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因发育协调障碍（DCD）儿童体育锻炼不足的因素，并制定干预措施以促进体育锻炼并降低健康风险。缺乏足够的体育活动是美国儿童的重大健康问题。尽管正在努力理解和解决一般人群中身体活动水平较低的问题，但在残疾儿童中的研究很少。我们建议患有DCD的儿童由于疾病的性质而有少量活动，健身水平和肥胖水平较低的风险。 DCD是一种基于神经系统的发育障碍，其特征是运动协调受损，它极大地干扰了学业成就和日常生活活动。由于协调不佳，DCD的儿童通常无法与同龄人一起参加运动和体育活动。这项研究的目标是检验我们的总体假设，即DCD的儿童比具有足够运动协调的儿童的肥胖症和健身水平更大，因此肥胖和健身水平较低。我们将检查参与体育锻炼和久坐行为花费的时间是否与健身和体重状况之间的时间之间的关系是否有所不同，并且在患有足够的运动协调性的儿童之间是否有所不同。我们将使用最先进的方法来测量活动水平（加速度计）。我们将确定患有DCD的儿童是否表现出明显降低的整体活动，在中度剧烈的活动中花费更少的时间，以及久坐不动的时间，比平均运动配位的儿童的身体健康水平明显降低，BMI Z得分的水平明显较低，BMI Z得分和肥胖风险的患病率明显更高（> 85％）。将检查措施之间的关系，以了解DCD儿童的体育活动对体重状况和适应性是否与适当协调的儿童相同。该项目对2010年健康人的目标有回应，该目标试图增加国家青年的体育锻炼。 DCD的儿童代表着大量人口中的儿童，由于其协调障碍，他们的风险更高。该研究对其他有特殊需要的儿童（例如学习障碍和自闭症的孩子）具有更广泛的影响，他们也被确定为可能限制参与的协调缺陷。
