Many school-based recess interventions have been shown to be effective in increasing physical activity but their relative efficiency compared to other school-based programs are unknown. This study examined the cost-effectiveness of Ready for Recess, a program designed to increase students' physical activity in 2 elementary schools.
Standard cost-effectiveness analysis method was used from a program's perspective for this study. Program effectiveness was measured as total metabolic equivalent (MET) hours gained. Program costs included equipment, training, and personnel costs during the 1-year intervention. The cost-effectiveness was measured as the ratio of program costs to total MET-hours gained.
Ready for Recess cost $27,643.97 for the 2 schools in the first year of implementation. Physical activity increased by 1.8 MET-hours per day per student. Approximately 32 cents were spent on Ready for Recess to produce an additional MET-hour per student per school day in the 2008-2009 school year.
Ready for Recess was cost-effective in its first year of implementation using 35 cents as a benchmark and it was cost-effective relative to other school-based physical activity interventions. The program may be more cost-effective if implemented for a longer time and on a larger scale.
许多基于学校的课间休息干预措施已被证明能有效增加身体活动，但与其他基于学校的项目相比，其相对效率尚不清楚。本研究考察了“准备好课间休息”项目的成本效益，该项目旨在增加两所小学学生的身体活动。
本研究从项目角度采用标准成本效益分析方法。项目效果以获得的总代谢当量（MET）小时数来衡量。项目成本包括1年干预期间的设备、培训和人员成本。成本效益以项目成本与获得的总MET小时数的比率来衡量。
在实施的第一年，两所学校的“准备好课间休息”项目花费27,643.97美元。学生的身体活动量增加到每天每人1.8个MET小时。在2008 - 2009学年，为两所学校的每个学生每天额外产生1个MET小时的“准备好课间休息”项目花费约32美分。
以35美分为基准，“准备好课间休息”项目在实施的第一年具有成本效益，并且相对于其他基于学校的身体活动干预措施而言也是具有成本效益的。如果实施更长时间并扩大规模，该项目可能会更具成本效益。
