Clinical Trial Summary

The study aims to compare the effect of a lifestyle intervention programme (LIP) using mobile application (MetS app) vs using booklet for MetS adults living in the community.

Description:

The study aims to compare the effect of a lifestyle intervention programme (LIP) using mobile application (MetS app) vs using booklet for MetS adults living in the community.

Methods A multi-site randomized controlled trial (RCT) with three arms, namely, MetS app group (Group A), booklet group (Group B), and control group (group C). Three hundred and sixty subjects will be recruited from six community centers and randomized into either one arm. Inclusion criteria are those MetS adult, able to use a smart phone. Group a participants will receive a 30-minute educational session and a MetS app while Group B will receive same educational session and a MetS booklet and the control group receive a placebo booklet only. The MetS app or booklet, has been well developed by the team with the support of internal grant, aims to support MetS individual's self- monitoring and record of health measures (body weight, blood pressure, waist circumference) and exercise. The primary outcomes of this study include the body weight and total physical exercise (GSLTPAQ). The secondary outcomes include cardiometabolic risk factors, cardiovascular endurance, self-efficacy for exercise (SEE) and stress level (PSS-10). Data will be collected at baseline (T1), 4 week (T2) and week 12 (T3) and week 24 (T4). SPSS and Generalized Estimating equations (GEE) model will be employed for data analysis.

Significance This study will provide empirical evidence and inform about the effective way to enhance patient's self-management of MetS, exercise sustainability that will be beneficial to clients' health.

• Syndrome

Intervention

Other:
• App group
Intervention group the participants will receive a Lifestyle Intervention Program (LIP) with the support of MetS mobile application (MetS app). The MetS app support include app installment and briefing by a research assistant after the educational talk. The participants can view the similar knowledge content related to metabolic syndrome in their own smart phone. In addition, a membership area provides individual support of self- health monitoring, goal setting of exercise plan and exercise record. A user guide of the MetS app will be provided to the participants to take home after the briefing.
• Booklet group
The participants will additionally receive a Hong Kong version LIP booklet to take home and use for 24 weeks. The major component of the LIP booklet consists of fact of metabolic syndrome, advise of diet, exercise, medication, life style and stress management.
• control group
Participants will be advised to maintain their usual activities. They will additionally receive a placebo health leaflet. The health leaflets are produced by Department of Health and commonly distributed to the general public. For the ethical reason, those control group participants are freely to receive the LIP booklet after completion of the study at 24 weeks.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Body weight	change in body weight will be measured at the same scale in the follow up centre	24 weeks
Secondary	Total physical exercise	Total physical exercise will be quantified with a modified version of the GSLTPAQ [31-32]. The patients will be instructed to indicate the amount of exercises undertaken and rank the exercises in the order of difficulty (strenuous, moderate, or mild). The total score will be calculated. This measure has been widely used in empirical studies and shown to exhibit good Psychometric properties [31-32]	24 weeks
Secondary	Chinese version of Self-Efficacy for Exercise (SEE-C)	The SEE-C consists of nine items, and responses are made on a 0-10 scale. The sum of the responses to all nine items yields the final composite score ranging from 0-90. The C-SE has been proved to be reliable with good psychometric properties of Cronbach's alpha coefficient 0.75 for Taiwan Chinese older adults [33-34].	24 weeks
Secondary	Cardiovascular endurance test.	it is a three -minute step test to test the cardiovascular functional endurance after exercise across the age span and gender. A participant step on and off of a 12 inch high bench / or stair for 3 minutes. Then pulse will be taken afterward while the participant remain standing. Compare the heart rate with the table according to the age and gender to determine the fitness in a range of 7 score from excellent, good, above average, average, below average, poor and very poor . Validity of this test has been established in previous studies. [35] .	24 weeks
Secondary	Perceived stress scale (PSS-10)	Ten self-report items measure the degree to which situations in one's life are appraised as stressful and the current levels of experienced stress in the last month. Summative scores range from 0 to 40, with a higher score indicating higher stress level. These scores have been used as outcome measures of experienced levels of stress. The psychometric properties of the Chinese version of PSS-10 were satisfactory with Cronbach's alphas >0.75 in a local study for Chinese cardiac patients. [36]	24 weeks
Secondary	hospitalization	hospitalization frequency will be asked	24 weeks
Secondary	app usage	MetS app usage (frequency per week) will be collected by RA by retrieving the data from the app server for the intervention group monthly.	24 weeks
Secondary	booklet usage	Booklet usage (frequency per week) will be collected for the control group at baseline, week 4,12 and 24	24 weeks
Secondary	Waist circumference (cm)	The Waist circumference is measured by a trained RA with a tape (cm) at the midpoint between the top of the iliac crest and the lower margin of the last rib in the standing position at the end of several consecutive natural breaths	24 weeks
Secondary	blood pressure	Systolic and diastolic blood pressure (mmHg) is measured by a trained RA using same equipment. Data will be collected by RA	24 weeks
Secondary	Lipid level	A drop of blood sample will be taken by using a finger stick to measure LDL cholesterol (mmol/L), and HDL cholesterol (mmol/L), and triglycerides (mmol/L). The data can be analysed immediately by using auto-analyser and the participants are asked to have 8 hours fasting. Data will be collected by RA	24 weeks
Secondary	Fasting blood glucose	Fasting blood glucose level (mmol/L) : the participants are asked to have 8 hours fasting before blood taken. A drop of blood will be collected by finger stick by RA using same glucometer to measure the fasting blood glucose level	24 weeks
