Illicit drug use and sexually transmitted infections among young adults in the US: evidence from a nationally representative survey

Prevalence, characteristics, and associated risk factors of drug consumption and chemsex use among individuals attending an STI clinic (EpITs STUDY)

Sex-related drug consumption and its health-related consequences have gained relevance in the assessment of patients with sexually transmitted infections (STIs), which pose a significant challenge to public health. We aim to assess the prevalence and characteristics of drug consumption and chemsex practices, describe the associated risk factors among general individuals attending an STI clinic, and evaluate the psychological impact associated with these behaviors. We conducted an online anonymous survey offered to patients with a diagnosis of STI in a tertiary hospital in Spain. Data included sociodemographic characteristics, sexual preferences and behavior, and assessment of drug use, chemsex, and psychological and mental health symptoms. Data from 145 subjects was collected, with a higher proportion of cis-gender men (71%), and a median age of 32 years. 64 participants (44%) reported drug use in the last year, with an observed 33.8% prevalence of chemsex consumption. Drug use and chemsex were more frequent among cis-gender men, Men who have Sex with Men (MSM), people living with HIV (PLHIV), and those reporting previous group sex. Poppers and cannabis were the most frequently reported drugs, with a prevalence close to 20% for cocaine, mephedrone, extasis, and GHB. Consequences related to drug use included unpleasant physical sensations, sexual dysfunction, and impaired sexual experience after reduction or drug discontinuation. The prevalence of drug use and chemsex practices are high among patients evaluated for STIs, especially between men, MSM, and subjects practicing group sex. The study highlights the urgent need for targeted interventions on prevention and reduction of their impact on health and social well-being.

Sexually Transmitted Infections in Women of Reproductive Age by Disability Type

INTRODUCTION

The objectives of this study were to estimate the prevalence of sexually transmitted infections in women of reproductive age by disability type and examine the association between disability types, participant characteristics, and the prevalence of sexually transmitted infections (STIs).

METHODS

Pooled data from 2015 to 2019 National Survey on Drug Use and Health were analyzed in 2022. The analytic sample included 90,233 women of reproductive age (18-49 years). Disability was defined as having any sensory, cognitive, physical, or ≥2 disabilities.. A total of 15% of women reported having a disability. Descriptive analyses were used to estimate the prevalence of STI, and logistic regression analyses were conducted to examine the association of disability type and other participant characteristics with the odds of having STIs.

RESULTS

The prevalence of STIs was more than twice as high for women of reproductive age with cognitive disabilities (6.8%) or ≥2 disabilities (6.7%) as for those without disabilities (2.7%). Women with sensory disabilities (AOR=1.47; 95% CI=1.17, 1.85), cognitive disabilities (AOR=1.89; 95% CI=1.65, 2.17), or ≥2 disabilities (AOR=1.78; 95% CI=1.49, 2.14) had greater odds of STIs than those without disabilities. Bisexual women had higher odds (AOR=1.31; 95% CI=1.14, 1.50) of STIs than straight women, whereas lesbian/gay women had lower odds (AOR=0.41; 95% CI=0.27, 0.63). The odds of STIs were higher among non-Hispanic Blacks (AOR=1.42; 95% CI=1.24, 1.63) and lower among Asian women (AOR=0.62; 95% CI=0.43, 0.90) than among non-Hispanic Whites. The odds of STIs were also greater among participants having any alcohol, cannabis, or illicit drug use.

CONCLUSIONS

Women of reproductive age with disabilities have a higher prevalence of sexually transmitted infections. In addition to disability type, the odds of sexually transmitted infections varied by race/ethnicity, sexual orientation, and substance use.

Changes in Substance Use and Sexual Behaviors After a Sexually Transmitted Infection Diagnosis Among a Cohort of Men Who Have Sex With Men in Los Angeles, CA

Background:

Sexually transmitted infections (STIs), STI reinfection, Human Immunodeficiency Virus (HIV) acquisition and changes in behaviors following an STI were examined in a cohort of men who have sex with men (MSM) in Los Angeles, CA.

Methods:

Data from a longitudinal study of MSM enrolled from 2014 with at least one follow-up visit through March 2020 were analyzed (n=447; 1,854 visits). Study visits every 6 months included self-interviews for sexual behaviors, substance use, and specimen collection for chlamydia, gonorrhea, syphilis, and HIV testing. Changes in behaviors were assessed using McNemar’s test and participants not diagnosed with an STI served as controls for a difference-in-differences (DiD) analysis of changes over time.

Results:

Cumulative incidence of an STI was 55% (248/447). At 24-months post STI diagnosis methamphetamine use declined from 50% to 35% (p<.01), and median number of sex partners declined from 5 (IQR: 2–11) to 2 (IQR: 1–6)(p<.01). Among participants at risk for HIV and diagnosed with an STI (n=102), PrEP use was 35% and HIV-seroconversion was 6%. Based on DiD analyses, participants diagnosed with an STI had higher levels of substance and higher number of sex partners when compared to those with no STIs, however, declines in these behaviors were comparable to participants not diagnosed with an STI (pDID>0.05).

Conclusions:

Despite behavior modifications following an STI diagnosis, STI/HIV incidence was high, suggesting that MSM with STIs occupy sexual networks where reductions in sexual and substance using behaviors do not protect them from ongoing exposure to STIs and HIV.

Despite declines in substance use and sexual behaviors following an STI, reinfections were high suggesting that MSM with STIs occupy sexual networks with high transmission probabilities and prevention efforts should consider sexual network characteristics.

Collateral Damage: A Narrative Review on Epidemics of Substance Use Disorders and Their Relationships to Sexually Transmitted Infections in the United States

ABSTRACT

Associations between substance use disorders and outbreaks of HIV and acute viral hepatitis have received considerable attention, but less research has focused on links between substance use disorders and sexually transmitted infections, apart from alcohol misuse. This narrative review describes the history of this public health crisis in the United States and direct and indirect effects opioids and specific stimulants have on high-risk sexual behaviors. We also review the epidemiology of sexually transmitted infections associated with opioids and stimulants in the United States and discuss opportunities for integrated interventions.
