Objective To compare the application of three diagnostic criteria for metabolic syndrome(MS) among the elderly in community. Methods 773 elderly people in the community were diagnosed for MS by the Chinese Medical Association Diabetes Society (CDS),International Diabetes Federation (IDF) and revised National Cholesterol Education Prongram-Adult Treatment Panel(ATP Ⅲ* ) criteria,respectively.The diagnosis accordance rates were compared among the different diagnostic criteria. Results The MS prevalence rates in the elderly were 32.5％ (251/773),53.4％ (413/773) and 47.2％ (365/773) according to CDS,IDF and ATP Ⅲ* criteria,respectively and there were significant difference among the criteria (Q=173.10,P＜0.01 ).The MS prevalence was higher in women than in men especially by IDF [57.3％ (284/487)vs.45.1％ (129/286),x2=12.64,P＜0.01]and ATPⅢ* criteria [53.0％(258/487)vs. 37.4％ (107/286),x2=17.52,P＜0.01].The coincidences in the diagnosis of MS were 88.6％ (Kappa=0.773,P＜0.01)using IDF and ATPⅢ * definitions,75.7％ using CDS and ATPⅢ *,and 73.7％ using CDS and IDF.Conclusions The agreement in the diagnosis of MS using IDF and ATPⅢ* definitions is higher than using CDS and IDF or ATPⅢ * definitions.

Objective To investigate the effect of hypertriglyceridemic waist(HTWC)phenotype on cognitive function in patients with type 2 diabetes.Methods According to the standard of plasma triglycerides concentration≥1.7 mmoL/L,waist circumference(WC)≥ 90 cm in men or ≥80 cm in women,304 patients with type 2 diabetes were divided into four groups:normal triglycerides and waist circumference group(group A,n =65),normal waist circumference and hypertriglyceridemia group (group B,n=53),abdominal obesity and normal triglycerides group(group C,n=114),and HTWC group(group D,n =72)for prospective studies.Patients in four groups were surveyed with Mini-mental state examination (MMSE)and Montreal cognitive assessment (MOCA).And changes of cognitive function among the four groups were compared.Results Total score for the MMSE was significantly lower in group D than in group A(27.1±1.9 vs.29.0±1.3,F=2.869,P=0.019).The subscales of attention and calculation(4.0± 1.4 vs.4.6±0.9,F=1.605,P=0.047)and recall(2.2± 0.9 vs.2.6±0.6,F=1.959,P=0.043) were significantly lower in group D than in group A.Total score for the MOCA was significantly lower in group D than in group A(23.4±3.9 vs.25.9±3.6,F =1.975,P=0.031).The subscales of visuospatial and executive(3.5 ± 1.4 vs.4.1 ± 0.9,F=1.537,P =0.048),attention(5.1±1.4 vs.5.7±0.9,F=1.660,P=0.048)and orientation(5.6±1.0 vs.6.0± 0.0,F=2.362,P=0.030)were significantly lower in group D than in group A.Conclusions There is a statistically more significant decline in cognitive function in patients with HTWC phenotype and the effective intervention and treatment are needed.

Objective To study the effects of type 2 diabetes (T2DM) with hypertension on cognitive function in those community-based elderly who were aged 60 and over,in Beijing.Methods 82 patients with T2DM,142 patients with both T2DM and hypertension and 277 normal controls were investigated in this study.Both methods as:the Montreal Cognitive Assessment (MoCA) and Mini-Mental Status Examination (MMSE) were used to determine cognitive change.Results The total MMSE scores showed significant decrease between T2DM with hypertension and controls [(28.42± 1.52) vs.(28.88± 1.47),P＜0.05].The MoCA score of the total scores [(25.20± 3.91) vs.(26.50 ± 3.29),P＜0.05],sub-scores of visuospatial,executive [(3.60± 1.56) vs.(3.96± 1.18),P＜0.05] and language [(2.10± 0.80) vs.(2.37± 0.80),P＜0.05] significantly decreased in T2DM patients with hypertension and in the normal controls.Data from the Multiple logistic regression analysis showed that older age and less education were risk factors for cognitive impairment.Conclusion T2DM and hypertension damaged the cognitive function of patients.

BACKGROUND: With social development, the average life span is prolonged. The issue of aging has increasingly attracted people's attention. It is necessary to promote the health status and the guality of life of the elderly..OBJECTIVE: To understand the status and distribution features of several common diseases which influence the quality of life of elderly.DESIGN: Random cluster sampling methods and a cross-section survey.SETTING: Beijing Institute of Geriatrics of Beijing Hospital.PARTICIPANTS:Totally 1 558 old people aged ≥60 years living in 10 communities affiliated to Jianguomen district office of the Eastern District of Beijing City,and 8 villages affiliated to Xiangyang and Henan Villagers'Commissions of Shunyi County of Beijing from May 1997 and October 1997 were recruited.In fact,1 434 persons responded,with a response rate being 92％,319 males and 498 females came from the city;242 males and 375 females came from the villages.METHODS:Questionnaires were filled up,and physical examinations were conducted in all the elderly. MAIN OUTCOME MEASURES: The 6 common diseases were observed among the elderly: Hyperplasia of prostate, abnormal audition, cartaract ,osteoarthritis, fracture and constipation.RESULTS:Totally 1434 elderly entered the stage of result analysis.①The incidence of hyperplasia of prostate in the males from the urban areas was lower than that in the rural areas (61.4％,65.7％, P ＜ 0.01 ). ② The incidence of abnormal audition among the elderly from the urban areas was lower than that in the rural areas (53.9％,64.7％,P ＜ 0.01).③ The incidence of cataract of the two eyes in the elderly from the urban areas was higher than that in the rural areas(46.4％,44.4％, P ＜ 0.01). ④ The incidence of osteoarthropathy in the elderly from the urban areas was higher than that in the rural areas (24.4％,14.9, P ＜ 0.01). ⑤ The incidence of fracture in the elderly from the urban areas was higher than that in the rural areas (14.2％,9.1％, P ＜ 0.05). ⑥ The incidence of constipation of the elderly in urban areas was lower than that in the rural areas(18.2％,23.0％,P ＜ 0.05).CONCLUSION:There is a difference between the elderly from the urban areas and the rural areas in hyperplasis of prostate,abnormal audition, cataract, osteoarthropathy, fracture and constipation, and this is related with the economy, nutrition, medical conditions and cultural traits.Therefore, attention should be attached to nutrition and health knowledge of the elderly and prevention and treatment of common diseases among the elderly people.
