新兵基础训练期间应力性骨折危险因素的病例对照研究

A case-control study on risk factors of stress fractures in military re-cruits during basic training

应力性骨折（ＳＦ）是新兵基础训练中发生率较高、影响较大的一种训练伤．为了初步探讨其危险因素，为深入研究其病因提供线索，作者进行了病例对照研究，经单因素分析及多因素Ｌｏｇｉｓｔｉｃ回归模型拟合分析发现，训练中曾有病休、难以跟上行军速度、较小的胫骨长度与腿长比值是ＳＦ的危险因素；作者认为胫骨的相对长度（胫骨长／腿长）较绝对长度可能更能反映胫骨生物力学性能，带伤训练及疲劳状态下训练是有害的．

Stress fracture(SF)is a common training injury with high incidence during recruits basic training.A case-control study was undertaken to investigate the risk factors of SF.Results of single variable analysisand multivariate Logistic regression analysis revealed that injury,fatigue and a lower length ratio of tibia andpelvic limb were the main risk factors of SF.Authors are of the opinion that compared with the absolutelength of tibia,the relative length of tibia(tibia length/pelvic limb length)may be more relevant to tibiabiomec hanical characteris tics.The harm of tra ining under the conditions of injury or fatigue was also dis-cussed.
