| Summary: | 碩士 === 國立高雄師範大學 === 體育學系 === 101 === The purpose of this study was to evaluate the relationship and the differences of pedometer-determined physical activity and body mass index (BMI) between aboriginal and non-aboriginal children in the primary school. There were sixty-two aboriginal students (thirty-six males, twenty-six females) of the primary school in the Pingtung County and fifty-four non-aboriginal volunteered students (twenty-four males, thirty females) of the primary school in the Kaohsiung City enrolled. The participants accepted the measurements of the height and weight to obtain the results of BMI, and wore sealed pedometers for consecutive 4 schooldays to determine the physical activity. Independent T-test was used to test the differences of pedometer-determined physical activity and BMI of aboriginal and non-aboriginal students, and used the Pearson’s correlation to discuss the relationship between pedometer-determined physical activity and BMI of aboriginal and non-aboriginal students. The results are: 1. There were significant differences of mean daily steps between aboriginal and non-aboriginal female students (aboriginal: 13354±3457 , non-aboriginal: 10689±2059 , p＜.001), but no significant difference was noted between males. 2. There were no significant differences of mean daily steps between male and female aboriginal students, and so were between non-aboriginal students. 3. There were significant correlation between pedometer-determined physical activity and BMI of all participants (p＜.05), and so were of aboriginal students (p＜.05), but no significant correlation was noted in non-aboriginal students. The conclusions are: 1. Female aboriginal students have significantly more pedometer-determined physical activity and BMI than female non-aboriginal students. 2. There were significant correlations between pedometer-determined physical activity and BMI of aboriginal students.
