MethodsA survey, including height, weight, blood pressure and pulse, was carried out in a general population of Chengdu. A total of 711 subjects (average age: 63.28±6.25 years; male: 57.8%) were recruited by random sampling method. Results：The proportion of overweight and obesity was about 45%. The hypertension prevalence rate was significantly positively correlated with BMI (Plt;0.01), and that was also seen in the level of SBP and DBP for the female (Plt;0.05). In logistic regression analysis adjusting for age, gender, waist, uric acid, the standardized OR for higher BMI (≥28.0 kg/m2) as a risk factor of hypertension was 5.140. Conclusion：The proportion of overweight and obesity was great in Chengdu area. BMI can affect the prevalence rate of hypertension and the level of blood pressure.
ObjectiveTo systematically review the prevalence of osteoarthritis in Chinese aged 40 and above from January 2000 to December 2019.MethodsPubMed, ScienceDirect, Wiley Online Library, The Cochrane Library, CBM, VIP, CNKI and WanFang Data databases were electronically searched to collect cross-sectional studies on osteoarthritis in Chinese aged 40 and above from January 1st, 2000 to December 31st, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Meta-analysis was then performed using R 3.5.2 software.ResultsA total of 29 cross-sectional studies with a total sample of 60 711 cases and 19 707 patients were included. The results of meta-analysis showed that, the crude prevalence of osteoarthritis in Chinese aged 40 and over was 38.46% (95%CI 24.31% to 46.22%). Subgroup analysis results showed that the prevalence of lumbar osteoarthritis was the highest (24.79%, 95%CI 13.28% to 27.37%), followed by knee osteoarthritis prevalence (20.50%, 95%CI 14.51% to 27.23%) which increased with age. The prevalence of knee osteoarthritis in females (25.14%, 95%CI 19.54% to 31.19%) was higher than that in males (18.99%, 95%CI 13.86% to 24.71%). The prevalence of knee and lumbar osteoarthritis in rural areas was higher than that in urban areas. The prevalence of knee osteoarthritis in western China (23.59%, 95%CI 18.34% to 30.35%) was higher than that in eastern China (18.36%, 95%CI 12.43% to 27.92%) and central China (15.54%, 95%CI 11.22% to 21.53%). The prevalence of lumbar osteoarthritis in western China (31.17%, 95%CI 19.21% to 50.60%) was higher than that in eastern China (24.38%, 95%CI 16.26% to 36.54%). The incidence of cervical osteoarthritis in the eastern China (20.49%, 95%CI 13.90% to 30.21%) was higher than that in the western China (12.32% 95%CI 8.09% to 18.75%). The prevalence of hand osteoarthritis in western China (6.85%, 95%CI 2.71% to 8.13%) was higher than that in eastern China (2.7%, 95%CI 1.33% to 5.48%).ConclusionsCurrent evidence shows that the prevalence of osteoarthritis in Chinese aged 40 and above is high, and the prevalence of lumbar osteoarthritis is the highest, and the prevalence in western China is higher than that in eastern and central China, followed by knee osteoarthritis, in which the prevalence in females, rural areas, and western China is high. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusion.
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.

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.
ObjectivesTo systematically review the prevalence of asthma in adults (>14 years old) in China.MethodsPubMed, Web of Science, CENTRAL, CINAHL, WanFang Data, CBM, CNKI, and VIP databases were electronically searched to collect cross-sectional studies on the prevalence of asthma in Chinese adults from January 2000 to December 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using Stata 15.0 software.ResultsA total of 67 cross-sectional studies, involving 1 381 673 subjects and 19 871 adult asthma patients were included. The results of meta-analysis showed that the prevalence rate of asthma in adults in China was 1.81% (95%CI 1.59% to 2.01%). The subgroup analysis showed that the prevalence rates of asthma in males and females were 1.87% and 1.76%, respectively. The prevalence rates were 2.16% in the northeast region, 1.34% in the central region, 1.63% in the eastern region and 2.23% in the western region. The prevalence rates were 0.73%, 1.53%, and 2.81% in 15-40 years old, 41-60 years old, and >60 years old, respectively. The prevalence rates were 3.07% in illiteracy population, 1.69% in primary school population, 1.46% in junior middle school population, 1.01% in senior high school population and 0.98% in college and above population. The prevalence rates were 2.23%, 2.10%, 1.17%, 1.45%, 1.09%, and 1.41% in agriculture, forestry and animal husbandry personnel, workers, public officials, business and service personnel, military personnel, and other occupations, respectively. The prevalence rates were 1.41% and 1.59% in Han and other ethnic populations, respectively. The prevalence rates were 2.03% in cities and 1.99% in rural areas. And the prevalence rates were 1.22% in 2000 to 2005, 2.07% in 2006 to 2010, 2.25% in 2011 to 2015, and 2.62% in 2016 to 2019.ConclusionsThe prevalence rate of asthma in Chinese adults is higher, which is different due to the influence of age, sex, region, education, and occupation.
Objective To understand the status of needs, demands and utilization of health services of urban and rural residents in Chongqing, so as to provide references for the evaluation of health services status and policy making and regulating. Methods The data from family health questionnaire of health service survey in Western China in 2008 were descriptively analyzed. Results The two-week prevalence rate was 216.9‰ and the two-week hospital visit rate was 211.5‰. The sick people who did not seek medical care accounted for 56.2% among the sick population. The chronic disease prevalence rate was 226.4‰. The annual hospitalization rate was 77.1‰. Conclusion During the past five-year from 2003 to 2008, the needs of health services in Chongqing have had no big change, but the chronic disease prevalence rate has been in uptrend, and the utilization has obviously increased. And the economic factor is still the major cause for impeding residents to seek medical care. So it’s necessary to strengthen the construction of primary health care institutions, to improve the level of health insurance system, and to decrease the disparity in urban and rural areas.
