目的：我们假设，屏幕使用时间越长，心理问题越严重，屏幕娱乐使用时间越长、体育活动时间越少的儿童的心理状况最负面。方法：研究对象为1013名儿童（年龄，平均+/- SD: 10.95 +/- 0.41岁），他们自我报告每天平均看电视时间和电脑使用时间，并完成优势和困难问卷。使用加速度计测量久坐时间（每天分钟，= 2000 cpm）。多元回归模型检验了电视观看、电脑使用、久坐时间和优势与困难问卷得分之间的关系，并对MVPA、年龄、性别、剥夺程度和青春期状态进行了调整。结果：在调整MVPA、久坐时间和混杂因素后，更多的电视和电脑使用与更高的心理困难得分有关。然而，久坐时间与调整后的心理困难呈负相关。每天看电视或使用电脑2小时的儿童患高水平心理障碍的风险增加（看电视，比值比[or]: 1.61[95%可信区间[CI]: 1.20-2.15]；用电脑，比值比[or]: 1.59 [95% CI: 1.32-1.91]），如果儿童也不遵守体育活动指南（看电视，比值比：1.70 [95% CI: 1.09-2.61]；用电脑，比值比：1.81 [95% CI: 1.02-3.20]），这种风险增加。结论：无论MVPA水平或整体久坐时间如何，看电视和使用电脑都是儿童最佳健康干预的重要独立目标。儿科2010;126: e1011-e1017
OBJECTIVE: We hypothesized that greater screen use would be associated with greater psychological difficulties and that children with high levels of screen entertainment use and low levels of physical activity would have the most-negative psychological profiles.METHODS: Participants were 1013 children (age, mean +/- SD: 10.95 +/- 0.41 years), who self-reported average daily television hours and computer use and completed the Strengths and Difficulties Questionnaire. Sedentary time (minutes per day with = 2000 cpm) were measured by using accelerometers. Multivariate regression models examined the association between television viewing, computer use, sedentary time, and Strengths and Difficulties Questionnaire scores, with adjustment for MVPA, age, gender, level of deprivation, and pubertal status.RESULTS: Greater television and computer use were related to higher psychological difficulty scores after adjustment for MVPA, sedentary time, and confounders. However, sedentary time was inversely related to psychological difficulties after adjustment. Children who spent >2 hours per day watching television or using a computer were at increased risk of high levels of psychological difficulties (television, odds ratio [OR]: 1.61 [95% confidence interval [CI]: 1.20-2.15]; computer, OR: 1.59 [95% CI: 1.32-1.91]), and this risk increased if the children also failed to meet physical activity guidelines (television, OR: 1.70 [95% CI: 1.09-2.61]; computer, OR: 1.81 [95% CI: 1.02-3.20]).CONCLUSION: Both television viewing and computer use are important independent targets for intervention for optimal well-being for children, irrespective of levels of MVPA or overall sedentary time.
