Design outcomes

Primary

Measure	Time frame
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

Measure	Time frame
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.	—
