“…[5] Furthermore, our studies that documented higher HIV prevalence in Tijuana pregnant residents may reflect an emerging phenomenon. [2,3] Our study suggests that 32% of pregnant women who give birth at Tijuana General Hospital have recently migrated from other Mexican cities or states and their HIV seroprevalence is similar to the pregnant women who are longterm Tijuana residents. However, Tijuana residents were significantly more likely to engage in high-risk behavior for HIV acquisition.…”

“…Beginning in 1997, the University of California San Diego Mother, Child and Adolescent HIV Program established a collaboration with pediatricians and obstetricians who provide HIV care in Tijuana, Baja California, Mexico. [2] We recently conducted a cross-sectional study to evaluate the feasibility and acceptance of counseling and rapid HIV testing during pregnancy at Tijuana General Hospital. [3] Part of our study focused on internal migration patterns and risk factors for HIV acquisition.…”

“…In addition, prenatal HIV testing and treatment to prevent maternal-fetal transmission was not fully implemented until 2003. 8,9 During 2003 and 2004, we conducted a study to examine the acceptance of HIV counseling and rapid testing using Determine 1 HIV-1/2 during pregnancy and at delivery. The acceptance rate of rapid HIV testing during prenatal care and at delivery was *95%.…”

This study evaluated an obstetrical program using rapid HIV testing for the prevention of mother-to-child HIV transmission (MTCT) in Baja California, Mexico. Between 2003 and 2005, 45 women in labor and 17 prenatal care women were HIV infected. Among labor patients, 14 (31%) delivered by cesarean section compared with 17 (100%) prenatal care patients (P < .001). Intravenous maternal zidovudine (ZDV) and infant oral ZDV were more frequently administered in prenatal care compared to labor patients: 94% versus 33% (P < .001) and 100% versus 79% (P < .001), respectively. All prenatal care women received combination therapy. All 10 HIV-infected infants were in the labor group, resulting in a MTCT rate of 23% (95% confidence interval [CI] 9.5-34.8) compared to 0% (95% CI 0-1.8; P < .001) among the prenatal care group. Five (50%) of the HIV-infected infants had an AIDS diagnosis and 2 (20%) died within 18 months of birth. Women diagnosed during labor had a high HIV MTCT and poor postnatal outcome.

“…Although injection drug use appears to have played only a minor role in the epidemic on a country-wide level,14 injection drug use appears to be increasingly important as a risk factor for HIV infection in some Mexican cities bordering the U.S. Viani et al15 noted that the prevalence of HIV among pregnant women giving birth at Tijuana General Hospital rose from 0.29% in 1998 to 1.02% in 2001 and, in a subsequent study, showed that pregnant HIV-infected women were more likely to either inject drugs or to have a spouse/partner who injected drugs 16. In 2002, Valdez et al17 reported that 21% of female sex workers in Ciudad (Cd.)…”

Respondent-Driven Sampling of Injection Drug Users in Two U.S.–Mexico Border Cities: Recruitment Dynamics and Impact on Estimates of HIV and Syphilis Prevalence

et al. 2006

Respondent-driven sampling (RDS), a chain referral sampling approach, is increasingly used to recruit participants from hard-to-reach populations, such as injection drug users (IDUs). Using RDS, we recruited IDUs in Tijuana and Ciudad (Cd.) Juá rez, two Mexican cities bordering San Diego, CA and El Paso, TX, respectively, and compared recruitment dynamics, reported network size, and estimates of HIV and syphilis prevalence. Between February and April 2005, we used RDS to recruit IDUs in Tijuana (15 seeds, 207 recruits) and Cd. Juá rez (9 seeds, 197 recruits), Mexico for a cross-sectional study of behavioral and contextual factors associated with HIV, HCV and syphilis infections. All subjects provided informed consent, an anonymous interview, and a venous blood sample for serologic testing of HIV, HCV, HBV (Cd. Juá rez only) and syphilis antibody. Log-linear models were used to analyze the association between the state of the recruiter and that of the recruitee in the referral chains, and population estimates of the presence of syphilis antibody were obtained, correcting for biased sampling using RDS-based estimators. Sampling of the targeted 200 recruits per city was achieved rapidly (2 months in Tijuana, 2 weeks in Cd. Juá rez). After excluding seeds and missing data, the sample prevalence of HCV, HIV and syphilis were 96.6, 1.9 and 13.5% respectively in Tijuana, and 95.3, 4.1, and 2.7% respectively in Cd. Juá rez (where HBV prevalence was 84.7%). Syphilis cases were clustered in recruitment trees. RDS-corrected estimates of syphilis antibody prevalence ranged from 12.8 to 26.8% in Tijuana and from 2.9 to 15.6% in Ciudad Juá rez, depending on how recruitment patterns were modeled, and assumptions about how network size affected an individual_s probability of being included in the sample. RDS was an effective method to rapidly recruit IDUs in these cities. Although the frequency of HIV was low, syphilis prevalence was high, particularly in Tijuana. RDS-corrected estimates of syphilis prevalence were sensitive to model assumptions, suggesting that further validation of RDS is necessary.
