目的 分析飞行人员慢性下腰痛的临床特征,为实施健康干预措施提供依据. 方法 收集在空军杭州航空医学鉴定训练中心疗养的飞行人员体检资料,提取年龄、飞行机种、身高、体重、肺活量等信息,出现下腰痛的为病例组,无下腰痛的为对照组.采用t检验或卡方检验进行比较分析. 结果 共纳入飞行人员298人,病例组77人,对照组221人.病例组飞行人员平均年龄高于对照组(t=3.327,P＜0.01),病例组飞行人员35岁以上人员比例较大(58.4％),两组年龄构成比差异有统计学意义(x2=13.698,P＜0.oi).与对照组比较,病例组飞行人员平均体质质数略偏高,但差异无统计学意义.两组人员飞行机种构成差异有统计学意义(x2=15.354,P＜0.01),病例组飞行人员主要集中于运输机(58.8％),而直升机人员相对较少(7.8％);但两组飞行时间差异无统计学意义.病例组飞行人员平均肺活量体重指数[(64.09±11.31)ml/kg]低于对照组[(69.00±10.08)ml/kg],差异有统计学意义(t=3.580,P＜0.01). 结论 在飞行人员中,年龄是下腰痛的重要危险因素,运输机的飞行人员的下腰痛发生率显著高于其他机种.肺活量体重指数显著偏低是下腰痛飞行人员重要的临床特征.“,”Objective To analyze the clinical characteristics of chronic low back pain in flying personnel and to provide evidences for the health intervention to the disease.Methods The physical examination information of the flying personnel who were recuperating in Air Force Hangzhou Aviation Medicine Appraisal and Training Center was collected including age,type of plane,height,weight,and vital capacity.Subjects were divided into case group (with low back pain) and control group (without low back pain).The data were analyzed by independent-samples t-test or Chi-squared test for comparing the difference.Results Two hundred and ninety eight flying personnel were included for analyzing.There were 77 subjects in case group,and 221 subjects were in control group.The average age of the flying personnel of case group was significantly higher than that of control group (t=3.327,P＜0.01).The constituent ratio of the flying personnel older than 35yr in case group(58.4 ％) was higher than that in control group.The difference of age constituent ratio between two groups was significant (x2 =13.698,P＜0.01).The average body mass index of the flying personnel in case group was slightly higher than that in control group but no statistical significance.The difference of constituent ratio in type of plane between two groups was significant (x2 =15.354,P＜0.01).Most flying personnel(58.8 ％) in case group worked for transporter.The helicopter flying personnel took the least (7.8％).However,there was no significant difference on flying hours between two groups.The vital capacity/weight ratio of the flying personnel in case group[(64.09±11.31)ml/kg] was significantly lower than that in control group[(69.00±10.08)ml/kg] (t=3.580,P＜0.01).Conclusions Age is an important risk factor of chronic low back pain in flying personnel population.The incidence of low back pain in the flying personnel of transporter is higher than that of other type of aircrafts.The significantly decreased vital capacity/weight ratio is an important clinical character for the flying personnel with low back pain.
