Willingness to Receive Latent Tuberculosis Infection Treatment Among Migrants in Tijuana, Baja California, Mexico
Over 80% of tuberculosis cases in the United States are due to reactivation of untreated latent tuberculosis infection (LTBI), most of whom were foreign born. LTBI treatment can greatly lower the risk of progression to active TB disease, and shorter treatment regimens increase the potential of migrants and other persons in vulnerable conditions, to complete treatment. We conducted across-sectional study to assess willingness to complete a one-mon…

Linkage to hepatitis C virus care in a binational cohort study of People who inject drugs on the U.S.-Mexico border
Our study shows poor linkage to HCV-related care among PWID in both San Diego and Tijuana, along with low treatment completion. MOUD programs could be an efficient touchpoint to improve access to HCV care
Water, sanitation, and hygiene access among people who inject drugs in Tijuana and San Diego in 2020–2021
WASH access among PWID in the Tijuana-San Diego metropolitan area was low by international standards and lower than the national averages in both countries. Homelessness was significantly associated with WASH insecurity in this population. Concentrated efforts are needed to guarantee continuously available WASH services for PWID-especially those who are unsheltered
WaSH insecurity and anxiety among people who inject drugs in the Tijuana-San Diego border region
The lack of specific WaSH services, particularly lack of drinking water, toilets, and daily showers were associated with higher levels of anxiety among PWID in the Tijuana-San Diego border region. Women experiencing homelessness were especially vulnerable. WaSH interventions that provide safe, 24-h access may help to reduce anxiety and health risks associated with WaSH insecurity
Safe Injection Self-Efficacy is Associated with HCV and HIV Seropositivity Among People Who Inject Drugs in the San Diego–Tijuana Border Region
Long-acting Injectable PrEP Interest and General PrEP Awareness among People who Inject Drugs in the San Diego-Tijuana Border Metroplex
A mixed methods study to inform fatal overdose prevention in San Diego, California
Water, sanitation and hygiene insecurity predict abscess incidence among people who inject drugs in a binational US–Mexico metropolitan area
PWID in the Tijuana-San Diego metropolitan area reported facing high rates of insecurity accessing WASH services. Abscess incidence was higher (four to nine times) than observed rate among PWID cohorts in other settings. Access to continuously available toilet facilities, bathing infrastructure, and safe water sources for preparing drugs for injection could prevent abscesses among PWID. Accessible WASH infrastructure should be ensured among PWID …
Covid-19 vaccine uptake among people who inject drugs in Tijuana Mexico
Background: SARS-CoV-2 prevalence is elevated among people who inject drugs (PWID). In Tijuana, Mexico, COVID-19 vaccines became available to the general population in June 2021, but uptake among PWID was <10%. We studied COVID-19 vaccine uptake among PWID in Tijuana following implementation of a pop-up vaccination clinic. Methods: Beginning in October, 2020, PWID in Tijuana aged ≥18 years were enrolled into a longitudinal cohort study. At baseli…
A cross-sectional study of factors associated with Covid-19 testing among people who inject drugs
We identified several factors independently associated with COVID-19 testing and multiple touchpoints where COVID-19 testing could be scaled up for PWID, such as SUD treatment programs and syringe service programs. Integrated health services are needed to improve access to rapid, free COVID-19 testing in this vulnerable population

We used intensive participant-observation ethnography among street-based PWUD and key informants, such as frontline physicians and harm reductionists. Results. PWUD described an unprecedented cessation of police violence and extortion during the initial pandemic-related lockdown, though …
Correlates of impulsivity among female sex workers in Mexico
Impulsivity is a trait characteristic that is associated with sexual risk behavior. We examined correlates of impulsivity among 602 female sex workers (FSWs) enrolled in a sexual risk reduction intervention in Mexico (2016-2020). Impulsivity was positively associated with condomless sex with clients. Higher levels of impulsivity were associated with greater use of alcohol and heavy drugs, use of illicit drugs with clients, sexual/physical abuse h…
Perceived barriers to pre-exposure prophylaxis use and the role of syndemic factors among female sex workers in the Mexico-United States border region
Female sex workers (FSWs) experience syndemic factors (e.g., polydrug use, hazardous alcohol consumption, client-perpetrated violence, depression, and sexually transmitted infections) that often heighten vulnerability to HIV and limit healthcare utilization. We hypothesized that syndemic factors will limit FSWs' uptake of pre-exposure prophylaxis (PrEP). From 2016 to 2017, 295 HIV-negative FSWs were enrolled in a behavioral HIV prevention trial i…
Recent HIV Infection among men who have sex with men and transgender women in Tijuana
OBJECTIVE: To characterize recent HIV infections among newly diagnosed men who have sex with men and transgender women in Tijuana. METHODS: Limiting Antigen (LAg)-Avidity testing was performed to detect recent HIV infection within a cohort of newly-diagnosed men who have sex with men and transgender women in Tijuana. Logistic regression was used to determine characteristics associated with recent infection. A partial transmission network was infe…

Vulnerabilities faced by the children of sex workers in two Mexico–US border cities
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…
Predictors of Injection Cessation and Relapse among Female Sex Workers who Inject Drugs in Two Mexican-US Border Cities
Perceived risk of HIV infection among deported male injection drug users in Tijuana, Mexico
Deported injection drug users (IDUs) in Mexico may be vulnerable to HIV infection following expulsion from the USA. We examined factors associated with HIV risk perception among a sample of deportees in Tijuana. From January to April 2010, 313 male IDUs who reported ever being deported from the USA completed a questionnaire. Overall, 35% (N=110) of deportees perceived HIV risk. In multivariate logistic regression analyses, factors independently a…

Predictors of adherence to treatment for latent tuberculosis infection in high-risk Latino adolescents
Polydrug Use among IDUs in Tijuana, Mexico
Tijuana is situated on the Mexico-USA border adjacent to San Diego, CA, on a major drug trafficking route. Increased methamphetamine trafficking in recent years has created a local consumption market. We examined factors associated with methamphetamine use and routes of administration by gender among injection drug users (IDUs). From 2006-2007, IDUs > or =18 years old in Tijuana were recruited using respondent-driven sampling, interviewed, and te…
Barriers to Pharmacy-Based Syringe Purchase Among Injection Drug Users in Tijuana, Mexico
Injection drug users (IDUs) may be denied purchase of sterile syringes even where purchase without a prescription is legal. This study examined barriers to over-the-counter (OTC) syringe purchase among IDUs in Tijuana, Mexico. A quantitative survey and subsequent focus groups were used to quantify barriers to purchase, identify their correlates and provide in-depth exploration of syringe purchase experiences. Of 627 IDUs, 81% purchased a syringe …
Managing la malilla
Our results point to the need for political, economic, and social investment in the drug treatment system before offenders are sentenced to treatment under the revised national drug law. Resources are needed to strengthen program quality and ensure accountability. The public health impact of the new legislation that attempts to bring drug treatment to the forefront of national drug policy should be systematically evaluated
Social and Structural Factors Associated with HIV Infection among Female Sex Workers Who Inject Drugs in the Mexico-US Border Region
BACKGROUND: FSWs who inject drugs (FSW-IDUs) can acquire HIV through high risk sexual and injection behaviors. We studied correlates of HIV infection among FSW-IDUs in northern Mexico, where sex work is quasi-legal and syringes can be legally obtained without a prescription. METHODS: FSW-IDUs>18 years old who reported injecting drugs and recent unprotected sex with clients in Tijuana and Ciudad Juarez underwent surveys and HIV/STI testing. Logist…
Circular Migration by Mexican Female Sex Workers Who are Injection Drug Users
Exploring the Impact of Underage Sex Work Among Female Sex Workers in Two Mexico–US Border Cities
Study protocol for the recruitment of female sex workers and their non-commercial partners into couple-based HIV research
The protocol successfully enrolled 214 high risk couples into a multi-site public health study. This work suggests the importance of collaborating to construct a study protocol, understanding the local population and context, and drawing on multiple sources of input to determine eligibility and verify the legitimacy of relationships. We provide a practical set of tools that other researchers should find helpful in the study of high risk couples i…

Collateral damage from police practices in the context of Mexico's drug conflict may affect public health in the Northern Border Region. Itinerant officers may facilitate disease spread beyond the region. The urgency for mounting structural interventions is discussed
Syringe Confiscation as an HIV Risk Factor
Spatial Epidemiology of HIV Among Injection Drug Users in Tijuana, Mexico
hotspot near the Mexico/U.S. border, encompassing the red-light district. Spatial correlates of HIV included syphilis infection, female gender, younger age, increased hours on the street per day, and higher number of injection partners. Almost all HIV seroconverters injected within a 2.5 block radius of each other immediately prior to seroconversion. Only history of syphilis infection and female gender were strongly associated with HIV in the are…
Deportation Experiences of Women Who Inject Drugs in Tijuana, Mexico
Deportation from the United States for drug offenses is common, yet the consequences of deportation for women drug users are poorly documented. In 2008, in Tijuana, Mexico, we conducted an exploratory qualitative study of migration, deportation, and drug abuse by interviewing 12 Mexican injection-drug-using women reporting U.S. deportation. Women reported heavy drug use before and after deportation, but greater financial instability and physical …
