Description of intervention(s) / exposure
The school-based health education and exercise program consists of eighteen 1-hour sessions which will be held on a weekly basis. The program is scheduled according to the school calendar, and there will be no sessions during exam period, special school events, and school holidays. The content of the program include 1) health education workshops (5 hours) on the benefits and basis knowledge about physical activity; 2) Fitness-walking exercise (3 hours) and 3) skill training sessions (10 hours) on skipping (for boys and girls), street dancing (for girls) and martial arts (for boys).

To encourage students' participation and adherence to the program, the program activities will be designed as team-based activities or games so students can learn in a fun and relaxing atmosphere. The activities are facilitated by instructors and coaches who are currently studying in college, and these "big brothers big sisters" will stand as a role model for the students. The research team will also work closely with the school teachers on any feedback throughout the program. Students who complete 80% of the program will be awarded with an attendance certificate.

Statistical methods / analysis
Descriptive statistics will be calculated for demographic characteristics, physical fitness test results, physical activty level, perceptions on physical activity. Data will be presented as mean (standard deviation), median (inter-quartile range) for skewed variables and frequency (percentage) as appropriate. A p-value less than 0.05 will be considered statistically significant. PASW Statistics 18 for Windows (formerly SPSS Statistics) (SPSS Inc., Chicago, IL, USA) will be used for statistical analysis.
