ABSTRACT
As an important part of health information standard system, occupational health information standard system is the foundation and guarantee of promoting the construction of occupational health information. This article is based on the literature research about current situation of domestic and foreign health information standards and occupational health information standard system, thus take "the National Health Information Standardization System" and "the National Public Health Information Construction Standards and Norms" into account, focus on the requirements of occupational health information construction and related work. Thus, put forward suggestions on the construction of occupational health information standard system, to accelerate the occupational health information construction, data collection, transmission and application.

OBJECTIVE: To analyze the prevalence of work-related musculoskeletal disorders(WMSDs) among dentists and explore its influencing factors. METHODS: A total of 455 dentists from 9 medical organizations of Beijing and Fuzhou cities were selected as study subjects. The disease occurrence and mental workload were investigated using China Musculoskeletal Disorders Questionnaire and Subjective Workload Assessment Technique. The influencing factors of WMSDs were analyzed by multivariate logistic regression. RESULTS: The total prevalence of WMSDs was 58.9%(268/455) among dentists. The top three body parts of WMSDs were neck(41.5%), shoulder(33.6%) and lower back(28.1%). The median of mental workload score was 58. Multivariate logistic regression analysis results indicated that female dentists showed a higher risk than male dentists(P<0.01) after excluding the influence of confounding factors. The higher the length of service, the higher their risk for WMSDs(P<0.01). Dentists who hold their heads sideways for long time, bent frequently, and use vibrating tools had relatively high risks of developing WMSDs(P<0.01). Dentists who use armchairs had a relatively low risk of WMSDs(P<0.01). There was no correlation between the mental workload and the prevalence of WMSDs in dentists(P>0.05). CONCLUSION: The prevalence of WMSDs among dentists is high. Individual factors, awkward posture and using vibrating tools are risk factors of WMSDs among dentists.Armchair use can help reduce the risk of WMSDs.
ABSTRACT
OBJECTIVE: To investigate the prevalence of lower extremity work-related musculoskeletal disorders(WMSDs) among manufacturing workers, and to explore the association of lower extremity WMSDs and different types of working. METHODS: A total of 7 908 workers were selected as study subjects from four manufacturing factories in China using the cluster sampling method. The Musculoskeletal Disorders Investigating Questionnaire was adopted to investigate the prevalence of lower extremity WMSDs and the distribution of types of working. The prevalence ratio(PR) of WMSDs, calculated by log-binomial model, was used to estimate the correlation of WMSDs in different parts of lower extremity. The multi-factor logistic regression was used to analyze the association of lower extremity WMSDs and different types of working. RESULTS: The total annual prevalence of lower extremity WMSDs was 41.0%(3 241/7 908) among manufacturing workers. The annual prevalence of WMSDs of different parts in lower extremity from high to low were knee(29.5%), ankle/foot(23.9%) and hip/thigh(16.7%). The correlation of WMSDs of the three parts in lower extremity was close, and the range of PR values was 2.21-3.88. The result of logistic regression analysis showed that the workers who frequently sat for long periods had higher risk of lower extremity WMSDs than those who never/rarely sat for long periods(odds ratio=1.39, P<0.01). The higher the frequency of standing, kneeling/squatting for long periods, carrying heavy loads ≥5 kg and driving, the higher the risk of lower extremity WMSDs(the odds ratios were 1.33, 1.41, 1.16 and 1.12, respectively, P<0.01). CONCLUSION: The prevalence of lower extremity WMSDs was relatively high among manufacturing workers. There is a dose-effect relationship between the types of working and lower extremity WMSDs.
