Objective To compare the diagnostic criteria of metabolic syndrome(MS) developed by the International Diabetes Federation(IDF) in 2005,the 3th Report of National Cholesterol Education Program-Adult Treatment Panel Ⅲ(NCEP-ATP Ⅲ) in 2005,and the Chinese Diabetes Society(CDS) in 2004.Methors A total of 1039 adults aged 23 to 62 year-old were enrolled in this epidemiological investigation to assess the prevalence of MS by above three definitions.Results The MS prevalence rate was 14.8%,14.2% and 10.7% in ATPⅢ,IDF,and CDS,respectively.The diagnoses agreement of IDF with ATPⅢ was stronger(Kappa=0.912) than IDF with CDS(Kappa=0.466) and ATPⅢ with CDS (Kappa=0.504).CDS definition found 5.7% of non-MS individuals had risk factor accumulation.Those defined by ATPⅢ and IDF criteria were presented with central obesity + ypertriglyceridemia + abnormal blood pressure and central obesity + hypertriglyceridemia + low hish-density lipoprotein hyperlipidemia.However,those defined by CDS criterion were commonly presented with obesity + hypertriglyceridemia + abnormal blood pressure or obesity + hypertriglyceridemia + hyperglycemia.Conclusions The agreement of IDF and ATPⅢ definition was relatively stronger.For better screening sensitivity,those three criteria,or CDS and IDF criteria,or CDS and ATPⅢ criteria should be used together.

Objective To explore the relationship between sleep disorder and management strategies in the elderly patients with primary hypertension.Methods The sleep status of 122 elderly patients with primary hypertension was evaluated by Pittsburgh Sleep Quality Index(PSQI) and Coping Style Questionnaire(CSQ).Results The mean score of PSQI was 8.34±3.81,and 63.93% (78/122) of the participants experienced sleep disorder.The most commonly used management strategy wag "problem-solving" (0.74±0.18) and "rationalization" (0.56±0.19).The management strategies were different by gender and age.The lowest score was found in the "ask-for-help" group(t=2.326,P=0.022),which was negatively related with sleep disorders (r=-0.208,P=0.022).Conclusions Intervention of management strategy in elderly patients with primary hypertension may help to improve their sleep quality.

Objective To investigate the effect of physician guidance on cigarette cessation in current smokers with chronic obstructive pulmonary disease(COPD).Methods Cigarette cessation education and routine telephone follow-up was provided for 70 COPD patients.Pulmonary function and exhaled carbon monoxide level were detected every 3 months.Results After 6 months' follow-up,28 participants(40.00%) successfully quitted cigarette smoking.Seventeen subjects (24.28%) experienced relapse,with mean cessation time(3.08±0.33) months.Once receiving physician guidance,5 re-attempted to quit cigarette smoking,and 12 reduced tobacco consumption. Sixteen subjects(22.86%) did not quit smoking,although the mean cigarette consumption per day was decreased by 60%.Nine participants (12.86%) showed no change in smoking habit. Conclusion Physician guidance could impreve the rate of cigarette cessation in COPD patients.Intensive intervention may be correlated with successful smoking cessation.

Objective To study the effect of body weight management on community residents with over-weight or obesity.Methods Chronic Disease Management Information System was used to establish personal health profile for 10 560 individuals with over-weight or obesity(4660 men and 5900 women,average age 58±12 years).Guide for individualized food intake,physical activity were given to these participants for an average of 9±6 months (range,1 to 32 months) with a following up.The change of body weight before and after the intervention was nalyzed.Statistical software(SPSS 12.0) wag used for the data analysis,the frequencies,rate and trend were analysised by the chi-square test,the means in quatitaitve data was analyzed by the paired t-test.P valuse for statistiacal significance is set for 0.05.Results A total of 9848 participants showed no change in body weight,although weight decrease or increase was seen in 499 and 213,respectively.Before and after the intervention,the proportion of weight remained,decrease or increase among over-weisht + central obesity individuals was 92.3%(6290/6817),5.9%(403/6817) and 1.8% (124/6817);95.5%(2888/3024),2.8%(84/3024) and 1.7%(52/3024) among the simple overweight or obesity group;and 93.2%(670/719),1.7%(12/719)and 5.1%(37/719) among the simple central obesity group,separately.Conclusions Body-weight management among central obesity individuals with over weight in communities is a more effective way of in terms of individule intervention than those individuals only with single over-weight,obesity or central obesity status.

Objective To investigate the correlation of anthropometric parameters with alanine aminotransferase (ALT) in Qinhuangdao college students.Methods A total of 789 subjects from two colleges in Qinhuangdao City (369 men and 420 women) were recruited using a cluster-stratified sampling method.Anthropometric measurements included height,body weight,waist circumference,hip circumference,blood pressure.and ALT.Body mass index,waist to height ratio,and waist to hip ratio were calculated.Results Elevated ALT was found in 16.3% of male participants and 4.0% of females(P<0.05).For males,those with elevated ALT showed significantly higher levels of anthropometric parameters (P<0.05).In females,the levels of anthropometric parameters were similar between subjects with or without elevated ALT(P>0.05).Receiver operating characteristie curve analysis also showed that obesity indices predicted elevated ALT only in men [area under the curve:0.8-0.9(P<0.05) in men,0.5-0.6(P>0.05) in wonlen].Blood pressure did not predict elevated ALT in both men and women (area under the curve:0.5-0.7).Conclusion Dender difference of obesity indices could be found in Qinhuangdao college students.Obesity indices may be independent predictors of elevated ALT in men.However,blood pressure seems not to be an independent predictor of elevated ALT.

Objective To evaluate the effective of weight loss on blood glucose,lipid profile,and blood pressure in over-weight or obesity patients combined with impaired glucose tolerance(IGT).Methods Body weight of 91 over-weight or obesity IGT patients were managed by doctors and nurses.Body weight,waist circumference,blood glucose,lipid profile,blood pressure and liver function of the patients were compared at 3 months with baseline.Results After 3 months' intervention,the levels of body weight,waist circumference,fasting plasma glucose,postprandial glucose,systolic blood pressure,diastolic blood pressure,and glutamie oxalacetie transaminase (COT),instead of triglyeeride and hish-density lipoprotein cholesterol (HDL-C),were significantly reduced.Over weight or obesity IGT patients saw a 1.8 and 2.3 kg body weight loss,respectively.Decreased plasma glucose and blood pressure were found both in the over-weight group and in the obesity groups,but decreased waist circumference and GOT were found only in the over-weight patients.Conclusions Body-weight control may improve the blood glucose,blood pressure,central obesity,or fatty liver in over weight or obesity IGT patients.For those obesity patients,longer and stronger body weight control should be needed.

Objective To explore the relationship between body composition and arterial function index,especially augmentation index(AI),and make clear the impacts of gender and age on the relationship.Methotis A total of 3859 health adults were enrolled in this study.Boay composition was measured by bioelectrical impedance,and AI and pulse wave velocity(PWV) were viewed as indictors for arterial function.Correlation analysis and liner regression analysis were used for data comparison.Results Both body mass index(BMI) and body fat rate positively changed with PWV(r=0.114,both P<0.01).However,BMI showed no relation to AI(r=0.022,P>0.05).Body fat rate was positively and independently associated with AI(r=0.263, P<0.01),which was gender-dependent(female:r=0.219,P<0.01;male:r=0.033,P>0.05).When age was concerned,above relationship was more stronger in participants ≤50 years(β=0.479 vs β=0.321,P<0.01).Conclusion Body fat mass may be a predicting factor of changes in AI.Gender and age could affect the relationship between body fat and rtery function.

Objective To study the relationship between pedometer-based daily physical activity and obesity measurements in adult male leaders living in countryside.Methods A total of 136 men who received routine health screening were measured for body weight,body mass index (BMI),waist circumstance,and total body fat.Daily walking activities were determined by pedometer for 7 days.Results Ⅰ to Ⅱ grade walking activities was found in 58% participants.Daily physical activities were negatively correlated with body weight,waist circumference,BMI and total body fat.Body weight,waist circumference,BMI and total body fat were almost normal when walking activities increased to Ⅲ grade.Only 7% of the subjects participated in exercises.Conclusion Pedometer-based daily physical activities may be significantly correlated with obesity arameters.Increased walking activities will help to loss weight.

Objective To discuss the effects of the health card-based services on community chronic disease management and the utility of community healthcare resources. Methods Follow-up investigation on utilization and satisfaction of card-based health services and coverage of chronic illness management was conducted among cardholder living at Dongcheng District of Beijing during July 1,2006 and December 31,2008. Results The rates of attendance and health education increased from 47.20% or 1.16% to 90.90% and 46.38% ,respectively. The coverage of high blood pressure management and standard hypertension management increased from 47.16% or 45.66% to 80.39% and 78.27%, respectively. The satisfaction of cardholder residents with community healthcare services was improved year by year. Conclusions The health card service pattern plays a significant role in improving chronic disease management,which results in more satisfaction with and utilization of healthcare resources in community.

Objective To study the prevalence of hypertension in She Chinese population of Fujian province and its epidemiological characteristics. Methods Using random sampling method to take advantage of number table, we select a sample of 5350 people who were conducted a questionnaire survey and measured weight, height, blood pressure and other indicators. Results The prevalence of hypertension in She Chinese population of Fujian province was 36. 09%, including undiagnosed number of 1374 cases. The main risk factors of hypertension were age,the level of education, BMI,saltintake. Smoking was not significant with hypertension. The prevalence rate of hypertension among people over 60 years was 63.10%, people comsumed above 8 grams of salt per day had higher pervalence than that in the goup which comsumed below 6 grams or between 6 grams to 8 grams of salt per day. Conclusions The prevalence of hypertension in She had grown rapidly. The She Chinese population should change their lifestyle and hypertension education should perform in this population.
