  METHODS
  Investigations was conducted in resident and floating population in Yiwu city, Zhejiang province. A structured questionnaire was used to collect information on influence factors. Univariate and multivariate analyses were carried out using the Binary logistic regression. Findings : The study was conducted in Yiwu from June 2009 to September 2010. We recruited 844 participants，resident population 639（75.7%） and floating population 205（24.3%） who were preschool children. Multivariate analysis showed that Childbearing age (OR=0.93, 95%CI: 0.88-0.99), Asthma (OR=3.20, 95%CI: 1.60-6.45), Rickets (OR=5.30, 95%CI: 1.99-14.09), Food preference (OR=1.57, 95%CI: 1.02-2.43), Snack (OR=1.50, 95%CI: 1.07-2.07) were the influence factors for recurrent respiratory infections in resident preschool children. Infant feeding (OR=2.24, 95%CI: 1.31-3.81), Snack (OR=2.06, 95%CI: 1.07-3.98,), Trip mode (OR=2.77, 95%CI: 1.11-6.94) were the influence factors for recurrent respiratory infections in floating preschool children.
  
  
  CONCLUSIONS
  Public health measures against risk factors should be taken to protect against recurrent respiratory infections in resident and floating preschool children respectively.
