ABSTRACT
Objective@#To analyze the hearing self-protection behavior patterns and internal factors of workers exposured to occupational noise in an aircraft manufacturing industry based on health belief model, so as to provide reference for further health promotion programs and intervention measures.@*Methods@#A total of 1600 front-line workers were selected from 10 units of an aircraft manufacturing enterprise by cluster sampling method. The basic and occupational information of employees were collected, and a self-reported questionnaire was designed according to the health belief model to acquire the hearing self-protection behaviors of workers.@*Results@#There were significant differences in the perceived severity, perceived benefit, perceived impairment, self-efficacy and behavioral incentive scores of different hearing self-protection behaviors among the noise-causing workers (P<0.05). There were significant differences in the distribution of hearing self-protection behaviors among different genders, ages, education levels, length of service, initial noise exposure time and cumulative noise reception time (P<0.05). The perceived benefits, perceived barriers, behavioral incentives, self-efficacy scores, and educational attainment of the noise-causing workers were all related to the type of hearing self-protection behavior (P<0.05) .@*Conclusion@#The educational level and health belief model can predict the hearing self-protection behavior patterns of front-line workers to some extent, more attention should be paid to the monitoring of the well-educated employees.
ABSTRACT
Objective To establish a predictive model for inpatients of cardio-cerebrovascular disease in rural areas of Wugang through time series analysis, and predict the changing trend of cardio-cerebrovascular disease, so as to offer guidance for the health care resources allocation and prevention and control of cardio-cerebrovascular disease. Methods The seasonal autoregressive integrated moving average model (SARIMA) was constructed based on the monthly number of cases of cardio-cerebrovascular disease in rural areas from January 2013 to December 2016 by Stata 14.0 software, and the predictive effect of the model was verified with the monthly number of inpatients of cardio-cerebrovascular disease in 2017. Results The final fitting model of inpatients of cardio-cerebrovascular disease was SARIMA (2, 1, 1)×(0, 1, 0)12. The residual sequence of the model was diagnosed. Results of Ljung-Box Q test showed that the residual sequence was white noise sequence (Q=11.12, P=0.68). In addition, the 2017 forecast was basically consistent with the observations, the overall relative error was around -1.2%. The results showed that the summer was the peak period of cardiovascular and cerebrovascular hospitalization. Conclusion SARIMA model can accurately predict the number of inpatients of cardio-cerebrovascular disease in Wugang, which can provide data support for the hospital administrator to rationally allocate medical resources in the cardiovascular according to the needs of cardio-cerebrovascular treatment in different months.
ABSTRACT
Objective@#To find out the status of the monitoring of production environment and physical condition of occupational victims in Sichuan in recent 5 years.@*Methods@#Data of health supervision of workers with toxic and harmful activity and occupational health examination in Sichuan Province during 2012-2016, monitoring of occupational harmful factors in Sichuan Province during 2014-2016 were collected from the Network direct reporting system. Descriptive analysis was conducted to analyze the result in May 2017.@*Results@#The detection rate of suspected occupational diseases in 23964 enterprises was 1.79% (13392/748291) . The exceeding standard rate of dust, noise, xenobiotic were 32.58% (5089/15622) , 20.28% (4897/24152) and 4.80% (1016/21145) respectively. In addition, state-owned enterprises, state-owned enterprises and collective enterprises showed the highest over-standard rate of dust, noise and exogenous chemical poisons, with the over-standard rate of 69.93% (828/1184) , 29.08% (608/2091) and 11.80% (42/356) respectively. The exceeding rate of dust, noise and exogenous chemical poisons was 32.76% (740/2259) , 28.72% (444/1546) and 7.39% (114/1543) , respectively. Most of the enterprises with higher over-standard rate of dust and chemical poisons are located in Suining City, Panzhihua City, Guangyuan City and Ziyang City.@*Conclusion@#The focus of occupational hazards in Sichuan is dust and noise, followed by benzene.
ABSTRACT
Objective@#To evaluate the quality of Pneumoconiosis Network Direct Report in Sichuan Province in 2006-2016.@*Methods@#download all the pneumoconiosis report cards from the Network Direct Report system. Screen out cards based on the diagnosis time that is between January 1st 2006 and December 31st 2016. Using R 3.4.0 software to analysis the number of missing or repeated cards, time-logical error rates, timeliness, reporting year, reporting intervals to evaluate the quality of Pneumoconiosis Network Direct Report and location distribution.@*Results@#there are 38 855 pieces of Pneumoconiosis report card in total in 2006-2016. 352 pieces of cards were reported twice. 224 cards were missing. 229 cards have time-logical error. The rate of timely reporting for 2006-2016 years was 66.41% (2 5453/38 326) , 67.14% (24 658/36 726) for new cases, 58.87% (783/1 330) for promoting cases and 4.44% (12/270) for deaths. 87.38% (33 490/38 326) patients was reported in the same year. 10 days was needed to finish one report, confirming-filling cost much more time than filling-report (9.865/49.019) .@*Conclusion@#the records of pneumoconiosis report cards are much more complete, logical errors are less, and the timeliness was a little bit higher than the average level in China. But it also should be improved. The death cases are difficult to report. It takes longer to diagnose and fill in cards. Improving the timeliness rate can significantly improve the quality of network direct reporting.
ABSTRACT
Objective@#To evaluate occupational stress and perceptions of the work experience among the nurses, and to analyze the effects of recovery experiences on the adjustment of the relationship of stress and perceptions of the work experience. @*Methods@#A questionnaire survey was conducted among nurses from 7 third hospitals in a city through sampling. A self-designed questionnaire, "Job Content Questionnaire (JCQ) " , "Recovery Experience Questionnaire (REQ-C) " and "Quality of working life (QWL7-32) " were completed by the subjects. Establishment of recovery experience types by sample cluster analysis, combined with regression analysis in the regulation of perceptions of the work experience of recovery experiences’types. @*Results@#There have differences instatus and score of perceptions of the work experience among nurses with different tension level (P<0.05) . The Perceptions of Work Experience scores of nurses with different types of recovery experience are different with the tension level, and the type of recovery experience has an independent moderating effect on the relationship between tension and perceptions of work experience. @*Conclusion@#The moderating effects of different types of recovery experiences on perceptions of work experience are different.
