Correlates of depression and anxiety among homeless adults with latent tuberculosis infection.

Homeless persons have disproportionate rates of latent tuberculosis infection (LTBI). LTBI treatment can prevent and reduce active tuberculosis spread. We examined associations between mental health, social support, and perceptions of general health in 50 LTBI-positive, homeless adults enrolled in LTBI treatment. Depression and anxiety prevalence were 40% and 48%, respectively. Depression was negatively associated with general health, positive social interaction, and tangible, emotional/informational, and total social support, and positively associated with severe substance use (ps < 0.05). Anxiety was negatively associated with emotional/informational, tangible and total social support, and positively associated with severe substance use (ps < 0.05). Mental health services may help improve LTBI interventions.
