Compared to other children, those with disability have additional challenges to being physically active. Prader-Willi Syndrome is a genetic form of childhood obesity that is characterized by hypotonia, growth hormone deficiency, behavioral, and cognitive disability. In children, the low prevalence of this syndrome (1 in 10,000 to 15,000 live births) makes group-based physical activity interventions difficult. In contrast, the home environment presents a natural venue to establish a physical activity routine for this population. This manuscript describes the design of a parent-led physical activity intervention incorporating playground and interactive console-based games to increase physical activity participation in youth with and without Prader-Willi Syndrome.
METHODS/DESIGN: The study participants will be 115 youth ages 8-15 y (45 with the syndrome and 70 without the syndrome but categorized as obese). The study will use a parallel design with the control group receiving the intervention after serving as control. Participants will be expected to complete a physical activity curriculum 4 days a week for 6 months including playground games 2 days a week and interactive console games 2 days a week. Parents will be trained at baseline and then provided with a curriculum and equipment to guide their implementation of the program. Tips related to scheduling and coping with barriers to daily program implementation will be provided. Throughout, parents will be contacted by phone once a week (weeks 1-4) and then every other week to receive support in between visits. Measurements of children and parents will be obtained at baseline, 12 weeks, and at the end (week 24) of the intervention. Children main outcomes include physical activity (accelerometry), body composition (dual x-ray absorptiometry), motor proficiency (Bruininks-Oseretsky Test of Motor Proficiency), quality of life and physical activity self-efficacy (questionnaires). Intervention compliance will be monitored using mail-in daily self-report checklists.
This parent-guided physical activity intervention aims to increase physical activity by using a curriculum that builds physical activity related self-confidence through the development and/or enhancement of motor skill competency. Ultimately, helping children develop these skills as well as joy in being physically active will translate into sustained behavior change.

与其他儿童相比，残疾儿童在进行身体活动方面面临更多挑战。普拉德-威利综合征是一种儿童肥胖的遗传性疾病，其特征为肌张力低下、生长激素缺乏、行为和认知障碍。在儿童中，这种综合征的患病率较低（每 10000 至 15000 例活产中 1 例），因此基于群体的身体活动干预较为困难。相比之下，家庭环境为这一人群建立身体活动常规提供了自然场所。本文描述了一项以家长为主导的身体活动干预措施的设计，该措施结合了游乐场和互动控制台游戏，以增加患有和不患有普拉德-威利综合征的青少年的身体活动参与度。
方法/设计：研究参与者将包括 115 名 8-15 岁的青少年（45 名患有该综合征，70 名患有肥胖症但未患该综合征）。该研究将采用平行设计，对照组在作为对照组后接受干预。参与者预计将在 6 个月内每周完成 4 天的身体活动课程，其中包括每周 2 天的游乐场游戏和每周 2 天的互动控制台游戏。家长将在基线时接受培训，然后提供课程和设备，以指导他们实施该计划。将提供与日程安排相关的提示，并解决日常计划实施过程中的障碍。在此期间，家长将每周通过电话联系一次（第 1-4 周），然后在访问之间每两周联系一次以获得支持。在干预开始时（第 0 周）、第 12 周和第 24 周（干预结束时）将对儿童和家长进行测量。儿童的主要结果包括身体活动（加速度计）、身体成分（双能 X 线吸收法）、运动能力（布鲁因克斯-奥塞尔斯基运动能力测试）、生活质量和身体活动自我效能感（问卷）。干预依从性将通过邮寄每日自我报告检查表进行监测。
这项由家长指导的身体活动干预旨在通过使用课程来增加身体活动量，该课程通过发展和/或增强运动技能能力来建立与身体活动相关的自信心。最终，帮助儿童发展这些技能以及对身体活动的乐趣将转化为持续的行为改变。
