Data on the problem of physical activity-related injury (PARI) in university students and the risk factors for PARI among different genders are rare. We conducted a multicentre population-based study to investigate the occurrence of PARI and to explore the gender-specific risk factors for PARI among Chinese university students.
Cross-sectional study.
A total of 5341 students in grades 1-3 at eight universities in four Chinese cities were selected to complete the online questionnaires during March and April 2017. The questionnaires assessed sociodemographic characteristics, physical activity PA) involvement, sleep duration, sedentary behaviour and PARI experiences in the past 12 months.
PARI during the past 12 months.
Among the 5341 participants, 1293 suffered from at least one PARI in the past 12 months, with an overall incidence rate of 24.2% (males: 26.2%, females: 23.2%) and an injury risk of 0.38 injuries/student/year (males: 0.48, females: 0.32). Over half of the injured (57.3%) experienced a withdrawal time of PA and nearly two-fifths (39.6%) required medical attention. Irrespective of gender, Shantou and Xi'an students, sports team members and those who engaged in sports and leisure-time vigorous-intensity PA (VPA) at a higher frequency were more likely to suffer from PARI. Male students who participated in sports and leisure-time VPA for long durations had a greater likelihood of sustaining PARI, while having a chronic condition and being involved in sports and leisure-time moderate-intensity PA at a higher frequency and longer duration were potential contributors to PARI among females.
The occurrence of PARI and its risk factors differed by gender, which provides a direction towards developing targeted and effective gender-specific preventative programmes to protect Chinese university students from PARI.
有关大学生与体力活动相关损伤（PARI）的问题的数据以及不同性别中 PARI 的风险因素较为少见。我们进行了一项多中心基于人群的研究，以调查中国大学生中 PARI 的发生情况，并探讨 PARI 的性别特异性风险因素。
横断面研究。
2017 年 3 月至 4 月期间，从中国四个城市的八所大学的 1-3 年级中选择了 5341 名学生完成在线问卷。问卷评估了社会人口统计学特征、体力活动（PA）参与情况、睡眠持续时间、久坐行为以及过去 12 个月中 PARI 的经历。
过去 12 个月中的 PARI。
在 5341 名参与者中，1293 名在过去 12 个月中至少遭受过一次 PARI，总体发生率为 24.2%（男性：26.2%，女性：23.2%），损伤风险为 0.38 次损伤/学生/年（男性：0.48，女性：0.32）。超过一半的受伤者（57.3%）停止了 PA，近五分之二（39.6%）需要医疗护理。无论性别如何，汕头和西安的学生、运动队成员以及那些更频繁地从事运动和休闲时间剧烈强度 PA（VPA）的人更有可能遭受 PARI。长时间进行运动和休闲时间剧烈强度 PA 的男性学生更有可能遭受 PARI，而患有慢性病以及更频繁和长时间进行运动和休闲时间中度强度 PA 的女性则是 PARI 的潜在原因。
PARI 的发生及其风险因素因性别而异，为制定有针对性和有效的性别特异性预防计划以保护中国大学生免受 PARI 提供了方向。
