项目摘要

The benefits of physical activity for adults are well established, but less than one-third of older adults in the U.S. have achieved recommended levels of physical activity despite widespread clinical recommendations to increase physical activity in recent years. Clinic-based approaches to increasing physical activity are expensive, difficult to implement in busy practice settings, and have limited reach. Moreover, evidence of the efficacy of such approaches is equivocal. A population based approach may be a more effective and less costly strategy to increase levels of physical activity in older adults. Population studies of physical activity have demonstrated that each year, many sedentary older adults initiate physical activity, but a nearly equal number of those who were active become sedentary. Among older adults initiating physical activity, only half continue to be active 3 months later. We hypothesize that a population based approach that emphasizes physical activity maintenance can substantially increase physical activity levels in a defined populations of older adults. This hypothesis is tested in a 24-month randomized trial evaluating an innovative, theory-based behavioral intervention to maintain physical activity in a random sample of 50-70 year old adults who have recently become at least moderately active. One thousand (1000) subjects will be randomized to one of two experimental groups: 1) a "usual care" control group, and 2) an interactive phone- and mail-based intervention program tailored to maintaining physical activity in older adults. The primary outcome measures are: 1) physical activity, assessed as kcals/wk expenditure; and 2) physical activity maintenance, assessed as follow-up kcals/wk expenditure relative to baseline. Careful measurement of the penetration of the intervention into a well characterized older adult population, and the costs of the intervention, will be assessed. Psychosocial and behavioral mediators of physical activity maintenance will also be examined. Study results will be relevant to policy makers, health promotion practitioners and health plans, and will provide practical information on the effectiveness, population penetration, and costs of an intervention designed to maximize population levels of physical activity amon 9 older adults.

体育锻炼对成年人的好处已建立得很好，但不到三分之一的老年人尽管广泛的临床建议，美国已经达到了建议的体育活动近年来增加体育活动。基于诊所的增加体育锻炼的方法是在繁忙的练习环境中昂贵，难以实施，并且覆盖范围有限。而且，证据这种方法的功效是模棱两可的。基于人群的方法可能更有效，并且成本较小的策略，以增加老年人体育锻炼水平。人口研究活动表明，每年，许多久坐的老年人都会发起体育锻炼，但几乎相等的活跃人数久坐的人。在老年人中发起身体活动，只有一半继续活跃3个月后。我们假设强调体育活动维护的基于人群的方法可以在定义的老年人中，大大提高了体育活动水平。这个假设是在一项24个月的随机试验中测试，评估了创新的，基于理论的行为干预措施在50-70岁的成年人的随机样本中保持体育活动中度活动。一千（1000）受试者将被随机分为两个实验组之一：1）一个“通常的护理”对照组，2）量身定制的基于电话和邮件的干预计划维持老年人的体育锻炼。主要结果指标是：1）体育锻炼，评估为KCALS/WK支出； 2）维持体育锻炼，评估为随访KCALS/WK 相对于基线的支出。仔细测量干预措施中的渗透将评估以老年人的特征和干预成本进行评估。社会心理和还将检查体育活动维护的行为介体。研究结果将与政策制定者，健康促进从业人员和健康计划有关，并将提供有关有效性，人口渗透和干预成本的实用信息旨在最大程度地提高体育锻炼的水平，为9名老年人。
