ABSTRACT
Objective@#To investigate the current status and influencing factors of occupational stress among couriers.@*Methods@#Couriers (n=925) were selected on this study used cluster sampling method from January to March 2018. They were from SF and Zhongtong Express Co., Ltd., on the Wechat platform, and surveyed by a job stress questionnaire based on a job demand-control model.Valid questionnaires(n=617) were obtained.@*Results@#A total of 418 workers were occupational stress positive (67.7%). The results of Chi-square analysis showed that there were significant differences in occupational stress among workers categorized by job position, working years, mealtime, sleeping time, and weekly work time (P<0.05). The multivariate logistic analysis indicated that non-regular meals, short-term sleep and less than 0.5 working years were risk factors for occupational stress(P<0.05).@*Conclusion@#Couriers generally have occupational stress. The main influencing factors are job position, working years mealtime, sleeping time, and weekly work time. It is necessary to guide healthy lifestyle, rationally organize labor and assign tasks, and improve working environment to relieve their occupational stress.
ABSTRACT
OBJECTIVE: To analyze the influencing factors of suspected occupational noise-induced deafness( ONID) in noise-exposed workers. METHODS: A total of 38 770 noise-exposed workers engaged in occupational health examination were collected as the study subjects from 2012-2016 by judgment sampling method. The data of workers' occupational medical examination was collected,and the incidence and influencing factors of suspected ONID were analyzed. RESULTS: A total of 125 cases of suspected ONID were detected and the detection rate was 0. 32%. The result of multivariate Logistic regression showed that male workers exposed to noise had a higher risk of suspected ONID than female workers( P <0. 01). The odds ratio( OR) and 95% confidence interval( CI) were 1. 98( 1. 22-3. 19). The older the age and the longer service length of workers exposed to noise,the higher the risk of suspected ONID( P < 0. 01). The ORs and 95% CIs were 1. 79(1. 43-2. 25) and 1. 84( 1. 47-2. 30) respectively. The noise-exposed workers had a higher risk of suspected ONID in foreign-funded enterprises than domestic-funded enterprises( P < 0. 01). The noise-exposed workers had a higher risk of suspected ONID in metal manufacturing industries than in non-metal manufacturing industries( P < 0. 01). The ORs and 95% CIs were 1. 83(1. 19-2. 82) and 2. 02(1. 40-2. 94) respectively. CONCLUSION: The incidence of suspected ONID is affected by factors of gender,age,length of service,economy type of enterprises and industry type.
ABSTRACT
<p><b>OBJECTIVE</b>To study the economic burden caused by occupational chronic n-hexane poisoning.</p><p><b>METHODS</b>Information about the cost of treatment, compensation, board, wage, diagnosis, escorts, transportation and the days off work were collected in a 34 cases of occupational chronic n-hexane poisoning accident to estimate the economic burden.</p><p><b>RESULTS</b>There were 4 mild, 19 moderate, 11 severe in the 34 cases and the total cost was 6 084 809 yuan. The hospitalization days was respectively (204.0 ± 3.7) d, (226.6 ± 78.3) d and (417.6 ± 94.1) d, averaging (285.8 ± 96.3) d. The treatment cost was respectively 62 525.8, 69 409.7 and 128 155.6 yuan. The compensation was respectively 20 000.0, 20 052.6 and 30 290.9 yuan. The wage was respectively 23 460.0, 26 062.6 and 47 644.0 yuan. The board was respectively 17 566.5, 19 499.8 and 36 230.1 yuan. The days of work was respectively (176.8 ± 3.2) d, (196.4 ± 67.9) d and (361.4 ± 81.6) d, averaging (247.7 ± 83.5). The lost productivity was respectively 1 809 724.8, 2 010 350.4 and 3 699 290.4 yuan.</p><p><b>CONCLUSION</b>The economic burden of occupational chronic n-hexane poisoning was so heavy that prevention measures should be strengthened.</p>
