摘要

Objective: To identify and compare risk factors for recurrent respiratory infections in preschool children between resident and floating population in Yiwu, China.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.Conclusion: Public health measures against risk factors should be taken to protect against recurrent respiratory infections in resident and floating preschool children respectively.Key Words: Recurrent Respiratory Infection, Risk Factor, Child, Floating Population
