Objective To investigate the prevalence of hyperuricemia and the current status as well as differences of cardiovascular risk factors in hyperuricemia patients between urban and rural areas in Chengdu. Methods We randomly sampled 2 032 patients aged from 35 to 70 years age in urban and rural communities, using a questionnaire, physical examination and laboratory tests. Results a) The prevalence of hyperuricemia was 17.77%, which was higher in urban residents (21.38%) than that in rural residents (14.16%). b) The prevalence of hyperuricemia associated with hypercholesterolemia was higher in urban residents (34.10%) than that in rural residents (13.98%); urban women (39.06%) were higher than rural women (16.13%) and urban men (26.97%) were higher than rural men (12.20%). c) The prevalence of hyperuricemia associated with hypertension which was higher in urban residents (58.06%) than that in rural residents (32.64%); urban women (59.38%) were higher than rural women (35.48%) and urban men (56.18%) were higher than rural men (30.49%). d) The prevalence of hyperuricemia associated with impaired glucose tolerance (IGT) in urban women (28.91%) were lower than that in rural women (45.16%). Conclusion Hypercholesterolemia and hypertension are the most commonly seen cardiovascular risk factors accompanied in patients with hyperuricemia in urban areas, which has obviously higher prevalence than in rural areas. IGT is the most commonly seen cardiovascular risk factors accompanied in patients with hyperuricemia among rural women. But in aspects of hyperuricemia associated with impaired fasting glucose (IFG), hypertriglyceridemia, low high-density fetoprotein cholesterol, abdominal obesity and obesity, there is no difference between urban and rural areas.

Objective To provide baseline data for the Special Healthcare Program of Comprehensive Reform for Coordinated and Balanced Urban-rural Development in Chengdu. Methods We selected 7 township/community health institutions and 6 village health posts /street clinics using stratified sampling to take account of the levels of economic development and the distance from the centre of Chengdu We then performed on-site surveys and secondary research. Data were analyzed by using Epidata or Excel. Results The utilization of health institutions was generally good. The number of visits and number of inpatients in medical institutions increased steadily. The utilization rate of hospital beds and doctors’ workload were higher than the national average. The average medical expense per outpatient /inpatient was far lower than the national level. The overall condition of the health institutions that close to the centre of Chengdu was better. Conclusion We should persist in taking advantage of the rural hospitals’ construction to improve village health posts /street clinics and strengthen the national and governmental compensating mechanism for township /community health organizations (village health posts /street clinics), so as to make the basic condition of current township/ community health organizations (village health posts /street clinics) better.
ObjectiveTo investigate the prevalence and risk factors for hypertensive women in Chengdu communities, as well as the urban-rural differences. MethodsCluster random sampling method was used. Cross-sectional data on questionnaire for physical examination and laboratory tests were collected from study of 1 202 women in urban and rural Chengdu between February and October 2010. ResultsThis study enrolled the total of 1 202 women aged from 35 to 70 in Chengdu communities, where 616 were from urban areas and 586 from rural areas. Of them, 402 had hypertension with an overall prevalence rate of 33.44% and with the standardized prevalence of 35.27%. The prevalence of hypertension in urban women (42.86%) was higher than that of rural women (23.55%); the difference was statistical (χ2=13.057, P<0.001). The prevalence of hypertension increased with the age increase. The highest cardiovascular risk factors coexisted with hypertensive women was high waist circumference (abdominal obesity), followed by triglyceride (33.33%), total cholesterol (TC) (33.08%), impaired glucose tolerance (38.86%), impaired fasting glucose (IFG) (24.38%), body mass index (16.67%), and high density lipoprotein cholesterol (0.75%). The urban hypertensive women had higher the ratio and average of high waist circumference, IFG and TC than thoes from rural areas with a statistically difference (P<0.05). ConclusionHypertension prevalence in women from rural areas is higher than that in women from urban areas. The urban hypertensive women has higher ratio of risk factors than thoes from rural areas.
ObjectiveTo investigate the status-quo of urban and rural residents' depression in the communities of Chengdu city and its influencing factors. MethodsA multi-stage stratified cluster sampling survey was carried out from February to October 2010. Residents aged from 35 to 70 years in 4 urban and rural communities of Chengdu were investigated in the incidence of depression. The health survey questionnaire and PHQ-2 Depression Screening Scale were used for the household investigation. Data was analyzed using SPSS 18.0 software, and the risk factors were also analyzed using multivariate logistic methods. ResultsA total of 2 027 residents were interviewed, including 1 015 urban (616 women and 399 men, with mean age of 58.90 ±9.48 years) and 1 012 rural residents (582 women and 430 were men, with mean age of 54.94 ±9.64 years). The results showed that the overall depression prevalence rate of residents aged from 35 to70 years old in Chengdu was 2.91% (59/2 027); and the prevalence was 4.33% (44/1 015) in urban and 1.48% (15/1 012) in rural. The prevalence was significantly higher in urban areas than that in rural areas (χ2=13.296, P < 0.001). The results of multivariate analysis showed that a significant difference was found in the prevalence of depression among the different marital status groups, and more divorced people suffered from depression. No statistically significant correlation was found between the factors (including occupation, education level and family income status) and depression. ConclusionThe prevalence of depression among residents in urban and rural communities of Chengdu was high, and the divorced population should be paid more attention to in the prevention and treatment of depression.
ObjectiveTo investigate the prevalence and risk factors of chronic obstructive pulmonary disease (COPD) in urban and rural male residents of Chengdu city. MethodsA cross-sectional survey about the incidence of COPD using cluster random sampling methods was carried out from February to December 2010 among male residents aged 40 to 70 years in four communities in Chengdu city, which was conducted by applying questionnaire survey, physical examination, portable spirometry, etc. Data was analyzed by using SPSS 18.0 software, and the risk factors were also analyzed by using the multivariate logistic methods. ResultsA total of 631 male residents were included, 301 urban and 330 rural. The results showed that: after population standardization, among male residents aged 40 to 70 years in four communities in Chengdu city, the overall prevalence of COPD was 7.95%, and the prevalence was 12.07% in rural area and 7.05% in urban area (P < 0.001). The results of multivariate logistic regression analysis showed that area, age, BMI and smoking volume were the main risk factors of COPD among male. ConclusionThe prevalence of COPD in Chengdu city is relatively higher, which is much higher in rural area than that in urban area. The risk factors are various, and thus comprehensive prevention and treatment of COPD should be emphasized.
ObjectiveTo provide policy suggestions concerning the distribution of health resources between urban and rural areas and management and education of diabetes, this study depicted the current status of access to healthcare and analyzed its determinants among Chinese diabetic patients.MethodsMultivariate ordinal logistic regression and multivariate binary logistic regression were employed to analyze the effects of socioeconomic status and urban-rural disparities on health access.ResultsMultivariate results suggested that urban patients were more likely to conduct more blood glucose tests (P<0.000 1) and receive more self-care suggestions from physicians (P=0.02). After controlling all other covariates, patients graduated from secondary schools and those with vocational school degrees or above were 1.61 and 2.44 times more possible to take more blood glucose tests.Conclusions There exists significant urban-rural disparities of access to healthcare among Chinese diabetic patients. Education may be a key factor of access to healthcare among Chinese diabetic patients. It’s highly recommended to implement education programs on diabetes management in rural areas, where the education status and demographic factors should be considered. The distribution of health resource in rural areas requires more policy and governmental support.
ObjectiveTo explore the regional and urban-rural disparities in the hypertension incidence of Chinese adults. MethodsBased on the data from the China Health and Nutrition Survey (CHNS), as well as the consumption level and altitude data from the National Bureau of Statistics and government official website, a robust multilevel Poisson regression was performed to explore the regional and urban-rural disparities in the hypertension incidence of Chinese adults, according to data and design types. ResultsAccording to the inclusion and exclusion criteria, 11 579 subjects and totaling 50 957 lines of data were enrolled. The 24 years follow-up results indicated that the crude incidence density of hypertension was 37.08/1 000 person years, with 40.51/1 000 person years for males and 34.13/1 000 person years for females. The robust multilevel Poisson regression results indicated that, by adjusting the high-level factors such as time, the proportion of the community mainly engaged in agricultural labor, and the consumption level of subjects, as well as sociodemographic characteristics such as age and gender, the Middle (RR=1.20, 95%CI 1.04 to 1.39), Northeast (RR=1.25, 95%CI 1.03 to 1.52), and Eastern (RR=1.25, 95%CI 1.05 to 1.48) China had a higher risk of developing hypertension than the Western China. The risk of hypertension in urban area was lower than that in rural area (RR=0.87, 95%CI 0.77 to 0.96). ConclusionThe incidence density of hypertension in China is relatively high, and male is higher than female. The incidence of hypertension in the Western China is lower than that in the Middle, Northeast and Eastern China, and urban area is lower than rural area.
