目的调查浙江省职业人群布鲁氏菌病(布病)感染状况及危险因素,为制定科学防治策略提供依据。方法2015年10月至2016年3月,选择浙江省从事牛羊饲养、运输、交易、屠宰、兽医、皮毛乳肉加工及海洋捕捞等布病重点职业人群,采集其全血5 ml,分离血清,采用RBPT和SAT进行实验室血清学检测,采用病例对照研究,利用多因素Logistic回归进行危险因素分析。结果采集重点职业人员全血3 410份,其中105份血清SAT阳性,感染率为3.08%。男女性感染率分别为3.10%和3.02%,差异无统计学意义(χ~2=0.010,P=0.970)。多因素Logistic回归分析发现,从不戴手套、手部有伤口或皲裂与布病发病有关。结论从不戴手套、手部有伤口或皲裂是目前浙江省布病发病的高危因素;应开展健康教育和干预措施,提高从业人员的防护意识。
Objective To investigate the prevalence and risk factors of brucellosis (IBD) among occupational population in Zhejiang province, and to provide basis for formulating scientific prevention and control strategies. Methods From October 2015 to March 2016, Zhejiang Province was selected to focus on the occupational diseases such as cattle and sheep breeding, transportation, trading, slaughtering, veterinary medicine, fur milk processing and marine fishing. The whole blood was collected 5 ml, serum, Laboratory RBT and SAT serological tests, case-control studies, the use of multivariate logistic regression analysis of risk factors. Results A total of 3 410 whole blood samples were collected from key professionals, of whom 105 were positive for SAT and 3.08% were seropositive. The infection rates of men and women were 3.10% and 3.02% respectively, with no significant difference (χ ~ 2 = 0.010, P = 0.970). Multivariate logistic regression analysis found that never wear gloves, hand wounds or chapped with the incidence of brucellosis. Conclusion Never wear gloves, wounds or chapped hands is the risk factor for the incidence of brucellosis in Zhejiang Province; health education and interventions should be carried out to improve the protection awareness of practitioners.
