长期坐着，特别是看电视或视频，与多种疾病和死亡率的风险增加有关。然而，在美国，久坐行为随时间的变化还没有得到很好的描述。目的评估美国人群久坐行为的模式和时间趋势以及社会人口学和生活方式的相关性。对来自国家健康和营养调查（NHANES）的美国全国代表性数据的横断面分析在5至11岁的儿童中（2001-2016年）;青少年，12至19岁（2003-2016年）; 20岁或以上的成年人调查周期：主要结果和措施：每天坐着看电视或录像2小时或以上的流行率，每天在工作或学校以外使用电脑1小时或以上，以及总坐着的时间（h/d，年龄≥ 12岁）。（平均37.2岁[SE，0.19]; 25968 [50%]女性），包括10359名儿童，9639名青少年和31898名成人。在所有年龄段中，每天坐着看电视或视频2小时或以上的估计患病率都很高（儿童，62%[95% CI，57%至67%];青少年，59%[95% CI，54%至65%];成人，65%[95% CI，61%至69%]; 20-64岁成人，62%[95% CI，58%至66%];>= 65岁，84%[95%CI，81%至88%]（2015-2016年周期）。从2001年到2016年，随着时间的推移，儿童的趋势有所下降（差异，-3.4%<$95% CI，-11%至4.5%];趋势P = 0.004），由非西班牙裔白色儿童驱动;在青少年中稳定（-4.8%<$95% CI，-12%至2.3%];趋势P = 0.60）和20 - 64岁成人（-0.7%至95% CI，-5.6%至4.1%];趋势P = 0.82）;但在65岁或以上的成年人中增加（差异，3.5%[95% CI，-1.2%至8.1%];趋势P = 0.82）。03）。所有年龄段的儿童在校外或工作场所使用计算机1小时/天或以上的估计患病率从2001年至2016年增加了43%[95%CI，40%至46%]至56%[95%CI，49%至63%];差异为13%[95%CI，5.6%至21%];趋势P <0.001; 2003年至2016年，青少年为53%[95% CI，47%至58%]至57%[95% CI，53%至62%]，差异为4.8%[95% CI，-1.8%至11%];趋势P = 0.002;成人，2003年至2016年，29% [27%至32%]至50% [48%至53%]，差异，21% [95% CI，18%至25%];趋势P
IMPORTANCE Prolonged sitting, particularly watching television or videos, has been associated with increased risk of multiple diseases and mortality. However, changes in sedentary behaviors over time have not been well described in the United States.OBJECTIVE To evaluate patterns and temporal trends in sedentary behaviors and sociodemographic and lifestyle correlates in the US population.DESIGN, SETTING, AND PARTICIPANTS A serial, cross-sectional analysis of the US nationally representative data from the National Health and Nutrition Examination Survey (NHANES) among children aged 5 through 11 years (2001-2016); adolescents, 12 through 19 years (2003-2016); and adults, 20 years or older (2003-2016).EXPOSURES Survey cycle.MAIN OUTCOMES AND MEASURES Prevalence of sitting watching television or videos for 2 h/d or more, computer use outside work or school for 1 h/d or more, and total sitting time (h/d in those aged >= 12 years).RESULTS Data on 51 896 individuals (mean, 37.2 years [SE, 0.19]; 25 968 [50%] female) were analyzed from 2001-2016 NHANES data, including 10 359 children, 9639 adolescents, and 31 898 adults. The estimated prevalence of sitting watching television or videos for 2 h/d or more was high among all ages (children, 62%[95% CI, 57% to 67%]; adolescents, 59%[95% CI, 54% to 65%]; adults, 65%[95% CI, 61% to 69%]; adults aged 20-64 years, 62%[95% CI, 58% to 66%]; and >= 65 years, 84%[95% CI, 81% to 88%] in the 2015-2016 cycle). From 2001 through 2016, the trends decreased among children over time (difference, -3.4%[95% CI, -11% to 4.5%]; P for trend = .004), driven by non-Hispanic white children; were stable among adolescents (-4.8%[95% CI, -12% to 2.3%]; P for trend = .60) and among adults aged 20 through 64 years (-0.7%[95% CI, -5.6% to 4.1%]; P for trend = .82); but increased among adults aged 65 years or older (difference, 3.5%[95% CI, -1.2% to 8.1%]; P for trend =. 03). The estimated prevalence of computer use outside school or work for 1 h/d or more increased in all ages (children, 43%[95% CI, 40% to 46%] to 56%[95% CI, 49% to 63%] from 2001 to 2016; difference, 13%[95% CI, 5.6% to 21%]; P for trend < .001; adolescents, 53%[95% CI, 47% to 58%] to 57%[95% CI, 53% to 62%] from 2003 to 2016, difference, 4.8%[95% CI, -1.8% to 11%]; P for trend = .002; adults, 29% [27% to 32%] to 50% [48% to 53%] from 2003 to 2016, difference, 21% [95% CI, 18% to 25%]; P for trend
