Effectiveness of a Lifestyle Intervention Programme Using Mobile Application vs Booklet for Adult With Metabolic Syndrome
The Effectiveness of a Lifestyle Intervention Programme Using Mobile Application vs Booklet for Adult With Metabolic Syndrome _ a Pilot Study
Aims This Pilot study aims to develop and determine the feasibility and acceptability of a mobile application (MetS app) together with a modified Life style modification Program (LIP) for soon-to-aged adults with metabolic syndrome (MetS) and to determine the sample size for the main RCT. .
Methods A prospective randomized control trial design with process evaluation will be adopted. Inclusion criteria are those MetS participants, age 45 or above, able to use a smart phone. A total of eighty eligible participants will be recruited from 2-3 community Centres. Control group will receive standard care while intervention group will receive a MetS app. Standard care consists of a modified three-month lifestyle modification booklet, a 30 minutes educational session. The intervention group will receive a 30 minute education session plus MetS support, which will be guided by health belief model to support an individual self- monitoring and record of health measures (body weight, blood pressure, waist circumference) and physical exercise (goal setting of exercise and record) across three months. All information from the LIP booklet are also installed in the MetS platform as well. The primary outcomes will be waist measure and the total physical exercise (GSLTPAQ). The secondary outcomes included cardio-metabolic risk factors, cardiovascular endurance, self-efficacy for exercise (SEE) and stress level (PSS-10) and quality of Life (SF12). Data will be collected at baseline, one-month (T1) and three-month (T2). SPSS version 23 and Generalized Estimating equations (GEE) model will be employed to examine the effects of the LIP with MetS app support.
Panoramica dello studio
Descrizione dettagliata
Background Educational programme intervention on Lifestyle modification is recommended as the primary intervention for metabolic syndrome (MetS), a cluster of cardio-metabolic risk factors with a high prevalence rate globally and locally. Recent studies of lifestyle intervention program (LIP) have been reported as effective on physical indicators and quality of life (QoL) among MetS adult. However, they have the challenges in the delivery in making care scalable and little is known about the effect on exercise outcomes such as total exercise, cardiovascular endurance after exercise as well as whether the outcomes of this programme can be applied in Hong Kong and improved by adding the mobile application.

Significance This pilot study will provide insights to guide the main study. The findings will facilitate the development of MetS app that could support the self-efficacy for physical health monitoring and exercise of patients with MetS. Such programme may enhance patient's self-management and monitoring of MetS, exercise behavior sustainability that will be beneficial to reduced MetS risk profile, and improves psychological health and quality of life.

Comparatore attivo: 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.

Comparatore attivo: 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.

Change in total physical exercise
Lasso di tempo: baseline, 1 month and 3 months
|
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.

change in Cardiovascular endurance test.
Lasso di tempo: baseline, 3 mobnths
|
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.

Change in Perceived stress scale (PSS-10)
Lasso di tempo: baseline, 1 month and 3 months
|
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.
