Overview
Brief Summary
This study proposed an integrated multi-disciplinary approach including a professional and convenient body composition measurement and an immediate counselling after the measurement, followed by 6-month smart-phone based individualized counselling. We believe that this approach will promote healthy eating behaviors and weight management among middle-aged Chinese in Hong Kong.
Detailed Description
This is a two-arm, individual level, 6-month randomized controlled trial. The intervention group will receive convenient body composition measurement and 6-month smart-phone based individualized counselling. No specific intervention will be given to the control group except the common anthropometric and body composition measurement. A pretest-posttest evaluation and between-group comparison will be used to test whether the impact/success of the project has been achieved.

Outcomes
Primary Outcomes
The difference of the weight management knowledge
Time Frame: From baseline to 6 months after randomization
The knowledge of weight management was measured by 13 items from the general nutrition knowledge questionnaire (GNKQ). Each item carries one point for a correct answer and the maximum score is 13. A higher score shows better weight management knowledge.
The difference of the weight management belief
Time Frame: From baseline to 6 months after randomization
Four items from belief domain of Chinese weight management scales (WMS) was used to measure the participants' belief of self weight management . Each item is measured by 3- or 4-point Likert scale. The total score change from 4 to 15 with higher scores indicating better weight management belief.
