Prevalence Of Metabolic Syndrome In Adult Residents Of Jiangxi Province

Objective:Metabolic syndrome promotes the development of cardiovascular disease and type 2 diabetes.It compromises health condition seriously.We did the investigation about the prevalence of metabolic syndrome in adult resisdents of Jiangxi Province during the period of April to August in 2015.The aim of our study was to provide scientific data for prevention and control of metabolic syndrome in Jiangxi Province including the overall prevalence of adult residents,risk factors associated with metabolic syndrome and the relationship between BMI(Body Mass Index)and different metabolic components.Methods:2665 adult residents were included in our study which were selected as a representative population of rural and urban regions by cluster sampling.Each subject would have finished three parts of investigations,as questionnaire,physical measurement and blood tests.Metabolic syndrome can be defied according to two kinds of criteria----IDF 2005 criterion and CDS 2004 criterion.WGOC criterion was used to identify obesity.Results:1.According to IDF criterion,the crude prevalence of metabolic syndrome was21.0%and the age standardized prevalence was 21.06%.When divided into six age groups(18 to 29,30 to 39,40 to 49,50 to 59,60 to 69,70 and over),the prevalence of each group was 4.2%,18.5%,24.3%,33.6%,37.4%,30.6%respectively.The prevalence was increased with age(?~2=173.752,P<0.001)and women over 60 years old had the highest rate.There was no significant difference between male(19.55%)and female(22.66%)incidence rate(?~2=3.636,P=0.057).The prevalence reached23.90%and 18.45%in rural and urban areas respectively and rural area had a higher rate compared to urban area(?~2=11.946,P=0.001).Female prevalence of rural region was higher than that of urban region in the following age groups,18 to29(?~2=8.048,P=0.005),40 to 49(?~2=12.899,p<0.05)and 50 to 59(?~2=7.635,P=0.006).2.According to CDS criterion,the crude prevalence of metabolic syndrome was15.1%and the age standardized prevalence was 15.2%.When divided into six age groups(18 to 29,30 to 39,40 to 49,50 to 59,60 to 69,70 and over),the prevalence of each group was 0.9%,11.0%,15.8%,24.4%,35.0%,30.1%respectively.The prevalence was increased with age and people over 60 years old reach to the highest rate.There had significant difference between male(17.12%)and female(13.01%)incidence rate(?~2=8.276,P=0.004).Men had a higher prevalence than women.The prevalence reached 13.54%and 16.96%in rural and urban areas respectively and rural area had a higher rate compared to urban area(?~2=5.644,P=0.018).Female prevalence of rural region was higher than that of urban region in the following age groups,40 to 49(?~2=4.393,P=0.036),50 to 59(?~2=5.727,P=0.017)and over 70years old(?~2=4.561,P=0.033).3.Multiple logistic regression analysis was performed to calculate adjusted odds ratios(OR)for metabolic syndrome risk factors,as the following factors considering attribute to the disease,female,age over 40 years old,education level below high school or technical secondary school,family history of diabetes mellitus,high fasting glucose,hypertension,dyslipidemia,hyperuricemia,overweight or obesity,high waist circumference.4.According to the analysis between the relationship between BMI and the morbidity rate of metabolic syndrome as well as metabolic disorders,both rate increase with the development of BMI.BMI had a positive correlation with systolic pressure,diastolic pressure,fasting blood glucose,triglyceride,total cholesterol and serum uric acid,however a negative correlation reveals with high density lipoprotein.Conclusion:1.According to IDF and CDS criterion,the age standardized prevalence of metabolic syndrome is 21.05%and 15.2%respectively.2.Metabolic syndrome risk factors in Jiangxi province are female,age over 40years old,education level below high school or technical secondary school,family history of diabetes mellitus,high fasting glucose,hypertension,dyslipidemia,hyperuricemia,over weight or obesity and high waist circumference.3.The morbidity rate of metabolic syndrome as well as metabolic disorders increase with the development of BMI.BMI had a positive correlation with systolic pressure,diastolic pressure,fasting blood glucose,triglyceride,total cholesterol and serum uric acid,however a negative correlation reveals with high density lipoprotein.4.The prevalence of metabolic syndrome is pandemic in Jiangxi province and community-based strategy for prevention and treatment should be settled down as soon as possible.Medical workers should take positive part in health education and call for healthy lifestyle.
