Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This research project aims to find out if a newly developed context specific mobile phone application can help these sedentary employees to improve their lifestyle. The app, called m-LIfE (mHealth-based Lifestyle Intervention for Employees), will be designed to help employees to move more during the day and eat healthier food like fruits and vegetables.
The study will involve bank employees in urban Karachi, Pakistan. They will be divided into two arms:
Intervention arm: Participants in this arm will use the m-LIfE app for 12 weeks. They will get reminders and tips to take breaks, exercise, and eat healthy.
Routine care arm: Participants in this arm will receive printed basic educational material about prevention of risk factors of heart diseases and improving lifestyle.
After the 12 weeks of intervention, there will be a follow-up period at 4th week to check if participants are maintaining healthy habits.
This study could help find simple and affordable ways to improve the health of office workers and reduce pressure on the healthcare system.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The banking sector in particular has been facing a tremendous change for several years due to the increasing number of new entrants, which has increased competition among the banks. Economic uncertainties and political instability have also affected the industry and consequently the health outcomes of its employees who are considered high risk urban sedentary workers as they spend more than 8 hours of their daytime sitting with minimal physical activity (PA) and consuming high lipid diet. This behavior predisposes them to CVD unless they take preventive health behaviors (engage in regular PA, increase fruit and vegetable intake, and reduce fatty meals, sugar, and salt intake). Lifestyle modification aimed at improving PA and dietary habits is the first-line approach to reducing cardiovascular risk. However, the feasibility of implementing such strategies in urban environments needs to be examined. Currently, little is known about which intervention components would be most effective in improving the lifestyle behaviors of bank employees.
Pertinently, the workspaces of most bank branches in Pakistan lack suitable areas for relaxation or PA, further exacerbating the sedentary nature of their work. Consequently, this high-risk group requires targeted efforts to increase their knowledge and address their lifestyle behaviors for effective CVD prevention. Therefore, the development and testing of strategies specifically tailored to this occupational group are of utmost importance.
The overall aim of this research project is to develop and assess the feasibility of m-LIfE (mHealth-based Lifestyle Intervention for Employees) to improve lifestyle in high-risk urban sedentary employees (bank employees) from Karachi, Pakistan. The specific objectives are (1) To explore awareness (perception and preferences) about CVD and its prevention among high-risk sedentary employees, and design m-LIfE (2) To assess feasibility of m-LIfE versus routine care among high-risk sedentary employees. The secondary objective is to report potential efficacy on lifestyle (PA and dietary intake) in both m-LIfE and routine arm.
This study will employ a mixed-methods approach, beginning with an exploratory qualitative phase and followed by a pilot cluster randomized controlled trial (cRCT). The qualitative component will explore awareness, perceptions, and preferences regarding CVD and its prevention. Following this, m-LIfE app will be developed using human centered design approach.
The pilot cRCT will evaluate the feasibility and potential efficacy of the m-LIfE over a 12-week intervention period, with a 4-week follow-up. Eight clusters (bank branches) will be randomly selected out of 313 branches across Karachi, out of which four will be randomized to the m-LIfE intervention, and four clusters will serve as the routine care arm. The study will be conducted in branches of three commercial banks (one public and two private) located in urban Karachi, Pakistan.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
m-LIfE
Participants in the intervention arm will receive mHealth application (m-LIfE). The application will be installed on participants' personal mobile phones, and each participant will be provided with a unique user ID and password.
m-LIfE: mobile based lifestyle intervention for employees to increase their physical activity and promote healthy diet.
The m-LIfE will primarily deliver healthy lifestyle educational content, provide customized strategies for PA, and offer participants the option to enter their daily intake of fruits and vegetables through Food Log feature. m-LIfE will track PA and diet, send tailored reminders, and provide motivational messages. Participants will receive two text messages daily: a goal reminder in the morning and feedback or reflection on their progress in the evening. Additionally, they will receive one motivational message at the end of each week to sustain their motivation. Personalized feedback will also be provided through the application, featuring graphs to illustrate daily, weekly, and monthly progress.
To support participants further, the application will enable two-way communication, allowing users to seek assistance and ask questions from the research team. A dedicated contact number will be made available within the app to facilitate direct communication.
Routine care arm
Participants in the routine care arm will receive basic educational material in the form of paper-based pamphlets without any active intervention by the study team.
Routine care arm
Participants in the routine care arm will receive educational material in the form of paper-based pamphlets to ensure they still benefit from basic health information on CVD risk prevention. They will continue their usual work routines without access to the app, but their PA and dietary habits will be assessed at baseline, post-intervention and at follow-up for comparative purposes.
