title: [Association between sedentary life style and risks of metabolic syndrome and diabetes mellitus type 2].
abstract: OBJECTIVE
  To explore the association of sedentary life style with risk of metabolic syndrome (MS) and diabetes mellitus type 2(T2DM).
  
  
  METHODS
  A total of 6 016 local residents aged 18 years or older in Fujian province were recruited by multi-stage stratified cluster sampling method in 2010-2011. Data, including demographic information, physical activity and sedentary time were collected. Indices related to height, weight, waist circumference, blood pressure and blood lipid were determined while MS and T2DM were diagnosed by IDF (2005) and WHO (1999) criteria. Logistic regression was used to estimate the correlations between sedentary behavior and MS or T2DM.
  
  
  RESULTS
  The prevalence rates of MS and T2DM were 19.0% and 8.0% respectively, in local residents aged 18 years or older, in Fujian province. The overall rate of sedentary behavior was 18.1%, with the mean sedentary time as 4.3 hours. Both data showed significantly differences (P < 0.001) among control group,MS without T2DM group,MS with T2DM group and T2DM without MS group. Compared with the group of sedentary time <2.0 h/d, 1) the group with 2.0-3.5 h/d was significantly correlated with MT group (OR = 1.44, 95% CI:1.03-2.03, P < 0.05), 2) groups of 3.5-6.0 h/d and ≥6.0 h/d were significantly correlated with M, T, MT group, respectively (OR:1.49-1.76 and 1.28-1.58 respectively, 95% CI:1.19-2.45 and 1.02-2.23 respectively, P < 0.05), and 3) sedentary behavior was independently associated with an increased risk of MT group (OR = 1.82, 95% CI: 1.33-2.48, P < 0.01) and M group (OR = 1.43, 95%CI:1.14-1.78, P < 0.01), after the adjustment for factors as age, sex, cigarette smoking, alcohol drinking,BMI, education, occupation, sedentary behavior/sedentary time.
  
  
  CONCLUSIONS
  MS and T2DM were associated with sedentary lifestyle, but these findings should be confirmed through further longitudinal studies.
