Knowledge, attitudes, and practices associated with avian influenza along the live chicken market chains in Eastern China: A cross‐sectional survey in Shanghai, Anhui, and Jiangsu. Issue 4 (10th April 2019) - Zhou, Xiaoyan
Summary: The avian influenza (AI) virus of the H7N9 subtype emerged in China in 2013. Live bird markets (LBMs) selling live meat chickens were indicated to present a high‐risk of the virus dissemination. This study aimed to quantify the level of knowledge, attitudes, and practices (KAP) on AI and to measure the associated risk factors among different actors along the live chicken market chain within H7N9‐affected Eastern provinces in China. A cross‐sectional survey was conducted in these provinces from June to July 2014. Structured questionnaires about KAP on AI were delivered to chicken farmers, chicken vendors, and consumers in LBMs. Multivariable generalized least squares regression models were developed to identify predictors of KAP scores among different actors. Our results indicate that KAP scores of chicken farmers were generally higher than those of chicken vendors. Chicken farmers who worked for more than 15 years had significantly lower total KAP scores than those who worked for less than 6 years. Chicken farmers who worked more than 15 hrs in a day had significantly lower attitude scores than those who worked less than 6 hrs. For chicken vendors, females and individuals > 35 years old had significantly lower knowledge scores compared to the reference categories. Practice scores were significantly higher in female vendors and those vendors who also conducted slaughter compared to males and vendors who did not conduct slaughter. Consumers who bought chicken at least once every month had better risk awareness compared to those who bought chicken at least once every week. In addition, female consumers had significantly better practice scores than male consumers. In conclusion, risk‐based health promotion interventions should be developed and implemented by animal health agencies (targeting farmers and vendors) and public health agencies (targeting frequent and male consumers) to prevent transmission of H7N9 along the market chain in China.
