Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to evaluate the effectiveness of a worksite-based nutrition and wellness program in improving body composition, metabolic profile, and physical fitness among university employees who are overweight or obese. The intervention includes personalized and structured physical activity (such as Zumba classes), nutritional education, and self-monitoring using mobile applications. Participants will be assessed at baseline, after 6 weeks and 12 weeks of intervention to determine changes in fat mass, muscle mass, waist circumference, and related health indicators. This program is designed to promote healthier lifestyle habits and prevent non-communicable diseases in the workplace.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is cluster randomized controlled trial conducted at Universitas Brawijaya to assess the effectiveness of a comprehensive workplace-based wellness intervention. The intervention comprises three key components: (1) personalized physical activity based on GPAQ and structured physical activity, including biweekly group Zumba sessions and home-based sessions using video guidance; (2) personalized nutrition education delivered through interactive counseling; and (3) daily self-monitoring using a mobile application.

Participants include university employees categorized as overweight or obese, who work in sedentary office jobs for more than 5 hours per day. Subjects will be assessed at three time points-baseline, after 6 weeks, and after 12 weeks-to measure changes in body composition (e.g., body mass index, body fat percentage, subcutaneous fat, skeletal mass, and waist circumference), metabolic profile (e.g., fasting blood glucose and cholesterol), and physical fitness parameters.

The study aims to provide evidence on the impact of structured, low-cost wellness programs in reducing obesity-related health risks among adult employees in institutional settings. Ethical approval has been obtained from the Faculty of health, Universitas Brawijaya. The results are expected to support future implementation of health promotion policies in the workplace.
