The Results of multivariate logistic regression analysis showed that regular physical exercise （OR=0.597, 95%CI： 0.359-0.992） was a protective factor for overall obesity;female （OR=2.352,95%CI： 1.685-3.283）was a risk factor of central obesity;public servants or staff from enterprise and institution（OR=0.508, 95%CI： 0.289-0.892）,drinking （OR=0.637,95%CI：0.471-0.860）,salt intake of less than five grams per day （OR=0.590,95%CI：0.434-0.802）and regular physical exercise （OR=0.760,95%CI：0.583-0.991） were protective factors for central obesity. @*Conclusion @#The prevalence rates of overall obesity and central obesity among residents aged 40 years or above in Taizhou were 6.54% and 60.32%, respectively.
