Analysis of the correlative characteristics of national occupational health standards based on social network analytic method / 中国职业医学

ABSTRACT

OBJECTIVE: To explore the correlative characteristics of the National Occupational Health Standards by social network analytic method. METHODS: The national occupational health standards were searched and collected through the National Health Commission of the People′s Republic of China and the National Institute of Occupational Health and Poison Control, Chinese Center for Disease Control and Prevention. And the normative reference file related information was extracted to build standard coupling matrix. UCINET6 software for Windows was used to compute the node feature specifications. The network topology diagram of standard mutual citation relationship was drawn using Netdraw 2.054. RESULTS: A total of 269 national occupational health standards were included, involving 361 normative references files. Among them, the highest degree centrality was 48.064 in GBZ/T 251 Guidelines for Prevention and Control of Occupational Hazard in Foundry of Automobile Manufacturing. The highest closeness centrality and betweenness centrality were 27.386 and 33.210, respectively, in GBZ 2.1 Occupational Exposure Limits for Hazardous Agents in the Workplace--Part 1 Chemical Hazardous Agents. The topographic map of standard mutual reference network indicated that five national occupational health standards were located in the central position of the mutual reference network, which included GBZ 1 Hygiene Standards for the Design of Industrial Enterprises, GBZ 2.1 Occupational Exposure Limits for Hazardous Agents in the Workplace--Part 1 Chemical Hazardous Agents, GBZ 2.2 Occupational Exposure Limits for Hazardous Agents in the Workplace--Part 2 Physical Agents, GBZ 158 Warning Sign for Occupational Hazards in the Workplace and GBZ 159 Specifications of Air Sampling for Hazardous Substances Monitoring in the Workplace. CONCLUSION: The five national occupational health standards located in the central position of the mutual reference network were the key nodes that have a greater influence on other standards, and can be the focus of future standard management.
