Objective To understand the prevalence of overweight and obesity and its influence factors in Zhuhai inhabitants. Methods Applying multi-stage cluster random sampling in the three administrative areas of Zhuhai including Xiangzhou, Doumen and Jinwan, A questionnaire-based survey was performed in conjunction of the measurement of height and weight among 961 inhabitants aged 15-69 years. In addition, a multivariate unconditional logistic regression model was employed to analyze the influence factors of overweight and obesity. Results The prevalence and standardized rates of overweight and obesity in the study population were 18.1%, 17.6%, 6.6%, 6.5%, respectively. The standardized rates of overweight and obesity in male and female were 18.4%, 5.8%, 16.5%, 7.2%, respectively. Age, drinking, smoking and regional difference were identified as the 4 risk factors of overweight and obesity, their OR values being 1.028, 1.683, 0.677, 1.404, Plt;0.05, respectively. Conclusion The prevalence of overweight and obesity in Zhuhai’s inhabitants was over the average level of Chinese residents, and overweight and obesity has become a major risk factor influencing the health of Zhuhai’s inhabitants. In view of the influence factors of overweight and obesity, timely and effective prevention and control measures should be taken.
ObjectiveTo investigate the prevalence and risk factors of hypertension in urban and rural residents in Chengdu. MethodsA cluster random sampling survey was carried out from February to October in 2010. A total of 2 011 residents aged 35-70 years in four communities of Chengdu (two communities in urban area, two in rural area) were investigated for the incidence of hypertension. Analysis was performed using SPSS 18.0 software. ResultsThe standardized prevalence of hypertension was 31.30% among residents aged 35-70 years, which was much higher in urban than that in rural:39.03% vs. 24.90% (P < 0.05). The results of multivariate logistic regression analysis showed that, age, waist, heart rate, fasting blood glucose and education level were the major risk factors of hypertension for male; while age, waist, heart rate, fasting blood glucose, triglyceride and uric acid were the major risk factors for female. ConclusionThe prevalence of hypertension in urban is higher than that in rural in Chengdu. Prevention and intervention should be performed more for whom have increased waist circumfluence, abnormal levels of fasting glucose, and increased heart rate.
ObjectiveIn order to provide guidance for early interference of diabetic retinopathy (DR) in patients with diabetes mellitus (DM), we surveyed the prevalence and analysis the related factors of DR in Shanghai Songnan community. MethodsBased on an established resident health database, an epidemiology study was performed on the residents with DM in Shanghai Songnan community.1177 patients completed questionnaire survey, and received physical examination and laboratory tests. The diagnosis and grading of DR were established based on the ocular fundus images acquired by digital non-mydriasis fundus camera. Patients with incomplete questionnaires were excluded. ResultsThere were 1120 DM patients with valid questionnaires. DR was found in 264 (23.57%) patients. The prevalence of mild, moderate, severe non-proliferative DR and proliferative DR was 17.05%, 5.09%, 1.16% and 0.27% respectively. There was significant differences in age, disease course, systolic blood pressure, insulin usage between the DR group and NDR group(t=-2.647, 2.688, 2.204, 2.291;χ2=12.527;P=0.008, 0.007, 0.028, 0.022, 0.000). There was significant differences in fasting blood-glucose and insulin usage between the mild, the moderate and the severe DR group(t=21.964, χ2=14.996;P=0.000, 0.001). Stepwise logistic analysis identified that age, DM course, and insulin usage were the related factors of DR (OR=0.769, 1.239, 1.100, 1.071, 1.682;P=0.001, 0.043, 0.176, 0.097, 0.005). ConclusionThe age, DM course, and insulin usage were the related factors of DR. The high prevalence of DR indicated the importance of the management of diabetic patients.
Objective To investigate the drug resistance and homogeneous analysis of Acinetobacter baumanii in emergency intensive care unit ( EICU) . Methods Four multidrug-resistant Acinetobacter baumannii ( MDR-Ab) strains isolated fromnosocomial inpatients fromJuly 25 to September 7 in 2009 were collected and tested for drug sensitivity and MIC determination as well. The A. baumannii isolates were typed with pulsed-field gel electrophoresis ( PFGE) to determine whether they derived fromthe same clone.Results Four isolates from nosocomial inpatients were resistant to multiple antibiotics including carbapenem. The PFGE types identified from four isolates were A and B. The A. baumannii isolates did not derived from the same clone. Conclusion The prevalence of nosocomial infection is not due to transmission of the same strains among different individuals in EICU.

Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by Stata 12.0 software.ResultsA total of 11 studies involving 13 398 patients were included. The results of meta-analysis showed that, the overall prevalence of SP was 31.0% (95%CI 18.0% to 44.0%). Subgroup analysis showed that the prevalence rate of male was 34.9% (95%CI 18.6% to 88.5%). The prevalence rates of SP among 60, 70, 80 and 90 age groups were 20.0% (95%CI 14.2% to 25.7%), 48.4% (95%CI 21.5% to 75.3%), 53% (95%CI 12.4% to 93.5%), and 58.5% (95%CI 22.4% to 94.6%), respectively. The prevalence rates of SP in community, hospital and cadre relaxation club were 33.4% (95%CI 31.3% to 35.6%), 40.4% (95%CI 22% to 58.7%), and 14.4% (95%CI 1.1% to 27.7%), respectively. The prevalence rates of SP in southern China and northern China were 26.7% (95%CI 18.7% to 34.7%) and 36.8% (95%CI 21.8% to 51.7%), respectively.ConclusionsThe overall prevalence rate of SP in the Chinese population is high. The prevalence rates of SP among ages, regions and research sites are different.
ObjectiveTo know the situation of nosocomial infection in 2014 in a western region hospital, in order to provide a scientific basis for hospital infection control and management. MethodWe selected the patients on August 14th in 2014 during the time from 00:00 to 24:00 as our study subjects. Bedside investigation and medical records investigation were combined to study the cross-sectional survey of nosocomial infection. We completed the questionnaire, and used statistical methods to count related data about nosocomial infections and community-acquired infections. ResultsA total of 1 908 patients were investigated. The nosocomial infection prevalence rate was 4.45%, and the community-acquired infection prevalence rate was 29.09%. The highest prevalence of nosocomial infection department was the Intensive Care Unit (38.10%); the top three surgical systems were Thoracic Surgery (18.67%), General Surgery (16.67%), and Neurosurgery (10.53%), and the top three medical systems were Endocrinology (11.11%), Neurology (6.67%), and Infectious Diseases Department (5.88%). The top three community-acquired infections occurred in Pediatrics Department (non-neonatal group) (95.37%), Burn surgery (92.31%), and Respiratory Medicine (86.46%). The main infection site for both nosocomial and community-acquired infection was lower respiratory tract (58.24%). Pathogens were mainly Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii, Staphylococcus aureus, and Pseudomonas aeruginosa. Hospital and community-acquired infection bacterial spectrum were consistent. And the rate of antibiotics use was 40.82%, in which 126 patients used for prevention (6.60%), and 599 patients used for treatment (31.39%). For patients using the drugs for treatment, bacterial culture submission rate was 80.71%, and the positive rate was 43.78%.

Objective To investigate the prevalence and related factors of diabetic retinopathy (DR) among residents with type 2 diabetes mellitus (T2DM) in Culai Town of Tai'an City in Shandong Province. Methods According to the DM management file database for community, 785 patients with T2DM were randomly selected by cluster sampling method. The questionnaires, routine general examinations, visual and fundus-free fluoroscopy were performed on all the patients. DR diagnosis and classification was according to the guidelines for clinical diagnosis and treatment of DR in China (2014). Both monocular and binocular DR were selected as DR patients, and the worse eye for binocular DR were treated as the DR classification of the patient. The patients were grouped by presence or absence of DR. GraphPad Prism 6, SigmaPlot 12.5, SPSS 20.0 and Excel were used to achieve data analysis. Also, SPSS 20.0 was used for multi-factor logistic regression analysis. Results A total of 699 patients (89.04%) were actually recorded. There were 122 eyes of 63 patients (9.01%) with DR (DR group), 1272 eyes of 636 patients (90.99%) without DR (NDR group). Among the 122 eyes of DR, there were 19 (15.57%), 17 (13.93%), 70 (57.38%), 10 (8.20%), 6 (4.92%) eyes in stage Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ, respectively. The differences of mean age (t=15 290, P=0.002), DM duration (t=9075, P＜0.000) and diastolic blood pressure (t=15 810, P=0.006) between the two groups were statistically significant. There were 23 (36.51%) and 394 (61.95%) patients with hypertension history in the DR group and the NDR group, with the significant difference ( χ2=15.42, OR=0.35, 95%CI 0.21-0.60). There were 57 (90.48%) and 500 (78.62%) patients with fasting blood glucose larger than 6.11 mmol/L in the DR group and the NDR group, with the significant difference (OR=2.51, 95%CI 1.06-5.95, P=0.031). Logistic regression analysis showed that the age, fasting blood glucose and DM duration were influencing factors for DR (OR=1.039, 0.864, 0.898; P=0.021, ＜0.000, ＜0.000). Conclusion The prevalence of DR in patients with T2DM in Culai Town of Tai'an City is 9.01%. Age, DM duration, fasting blood glucose are associated to DR. Those with a history of hypertension may have a lower risk of DR than those without a history of hypertension.
ObjectiveTo learn the current situation and feature of nosocomial infection (NI), so as to provide reference for making the prevention measures.

Intensive Care Unit had the highest NI prevalence (28.57%), followed by Hematology Department (20.00%) and Neurosurgery Department (20.00%). Lower respiratory tract (38.46%) was the main infection site, followed by superficial surgical incision (13.85%). The usage rate of antimicrobial agents was 30.56%, and 40 strains of pathogens were isolated, in which Klebsiella pneumonia (15.0%), Pseudomonas aeruginosa (12.5%) and Escherichia coli (10.0%) were the main ones. ConclusionTarget monitoring management of key departments and key sites should be strengthened, and the management of antimicrobial agents should be stressed and invasive procedures should be decreased.
Objective To understand the current rate of nosocomial infection and its changing trend in a grade A comprehensive hospital in 10 years, and to provide scientific basis for the monitoring, control and management of nosocomial infection. Methods Using the method of cross-sectional survey, the inpatients in Mianyang Central Hospital from 2011 to 2020 were selected for bedside survey, and the questionnaire was filled in after review of medical records. The data of cross-sectional survey of nosocomial infection were collected, and the infection-related data of nosocomial and community-acquired infection of patients in each department were statistically analyzed. Results A total of 19 595 cases were investigated. The prevalence rate of nosocomial infection was 3.79%, and the the case prevalence rate of nosocomial infection was 4.04%. The prevalence of community-acquired infection was 33.44%, and the case prevalence rate of community-acquired infection was 35.30%. The departments with higher prevalence rate in nosocomial infection were intensive care unit, neurosurgery, cardiothoracic surgery and hematology. The departments with high prevalence rate in the community-acquired infection were burn department, pediatrics department, neonatology department, respiratory medicine department and pediatric intensive care unit. The most common site of nosocomial infection was lower respiratory tract infection, followed by upper respiratory tract sensation, urinary tract, abdominal tissue and blood. The main pathogens of nosocomial infections were Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii, Staphylococcus aureus, and Pseudomonas aeruginosa. The utilization rate of antibacterial drugs was 42.93%. There was a downward trend in prophylactic drug use, mainly one drug combination, and the proportion of combination drug decreased.Conclusion Through the investigation, it can be seen that the key points of nosocomial infection management and prevention and control should be lower respiratory tract infection, postoperative surgical infection, multi-drug resistant bacteria management and rational use of antibiotics.
