Investigation on the risk factors of metabolic syndrome for the flying personnel

Objective To survey the risk factors of metabolic syndrome (MS) of military flying personnel so as to provide the basis of prevention and control measures.Methods Body mass index (BMI),triglyceride (TG),fasting plasma glucose (FPG) and blood pressure (BP) were measured for 682 flying personnel.Such diagnostic criteria as BMI≥ 25 kg/m2 (obesity),TG≥ 1.7 mmol/L (hypertriglyceridemia),BP≥ 140/90 mm Hg (hypertension),and FPG≥ 6.1 mmol/L (impaired fasting blood glucose,IFG) were chosen based on the criteria issued by China Diabetes Association in 2004.MS was diagnosed in case of the personnel exceeded above 3 or more criteria.Their health history was reviewed upon above mentioned parameters for comparison and analysis.Results The crude prevalence of MS was 6.45％ (44 out of 682 cases).The prevalence of MS was 0.00％,4.73％,18.99％ and 25.00％ respectively corresponding to the flying personnel aged over 20,30,40 and 50 years old.The prevalence of obesity,hyper triglyceride,hypertension,raised fasting blood glucose was 39.44 ％,22.29 ％,8.21％,and 1.61％ respectively.Among which,321 personnel were diagnosed as metabolic disorders based on one or more abnormal parameters.The total prevalence of abnormal metabolic index was 47.07％.Conclusions The prevalence of MS is so high in military flying personnel.Overweight,hyper triglyceride and aging have become the high risk factors to MS.It is necessary to take early intervention for preventing MS.
