ABSTRACT
Objective:To investigate the association between serum trace elements and dyslipidemia in Pudong New Area. Methods:A community-based cross-sectional study was carried out. A stratified， cluster sampling approach was used for sampling. In total 1 814 community residents aged above 35 years old were recruited in Pudong New Area， Shanghai. A face-to-face investigation was conducted and blood samples were collected. Serum levels of 16 trace elements， including boron， vanadium， chromium， manganese， iron， cobalt， nickel， copper， zinc， arsenic， selenium， strontium， molybdenum， tin， antimony， and barium were measured by inductively coupled plasma mass spectrometry （ICP-MS）. The relationship between serum trace elements and dyslipidemia was analyzed with single and multiple Logistic regression models. Results:Prevalence of dyslipidemia is higher among participants of more than 45 years old with high BMI， hypertension or diabetes．Serum iron leveled the highest， followed by copper， zinc， selenium， strontium， boron and other trace elements. After adjusting for potential confounders， the odds ratios of dyslipidemia associated with the highest quartile of trace elements concentrations were 1.41 （95%CI： 1.12-1.78）， 0.77 （95%CI： 0.61-0.96）， 1.65 （95%CI： 1.31-2.09）， 1.27 （95%CI： 1.02-1.58）， and 1.32 （95%CI： 1.06-1.66） for chromium， cobalt， zinc， arsenic， and tin， respectively， compared with that associated with the other three quartiles. Conclusion:Some serum trace elements are potentially associated with dyslipidemia in community residents.
ABSTRACT
Objective:To investigate the association between sleep quality and the risk of acute exacerbation in mild and moderate chronic obstructive pulmonary disease （COPD） patients in Pudong New Area of Shanghai. Methods:This was a prospective study involving eligible mild and moderate COPD patients from 10 communities randomly selected in Pudong New District of Shanghai. A structured questionnaire was used to collect demographic characteristics， clinical information and information on acute exacerbation. Sleep quality was assessed using the Pittsburgh Sleep Quality Index （PSQI） in Chinese. Multiple negative binomial regression was used to estimate the association between sleep quality and risk of exacerbation. Results:Altogether 212 mild/moderate COPD patients participated and completed the entire survey， of whom the majority （95.8%） were mild COPD patients， 110 persons female and over half （54.2%） over 65 years old. 32.9% of the patients had poorer sleep quality at baseline. 18.9% of the patients reported exacerbation over the past year during follow-ups. Multiple negative binomial regression suggested that increased PSQI was related to higher risk of exacerbation （RRad=1.12， 95%CI：1.02-1.24）， and patients with poorer sleep efficiency had a higher risk of exacerbation （RRad=1.66， 95%CI：1.17-5.43）. Conclusion:Poorer sleep quality is associated with a higher risk of exacerbation in community mild/moderate COPD patients， especially in those with problem of sleep efficiency. More attention to sleep disorders is warranted in community management or self-management of patients with COPD.
ABSTRACT
Objective To investigate the risk factors for recurrence of cerebral infarction and to propose secondary prevention methods . Methods Data of 628 patients with cerebral infarction from Jan.2012 to Dec.2014 were collected by the community reported network into a cohort study .The prevalence of recurrence and associated risk factors of cerebral infarction were investigated . Results Recurrence rate of cerebral infarction was 9.08%.History of hypertension (OR=4.797, P=0.001), long term of tobacco use ( OR=2 .844 , P=0 .005 ) , abdominal obesity or overweight ( OR=2 .421 , P=0.041) and farming(OR=3.723, P<0.001)were the independent risk factors for recurrence of cerebral infarction. Conclusion The recurrence rate of cerebral infraction is high , which is affected by various factors.
ABSTRACT
Objective To evaluate different hypertension management models in communities and their impact on incidence of cardio-cerebrovascular disease in hypertensive patients. Methods A total of 1 578 hypertension patients in several communities in Pudong New Area were recruited in the study ( August 2008 to December 2012 ) according to the inclusion criteria and randomly divided into two groups.The control group was given routine hypertension management and the study group was given detailed hypertension management, while health commissioners and community physicians were in charge of the follow-up and data collection. Results The incidence of cardio-cerebrovascular disease (1.33%) in study group (1.33%) was significantly lower than that of the control group (4.22%) ( P <0.05). Multivariate logistic regression analysis showed that age, male, course-of-disease, patients with hypertension family history, increase in SCr and LDL-C increased the risk for getting ardio-cerebrovascular disease (P <0.05).The risk of study group was 0.348 times the control group ( P <0.05). Conclusion Compared with control group, detailed hypertension management model conducted in study group has the advantages that effectively reduced the rate of cardio-cerebrovascular disease.
ABSTRACT
Objective To investigate epidemic characteristics and risk factors of hypertension among residents aged above 15 years in Pudong New Area of Shanghai. Methods We selected the subjects through a multistage stratified cluster sampling procedure; all thirty towns of Pudong New Area were stratified into three levels according to their economic status and 10 657 people selected as survey subjcets from each economic level.A questionnaire survey was conducted in conjunction with measurements of body height and weight, fasting plasma glucose, 2-hour postprandial blood glucose, blood lipid and blood pressure among 10 657 inhabitants aged above 15 years.Multivariate unconditional regression model was employed to analyze the influence factors of hypertension. Results The crude prevalence rate of hypertension in the residents was 41.3%.The prevalence rates of male was high than female (P<0.001). With the increment of age, the hypertension prevalence rate of all residents were obviously elevated.The residents with lower education had a higher hypertension prevalence rate.There was no significant difference in hypertension prevalence between rural and urban.The results of logistic regresssion showed that the risk factors of hypertension were age,gender,educational level,family history of hypertension,central obesity, body mass index, C-reactive protein, 2-hour postprandial blood glucose and urinary albumin/creatinine ratio(P<0.05). Conclusion The results indicated that hypertension was highly prevalent in Pudong New Area.Body mass index ( BMI) and central obesity were related factors for hypertension which were changeable.
