RESUMO
Objective To investigate the prevalence and distribution of pre-diabetes and diabetes mellitus in Han population aged over 60 years in Urumqi. Methods The physical examination and 75 g oral glucose tolerance test (OGTT) were performed in 2210 people, including 1231 elderly people aged over 60 years (old age group) and 951 people aged 40-59 years (middle age group). The diagnosis of diabetes mellitus was established according to WHO criteria in 1999. Results In Han ethnic people, the prevalence rates of diabetes mellitus and pre-diabetes were 32.2% and 29.0% respectively in old age group, and were significantly higher than in middle age group ( 12.3% and 20.9%,x2= 192.62, P＜0.05). The prevalence rates of impaired glucose tolerance (IGT) were higher in old age group than in middle age people (21.6% vs. 13.9%, x2 = 20.97, P＜0.05), but there was no significant difference in the prevalence rate of impaired fasting glucose (IFG) between the two groups. The prevalence rate of metabolism syndrome (MS) was higher in old age group than in middle age group (52.2% vs. 33.7%, x2 =73.77, P＜0.05). The multivariable analysis showed that hypertriglyceridemia, hypertension, family history of diabetes mellitus were risk factors for development of diabetes mellitus in elderly Han population (x2 =44.34, P＜0.05). Conclusions The prevalence rates of diabetes and pre-diabetes are considerably high in the current state. It should be strengthened to prevent and treat diabetes mellitus and pre-diabetes in Urumqi Han population,especially in residents aged over 60 years.
RESUMO
Objective To analyse the relationship between Calpain10 gene UCSNP43 and UCSNP44 poly morphisms and diabetes in familial type 2 diabetes mellitus of Uygur in Xinjiang.Methods Sixty-two Uygur type 2 diabetic families were enrolled.The polymorphisms of Calpain10 gene UCSNP43 and UCSNP44 were measured by SNP-stream of gene chip.Results (1) The heritability of the first degree relative and the second degree relative in Uygur familial type 2 diabetes were 0.578 and 0.032.(2)There was no difference between UCSNP43 and UCSNP44 polymorphisms of the first and second degree relatives in familial type 2 diabetes mellitus.(3)The carriers of USCNP43 AA genotype had higher body mass index and fasting insulin than GG and GA genotypes carriers.Conclu sion With the downgrading of the familial relationship,the heritability of type 2 diabetes mellitus was decreasing. The carriers of UCSNP43 AA genotype might have higher insulin resistance than those with GG and AG genotypes.
RESUMO
Objective To study the difference between the metabolic syndrome(MS)diagnosis made with International Diabetes Federation(IDF)worldwide definition and the Adult Treatment Panel Ⅲ (ATPⅢ)of National Cholesterol Education Program(NCEP).Methods Cross-sectional study and descriptive study were used.Results There were 1328 MS patients diagnosed with IDF and 1527 MS patients diagnosed with ATPⅢ.There were 199 MS patients diagnosed with ATPⅢbut not with IDF and these MS patients all had 3-4 risk factors.According to the abnormality of glucose.blood pressure and lipid regulation stated in ATPⅢ criteria.759 more patients were diagnosed as MS than with IDF criteria.Conclusions MS diagnosed with ATP Ⅲ criteria iS more objective than with IDF criteria and ATPⅢ criteria has more space for further theoretical study.
RESUMO
Objective To Study the correlation factors for diabetes pathogenesis of Uygur Nationality in Urumuqi.Methods A cluster sampling was done in 1002 Uygur people aged 25 to 74 years in a part of working units and living area in Urumuqi.All the people received 75g oral glucose tolerance test.Waist and hip circumference,blood pressure,height and body weight were measured.A questionnaire involved in the family history,diet,physical activity and the expenditure on diet was taken.Results(1)63% of the people was male,while 37% was female in our study.The constituent ratio of age was as following:25y～,23.08%;35y～,36.90%;45y～,19.64%;55y～,14.86%and 65y～,5.51%.(2)The prevalence of DM in the study was 14.69%,the abnormality of glucose metabolism was 29.89%.(3)The correlation factors of diabetes were family history of diabetes(OR 0.59),age(OR 0.83),high blood pressure(OR 0.912),waist-to-hip ratio(OR 3.851)and financial spending on diet(OR 5.279) in logistic regression analysis.Conclusions Diabetes-correlated factors are high financial spending on food especially meat products and little cellulose intake,high waist-to-hip ratio.To decrease the prevalence rate of diabetes in Uygur nationality,it is most important to change the diet habit and decrease intra-abdominal fat deposition
RESUMO
BACKGROUND: In China, diabetic patients suffer from various chronic complications with a higher prevalence, which is nearly close to that in developed countries. Especially in Xinjiang, the prevalence is much higher than the average level, and the level of disease control is very poor as a whole.OBJECTIVE: To study the actuality of controlling type 2 diabetes mellitus in Xinjiang so as to analyze its relationship with disease courses.DESIGN: Cluster sampling and stratified analysis.SETTING: Department of Endocrinology, Xinjiang General Hospital of Chinese People's Armed Police Forces.PARTICIPANTS: The survey was conducted at ten treatment centers of Xinjiang(the First Affiliated Hospital of Xinjiang MedicalUniversity, People's Hospital of Xinjiang Uigur Autonomous Region, Urumchi Hospital of Air Force of Chinese PLA, Railway Hospital of Xinjing Uigur Autonomous Region, Military Unit Hospital of Xinjiang, Kuitun Central Hospital of Yili Region of Xinjiang, Kelamay People's Hospital of Xinjiang, Kuler People's Hospital of Xinjiang, the First Division Hospital of Xinjiang Military Unit for Produce and Building, Xinjiang Hospital of Traditional Chinese Medicine). Totally 646 type 2 diabetic patients who had received treatment for diabetes mellitus for 12 months, at any of the centers were randomly recruited with cluster sampling method including 337 males and 309 females. According to different courses of disease, the subjects were divided into 6 groups: 202 cases in group of ＜ 3 years, 89 in group of 3-4 years,89 in group of 5-6 years, 77 in group of 7-9 years, 108 in group of 10-14years, and 81 in group of ≥ 15 years. All the subjects agreed to participate in the survey.METHODS: Patients detected their blood sugar level and urine sugar level themselves with portable diabetograph and test paper. For them, there were at least four days per week to take diabetic diet which was considered as common diet control, and there were at least three days per week to participate in leisure activity and at least half an hour per day to spend in proper exercise which was considered as frequent exercise. Complications of diabetes mellitus were diagnosed with clinical manifestation, disease history and objective examination. The survey was performed through letter,telephone counseling, and patient's reexamination. Enumeration data was analyzed with chi-square test.MAIN OUTCOME MEASURES: Differences in blood sugar, urine sugar, management of living style, prevalence of complications in all the diabetic patients with different courses of disease.RESULTS: There were 645, 645, 643, 646 patients with complete data of blood sugar and urine sugar determined periodically at home, participated in the observation of the management of living style, prevalence of diabetic complications and treatment for diabetes mellitus, respectively. ①There was no significant difference in blood sugar and urine sugar level deter mined at home every month among patients of different courses (P ＞ 0.05). ② There was no difference in diet control and exercise among patients of different courses (P ＞ 0.05). ③In patients with disease course of ＜ 15 years, prevalence of the complication in large vessels and extremity,retinopathy, and positive expression of proteinuria presented an increased tendency; whereas, a decreased tendency was found in patients with the disease course of ≥ 15 years(χ2=34.16,60.64,49.18,P=0.00). ④The proportion of applied therapies, such as diet control and exercise, oral antidiabetic drug, insulin, and insulin plus oral anti-diabetic drug, was different in patients with different disease courses (χ2=97.88 ,P=0.00). In patients with short disease courses, diet control or oral anti-diabetic drug was administrated more usually; in those with long disease courses, insulin treatment or insulin plus oral anti-diabetic drug was applied more frequently.CONCLUSION: ①Whether patients determine their blood sugar and urine sugar levels by themselves is not correlated with patients' disease courses. ②Diet control and exercise are not in correlation with disease courses. ③ For patients with the disease course of less than 15 years, the proportion of prevalence of various diabetic complications is increased with the increase of disease courses; for those with the disease course of more than 15 years, however, it is decreased significantly. ④Simple diet control or oral anti-diabetic drug is often applied in patients with short disease courses while insulin or insulin plus oral anti-diabetic drug are administrated in most patients with long disease courses.
