简要总结
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 (brisk walking), 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.
详细描述
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) structured physical activity is brisk walking with 150 minutes minimum for target per week; (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.

研究组 & 干预措施
Worksite nutrition and wellness program
Participants receive a 12-week worksite nutrition and wellness program in a university setting. Core components include: (1) nutrition education sessions on healthy diet and portion control, (2) workplace-based wellness support and behavior-change strategies (e.g., goal setting and self-monitoring), and (3) physical activity component [e.g., brisk walking program/weekly targets]. Delivery mode: [group sessions/online messaging/face-to-face], frequency: [e.g., weekly/biweekly], and adherence support: [e.g., reminders, tracking, incentives if used]. Outcomes are assessed at baseline and post-intervention [plus interim assessments if applicable].
干预措施: Worksite Nutrition and Wellness Program (Behavioral)
Standard Education Group
Participants in this group will receive standard educational materials about nutrition and physical activity based on the official guidelines published by the Indonesian Ministry of Health. No structured or personalized intervention will be provided.
