Vulnerabilities faced by the children of sex workers in two Mexico–US border cities: a retrospective study on sexual violence, substance use and HIV risk

Most studies of female sex workers (FSWs) conducted in the Mexico–US border region have focused on individual HIV risk, centered on sexual behaviors and substance abuse patterns. Little attention has been drawn to the reality that sex workers are often parents whose children potentially face vulnerabilities unique to their family situation. The objective of the present study was to identify the vulnerabilities faced by the children of FSWs in two Mexican–US border cities. From 2008 to 2010, 628 FSW-injection drug users underwent interviewer-administered surveys and HIV/STI testing. Approximately one in five participants (20%) reported having a parent involved in sex work and majority referred it was their mother (88%). Close to one-third of participants (31%) reported first injecting drugs <18 years of age, and 33% reported they began working regularly as a prostitute <18 years of age. First drinking alcohol <18 years old (AOR = 1.87, 95%CI: 1.13–3.08), lifetime cocaine use (AOR = 1.76, 95%CI: 1.09–2.84), ever being forced or coerced into non-consensual sex as a minor (<18 years of age; AOR = 1.54, 95%CI: 1.01–2.35), and injecting drugs with used syringes in the prior month (AOR = 1.63, 95%CI: 1.07–2.49) were the factors associated with having had a parent involved in sex work. These findings begin to lay the groundwork for understanding the potential vulnerabilities faced by the children of sex workers. Understanding these potential needs is necessary for creating relevant, evidence-based interventions focused on supporting these women.

A binational comparison of HIV provider attitudes towards the use of complementary and alternative medicine among HIV-positive Latino patients receiving care in the US-Mexico border region.

Use of complementary and alternative medicine (CAM) is common among Latinos living with HIV in the United States (US)–Mexico border region. Health providers may vary in their approach to communicating acceptance or non acceptance of CAM use, which can undermine patient confidence in disclosing CAM use. Patient–provider communication about CAM is important because certain types of CAM can affect antiretroviral therapy (ART) adherence. We undertook the present binational study to understand US and Mexican provider beliefs, and perceptions surrounding CAM use among Latino patients, and to learn if and how CAM communication occurs. Between July and December 2010, we conducted in-depth, qualitative interviews in Tijuana and San Diego. Analysis procedures drew upon principles of Grounded Theory. The sample was comprised of 19 HIV-health care providers, including 7 women and 12 men. Emerging CAM-related themes were: Providers perceptions, attitudes and knowledge about CAM; CAM types and modalities; and patient–provider CAM communication. Many clinicians were uncomfortable supporting CAM use with their patients. San Diego providers reported more frequent instances of CAM use among Latino patients than Tijuana providers. Providers from both cities reported that patients infrequently disclose CAM use and almost half do not routinely ask patients about CAM practices. Most of the providers acknowledged that they lack information about CAM, and are concerned about the drug interaction as well as the effects of CAM on adherence. Our findings have important implications for understanding provider communication surrounding CAM use in a highly transnational population and context. Because CAM use may undermine ART adherence and is highly prevalent among Latinos, provider communication about CAM is critical to improved health outcomes among HIV-positive Latinos. Considering the significant growth of US Latinos, especially in the US–Mexico border region, assessment of Mexican and US provider training and communication needs surrounding Latino patient CAM use is warranted.

Choosing sides: HIV health care practices among shared populations of HIV-positive Latinos living near the US-Mexico border.

Background: We compared HIV-positive patients receiving care in the border cities of San Diego, United States, with Tijuana, Mexico. Methods: Participants were HIV-positive Latinos (n = 233) receiving antiretroviral therapy (ART) from San Diego–Tijuana clinics (2009-2010). Logistic regression identified correlates of receiving HIV care in San Diego versus Tijuana. Results: Those with their most recent HIV visit in San Diego (59%) were more likely to be older, have at least a high school education, and were less likely to have been deported than those with last visits in Tijuana. Despite reporting better patient–provider relationships and less HIV-related stigma than those with visits in Tijuana, San Diego patients were twice as likely to make unsupervised changes in their ART regimen. Conclusions: We observed poorer relative adherence among HIV-positive Latinos receiving care in San Diego, despite reports of good clinical relationships. Further study is needed to ascertain underlying reasons to avoid ART-related resistance.

Healthcare provider perspectives on barriers to HIV-care access and utilisation among Latinos living with HIV in the US-Mexico border

Latinos living with HIV residing in the US-Mexico border region frequently seek care on both sides of the border. Given this fact, a border health perspective to understanding barriers to care is imperative to improve patient health outcomes. This qualitative study describes and compares experiences and perceptions of Mexican and US HIV care providers regarding barriers to HIV care access for Latino patients living in the US-Mexico border region. In 2010, we conducted in-depth qualitative interviews with HIV care providers in Tijuana (n = 10) and San Diego (n = 9). We identified important similarities and differences between Mexican and US healthcare provider perspectives on HIV care access and barriers to service utilisation. Similarities included the fact that HIV-positive Latino patients struggle with access to ART medication, mental health illness, substance abuse and HIV-related stigma. Differences included Mexican provider perceptions of medication shortages and US providers feeling that insurance gaps influenced medication access. Differences and similarities have important implications for cross-border efforts to coordinate health services for patients who seek care in both countries.

Tuberculosis Treatment Monitoring by Video Directly Observed Therapy in 5 Health Districts, California, USA

We assessed video directly observed therapy (VDOT) for monitoring tuberculosis treatment in 5 health districts in California, USA, to compare adherence between 174 patients using VDOT and 159 patients using in-person directly observed therapy (DOT). Multivariable linear regression analyses identified participant-reported sociodemographics, risk behaviors, and treatment experience associated with adherence. Median participant age was 44 (range 18–87) years; 61% of participants were male. Median fraction of expected doses observed (FEDO) among VDOT participants was higher (93.0% [interquartile range (IQR) 83.4%–97.1%]) than among patients receiving DOT (66.4% [IQR 55.1%–89.3%]). Most participants (96%) would recommend VDOT to others; 90% preferred VDOT over DOT. Lower FEDO was independently associated with US or Mexico birth, shorter VDOT duration, finding VDOT difficult, frequently taking medications while away from home, and having video-recording problems (p<0.05). VDOT cost 32% (range 6%–46%) less than DOT. VDOT was feasible, acceptable, and achieved high adherence at lower cost than DOT.
