久坐行为被认为是与体力活动不同的一个概念，久坐行为对健康的影响与体力活动水平无关。儿童久坐行为的一个主要来源是看电视或电影、玩视频游戏和使用电脑。迄今为止，还没有研究探讨邻里社会经济地位（SES）对学龄前儿童的屏幕时间行为的影响。 2005 年 11 月至 2007 年 8 月期间，艾伯塔省埃德蒙顿市的 1633 位家长为其 4-5 岁的孩子完成了工作日和周末屏幕时间（电视/电影、视频游戏和电脑使用）的代理报告。邮政编码用于将社区分为低、中或高 SES。采用多重线性和逻辑回归模型来检验屏幕时间和邻里社会经济地位之间的关系。与生活在社会经济地位高社区的女孩相比，生活在社会经济地位低社区的女孩每周看屏幕的时间和看电视/电影的时间要多得多。在男孩中没有观察到同样的关系。与生活在社会经济地位高社区的儿童相比，生活在社会经济地位低社区的儿童更有可能成为视频游戏用户，而不太可能成为计算机用户。此外，与生活在高社会经济地位社区的儿童相比，生活在中等社会经济地位社区的儿童成为计算机用户的可能性明显较低。应考虑为儿童，特别是生活在社会经济地位较低社区的女孩提供替代活动机会。此外，未来的研究应该继续调查社区社会经济地位对屏幕时间的独立影响以及这种关系的潜在中介变量。
Sedentary behavior is considered a separate construct from physical activity and engaging in sedentary behaviors results in health effects independent of physical activity levels. A major source of sedentary behavior in children is time spent viewing TV or movies, playing video games, and using computers. To date no study has examined the impact of neighborhood socioeconomic status (SES) on pre-school children's screen time behavior. Proxy reports of weekday and weekend screen time (TV/movies, video games, and computer use) were completed by 1633 parents on their 4-5 year-old children in Edmonton, Alberta between November, 2005 and August, 2007. Postal codes were used to classified neighborhoods into low, medium or high SES. Multiple linear and logistic regression models were conducted to examine relationships between screen time and neighborhood SES. Girls living in low SES neighborhoods engaged in significantly more weekly overall screen time and TV/movie minutes compared to girls living in high SES neighborhoods. The same relationship was not observed in boys. Children living in low SES neighborhoods were significantly more likely to be video game users and less likely to be computer users compared to children living in high SES neighborhoods. Also, children living in medium SES neighborhoods were significantly less likely to be computer users compared to children living in high SES neighborhoods. Some consideration should be given to providing alternative activity opportunities for children, especially girls who live in lower SES neighborhoods. Also, future research should continue to investigate the independent effects of neighborhood SES on screen time as well as the potential mediating variables for this relationship.
