Abstract: ObjectiveTo explore risk factors of impaired glucose regulation(IGR)and diabetes mellitus(DM) among residents of Shandong province and to provide evidence for the intervention of the disease.MethodsUsing multistage stratified cluster random sampling method,15 262 residents were investigated with a standard questionnaire and the measurements of height,weight,waist circumference,hip circumference,and blood pressure.ResultsTotally 1 618,262 and 941 cases of impaired fasting glucose(IFG),impaired glucose tolerance(IGT),and DM were detected with the weighted prevalences of 9.34% (95% confidence intervalCI:6.58-12.10),1.53% (95%CI:1.09-1.98),and 5.50% (95%CI:4.51-6.48).At the age of more than 40 years,hypertension,waist circumference exceeding the standard,and overweight were risk factors for IFG;having occupational physical labor more than 6 hours was protective factors for IFG.At the age of more than 40 years,hypertension,waist circumference exceeding the standard,and overweight were risk factors for IGT.At the age of more than 40 years,hypertension,waist circumference exceeding the standard, overweight,chronic disease history,and having occupational physical labor more than 6 hours were risk factors for DM.ConclusionAt the age of more than 40 years,hypertension,waist circumference exceeding the standard,and overweight were common risk factors for IGR and DM.
