Objective To investigate the prevalence and influencing factor of metabolic syndrome(MS)in rural elderly population. Methods With randomized cluster sampling,investigations including questionnaires,physical examination,fasting plasma glucose,blood lipids were performed in rural population aged over 60 years in Changzhou city in 2004-2005. Results A total of 4976 elderly people were enrolled in the study.The prevalence of MS was 24.1%,and 10.3%in men,34.3%in women by international diabetes federation(IDF)2005 definition.86.2%individuals had one or more of the metabolic disorders.Logistic regression analysis showed that sex,smoking,sweetmeat,family history of essential hypertension(EH)and tea drinking were influencing factors of MS. Conclusions The prevalence of MS is high in rural elderly population,especially in females.

Objective To evaluate the impacts of comprehensive diabetes intervention to provide evidence for effective diabetic control in rural communities.Methods Diabetic patients from four communities at Wujin District of Changzhou City were selected.One hundred and seventy-three patients from two communities received comprehensive intervention,including medication therapy,diabetes education,and diet.exercise,and behavior instruction(intervention group);142 patients from the other two communities got medication therapy only (control group).All the participants were interviewed with structured questionnaire and phyrsical examination.The second epidemic investigation was conducted at 4 years to evaluate the effects of the intervention.Results At the end of the intervention,the awareness rates of normal fasting plasma glucose,major diabetes risk factors,healthy diet,and therapeutic strategies in the intervention group were 90.8%.74.6%,89.6%,and 59.5%,respectively,which were significantly higher than those in the control group (all P<0.05).For the intervention group,the rates of diet behavior or physical exercise change were 68.8% and 58.4%.respectively.which were much higher than those of the control group(all P<0.05).The average levels of systolic pressure,diastolic pressure,fasting plasma glucose,and total cholesterol were (130.6±10.4)mm Hg(1 mm Hg=0.133 kPa),(78.4±7.5)mm Hg,(6.2±3.1)mmol/L,and (4.5±0.9)mmol/L,respectively,in the intervention group,which were lower than those in the control group(all P<0.05).Conclusion Comprehensive intervention shows significant effects on rural community patients with diabetes.

ObjectiveTo investigate the association of lipid ratios with diabetes and pre-diabetes in residents aged 35-75 years in Changzhou City. MethodsA multistage whole-group random sampling method was used to survey permanent residents aged 35-75 years in Tianning and Wujin districts of Changzhou City， and the study data were obtained by questionnaires， physical examination and laboratory tests. The relationship between lipid ratios and diabetes and pre-diabetes was analyzed by dichotomous logistic regression method. ResultsThe prevalence of diabetes in the surveyed population in Changzhou was 18.69%， and the prevalence of pre-diabetes was 10.53%. In the total population， the risk of pre-diabetes was significantly increased in the highest TC/HDL-C， TG/HDL-C and LDL-C/HDL-C groups， by 68%， 93% and 38%， respectively； the risk of diabetes was also significantly increased in the highest TC/HDL-C， TG/HDL-C and LDL-C/HDL-C groups， by 105%， 149% and 78%， respectively. The risk of diabetes was also significantly increased in the highest TC/HDL-C， TG/HDL-C and LDL-C/HDL-C groups， by 105%， 149% and 78%， respectively. All three lipid ratios increased in women compared to men， leading to a stronger association with increased risk of diabetes and pre-diabetes. ConclusionLipid ratios TC/HDL-C， TG/HDL-C， and LDL-C/HDL-C were correlated with the risk of diabetes and pre-diabetes in people aged 35-75 years， with TG/HDL-C having the strongest association with diabetes and pre-diabetes， and is expected to be a key predictor for assessing the development of diabetes.
