Abstract:
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.
