儿童肥胖的高患病率强调了监测儿童活动和屏幕时间的人口趋势以及描述与儿童年龄，性别，种族/民族和体重状况的关联的重要性。我们的目标是估计美国儿童中活跃游戏水平低或屏幕时间高或两者兼而有之的比例，并描述与年龄，性别，种族/民族和体重状况的关联。我们分析了2001-2004年国家健康和营养调查中收集的数据，这是一项具有全国代表性的横断面研究。我们研究了2964名4.00至11.99岁的儿童。我们的主要结果是每周报告的时间，孩子玩或锻炼足够努力出汗或呼吸困难（主动游戏），每天小时，孩子看电视/视频，使用电脑，或玩电脑游戏（屏幕时间），以及低主动游戏和高屏幕时间的组合。低活跃游戏被定义为每周活跃游戏6次或更少。高筛选时间定义为每天超过2小时。我们在分析和报告比例以及95%置信区间中考虑了复杂的调查设计。我们使用Wald卡方检验比例之间的差异。为了确定与低活跃游戏和高屏幕时间相关的因素，我们使用了多变量logistic回归。在4至11岁的美国儿童中，37.3%（95%置信区间，34.1%至40.4%）的主动游戏水平较低，65.0%（95% CI，61.4%至68.5%）的屏幕时间较高，26.3%（95% CI，23.8%至28.9%）的儿童同时具有这两种行为。与同时具有低活跃游戏和高屏幕时间的较高概率相关的特征是年龄较大、女性、非西班牙裔黑人种族/民族以及年龄BMI ≥ CDC生长参考的第95百分位数。据报道，美国许多幼儿的身体活动和屏幕时间行为与健康儿科发育的建议不一致。超重的儿童、接近青春期的儿童、女孩和非西班牙裔黑人可能从针对这些行为的公共卫生政策和计划中受益最多。
The high prevalence of childhood obesity underscores the importance of monitoring population trends in children's activity and screen time, and describing associations with child age, gender, race/ethnicity, and weight status. Our objective was to estimate the proportion of young children in the US who have low levels of active play or high levels of screen time, or who have both these behaviors, and to describe associations with age, gender, race/ethnicity, and weight status. We analyzed data collected during the National Health and Nutrition Examination Surveys 2001–2004, a US nationally representative cross-sectional study. We studied 2964 children aged 4.00 to 11.99 years. Our main outcomes were reported weekly times that the child played or exercised hard enough to sweat or breathe hard (active play), daily hours the child watched television/videos, used computers, or played computer games (screen time), and the combination of low active play and high screen time. Low active play was defined as active play 6 times or less per week. High screen time was defined as more than 2 hours per day. We accounted for the complex survey design in analyses and report proportions and 95% confidence intervals. We used Wald Chi-square to test for differences between proportions. To identify factors associated with low active play and high screen time, we used multivariate logistic regression. Of US children aged 4 to 11 years, 37.3% (95% confidence interval, 34.1% to 40.4%) had low levels of active play, 65.0% (95% CI, 61.4% to 68.5%) had high screen time, and 26.3% (95% CI, 23.8% to 28.9%) had both these behaviors. Characteristics associated with a higher probability of simultaneously having low active play and high screen time were older age, female gender, non-Hispanic black race/ethnicity, and having a BMI-for-age ≥95th percentile of the CDC growth reference. Many young children in the US are reported to have physical activity and screen time behaviors that are inconsistent with recommendations for healthy pediatric development. Children who are overweight, approaching adolescence, girls, and non-Hispanic blacks may benefit most from public health policies and programs aimed at these behaviors.
