Cost effectiveness of a bicycle/pedestrian trail development in health promotion.

摘要

BACKGROUND: 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. OBJECTIVE: To conduct cost-effectiveness analysis of bicycle/pedestrian trails. DESIGN: 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. RESULTS: The annual trail development cost US
