Study arms

• Active comparator
  mobile app

  Mobile app: The participants will receive a Life style Modification Program with the support of mobile application (MetS app). The participants can view the similar knowledge content related to metabolic syndrome in their own smart phone. In addition, a membership area of the Mets app 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 app installment and briefing.

  Other: mobile application

• Active comparator
  booklet

  The participants will receive the Life Style Modification programme with the support of a Hong Kong version Metabolic Syndrome (MetS) booklet to take home and use for 3 months. The booklet had been modified from a booklet of a Life Style Intervention Programme (LIP) in China and the principal investigator of this proposal was the core team members of the previous project . The booklet content covers 26 pages about the metabolic syndrome and risk factors, suggested life style modification tips in terms of exercise, diet, smoking, mediation and stress management . The major component of the booklet for the change is the language translated from simplified Chinese to traditional Chinese and slight adjustment about the advice on vegetable choice due to difference in type of available vegetables in Hong Kong.

Primary outcomes

1. Change in body weight

   body weight weighted at the same scale by the research assistant (RA) in the follow up

   Time frame: 1 month and 3 months

2. Change in total physical exercise

   Total physical exercise quantified with a modified version of the GSLTPAQ \[31-32\]. The patients were instructed to indicate the amount of exercises and to rank the exercises in the order of difficulty (strenuous, moderate, and mild). Total physical exercise will be computed by summing up the total number of sessions per week multiplied by minutes per session. The scale has been widely used in empirical studies and it has been shown to have good psychometric properties with acceptable test-retest reliability (ranged from 0.62 to 0.81), and correlated with maximum oxygen consumption, treadmill time and other similar physical activity questionnaire. \[31-32\].

   Time frame: baseline, 1 month and 3 months

Secondary outcomes

1. Change in 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

   Time frame: baseline, 1 month and 3 months

2. change in 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. \[35\] .

   Time frame: baseline, 3 mobnths

3. Change in 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. \[36\]

   Time frame: baseline, 1 month and 3 months

4. Hospitalization frequency

   Recent hospitalization frequency (number of hospitalization visit and hospitalization in last three month) will be asked by Research assistant (RA) at baseline and at 3 months.

   Time frame: baseline, 3 months

5. Mets app usage frequency

   MetS app usage (frequency per week) will be collected by RA by retrieving the data from the app server for the intervention group

   Time frame: monthly till 3 month

6. Booklet usage frequency

   Booklet usage (frequency per week) will be collected for the control group at baseline, 1month and 3 months.

   Time frame: baseline, 1 month and 3 months

7. 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. Data will be collected at baseline, 1month and 3 months.

   Time frame: baseline, 1 month and 3 months

8. Blood pressure (mmHg)

   Systolic and diastolic blood pressure (mmHg) is measured by a trained RA using same equipment. Data will be collected at baseline, 1month and 3 months.

   Time frame: baseline, 1month and 3 months.

9. Lipid level (mmol/L)

   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 at baseline, 1month and 3 months.

   Time frame: baseline and 3 months

10. 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 at baseline, 1month and 3 months.

    Time frame: baseline, 1 month and 3 months
