Methods A total of 3 756 participants were enrolled. Each participant underwent an oral glucose tolerance test and completed a questionnaire. Anthropometric indices were recorded and serum samples were collected for measurement. Results Liver enzymes concentrations were independently associated with i-IGT, iFG+IGT, and diabetes. With the increase of ALT and GGT concentrations, ORs for i-IGT, IFG+tGT, and diabetes increased gradually. By comparing patients in the highest quartile of GGT concentrations or ALT concentrations with those in the lowest quartile (Q1), ORs for iqGT, IFG+IGT, or diabetes was significant after adjustment. Both ALT and GGT concentrations were linearly correlated with HOMA-IR and independently associated with HOMA-IR [ALT OR (95% Cl): 2.56 (1.51-4.34) P=0.00; GGT OR (95% CI): 2.66 (1.53-4.65) P=0.00]. Conclusion Serum ALT and GGT concentrations were closely related to pre-diabetes and diabetes in the Shanghai population and positively associated with insulin resistance.展开更多

This study aimed to investigate MetS' prevalence and its impact on the CVD incidence in this specific population group. Methods A data set of a community-based prospective cohort study was analyzed. A total of 2300 subjects aged 40-94 years were followed up for the CVD events. MetS defined according to the JCDCG criteria was assessed at baseline, and the middle-aged and elderly groups were classified by the WHO definition. Results As compared with the middle-aged group, the prevalence of MetS increased by 0.6 times (34.6% vs. 21.3%) and the incidence density of CVD increased by 4.9 times in the elderly group (52.3/1000 person-year vs. 8.9/1000 person-year). Furthermore, the multivariate Cox regression revealed that the risk to CVD incidence was independently related to increased waist circumference in the middle-aged group (HR=2.23, P〈0.01) and to elevated blood glucose in the elderly group (HR=1.39, P〈O.01). Conclusion MetS was highly prevalent in middle-aged and elderly Chinese. MetS significantly increased the risk to OdD incidence in the elderly. All individuals with metabolic disorders should receive active clinical care to reduce the incidence of CVD.展开更多
