Influencing factors of cognition on hepatitis B among floating population in Daxing district of Beijing

ObjectiveTo analyze status and influencing factors of cognition on hepatitis B among floating people in Daxing district of Beijing and to provide scientific basis for hepatitis B prevention and control in the population.MethodsWe randomly selected 973 floating people and surveyed on their demographic characteristics and cognition on hepatitis B with an enclosed structure interview between January 2011 to April 2012.We used STATA 12.0,variance analysis,Cochran Armitage trend test and multivariate liner regression in data analyses.ResultsMost of the participants had knowledge about hepatitis B (91.06%,886/973), hepatitis B vaccine(83.14%,809/973),and effective prevention of the disease(89.72%,873/973).Univariate analysis and Cochran Armitage trend test showed that the average score of the cognition on hepatitis B declined gradually with the increment of age and increased with the upgrade of education level of the participants.The participants with the education below primary school,low income,and being peasant had lower score of the cognition,while the participants with hepatitis B vaccination history showed higher scores compared to those without the vaccination history(P<0.05).Multivariate liner regression analysis showed that the cognition score was positively correlated with education level(P<0.05);the participants with hepatitis B vaccination history had better cognition than those without the history(P<0.05);and education level had most strong impact on the cognition on hepatitis B.ConclusionEducation level and whether having received hepatitis B vaccination are major influencing factors of cognition on hepatitis B among floating population.
