The purpose of this study was to examine predictors of screening results for depressive symptoms in a Los Angeles homeless population with latent tuberculosis (TB). Four hundred and fifteen homeless adults participating in a nurse case managed intervention were included in this analysis. Logistic regression results indicated that those who reported a physical health limitation, multiple sex partners, daily drug use, alcohol dependence, or not having completed high school, were more likely to screen positive. Social support from non-drug users was protective. Given the importance of adherence to TB treatment regimens, the high prevalence of a positive screening for depressive symptoms in the homeless and the potential for depression to reduce adherence rates, routine screening and treatment for depression in high risk homeless adults being treated for TB may be warranted.

Findings are presented for a cross-sectional study of serological markers of hepatitis B virus (HBV) infection in an underserved population—impoverished veterans of the US armed forces in a Veterans Administration (VA) residential program in the US. We examine the demographic, background, and risk factors associated with HBV infection in this high-risk population. This paper presents a secondary analysis of cross-sectional survey and clinical data for 370 male veterans who were residents of a domiciliary care program for homeless veterans in Los Angeles, using χ2, Fisher's Exact, and logistic regression analysis. About one-third (30.8%) of the sample tested positive for current or past HBV infection (ie, seropositive for either the HBV core antibody or surface antigen). After multivariate analysis, rates of HBV were significantly higher among veterans who were older, non-white, or who had a history of regular heroin use (a proxy measure for injection drug use), drug overdose, or drug detoxification treatment. The rate of current or past HBV infection among veterans in this sample (30.8%) was high compared to an estimated 5% to 8% of the general US population. Also, 3% of the sample were currently infected with HBV. Strategies for intervention include broader screening, immunization, and treatment interventions with this high-risk group.Public Health (2001) 115, 286–291. [ABSTRACT FROM AUTHOR]
