Event-level patterns of methamphetamine and poly-drug use among millennial sexual minority men: The P18 Cohort Study.

ABSTRACT:

Introduction

Knowledge on methamphetamine use among a new generation of sexual minority men (SMM) is limited. This study describes the event-level patterns of methamphetamine use and characteristics of methamphetamine users across time among Millennial SMM emerging into adulthood.

Methods

A prospective cohort study was conducted in two waves: 2009-2014 (Wave I) and 2014-2019 (Wave II) in the New York City metropolitan area. A total of 600 Millennial SMM ages 18-19 years were recruited for Wave I. A total of 665 SMM ages 22-23 years were recruited for Wave II, of which 41.2% (n = 274) were retained from Wave I. The Timeline Followback assessment was conducted every six months to record event-level drug use in the 30 days prior to the visit.

Results

A total of 5.4% of participants of between the ages of 18-27 reported methamphetamine use throughout the study period. The average number of days of methamphetamine use was significantly higher among racial/ethnic minority men in Wave II (F = 4.34, p = 0.0029). We found methamphetamine use occurred more often on weekend days and same-day use of methamphetamine occurred most often with cannabis and gamma-hydroxybutyrate. Usage of methamphetamine was significantly greater among SMM in Wave II who by design were older than Wave I.

Conclusion

We have identified differences in methamphetamine use by race/ethnicity. Weekend use and poly-drug use were common among methamphetamine-using SMM. Data indicate differential use in the population and that attempts to address this addictive behavior must be linked to other drug use and socialization among young SMM.

Project description:BackgroundSexual minority men are disproportionately affected by methamphetamine use, with recent studies suggesting an increase in use specifically among Black sexual minority men. Black sexual minority men face unique structural barriers to achieving optimal health. Given its harmful effects, and in light of existing health disparities, an increase in methamphetamine use among Black sexual minority men poses a significant public health concern.ObjectiveThe Health Impacts and Struggles to Overcome the Racial Discrimination of Yesterday (HISTORY) study is investigating the potential impacts of exposure to the census tract-level structural racism and discrimination (SRD) on methamphetamine use among Black sexual minority men in Atlanta, Georgia, and will identify intervention targets to improve prevention and treatment of methamphetamine use in this population.MethodsThis study uses a mixed methods and multilevel design over a 5-year period and incorporates participatory approaches. Individual-level quantitative data will be collected from a community-based cohort of Black sexual minority men (N=300) via periodic assessment surveys, ecological momentary assessments, and medical record abstractions. Census tract-level measures of SRD will be constructed using publicly available administrative data. Qualitative data collection will include longitudinal, repeated in-depth interviews with a subset (n=40) of study participants. Finally, using a participatory group model-building process, we will build on our qualitative and quantitative data to generate causal maps of SRD and methamphetamine use among Black sexual minority men, which in turn will be translated into actionable recommendations for structural intervention.ResultsEnrollment in the HISTORY study commenced in March 2023 and is anticipated to be completed by November 2024.ConclusionsThe HISTORY study will serve as a crucial background upon which future structural interventions can be built, to mitigate the effects of methamphetamine use and SRD among Black sexual minority men.International registered report identifier (irrid)DERR1-10.2196/63761.

Project description:IntroductionIn the era of HIV treatment as prevention (TasP), evidence-based interventions that optimize viral suppression among people who use stimulants such as methamphetamine are needed to improve health outcomes and reduce onward transmission risk. We tested the efficacy of positive affect intervention delivered during community-based contingency management (CM) for reducing viral load in sexual minority men living with HIV who use methamphetamine.MethodsConducted in San Francisco, this Phase II randomized controlled trial tested the efficacy of a positive affect intervention for boosting and extending the effectiveness of community-based CM for stimulant abstinence to achieve more durable reductions in HIV viral load. From 2013 to 2017, 110 sexual minority men living with HIV who had biologically confirmed, recent methamphetamine use were randomized to receive a positive affect intervention (n = 55) or attention-control condition (n = 55). All individual positive affect intervention and attention-control sessions were delivered during three months of community-based CM where participants received financial incentives for stimulant abstinence. The 5-session positive affect intervention was designed to provide skills for managing stimulant withdrawal symptoms as well as sensitize individuals to natural sources of reward. The attention-control condition consisted of neutral writing exercises and self-report measures.ResultsMen randomized to the positive affect intervention displayed significantly lower log10 HIV viral load at six, twelve and fifteen months compared to those in the attention-control condition. Men in the positive affect intervention also had significantly lower risk of at least one unsuppressed HIV RNA (≥200 copies/mL) over the 15-month follow-up. There were concurrent, statistically significant intervention-related increases in positive affect as well as decreases in the self-reported frequency of stimulant use at six and twelve months.ConclusionsDelivering a positive affect intervention during community-based CM with sexual minority men who use methamphetamine achieved durable and clinically meaningful reductions in HIV viral load that were paralleled by increases in positive affect and decreases in stimulant use. Further clinical research is needed to determine the effectiveness of integrative, behavioural interventions for optimizing the clinical and public health benefits of TasP in sexual minority men who use stimulants such as methamphetamine.
