A persistently low population level of physical activity is a challenge for public health. Data on cost effectiveness of environmental interventions are needed to inform the development and implementing of such interventions.
To conduct cost-effectiveness analysis of bicycle/pedestrian trails.
The costs of trail development and number of users of four trails in Lincoln, NE, were obtained. The costs were adjusted to 2003 dollars. The physical activity-related outcomes/items are number of users who were more physically active since they began using the trails, number of users who were physically active for general health, and number of users who were physically active for weight loss. Cost-effectiveness measures were derived. Sensitivity analysis was performed.
The annual trail development cost US$289,035, 73% of which was construction cost. Of the 3,986 trail users, 88% were active at least 3 days a week. The average annual cost for persons becoming more physically active was US$98 (range US$65-253); the cost was US$142 (range US$95-366) for persons who are active for general health, and US$884 (range US$590-2,287) for persons who are active for weight loss.
This analysis provides basic cost-effectiveness measures of bicycle/pedestrian trails. Policymakers can use this information in making resource allocation decisions.
人群身体活动水平持续偏低对公共卫生构成挑战。需要有关环境干预措施成本效益的数据，以为此类干预措施的制定和实施提供依据。
对自行车道/人行道进行成本效益分析。
获取了内布拉斯加州林肯市四条步道的建设成本和使用者数量。成本已按2003年美元进行调整。与身体活动相关的结果/项目包括：自开始使用步道以来身体活动增加的使用者数量、为总体健康而进行身体活动的使用者数量以及为减肥而进行身体活动的使用者数量。得出成本效益指标，并进行敏感性分析。
步道每年的建设成本为289,035美元，其中73%为建设费用。在3,986名步道使用者中，88%每周至少活动3天。身体活动增加者的平均年度成本为98美元（范围为65 - 253美元）；为总体健康而活动者的成本为142美元（范围为95 - 366美元），为减肥而活动者的成本为884美元（范围为590 - 2,287美元）。
本分析提供了自行车道/人行道的基本成本效益指标。政策制定者可利用这些信息做出资源分配决策。
