简介：尽管有证据表明定期体育活动有益于健康，但老年人的体育活动率仍然很低。个人和社会目标都可以增强老年人变得活跃的动力。这项研究测试了经济激励、慈善捐款的效果，以及两种干预措施对老年人接受和保持步行水平提高的综合影响。研究设计：随机对照试验比较三种干预措施和对照。数据收集发生于 2012 年至 2013 年。分析于 2013 年至 2016 年进行。参与者：来自费城地区退休社区的 94 名年龄 >= 65 岁的成年人。干预：所有参与者都收到数字计步器、每日步数增加 50% 的步行目标以及每周目标实现情况反馈。参与者被随机分为四组之一：（1）对照组：仅每周收到反馈； (2) 经济激励：达到步行目标，每周获得 20 美元的报酬； (3) 社会目标：达到步行目标后，每周都会向选定的慈善机构捐赠 20 美元； (4) 综合：每周收到 20 美元的步行目标，参与者可以收到、捐赠给所选的慈善机构或在参与者和慈善机构之间分配。主要结果指标：在 16 周干预期间和 4 周随访期间达到步行目标的平均天数比例。结果：调整基线步行后，所有干预组在 16 周干预期间达到步数目标的天数比例均高于对照组（相对风险，3.71； 95% CI = 1.37, 10.01）。在 4 周的随访期间，与对照组相比，干预组中实现步数目标的天数比例没有差异（相对风险，2.91；95% CI = 0.62，13.64）。结论：使用向所选慈善机构捐款、个人经济激励或两者相结合的激励计划都可以提高老年人对增加步行水平的初始接受程度。 (C) 2016 年美国预防医学杂志。由爱思唯尔公司出版。保留所有权利。
Introduction: Despite evidence that regular physical activity confers health benefits, physical activity rates among older adults remain low. Both personal and social goals may enhance older adults' motivation to become active. This study tested the effects of financial incentives, donations to charity, and the combined effects of both interventions on older adults' uptake and retention of increased levels of walking.Study design: RCT comparing three interventions to control. Data collection occurred from 2012 to 2013. Analyses were conducted in 2013-2016.Participants: Ninety-four adults aged >= 65 years from Philadelphia-area retirement communities.Intervention: All participants received digital pedometers, walking goals of a 50% increase in daily steps, and weekly feedback on goal attainment. Participants were randomized to one of four groups: (1) Control: received weekly feedback only; (2) Financial Incentives: received payment of $20 each week walking goals were met; (3) Social Goals: received donation of $20 to a charity of choice each week walking goals were met; and (4) Combined: received $20 each week walking goals were met that could be received by participant, donated to a charity of choice, or divided between the participant and charity.Main outcome measures: Mean proportion of days walking goals were met during the 16-week intervention and 4-week follow-up period.Results: After adjusting for baseline walking, the proportion of days step goals were met during the 16-week intervention period was higher in all intervention groups versus controls (relative risk, 3.71; 95% CI = 1.37, 10.01). During the 4-week follow up period, the proportion of days step goals were met did not differ in intervention groups compared to control (relative risk, 2.91; 95% CI = 0.62, 13.64).Conclusions: Incentive schemes that use donations to a charity of choice, personal financial incentives, or a combination of the two can each increase older adults' initial uptake of increased levels of walking.
