Objective: To investigate the relationship between physical activity (PA) and serum lipid level among male taxi drivers of a city in china. Methods: A total of 360 male taxi drivers were collected by two-stage random sampling method from september to november in 2016, the questionnaires were used to survey the status of PA and serum total cholesterol (TC) , triglyceride (TG) , low-density lipoprotein cholesterol (LDL-C) , high-density lipoprotein cholesterol (HDL-C) , according to the recommended standards of the intenational consensus group on physical activity measurement (ICGPAM) , the participants were divided into 3 groups: high PA level group, moderate PA level group and low PA level group. Results: The percentages of individuals with high, moderate and low PA levels were 60.7%, 22.1%and 17.2% respectively, the levels of TG, LDL-C had a declining trend along with the PA level increase, and the level of HDL-C had a increasing trend, the difference was statistically significant (P<0.05). Compared with low PA group, the incidence of dyslipidemia in high PA group showed a declining trend in the indexes of TG, LDL-C, any kind of dyslipidemia and any two kinds of dyslipidemia, the difference was statistically significant (P<0.05). After controlling the potentially confounding effects, compared with low PA group, the risk of dyslipidemia were reduced in the indexes of TG (OR=0.68, 95%CI: 0.55-0.84) , LDL-C (OR=0.67, 95%CI: 0.54-0.83) , HDL-C (OR=0.70, 95%CI: 0.56-0.88) , any kind of dyslipidemia (OR=0.65, 95%CI: 0.54-0.85) , any two kinds of dyslipidemia (OR=0.68, 95%CI: 0.55-0.86) in high PA group, there were significant differences between of them (all P<0.05) . Conclusion: The PA level of male taxi drivers in this city is relatively low, and high PA can reduce the risk of dyslipidemia.
