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.
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.
