背景:满足24小时运动行为(24-HMB:身体活动[PA],屏幕时间[ST],andsleep[SL])recommendationsmaybeassociatedwithpositivehealthoutcomesamongyouthwithspecificmental,行为,和神经发育(MBD)条件。然而,在这些高危人群中,满足24-HMB指南的时间趋势和差异尚未得到调查,阻碍循证临床和公共卫生干预措施的发展。
方法:串行,我们对全国儿童健康全国调查(NSCH)数据(包括美国6-17岁患有MBD疾病的青少年)进行了横断面分析.时间趋势调查数据是在2016年至2021年之间进行的。报告了整个样本和各种社会人口统计学亚组的24-HMB依从性估计的患病率。分析的亚组包括:年龄组(儿童[6至13岁],青少年[14至17岁]),性别,社会经济地位,和种族。
结果:52,634人的数据(平均年龄,12.0年[SD,3.5];28,829[58.0%]男孩)进行了分析。从2016年到2021年,符合PA+ST+SL指南的估计趋势下降(-0.8%[95CI,-1.0%至-0.5%],趋势P<0.001),而符合24-HMB指南的指标均无增加(2.2%[1.8%至2.6%],趋势P<0.001)。白人参与者,孩子们,和男孩报告较高的估计患病率符合完全综合(PA+ST+SL)指南。
结论:本研究中观察到的时间趋势强调了持续监测MBD青年的运动行为并确定社会人口统计学群体的差异对于满足24-HMB在这些弱势群体中促进健康的指南的重要性。
BACKGROUND: Meeting 24-h movement behaviors (24-HMB: physical activity [PA], screen time [ST], and sleep [SL]) recommendations may be associated with positive health outcomes among youth with specific mental, behavioral, and neurodevelopmental (MBD) conditions. However, temporal trends and disparities in meeting 24-HMB guidelines in these higher-risk groups have not been investigated, hampering the development of evidence-based clinical and public health interventions.
METHODS: Serial, cross-sectional analyses of nationally National Survey of Children\'s Health (NSCH) data (including U.S. youth aged 6-17 years with MBD conditions) were conducted. The time-trends survey data was conducted between 2016 and 2021. The prevalence of 24-HMB adherence estimates were reported for the overall sample and for various sociodemographic subgroups. The subgroups analyzed included: age group (children[aged 6 to 13 years], adolescents[aged 14 to 17 years]), sex, socioeconomic status, and ethnicity.
RESULTS: Data on 52,634 individuals (mean age, 12.0 years [SD,3.5]; 28,829 [58.0 %] boys) were analyzed. From 2016 to 2021 the estimated trend in meeting PA + ST + SL guidelines declined (-0.8 % [95%CI, -1.0 % to -0.5 %], P for trend <0.001), whereas meeting none of 24-HMB guidelines increased (2.2 % [1.8 % to 2.6 %], P for trend <0.001). White participants, children, and boys reported higher estimated prevalence of meeting full integrated (PA + ST + SL) guidelines.
CONCLUSIONS: The temporal trends observed in this study highlight the importance of consistently monitoring movement behavior among MBD youth and identifying variations by sociodemographic groups in meeting 24-HMB guidelines for health promotion within these vulnerable groups.
