A Study On Prevalence Of Metabolic Syndrome In Tianjin Community Residents Aged Fifty And Older And Associated Factors

Objective:To investigate the prevalence and associated factors of Metabolic Sydrome (MS) in residents aged fifty and older.Methods:A cross-sectional study was conducted from October,2008 to Match,2009 in Tianjin.4577 subjects aged fifty and older and having lived in Tianjin over 5 years were recruited by means of cluster sampling. Information was collected through face-to-face interview, which including demographic data, behavior pattern, disease history, physical examinations and laboratory examinations. The patients with metabolic syndrome (MS) were diagnosed according to the diagnostic criteria of International Diabetes Federation in 2005. Univariate and multivariate non-conditional logistic regression were used to analyse odds ratio and its 95 percent of confidence interval for exploring the associated factors with MS, in which case group consisting of MS patients and control group consisting of non-MS controls.Results:There were 1838 patients with MS in 4577 subjects. The prevalence of MS was 40.16%. The results of univariate logistic regression analysis showed that age (OR=1.102,95%CI:1.021-1.189), average income per month (OR=1.091,95%CI: 1.013-1.714), family history of hypertension (OR=1.78,95%CI:1.546-2.067), family history of diabetes (OR=1.810,95%CI:1.352-2.423), wsist-to-hip ratio (OR=1.370, 95%CI:1.287-1.460) and body mass index (OR=2.397,95%CI:2.198-2.614), dyssomnia (OR=1.274,95%CI:1.106-1.477) were associated with higher risk for MS; and male (OR=0.571,95%CI:0.506-0.644), education level (OR=0.882,95%CI: 0.819-0.950), smoking (OR=0.728,95%CI:0.641-0.826), drinking (OR=0.801, 95%CI:0.678-0.946), meat intake (OR=0.921,95%CI:0.859-0.988) and fish intake (OR=0.902,95%CI:0.830-0.980) were associated with lower risk for MS. The results of multivariate logistic regression analysis showed that age (OR=1.192,95%CI: 1.096-1.298), average income per month (OR=1.090,95%CI:1.005-1.182), family history of hypertension(OR=1.619,95%CI:1.382-1.895), family history of diabetes (OR=1.600,95%CI:1.165-2.199), body mass index (OR=2.284,95%CI:2.089-2.497), waist-to-hip ratio (OR=1.334,95%CI:1.246-1.428), dyssomnia (OR=1.183,95%CI: 1.015-1.378) were associated with higher risk for MS; male (OR=0.514,95%CI: 0.450-0.587) was associated with lower risk for MS.Conclusions:The prevalence of MS in study population was 40.16%. Gender, age, average income per month, family history of hypertension, family history of diabetes, body mass index, waist-to-hip ratio, dyssomnia were associated with risk for MS.
