Epidemiological Analysis Of Glucose Metabolism Disorder In People Over 35 Years Old In Qingdao City

Objective To clear the prevalence of impaired glucose regulation(IGR) and diabetes mellitus(DM) in residents over the age of35in Qingdao City and explore the influencing factors of them.Methods Multi-stage stratified random sampling method was used. A total of6069subjects were investigated. All of them received questionnaires, physical examinations and laboratory tests. Univariate and multivariate non-conditioned logistic regression was performed by SPSS17.0to assess the factors of IGR and DM.Results In the5683subjects,there were2150males (37.8%) and3533females (62.17%). The standardized prevalence of impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and DM were15.91%,18.81%and15.96%,respectively. The prevalence of IGT and DM were gradually increasing with aging. The highest prevalence of IFG was in group of60s(19.78%) and the lowest was in group of below40s(14.21%). Though both the prevalence of IFG and DM in male were significantly higher than that in female, prevalence of IGT was lower than that in female.Prevalence of IFG, IGT and DM showed tendency to decrease with increased educational level, and group of illiterate had highest prevalence among all of them,19.88%,24.91%and20.60%,respectively. Group of college degree and above had the lowest prevalence in IFG(12.54%) and IGT(11.855),while the lowest prevanlence of DM(13.06%) was in group of junior middle school. Multivariate logistic regression analysis showed that, as to IFG, obesity, hypercholesteremia, hypertriglyceridemia, hypertension and alcohol drinking were risk factors, female and high educational level were protective factors. Aging, overweight or obesity, central obesity, hypertriglyceridemia and hypertension were risk factors of IGT. Aging, overweight or obesity, central obesity, hypercholesteremia, hypertriglyceridemia, hypertension, family history of diabetes and history of stroke were risk factors of DM.Conclusion The prevalence of IGR and DM is severe in residents over the age of35in Qingdao City. More attention should be paied to the related risk factors.
