To investigate whether the proportion of running-related knee injuries differed in normal-weight, overweight, and obese runners.
Comparative study.
Data from 4 independent prospective studies were merged (2612 participants). The proportion of running-related knee injuries out of the total number of running-related injuries was calculated for normal-weight, overweight, and obese runners, respectively. The measure of association was absolute difference in proportion of running-related knee injuries with normal-weight runners as the reference group.
A total of 571 runners sustained a running-related injury (181 running-related knee injuries and 390 running-related injuries in other anatomical locations). The proportion of running-related knee injuries was 13% lower (95% confidence interval: -22%, -5%; = .001) among overweight runners compared with normal-weight runners. Similarly, the proportion of running-related knee injuries was 12% lower (95% confidence interval: -23%, -1%; = .042) among obese runners compared with normal-weight runners.
Overweight and obese runners had a lower proportion of running-related knee injuries than normal-weight runners. .
探讨正常体重、超重和肥胖跑者的跑步相关膝关节损伤比例是否存在差异。
比较研究。
合并了 4 项独立的前瞻性研究的数据（2612 名参与者）。分别计算了正常体重、超重和肥胖跑者中跑步相关膝关节损伤占跑步相关损伤总数的比例。以正常体重跑者为参照组，以跑步相关膝关节损伤的比例差异为关联指标。
共有 571 名跑者发生了跑步相关损伤（181 例跑步相关膝关节损伤和 390 例其他解剖部位的跑步相关损伤）。与正常体重跑者相比，超重跑者的跑步相关膝关节损伤比例低 13%（95%置信区间：-22%，-5%； =.001）。同样，与正常体重跑者相比，肥胖跑者的跑步相关膝关节损伤比例低 12%（95%置信区间：-23%，-1%； =.042）。
与正常体重跑者相比，超重和肥胖跑者的跑步相关膝关节损伤比例较低。
