Increase in physical activity (PA) might elevate risks for physical-activity-related injuries (PARIs). This study aimed to investigate the incidence rate and risk factors for PARIs among secondary school students in Hong Kong. All eligible students from three secondary schools were invited to participate in the study from November to December 2014. Information on PARI occurrences in the past 12 months, PA participation, and sociodemographics was collected. Multivariate and hierarchical logistic regression models were performed to estimate the risk of potential factors for PARIs. In total, 1916 students in forms 1-6 (aged 14.3 ± 1.7 years) completed valid questionnaires, with an overall yearly PARI incidence rate of 32.1% (boys: 34.3%; girls: 29.3%). There were sex differences in the risk factors identified, except that family size was associated with PARIs for all participants. Longer duration and higher intensity of PA increased the risk for PARI occurrences in both sexes. In conclusion, PARIs were prevalent among secondary school students in Hong Kong, and different sexes had different PARI incidence rates and were influenced by different risk factors. There is an urgent call for effective sex-specific interventions to prevent PARIs in this population.
体力活动（PA）的增加可能会增加与体力活动相关的伤害（PARIs）的风险。本研究旨在调查香港中学生 PARIs 的发生率和危险因素。2014 年 11 月至 12 月，邀请了三所中学的所有符合条件的学生参加这项研究。收集了过去 12 个月中发生 PARIs 的信息、PA 参与情况和社会人口统计学信息。采用多变量和分层逻辑回归模型来估计 PARIs 的潜在因素的风险。共有 1916 名 1 至 6 年级的学生（年龄 14.3±1.7 岁）完成了有效问卷，总体年 PARIs 发生率为 32.1%（男生：34.3%；女生：29.3%）。除了家庭规模与所有参与者的 PARIs 相关外，确定的危险因素在性别方面存在差异。PA 的持续时间和强度增加都会增加男女发生 PARIs 的风险。总之，PARIs 在香港中学生中很普遍，不同性别发生 PARIs 的发生率不同，受不同的危险因素影响。迫切需要针对这一人群采取有效的性别特异性干预措施来预防 PARIs。
