RÉSUMÉ
Objective To understand the prevalence and risk factors of hyperuricemia in electronics factory workers in Wuhan, and to provide evidence for the health protection of electronics factory workers. Methods A total of 1 415 employees in an electronics factory in Wuhan were selected as the research subjects, and the physical examination and determination of various biochemical indicators, as well as questionnaire survey were carried out. Results The detection rate of hyperuricemia among workers in the electronics factory in Wuhan was 32.43%, with 36.33% for men and 14.11% for women, and the difference was statistically significant ( χ2＝46.077，P＜0.001). The detection rate of hyperuricemia was the highest (33.77%) among those with university or college education, followed by graduate students and above (31.50%). Compared with subjects with good lifestyle habits, people with drinking habits had higher hyperuricemia detection rate (49.38%), and the difference was statistically significant (P =0.001). The detection rates of hyperuricemia in those with central obesity and elevated alanine aminotransferase were 48.23% and 61.29%, respectively, which were significantly higher than those in the subjects without the above diseases (26.91% and 27.21%, respectively), and the differences were statistically significant (P 2 (OR=2.175, 95% CI=1.686 -2.806, P <0.001) were risk factors for hyperuricemia in electronic factory workers. Elevated alanine aminotransferase (ALT) was significantly correlated with hyperuricemia (OR=2.964, 95%CI=2.146-4.095 , P <0.001). Female gender was a protective factor for hyperuricemia in workers in the electronics factory (OR=0.441, 95%CI=0.297-0.653 , P <0.001). Conclusion The detection rate of hyperuricemia among workers in an electronics factory in Wuhan is high, and the detection rate of hyperuricemia in men is higher than that in women. Alcohol consumption, overweight and obesity will increase the risk of hyperuricemia. Elevated ALT is associated with hyperuricemia. Maintaining an ideal body mass index and establishing a good lifestyle play an important role in preventing hyperuricemia.
RÉSUMÉ
Objective To explore the results, feasibility and existing problems of semi-quantitative and quantitative risk assessment models in the assessment of chemical hazard exposure in optical fiber manufacturing enterprises. Methods The chemical hazard factors of an optical fiber enterprise in Wuhan were investigated, detected and evaluated, and the semi-quantitative and quantitative risk assessment models of occupational health of chemical hazard factors in the workplace were used for risk assessment. Results In the semi-quantitative risk assessment model, the consistency between the contact index method and the comprehensive index method was good (Kappa=0.820, P2=0.539，P<0.05), and the results were grade 1, 2, 3 and 5. The non-carcinogenic risk hazard quotient of the quantitative risk assessment model was not consistent with the three semi-quantitative methods (Kappa=0), and the results were grade 1, 2, 3, 4 and 5. Conclusion The semi-quantitative risk assessment model is more suitable for the risk assessment of the optical fiber industry than the quantitative risk assessment model.
RÉSUMÉ
OBJECTIVE: To compare the applicability of three semi-quantitative methods for risk assessment for occupational health in a mechanic processing enterprise. METHODS: The judgment sampling method was used to select a mechanic processing enterprise as the study subject. The occupational health risk was evaluated using contact ratio, exponential and comprehensive exponential analyzing method, and the results of different methods were compared. RESULTS: The occupational health risk level of all the posts in sandblasting, sawing, welding, grinding and painting in the mechanic processing enterprises were of moderate risk or above. The consistency of evaluation results of the contact ratio, exponential and comprehensive exponential methods was poor(weighted Kappa=0.30, P>0.05). The consistency of exponential and comprehensive exponential methods was excellent(weighted Kappa=1.00, P<0.01). When the contact concentration(E)/occupational exposure limits(OEL) is <0.50, the contact ratio method is less than or equal to the exponential method and the comprehensive exponential method. When 0.50 ≤E/OEL<2.00, the results of these three methods are consistent. When the E/OEL ≥2.00, the evaluation result of the contact ratio method is equal to or higher than the exponential method and the comprehensive exponential method.CONCLUSION: The contact ratio method is easy to obtain, simple and convenient. The exponential method is suitable for occupational disease risk factors in the workplace without OELs or unable to obtain test data, and it is more practical. The comprehensive exponential method is considered comprehensive and suitable for occupational health risk assessment in the workplace.
