Introduction

Children with motor coordination problems are at increased risk for both sedentary behaviour and internalizing problems relative to their typically developing peers; however, the relationship between motor coordination, internalizing problems, and sedentary behaviour is not well understood. The purpose of this study was to examine the moderating role of sedentary behaviour on the relationship between motor coordination and anxiety/depression scores in children at risk for Developmental Coordination Disorder and a sample of typically developing children.

Methods

Data for the present study were derived from the Coordination and Activity Tracking in CHildren (CATCH) cohort study. 507 children aged 4–5 years (219 girls, 288 boys, mean age: 59.3 months) were classified as typically developing (>16th percentile) or at risk for DCD (≤16th percentile) based on Movement Assessment Battery for Children 2nd edition scores. Sedentary and physical activity behaviour were measured using an Actigraph GT3X+ activity monitor device. Parent-reported Child Behaviour Checklist (CBCL) scores were used to assess internalizing problems (i.e. anxiety/depression).

Results

Multiple linear regression (moderation) analysis showed sedentary behaviour significantly moderated the relationship between motor coordination and anxiety/depression scores after adjusting for sex, socioeconomic status and physical activity behaviour, ΔR² = 0.01, F (1, 500) = 4.31, p = .038. Johnson-Neyman technique revealed children at risk for DCD begin to report significantly higher anxiety/depression scores when their sedentary behaviour is at least 0.27 h per day above the group mean (M = 7.52 h/day).

Conclusion

Above average levels of sedentary behaviour exacerbate internalizing problems among children at risk for DCD. Interventions should focus on incorporating strategies to reduce sedentary behaviour in order to buffer anxiety/depressive symptoms for children with poor motor coordination.

久坐行为与有无运动协调障碍儿童内在化问题的关联

介绍

相对于典型的同龄人，运动协调问题的儿童久坐行为和内在化问题的风险增加。但是，对运动协调，内在问题和久坐行为之间的关系了解得很少。这项研究的目的是研究久坐行为对处于发展性协调障碍风险的儿童以及典型发育中儿童的运动协调与焦虑/抑郁评分之间关系的调节作用。

方法

本研究的数据来自儿童的协调和活动跟踪（CATCH）队列研究。根据《儿童运动评估电池》第二版评分，将507位4-5岁的儿童（219名女孩，288名男孩，平均年龄：59.3个月）分类为典型发育中（> 16％）或有DCD风险（≤16％）。 。使用Actigraph GT3X +活动监控器测量久坐和身体活动行为。父母报告的儿童行为清单（CBCL）分数用于评估内部化问题（即焦虑/抑郁）。

结果

多元线性回归（中度）分析显示，在调整了性别，社会经济地位和身体活动行为后，久坐行为显着缓解了运动协调与焦虑/抑郁评分之间的关​​系，ΔR ²  = 0.01，F（1，500）= 4.31，p  = .038。Johnson-Neyman技术揭示了有DCD风险的儿童，当他们的久坐行为每天比团体平均水平高出至少0.27小时（M  = 7.52 h / day）时，他们开始表现出明显更高的焦虑/抑郁评分。

结论

久坐的行为高于平均水平会加剧有DCD风险的儿童的内在化问题。干预措施应侧重于采取减少久坐行为的策略，以减轻运动协调不良儿童的焦虑/抑郁症状。
