RESUMO
Objective@#To investigate the prevalence and related factors of obesity and central obesity among 35-75 year-old population in Jiangsu Province. @*Methods@#During 2015-2017,83 530 eligible subjects aged 35-75 years from six study sites of Jiangsu Province were interviewed and examined. The data of demography,lifestyles,disease history,height,weight and waistline were collected. Logistic regression analysis was conducted for the influencing factors for obesity and central obesity.@*Results@#A total of 83 393 residents completed the study,with a response rate of 99.84%. The prevalence of overweight,obesity and central obesity was 43.35%（standardized rate：35.90%）,20.02%（19.48%）and 59.93%（57.03%）. The results of multivariate logistic regression analysis showed that females（OR=0.822,95%CI：0.786-0.859;OR=0.900,95%CI：0.851-0.952;OR=1.130,95%CI：1.083-1.179）,45-75 years old（OR：1.120-1.731,95%CI：1.102-1.881）,graduating from high school or above（OR：0.767-0.902,95%CI：0.721-0.943）,living in urban areas（OR：1.530-2.077,95%CI：1.284-3.007）,smoking（OR：0.724-0.855,95%CI：0.678-0.898）,drinking （OR：1.125-1.179,95%CI：1.076-1.235）,hypertension（OR：1.884-3.461,95%CI：1.821-3.613）,diabetes（OR：1.363-1.758,95%CI：1.305-1.851）, dyslipidemia（OR：1.478-1.870,95%CI：1.429-1.851）were associated with overweight,obesity and central obesity. @*Conclusion@#The standardized prevalence rates of overweight,obesity and central obesity among 35-75 year-old population in Jiangsu Province are 35.90%,19.48% and 57.03%,respectively. Gender,age,education,residence,smoking,drinking,hypertension,diabetes and dyslipidemia are related factors.
