目的对桐乡市湖羊交易市场相关重点职业人群开展布鲁菌病感染现状调查,分析流行特征及危险因素,为进一步制定布鲁菌病防治策略提供参考依据。方法对入职半年及以上的相关从业人员进行血清学检测和行为问卷调查,并对数据进行统计学分析。结果共检测从业人员1 355人,阳性41人,阳性率为3.03%。感染者中以关节酸痛、低热、乏力为主要体症;不同性别、年龄、工种、工龄及地区的感染率差异均有统计学意义(P<0.05)。经单因素非条件Logistic回归分析,危险因素有男性(OR=0.391)、31岁~59岁(OR=0.252)、加工工种(OR=3.201)、有流产子畜接触史(OR=3.523);经多种因素分析,与布鲁菌病感染可能相关的危险因素有流产子畜接触史(OR=5.178),而操作有保护措施(OR=0.151)是其保护因素。结论建议加强布鲁菌病职业重点人群的健康教育,提高职业人群保护意识,降低布鲁菌病发病水平。

The infection rates among different sex, age, type of work, length of service and area were all statistically significant (P <0.05). According to the univariate non - conditional logistic regression analysis, the risk factors were male (OR = 0.391), age 31-59 (OR = 0.252) According to various factors, the risk factors associated with Brucellosis infection are abortion history (OR = 5.178), and protective measures (OR = 0.151) are the protective factors.
