目的 揭示肉联厂从业人员感染弓形虫的行为危险模式。方法 在杭州市肉联厂采集从业人员标本 ,用酶联免疫吸附试验检测弓形虫循环抗原、IgG和IgM抗体 ;行为测量采用基于行为推理理论的问卷调查。以行为推理理论假设感染的行为危险模式。结构由一个测量行为变量关系的模型和一个反映行为变量彼此间关系的行为变量模型构成。用因子分析结合通径分析的方法对这一结构中的各参数进行估计。结果 共完成 30 2人的调查 ,回收率 95 .87%。弓形虫感染率 19.2 0 %,近期感染指标循环抗原阳性率 15 .89%,IgM抗体阳性率2 .32 %,既往感染指标IgG抗体阳性率5 .6 3%,循环抗原与IgG、IgM抗体同时阳性的占1.32 %,循环抗原与IgG抗体同时阳性的占 2 .6 5 %,循环抗原与IgM抗体同时阳性的占1.99%。弓形虫感染与难产及接触生猪、体液、内脏有关 ,与流产无关。因子分析结果显示除了行为态度和行为后果评价外 ,其他行为的内在可信度较好 (克劳巴赫系数大于0 .7) ,这些测量项目能很好地解释行为变量。通径分析显示 ,两个结构均显著独立贡献于防护行为 ,防护行为与弓形虫感染的发生有关 ;行为因素与其他因素对弓形虫感染发生的贡献率约各占5 0 .0 0 %。行为信念在预测防护行为方面比主观规范更加重要。结论 用行为推理理论基本上
Objective To reveal the behavioral hazard mode of Toxoplasma gondii infection in practitioners in RCHE. Methods The specimens of practitioners were collected from meat factory in Hangzhou and Toxoplasma gondii antigens, IgG and IgM antibodies were detected by enzyme-linked immunosorbent assay (ELISA). The behavioral measurement was based on behavioral reasoning. Behavioral risk model of hypothetical infection with behavioral reasoning theory. The structure consists of a model that measures the relationship between behavioral variables and a behavioral variable model that reflects the relationship of behavioral variables to each other. The factor analysis combined with path analysis method to estimate the parameters in this structure. Results A total of 30 2 people completed the survey, the recovery rate of 95.87%. The infection rate of Toxoplasma gondii was 19.2%, the positive rate of circulating antigen in recent infection was 15.89%, the positive rate of IgM antibody was 2.32%, the positive rate of IgG antibody in past infection was 5.36%, while the circulating antigen and IgG, IgM antibody Positive accounted for 1.32%, circulating antigen and IgG antibodies positive accounted for 2.56%, circulating antigen and IgM antibodies simultaneously accounted for 1.99%. Toxoplasma gondii infection and dystocia and exposure to live pigs, body fluids, internal organs, has nothing to do with abortion. Factor analysis revealed that other behaviors, except for behavioral attitudes and behavioral consequences, were more plausible (the Crawlbach coefficient was greater than 0.7) and explained well the behavioral variables. Path analysis showed that both structures contributed significantly to protective behavior independently, and protective behavior was related to the occurrence of Toxoplasma gondii infection. The contribution rate of behavioral and other factors to Toxoplasma gondii infection was about 50.0%. Behavioral beliefs are more important than subjective norms in predicting protective behavior. Conclusions Using behavioral reasoning theory is basically
