    Exploration of weekly variation in naloxone possession and carriage among people who use opioids in New York City before, during, and after the COVID-19 pandemic
    (Public Library of Science, 2024-07-18) Roth, Alexis M.; Ward, Kathleen M.; Hensel, Devon J.; Elliott, Luther; Bennett, Alex S.; Pediatrics, School of Medicine
    Background: Naloxone is critical for reversing opioid-related overdoses. However, there is a dearth of research examining how naloxone possession and carriage are impacted by time-varying individual and social determinants, and if this differed during the height of the COVID-related mitigation measures (e.g., shutdowns). Methods: We utilized weekly ecological momentary assessments (EMA) to measure factors associated with naloxone possession and carriage among 40 people who use illicit opioids in New York City, for 24 months. Descriptive statistics were used to explore the frequency of weeks with consistent naloxone possession and carriage. Mixed effects binary and multivariable logistic regression was used to test for the impact of time-varying EMA- and baseline-level factors on each outcome. Results: Approximately 70% of weekly EMAs were associated with consistent naloxone possession or carriage. In multivariable models, compared to during the height of the COVID-related shutdowns (March 12, 2020-May 19, 2021), the time before was associated with lower odds of consistent possession (Odds Ratio (OR) = 0.05, 95% Confidence Interval (CI) = 0.01-0.15) and consistent carriage (OR = 0.06, CI = 0.01-0.25). Additionally, being female (OR = 11.15, CI = 2.85-43.42), being White versus being Black or Hispanic/Latinx (OR = 8.05, CI = 1.96-33.06), and lifetime overdose (OR = 1.96, CI = 1.16-19.80) were associated with higher odds of consistent possession. Recent opioid injection (OR = 3.66, CI = 1.34-9.94), being female (OR = 7.91, CI = 3.91-8.23), and being White (OR = 5.77, CI = 1.35-24.55) were associated with higher odds of consistent carriage. Not wanting to be perceived as a drug user was reported in nearly one third (29.0%; 190/656) of EMAs where inconsistent possession was reported. Conclusions: Our findings paint a relatively positive picture of possession and carriage during COVID-related shutdowns, particularly among white and female participants, and highlight the importance of capturing time-varying factors to understand naloxone-related behavior. To curb growing disparities, outreach to equip Black and Hispanic/Latinx people with naloxone is needed as well as interventions to reduce stigma as a barrier to naloxone engagement.

    ‘I Got it off my Chest’: An Examination of how Research Participation Improved the Mental Health of Women Engaging in Transactional Sex
    (Springer, 2017) Felsher, Marisa; Wiehe, Sarah E.; Gunn, Jayleen K. L.; Roth, Alexis M.; Pediatrics, School of Medicine
    Ecologic momentary assessment (EMA) is a form of close-ended diary writing. While it has been shown that participating in a study that incorporates EMA improves mental health of participants, no study to date has examined the pathways through which benefits may occur. For 4-weeks, twice-daily EMAs and weekly interviews captured mood, daily activities and HIV risk behavior of 25 women who engage in transactional sex. Qualitative analysis of exit interviews was performed to examine how participation impacted women's mental health. The majority of participants felt that EMAs heightened awareness of emotions and behavior. Most reported experiencing catharsis from the interviews; specifically, from having a non-judgmental, trusting listener. Participants felt responsible for completing tasks, a sense of accomplishment for completing the study, and altruism. This study demonstrates there are direct benefits associated with participation in an EMA and interview study.

    Premenarchal Girls' Genital Examination Experiences
    (Elsevier, 2012-08) Robbins, Cynthia L.; Fortenberry, J. Dennis; Roth, Alexis M.; Ott, Mary A.
    Purpose To explore girls' experiences having an external genital examination during early adolescence. Methods Ten premenarchal girls were interviewed about their experiences receiving an external genital examination as part of a larger longitudinal study. Qualitative methods were used for analysis, looking for concepts based on themes and shared beliefs among the girls to create a model of the genital examination experience. Results Most participants could not remember ever having a genital examination before enrollment in the larger study. The examination was best characterized as “weird,” and many aspects of the examination were novel. Overall, genital examinations were not experienced negatively because of moderating factors like having support from mothers during the examination and having examiner preferences toward gender and personal characteristics. With repeated study examinations in the larger study and for those participants who reported their provider performed genital examinations, the examination was viewed as a skill for growing up or routine. Conclusions External genital examinations, although a new experience for many girls, can be experienced positively. Providers should address concerns about this important recommended examination and acknowledge that examiner attributes, mothers, and experience of having examinations all influence how genital examinations are experienced.

    Redefining the Social Geography of Community STI Risk: An Ecological Study of the Association, Mediators, and Moderators of Area-Level Prostitution Arrests
    (2012-03) Wiehe, Sarah E.; Roth, Alexis M.; Burgess, Aaron; Arno, Janet N.; Fortenberry, J. Dennis
    Background: Core groups such as sex workers have been implicated in contributing to higher area STI risk but no studies have analyzed mediators and moderators of this relationship using population data. Objectives: Assess the overall association of area-level prostitution and STI risk, and mediators and moderators of the relationship. Methods: Point-level prostitution and drug arrests were geocoded and aggregated by Census blockgroup. Chlamydia (CT), gonorrhea (GC), syphilis and incident HIV positive test results were aggregated by blockgroup after eliminating same-organism positive tests within 14 days of an initial positive test. Census data also defined moderators: blockgroups with >75% black and >20% Latino (top decile) and >60% below 200% of the federal poverty line (top quartile). Negative binomial and zero-inflated negative binomial regressions were used to estimate incident rate ratios (IRR) of each STI. Results: There was a dose-response relationship between prostitution arrest blockgroup quintiles and IRR of each STI. In models including drug arrest data, this association was completely eliminated. Though % black blockgroup composition had significant interaction with prostitution arrest rates and with respect to its relationship with STI IRR, % Latino did not consistently have this association. Blockgroups with proportions of low minority and low poverty had highest drug arrest IRR for each STI. In these areas, prostitution arrest IRR were only significant for CT and GC and were consistently lower than drug arrest IRRs. Conclusions: Though prostitution arrests are associated with STI risk, this relationship is mediated by drug arrests. Associations of both arrest rates are strongest in low minority, low poverty communities, indicating that high baseline STI prevalence is not moderated by levels of drug and prostitution arrests. Implications for Programs, Policy, and Research: These data suggest that important relationships exist for prostitution and, to a greater degree, drug arrests within communities traditionally defined as ‘low-risk’.

    The Unanticipated Benefits of Behavioral Assessments and Interviews on Anxiety, Self-Esteem and Depression Among Women Engaging in Transactional Sex
    (Springer, 2015-02) Gunn, Jayleen K. L.; Roth, Alexis M.; Center, Katherine E.; Wiehe, Sarah E.; Department of Pediatrics, IU School of Medicine
    Women engaging in transactional sex have disproportional mental health co-morbidity and face substantial barriers to accessing social services. We hypothesized that participation in a longitudinal research study, with no overt intervention, would lead to short-term mental health improvements. For 4-weeks, 24 women disclosed information about their lives via twice daily cell-phone diaries and weekly interviews. We used t tests to compare self-esteem, anxiety, and depression at baseline and exit. Tests were repeated for hypothesized effect modifiers (e.g., substance abuse severity; age of sex work debut). For particularly vulnerable women (e.g., less educated, histories of abuse, younger initiation of sex work) participation in research conferred unanticipated mental health benefits. Positive interactions with researchers, as well as discussing lived experiences, may explain these effects. Additional studies are needed to confirm findings and identify mechanisms of change. This work contributes to the growing body of literature documenting that study participation improves mental health.

    Use of Cell Phone Diaries to Understand Risk Contexts of Sexual Events Among Female Sex Workers
    (2013-07) Roth, Alexis M.; Hensel, Devon J.; Gunn, Jayleen K.L.; Fortenberry, J. Dennis; Garfein, R; Arno, Janet N.; Wiehe, Sarah E.
    Background Data collection using mobile technologies, such as cell phones, allows more frequent and real-time data collection and is less prone to recall bias. We describe the feasibility of using twice daily cell phone diaries to capture contextual features of STI/HIV-risk that could impact disease acquisition among female sex workers (FSW). Methods Women engaging in transactional sex in the prior 90 days were recruited utilising incentivized snowball sampling. Participants completed STI testing and baseline/exit surveys. Over 4-weeks, they completed twice-daily electronic diaries assessing event-level sexual behaviour, condom use, and drug use. Weekly in-person interviews used open-ended questions to explore geographical characteristics of sexual encounter locations as well as acceptability of event-level monitoring. Results 25/26 participants (median age 43.5 years) completed the 4-week study. At baseline, 27% tested positive for a STI. Participants completed 84.5% of 1,518 expected surveys and 95% of 106 expected interviews. Patterns of diary compliance were stable over time. Partnered sexual activity was captured in 21.4% of diaries. At the participant-level, most reported giving oral sex (84.7%) or vaginal sex (96.1%); fewer (19.2%) reported engaging in anal sex. Among women reporting partnered sexual behaviour with any partner type (i.e., new/regular customers, romantic partners), using condoms was reported 39.2%, 45.5% and 83.3% of the time for giving oral sex, vaginal sex, and anal sex respectively. At the event-level, the frequency of giving oral sex, vaginal sex or anal sex did not significantly change over time. Conclusions It is feasible to engage and retain FSW in a technologically-advanced study to characterise risk contexts of sexual events. Adherence to study protocol was high indicating event-level monitoring using cell phone based diaries is acceptable. These data can be utilised to improve our understanding of the individual, relational and environmental factors that influence STI/HIV acquisition among FSW.

    Wearable biosensors have the potential to monitor physiological changes associated with opioid overdose among people who use drugs: A proof-of-concept study in a real-world setting
    (Elsevier, 2021-12-01) Roth, Alexis M.; Tran, Nguyen K.; Cocchiaro, Ben; Mitchell, Allison K.; Schwartz, David G.; Hensel, Devon J.; Ataiants, Janna; Brenner, Jacob; Yahav, Inbal; Lankenau, Stephen E.
    INTRODUCTION: Wearable biosensors have the potential to monitor physiological change associated with opioid overdose among people who use drugs. METHODS: We enrolled 16 individuals who reported ≥ 4 daily opioid use events within the previous 30 day. Each was assigned a wearable biosensor that measured respiratory rate (RR) and actigraphy every 15 s for 5 days and also completed a daily interview assessing drug use. We describe the volume of RR data collected, how it varied by participant characteristics and drug use over time using repeated measures one-way ANOVA, episodes of acute respiratory depression (≤5 breaths/minute), and self-reported overdose experiences. RESULTS: We captured 1626.4 h of RR data, an average of 21.7 daily hours/participant over follow-up. Individuals with longer injection careers and those engaging in polydrug use captured significantly fewer total hours of respiratory data over follow-up compared to those with shorter injections careers (94.7 vs. 119.9 h, p = 0.04) and injecting fentanyl exclusively (98.7 vs. 119.5 h, p = 0.008), respectively. There were 385 drug use events reported over follow-up. There were no episodes of acute respiratory depression which corresponded with participant reports of overdose experiences. DISCUSSION: Our preliminary findings suggest that using a wearable biosensor to monitor physiological changes associated with opioid use was feasible. However, more sensitive biosensors that facilitate triangulation of multiple physiological data points and larger studies of longer duration are needed.
