- NCT05400187
- Lead Sponsor
- The Hong Kong Polytechnic University
- 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.

Group Intervention Description Body composition assessment and smart-phone based counselling group Body composition assessment and smart-phone based counselling In this study, we consider body composition measurement together with an immediate brief counselling after the measurement as part of the intervention. The body composition measurement will allow the participants to get familiar with their own anthropometric data and serve as cues to actions of healthy diet adoption and weight management and control. Based on the measured body fat and anthropometric data, a trained research assistant will give brief individualized dietary and weight management counselling to the participants. The Whatsapp-based counselling and communication will heighten the awareness through reinforcing the need and benefits of body composition and weight control, the importance of energy balance, as well as providing professional and tailor-made advice on healthy eating and weight management. Qualitative dietary counselling will be offered every two weeks through the Whatsapp.
- Primary Outcome Measures
Name Time Method The difference of the weight management knowledge 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 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.
- Secondary Outcome Measures
Name Time Method Weight From baseline to 6 months after randomization Weight in kg.
Body mass index (BMI) From baseline to 6 months after randomization BMI in kg/m\^2
Waist circumference From baseline to 6 months after randomization Waist in cm
Thigh circumference From baseline to 6 months after randomization Thigh in cm
The difference of health eating behavior From baseline to 6 months after randomization Respondents' food knowledge and behavior were obtained through the food behavior questionnaire (FBQ). The FBQ is a questionnaire with 18 questions querying respondents' behaviors and knowledge about various areas of food and diet-related health such as nutrition label reading behaviors, knowledge of diet/disease relationships and some meal consumption patterns.
Systolic blood pressure From baseline to 6 months after randomization Systolic blood pressure in mmHg
Diastolic blood pressure From baseline to 6 months after randomization Diastolic blood pressure in mmHg
Body fat mass From baseline to 6 months after randomization Body fat mass was measured by a professional body composition analyzer named InBody 270 in kg.
Hip circumference From baseline to 6 months after randomization Hip in cm
Body fat percentage From baseline to 6 months after randomization Body fat percentage was measured by a professional body composition analyzer named InBody 270 in %.
