The number of single-child families has been rising steadily in recent years, resulting in a childhood absent of sibling relationships. Being an only child has been shown to have a negative impact on physical fitness, somatic fitness, and motor development. In this study, we aimed to understand how living with and without siblings can impact the motor competence of children. One hundred and sixty-one children (87 boys, 74 girls) from 3.0 to 6.0 years of age (34 only children, 125 siblings) and with no known motor or cognitive disability were assessed using the Motor Competence Assessment (MCA). Their standardized results on the three MCA subscales (stability, locomotor, and manipulative) and total MCA were used to group them into high, average, and low motor competence groups. Motor competence percentile distribution of the sibling and only child group condition was compared using chi-square tests. Results showed a significative and positive association between the sibling condition and the distribution between the three MC groups (chi-square = 6.29; = 0.043), showing that children in a household with siblings, independent of their age and sex, show a clear tendency for developing better motor competence.
近年来，独生子女家庭的数量一直在稳步上升，导致孩子们的童年缺乏兄弟姐妹关系。研究表明，独生子女身份对身体健康、体能和运动发展有负面影响。在本研究中，我们旨在了解有无兄弟姐妹的生活环境如何影响儿童的运动能力。我们使用运动能力评估（MCA）对161名3.0至6.0岁的儿童（87名男孩，74名女孩）进行了评估，这些儿童无已知的运动或认知障碍（其中34名独生子女，125名有兄弟姐妹）。他们在MCA三个分量表（稳定性、移动性和操作性）以及MCA总分上的标准化成绩被用于将他们分为高、中、低运动能力组。使用卡方检验比较有兄弟姐妹组和独生子女组的运动能力百分位数分布。结果显示，兄弟姐妹状况与三个运动能力组之间的分布存在显著正相关（卡方=6.29；P=0.043），表明有兄弟姐妹的家庭中的孩子，无论年龄和性别，都表现出运动能力发展更好的明显趋势。
