HT-RADAR Revived
More than 30 stakeholders from various San Diego and Tijuana (SD/TJ) educational institutions, government offices, and agencies attended HT-RADAR’s first 2016 meeting on April 29. This meeting will be the first of several quarterly meetings, designed to further strengthen collaboration between human trafficking data analysts and researchers working in the SD/TJ region. Agenda topics included: an overview of the Advisory Council and HT-RADAR, the first annual research conference, collaborative approaches to research funding opportunities, and an HT-RADAR membership structure. As HT-RADAR’s first featured speaker, Dr. Monica Ulibarri presented on the findings of two recent studies that looked at the commercial sexual exploitation of adolescent girls in San Diego County. Research that examines the different aspects of human trafficking in the specific contexts of San Diego and Tijuana can have a more direct and immediate impact on local programs, services, and policies through networks such as HT-RADAR.

ABSTRACT
The current wave of interest in human trafficking and the commercial sexual exploitation of children has exposed a lack of knowledge about the vulnerabilities leading to underage entry into sex work. This knowledge is necessary for the development of effective prevention programs to identify girls who are most at-risk, especially in Latin America, a region that is believed to be a large source of persons moved across international borders for the purposes of sexual and labor exploitation. The objective of this study was to explore and increase understanding of the vulnerability factors and pathways leading to underage entry into sex work experienced by women currently engaging in sex work in two cities on the northern border of Mexico. From August 2013 to October 2014, 20 female sex workers (FSWs) with a history of entry into sex work prior to age 18 were recruited for in-depth interviews from a larger time-location sample of female sex workers (FSWs) participating in a quantitative survey in Tijuana and Ciudad Juarez. The median age of entry into sex work was 14 (range 10-17); 12/21 participants reported being forced into sex work and, of these, 7 were transported to another city where they began engaging in sex work. Family dysfunction (e.g., domestic violence between parents, parent drug use, neglect, etc.), sexual and physical abuse, and teen pregnancy were among the key themes that emerged as vulnerabilities to underage entry into sex work. Women’s narratives clearly illustrated that the vulnerabilities and pathways leading to underage entry are manifold, complex, and often intersect with each other. Our findings begin to lay the groundwork for understanding the potential vulnerabilities and pathways leading to underage entry into sex, and may have relevance to Latin America in general. This study also provides a foundation for further research to explore what may mitigate these vulnerabilities as well as creating evidence-based interventions to prevent commercial sexual exploitation of minors in the region.
Argentina E. Servin, MD, MPH is a Project Scientist at the Division of Global Public Health in the School of Medicine at UCSD. She is a bilingual clinician-researcher who has focused her research on sex-trafficking, HIV prevention, and reproductive health needs among vulnerable underserved women and girls in the US – Mexico border region. Dr. Servin also holds a shared appointment at the Centro de Estudios Universitarios Xochicalco, in the School of Medicine in Tijuana, where she conducts similar research that she combines with her clinical work in urban community health centers across Tijuana.
STUDY SUMMARY
Sexual Violence & HIV Infection Associated with Adolescent vs. Adult Entry into the Sex Trade
Jay G. Silverman, PhD; Argentina E. Servin, MD, MPH; Shira M. Goldenberg, PhD; Carlos Magis-Rodriguez, MD; Julie Ritter, MPH; Anita Raj, PhD; Kimberly C. Brouwer, PhD
- were more likely to experience violence to force commercial sex,
- have higher client volumes,
- were less likely to use condoms during the first 30 days upon entering the sex industry,
- and were more likely to be infected with HIV.
Findings also show that more than one in four FSWs entered the sex industry before age of 18. These research findings highlight the need for more effective interventions that protect adolescents from entering the sex industry and that aid those who are currently in the sex trade.
Jay Silverman, PhD, is Director of Research for the Center on Gender Equity and Health and a Professor of Medicine and Global Public Health at UCSD. He is a leading global researcher on understanding and preventing gender-based violence against adolescent and adult women (e.g., intimate partner violence, sexual violence and sex trafficking).

STUDY SUMMARY
Assessment of Risk Factors for Commercial Sexual Exploitation of High Risk Adolescent Girls in San Diego County
Monica Ulibarri, PhD & Emilio Ulloa, PhD
Co-Investigators: Shira Goldenberg, PhD & Jay Silverman, PhD
Through anonymous semi-structured interviews, Ulibarri, Ulloa, Goldenberg, and Silverman, examined the perspectives of ten adolescent girls with a history of involvement in commercial sexual exploitation of children (CSEC) in San Diego County. All research participants were recruited through targeted and snowball sampling. Half of the interviewees were between 15 and 17 years old and the other half were between the ages of 18 and 20. This study was conducted from April 2013 to March 2014 and was funded by the UCSD Health Sciences, Clinical and Translational Research Institute, Academic-Community Partnership Pilot Grant.
Important Findings
- Running away from home, poverty, and a lack of emotional support are all risk factors for the commercial sexual exploitation of adolescent girls in San Diego County.
- Study participants made suggestions for the prevention of CSEC, which include:
- providing appropriate shelter for runaway girls and
- raising awareness about early warning signs through school programs.
- Social media is utilized for recruitment and advertising of girls.
- Other findings regarding prevention, social media, gang involvement, law enforcement, and mental health were drawn through this research.

STUDY SUMMARY
Measuring the Nature & Extent of Gang Involvement in Sex Trafficking in San Diego

Ami Carpenter, PhD & Jamie Gates, PhD
Carpenter and Gates conducted a three-year study, exploring the nexus between gangs and sex trafficking in San Diego County. Mixed-methods were utilized to collect and synthesize data (qualitative and quantitative) from five major sources: (1) a Survivor Services Dataset from a prostitution first offender diversion program, (2) a Survivor Services Dataset from surveys conducted by eight service providers, (3) Law Enforcement Incident Reporting (combined Police arrest records and Sheriff booking datasets), (4) School Focus Groups, and (5) In-depth interviews with individuals involved in – or knowledgeable about – sex trafficking. In total, data was collected from 1,205 individuals for this study.
Important Findings
- The underground sex economy represents an estimated $810 million in annual revenue.
- The scope of commercial sexual exploitation of people (CSEP) in the County is estimated to range from 3,417 – 8,108 per year.
- 16 years old is the average age of entry into child commercial sexual exploitation (CSEC).
- Sex trafficking facilitators, victims, and survivors are from all parts of the County and are not exclusive to any group.
- Other findings regarding the County’s commercial sex economy, the scope and nature of gang involvement in sex trafficking, and the scope and nature of sex trafficking victimization were observed through this study.
