Abstract:
Objective To investigate and analyze the snoring disease incidence,moderate and severe snoring disease incidence rate,the risk factors and their relationship to daytime lethargy in civil flying personnel.Methods The cluster sampling method was chosen.A questionnaire survey was conducted for 1 400 civil flying personnel.Items of questionnaire included general information (personal name,gender,age,education),physiological parameters (height,weight,neck circumference,waist circumference and blood pressure),smoking and drinking history,chronic disease history,family history of snoring,cognition of snoring,snoring severity score,Epworth sleepiness score (ESS) scale as well as sleep related flight data (flight course,type of aircraft,flying jet lag,total flying hours and flying hours per year),and calculated body mass index.The effective questionnaires were statistically analyzed,and the prevalence of snoring and the prevalence of moderate and severe snoring were calculated.The risk factors associated with snoring were screened.The snoring degree was assessed according to Guidelines for the Diagnosis and Treatment of Obstructive Sleep Apnea Hypopnea Syndrome (2011 Revision).According to the degree of snoring,the patients were divided into non snoring group,mild snoring group and moderate or severe snoring group.The score of ESS in different snoring groups was compared.Results Totally 1 356 questionnaires were collected and 1 227 questionnaires were valid.The valid rate of the questionnaire was 90.5％.Subjects included 1 206 male flying personnel and 21 female flying personnel.The snoring prevalence rate of male flying personnel was 60.0％ (723/1 206)and the moderate or severe snoring prevalence rate of male flying personnel was 14.8％(179/1 206).No snoring was found in female flying personnel.For the male flying personnel older than 30 years old,the snoring prevalence rate was 64.5 ％ (402/623),and the moderate or severe snoring prevalence rate was 19.4％oo (121/623).The prevalences of snoring and moderate or severe snoring increased with age and BMI(x2 =19.714-38.964,P＜0.01).Prevalences of snoring and moderate or severe snoring increased with the increase of smoking and alcohol consumption (x2 =15.969-58.919,P ＜ 0.01).Age,BMI,neck circumference,waist circumference,smoking and drinking habits and family history were the risk factors of snoring.For flight factors the jet lag was the risk factor of snoring.The significant differences of daytime ESS score between non snoring group and snoring groups were found(F=6.126,P＜0.01).Conclusions The snoring prevalence of male civil flying personnel is related to age,BMI,neck circumference,waist circumference,smoking and drinking habits,family history and flight jet lag.The severer snoring the higher ESS score obtained.It should be highly regarded.
