Financial incentives have been advocated by the UK and U.S. governments to encourage adoption of healthy lifestyles. However, evidence to support the use of incentives for changing physical activity (PA) behavior is sparse.
To investigate the effectiveness of financial incentives to increase PA in adults in the workplace.
Two-arm quasi-experimental design.
SETTING/PARTICIPANTS: Employees (n=406) in a workplace setting in Belfast, Northern Ireland, UK.
Using a loyalty card to collect points and earn rewards, participants (n=199) in the Incentive Group monitored their PA levels and received financial incentives (retail vouchers) for minutes of PA completed over the course of a 12-week intervention period. Participants (n=207) in the comparison group used their loyalty card to self-monitor their PA levels but were not able to earn points or obtain incentives (No Incentive Group).
The primary outcome was minutes of PA objectively measured using a novel PA tracking system at baseline (April 2011); Week 6 (June 2011); and Week 12 (July 2011). Other outcomes, including a self-report measure of PA, were collected at baseline, Week 12, and 6 months (October 2011). Data were analyzed in June 2012.
No significant differences between groups were found for primary or secondary outcomes at the 12-week and 6-month assessments. Participants in the Incentive Group recorded 17.52 minutes of PA/week (95% CI=12.49, 22.56) compared to 16.63 minutes/week (95% CI=11.76, 21.51) in the No Incentive Group at Week 12 (p=0.59). At 6 months, participants in the Incentive Group recorded 26.18 minutes of PA/week (95% CI=20.06, 32.29) compared to 24.00 minutes/week (95% CI=17.45, 30.54) in the No Incentive Group (p=0.45).
Financial incentives did not encourage participants to undertake more PA than self-monitoring PA. This study contributes to the evidence base and has important implications for increasing participation in physical activity and fostering links with the business sector.
英国和美国政府提倡经济激励措施，以鼓励人们养成健康的生活方式。然而，目前支持使用激励措施来改变身体活动（PA）行为的证据还很有限。
调查经济激励措施对增加工作场所成年人 PA 的有效性。
双臂准实验设计。
地点/参与者：北爱尔兰贝尔法斯特工作场所的员工（n=406）。
使用会员卡收集积分并赚取奖励，激励组（n=199）参与者监测他们的 PA 水平，并在 12 周干预期间完成的 PA 分钟数获得经济奖励（零售券）。比较组（n=207）的参与者使用会员卡自我监测 PA 水平，但无法获得积分或奖励（无激励组）。
主要结果是使用新型 PA 跟踪系统在基线（2011 年 4 月）、第 6 周（2011 年 6 月）和第 12 周（2011 年 7 月）进行客观测量的 PA 分钟数。其他结果，包括 PA 的自我报告测量，在基线、第 12 周和 6 个月（2011 年 10 月）收集。数据分析于 2012 年 6 月进行。
在 12 周和 6 个月评估时，激励组和对照组在主要或次要结果方面没有发现显著差异。激励组参与者记录的 PA 每周 17.52 分钟（95%CI=12.49，22.56），而对照组每周 16.63 分钟（95%CI=11.76，21.51）（p=0.59）。6 个月时，激励组参与者每周记录的 PA 为 26.18 分钟（95%CI=20.06，32.29），而对照组为每周 24.00 分钟（95%CI=17.45，30.54）（p=0.45）。
经济激励措施并没有促使参与者比自我监测 PA 进行更多的 PA。本研究为增加身体活动的参与度和促进与企业部门的联系提供了证据基础，并具有重要意义。
