Substance use and STI acquisition: Secondary analysis from the AWARE study

Area of Science:

• Public Health
• Epidemiology
• Addiction Medicine

Background:

• Sexually transmitted infections (STIs) represent a substantial public health and economic challenge in the U.S.
• Understanding the interplay between substance use and STIs is crucial for effective prevention and treatment strategies.

Purpose of the Study:

• To investigate the association between substance use patterns and the prevalence and incidence of STIs among HIV-negative adults attending STI clinics.
• To explore how these relationships vary across different risk groups defined by gender.

Main Methods:

• Secondary analysis of data from Project AWARE, involving 5012 patients across 9 STI clinics.
• Laboratory assays for STI assessment and self-report for substance use.
• Latent class analysis to identify substance use patterns, with Poisson regression examining their link to STI rates in high-risk populations.

Main Results:

• Distinct patterns of substance use were observed, differing significantly by risk group.
• Substance use was associated with higher STI rates, with variations contingent on specific risk behaviors.
• Participation in substance use treatment correlated with elevated STI rates.

Conclusions:

• Integrating substance use interventions within STI clinics could mitigate associated morbidity.
• Gender-specific sexual health interventions may be beneficial within substance use treatment settings.
