BACKGROUND
Research has linked excessive television viewing and computer use in children and adolescents to a variety of health and social problems. Current recommendations are that screen time in children and adolescents should be limited to no more than 2 h per day.
OBJECTIVE
To determine the percentage of Canadian youth meeting the screen time guideline recommendations.
METHODS
The representative study sample consisted of 6942 Canadian youth in grades 6 to 10 who participated in the 2001/2002 World Health Organization Health Behaviour in School-Aged Children survey.
RESULTS
Only 41% of girls and 34% of boys in grades 6 to 10 watched 2 h or less of television per day. Once the time of leisure computer use was included and total daily screen time was examined, only 18% of girls and 14% of boys met the guidelines. The prevalence of those meeting the screen time guidelines was higher in girls than boys.
CONCLUSION
Fewer than 20% of Canadian youth in grades 6 to 10 met the total screen time guidelines, suggesting that increased public health interventions are needed to reduce the number of leisure time hours that Canadian youth spend watching television and using the computer.
背景
研究表明，儿童和青少年过度看电视及使用电脑与多种健康和社会问题相关。目前的建议是，儿童和青少年的屏幕使用时间应限制在每天不超过2小时。
目的
确定符合屏幕使用时间指南建议的加拿大青少年的比例。
方法
具有代表性的研究样本包括6942名6至10年级的加拿大青少年，他们参与了2001/2002年世界卫生组织学龄儿童健康行为调查。
结果
6至10年级中，只有41%的女孩和34%的男孩每天看电视时间为2小时或更少。一旦将休闲电脑使用时间纳入并检查每日总屏幕使用时间，只有18%的女孩和14%的男孩符合指南。符合屏幕使用时间指南的比例女孩高于男孩。
结论
6至10年级的加拿大青少年中，不到20%的人符合总屏幕使用时间指南，这表明需要加强公共卫生干预措施，以减少加拿大青少年在休闲时间看电视和使用电脑的时长。
