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
Overlapping Key Populations and HIV Transmission in Tijuana, Mexico
Tijuana, Mexico, has a concentrated HIV epidemic among overlapping key populations (KPs) including people who inject drugs (PWID), female sex workers (FSW), their male clients, and men who have sex with men (MSM). We developed a dynamic HIV transmission model among these KPs to determine the extent to which their unmet prevention and treatment needs is driving HIV transmission. Over 2020-2029 we estimated the proportion of new infections acquired…
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…
Overdose mortality is reducing the gains in life expectancy of antiretroviral-treated people living with HIV in British Columbia, Canada
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…

Factors associated with delayed and late ART initiation among people living with HIV in BC
We examined correlates of late and delayed initiation of antiretroviral therapy (ART) in British Columbia, Canada. From December 2013 to December 2015 we recruited treatment-naïve people living with HIV who initiated ART within the previous year. 'Late initiation' was defined as CD4 cell count ≤500 cells/μL at ART initiation and 'delayed initiation' as ≥1 year between HIV diagnosis and initiation. Multivariable logistic regression assessed indepe…
The Relationship Between Circulating Interleukin-6 Levels and Future Health Service Use in Dementia Caregivers
OBJECTIVE: Older adults are among the most frequent users of emergency departments (EDs). Nonspecific symptoms, such as fatigue and widespread pain, are among the most common symptoms in patients admitted at the ED. Interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) are inflammation biomarkers associated with chronic stress (i.e., dementia caregiving) and nonspecific symptoms. This study aimed to determine whether IL-6 and TNF-α were prospe…

Are men’s misogynistic attitudes associated with poor mental health and substance use behaviors? An exploratory study of men in Tijuana, Mexico
Men's misogynistic attitudes (i.e., dislike or contempt for women) have been shown to be associated with men's perpetration of physical/sexual violence against women and poor health outcomes for women. However, these attitudes have rarely been examined for their influence on men's own health. This paper examines the socio-demographic, substance use, and mental health correlates of misogynistic attitudes among a binational sample of men (n=400) in…
Prevalence and Correlates of Client-Perpetrated Abuse Among Female Sex Workers in Two Mexico–U.S. Border Cities
History of abuse has been associated with greater HIV risk among women. This study examined client-perpetrated abuse among female sex workers (FSWs) in two Mexico-U.S. border cities where HIV prevalence is rising. Among 924 FSWs, prevalence of client-perpetrated abuse was 31%. In multivariate logistic regression models, intimate partner violence (IPV), psychological distress, and having drug-using clients were associated with experiencing client-…
Methamphetamine Use, Attitudes About Condoms, and Sexual Risk Behavior Among HIV-Positive Men Who Have Sex with Men
This study examined attitudes about condoms as a moderator of the relationship between methamphetamine use and sexual risk behavior in a sample of 297 HIV-positive, methamphetamine-using men who have sex with men (MSM). To test for a moderating effect of attitudes towards condoms, an interaction term was included in multiple regression analysis along with age, income, negative condom attitudes, frequency of methamphetamine use, and Beck depressio…
