目的：对2000-2001年加拿大社区健康调查中12-19岁的青少年(12-19岁)进行久坐活动(使用电脑、玩电子游戏、看电视和阅读)时间与缺乏运动的关系进行评估。方法：研究样本包括加拿大7982名青少年(男4034人，女3948人)(平均年龄15.61岁，SD：2.23岁)。每周在闲暇时间花在电脑、电子游戏、电视和阅读上的时间是通过自填式问卷获得的。缺乏体力活动是由受访者通过体力活动问卷评估的每日能量消耗确定的。多因素Logistic回归分析分别按性别检验久坐活动与体力活动缺乏之间的关系。分析中控制了社会人口学变量、健康状况和超重状况。结果：相当大比例的加拿大青年不活跃：50.3%的男性和67.8%的女性。控制了社会人口统计变量、健康状况和体重指数，无论男性还是女性，看电视都与身体缺乏活动显著相关，无论他们的超重状况如何。然而，在男性中，电脑使用与体力活动相关，在女性中，阅读与体力活动相关。结论：久坐行为与身体不活动之间存在复杂的相互关系，这突显了针对久坐行为参与模式的有针对性的干预的必要性。减少看电视的时间可能是减少年轻人缺乏体育活动的干预措施中的一个看似合理的策略。(C)2006年青少年医学会。版权所有。
Purpose: To evaluate the relationships between the time spent on sedentary activities (computer usage, video game playing, television viewing, and reading) and physical inactivity in a sample of youth (aged 12-19 years) from the 2000-2001 Canadian Community Health Survey.Methods: The study sample included 7982 youth (4034 males, 3948 females) across Canada (mean age: 15.61 years, SD: 2.23 years). Weekly time spent on computers, video games, television, and reading during leisure-time was obtained through self-reported questionnaires. Physical inactivity was determined by respondents' daily energy expenditure assessed through a physical activity questionnaire. Multivariate logistic regression analysis was conducted to examine the relationship between sedentary activities and physical inactivity respectively by gender. Sociodemographic variables, health status, and overweight status were controlled in the analysis.Results: A substantial proportion of Canadian youth was inactive: 50.3% of males and 67.8% of females. Controlling for sociodemographic variables, health status, and body mass index, television viewing was significantly associated with physical inactivity for both males and females regardless of their overweight status. However, computer usage was associated with physical activity among males, and reading was associated with physical activity among females.Conclusions: There is a complex inter-relationship between sedentary behaviors and physical inactivity, highlighting the need for targeted interventions addressing patterns of sedentary behavior engagement. Reducing time spent on television viewing may be one plausible strategy within such interventions in reducing physical inactivity among youth. (c) 2006 Society for Adolescent Medicine.
