Prevalence of human immunodeficiency virus infection, risk behavior, and HIV knowledge among tuberculosis patients in Afghanistan.

OBJECTIVES/GOAL: To assess prevalence and correlates of human immunodeficiency virus (HIV) infection, risk factors, and HIV knowledge among tuberculosis patients in Afghanistan.

STUDY

DESIGN

Adult participants undergoing treatment for tuberculosis in this cross-sectional study completed a questionnaire and HIV testing between November 2005 and February 2006. Prevalence of HIV and high-risk behaviors were calculated, with correlates of high-risk behavior and relevant knowledge assessed.

RESULTS

Of 1163 participants, 2 (0.2%, 95% CI: 0.0-0.6) were HIV-infected. Known risk factors for HIV infection, such as paying women for sex or male to male sexual contact, were rarely reported, though receipt of injections from a nonmedical provider was common (38%). Symptoms suspicious for sexually transmitted infection were reported by 5% of the population and were significantly associated with young (<26 years) age (OR: 3.2, 95% CI: 1.7-6.0). Relatively, a few participants had ever heard of HIV (23%) or condoms (25%). Condom use was significantly more frequent among those 26 and older (OR: 2.9, 95% CI: 1.7-5.2) and among male participants (OR: 1.5, 95% CI: 1.0-2.2).

CONCLUSIONS

HIV prevalence among tuberculosis patients in Afghanistan is currently quite low. However, lack of knowledge of HIV and engaging in high-risk practices, particularly regarding health, make this group vulnerable. Health education sessions regarding HIV, sexually transmitted infection, and blood-borne infections should be implemented for tuberculosis patients during the treatment course.
