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>
