本研究的目的是利用一项基于大规模人群的研究数据，检验以下假设：可能患有发育协调障碍的儿童中度至剧烈体力活动 (MVPA) 减少的风险增加。雅芳家长和儿童纵向研究 (ALSPAC) 前瞻性收集了 4331 名儿童（男孩 = 2065，女孩 = 2266）的数据，这些儿童在 7 岁时完成了运动协调测试，并在 12 岁时完成了加速度测量。使用基于 DSM IV 分类的标准，将可能的 DCD (p-DCD) 定义为 7 岁时 ALSPAC 协调测试 15% 以下且日常生活或书写活动有功能障碍的儿童，不包括已知神经系统诊断或智商 < 70 的儿童。次要暴露变量包括 ALSPAC 协调测试的子测试（手动灵活性、球技能和平衡）。使用活动记录仪加速计，客观测量 MVPA 的平均每日分钟数，记录为每分钟 >= 3600 次计数 (cpm)。患有 p-DCD 的男孩比没有 DCD 的男孩身体活动较少（MVPA 平均差异为 4.36 cpm，t=2.69；p = 0.007）。对于男孩来说，在调整包括新生儿、家庭和环境因素以及 7 岁和 12 岁时体重指数在内的混杂因素后，目标技能（抛豆袋）与 MVPA 增加相关（β = 0.76，t = 3.37，p < 0.001，Cl 0.32-1.20）。患有和不患有 p-DCD 的女孩的 MVPA 水平没有差异（平均差 1.35 分钟，t = 0.97，p = 0.31），这可能反映了该队列中女孩的 MVPA 水平较低。我们的研究结果表明，年轻时存在运动困难，特别是瞄准能力差（抛豆袋/球技能）是男孩 MVPA 降低的潜在风险因素。 (C) 2011 Elsevier Ltd. 保留所有权利。
The aim of the current study was to test the hypothesis that children with probable Developmental Coordination Disorder have an increased risk of reduced moderate to vigorous physical activity (MVPA), using data from a large population based study. Prospectively collected data from 4331 children (boys = 2065, girls = 2266) who had completed motor coordination testing at 7 years and accelerometry at 12 years were analysed from the Avon Longitudinal Study of Parents and Children (ALSPAC). Probable DCD (p-DCD) was defined, using criteria based on the DSM IV classification, as those children below the 15th centile of the ALSPAC Coordination Test at seven years who had a functional impairment in activities of daily living or handwriting, excluding children with a known neurological diagnosis or IQ < 70. Secondary exposure variables consisted of subtests from the ALSPAC Coordination test (manual dexterity, ball skills and balance). Objective measurement of the average daily minutes of MVPA was recorded as >= 3600 counts per minute (cpm) using actigraph accelerometry. Boys with p-DCD were less physically active than boys without DCD (mean difference in MVPA 4.36 cpm, t=2.69; p = 0.007). For boys, targeting skill (bean bag toss) was related to increased MVPA, after adjustment for confounding factors including neonatal, family and environmental factors as well as Body Mass Index at age seven and 12 years (beta = 0.76, t = 3.37, p < 0.001, Cl 0.32-1.20). There was no difference in level of MVPA in girls with and without p-DCD (mean difference 1.35 min, t = 0.97, p = 0.31), which may reflect the low levels of MVPA of girls in this cohort. Our findings suggest that the presence of movement difficulties, particularly poor targeting (bean bag toss/ball skills), at a young age is a potential risk factor for reduced MVPA in boys.
