The purpose of this study was to estimate surface-specific rates of fall injuries on school playgrounds. Playground injuries related to falls from climbing equipment and the surfaces involved were identified from injury reports for 1988 to 1990 from 157 Utah elementary schools. Enrollment data and playground inspections were used to estimate student-years spent over each surface. The fall injury rates per 10,000 student-years were asphalt, 44; grass, 12; mats, 16; gravel, 15; and sand, 7. These data did not show that impact-absorbing surfaces reduce fall injuries on playgrounds better than grass. Improved field studies are needed to guide policy decisions for playground surfacing.
本研究的目的是估算学校操场表面特定的跌倒受伤率。从犹他州157所小学1988年至1990年的伤害报告中，识别出与从攀爬设备跌落及相关表面有关的操场伤害。利用入学数据和操场检查来估算学生在每个表面上度过的学生年数。每10000学生年的跌倒受伤率分别为：沥青地面44起；草地12起；垫子16起；砾石15起；沙地7起。这些数据并未表明，与草地相比，具有冲击吸收功能的表面能更好地减少操场跌倒受伤情况。需要开展更完善的实地研究，以指导操场地面铺设的政策决策。
