LANGUAGE NOTE | Document text in English; abstract also in Chinese.

The purpose of the study was to examine if the levels of physical activity predict the number of hours of computer use among pupils of healthy body weight from primary and secondary schools in Singapore. 120 primary school participants (mean age: 10.6 yrs) and 120 secondary school participants (mean age: 18.8 yrs), with the appropriate consents were involved in the study. Information number of hours of computer use, computer accessibility, how it is used for work and leisure and self-reported levels of current physical activity was gleaned from questionnaire responses Results showed that the number of hours spent per week using the computer increased with age (6.0±5.0 vs. 8.6±7.7 hrs, p<0.05), computer accessibility was very high (above 90%). No meaningful associations were detected among weekly number of hours of computer use and self reported levels of current physical activity, except for a small but significant correlation between hours of computer use and self-reported physical activity levels (r=0.23, p<0.05) in normal weight primary school participants. The results of the present study showed that the levels of current physical activity among primary and secondary pupils of healthy weight were not negatively associated with the weekly number of hour of computer use.

本文對240名正常體重的中小學生(120名小學生，平均年齡為10.6歲和120名中學生，平均年齡為18.8歲)每周電腦使用時數、電腦普及程度、在學習和業餘時間如何使用電腦以及體育活動的水平進行了問倦調查，其目的是探討新加坡中小學生的體育活動水平是否可預測其使用電腦時間的長短。研究結果顯示，每周電腦使用時數的增加與年齡有關，小學生與中學生分別為6.0±5.0小時和8.6±7.7小時(p<0.05)，電腦普及率高達90%以上。每周電腦使用時數與體育活動水平之間無明顯的關系，雖然在小學生中二者之間有統計學意義(r=0.23，p<0.05)。本研究結果表明了在正常體重的中小學生中，體育活動的水平與電腦使用周時數之間無顯箸性負相關。
