The 24-hour movement behaviours, including sleep, sedentary behaviour (SB), and moderate-to-vigorous physical activity (MVPA) are crucial for a child's healthy growth and development. Yet, the full 24-hour movement behaviour composition has not been thoroughly explored in children with suspected Developmental Coordination Disorder (sDCD). The aim of this study was to compare the 24-hour movement behaviour compositions of children with sDCD to their typically developing (TD) peers and to assess the associations between movement behaviours and motor competence. Sixty-nine children (mean age 8.6 ± 1.6 years, 55% boys) wore a wrist-mounted accelerometers for seven consecutive days, completed a dynamic motor competence assessment and were screened for sDCD using the Developmental Coordination Disorder Questionnaire. Results of the compositional Isotemporal-substitution analysis indicated that children with sDCD spent less time in light physical activity (LPA) and MVPA and more time in SB compared to the TD group. No significant differences were observed during school or weekend periods. However, increasing MVPA in place of lower-intensity activities was associated with theoretical improvements in motor competence. The 24-hour movement behaviour profiles of children with sDCD identified in this study may have adverse implications for their future health and wellbeing, emphasising the need for targeted interventions, particularly during out-of-school hours.
包括睡眠、久坐行为（SB）和中度至剧烈身体活动（MVPA）在内的24小时运动行为，对儿童的健康成长和发育至关重要。然而，对于疑似发育协调障碍（sDCD）的儿童，尚未对其完整的24小时运动行为构成进行全面探究。本研究的目的是比较sDCD儿童与发育正常（TD）同龄人之间的24小时运动行为构成，并评估运动行为与运动能力之间的关联。69名儿童（平均年龄8.6±1.6岁，55%为男孩）连续七天佩戴腕式加速度计，完成动态运动能力评估，并使用发育协调障碍问卷对sDCD进行筛查。成分等时替代分析结果表明，与TD组相比，sDCD儿童进行轻度身体活动（LPA）和MVPA的时间较少，而进行SB的时间较多。在上学期间或周末期间未观察到显著差异。然而，用增加MVPA来替代低强度活动与运动能力的理论改善相关。本研究中确定的sDCD儿童的24小时运动行为特征可能对其未来的健康和幸福产生不利影响，这凸显了针对性干预的必要性，尤其是在课外时间。
