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.
