Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All randomised participants will have one treatment session per week for a period of 12 weeks and a 8 week follow up period.
Electroacupuncture (EA)
The intervention consists of 12 weekly sessions, each session includes EA treatment with 30 mins needles retention EA point selection includes Zusanli (ST36), Sanyinjiao (SP6), Tianshu (ST25), Zhongwan (CV12), Fenglong (ST40), Guanyuan (CV4), Qihai (CV6), Yinlingquan (SP9). The location of the acupuncture points will follow the standard point location in western Pacific region published by WHO (World Health Organization, 2008).
Stainless steel single-use disposable needles (Seirin, Seirin Coporation, Japan) will be used and the needles are sterilised, individually packed with a length of 40 mm. Skin sterilisation will be performed by applying 70% isopropyl alcohol swab to the area. All acupuncture points will be needled perpendicularly with guide tube. Insertion depth will be approximately 25 mm, depending on the location of individual points. Each point will be connected to an electro-stimulator continuous wave at a frequency of 30 Hz. All needles will be removed after 30 minutes of electro-stimulation.
A registered acupuncturist will be responsible for administering the EA treatments; they will also be responsible for recording each treatment into the participant’s treatment logbook. The details of the logbook include date, time, the duration of the treatment, practice of mindfulness meditation, adverse event and signed by the acupuncturist.
Mindfulness Meditation
The mindfulness meditation (MM) intervention involved practising a 10-minutes pre-recorded mindfulness meditation after each acupuncture treatment. They will also be instructed to self-practise mindfulness meditation daily at their own time, and be given a logbook to record the frequency and duration of their self-practised mindfulness meditation.
This MM is adapted from the MB-EAT program which developed by Jean Kristeller (Kristeller & Hallett, 1999). It is a sitting meditation to be practised in individual settings, which requires participants to focus on their awareness through breathing, and the audio will be recorded by a registered psychologist. A copy of the mindfulness meditation information and instruction booklet will be given to the participants in the first treatment session. The booklet will explain what mindfulness meditation is, and provides clear instruction for practising mindfulness meditation.

Comparator / control treatment
Sham Electroacupuncture (SEA)
The SEA also consist of 12 weekly sessions, this is penetrating sham acupuncture on non-acupuncture points (1 cm away from acupuncture point and meridian). The same type of acupuncture needles will be used for SEA with the exact skin sterilisation method. All acupuncture points will be needled perpendicularly with guide tube. Insertion depth will be approximately 25mm, depending on the location of individual points. Each point will be connected to a sham electro-stimulator (showing a continuous wave at frequency of 30 Hz but without actual stimulation). All needles will be removed after 30 minutes of electro-stimulation.

Outcomes
Primary outcome [1] 305921 0
Change in BMI, BMI is calculated by Body weight (in Kg) divided by the square of body height in metre. The measurements will be taken at RMIT University Chinese Medicine Research Laboratory, Body height will be measured using a body height measuring tape while a balance scale will be used for measuring the body weight.

Primary outcome [3] 305958 0
Change in waist and hip ratio. Where the measurements will take place at RMIT University Chinese Medicine Research Laboratory. Waist circumference will be measured at the midpoint between the lower margin of the rib and the superior border of the iliac crest. Hip circumference will be measured from the widest point of the buttocks, and the measuring tape is to be kept parallel to the floor.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be randomised into three groups. The code will be placed in individually sealed opaque envelopes, which contains the information about the allocated treatment group. All participants will be selecting their envelope from the available envelopes and hand over to the researcher. The researcher will ensure that the envelope will not be opened until the name of the allocated participants is written on the envelope. Group assignments will not be changed after the allocation has made.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
An independent statistician will be responsible for generating simple randomisation code by using a computer program.
Masking / blinding

Efficacy
Statistical methods / analysis
Statistical analysis will be performed using Statistical Package for Social Science (SPSS) at the Discipline of Chinese Medicine, School of Health and Biomedical Science, RMIT University. Intention to Treat (ITT) analysis will also be performed for participants who are randomised and participated in at least 1 treatment session. Continuous variables will be summarised by using the mean, standard deviation, and 95% confidence intervals (CIs), while quantitative variables will be presented by using the maximum and minimum values. Baseline data and clinical characteristics will be used for comparing the baseline data between intervention groups. Analysis of covariance (ANCOVA) will be performed on BMI and WHR to determine the mean difference between groups.
