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（由申请人提供）：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并降低健康风险。缺乏足够的身体活动是美国儿童的一个重大健康问题。尽管人们正在努力了解和解决普通人群体力活动水平低的问题，但对残疾儿童的研究却很少。我们认为，由于疾病的性质，患有发展性协调障碍 (DCD) 的儿童特别容易出现活动量少、健康水平低和肥胖的风险。 DCD 是一种神经发育障碍，其特征是运动协调受损，严重干扰学业成绩和日常生活活动。由于协调性差，患有发展性协调障碍的儿童常常无法与同龄人一起参加体育运动和体育活动。本研究的目的是检验我们的总体假设，即患有 DCD 的儿童活动较少、久坐较多，因此与运动协调能力良好的儿童相比，肥胖风险更大且健康水平较低。我们将研究患有发展性协调障碍 (DCD) 和具有足够运动协调能力的儿童之间参与体力活动和久坐行为所花费的时间与健康和体重状况之间的关联是否有所不同。我们将使用最先进的方法来测量活动水平（加速度测量）。我们将确定与运动协调能力一般的儿童相比，患有 DCD 的儿童是否表现出明显较低的整体活动、花在中等强度活动上的时间较少、久坐行为的时间较多、体能水平是否显着较低、BMI z 分数和肥胖风险患病率是否显着较高（>85%）。将检查测量之间的关系，以了解患有发展性协调障碍 (DCD) 的儿童的体力活动是否对体重状况和健康具有与具有足够协调能力的儿童相同的影响。该项目响应“2010 年健康人民”目标，旨在增加全国年轻人的身体活动。患有发展性协调障碍 (DCD) 的儿童在人口中占很大一部分，由于他们的协调障碍，他们面临的风险甚至更高。这项研究对其他有特殊需要的儿童具有更广泛的影响，例如那些有学习障碍和自闭症的儿童，这些儿童也被认为存在可能限制参与的协调缺陷。
