HIV, hepatitis C, and hepatitis B infections and associated risk behavior in injection drug users, Kabul, Afghanistan.

Behavior of injection drug users increases the risk for an HIV epidemic.

Prevalence of HIV, hepatitis B and hepatitis C and associated risk behaviours amongst injecting drug users in three Afghan cities

BACKGROUND HIV amongst injecting drug users (IDUs) has been described in Kabul but little data exists for other Afghan cities. We assessed HIV, hepatitis B virus (HBV), and C virus (HCV) prevalence and associated risk behaviours amongst IDUs in Hirat, Jalalabad, and Mazar-i-Sharif, Afghanistan. METHODS Consented participants reporting injecting drugs within the previous 6 months completed interviewer-administered questionnaires and testing for HIV, hepatitis C antibody (HCV Ab), and hepatitis B surface antigen (HBsAg). Logistic regression was used to determine characteristics associated with each infection. RESULTS Of 623 participants, most (98.7%) were male. Prevalence of HIV, HCV, and HBV was 1.8% (95% CI: 0.88-3.2), 36.0% (95% CI: 33-41), and 5.8% (95% CI: 3.9-7.6), respectively. All HIV cases and highest HCV prevalence were detected in Hirat; HBV prevalence was highest in Jalalabad. Amongst male IDUs, 62.9% had been imprisoned, of whom 17.2% (n=66) injected in prison. High risk behaviours were common; 30.2% reported needle sharing in the last 6 months, 23.1% reported sex with another male, and 50.4% reported paying females for sex. Behaviours varied significantly by site; generally, Hirat participants reported fewer sexual risk behaviours. Sex with other males was negatively associated with both HBV and HCV in multivariate logistic regression analysis; no injecting behaviours were associated with both HBV and HCV. CONCLUSIONS Whilst HIV prevalence is low, HCV prevalence and high risk behaviours were common in these populations. Regional variations should be considered in programming to prevent transmission of HIV and viral hepatitis amongst IDUs in Afghanistan.

Contraceptive Utilization and Pregnancy Termination Among Female Sex Workers in Afghanistan

BACKGROUND To determine the prevalence and correlates of prior pregnancy termination and unmet need for contraception among female sex workers (FSWs) in Afghanistan. METHODS FSWs in Jalalabad, Kabul, and Mazar-i-Sharif were recruited between June 2006 and December 2007 through outreach programs. Participants completed an interviewer-administered survey describing demographics, behaviors associated with risk of sexually transmitted infections (STIs) and unplanned pregnancy, and medical history. Correlates of prior pregnancy termination and current unmet need for contraception were assessed with logistic regression analysis, controlling for site. RESULTS Of 520 FSWs, most (82.3%) had been pregnant at least once (mean 4.9 ± 2.7, range 1-17), among whom unplanned pregnancy (36.9%) and termination (33.2%) were common. Jalalabad participants were more likely to report both prior unplanned pregnancy (60.6% vs. 48.3% in Kabul or 20.7% in Mazar, p < 0.001) and prior termination (54.9% vs. 31.8% in Kabul or 26.8% in Mazar, p < 0.001). Most FSWs (90.0%) stated pregnancy was not currently desirable, and 85.2% were using contraception. Unmet need for contraception (14.7% of participants) was positively associated with having sold sex outside their city of residence (adjusted odds ratio [AOR] 1.88, 95% confidence interval [CI] 1.28-2.77) and inversely associated with illicit drug use (AOR 0.41, 95% CI 0.31-0.53). CONCLUSIONS Although FSWs in Afghanistan report high rates of contraceptive use, unplanned pregnancy is common. Reproductive health services should be included in programming for FSWs to reduce unplanned pregnancies and to reduce HIV/STI risks.

HIV, hepatitis B, and hepatitis C prevalence and associated risk behaviors among female sex workers in three Afghan cities.

Objective:To assess prevalence of HIV, syphilis, and hepatitis B (HBV) and C virus (HCV) and associated risk behaviors among female sex workers (FSWs) in three Afghan cities. Design:Cross-sectional prevalence assessment. Methods:Consented FSWs from Jalalabad, Kabul, and Mazar-i-Sharif completed an interviewer-administered questionnaire, pretest and posttest counseling, and rapid and confirmatory testing for HIV, HCV, HBV, and syphilis. Logistic regression was used to detect correlates associated with HBV infection. Results:Of 520 participants, median age and age of initiating sex work were 29 and 23 years, respectively, and the median number of monthly clients was 12. Few FSWs reported ever having used illicit drugs (6.9%) or alcohol (4.7%). Demographic and risk behaviors varied significantly by enrollment site, with Kabul FSWs more likely to report sexually transmitted infection symptoms, longer sex work duration, and sex work in other cities. Prevalence of HIV was 0.19%, HCV was 1.92%, and HBV was 6.54%, with no cases of syphilis detected. HBV was independently associated with at least 12 clients monthly [adjusted odds ratio (AOR) = 3.15, 95% confidence interval (CI) 1.38–7.17], ever using alcohol (AOR = 2.61, 95%CI 1.45–4.69), anal sex (AOR = 2.42, 95%CI 1.15–5.08), and having children (AOR = 2.12, 95%CI 1.72–2.63) in site-controlled multivariable analysis. Conclusion:Although prevalence of HIV, HCV, and syphilis is currently low in these three Afghan cities, risky sexual practices were common and associated with HBV. Programming inclusive of voluntary testing for HIV, viral hepatitis, and sexually transmitted infections, hepatitis vaccination, substance abuse prevention, and condom promotion for both FSWs and clients should be pursued in Afghanistan.

High HIV prevalence and risk factors among injection drug users in Tashkent Uzbekistan 2003-2004.

OBJECTIVES To determine HIV prevalence and potential associations with sociodemographic and behavioral factors among injection drug users (IDUs) in Tashkent, Uzbekistan. METHODS Subjects in this cross-sectional study provided sociodemographic and risk behavior data and were tested for HIV antibody with a saliva-based enzyme-linked immunosorbent assay (ELISA), followed by saliva-based Western blot confirmation. RESULTS Among the 701 IDU subjects enrolled, 209 (29.8%) were diagnosed with HIV infection, HIV infection was more likely among those unemployed (adjusted odds ratio [AOR]=1.47); whose first drug of abuse was heroin (AOR=2.21) or opium poppy extract (AOR=1.61); with a prior history of hepatitis (AOR=1.39); and those who reported never using condoms (AOR=1.65). Independent risk factors associated with HIV infection were heroin as the first illicit drug of abuse, prior hepatitis, lack of condom use, and unemployment. CONCLUSIONS Heroin use, sexual transmission, and high unemployment seem to play important roles in HIV transmission. Implementation of effective harm reduction strategies is critical to control the expansion of the HIV epidemic in this country as well as in this region.

Association between expatriation and HIV awareness and knowledge among injecting drug users in Kabul, Afghanistan: A cross-sectional comparison of former refugees to those remaining during conflict

BackgroundLittle is known about human immunodeficiency virus (HIV) awareness among Afghan injecting drug users (IDUs), many of whom initiated injecting as refugees. We explored whether differences in HIV awareness and knowledge exist between Afghan IDUs who were refugees compared to those never having left Afghanistan.MethodsA convenience sample of IDUs in Kabul, Afghanistan was recruited into a cross-sectional study through street outreach over a one year period beginning in 2005. Participants completed an interviewer-administered questionnaire and underwent voluntary counseling and testing for HIV, syphilis, hepatitis B surface antigen, and hepatitis C antibody. Differences in HIV awareness and specific HIV knowledge between IDU who lived outside the country in the last decade versus those who had not were assessed with logistic regression.ResultsOf 464 IDUs, 463 (99%) were male; median age and age at first injection were 29 and 25 years, respectively. Most (86.4%) had lived or worked outside the country in the past ten years. Awareness of HIV was reported by 46.1%; those having been outside the country in the last decade were significantly more likely to have heard of HIV (48.3% vs. 31.7%; OR = 2.00, 95% CI: 1.14 – 3.53). However, of those aware of HIV, only 38.3% could name three correct transmission routes; specific HIV knowledge was not significantly associated with residence outside the country.ConclusionAccurate HIV knowledge among Afghan IDUs is low, though former refugees had greater HIV awareness. Reported high-risk injecting behavior was not significantly different between IDU that were refugees and those that did not leave the country, indicating that all Afghan IDU should receive targeted prevention programming.

Prevalence and correlates of risky sexual behaviors among injection drug users in Tashkent, Uzbekistan

Abstract The objective of this paper is to describe prevalence and correlates of sexual risk behaviors among injection drug users (IDUs) in Tashkent, Uzbekistan. Participants in this cross-sectional study completed a questionnaire detailing sociodemographic, medical and drug and sexual risk behaviors and HIV antibody testing. Of 701 IDUs surveyed, only 20.5% reported consistent condom use, which was more likely for women. Prior sexually-transmitted infection (STI) diagnosis was reported by 36.2% of participants and was associated with early (≤18 years) drug initiation, group drug use, being older, higher educational level, marriage, needle sharing, multiple sex partners in the preceding month and daily injection use. Having multiple partners in the preceding month was common (29.71%) and related to employment, consistent condom use with regular partners and STI self-treatment in multivariate logistic regression. Participants with a history of sharing needles were less likely to have had multiple partners in the previous month. Risky sexual behaviors are common and interrelated with risky injection habits among IDUs in Tashkent, Uzbekistan, representing a continued threat of infection with HIV and other blood-borne agents.

Prevalence and correlates of human immunodeficiency virus infection among female sex workers in Tashkent Uzbekistan.

Objectives/Goal: To assess prevalence of and correlates to human immunodeficiency virus (HIV) infection among female sex workers in Tashkent, Uzbekistan. Study Design: Women participating in this cross-sectional study completed a questionnaire and HIV testing between April 2003 and March 2004. Logistic regression analyses determined correlation of variables to HIV infection. Results: Of 448 women, 10% (45) were HIV infected, which was associated with ever injecting drugs (AOR = 20.20; 95% confidence interval [CI], 7.69–53.07), street-based sex work (AOR = 4.52; 95% CI, 1.84–11.12), exchanging sex for drugs (AOR = 4.74; 95% CI, 1.84–12.18), and more sexually transmitted infection treatments in the preceding 3 months (AOR = 2.43; 95% CI, 1.14–5.17). Conclusions: Although injection drug use is the strongest correlate to HIV infection, sexual risk behaviors are independently related and should receive focus in prevention efforts targeted to this population.

Implications of hepatitis C viremia vs. antibody alone on transmission among male injecting drug users in three Afghan cities

OBJECTIVES To assess differences between injecting drug users (IDUs) with hepatitis C virus (HCV) viremia and IDUs with HCV antibody (Ab) or no evidence of prior infection in three Afghan cities. METHODS IDUs in Hirat, Jalalabad, and Mazar-i-Sharif completed questionnaires and rapid testing for blood-borne infections including HCV Ab. HCV Ab was confirmed with a recombinant immunoblot assay (RIBA); RIBA-positive specimens underwent reverse transcriptase polymerase chain reaction (RT-PCR) for HCV. Risk behaviors associated with viremia were assessed with site-controlled ordinal regression analysis. RESULTS Of 609 participants, 223 (36.6%) had confirmed HCV Ab. Of 221 with serum available for PCR evaluation, 127 (57.5%) were viremic. HCV viremia prevalence did not differ by site (range 41.7-59.1%; p=0.52). Among all IDUs, in age and site-controlled ordinal regression analysis, HCV was independently associated with HIV co-infection (adjusted odds ratio (AOR) 7.16, 95% confidence interval (CI) 4.41-11.64), prior addiction treatment (AOR 1.95, 95% CI 1.57-2.42), ever aspirating and re-injecting blood (AOR 1.62, 95% CI 1.18-2.23), prior incarceration (AOR 1.60, 95% CI 1.04-2.45), and sharing injecting equipment in the last 6 months (AOR 1.35, 95% CI 1.02-1.80). CONCLUSION HCV viremia was present in many participants with prior HCV infection and was associated with some injecting risk behaviors, indicating a substantial risk for transmission. Current harm reduction programs should aim to improve HCV awareness and prevention among IDUs in Afghanistan as a matter of urgency.

HIV awareness and condom use among female sex workers in Afghanistan: implications for intervention

Abstract There is little information about HIV awareness or condom use among female sex workers (FSWs) in Afghanistan. The purpose of this cross-sectional study was to assess HIV awareness, knowledge, and condom use among FSWs in three Afghan cities. FSWs residing in Jalalabad, Kabul, and Mazar-i-Sharif were recruited through outreach programs and completed an interviewer-administered questionnaire and rapid tests for hepatitis B surface antigen, HIV, syphilis, and hepatitis C virus. Logistic regression identified factors associated with HIV awareness, comprehensive HIV knowledge (knowledge that HIV cannot be detected by sight, that condoms prevent HIV, and rejection of local misconceptions about HIV transmission), and consistent condom use (use with every sex act) with clients in the last six months. Of 520 participants, 76.9% had no formal education and 37.7% lived outside Afghanistan in the last five years. Nearly half (44.2%) were aware of HIV but, of these, only 17.4% (N=40) had comprehensive HIV knowledge. There were significant differences by site; FSWs in Jalalabad were more likely to be aware of HIV but FSWs in Kabul were more likely to have correct HIV knowledge and use condoms consistently with clients. Consistent client condom use was reported by 11.5% (N=60) and was independently associated with having more clients per month (AOR=1.99, 95% CI: 1.04–3.81). In conclusion, comprehensive HIV knowledge and consistent condom use with clients are low among Afghan FSWs in these cities. Efforts to reach this population should focus on relaying accurate information and expanding condom use with clients.
