Prevalence And Influencing Factors Of Metabolic Syndrome Among The Adults In Some Cities Of Poyang Lake Region In Jiangxi Province

Objective:To understand the prevalence and influencing factors of metabolic syndrome in Poyang Lake region,investigate the pathogenesis regularity and trend,and provide scientific inferences for the prevention strategy.Methods:A total of 2187 18~88 years old adults were selected randomly for enquiry in Poyang Lake region including Nanchang,Jingdezhen,Jinxian and Poyang,and relevant indicators were tested by physical examination and laboratory.Using Excel2010 software to built database,and applying SPSS 24.0 software to analyze the relationship between the prevalence of metabolic syndrome and its influencing risk factors.Results:1.The prevalence rate of MS in Poyang Lake region was 12.9%,17.26%for males and 8.92%for females,There was statistically significant difference(X~2=31.070,P<0.05).2.Along with the age increased,the trend of prevalence was increasing.Among different age groups the difference about MS prevalence rate between males and females was diminishing.The highest prevalence of MS was in 70~years old group.the highest prevalence of metabolic syndrome in men,in women and the general population were 70~years old group.3.Male prevalence was higher than female in every component of MS,the morbidities of various component were central obesity(21.65%vs 19.64%,X~2=1.242,P>0.05),high blood pressure(53.77%vs 35.10%,X~2=70.858、P<0.05),hyperglycemia(15.27%vs 10.63%,X~2=9.671、P<0.05),raised TG(38.81%vs22.39%,X~2=64.094、P<0.05),reduced HDL-C(13.39%vs 8.06%,X~2=15.002、P<0.05).The most important component of MS was high blood pressure which accounted for 43.98%of the total variance,then 30.20%for raised TG,20.60%for central obesity,12.84%for hyperglycemia,10.6%for reduced HDL-C.The more the components are superimposed,the less of the MS prevalence.4.Unconditional logistic regression analysis revealed that there were positive correlation between age(B=0.017,P=0.045),TG(B=0.189,P<0.001),systolic blood pressure(B=0.021,P<0.001),diatolic blood pressure(B=0.026,P=0.005),FPG(B=0.424,P<0.001),waist circumference(B=0.157,P<0.001)and MS,which were risk factor for MS;there was negative correlation between HDL-C(B=-1.466,P<0.001)and MS,which can be regarded as protective factor for MS.Conclusion:1.The prevalence rate of MS in Poyang Lake region was 12.9%,17.26%for males and 8.92%for females.2.MS prevalence rate increased with age.3.Male prevalence was higher than female in every component of MS.4.MS influencing factors were age,TG,systolic blood pressure,FPG,waist circumference.MS protective factor was HDL-C.5.The prevalence of MS is relatively high,MS has become the an important health problem.Influencing factors(BMI,hypertension,hyperglycemia,dyslipidemia)should be controlled to reduce or postpone the complications.
