Syndemic Profiles for HIV, Hepatitis C, and Sextually Transmitted Infections Among Mexican American Women Formerly Affiliated with Youth Street Gangs.

We examine syndemic profiles of intimate partner violence, mental health, drug use, incarceration, and infectious diseases (HIV, HCV, and STIs) among a sample of adult Mexican American women who were affiliated with youth street gangs during adolescence through their relationships to boys and men. Latent class analysis included multiple factors along the following dimensions: intimate partner violence, drug use, mental illness, and incarceration. Five unique syndemic profiles were found with varying associations to HIV, HCV, and STI: (1) no syndemic, (2) intimate partner violence, no syndemic, (3) drug use, mental health, and incarceration syndemic, (4) intimate partner violence, drug use (without injection drug use), and mental health syndemic, and (5) intimate partner violence, drug use with injection drug use, mental health, and incarceration syndemic. To successfully prevent HIV, HCV, and STI among gang-involved girls and women, it is necessary to address syndemic factors.
