The epidemic problem of physical inactivity and sedentary lifestyle development came to global alert for which worldwide organizations like WHO and UNESCO worked together towards the development of
strategies in overcoming this problem in society. The focus of global works went to the next generation as study indicated the importance of childhood’s experiences in physical activity and their
habit of participation has tremendous effect to their life development as adolescent, youth and in adulthood. Direccao dos Servicos de Educacao e Junventudfe (DSEJ) of Macau SAR government also
recognized the problem with decision to launch an experimental project of Fitness Award Scheme at 10 primary schools in 2008. The project was later adopted a new title of Active Kid 123 in 2011 and
promoted to all primary schools in Macau. The recent development renamed the project to Active 123 (Primary) and Active 123 (Secondary) in early 2015 when the first participated students group reached
the high school age. The current investigation followed the same class groups from 10 experimental primary schools since 2008 until 2013. Students’ height and weight, relationship with BMI and
discussion on possible strategies in helping students to get move are the focus of concern in this study.
The present study collected data on students’ height and weight and their BMI figures through DSEJ’s health project of Active Kid 123 from 2008 to 2013 in Macau. A total of 5369 primary school
students (3368 male and 2001 female) at the age of 6 to 11 participated in this study.
To interpret the calculation descriptive statistics such as mean, standard deviation was used. Further, to compare the data gender and yearwise independent t-test was implemented. Finally, to compute
the categories of BMI (such as Underweight Standard, Overweight and Obesity) person Chi square test was used. To know students’ mass of the body in relation to height and weight, their BMI (Body Mass
Index) were measured and categorized under four perspectives of Underweight, Standard Weight, Overweight and Obese in according to the norm as currently used in Taiwan Region. The finding indicated
higher BMI level among the male students then the female students across all the age categories (2008 t = 5.24, 2009 t = 88.25, 2010 t = 11.32, 2011 t = 17.45, 2012 t = 19.70 and 2013 t = 19.92 at .05
level of significance) and the age of 8 to 9 seemed to be the disrupted period for raise of overweight and obesity.
The message indicated a trend of higher chance for male students to be overweight and obese with a disrupted period at the age of 8 to 9. Female students are less to be affected with the disrupted
period to happen in a latter age. Focused works with suitable intervention activities on different period seem to be important strategy in helping students to get move.
