Background Homeless people are at high risk of HIV and tuberculosis (TB) infection due to living in poor sanitary conditions and practicing high-risk behavior. The aim of this study is to assess the knowledge, attitude, and practice (KAP) of homeless people in Tehran regarding TB and HIV.   Methods Using a convenience sampling, we performed a cross-sectional study on homeless people in Tehran from June to August ۲۰۱۲. Participants aged ۱۸-۶۰ years having at least ۱۰ days of homelessness in the preceding month to the study period were included. All required data were collected through face-to-face interviews conducted using a researcherdesigned questionnaire. Each score in KAP of TB and HIV was separately divided by the maximum score and multiplied by ۱۰۰ to attain percentage scores. The mean scores were compared using analysis of variance (ANOVA) and student’s t test. A Tukey test was used for post hoc analysis and two-by-two comparisons.   Results In this study, ۵۹۳ participants consisting of ۵۱۳ men and ۸۰ women were included. The mean age of the participants was ۴۱.۷۴ ± ۰.۴۵ years. Moreover, the total mean score of KAP toward HIV was ۷۹.۲۴ (۹۵% CI: ۷۷.۳۶, ۸۱.۱۲), ۵۷.۱۳ (۹۵% CI: ۵۵.۱۲, ۵۹.۱۴), and ۲۱.۱۴ (۹۵% CI: ۱۸.۳۵, ۲۳.۹۳), respectively. The total mean score of knowledge and practice regarding TB was ۶۲.۰۴ (۹۵% CI: ۵۹.۹۴, ۶۴.۱۴) and ۴۲.۵۷ (۹۵% CI: ۴۰.۳۶, ۴۴.۷۸), respectively.    Conclusion Although a relatively acceptable knowledge was detected in this high-risk population, practices regarding TB and HIV showed some weaknesses. Developing special programs to improve the healthy behavior of this population is highly recommended.
