■24小时运动指南(24-HMG)建议采用平衡的身体活动(PA)组合,久坐行为(SB)和睡眠(SLP)以获得最佳健康。然而,对美国青少年遵守这些指南的程度的了解有限.这项研究旨在分析在具有全国代表性的美国普通青少年样本中满足24-HMG的患病率趋势。
■该研究包括2007年至2016年参加国家健康和营养调查(NHANES)的2,273名16-19岁青少年(55.3%的男孩)。研究人员根据青少年是否遇到各种PA进行分类,SB,和SLP建议,以及这些建议的不同组合,分别为男孩和女孩。患病率,按调查数据加权,计算了95%置信区间(CI),以评估不同调查年份和社会人口统计学亚组中美国青少年在满足24-HMG方面的变化。
■在2015-2016年周期中,大约6.3%的青少年没有达到三项建议中的任何一项,而只有19.2%的青少年达到了这三个指导方针。青少年对PA和SB建议的依从性随着时间的推移而下降,PA从72.5%(65.9%到79.2%)到64.2%(57.4%到70.9%),SB从59.0%(49.6%到68.4%)到46.6%(37.8%到55.5%),分别,从2007-2008周期到2015-2016周期。与女孩相比,男孩在满足不同的建议方面表现出更有利的模式(p值<0.001)。这包括符合PA和SB指南(男孩为15.5%,女孩为11.1%),以及符合PA和SLP指南(男孩为19.5%,女孩为15.7%)。发现父母的教育水平对满足所有三个指南都有影响(Ptrend<0.05)。
■我们分析了连续十年的代表性NHANES数据,以评估24-HMG的患病率会议,发现美国16-19岁青少年中同时遵守所有三项运动指南的比例在每个调查周期中一直保持在较低水平。值得注意的是,符合SB指南的青少年比例显著下降.
The 24-Hour Movement
Guidelines (24-HMG) recommend a balanced combination of physical activity (PA), sedentary behavior (SB) and sleep (SLP) for optimal health. However, there is limited understanding of how well U.S. adolescents adhere to these
guidelines. This study aims to analyze the prevalence
trends of meeting the 24-HMG among a nationally representative sample of U.S. general adolescents.
The study included 2,273 adolescents (55.3% boys) aged 16-19 who participated in the National Health and Nutrition Examination Surveys (NHANES) from 2007 to 2016. The researchers categorized the adolescents based on whether they met various PA, SB, and SLP recommendations, as well as different combinations of these recommendations, separately for boys and girls. The prevalence rate, weighted by survey data, was calculated along with a 95% confidence interval (CI) to assess the changes in meeting the 24-HMG among U.S. adolescents across different survey years and sociodemographic subgroups.
In the 2015-2016 cycle, approximately 6.3% of adolescents did not meet any of the three recommendations, while only 19.2% of adolescents achieved all three guidelines. Compliance with PA and SB recommendations among adolescents has decreased over time, from 72.5% (65.9% to 79.2%) to 64.2% (57.4% to 70.9%) for PA, and from 59.0% (49.6% to 68.4%) to 46.6% (37.8% to 55.5%) for SB, respectively, from 2007-2008 cycle to 2015-2016 cycle. Boys exhibited more favorable patterns in meeting different sets of recommendations compared to girls (p-value <0.001). This includes meeting both PA and SB guidelines (15.5% for boys and 11.1% for girls) and meeting both PA and SLP
guidelines (19.5% for boys and 15.7% for girls). The level of parental education was found to have effect on meeting all three guidelines (Ptrend < 0.05).
We analyzed ten consecutive years of representative NHANES data to evaluate the prevalence meeting 24-HMG and found that the proportion of adolescents aged 16-19 in the U.S. who adhered to all three movement guidelines simultaneously has consistently remained low throughout each survey cycle. Notably, there has been a significant decline in the proportion of adolescents meeting the SB
guideline.
