Analysis of the Spatio-temporal Characteristics and Influencing Factors of Local Hospitalization Propor-tion of Guangdong Province / 中国医院管理

Objective To analyze the spatio-temporal characteristics and influencing factors of local hospitalization proportion in 57 counties of Guangdong Province.Methods Using local hospitalization proportion and related indicators in 57 counties of Guangdong Province from 2016 to 2019,temporal trend analysis and spatial autocorrelation analy-sis were used to analyze the spatiotemporal characteristics.Bayesian spatio-temporal model was used to explore in-fluencing factors of local hospitalization proportion.Results The local hospitalization proportion in Guangdong Province rose from 79.8%in 2016 to 84.1%in 2019,showing an increasing trend and the overall characteristics of"high in the west and low in the east".The global and local spatial autocorrelation results show that there is a spatial correla-tion in the local hospitalization proportion within the counties of Guangdong Province,and spatial aggregation has formed in some areas.There is a"high"aggregation in western Guangdong,and a"low"aggregation in eastern Guangdong Province.The Bayesian spatio-temporal model shows that the number of people with a bachelor's de-gree or above per 1 000 population and the CMI of county hospitals had an effect on the local hospitalization propor-tion(P＜0.05).Conclusion Guangdong Province can improve the medical service capacity of county hospitals sub-stantially and introduce or train high-quality talents through multiple measures,and continue to improve the local hospitalization proportion.

Relationship between current smoking behaviors and household characteristics in Guangdong / 中华流行病学杂志

<p><b>OBJECTIVE</b>To disclose the relationship between current smoking behaviors and household characteristics among adults in Guangdong, in order to provide scientific evidence for household tobacco control strategy.</p><p><b>METHODS</b>A questionnaire survey was conducted among the adults sampled by four-stage randomized cluster sampling in ten districts of five cities in Guangdong from September to November, 2010. The questionnaire included demographic characteristics, smoking behaviors and smoking-related household characteristics. Chi-square test and unconditional logistic regression analysis were employed to explore the relationship between current smoking behaviors and household characteristics.</p><p><b>RESULTS</b>This study included 2 150 respondents, with data from 2 121 eligible questionnaires used for analysis. The current smoking rates for respondents with household characteristics including per capita household income below 1 000 Yuan, three or more smokers in the family, no ban of smoking at home and treating visitors with cigarettes were 28.7%, 56.5%, 34.2% and 43.5% , respectively, and were significantly higher than those for respondents with household characteristics at other levels (P < 0.01 for all). After controlling for factors such as gender, age, personal income, education, employment status and residential location, we found that the number of family smokers, smoking restrictions at home and treating visitors with cigarettes had significant association with current smoking behaviors (P < 0.01 for all), except for per capita household income (P = 0.567).</p><p><b>CONCLUSION</b>Household is one of the effective places in carrying out health education and tobacco control intervention. In order to reduce tobacco use, much effort should be made to create smoke-free homes, encourage smoking cessation and treat visitors with no cigarettes.</p>

Using biomass fuel at home and the development of hypertension in adult women living in rural areas of Guangdong: a multilevel model analysis / 中华流行病学杂志

<p><b>OBJECTIVE</b>To understand the situation of biomass fuel use in rural Guangdong, and how it affecting the prevalence of hypertension in adult women.</p><p><b>METHODS</b>Inhabitants aged 18 and above were chosen, using multi-stage stratified cluster sampling method from 13 rural countries in Guangdong province in 2010. Questionnaire survey and blood pressure measurement were conducted. Multilevel logistic regression model was used to study the relationship between biomass fuel use and the prevalence of hypertension at both country and individual levels.</p><p><b>RESULTS</b>Of the 5794 rural families, 2 569 (44.3%) cooked with biomass fuel in the kitchen. 1233 (46.2%) and 1 436 (53.8%) out of the 2669 adult women used biomass fuel and clean energy, respectively. Results from χ² study showed that biomass users presented higher prevalence of hypertension (RR = 1.26, 95% CI: 1.04-1.52), but in multilevel model analysis, the difference was not significant. In addition, using an extractor fan when cooking seemed to have protected factor in decreasing the risk of hypertension among biomass users (RR = 0.61, 95% CI: 0.39-0.98).</p><p><b>CONCLUSION</b>Proportion of the use of biomass fuel was still high among rural families in Guangdong province. Although there was not enough evidence to verify the relationship between the use of biomass fuel and hypertension in adult women. However, concerns about the use of biomass fuel which causing the indoor air pollution, should be raised.</p>
