Objective: To study the willingness and influence factors related to "centralized slaughtering, fresh poultry listing and marketing" strategy, among the household chefs, and provide reference for government to adjust and optimize the strategy on avian influenza prevention. Methods: According to the geographical characteristics and regional functions, 6 'monitoring stations' were selected from 12 residential districts of Guangzhou, respectively. Another 21 meat markets which selling live poultry, were selected in each station and 5 household chefs of each market were invited to attend a face to face interview. Basic information, personal cognitive, willingness and influencing factors to the policy were under study. Univariate and multivariate logistic regression methods were used. Results: A total of 664 household chefs underwent the survey and results showed that the rate of support to the "centralized slaughtering, fresh poultry listing and marketing" strategy was 44.6% (296/664). Results from the multi-factor logistic regression showed that those household chefs who were males (OR=1.618, 95% CI: 1.156-2.264, P=0.005), having received higher education (OR=1.814, 95% CI: 1.296-2.539, P=0.001), or believing that the existence of live poultry stalls was related to the transmission of avian influenza (OR=1.918, 95% CI: 1.341-2.743, P<0.001) were factors at higher risk. These household chefs also intended to avoid the use of live poultry stalls (OR=1.666, 95%CI: 1.203-2.309, P=0.002) and accept the "centralized slaughtering, fresh poultry listing and marketing" strategy. Conclusion: Detailed study on this subject and, setting up pilot project in some areas as well as prioritizing the education programs for household chefs seemed helpful to the implementation of the 'freezing-fresh poultry' policy.
目的： 了解广州市家庭主厨人员对全面实施"集中屠宰，生鲜上市"措施的接受意愿及影响因素，为禽流感防控策略的调整与优化提供参考。 方法： 在2017－2018年广州市禽流感疫情休市期间按照地理特征和区域选取6个行政区，每个区选取21个有活禽交易的肉菜市场，每个市场随机选取5名家庭主厨人员进行调查。收集研究对象人口学特征、个人认知、政策接受意愿等相关因素。应用单因素和多因素logistic回归分析居民对"集中屠宰，生鲜上市"措施接受意愿的影响因素。 结果： 共调查家庭主厨664人，受访者对实施"集中屠宰，生鲜上市"措施的支持率为44.6%（296/664）。多因素logistic回归分析显示，男性、大专及以上学历、认为肉菜市场活禽档口的存在与禽流感传播间有关系、市场购物期间有意避开活禽档口的人群更容易接受"集中屠宰，生鲜上市"措施，OR值及95% CI分别为1.618（1.156~2.264）、1.814（1.296~2.539）、1.918（1.341~2.743）和1.666（1.203~2.309），P值分别为0.005、0.001、<0.001和0.002。 结论： 充分调研、局部试点以及加强女性、学历低者的宣传教育有助于"集中屠宰，生鲜上市"措施顺利实施。.
