HCV Infection Prevalence Lower Than Expected among 18–40-Year-Old Injection Drug Users in San Diego, CA

Abstract: San Diego, California shares the world's busiest land border crossing with Tijuana, Mexico-a city where 95 % of injection drug users (IDUs) test hepatitis C virus (HCV) antibody-positive. Yet, little is known about the prevalence and risk behaviors for HCVamong IDUs in San Diego. In 2009-2010 IDUs in San Diego County completed a risk assessment interview and serologic testing for HCV and HIV infection. Recruitment involved respondent-driven sampling, venue-based sampling at a syringe exchange program, and conv… Show more

“…Although the prevalence was lower among San Diego PWID compared with Tijuana PWID in the present study (19.8%), prevalence appears to have increased compared with results of an earlier study conducted in 2009-2010 (7.2%) (Garfein et al, 2013). This increase among PWID in San Diego should be interpreted cautiously, however, because the earlier cohort was restricted to PWID ages 18-40 years but open to PWID who had injected in the past 6 months (compared with in the previous month for the present study).…”

“…Injection drug use, a large red-light district (zona roja) attracting sex tourism, and high levels of social and economic disparities have contributed to a localized HIV epidemic in Tijuana. Given the substantial bidirectional traffic of people and goods in this region, there are significant implications for cross-border spread of unsafe injecting practices that heighten the risk of blood-borne infections, including HIV and hepatitis C. Although PWID are known to inject both heroin and methamphetamine (Darke & Hall, 1995;Garfein et al, 2013;Meacham et al, 2015;Roth et al, 2015;Rusch et al, 2009), less is known about the prevalence of and risks associated with mixed or co-injection of this depressant-stimulant combination.The present analysis examined the prevalence and correlates of heroin-methamphetamine co-injection among PWID in San Diego, California, and Tijuana, Baja California. Given the production of methamphetamine in Mexico and the limited access to healthcare and drug treatment services, we hypothesized that past-6-month prevalence of heroinmethamphetamine co-injection would be higher among PWID in Tijuana.…”

“…36 To reduce the recall and socially desirable bias, drug and sexual behaviors were determined shortly (e.g., 3 months) prior to the interview. 37 Third, data on comorbidities such as hepatitis B or hepatitis C infection, alcoholism, hypertension, diabetes mellitus, and liver/renal diseases were not available for this study. Studies about the association between medical comorbidities and HRQOL in IDUs are lacking 10,11 ; future studies are needed.…”

“…PWID between ages 18-40 years-old in San Diego, California were recruited to participate in the Study to Assess Hepatitis C Risk (STAHR) between March 2009 and June 2010 [18]. Sociodemographic, drug use, behavioral, and access to care factors were assessed using audio computer assisted self-interviewing (ACASI) technology.…”
