Methamphetamine initiation among HIV-positive gay and bisexual men

This study describes factors associated with methamphetamine initiation in a racially diverse sample of 340 methamphetamine-using, HIV-positive gay and bisexual men. A factor analysis was conducted on reasons for initiation, and four factors were identified: to party, to cope, for energy, and to improve self-esteem. Methamphetamine to party accounted for more than one-third of the variance in the factor analysis. Methamphetamine to cope captured almost 9% of the variance, methamphetamine for energy accounted for approximately 8% of the variance, and methamphetamine for self-esteem accounted for approximately 7% of the variance. Regression analyses revealed differential associations between methamphetamine-initiation factors and HIV-risk behaviors. Methamphetamine for self-esteem predicted binge methamphetamine use, while methamphetamine to cope was associated with injecting methamphetamine. Using methamphetamine for energy was associated with number of illicit drugs-used and using methamphetamine to party was associated with having a greater number of sexually transmitted infections. These findings suggest that methamphetamine initiation among gay and bisexual men is multifaceted, which could have implications for intervention development.
