Suicide risk and alcohol and drug abuse in outpatients with HIV infection and Chagas disease

Abstract

Objective: To evaluate psychiatric comorbidities in outpatients receiving care for HIV and Chagas disease at Instituto de Pesquisa Clínica Evandro Chagas (IPEC), Fundação Oswaldo Cruz (Fiocruz), Rio de Janeiro, Brazil. Methods: Cross-sectional study with a consecutive sample of 125 patients referred to an outpatient psychiatric clinic from February to December 2010. The Mini International Neuropsychiatric Interview (MINI) was used. Factors associated with more frequent mental disorders were estimated by odds ratios (OR) with 95% confidence intervals (95%CI) by multiple logistic regression. Results: Seventy-six (60.8%) patients with HIV, 40 (32%) patients with Chagas disease, and nine (7.2%) patients with human T-lymphotropic virus were interviewed. The majority were women (64%), with up to 8 years of formal education (56%), and unemployed (81.6%). The median age was 49 years. Suicide risk (n=71) (56%), agoraphobia (n=65) (52%), major depressive episode (n=56) (44.8%), and alcohol/drug abuse (n=43) (34.4%) predominated, the latter being directly associated with lower family income (OR = 2.64; 95%CI 1.03-6.75) and HIV infection (OR = 5.24; 95%CI 1.56-17.61). Suicide risk was associated with non-white skin color (OR = 2.21; 95%CI 1.03-4.75), unemployment (OR = 2.72; 95%CI 1.01-7.34), and diagnosis of major depression (OR = 3.34; 95%CI 1.54-7.44). Conclusion: Measures targeting adverse socioeconomic conditions and psychiatric and psychological monitoring and care should be encouraged in this population, considering the association with abuse of alcohol/other psychoactive drugs and suicide risk.
