Objective To study the prevalence of hypertension in flying personnel,and'o identify the main influencing factors related to hypertension.Methods Review was conducted on physical check-up data in 1 070 flying personnel,and a questionnaire survey was answered by flying personnel.The interclass data were processcd by chi square test,and the risk factors related to hypertension were analyzed with Logistic regression by SPSS 13.0 software.Results In 1 070 flying personnel,there were 76 persons belong to hypertension group and took 7.10％.There were 401 persons (37.48％) in normal group.There were 593 persons (55.42％) in normal but on high side.There was no statistical significance of the incidence of hypertension among different flying duties and type of aircrafts (P＞0.05).The predictive factors of hypertension included age (OR=1.415,95％ CI:1.069～1.874,P＜0.05),BMI (OR=2.501,95％CI:1.915～3.266,P＜0.01),waist circumference (OR=2.235,95％CI:1.723～2.897,P＜0.01) and hypercholesterolemia (OR=1.372,95％CI:1.043～ 1.804,P＜0.05).Conclusion The prevalence of hypertension in 1 070 flying personnel is lower than that in common people.Age,overweight or obesity,hypercholesterolemia would be the significant risk factors for hypertension.It is no statistical significance of the incidence of hypertension among different flying duties and type of aircrafts.

Objective To investigate the relationship between obesity parameters and obstructive sleep apnea-hypopnea syndrome (OSAHS) in aircrew. Methods A questionnaire survey in aircrew members was performed. Outcome measurement included body height, body weight, neck circumference ( NC), waist circumference (WC), and body mass index (BMI). Those with snoring during sleep and/or Epworth sleepiness scale (ESS)score ≥ 9 were screened with pulse oxygen saturation test during overnight sleep. Those with oxygen saturation decrease index ≥ 10 times/h and suspected OSAHS were tested by polysomnography (PSG). The objects were then assigned to three groups: the OSAHS group,the snore group and the normal group. The relationship between obesity parameters and OSAHS was analyzed. Results There were 399 ( 37. 54% ) overweight, 36 ( 3. 39% ) obesity, 130 ( 12. 23% ) increased NC, and 354 (33.30%)increased WC in 1063 aircrew members (OSAHS group ＞ snore group ＞ normal group; P＜O. 05). The mean value of BMI, NC and WC in the three groups were dittos. Multiple logistic regression analysis showed that overweight, obesity and increased WC were significantly associated with snoring (P ＜0.05) and snoring enlarged NC was significantly correlated with OSAHS (P＜ 0.05). Conclusion Increased BMI, NC and WC may be risk factors of OSAHS among aircrew. Effective prevention and treatment of OSAHS should be needed.
