“Caballo”: Risk Environments, Drug Sharing And The Emergence Of A Hepatitis C Virus Epidemic Among People Who Inject Drugs In Puerto Rico, Roberto Abadie, K. Dombrowski

Department of Sociology: Faculty Publications

Background: Sharing drug injection equipment has been associated with the transmission of HCV among PWID through blood contained in the cooker and cotton used to prepare and divide up the drug solution. While epidemiologists often subsume this practice under the sharing of “ancillary equipment,” more attention should be paid to the fact that indirect sharing takes place within the process of joint drug acquisition and preparation.

Methods: We employed an ethnographic approach observing active PWID (N = 33) in four rural towns in Puerto Rico in order to document drug sharing arrangements involved in “caballo”, as this practice is locally …

Injection Partners, Hcv, And Hiv Status Among Rural Persons Who Inject Drugs In Puerto Rico, Patrick Habecker, Roberto Abadie, Melissa L. Welch-Lazoritz, Juan Carlos Reyes, Bilal Khan, Kirk Dombrowski

Background—The prevalence of hepatitis C (HCV) and HIV among persons who inject drugs (PWID) and the ability of these diseases to spread through injection networks are well documented in urban areas. However, less is known about injection behaviors in rural areas.

Objectives—This study focuses on the association between the number of self-reported injection partners with the PWID’s self-reported HCV and HIV status. Injection networks provide paths for infection and information to flow, and are important to consider when developing prevention and intervention strategies.

Methods—Respondent driven sampling was used to conduct 315 interviews with PWID in rural Puerto Rico during 2015. …

Rural And Urban Injection Drug Use In Puerto Rico: Network Implications For Human Immunodeficiency Virus And Hepatitis C Virus Infection, Courtney Thrash, Melissa L. Welch-Lazoritz, G. Robin Gauthier, Bilal Khan, Roberto Abadie, Kirk Dombrowski, Sandra Miranda De Leon, Yadira Rolon Colon

Understanding the short- and long-term transmission dynamics of blood-borne illnesses in network contexts represents an important public health priority for people who inject drugs and the general population that surrounds them. The purpose of this article is to compare the risk networks of urban and rural people who inject drugs in Puerto Rico. In the current study, network characteristics are drawn from the sampling “trees” used to recruit participants to the study. We found that injection frequency is the only factor significantly related to clustering behavior among both urban and rural people who inject drugs.

Using Network Sampling And Recruitment Data To Understand Social Structures Related To Community Health In A Population Of People Who Inject Drugs In Rural Puerto Rico, Mayra Coronado-García, Courtney R. Thrash, Melissa L. Welch-Lazoritz, G. Robin Gauthier, Juan Carlos Reyes, Bilal Khan, Kirk Dombrowski

Objective: This research examined the social network and recruitment patterns of a sample of people who inject drugs (PWIDs) in rural Puerto Rico, in an attempt to uncover systematic clustering and between-group social boundaries that potentially influence disease spread.

Methods: Respondent driven sampling was utilized to obtain a sample of PWID in rural Puerto Rico. Through eight initial “seeds”, 317 injection drug users were recruited. Using recruitment patterns of this sample, estimates of homophily and affiliation were calculated using RDSAT.

Results: Analyses showed clustering within the social network of PWID in rural Puerto Rico. In particular, females showed a very …

Hepatitis C Serosorting Among People Who Inject Drugs In Rural Puerto Rico, Ian Duncan, Ric Curtis, Juan Carlos Reyes, Roberto Abadie, Bilal Khan, Kirk Dombrowski

Department of Sociology: Faculty Publications

Due to the high cost of treatment, preventative measures to limit Hepatitis C (HCV) transmission among people who inject drugs (PWID) are encouraged by many public health officials. A key one of these is serosorting, where PWID select risk partners based on concordant HCV status. Research on the general U.S. population bySmith et al. (2013) found that knowledge of one's own HCV status facilitated serosorting behaviors among PWID, such that respondents with knowledge of their own status were more likely to ask potential partners about their status prior to sharing risk. Our objective was to see if this held true …
