Abstract: Objective To investigate influenza A(H1N1) related knowledge and behaviors among university students and to provide information for influenza A(H1N1) epidemic prevention in campus.Methods A total of 873 students from three different majors of two univer sities in Guang zhou were recruited.A nonymous self admin istered questionnaire was used to collect data.Univ ariate and multivariate logistic regression model were used in the analysis.Results University students had some awareness of the transmission route and preventive measure of influenza A(H1N1)(39.2%-96.8%).Butmany of them did not have preventive behavior(23.9%-57.7%).After adjusting for significant background factors, students majoring in public health knewmore about influenza A(H1N1) related transmission route compared with those majoring in anthropology or social work(oddsratio=2.5-5.2, P < 0.01).There was no significant difference in influenzaA(H1N1)-related preventive behavior among students with different majors.Over 70% of the students reported that they had insufficient information to prevent influenza A(H1N1).Conclusion The condition of influenza A(H1N1) prevention in campus is far from requirment.Improvement in preventive perception and behavior is greatly needed among university students.
