運動量與電視觀賞量對學童身體質量指數之影響

Abstract

本研究之目的在探討電視觀賞及運動量之多寡與身體質量指數(BMI)之關係，以期建立兒童有益健康之正確生活習性。以問卷及面談的方式調查台北市三興國小高年級學童（男童三百零五人，女童二百八十七人，１０－１５歲）的電視觀賞量、運動量與身高、體重。結果發現：在五、六年級學童中，性別對BMI之影響大於年齡所造成之影響。男童之運動量也較女童者顯著為高(P<0.05)。電視觀賞量則五年級女童較五年級男童及六年級男、女童顯著為低（p<0.05）；然而五年級男童及六年級男、女童間則無差異。BMI過重者則發現其運動量顯著為低(P<0.05)，但其電視觀賞量雖略多但與BMI正常及過輕者無分軒轅。本研究結果建議：宜多增加學童之運動量或戶外活動量。並適度減少電視觀賞量以期預防學童肥胖及慢性疾病之發生。

This study was conducted to investigate the influence of exercise and television viewing on the body mass index (BMI) of Taipei Shan-Shing Elementary School children (305 boys and 287 girls, 10-15 yr.). On an interview basis, data of body weight, height, and the time of exercise and television viewing were collected with a questionnaire. The BMI of 5th and 6th grade children were significantly affected by the gender (P<0.05) but not the age. The exercise time of the school boys was significantly higher than that of the school girls (P<0.05). The television viewing time of the 5th grade girls was significantly lower than those of other school children (P<0.05) investigated in this study. There was no significant difference in the television viewing time among the 5th grade boys and 6th grade boys and girls. The exercise time of the heavy children (BMI> mean+ S. D.) was significantly lower than those of other children (P<0.05). The television viewing time of these heavy children was numerically higher than others, although it did not reach the statistically significant difference. Therefore, in order to prevent the obesity and chronic disease, the outdoor activity and exercise time should be increased, and the time of television and video viewing should be decreased for our children.
