ABSTRACT

Objective: To understand the diagnosis of suspected occupational diseases reported in Guangzhou from 2014 to 2019, so as to provide theoretical basis and technical support for the supervision of suspected occupational disease reports. Methods: By cluster sampling, the suspected occupational disease report card, occupational disease report card and pneumoconiosis report card reported by Guangzhou from January 1, 2014 to December 31, 2019 in the occupational disease and occupational health information monitoring system were collected for matching analysis to understand the diagnosis of suspected occupational disease patients. Results: From 2014 to 2019, a total of 1426 suspected occupational cases in 7 categories and 32 species were reported in Guangzhou. The average number of reported cases per year was about 240. The main diseases of suspected occupational diseases were suspected occupational noise deafness (68.44%, 976/1426) , suspected occupational chronic benzene poisoning (16.48%, 235/1426) , suspected occupational other pneumoconiosis (4.84%, 69/1426) , suspected occupational silicosis (3.23%, 46/1426) and suspected occupational welder pneumoconiosis (1.82%, 26/1426) . The diagnostic rate required to enter the occupational disease diagnostic program is 36.61% (522/1426) , and the diagnostic rate is 59.20% (309/522) . In 2019, the diagnosis rate of suspected occupational diseases was the lowest (23.92%, 61/255) , Huadu District was the lowest (8.33%, 9/108) , suspected occupational pneumoconiosis was the lowest (28.03%, 44/157) , the diagnosis rate of suspected occupational diseases reported by the Centers for Disease control and prevention was the lowest (17.43%, 19/109) , and the diagnosis rate of suspected occupational diseases reported by outpatient treatment was the lowest (22.22%, 2/9) . The suspected occupational diseases reported by institutions outside Guangzhou did not enter the occupational disease diagnosis procedure. Suspected occupational skin diseases, suspected occupational diseases caused by physical factors and suspected occupational tumors were diagnosed, and the diagnosis rate of occupational disease prevention and control institutions was the highest (94.87%, 37/39) . Conclusion: The main types of suspected occupational diseases reported during these six years are noise deafness, chronic benzene poisoning and pneumoconiosis. The overall diagnosis rate and diagnosis rate of suspected occupational diseases are not high. It is suggested to improve the network direct reporting system of suspected occupational diseases and strengthen the follow-up management and supervision of suspected occupational diseases.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the influential factors for job burnout among the managerial staff in a Sino-Japanese joint venture automobile manufacturer in Guangzhou, China.</p><p><b>METHODS</b>A total of 288 managers in a Sino-Japanese joint venture automobile manufacturer were surveyed using the Occupational Stress Indicator, Maslach Burnout Inventory (MBI), Eysenck Personality Questionnaire, Simplified Coping Style Questionnaire, and Social Support Rating Scale.</p><p><b>RESULTS</b>On the depersonalization dimension, the male managers had significantly higher scores than the female managers. The scores of emotion exhaustion and depersonalization of MBI showed significant differences among the managers with different levels of occupational stress. The path analysis showed that occupational stress, neuroticism, and psychoticism had negative effects on emotion exhaustion, while job satisfaction and utilization of social support had direct positive effects on emotion exhaustion. Occupational stress, psychoticism, and passive coping style had direct negative effects on depersonalization, while job satisfaction, objective support, and utilization of social support had positive effects on depersonalization. Job satisfaction and active coping style had positive effects on sense of personal accomplishment, while passive coping style had a negative effect on sense of personal accomplishment. Personality exerted its effect on social support through coping style and thus on job satisfaction and job burnout.</p><p><b>CONCLUSION</b>Male managers have a greater propensity to depersonalization than their female counterparts. High occupational stress is a risk factor for job burnout. Personality, social support, and coping style are influential factors for job burnout.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the influential factors on psychosocial health of the migrant workers in Guangzhou.</p><p><b>METHODS</b>The Symptom Checklist 90 (SCL-90) and Eysenck Personality Questionnaire (EPQ) were used to investigate 518 migrant workers in Guangzhou.</p><p><b>RESULTS</b>The rate of migrant workers with psychosocial problems was 36.5%. The scores of SCL-90 and positive rates in migrant workers with the different personality types had significant difference (P < 0.01). The results of binary logistic regression analysis indicated that the working years, drinking, sex, P scores, E scores and N scores of EPQ were main predictors of the poor physical fitness status. The vocations, working years, P scores and N scores of EPQ were strong predictors of the somatization. he vocations, P scores and N scores of EPQ were strong predictors of the obsessive compulsive symptom. The smoking, P scores and N scores of EPQ were strong predictors of the interpersonal sensitivity. The working years, P scores of EPQ were strong predictors of the depression. P scores of EPQ was strong predictors of the anxiety. P scores, E scores and N scores of EPQ were strong predictors of the hostility. The working years, smoking, P scores, E scores and N scores of EPQ were strong predictors of the phobic anxiety. The working years, P scores of EPQ were strong predictors of the paranoid ideation. The working years, P scores and N scores of EPQ were strong predictors of the psychosis.</p><p><b>CONCLUSION</b>The level of mental health of the migrant workers was significantly associated with the personality. The results of present study indicated that different vocation, sex, working years, smoking and drinking might interfere with the psychological states. The migrant workers with the personality of psychoticism, neuroticism and introversion may have unhealthy mental reaction.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the epidemiological characteristics of occupational diseases in Guangzhou City, China in 2001 - 2010, and to provide a scientific basis for the prevention and control of occupational diseases.</p><p><b>METHODS</b>Statistical analysis was performed on the reported data on the occupational diseases in Guangzhou from 2001 to 2010.</p><p><b>RESULTS</b>A total of 380 cases of occupational diseases (37 types,8 classes) were diagnosed and reported in 2001 - 2010. The three most frequent diseases were occupational poisonings (48.9%), pneumoconiosis (20.0%), and occupational ear, nose, and throat (ENT) diseases (18.7%). In the cases of occupational poisonings, 25.3% suffered from acute occupational poisonings, especially the poisoning by dichloroethane (19.1%), and 74.7% suffered from chronic occupational poisonings, mainly caused by lead (38.8%), benzene (37.4%), and n-hexane (18.0%). The cases of silicosis accounted for 77.6% of all cases of pneumoconiosis. The cases of noise-induced deafness accounted for 97.2% of all cases of occupational ENT diseases. Patients with occupational diseases were reported in 13 districts of Guangzhou, mostly in Panyu (18.9%), Tianhe (13.2%), Baiyun (12.9%), and Liwan (11.1%). All the cases occurred in 19 industries, mainly including light industry (27.1%) and machinery industry (23.7%). Of all cases, 29.5% were in the public sector, 40.3% in the private sector, and 30.3% in the foreign-funded enterprises and those funded by businessmen from Hong Kong, Macao, and Taiwan. The ratio of male to female cases was 15:4. The mean age of onset was 42.2 ± 10.9 years. The average speed of development of occupational diseases was 134.0%, and the average growth rate was 34.0%.</p><p><b>CONCLUSION</b>The incidence of occupational diseases tends to increase year by year, with younger age of onset and shorter history of exposure in patients. The occupational poisonings caused by lead, benzene, n-hexane, and dichloroethane, silicosis, and noise-induced deafness seem to be the main occupational hazards in Guangzhou, China. Occupational diseases occur in all districts of Guangzhou and in various industries. The private sector and small enterprises should be the focuses of occupational health supervision.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study relationships between personality and occupational stress of workers in processing line in Guangzhou.</p><p><b>METHODS</b>452 workers in processing line in Guangzhou were investigated by the Eysenck Personality Questionnaire (EPQ) and Occupational Stress Indicator (OSI).</p><p><b>RESULTS</b>N scores and P scores of EPQ were positively correlated with the occupational stress and the poor physical fitness status (r value was 0.196, 0.128, 0.202, 0.218, respectively) (P < 0.01). N scores of EPQ were positively correlated with the type A behavior (r = 0.164) and negatively correlated with the mental well-being level (r = -0.196, P < 0.01). P scores of EPQ were negative correlated with the sense of job satisfaction and the stress coping ability(r value was -0.146, -0.140, respectively) (P < 0.01). E scores and L scores of EPQ were negatively correlated with the type A behavior (r value was -0.159, -0.138, respectively) (P < 0.01). E scores of EPQ were positively correlated with the stress coping ability (r = 0.176, P < 0.01). L scores of EPQ were negatively correlated with the occupational stress, the poor physical fitness status and the explanation to vicinity event (r value was -0.139, -0.140, -0.111, respectively) (P < 0.01, P < 0.05).</p><p><b>CONCLUSION</b>The personality of neuroticism, psychoticism and introversion may be related to the occupational stress, the sense of job satisfaction and unhealthy mental reaction.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the situation of occupational health surveillance and the characteristics of occupational diseases in Guangzhou.</p><p><b>METHODS</b>The situation of occupational health surveillance and the morbidity of occupational diseases were studied retrospectively by use of the physical examination data collected from the labour hygienic reports of the city from 1993 to 2002. The data were divided into two groups: the first group from 1993 to 1997, and the second from 1998 to 2002.</p><p><b>RESULTS</b>Annual average of occupational health examination in the past 10 years was over 75%. The data in the second group (1998 - 2002) showed that the number of hearing loss observed subjects, noise surveilled personnels, dust and chemicals contraindicated personnels were significantly higher than those in the 1st group (P < 0.01). The morbidity of chronic occupational disease newly occurred was 91 cases in lst group, and 181 cases in 2nd group (P < 0.05), in which the incidence of chemical poisoning and noise induced hearing loss increased significantly but that of pneumoconiosis between two groups was not significantly different (P > 0.05). In the past 10 years, 581 cases of occupational diseases were diagnosed, of which, 309 cases (53.18%) were acute poisonings, while 272 cases (46.82%) were chronic occupational diseases. Pneumoconiosis, lead and benzene poisoning were common in chronic occupational diseases (16.70%, 16.87% respectively). With the passage of time, the incidence ages of pneumoconiosis, chemical poisoning and total occupational diseases tended towards younger. The difference was statistically significant (P < 0.01)</p><p><b>CONCLUSION</b>A normal system for occupational health surveillance has been developed in Guangzhou. Detectable rates in focused surveillance and contraindication have been obviously increasing. The incidence of occupational disease (mainly including acute occupational poisoning, pneumoconiosis, lead and benzene poisonings) is also going up. The incidence age of chronic occupational diseases tends to be younger accompanied with a shorter work history.</p>
