背景/目的久坐行为（SB）包括运动和姿势两个部分，但大多数SB研究仅评估低运动，尤其是儿童。本研究的目的是比较估计和健康协会的SB时，来自一个标准的加速度计临界点，一种新的坐着检测技术（CNN髋关节加速度计Poetry儿童; CHAP儿童），两者结合。MethodsData来自国际儿童肥胖研究，生活方式，和环境（ISCOLE）。参与者为来自12个国家的6103名儿童（平均值± SD，年龄10.4 ± 0.56岁），他们在右髋关节上佩戴ActiGraph GT 3X+加速计约一周。我们计算SB时间，平均SB发作持续时间，SB休息使用一个临界点（SB运动），CHAP儿童（SB姿势），和两种方法相结合（SB组合）。混合效应回归用于检验SB变量与儿童肥胖变量的相关性结果在调整MVPA后，SB结果显示了几个显著的肥胖相关性，有利于较低的平均SB回合持续时间（B= 0.251-0.449; allp< 0.001）和较高的SB断裂（B= −0.005-−0.052; allp< 0.001）。总SB较低与肥胖程度较高出乎意料地相关（B= −0.077-−0.649;pfrom <0.001-0.02）。对于平均SB回合持续时间和SB休息，更多的协会观察到SB姿势（n= 5）比SB运动（n= 3）或SBcombined（n= 1），并往往有较大的幅度，以及.ConclusionsUsing传统的措施，低运动作为替代SB可能会导致低估或未被发现的不良关联SB和肥胖之间。CHAP-儿童允许使用臀部佩戴的加速度计评估坐姿。需要持续的工作来了解低运动和姿势是如何相互关联的，以及它们对健康的潜在影响。
Background/ObjectivesSedentary behavior (SB) has both movement and postural components, but most SB research has only assessed low movement, especially in children. The purpose of this study was to compare estimates and health associations of SB when derived from a standard accelerometer cut-point, a novel sitting detection technique (CNN Hip Accelerometer Posture for Children; CHAP-Child), and both combined.MethodsData were from the International Study of Childhood Obesity, Lifestyle, and the Environment (ISCOLE). Participants were 6103 children (mean ± SD age 10.4 ± 0.56 years) from 12 countries who wore an ActiGraph GT3X+ accelerometer on the right hip for approximately one week. We calculated SB time, mean SB bout duration, and SB breaks using a cut-point (SBmovement), CHAP-Child (SBposture), and both methods combined (SBcombined). Mixed effects regression was used to test associations of SB variables with pediatric obesity variables (waist circumference, body fat percentage, and body mass index z-score).ResultsAfter adjusting for MVPA, SBpostureshowed several significant obesity associations favoring lower mean SB bout duration (b= 0.251–0.449; allp< 0.001) and higher SB breaks (b= −0.005–−0.052; allp< 0.001). Lower total SB was unexpectedly related to greater obesity (b= −0.077–−0.649;pfrom <0.001–0.02). For mean SB bout duration and SB breaks, more associations were observed for SBposture(n= 5) than for SBmovement(n= 3) or SBcombined(n= 1), and tended to have larger magnitude as well.ConclusionsUsing traditional measures of low movement as a surrogate for SB may lead to underestimated or undetected adverse associations between SB and obesity. CHAP-Child allows assessment of sitting posture using hip-worn accelerometers. Ongoing work is needed to understand how low movement and posture are related to one another, as well as their potential health implications.
