简要总结
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.
详细描述
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.

盲法说明
During the randomization session, the generated random numbers will be placed in opaque and tamperproof envelopes and sealed. Another independent person (other than statistician) will open all envelopes for eligible participants and responsible for arranging participants to undertake their corresponding treatments. Participants, investigators, and statistician will be concealed about the random allocation until each participant has been registered and the assignments have been made. The research assistant who will perform the outcome measures and the statistician are blinded to treatment group assignment.

结局指标
主要结局
The difference of the weight management knowledge
时间窗: 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
时间窗: 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.
