Objective:By cross-sectional survey and risk factors analysis for the prevalence of diabetes mellitus(DM)of the population over the 18 years of age in Dalian urban and rural areas,it could be provide a scientific basis to carry out health education of DM and prevention work in this areas in the future.Patients and methods:1.Study samples:This study used multistage stratified cluster random sampling method.In September to May 2015 we were selected Nan shidao street community of Xi gang district、lotus area、Xin hua community and Dalian Medical University student apartments as urban survey site,and selected furnace village、West Road、East Street、Sha Ling farm、Dong Jia villages、Shuang Li villages、the five senior middle school under the jurisdiction of Qing Dui town of Zhuang he City of

2670 people,including 1405 people in the urban,1265 people in the countryside,male to female ratio close to 1.03:1,and the composition ratio of age close to ratio of the proportion of the national population census in 2010.2.Research methods:All subjects were investigated:record the name,age,gender,educational level,occupation,household income,smoking history,family history of DM,personal history of DM and high blood pressure.Physical examination:measurement of height,body weight,waist circumference,blood pressure,body mass index(BMI).Tests:All subjects were measured fasting plasma glucose(FPG),glycosylated hemoglobin,blood lipids(total cholesterol,triglycerides,low density lipoprotein cholesterol,high density lipoprotein cholesterol,serum uric acid),the persons who had not been diagnosed with DM were do the 75g oral glucose test,measured after 2 hours of glucose(2hPG).Using the data of 2010 population census of Dalian standard the prevalence.Statistical analysis was performed using SPSS 17.0 statistical software.3.Diagnostic criteria:DM:Hospital above the county have diagnosed diabetes;FPG≥7.0mmol/l;2hPG≥11.1 mmol/l;HbA1c≥6.5%.Prediabetes:impaired fasting glucose(IFG):5.6 mmol/l≤FPG<7.0mmol/l and 2hPG<7.8 mmol/l;impaired glucose tolerance(IGT):7.8 mmol/1 ≤2hPG<11.1mmol/l and FPG<5.6mmol/l;IFG and IGT;5.7%≤HbA1c<6.4%.Overweight,obesity and central obesity:obesity:BMI≥30kg/m2,overweight:25kg/m2≤BMI<30kg/m2;central obesity:male waist circum≥90cm,female waist circum≥80cm.Hypertension:Hospital above the county have diagnosed hypertension;systolic blood pressure≥140mmHg and/or diastolic blood pressure≥ 90mmHg.Results:1.The prevalence of DM in the population over 18 years old in Dalian was 12.9%,after standardizationand was 11.8%.The prevalence of prediabetes was 27.5%,after standardizationand was 24.3%.2.Different areas:In urban the prevalence of DM was 15.0%,in rural it was 10.6%.The prevalence of DM in the urban was higher than rural(P<0.05).In urban the prevalence of prediabetes was 27.5%,in rural it was 14.9%,between urban and rural it was no significant difference(P>0.05).3.Different gender:The prevalence of DM of male and female were 14.3%、11.5%separately,the prevalence of DM male was higher than female(P<0.05),Stratification in different regions:In urban the prevalence of DM of male and female were 17.2%、12.6%,the prevalence of DM male is higher than female(P<0.05);In rural the prevalence of DM of male and female were 11.0%、10.1%separately,between male and female it was no significant difference(P>0.05).In urban the prevalence of prediabetes of male and female were 29.4%、25.6%,betweem male and female it was no significant difference;in rural the prevalence of prediabetes of male and female were 28.5%、26.4%,betweem male and female it was no significant difference(P>0.05).4.Different ages:The prevalence of DM increased with age(P<0.05),50 years of age or older population was subject population of DM patients,while prediabetes patients were younger than DM patients(P<0.05).5.Among the prediabetes the IFG accounted for the highest proportion.6.The prevalence of DM awareness in urban was 58.3%,in rural was 43.3%,there was no significant difference between urban and rural areas(P>0.05).The prevalence of DM awareness of male was 51.5%,female was 48.5%,there was no significant difference between male and female(P>0.05).7.The prevalence of DM patients who has controlled their blood glucose in urban was 59.7%,in rural area was 69.4%,there was no significant difference between urban and rural areas(P>0.05).The prevalence of DM patients who has controlled their blood glucose of male was 61.9%,female was 65.6%,there was no significant difference between male and female(P>0.05).8.Multivariate logistic regression risk factors analysis showed that age,urban,the junior middle school and below education,overweight,family history of DM,overweight,obesity,central obesity,high blood pressure,waist circumference,cholesterol were the risk factors of DM and prediabetes(P<0.05).Conclusions:1.The standarded prevalence of DM of adults in Dalian was 11.8%,and it have growing trend,need we to strictly control.2.The standarded prevalence of prediabetes of adults in Dalian was 27.5%and it was lower than the overall level of our country,but compared with the past,there was a significant increase trend.In the future there will be most of prediabetes patients developping to DM.The prevention of DM work need to do attention.3.Age,family history of DM,the junior middle school and below education,overweight,obesity,abdominal obesity,hypertension,waist circumference,cholesterol were risk factors of DM and prediabetes.Body weight and blood pressure control was the core part of the diabetes prevention.
