The Diabetes Mellitus Prevalence And Associated Risk Factors Among The General Population Over 60 Years Old In Changchun

Objective: To investigate the prevalenceandthe risk factors of pre-diabetes and diabetes mellitus in community residents aged over 60 years in Changchun City and provide theoretical basis for the health management of the elderly in Changchun CityMethod: A total of 2176 people aged 60 and over who were examined in two community hospitals in Changchun during the period from January 2015 to December 2015 were sampled using the cluster random sampling method.The survey includes: residents’ demographi information,past history,physical examination,and laboratory test results.Diagnostic criteria for prediabetes mellitus(PDM)and diabetes mellitus(DM)are based on guidelines published by the American Diabetes Association in 2009.Univariate analysis using chi-square test and rank sum test,univariate analysis of meaningful variables into multivariate logistic regression analysis,Odds ratio(OR)and its 95% confidence interval(95% Confidence Interval,CI).All data were statistically analyzed using SPSS21.0.Results:(1)The study included 2176 subjects,951 normal blood glucose patients,accounting for 43.7%,563 residents in the DM group,the prevalence of DM was25.9%;662 residents in the PDM group,the prevalence of prediabetes was30.4%(2)Gender group: prevalence of DM for men and women was 24.3% and 26.9%,respectively,thus there were no differences among different geder;the detection rate of PDM was 37.9% and 43.1%,respectively.Women were higher than men,the difference was statistically significant.(3)Age group: The prevalence of DM increased with age.The prevalence rates of DM in different age groups(60-64 years,65-69 years,and 70 years and over)were 23.5%,24.8%,and 29.3%,respectively.Statistically significant;PDM detection rates were 41.6%,43.1%,and 38.6%in different age groups(60-64,65-69,and 70 years of age,respectively).The difference was not statistically significant.(4)Culture groupings: primary school and junior group or junior high school group,senior high school group.Above three groups,the prevalence of DM was 22%,26.8%,and 26.5%;the detection rate of PDM was 42.%,42.9%,38.2%,the difference was not statistically significant.(5)The BMI group was in thin,normal,overweight,and obese four groups.The prevalence of DM in different BMI groups was 23.6%,21.8%,27.3%,and 28.4%,respectively;the difference was statistically significant;The PDM detection rates in the different groups were 33.3%,37.8%,41.5%,and 46.3%,respectively,and the difference was not statistically significant.(6)According to whether or not central obesity grouping,the prevalence of DM in central obesity is greater than that in non-center obesity,and the difference between the two groups in PDM detection rate is not statistically significant.(7)According to the exercise time group: the prevalence of DM in the non-exercise group was greater than that in the exercise group,and the difference was statistically significant;the difference in the detection rate of PDM was not statistically significant.(8)The dietary habits were divided into three groups: homogenous meat quality,dietary favoritism,and dietary seizures.The prevalence rates of DM were 25.9%,30.4%,and 25.1%,respectively;the difference was not statistically significant;the prevalence of prediabetes was 42%,50%,and 33.5%,the difference was statistically significant.(9)Differences in prevalence of DM and PDM between smoking and smoking groups were not statistically significant.(10)According to whether drinking group: DM prevalence rate,PDM detection rate of the difference were not statistically significant.(11)According to whether the group was hypertension or not,the prevalence of DM and the detection rate of PDM were higher in the hypertension group than in the non-hypertension group.The difference was statistically significant.(12)In this study,multivariate logistic regression analysis results showed: history of hypertension,older age,overweight,female,high triglyceride(TG),total cholesterol(TC),white blood cell(WBC),high alanine amino Alanineaminotransferase(ALT)is an independent risk factor for DM,and high density lipoprotein cholesterol(HDL-C)is a protective factor for DM;a history of hypertension,high TG,and high ALT are independent risks of PDM,high HDL-C is a protective factor for PDM.Conclusion: The prevalence of DM in this study was 25.9%;the prevalence of PDM was 30.4%;with a history of hypertension,older,overweight,female,high TG,high TC,high WBC,high ALT are independent risk factors of DM,high HDL-C is the protective factors of DM;A history of hypertension,high TG,high ALT are an independent risk factor for PDM,high HDL-C is a protective factor for PDM.
