Methods A questionnaire survey was conducted at HIV treatment clinic from the city of Nanning,Baise and Qinzhou by face-to-face conversations. The respondents were divided into 3 groups,including single HIV-1-infected patients( HIV group),single TB-infected patients( TB group) and HIV/TB co-infected patients( HIV/TB group). The questionnaire was designed in term of general demographic characteristics and factors that contribute to HIV and TB infection. By comparing HIV / TB group and other groups respectively,univariate and multivariate logistic regression were used to analyze the factors associated with HIV / TB co-infection. Results 174 respondents were recruited,including 83( 47. 7%) of single HIV-1 infection,56( 32. 2%) of single TB infection,and 35( 20. 1%) including of HIV / TB co-infection. Compared with HIV group,HIV / TB co-infection was statistically significantly associated with knowledge of the policy of free TB treatment( OR = 2. 85,95% CI: 1. 03-7. 85),and having received HIV / AIDS counseling service( OR = 0. 17,95% CI: 0. 06-0. 49). Compared with TB group, HIV / TB co-infection was significantly associated with living in Qingzhou,Basise Areas( OR = 3. 44,95% CI: 1. 26-9. 42),and knowledge of HIV / AIDS mostly from hospital consulting( OR = 3. 68,95% CI: 1. 28-10. 56). Conclusions The social public health education of both AIDS and TB should be improved. The way of HIV / TB transmission via blood transfusion should be kept in heightened alertness.
