　　本研究旨在了解高中生身體活動量的現況，以及身體活動量與身體質量指數、腰圍、腰臀比及體脂肪的相關性。本研究之受試者為高雄市某高中79位平均16.88±0.28歲的高二學生，男生共44人、女生共35人。受試者須接受身高、體重、腰圍、臀圍及皮脂厚度的測量，並於上學日配戴計步器連續四天，測量每日步數。以獨立樣本T檢定，檢測不同性別受試者每日平均步數的差異；身體活動量與身體質量指數 (body mass index, BMI)、腰圍、腰臀比與體脂肪的相關性以Pearson相關係數檢定；並以單因子變異數分析 (one-way ANOVA)，檢定不同身體活動量分組之身體質量指數、腰圍、腰臀比與體脂肪的差異性。研究結果：男生每日平均步數為8,676±3,005步、女生為8,020±2,144步（p= .28）；身體活動量與身體質量指數、腰圍及體脂肪有顯著負相關（r= -.248，p=.028；r= -.225，p=.047；r= -.258，p=.022，p < .05），與腰臀比則沒有相關性（r= -.133，p=.241）；將受試者平均步數由低至高做三等分分組發現三組之身體質量指數、腰圍、腰臀比與體脂肪皆無顯著差異（p > .05）。本研究結論為高中生的身體活動量低於建議量；不同性別的身體活動量無顯著差異、身體活動量與身體質量指數、腰圍及體脂肪有負相關，與腰臀比無顯著相關、不同身體活動量分組之身體質量指數、腰圍、腰臀比及體脂肪沒有顯著差異。

The purpose of this study was to investigate the status of high school student’s physical activity (PA) and the correlation between PA and body mass index (BMI), waist circumference (WC), waist-hip ratio (WHR) and body fat percentage (%BF). Subjects in this study were 79 senior high school students in Kaohsiung with an average age of 16.88 ± 0.28. There were 44 boys and 35 girls. Subject’s height, weight, WC, hip circumference and skinfold thickness for %BF calculation wer measured. Pedometers were worn on school days for four consecutive days to measure the PA (daily steps). PA (average daily steps) were analyzed by using Independent-Sample T test between genders; Pearson’s product-moment correlation coefficient was used to explore the relationship between PA and BMI, WC, WHR and %BF; and one-way ANOVA was used to explore the difference of BMI, WC, WHR and %BF among different PA groups. Results: There was no significant difference in PA between boys and girls. The average number of steps per day for boys was 8,676 ± 3,005 steps and for girls was 8,020 ± 2,144 steps (p = .28). There was a negative correlation between PA and BMI, WC and %BF (r = -.248, p = .028; r = -.225, p = .047; r = -.258, p = .022, p <.05), and no correlation with WHR (r = -.133, p = .241). The subjects was divided into three groups according to the PA level and found no significant difference in BMI, WC, WHR and %BF (p> .05) among three groups. The results of this study showed that there was no significant difference in PA between high school boys and girls. PA was negatively correlated with BMI, WC and %BF, and had no significant correlation with WHR. BMI, WC, WHR and %BF had no significant difference among different level of PA groups.
