Abstract:
BACKGROUND: The cluster of multiple metabolic disorders, namely raised blood pressure, overweight or obesity, raised triglyceride level, reduced high density lipoprotein cholesterol (HDL-C) level were the predictor of type 2 diabetes mellitus (DM). However, similar data especially the old people's data is relatively rare in China.OBJECTIVE: To analyze the relationship between the components of metabolic syndrome (MetS), their clusters and the risk of diabetes among Chinese old population.DESIGN: Cross-sectional study.SETTING :Beijing Institute of Geriatrics, Beijing Hospital, Ministry of Public Health.PARTICIPANTS: The study was carried out from February 2001 until November 2001.4 499 volunteers aged 60 and over were recruited from the academic institutes in Beijing Xicheng, Haidian and Shijingshan districts through cluster sampling methods. They were selected after excluding those who did not have integral data.METHODS: Diabetes was considered when fasting glucose was ≥7.0 mmol/L and was treated for or diagnosed as DM. Chi-square tests were performed to compare the categorical data. Age and sex adjustment were taken in the comparison of the levels of blood pressure, waist circumference (WC), The body mass index (BMI), and lab variables, Multifactor stepwise (backward)Logistic regression analyses were used to select the factors which would have association with the risk of DM. When analyzing the relationship between number of clustering of the traits of MetS and DM, the group without any metabolic abnormalities was set as control group. The dummy variables were set for 1,2,3,4 clusters of metabolic abnormalities. The Logistic regression model was used again to test the relationship and adjusted by age and the family history of DM.MAIN OUTCOME MEASURES: The blood glucose, waist, BMI, blood pressure, triglyceride (TG), HDL-C, and family history of diabetes of subjects.RESULTS: 4 444 people in the mean age of 65±5 were retrieved. 556cases of DM were found in this survey. Age, family history of diabetes,systolic blood pressure, waist and TG were independently associated with the risk of DM, with OR (95%CI) being 1.02 (1.00-1.04), 3.48(2.76-4.39), 1.02 (1.01-1.02), 1.03 (1.00-1.03), 1.13 (1.05-1.21), respectively. When TG was not in the model, HDL-C was also inversely associated with DM (OR=0.67, 95%CI 0.49-0.91). The risk of DM increased with clustering of abdominal obesity, raised blood pressure, raised TG, and reduced HDL-C level in individuals.CONCLUSION: In addition to age and genetic factors, metabolic factors, especially their clusters are closely related to the risk of diabetes. Therefore, the features of MetS are important indicators for the risk of DM in aged people.
