Objective To investigate the prevalence and risk factors of overweight/obesity and their relationship with dyslipidemia among aerospace professional staff,to provide evidence for more effective health management.Methods Nine hundred eighty aerospace professional staff who took health checkup at our center in 2012 were required to complete a self-report life style questionnaire.Height,body weight and blood lipid profiles of the participants were then measured.Logistic regression was used for data analysis.Results A total of 776 valid questionnaires were finally received.The prevalence of overweight or obesity of the participants were 34.4％ and 10.1％,respectively.Standardized overweight rate was 36.9％ or 36.3％,and standardized obesity rate was 12.3％ or 11.8％,according to Chinese adults' level in 2002 or Beijingers' figure in 2006.Univariate logistic regression showed that age (odds ratio (OR) 2.050,1.666 and 2.164; 95％ confidence interval (CI) 1.490 to 2.820,1.048 to 2.648 and 1.164 to 4.020),gender (OR =0.296,95 ％ CI 0.211 to 0.416),marital status (OR =2.178,95 ％ CI 1.591 to 2.980),cigarette smoking (OR =2.571 and 1.889; 95％ CI 1.061 to 6.229 and 1.341 to 2.660) and alcohol consumption (OR =1.547 and 1.796; 95％ CI0.570 to 4.195 and 1.319 to 2.447) were risk factors of overweight and obesity.In multivariate logistic regression,age (OR =1.562,1.775 and 2.206; 95％ CI 1.029 to 2.372,0.943 to 3.341 and 0.977 to 4.978),female (OR =0.311,95％ CI0.206 to 0.469),marital status (OR =1.591,95％ CI 1.045 to 2.421),meat intake (OR=0.663,95％ CI0.437 to 1.007) and fried food (OR =0.604,95％ CI 0.420 to 0.870) were risk factors of overweight/obesity.The risk of developing hypercholesterolemia,hypertriglyceridemia,low high-density lipoprotein hypercholesterolemia,high lowdensity lipoprotein hypercholesterolemia and hypercholesterolemia were significantly increased in overweight/obese adults.Conclusion Higher prevalence of overweight/obese may alarm the need for aerospace professional staff to initiate body weight control and risk factor prevention,especially for male and married adults.
