[Status and influential factors of water-borne diseases in bathing beaches in three cities of China from 2019 to 2020].

OBJECTIVE: To understand the health status and influencing factors of people in bathing beach after bathing. METHODS: A questionnaire survey was conducted among the beach tourists in Hebei, Shandong and Shanghai Provinces from May to September, 2019-2020, including personal basic information, seawater/beach exposure in the last 7 days, beach activities, personal protective measures, physical health, related symptoms or diseases after bathing, etc. The seawater samples and sand of the three bathing beaches were sampled and detected. RESULTS: A total of 1222 valid questionnaires were collected. Skin infection(26. 19%), nasal congestion(12. 36%) and eye infection(8. 18%) were the most common symptoms of the tourist after seawater bath. Multivariate logistic regression analysis showed that previous physical discomfort(OR=0. 08-140. 73, 95%CI 0. 04-443. 64) was the common factor of all symptoms(P& lt; 0. 05), the risk factors of stomach cramps, eye infection, nasal congestion and sore throat were no wear of turbinate(OR=4. 65, 95% CI 1. 53-14. 08) and goggles(OR=541. 52, 95% CI 121. 58-2411. 85), swallowing seawater(OR=2. 29-79. 78, 95%CI 19. 83-296. 78) respectively(P& lt; 0. 05). CONCLUSION: Personal protective measures and physical conditions affect people& apos; s symptoms and diseases after bathing. There is microbial pollution in beach water and sand.

[Application of a technology based on JavaEE in National Rural Environmental Health Monitoring Information Management System].

OBJECTIVE: To establish a national rural environmental health monitoring information management system supporting the application and management of four levels of data at the county, municipal, provincial and national levels, to realize the inter-departmental and cross-platform interconnection service of the national environmental health monitoring information management system. METHODS: JavaEE and BS architecture platform, Web Service, XML and other data application and exchange service technologies were used to set data entry and audit functions, such as logic verification, extreme value verification and inter-table relationship verification for key variables, and also used to make the computer interface automatically configured. RESULTS: The functions of data entry, audit, exchange, historical data query and download, system management and maintenance, monitoring system feedback, data reporting progress of the national rural environmental health monitoring information management system across different departments and platforms can be realized by the JavaEE technology. CONCLUSION: The national rural environmental health monitoring information management system was simple in operation and friendly in interface, and had a good application prospect in the field of public health monitoring data management.

A Spatio-Temporal Pattern and Socio-Economic Factors Analysis of Improved Sanitation in China, 2006⁻2015.

Ensuring an adequate and safe access to sanitation is essential to prevent diseases. Using provincial spatial panel data reported in the China Health Statistical Yearbook and the China Statistical Yearbook, this paper analyzed the spatio-temporal characteristics of improved rural sanitation in 30 Chinese provinces during the period 2006⁻2015, and analyzed factors that may affect improved sanitation rates in rural China. Spatial autocorrelations of improved sanitation rates were computed via Global and Local Moran's I firstly, and then, inter-provincial disparities of improved sanitation were assessed by using the Theil index estimator; finally, the spatial panel model was employed to examine the potential socio-economic factors. Spatial autocorrelations results suggested that the provincial improved sanitation rates changes affect both the provinces themselves and the adjacent regions; Analysis of the spatial panel model revealed that factors such as GDP per capita, investment proportion ratio, centralized water supply, rural residents' expenditure were positively associated with improved sanitation rates, and illiteracy rate of people older than 15 was negatively related with improved sanitation rates. Socio-economic factors had affected the improved sanitation rates in 30 provinces in rural China. Thus, a series of policies, socio-economic measures and personal latrine literacy education should be given to improve the status of improved sanitation rates in rural China.
