We investigated the prevalence and distribution of Musculoskeletal Disorders (MSD) among Chinese medical students, by means of a questionnaire survey. A total of 207 questionnaires were successfully returned, giving a high response rate of 92.4%. The MSD period-prevalence at any body site was 67.6% in the previous year and 46.9% in the previous week. Almost one-third of them (31.9%), reported an ongoing MSD. By individual body site, the most commonly affected region was the lower back (40.1% in the last year), followed by the neck (33.8%) and shoulders (21.7%). The 7 day period-prevalence also followed a similar descending pattern, being reported by 20.8% at the lower back and 12.1% at both the neck and knees. MSD affected the daily life of students for an average period of 53.8 days, with an average of 6.6 sick days taken from school. Students reporting high mental pressure were 2.9 times more likely to suffer low back pain in the previous 12 months (OR 2.9, 95%CI 1.4-5.9, P=0.0030). Overall, our study suggests that Chinese medical students are at reasonable MSD risk, although it is probably lower than for working physicians. Further investigations are now recommended to elucidate the MSD mechanisms and contributory factors among medical students in China, as elsewhere. A longitudinal study of MSD among a complete group of medical students would be very useful in this regard.
我们通过问卷调查的方式，对中国医学生肌肉骨骼疾病（MSD）的患病率及分布情况展开了调查。总共成功回收了207份问卷，回应率高达92.4%。MSD在任何身体部位的过去一年期间患病率为67.6%，过去一周为46.9%。其中近三分之一（31.9%）报告称患有持续性MSD。按身体部位来看，最常受影响的区域是下背部（去年为40.1%），其次是颈部（33.8%）和肩部（21.7%）。7天期间患病率也呈现类似的下降模式，下背部报告患病率为20.8%，颈部和膝盖均为12.1%。MSD影响学生日常生活的平均时长为53.8天，平均请假6.6天。报告称精神压力大的学生在过去12个月患下背痛的可能性是其他学生的2.9倍（比值比2.9，95%置信区间1.4 - 5.9，P = 0.0030）。总体而言，我们的研究表明，中国医学生面临的MSD风险处于合理水平，尽管可能低于在职医生。建议进一步开展调查，以阐明中国医学生以及其他地区医学生中MSD的发病机制和促成因素。在这方面，对全体医学生进行MSD纵向研究将非常有用。
