Correlation between ways of transportation to work and health in Beijing workers

Driving car or taking taxi to work is getting a usual way among Beijing workers who used to work by foot or bicycle. Our study is to explore the correlation between ways of transportation to work and the levels of serum lipids among these workers. During a period between January and February 2006, telephone interviews were made to 2,506 randomly selected the urban residents, aged 18 years or older in the eight districts of Beijing using a multiple stratified random sampling. Particularly, the information on duration and intensity of physical activities and transport behavior was collected. In the selected individuals, 1,024 (40.86%) workers who subscribed the informed consent documents, were subsequently requested to accept the tests of bio-markers, i.e., total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL-C), and low-density lipoprotein (LDL-C).Multiple logistic regression model was employed to analyze the influence of ways of transportation to work on the levels of serum lipids among Beijing workers. The risk of dyslipidemia in the workers who go to work by bus, driving car or taking taxi is higher than that of the workers who walk to work. The ORs are 1.99 (95%CI: 1.33-2.97) and 2.21(95%CI: 1.28-3.84), respectively. Whereas there is no significant difference in the risk of suffering dyslipidemia when the workers who ride bicycles compared with those walk to work (OR=1.22, 95%CI�F0.83-1.78). The study, therefore, shows that individuals, who walk or ride bicycles, have lower prevalence of dyslipidemia than those who take bus and drive car or take taxi when adjusted for gender, age, BMI, smoking and edible oil intake.ways of transportation to work  dyslipidemia  multiple logistic regression
