DESCRIPTION (provided by applicant): The overall aim of this project is to determine the efficacy of Steps to Your Health (STYH), a health promotion program, in adults with mental retardation, autism, or traumatic brain injury. STYH is an eight session participatory and didactic intervention that has been utilized for over ten years in these population groups in South Carolina. It emphasizes physical activity, good nutrition, and stress reduction as key aspects of a healthy lifestyle. Ongoing program evaluations indicate that STYH participants significantly improve in their knowledge, physical activity, and diet in addition to losing weight. Previous evaluations, while promising do not provide definitive proof of a program impact, as they did not utilize experimental study designs. Given the need for demonstrably effective health promotion interventions for persons with cognitive disabilities, the promising evaluation results call for a well-controlled study of program efficacy. The proposed study is a randomized trial of the STYH program community-dwelling adults in South Carolina with mild to moderate cognitive impairment due to mental retardation, autism, or traumatic brain injury. Participants will be recruited through local disability service agencies and randomized to participate in the STYH program or serve as controls. While randomization will be at the individual level, all adults living in the same household with an intervention participant will be encouraged to participate in the program as well, though they will not be included in the analyses. Participants and controls will be assessed at baseline and one week, six months, and twelve months following program completion. The key study outcomes are levels of physical activity as measured by self report and accelerometers, dietary composition as measured by self report and direct observation, and weight loss. Knowledge about diet, exercise, and stress reduction will also be assessed. We hypothesize that STYH participants will exhibit increased physical activity, healthier diets, and greater weight loss in comparison with controls. We further hypothesize, based on previous analyses that increased knowledge will be the primary intermediate variable that accounts for the program impact in each of these areas. This research will provide important information on an existing health promotion program for adults with cognitive disabilities and will inform future efforts at designing effective interventions for this population.

描述（由申请人提供）：该项目的总体目标是确定健康促进计划 (STYH) 对患有精神发育迟滞、自闭症或创伤性脑损伤的成年人的功效。 STYH 是一项八次参与式和说教性干预措施，已在南卡罗来纳州的这些人群中使用了十多年。它强调身体活动、良好的营养和减轻压力作为健康生活方式的关键方面。正在进行的项目评估表明，除了减肥之外，STYH 参与者在知识、身体活动和饮食方面也有显着提高。之前的评估虽然很有希望，但并没有提供项目影响的明确证据，因为它们没有利用实验研究设计。鉴于需要对认知障碍者采取明显有效的健康促进干预措施，有希望的评估结果需要对项目效果进行严格控制的研究。拟议的研究是对南卡罗来纳州 STYH 计划社区居住的成年人进行的一项随机试验，这些成年人因智力低下、自闭症或创伤性脑损伤而患有轻度至中度认知障碍。参与者将通过当地残疾服务机构招募并随机参加 STYH 计划或作为对照。虽然随机化将在个人层面进行，但也将鼓励与干预参与者生活在同一家庭的所有成年人参与该计划，尽管他们不会被纳入分析。将在基线以及计划完成后一周、六个月和十二个月对参与者和对照进行评估。主要研究结果是通过自我报告和加速度计测量的身体活动水平、通过自我报告和直接观察测量的饮食成分以及体重减轻。还将评估有关饮食、运动和减压的知识。我们假设，与对照组相比，STYH 参与者将表现出更多的体力活动、更健康的饮食和更大的体重减轻。根据之前的分析，我们进一步假设增加的知识将是解释每个领域的计划影响的主要中间变量。这项研究将为患有认知障碍的成年人提供有关现有健康促进计划的重要信息，并将为未来为该人群设计有效干预措施的努力提供信息。
