To determine the patterns of computer usage among adolescents in Hong Kong and to examine whether computer usage is associated with less physical activity and social support among adolescents.
A total of 2110 secondary school students (52% boys and 48% girls) in Hong Kong completed a set of questionnaires to measure their computer usage and lifestyle. Mean age of the respondents was 14.16 years (SD = 1.81 years). Computer usage was taped by asking the students to indicate how much time (in minutes) they spent on the computer each day for doing homework assignments; playing computer games; "surfing" the Internet; and communicating with others. The students also provided information on their social-physical lifestyle. Student's t-tests and analysis of variance were used to examine group differences. Pearson product moment correlations were used to explore relationships between computer usage and lifestyle.
Boys who use computers for doing homework, "surfing" the Internet, and communicating with others engage in more social-physical activities than others. Boys who use computers to play games tend to be more social-behaviorally inactive. For girls, patterns of computer usage are not related to lifestyle.
Computer users tended to engage in social-physical activities more frequently and had higher social support than nonusers. But among computer users, the amount of time spent daily on the computer was not associated with lifestyle. Instead, patterns of computer usage are more related to lifestyle and the relationship is moderated by gender.
确定香港青少年的电脑使用模式，并研究电脑使用是否与青少年较少的身体活动和社会支持有关。
香港总共2110名中学生（52%为男生，48%为女生）完成了一组问卷，以测量他们的电脑使用情况和生活方式。受访者的平均年龄为14.16岁（标准差=1.81岁）。通过询问学生每天花多少时间（以分钟为单位）在电脑上做家庭作业、玩电脑游戏、“上网冲浪”以及与他人交流来记录电脑使用情况。学生们还提供了他们社交-身体生活方式的信息。使用学生t检验和方差分析来检验组间差异。使用皮尔逊积差相关来探索电脑使用与生活方式之间的关系。
使用电脑做家庭作业、“上网冲浪”以及与他人交流的男生比其他人参与更多的社交-身体活动。使用电脑玩游戏的男生往往在社交行为上更不活跃。对于女生来说，电脑使用模式与生活方式无关。
电脑使用者比非使用者更倾向于频繁参与社交-身体活动，并且有更高的社会支持。但是在电脑使用者中，每天花在电脑上的时间与生活方式无关。相反，电脑使用模式与生活方式更相关，并且这种关系受性别影响。
