Several studies have indicated that slip-resistant shoes may have a positive effect on reducing the risk of slips and falls, a leading cause of injury at work. Few studies, however, have examined how duration of shoe usage affects their slip-resistance properties. This study examined the association between the duration of slip-resistant shoes usage and the self-reported rate of slipping in limited-service restaurant workers. A total of 475 workers from 36 limited-service restaurants in the USA were recruited to participate in a 12-week prospective study of workplace slipping. Of the 475 participants, 83 reported changing to a new pair of shoes at least once during the 12-week follow-up. The results show that slip-resistant shoes worn for less than six months were moderately more effective than those worn for more than six months. Changing to a new pair of shoes among those wearing slip-resistant shoes at baseline was associated with a 55% reduction in the rate of slipping (RR = 0.45, 95% CI = 0.23-0.89). Further research is needed to develop criteria for the replacement of slip-resistant shoes.
多项研究表明，防滑鞋可能对降低滑倒和跌倒风险具有积极作用，而滑倒和跌倒是工作场所受伤的主要原因。然而，很少有研究探讨鞋子的使用时长如何影响其防滑性能。本研究调查了防滑鞋的使用时长与有限服务餐厅员工自我报告的滑倒率之间的关联。在美国，从36家有限服务餐厅共招募了475名员工，参与一项为期12周的工作场所滑倒前瞻性研究。在475名参与者中，有83人报告在12周的随访期间至少更换过一次新鞋。结果显示，穿着不足六个月的防滑鞋比穿着超过六个月的防滑鞋在防滑效果上略胜一筹。在基线时穿着防滑鞋的人群中，更换新鞋与滑倒率降低55%相关（相对危险度=0.45，95%置信区间=0.23-0.89）。需要进一步开展研究以制定更换防滑鞋的标准。
