High body mass index (BMI) and a previous running-related injury (RRI) have been highlighted as two risk factors for sustaining an RRI. However, a critical gap exists in the knowledge of whether runners with both elevated BMI and a previous RRI constitute a particularly vulnerable subgroup in terms of susceptibility to new RRIs. Therefore, the present study aimed to evaluate if those with high BMI and a concomitant history of running-related problems in the past 3 months were more prone to sustain a new RRI compared with runners with normal BMI and without previous running-related problems. This study was part of the "Garmin-RUNSAFE Running Health Study," an 18-month cohort study. The runners completed a baseline questionnaire containing questions regarding demographic data and previous running-related problems and were asked to continuously track their running activities. The exposure were dichotomized into "no previous running-related problem" or "previous running-related problem," and each group was further categorized into four subgroups depending on BMI. Time-to-event analysis was used to estimate the cumulative incidence risk difference (cIRD). The results highlight those with a BMI >30 kg/m with a previous running-related problem to face the highest injury risk of 71%, whereas those with a BMI between 19 and 25 kg/m without a previous running-related problem had the lowest injury risk of 43% corresponding to a cIRD of 28% [95% CI: 19%; 36%]. This result highlights those with high BMI and previous running-related problems as a high-risk subpopulation that would benefit from interventions of preventing running-related injuries.
高体重指数（BMI）和既往跑步相关损伤（RRI）已被视为发生RRI的两个风险因素。然而，对于BMI升高且既往有RRI的跑步者在发生新的RRI易感性方面是否构成一个特别脆弱的亚组，目前还存在关键的认知空白。因此，本研究旨在评估与BMI正常且既往无跑步相关问题的跑步者相比，BMI高且在过去3个月有跑步相关问题史的人是否更容易发生新的RRI。本研究是“佳明-跑步安全跑步健康研究”的一部分，这是一项为期18个月的队列研究。跑步者完成了一份基线问卷，其中包含有关人口统计学数据和既往跑步相关问题的问题，并被要求持续跟踪他们的跑步活动。暴露情况被分为“既往无跑步相关问题”或“既往有跑步相关问题”，每组再根据BMI进一步分为四个亚组。采用事件发生时间分析来估计累积发病率风险差异（cIRD）。结果显示，BMI>30kg/m且既往有跑步相关问题的人面临的最高损伤风险为71%，而BMI在19至25kg/m之间且既往无跑步相关问题的人损伤风险最低，为43%，对应的cIRD为28%[95%CI：19%；36%]。这一结果凸显了BMI高且既往有跑步相关问题的人是一个高风险亚人群，他们将受益于预防跑步相关损伤的干预措施。
