To date, it remains unclear whether young children at risk for developmental coordination disorder (DCD) develop deficits in physical activity participation, and the relationship between motor competence (MC) and physical activity (PA) in these children.
To evaluate the levels of MC and PA in young children at risk for DCD (rDCD) and to explore the relationship between these two aspects.
A total of 124 children with rDCD and 124 typically developing (TD) children aged 3-6 years were selected. Each group included 85 boys and 39 girls. MC was evaluated using the Movement Assessment Battery for Children-2 and the Test of Gross Motor Development-third edition. PA was assessed using the Questionnaire of Parents of Physical Activities of Young Children. MC variables were manual dexterity, aiming and catching, balance, and locomotor skills. PA variables were total PA (TPA), moderate to vigorous PA (MVPA) and sedentary behavior (SB).
Children with rDCD had significantly lower scores in manual dexterity, aiming and catching, balance, and locomotor skills compared with TD children (P < 0.05). There was no difference in TPA, MVPA and SB between children with rDCD and TD overall (P > 0.05). Balance, aiming and catching, and locomotor skills in children with rDCD were weakly positively correlated with MVPA (r = 0.197-0.347, P < 0.05). Balance, aiming and catching, and locomotor skills in children with rDCD significantly predicted MVPA (β= 0.219-0.342, P < 0.05).
Young children at risk for DCD do not yet show deficits in physical activity participation. It is still important to develop motor competence in young children at risk for DCD, as this may help them sustain participation in physical activity and avoid early withdrawal.
迄今为止，发育性协调障碍（DCD）风险儿童是否在身体活动参与方面存在缺陷，以及这些儿童的运动能力（MC）与身体活动（PA）之间的关系仍不明确。
评估发育性协调障碍风险儿童（rDCD）的运动能力和身体活动水平，并探讨这两个方面之间的关系。
共选取124名3至6岁的发育性协调障碍风险儿童和124名发育正常（TD）儿童。每组包括85名男孩和39名女孩。使用儿童运动评估量表第二版和粗大运动发育测试第三版评估运动能力。使用幼儿身体活动家长问卷评估身体活动。运动能力变量包括手动灵巧性、目标瞄准和接球、平衡以及运动技能。身体活动变量包括总身体活动（TPA）、中度至剧烈身体活动（MVPA）和久坐行为（SB）。
与发育正常儿童相比，发育性协调障碍风险儿童在手动灵巧性、目标瞄准和接球、平衡以及运动技能方面的得分显著更低（P<0.05）。发育性协调障碍风险儿童与发育正常儿童在总身体活动、中度至剧烈身体活动和久坐行为方面总体无差异（P>0.05）。发育性协调障碍风险儿童的平衡、目标瞄准和接球以及运动技能与中度至剧烈身体活动呈弱正相关（r=0.197-0.347，P<0.05）。发育性协调障碍风险儿童的平衡、目标瞄准和接球以及运动技能显著预测了中度至剧烈身体活动（β=0.219-0.342，P<0.05）。
发育性协调障碍风险儿童在身体活动参与方面尚未表现出缺陷。对于发育性协调障碍风险儿童而言，发展运动能力仍然很重要，因为这可能有助于他们持续参与身体活动并避免过早退出。
