Tuberculosis Knowledge, Attitudes, and Beliefs in Foreign-born and US-born Patients with Latent Tuberculosis Infection

Foreign-born individuals comprise the majority of patients treated for latent tuberculosis infection (LTBI) in the US. It is important to understand this population's tuberculosis-related knowledge, attitudes, and beliefs (KAB) as they may affect treatment acceptance and completion. KAB in 84 US-born and 167 foreign-born LTBI patients enrolled in a clinical trial assessing treatment completion at an urban public hospital were assessed at baseline. Demographic and substance use information was also collected. Results: Of 251 participants, 66.5% were foreign-born. While misconceptions existed among both US and foreign-born regarding transmission and contagiousness of LTBI, overall knowledge scores did not differ significantly between groups. With respect to attitudinal factors, foreign-born participants were less likely to acknowledge that they had LTBI and felt more "protected" from developing TB. Improved understanding of foreign-born patients' KAB may contribute to the reduction of barriers to treatment and improved outcomes.
