ObjectiveTo evaluate the smoking environment, its related knowledge and difference between urban and rural areas in Chengdu. MethodsIn December 2010, we randomly sampled and investigated 60 dwellers aged from 35 to 70 from urban and rural communities, who were 1:1 paired by the age and sex. Questionnaires survey was used. ResultsThere were 48.3% (29/60) dwellers thought that smoking should be allowed freely at home, of which 30.0% (9/30)rural homes had no rules about smoking prohibited. There were 93.3% (28/30) urban dwellers supported male smoking. About 86.7%-98.3% urban dwellers realized that many diseases such as heart disease, stroke, and lung cancer may be due to smoking. And 16.7% urban dwellers also realized that cigarettes can result in diabetes mellitus, but none of rural dwellers did. The publicity of smoking cessation among urban dwellers (91.7%) by mass media was better than rural ones (0.0%). There were 95.0% dwellers denied any institution or organization for smoking control. ConclusionThe dwellers were short of cognition about restrictions of smoking environment and non-smoking knowledge. It's different between urban and rural area in tobacco advertisement and publicity of smoking cessation. We should continue enhancing public education, forbiding tobacco advertisement and providing institutions for smoking control.
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 prevalence and risk factors for chronic obstructive pulmonary disease (COPD) in Dayi County of Chengdu. MethodsRandomly cluster sampled residents between 40 and 70 years of age from two natural villages in the rural communities from February to December, 2010 were included in our study. We used questionnaire survey, physical examination and portable spirometry to collect data. Post-bronchodilator forced expiratory volume in 1 second/forced vital capacity of less than 70% was defined as the diagnostic criterion of COPD. Univariate analysis and logistic regression mode were used to define the risk factors. ResultsA total of 1 017 residents were enrolled in this survey, and 782 participants were valid for analysis, with a valid response rate of 76.89%. There were 330 males and 452 females, with an average age of (51.97±8.17) years old. The overall prevalence of COPD was 10.61%. After population standardization, the prevalence rate was 12.37%, and the overall prevalence increased with increment of age. The prevalence in male (13.33%) was higher than that in female (8.62%) with significant difference (P<0.01) and the prevalence increased with age. Univariate analysis showed that sex, age, education level, smoking and amount of smoking (pack-years) were the risk factors for COPD with significant difference. Logistic regression analysis showed that age, amount of smoking (pack-years) were the main risk factors for COPD. ConclusionCOPD is highly prevalent in Dayi County of Chengdu and it is important to prevent COPD by controlling smoking and improving education level.
