more than 650 million obese people worldwide, and it is expected to reach 1.12 billion by 2030, with at least 2.8 million deaths due to obesity each year, according to surveys. In Europe, 60 percent of the population is already overweight or obese. The incidence of obesity is also increasing rapidly in China, with a recent report by The Lancet showing that the number of obese people in China has reached 85 million, making it the country with the highest number of obese people in the world. In 2002, the China Obesity Task Force recommended threshold value to define overweight as Body Mass Index (BMI) of ≥ 24 kg/m2, a waist circumference (WC) ≥of 85 cm for men and a WC ≥ 80 cm for women, or a Waist-to-Hip Ratio (WHR) of ≥ 0.9 for men and a WHR ≥ 0.8 for women, and to define obesity as a BMI ≥ 28 kg/m2. Studies have shown that Asian populations have higher health risks at the same BMI and WC levels due to the distribution of adipose tissue. Acupoint thread embedding is a widely recognized therapy to lose weight in clinical practice.But there are some doubts about the effectiveness of acupoint thread embedding versus sham acupoint thread embedding in treating obesity due to its lack of medical evidence.

This randomized placebo-controlled clinical trial is aimed to investigate the effect and safety of acupoint thread embedding (ATE) in obese patients. The investigators designed a protocol for a randomized controlled trial, in which 132 eligible patients will be randomly assigned to one of the two groups: the ATE group (receiving ATE treatment with health education) and the sham acupoint thread embedding (SATE) group (receiving SATE treatment with health education). A total of 6 sessions of interventions will be given for consecutive 12 weeks, followed by 12 weeks follow-up period. Each session of ATE or SATE treatment will last for about 30 minutes. The primary outcome is the change of the body mass index (BMI) at week 12. The secondary outcomes include the change of patient's body weight and body circumference, results from the blood tests (FBG, LDL-C, HDL-C, TG and TC), the abdominal visceral fat tissue thickness scanned by FibroScan, data collected from the body composition analyzer, and the scores of the impact of weight on quality of life (IWQOL-Lite), the well-being index (WHO-5), visual analog scale (VAS) of appetite and hamilton anxiety scale(HAMA). All adverse effects will be accessed by the treatment emergent symptom scale (TESS) from baseline to the follow-up period. The body weight and circumferences,BMI,IWQOL-Lite, WHO-5, VAS, and the HAMA, will be calculated at baseline, week 6, week 12, and week 24. blood tests,FibroScan and the body composition analyzer's data will be calculated at baseline,week 12 and week24. All patients will be provided with the same health education brochure to choose more beneficial personalized lifestyle during the 12-week intervention period.

All analyses will be performed on the intention-to-treat (ITT) population of participants who have at least one treatment. Missing data will be handled using the multiple imputation method, on the assumption that values at each time point follow a specific distribution calculated by the computer software R V.3.5. The primary outcome is the change of the body mass index (BMI) at week 12. Linear mixed effects models will be used for analyses with the use of the statistical software SPSS V.29.0. The t-test will be used to compare the measurement data between either two groups from the baseline to follow-up; the rank sum test will be used for ranked data while the Chi-squared test will be used to analyze categorical data. The significance level that will be used for statistical analysis with 2-tailed testing will be 2.5%. Data values will mainly be presented as Mean±SD. The findings from this trial will help further explore the efficacy and safety of ATE on losing weight for patients with obesity, as well as determine the differences between the ATE and SATE treatment.

Methods of operation: With the patient in the prone position and all acupoints routinely sterilized, the acupuncturist will use sterile forceps to insert a 3-0 × 2-cm poly-p-dimethyl-hydroxy-oxazolone (PDO) thread into the tip of the #6 (0.6 mm × 60 mm) disposable embedded thread needle. The tissue around the area of the acupuncture point will be lifted with the thumb and forefinger of the non-dominant hand and the needle will be inserted into the acupuncture point to a depth of 1.5 cm with the dominant hand. Each treatment will last maximum of 10 minutes and the intervention will be repeated every 2 weeks for a total of 6 sessions.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Body Mass Index (BMI)

    one of the criteria for evaluating the body weight and health status of a person. BMI = weight (kg)/height (m)2. Each subject will be provided with a free Bluetooth Internet-enabled scale to monitor their weight at regular intervals, and the researcher will be able to access the data from the backend.

    Measured: week12

Secondary outcomes (12)
  1. Change in body weight

    The change in body weight at the end of the intervention compared to the baseline.

    Measured: week0, week6, week12, week24

  2. Body Mass Index (BMI)

    one of the criteria for evaluating the body weight and health status of a person. BMI = weight (kg)/height (m)2. Each subject will be provided with a free Bluetooth Internet-enabled scale to monitor their weight at regular intervals, and the researcher will be able to access the data from the backend

    Measured: week0, week6, week24

  3. Changes in body circumference

    Waist circumference (WC), hip circumference (HC), waist-hip ratio (WHR), waist-height ratio (WHtR), and the average value of the changes in each circumference at the end of the intervention were calculated compared with the baseline. WHR=WC/HC; WHtR=WC/height .

    Measured: week0, week6, week12, week24

  4. Body composition analysis

    Evaluating changes in body fat percentage or composition by using bioelectrical impedance analysis (BIA) device (InBody770; Biospace, Seoul, Korea)., which allows for high-density body composition measurements, including muscle mass, body water content, body fat percentage, visceral fat grade, and other body components, by bioelectrical impedance analysis.

    Measured: week0, week12, week24

  5. Changes in liver fat content

    Liver fat changes are quantitatively calculated with FibroScan.

    Measured: week0, week12, week24

  6. Fasting blood glucose (FPG)

    glucose concentration in the blood in the early morning fasting, which can reflect the function of pancreatic β-cells,HOMA-IR, Insulin level.

    Measured: week0, week12, week24

  7. Blood lipid profile

    including Low-density Lipoprotein (LDL), High density lipoprotein (HDL), triglyceride (TG), cholesterol (TC), reflects the lipid metabolism within the body.

    Measured: week0, week12, week24

  8. Impact of Weight on Quality-of-Life Scale (IWQOL-Lite)

    a 31-item self-report scale consisting of a total score and individual scores on 5 dimensions, i.e., physical functioning, self-esteem, sexuality, public stress, and work, to assess the quality of life of obese patients

    Measured: week0, week6, week12, week24

  9. Well-Being Index (WHO-5)

    shot, self-administered subjective measure of well-being over the last two weeks. It consists of 5 positively worded item that is rated on 0-6 which is 0 means at no time and 5 is all the time.

    Measured: week0, week6, week12, week24

  10. Visual analog scale (VAS) of appetite

    This method relies on a line segment of 100 mm or 150mm in length, with the two ends pointing to "I have no appetite at all" and "I have a very good appetite" respectively. Subjects mark the line according to their level of appetite. The patient was determined to have a reduced appetite if the measured line segment was <50 mm or 70 mm.

    Measured: week0, week6, week12, week24

  11. Hamilton Anxiety Scale (HAMA)

    The CCMD-3 Chinese Diagnostic Criteria for Mental Disorders lists it as an important diagnostic tool for anxiety disorders, and is often used clinically as the basis for the diagnosis and degree classification of anxiety disorders. The total score can better reflect the severity of anxiety symptoms, and can be used to evaluate the severity of anxiety symptoms in patients with anxiety and depressive disorders and evaluate the effects of various drugs and psychological interventions. According to the information provided by the Chinese scale collaboration group: the total score is ≥ 29 points, which may be severe anxiety; ≥ 21 points, there must be significant anxiety; ≥ 14 points, there is definitely anxiety; More than 7 points, there may be anxiety; If the score is less than 7, there are no anxiety symptoms.

    Measured: week0, week6, week12, week24

  12. Adverse effects

    Any adverse event (described as unfavourable or unintended signs, symptoms or diseases occurring during the trial) related to the intervention will be reported by patients and practitioners and accessed by the Treatment Emergent Symptom Scale (TESS) which is used as an associated indicator to mainly evaluate the safety of acupoint thread embedding treatment in this trial.

    Measured: week6, week12, week24
