NCT06744933

Brief Summary

The goal of this clinical trial is to learn whether self-administered auricular acupressure integrated with a smartphone application works to reduce weight in patients with obesity accompanied with obesity-related comorbid illness. The main questions it aims to answer are:

  • Is there significant difference in the Body Mass Index (BMI) between the self-administered auricular acupressure integrated with a smartphone app (Version 2) group (experimental group) and the usual care group, in people with obesity accompanied with metabolic syndrome?
  • Are there significant differences in other anthropometric parameters between the two groups? These parameters include waist circumference, body fat percentage, skeletal muscle percentage, and waist-to-hip ratio.
  • Are there any significant differences in obesity-related parameters between the two groups? These parameters include blood lipid profile (triglyceride, total cholesterol, low-density lipoprotein (LDL), and high-density lipoprotein (HDL)), blood glucose concentrations (fasting glucose and glycated haemoglobin/ HbA1c), and blood pressure. Participants in the experimental group will:
  • Be affixed with 6 to 8 hypoallergic Vaccariae Semen ear patches on one ear each time
  • Visit the clinic twice a week to change a new set of ear patches on the opposite ear
  • Will undergo this intervention for 8 weeks
  • Install a smartphone application which will send pop-up notifications to remind them to press on the ear patches regularly every day
  • Keep a record on the number of times pressing on the smartphone application

Outcome Measures

Primary Outcomes (1)

  • Change from the baseline in the mean Body Mass Index (BMI) at one month and four months after the completion of the intervention

    BMI is a continuous numerical scale. Zero is equivalent to no change in weight; Positive change is equivalent to weight gain; Negative change is equivalent to weight reduction.

    Baseline, one month post-intervention, and four months post-intervention

Secondary Outcomes (7)

  • Change from baseline in mean waist circumference at one month and four months after the completion of the intervention

    Baseline, one month post-intervention, and four months post-intervention

  • Changes from baseline in mean body fat percentage and skeletal muscle percentage at one month and four months after the completion of the intervention

    Baseline, one month post-intervention, and four months post-intervention

  • Change from baseline in mean waist-to-hip ratio at one month and four months after the completion of the intervention

    Baseline, one month post-intervention, and four months post-intervention

  • Changes from the baseline in the mean blood lipid profile at one month and four months after the completion of the intervention

    Baseline, one month post-intervention, and four months post-intervention

  • Changes from the baseline in the mean blood glucose concentrations at one month and four months after the completion of the intervention

    Baseline, one month post-intervention, and four months post-intervention

  • +2 more secondary outcomes

Self-administered auricular acupressure integrated with a smartphone application

EXPERIMENTAL

Patients in this group will undergo TCM syndrome differentiation, and then be given 6 to 8 hypoallergic Vaccariae Semen ear patches on one ear. 6 of the auricular acupoints will be compulsory, while the additional 1 to 2 acupoints will be selected according to the TCM syndrome of the patient. These 6 mandatory acupoints were selected according to previous literature and expert opinion. The research staff will use an ear model to demonstrate to the patients how to press on the auricular acupoints and require them to perform a return demonstration to ensure they can perform auricular acupressure correctly by themselves. The patient will then be required to visit the clinic twice a week and will change a new set of ear patches on the same acupoints of the opposite ear. This intervention will last for 8 weeks. Their BMI (and weight) and their satiety level will be monitored once a week while they visit the clinic.

Combination Product: Self-administered auricular acupressure integrated with a smartphone application

Usual care

NO INTERVENTION

The usual care group will receive no intervention. They will only be assessed on the outcomes.

Interventions

6 to 8 Vaccariae Semen ear patches will be affixed on one ear of the patient. The patient will be required to press on the ear patches 3 times a day, and 30 minutes before a meal. Every 3 to 4 days, the patient will visit the clinic to change a new set of ear patches on the same auricular acupoints of the opposite ear alternately. The whole course of intervention will be 8 weeks. The smartphone app will send scheduled pop-up notifications to remind patients to press on the ear patches. The patient will be required to enter the number of times pressing and of defaecation every day on the smartphone application. The smartphone application will send more notifications to the patient if he/ she has a low compliance. When the participants record the number of times pressing on the auricular acupoints, positive reinforcement messages will pop-up, such as "Excellent job!" for those with good compliance while "You are almost there! Keep going!" for those with poor compliance.
