OBJECTIVETo investigate noise hazard and its influence on hearing loss in workers in the automotive component manufacturing industry.

METHODSNoise level in the workplace of automotive component manufacturing enterprises was measured and hearing examination was performed for workers to analyze the features and exposure levels of noise in each process, as well as the influence on hearing loss in workers.

RESULTSIn the manufacturing processes for different products in this industry, the manufacturing processes of automobile hub and suspension and steering systems had the highest degrees of noise hazard, with over-standard rates of 79.8% and 57.1%, respectively. In the different technical processes for automotive component manufacturing, punching and casting had the highest degrees of noise hazard, with over-standard rates of 65.0% and 50%, respectively. The workers engaged in the automotive air conditioning system had the highest rate of abnormal hearing ability (up to 3.1%).

CONCLUSIONIn the automotive component manufacturing industry, noise hazard exceeds the standard seriously. Although the rate of abnormal hearing is lower than the average value of the automobile manufacturing industry in China, this rate tends to increase gradually. Enough emphasis should be placed on the noise hazard in this industry.

Objective: To investigate the prevalence and related risk factors of prostate diseases in traffic policemen. Methods: A total of 848 traffic policemen who took part in the physical examination among August and September in 2016 were selected as research subjects, and a questionnaire survey was conducted to collect their information including smoking, alcohol drinking, biological and physiological indicators, as well as prostate disease etc. The relationship between the prevalence of prostate diseases and related risk factors was analyzed by Non-conditional Logistic Regression. Results: The total prostate disease prevalence rate was 40.2% in the study subjects, and there is statistical significance (P<0.05) of differences between prostate disease group and non disease group in age, work age, smoking, drinking and field work. Single factor analysis showed that age, work age, smoking, and field work are independent risk factors of prostate disease (P<0.05) . Multivariate Logistic regression analysis showed that increasing age (OR 1.03) , smoking (OR 1.92) and field work time (OR 1.47) significantly increased the risk of prostate disease in male police after age, smoking, drinking, BMI, systolic blood pressure, diastolic blood pressure, fasting blood glucose, blood lipids and other indicators were adjusted. Conclusion age, smoking and field work time are risk factors of prostate diseases in the traffic police. There is great significance in publicizing the harmful effects of smoking and reducing the duration of field work.

OBJECTIVE: To comprehend the prevalence status of elevated serum uric acid(SUA) and investigate the relationship between elevated SUA and cardiovascular risk factors and the clustering of the cardiovascular risk factors among outdoor male traffic policemen. METHODS: Selected by convenience sampling,1 039 outdoor traffic policemen in Guangzhou were asked to complete a questionnaire survey,physical and laboratory examination. According to the level of SUA > 420. 00 μmol/L or not,they were divided into elevated SUA group and control group. RESULTS: The median SUA level of outdoor male traffic policemen was 431. 00 μmol/L,and the elevated SUA prevalence was 56. 3%. The length of working years,systolic blood pressure,diastolic blood pressure,and levels of serum triglyceride(TG),total cholesterol(TC),low density lipoprotein cholesterol(LDL-C),and serum creatinine(Scr) in the elevated SUA group were statistically higher than the control group(P < 0. 01). The high density lipoprotein cholesterol level was lower in the control group than that in the elevated SUA group(P < 0. 01). After adjusting for age and alcohol consumption,the results of multivariate logistic regression analyses showed that outdoor traffic policemen who suffer from overweight or obesity,elevated TG and elevated TC have more risk in suffering from elevated SUA(P < 0. 05). The odds ratios(ORs) and 95%confidence intervals(CIs) were 2. 347(1. 772-3. 109),2. 040(1. 517-2. 743) and 1. 431(1. 080-1. 896) respectively.The risk factors of suffering from elevated SUA increased along with the increase of outdoor working years or Scr level(P <0. 05). The ORs and 95% CIs were 1. 028(1. 004-1. 054) and 1. 048(1. 033-1. 062) respectively. The proportion of people with elevated SUA among outdoor traffic policemen increased with the increase of cardiovascular risk factors(P <0. 01). The risk of elevated SUA among outdoor male traffic policemen who have 1,2,3,4 and ≥5 cardiovascular risk factors were 1. 583,2. 351,4. 657,2. 865 and 13. 576 times higher than those without cardiovascular risk factor respectively(P < 0. 05). CONCLUSION: Among outdoor male traffic policemen,elevated SUA are closely associated with the cardiovascular risk factors. The risk factors of suffering from elevated SUA increased with clustering of cardiovascular risk factors.

OBJECTIVETo analyze the health examination results of Guangzhou traffic police officers in 2013, and to investigate their health status and provide a scientific basis for the health management of traffic police officers.

METHODSThe physical examination data of the Guangzhou traffic police officers in 2013 were analyzed. The data were sorted in Excel and analyzed using SPSS software.

RESULTSThe results showed that 82.95%of the Guangzhou traffic police officers who underwent physical examination in our hospital in 2013 had diseases or abnormal examination indices. The diseases or abnormal examination indices that ranked among the top three were hyperlipidemia (53.70%), hyperuricemia (46.51%), and overweight/obesity (43.43%). All diseases or abnormal examination indices except thyroid diseases were significantly higher in males than in females (P < 0.05). The proportion of diseases or abnormal examination indices varied significantly between different age groups (P < 0.05). Among the 345 female traffic police officers, the prevalence of mammary gland hyperplasia or mammary nodules was the highest, and the prevalence of mammary gland hyperplasia or mammary nodules, cervicitis, and uterine fibroids varied significantly between different age groups (P < 0.05).

CONCLUSIONThe health problems in Guangzhou traffic police officers are serious, especially chronic noninfectious diseases. Therefore, both society and individuals should take effective measures in order to deal with this problem. Regular health check-ups are necessary to promote good health for Guangzhou traffic police officers.

Objective: To analyze the relationships between the exposure of occupational noise and the occurrence of noise-induced high frequency hearing loss in automobile manufacturing industry. Methods: From June to November 2017, 1579 male workers were selected for exposure to noise hazards in the automobile manufacturing industry in Guangzhou for more than one year (including one year) using the convenient sampling method. According to the hearing test results, 276 people in the high frequency hearing loss group and 1303 in the normal hearing group were surveyed, occupational health tests were conducted, and the noise intensity in the workplace was measured. The cumulative noise exposure (CNE) was calculated. The relationship between shift work and high frequency hearing loss of noise work is analyzed. Results: Compared with the normal hearing group, the noise exposure intensity, age, length of service, marital status, working system, and physical exercise of the high frequency hearing loss group were statistically significant (P<0.05). Through logistic regression analysis, after correcting the effects of organic solvent contact, marital status, and physical exercise, CNE, age, and shift operations (double-shift operations, three-shift operations) are the risk factors for high frequency hearing loss to occur. Conclusion The risk of hearing loss of workers exposed to noise in the whole vehicle manufacturing industry may be related to CNE, age, and shift work. Two-shift and three-shift work are possible risk factors for noise-induced high frequency hearing loss.
