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找出导致患有发育性协调障碍（DCD）的儿童缺乏体育活动的因素，并制定干预措施以促进体育活动和降低健康风险。缺乏足够的体育活动是美国儿童的一个重大健康问题。虽然人们正在努力了解和解决普通人群身体活动水平低的问题，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DCD的儿童在低活动、低健康水平和肥胖方面的风险特别大。DCD是一种基于神经系统的发育障碍，其特征是运动协调能力受损，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。这项研究的目的是测试我们的首要假设，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，肥胖的风险更大，健康水平更低。我们将研究参与体育活动和久坐行为的时间与健康和体重状况的关系，在患有DCD的儿童和运动协调能力良好的儿童之间是否存在差异。我们将使用最先进的方法来测量活动水平（加速度计）。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总体活动量，花较少的时间进行中等强度的活动而花更多的时间进行久坐行为，身体健康水平明显较低，BMI z分数和肥胖风险患病率（bbb85 %）明显较高。将检查各项措施之间的关系，以了解DCD儿童的体育活动是否对体重状况和健康状况具有与协调能力良好的儿童相同的影响。这一项目响应了旨在增加全国青年体育活动的2010年健康人目标。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，他们的风险甚至更高。这项研究对其他有特殊需要的儿童有更广泛的影响，比如那些有学习障碍和自闭症的儿童，他们也被认为有协调缺陷，可能会限制他们的参与。
