目标。只有不到一半的美国成年人符合公共卫生建议的体育活动，更少的老年人(50岁及以上)足够活跃。由于缺乏运动会增加昂贵的医疗并发症的风险，成功地增加老年人的体力活动可能是具有成本效益的。我们试图测试经济刺激步行是否可以增加久坐不动的老年人的体力活动。我们使用计步器进行了为期4周的随机对照研究。2007年4月至5月，来自北卡罗来纳州罗利-达勒姆地区的51名50岁以上的成年人参与了这项研究。受试者被随机分成两组。对照组获得了75美元的固定报酬；干预组获得了50美元的固定报酬，外加每周高达25美元的额外报酬，这取决于每周的有氧分钟数，即连续步行或慢跑10分钟以上。对照组平均每周工作2.3小时。干预组每周工作4.1h，平均每周额外获得17.50美元的报酬。与有氧分钟相关的适度经济激励是一种有效的、可能具有成本效益的方法，可以增加久坐的老年人的体力活动。(C)2008 Elsevier Inc.保留所有权利。
Objective. Less than half of all U.S. adults meet public health recommendations for physical activity, and even fewer older adults (aged 50 years and over) are sufficiently active. Because inactivity increases the risk of costly medical complications, successful efforts to increase physical activity among older adults may potentially be cost-effective. We sought to test if financial incentives for walking could increase physical activity among sedentary older adults.Methods. We conducted a 4-week randomized controlled study using pedometers. A total of 51 adults age 50+ from the Raleigh-Durham area of North Carolina participated in the study in April-May 2007. Individuals were randomized into one of two arms. The control group received a fixed payment of $75; the intervention group received a fixed payment of $50 plus up to $25 more per week depending on the number of weekly aerobic minutes, defined as 10+ minutes of continuous walking or jogging.Results. The control group logged 2.3 h per week, on average. The intervention group logged 4.1 h per week and received an additional weekly payment of $17.50, on average.Conclusion. Modest financial incentives tied to aerobic minutes are an effective, and potentially cost-effective, approach for increasing physical activity among sedentary older adults. (C) 2008 Elsevier Inc.
