发育性协调障碍（DCD）是一种神经发育障碍，其特征在于精细和/或粗大运动协调不良。假设患有DCD的儿童由于运动协调问题而不活动导致超重和肥胖的风险增加。虽然以前的研究已经找到了支持这一假设的证据，但他们依赖基于现场的测量，最明显的是身体质量指数（BMI），以确定身体成分是有问题的。此外，迄今为止还没有研究检查是否有协调和不协调的儿童之间的瘦肉组织质量存在差异。肌肉质量的差异，瘦肉组织的主要组成部分，可能是协调问题和超重和肥胖的发展的一个促成因素，但在这个时候只是间接检查。在这项研究中，使用双腔体积描记器进行全身排气，以估计可能患有DCD（pDCD）的儿童和一组典型发育儿童的脂肪量、去脂肪量和体脂。与先前使用基于现场的相对体重评估的研究一致，结果表明，pDCD儿童的体脂比同龄人高得多，并且这种差异随着观察到的运动协调困难的严重程度而增加。两组间的瘦肉组织质量无差异。使用更敏感的身体成分测量方法证明pDCD和体脂之间存在关联，并且有证据表明这种关系存在剂量反应，进一步支持DCD可能是儿童肥胖的风险因素的假设。(C)2010爱思唯尔有限公司保留所有权利。
Developmental coordination disorder (DCD) is a neuro-developmental disorder characterized by poor fine and/or gross motor coordination. Children with DCD are hypothesized to be at increased risk for overweight and obesity from inactivity due to their motor coordination problems. Although previous studies have found evidence to support this hypothesis, their reliance on field-based measures, most notably body mass index (BMI), to determine body composition is problematic. Moreover, there has been no research to date that has examined whether THERE ARE differences in lean tissue mass between children with and without coordination. Differences in muscle mass, the main component of lean tissue, may be a contributing factor to both coordination problems and the development of overweight and obesity, but has only been indirectly examined at this time. In this study, whole-body air displacement using a dual chamber plethysmograph was used to estimate fat mass, fat free mass and body fat in children with probable DCD (pDCD) and a group of typically developing children. Consistent with previous research using field-based assessments of relative body weight, the results show that children with pDCD have much higher body fat than their peers, and that this difference increases with the severity of observed motor coordination difficulties. There was no difference in lean tissue mass between groups. The demonstration of an association between pDCD and body fat using a more sensitive measure of body composition, and evidence showing a dose-response in this relationship, further supports the hypothesis that DCD may be a risk factor for obesity in children.
