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.
ObjectiveIn order to improve the prevention and treatment of bronchial asthma, the prevalence and risk factors of asthma in Chengdu among residents over 14 years old were investigated.MethodsA cross-sectional survey was conducted in Chengdu. The inhabitants (age > 14 years) recruited in this household questionnaire survey were through multi-stage cluster random sampling. Univariate and multivariate logistic regression were used to analyze the risk factors of asthma.ResultsA total of 3 477 subjects were finally recruited in this study. Of them, 131 were asthmatic patients; and the prevalence rate was 3.8%. There were significant differences observed in the prevalence of asthma among people of different ages, residences, occupations and educational levels (χ2=191.084, P<0.05; χ2=9.114, P<0.05; χ2=114.268, P<0.05; χ2=62.123, P<0.05). Univariate regression analysis showed that the risk factors of asthma included five factors (measles, chickenpox, pneumonia, tracheobronchitis and intestinal parasitic diseases) related to childhood illness, and two factors (asthma and chronic bronchitis) related to the first-degree relatives (P<0.05). In addition, active smoking history was a risk factor for asthma in men (P<0.05). Multivariate logistic regression indicated that measles, pneumonia, tracheobronchitis, intestinal parasitic diseases in childhood and first-degree relatives suffering from asthma were independent risk factors for asthma.ConclusionsThis study describes the epidemiological characteristics of asthma in Chengdu among adolescents (age>14 years) and adults. The history of measles, pneumonia, tracheobronchitis, and intestinal parasitic diseases in childhood, and first-degree relatives suffering from asthma are the independent risk factors for asthma. In addition, active smoking history is a risk factor for asthma in men.
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.
ObjectiveTo systematically review the prevalence of cognitive impairment in patients with sarcopenia. MethodsThe PubMed, EMbase, Web of Science, Cochrane Library, CBM, CNKI, VIP and WanFang Data databases were electronically searched to collect studies related to the objectives from inception to December 10, 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using Stata 14.0 software. ResultsA total of 27 studies were included. The overall prevalence rate of cognitive impairment in sarcopenia was 36.1% (95%CI 29.4% to 42.8%). Subgroup analysis showed that the prevalence in Europe was higher than that in other areas. The prevalence of nursing home residents was highest. ConclusionCurrent evidence shows that the prevalence of cognitive impairment in patients with sarcopenia is high. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
Objective To analyse the prevalence of hemorrhoids in 1 795 regular healthcheck adults in our hospital, and to investigate the etiologic features and preventive measures. MethodsThe anal examination data of 1 795 regular healthcheck adults werer reviewed and analysed mainly on the clinical features of hemorrhoids. Results All of these adults had long-sitting jobs and did less exercises. The prevalence of hemorrhoids was about 67.02% (1 203/1 795), of which mixed type was predominant (53.37%, 958/1 795) and constituent ratio was 79.63% (958/1 203)， Plt;0.05. The prevalence of hemorrhoids increased with age, especially in adults more than 60 years of age (gt;70%). The females under 30 years of age suffered from hemorrhoids more than the couterpart males 〔61.11% (44/72) vs. 22.50% （9/40)〕, Plt;0.05. There was no significant difference of hemorrhoids in gender whose age was above 30 years (P＞0.05). Conclusions Hemorrhoids, especially mixed types, are prevalent among the people who has a long-sitting and less sports lifestyle. More active preventive measures shall be taken in this group of people.
ObjectivesTo systematically review the prevalence of rosacea in China.MethodsPubMed, The Cochrane Library, EMbase, CNKI, WanFang Data and VIP databases were electronically searched to collect literature of the prevalence of rosacea in China from inception to September 5th, 2018. Two reviewers independently screened literature, extracted data and then meta-analysis was performed by using Stata 12.0 software.ResultsA total of 54 studies were included. The pooled prevalence of rosacea from 44 population-based or community-based studies was 0.27% (95%CI 0.22 to 0.32) and from 10 hospital-based studies was 1.47% (95%CI 1.08 to 1.86). Based on population-based or community-based studies, the highest prevalence was in the early 1980s (2.19%), followed by a gradual decline, to the lowest (0.17%) in the early 1990s, after that the prevalence increased to 1.24% till 2015. Based on hospital-based studies, the prevalence had a maximum of 4.64% in the past decade. The Northwest China and North China had higher prevalence of rosacea (population-based or community-based studies: 1.24% in Northwest China, 1.1% in North China; hospital-based studies: 6.03% in Northwest China, 2.83% in North China). The prevalence in East China and South China was relatively low (population-based or community-based studies: 0.02% in East China and 0.32% in South China; Hospital-based studies: 0.28% in South China). The prevalence of rosacea in female (0.36%) was higher than that of male (0.19%) in population-based or community-based studies.ConclusionsIn China, the pooled prevalence of rosacea is 0.27% in population-based or community-based studies and 1.47% in hospital-based studies. Rosacea is common in North China and Northwest China. Female has higher prevalence than male.
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.
Objective To study the prevalence of snoring in adults aged over 35 yrs in Kelamayi city of Xinjiang province, and screen the snoring associated factors.Methods 2600 subjects( age≥35 yrs) were enrolled from a random sample of the population living in 5 streets, two districts in Kelamayi city. All subjects were required to answer questions about their snoring by himself or bed partner at home. The questionnaire included items concerning snoring, daytime sleepness ( Epworth sleep scale, ESS) , smoking and drinking habits, while height, weight, neck circumference, abdominal circumference, waistline, and hip circumference were meatured. The subjects were assigned to a high risk group and a low risk group according to the questionaire of scoring. Results 2590 subjects had completed the questionnaire and 2513 ( 97. 0% )were eligble for evaluation. The cases of ever snoring was 1312 ( 52. 2% ) , among which moderate to severe snoring accounted for 38. 9% . Before the age of 60 yrs, the risk of snoring increased with age, and higher in males than females( 61. 7% vs. 45. 1% ) . The prevalence of snoring increased with neck circumference( P lt;0. 05) . The body mass index ( BMI) [ ( 28. 2 ±3. 6) kg/m2 vs. ( 25. 1 ±3. 9) kg/m2 ] , neck circumference [ ( 37. 7 ±3. 6) cmvs. ( 35. 6 ±3. 6) cm] , abdominal circumference [ ( 96. 9 ±13. 6) cm vs. ( 88. 7 ±11. 1) cm] , waistline [ ( 92. 2 ±9. 8) cm vs. ( 84. 7 ±10. 2) cm] , hip circumference [ ( 102. 9 ±9. 6) cm vs.( 96. 4 ±9. 3) cm] , proportionlity of waistline to hip circumference ( 0. 90 ±0. 07 vs. 0. 88 ±0. 08) , systolic blood pressure [ ( 132. 0 ±17. 5) mm Hg vs. ( 125. 6 ±16. 8) mm Hg] , and diastolic blood pressure [ ( 83. 3 ±12. 8) mm Hg vs. ( 78. 3 ±12. 6) mm Hg] were significantly different bettween the high and the low risk groups ( P lt; 0. 01) . Logistic regression analysis revealed that age ( OR = 1. 519) , BMI ( OR =2. 549) , neck circumference (OR = 2. 473) , smoking (OR = 2. 765) , ESS(OR = 2. 575) , and postmenopause( OR=1. 806) were main risk factors for snoring( P lt; 0. 05) . Conclusions The prevalence of snoring in adults over 35 yrs is high in Kelamayi city. The high risk factors for snoring are age, BMI, neck circumference, smoking, ESS, and post-menopause.
ObjectiveTo investigate the prevalence rate of nosocomial infection in West China Hospital of Sichuan University and to analyze the implementation effect of nosocomial infection control measures, so as to provide reference for infection control.MethodsAn investigation of the prevalence rate of nosocomial infections was performed on patients who were admitted in West China Hospital of Sichuan University from 0:00-24:00 on a day of every late June from 2012 to 2018 by using bedside investigation in combination with inpatient medical record query, and the data was verified, summarized, and statistically analyzed by the professionals of Nosocomial Infection Management Department.ResultsFrom 2012 to 2018, the prevalence rates of nosocomial infections were 5.19%, 4.20%, 3.94%, 4.26%, 4.29%, 4.25%, and 2.97% in West China Hospital of Sichuan University, which tended to decline (χ2=32.826, P<0.001). There was no significant difference in annual total infection rate in the Department of Internal Medicine, however, the infection rate in the Department of Hematology tended to decline (χ2=6.127, P<0.05); in the Department of Surgical Medicine, the total infection rate tended to decline(χ2=18.721, P<0.001); in particular, the infection rate in the Department of Thoracic Surgery tended to decline(χ2=3.906, P<0.05); the annual difference in infection rate in the Intensive Care Unit (ICU) was not statistically significant. The key site of nosocomial infection was dominated by the lower respiratory tract, and the annual difference was not statistically significant. In particular, postoperative pneumonia has increased since 2014 (χ2=9.56, P=0.002). The nosocomial pathogens which had the highest constituent ratio over the years were Acinetobacter baumannii (in 2012, 2013, 2014, 2017, and 2018), Klebsiella pneumonia (in 2015), and Escherichia coli (in 2016). The annual difference in rate of antimicrobial use was not statistically significant(χ2=3.75, P=0.053), while the rate of antimicrobial use in the ICU tended to decline (χ2=30.42, P=0.000).ConclusionsThe prevalence rate of nosocomial infection in West China Hospital of Sichuan University tends to decline. However, sufficient attention still requires to be paid to lower respiratory tract infection, particularly for patients with postoperative pneumonia.
