DESCRIPTION (provided by applicant): The long-term goals of this project are to identify factors that contribute to inadequate physical activity in children with Developmental Coordination Disorder (DCD) and to develop interventions to promote physical activity and reduce health risk. Lack of adequate physical activity is a significant health problem in children in the United States. While considerable efforts are underway to understand and address the problem of low physical activity levels in the general population, there has been little research in children with disabilities. We propose that children with DCD are at particular risk for low activity, low levels of fitness and obesity due to the nature of their disorder. DCD is a neurologically-based developmental disorder characterized by impaired motor coordination that significantly interferes with academic achievement and activities of daily living. Because of poor coordination, children with DCD often are unable to participate in sports and physical activities with their peers. The goals of this study are to test our overarching hypothesis that children with DCD are less active, more sedentary, and thus are at greater risk for obesity and lower levels of fitness than children with adequate motor coordination. We will examine if the association of participation in physical activity and time spent in sedentary behavior with fitness and with weight status differs between children with DCD and with adequate motor coordination. We will use state-of-the-art methodology to measure activity level (accelerometry). We will determine whether children with DCD show significantly lower overall activity, spend less time in moderate-vigorous activity and more time in sedentary behavior, have significantly lower levels of physical fitness and significantly higher BMI z-scores and prevalence of risk for obesity (>85th percent), than children with average motor coordination. The relationship among measures will be examined to understand whether physical activity in children with DCD has the same effect on weight status and fitness as in children with adequate coordination. This project is responsive to Healthy People 2010 objectives which seek to increase physical activity among the nation's youth. Children with DCD represent a substantial number of children in the population who, due to their coordination disorders, are at even higher risk. The study has broader implications to other children with special needs such as those with learning disabilities and autism who also have been identified as having coordination deficits that may limit participation.

描述(由申请者提供)：该项目的长期目标是确定导致发育协调障碍(DCD)儿童体力活动不足的因素，并制定干预措施，以促进体力活动和降低健康风险。缺乏足够的体力活动是美国儿童的一个重大健康问题。虽然正在作出相当大的努力来了解和解决一般人口体力活动水平低的问题，但对残疾儿童的研究很少。我们认为，由于疾病的性质，患有DCD的儿童特别容易出现低活动量、低体能水平和肥胖。DCD是一种以运动协调性受损为特征的神经性发育障碍，严重干扰学习成绩和日常生活活动。由于协调性差，患有DCD的儿童往往无法与同龄人一起参加体育活动。这项研究的目标是检验我们的总体假设，即患有DCD的儿童活动较少，久坐不动，因此与运动协调能力良好的儿童相比，患肥胖症的风险更大，健康水平更低。我们将检验参与体力活动和久坐不动的行为与健康和体重状况之间的关联是否在患有DCD和具有足够运动协调性的儿童之间有所不同。我们将使用最先进的方法来测量活动水平(加速法)。我们将确定DCD儿童的总体活动量是否显著低于运动协调性一般的儿童，中等强度活动的时间较少，久坐行为的时间较长，身体健康水平明显较低，BMI z评分和肥胖风险显著较高(&gt；85%)。将审查措施之间的关系，以了解患有DCD的儿童的体力活动对体重状况和健康的影响是否与具有足够协调能力的儿童相同。该项目是对2010年健康人目标的响应，这些目标旨在增加全国青年的体育活动。患有DCD的儿童代表了人口中相当数量的儿童，由于他们的协调障碍，他们面临更高的风险。这项研究对其他有特殊需要的儿童有更广泛的影响，例如那些学习障碍和自闭症儿童，他们也被发现存在可能限制参与的协调缺陷。
