| Scientific title | Childhood obesity management shifting from healthcare system to school system: school-based weight management programme |
| Study objectives | To evaluate the effectiveness of a multi-component school-based weight management programme that aimed to help primary school children with overweight and obesity to achieve the goal of weight control via a home-school joint venture supported by healthcare professionals. |
| Ethics approval(s) | This project was funded by the Health Care Promotion Fund of the Hong Kong Government Food and Health Bureau. The proposal was approved by the Committee of Health Care Promotion Fund (Project 20060524) based on quality standard of the proposal including ethical standard with membership from government, academics and non-government organisations. |
| Health condition(s) or problem(s) studied | Overweight and obesity of primary care students |
| Intervention | 57 students were randomly selected to participate in the school based programme first with 49 students as wait list control who started the programme. Students attended ten 75-minutes after-school sessions and one 3-hour weekend session of practical, interactive and fun activities on healthy eating and exercise. Students were provided a meal plan at the beginning of the programme together with parents and received printed tailor-made management advices. Parents received an introductory seminar with two sets of specially designed exercise for overweight children and further two 1-hour follow up sessions on skills about healthy eating and exercise strategies to assist weight control for their children. |
| Intervention type | Behavioural |
| Primary outcome measure | The primary study outcomes were age- and sex-adjusted BMI (BMI z-score) and body fat percentage. Body weight (to nearest 0.1kg) and body fat percentage (to nearest 0.5%) were measured by bio-impedance body fat scale (Model: TBF-521, Tanita, Japan) with participants lightly clothed and without shoes. Standing height (to the nearest cm) was measured with a portable stadiometer (Model: 214, SECA). Outcome measures were assessed at baseline (T0) before the intervention, and completion of 4-month intervention (T1) to assess the immediate program effectiveness and after a 4-month maintenance period (8 months from baseline, T2) to evaluate the sustainability of the programme. |
| Secondary outcome measures | Secondary outcomes include self-reported attitude and behavioural variables. Students completed a set of questionnaire adopted from previous studies specially designed for school children containing a total of 20 items to investigate the attitude towards healthy eating and exercise, dietary behaviour, physical activity participation, self-control, self-perception and weight management practice. Parents completed a self-administered questionnaire on the general health condition, eating and exercise habit of their children, cooking methods used at home, frequencies of engaging in different activities (such as housework, outings and sports activities) with their children. |
