Abstract:
Objective To investigate human exposure to live poultry (poultry feeding and purchasing) in the residents in Beijing and related factors during the second wave of avian influenza A (H7N9) epidemic during 2013-2014, and provide scientific evidence for avian influenza prevention and control. Methods A total of 7366 adults aged ≥18 years were selected through multi-stage stratified sampling in Beijing for a questionnaire survey. Logistic regression model was used to analyze the influence factors of human exposure to live poultry. Results The live poultry feeding rate and live poultry purchasing rate in residents in Beijing in the past year were 5.3%(95%CI:4.8%-5.8%) and 6.0% (95%CI: 5.5%-6.5%) respectively. Logistic regression analysis indicated that lower educational level of primary school and below, (OR=1.82, 95%CI:1.22-2.72);being farmer (OR=2.49, 95%CI:1.89-3.29) or being unemployed (OR=1.65, 95%CI:1.08-2.52);being non local resident (OR=1.54, 95%CI:1.10-2.16);living in suburban area (OR=2.36, 95%CI:1.77-3.16);having one child (OR=1.76, 95%CI: 1.42-2.17) or ≥2 children (OR=2.15, 95%CI: 1.43-3.22) in the family were the risk factors associated with feeding poultry compared with higher educational level of college and above, being employed, being local resident, living in urban area and having no child. And being farmer (OR=1.61, 95%CI:1.27-2.02);being non local resident (OR=1.76, 95%CI:1.31-2.35);living in suburban area (OR=2.05, 95%CI:1.61-2.61);having one child (OR=1.24, 95%CI:1.02-1.52) or ≥2 children (OR=1.78, 95%CI: 1.21-2.63) were the risk factors for purchasing live poultry. Conclusion Some residents living in Beijing still have exposure to live poultry, and targeted measures should be taken to reduce the exposure to poultry.
