Objective:To investigate the incidence of lumbar disc herniation (LDH) in soldiers at high altitude. Methods: An epidemiological survey was carried out among the soldiers at high altitude (2 200 - 4 000 m). LDH was identified by clinical and radiologic examinations, and was classified and analyzed according to type of the service (infantrymen and trucker soldiers) and age. Results; Among the 2 861 investigated soldiers (1 343 infantrymen and 1 518 trucker soldiers) , 27. 7 % were diagnosed as LDH. The incidence of trucker soldiers (30.76% ) was higher than that of the infantrymen (24. 20% ). The oldest group (age 3:26) had the highest incidence in both of the infantrymen and trucker soldiers groups. The LDH incidence of the infantrymen (18.64% ) in 17 -20 age group was higher than that of the trucker soldiers (11.60% ) , but was lower in 21 - 25 age group (27. 81% vs 38.95% ) and the oldest age group (36.67% vs 62. 58% ). Conclusion: The soldiers at high altitude have a higher incidence of LDH than those at plain. There is obvious differece in the incidence of LDH with different age between the infantrymen and trucker soldiers.%目的:调查高原地区部队官兵腰椎间盘突出症(lumbar disc herniation,LDH)患病情况.方法:问卷调查海拔2 200～4000 m地区驻军官兵2 861人,其中步兵1 343人,17～20岁558人,21～25岁755人,≥26岁30人.汽车兵1 518人,17～20岁595人,21 ～25岁760人,≥26岁163人.筛选出腰腿疼痛患者,通过临床检查确诊腰椎间盘突出症患者,按兵种和年龄段分类统计.结果:本资料确诊为腰椎间盘突出症患者792例,年龄17 ～48岁,平均24.2岁.整体发病率27.7％.步兵患病325例,患病率为24.20％.其中17 ～20岁104例,21 ～25岁210例,≥26岁11例,患病率分别为18.64％,27.81％,30.67％.汽车兵患病467例,患病率为30.76％.其中17～ 20岁69例,21～ 25岁296例,≥26岁102例,患病率分别为11.60％,38.95％,62.58％.结论:受高原环境因素影响,高原地区部队官兵腰椎间盘突出症的发病率较高,发病年龄偏低,不同兵种、不同年龄段发病率不一,预防发病应采取相应的措施.
