中国某部队战士下腰痛流行病学调查

目的：通过问卷调查方式，了解某部队战士下腰痛的流行病学特点，阐明军事训练中引起下腰痛的相关危险因素。 方法：本文调查了1659名战士，收回有效问卷1624份。问卷分为2部分内容：（1）一般情况，包括年龄、体重指数、民族、吸烟与否、教育程度及婚姻状况。兵种分为装甲兵、炮兵、步兵。（2）军事训练中下腰痛危险因素分析：包括最近1周内每天队列训练时间、射击训练时间、投弹训练次数、400m障碍训练次数、装甲车内训练时间、炮兵专业训练时间、每周5公里越野次数、每周夜训次数等。对调查结果进行统计学分析。 结果：战士中下腰痛发病率为26.2% （425/1624)。其中装甲兵下腰痛发病率最高，为51.3%；炮兵次之，为27.5%；步兵最低，为11.9%。 多因素回归分析显示军事训练中每周夜训次数、每周5公里越野次数和每天投弹训练次数与下腰痛的发生有显著相关性。 结论：本研究发现战士中下腰痛发病率较高，尤其是装甲兵，揭示了引起下腰痛的相关危险因素。从而为今后有针对性的改进战士训练方法，改良训练设施，进而减少战士下腰痛的发生提供了理论依据。

The prevalence of low back pain among soldiers at a army base

Background Low back pain (LBP) is a major medical and social problem among working populations associated with high medical expense, lost productivity, and disability. The aim of this study is to investigate the prevalence of LBP among soldiers and evaluate the possible causative factors in military training. The results may provide insight into changes in military training that will reduce the occurrence of LBP among soldiers. Methods A cross-sectional survey was conducted in a group of young soldiers in China to estimate the prevalence of LBP and evaluate possible causative factors in military training. Results The survey was distributed to 1659 soldiers, of whom 1624 responded. LBP was reported by 425 of the 1624 (26.2%) soldiers. The prevalence of LBP was higher in the armored force (51.3%) than in the artillery (27.5%) or infantry (11.9%). A multivariate logical regression analysis identified night training, 5km cross-country race and grenade-throwing training as military training risk factors for LBP. Conclusions The relatively high incidence of LBP among soldiers was related to night training, 5km racing and grenade throwing. Modifications in these training methods should enhance the health of recruits and lower the incidence of LBP.
