Injection and Heterosexual Risk Behaviors for HIV Infection Among Non-gay Identifying Men Who Have Sex with Men and Women

Racial Differences of Psychosocial Characteristics, HIV Risk-Taking and HIV Prevention Uptake between Men Who Have Sex with Men Only and Men Who Have Sex with Men and Women: A Community-Based Study in Two US Cities

Bisexual behavior preference plays an important role in shaping HIV risks among men who have sex with men (MSM), yet few studies have examined the racial differences in the patterns of sexual risk and HIV prevention uptake between men who have sex with men and women (MSMW) and men who have sex with men only (MSMO). We conducted a community-based study to identify and compare psychosocial characteristics, sexual risks, HIV testing frequency, and pre-exposure prophylaxis (PrEP) engagement between Black and White MSMW and MSMO in two US cities. Findings indicate that White MSMW were most likely to engage in HIV risk-taking behaviors (e.g., alcohol/drug use before sex, condomless/group sex), while Black MSMW were least likely to recently test for HIV or report awareness (aPR: 0.32, 95% CI: 0.17-0.61), willingness (aPR: 0.58, 95% CI: 0.30-0.98), and use (aPR: 0.59, 95% CI: 0.31-0.93) of PrEP. Findings from our study supplement salient information for designing culturally tailored HIV prevention interventions for specific MSM subgroups in the US.

Personal and Lifestyle Determinants of HIV Transmission Risk in Spanish University Students

The increase in human immunodeficiency virus (HIV) transmission cases poses a serious public health concern. Although several previous studies have been conducted with the aim of identifying the risk factors for HIV transmission, the number of cases has been increasing, especially in youth. The present study is aimed at the identification of personal and lifestyle determinants of HIV transmission risk in a sample of 335 Spanish university students selected by convenience sampling from a public university located in Alicante (Spain). Sociodemographic factors, lifestyles, and variables of HIV risk of transmission were evaluated. Group differences on risk of HIV transmission were evaluated between participants depending on their sociodemographic characteristics (age, sex, relationship status, employment status, economic status, and sexual orientation) and lifestyle (diet, physical exercise, smoking, alcohol consumption, and stress). Linear regression models were conducted in order to identify those personal and lifestyle variables related to HIV transmission risk. The obtained results indicate that, generally, being older, in a relationship, and employed were factors related to a high risk of HIV transmission. Regarding lifestyle, poor diet, lower intensity of physical exercise, higher alcohol intake, and smoking were fundamentally associated with a higher risk of HIV transmission, through lower use of condoms and higher frequency of risky sexual behaviors. Hence, participants who develop an unhealthy lifestyle exhibit twice the probability of being at a high risk of HIV transmission, especially regarding these previously indicated behaviors. The present study points out the relevance of sociodemographic characteristics and lifestyles of university students in their proneness to developing risky behaviors for HIV infection. Future studies should be developed with larger, randomized, and more representative samples, in order to obtain significant information for the development of effective preventive strategies oriented toward the increase in the adherence to healthy lifestyles and HIV prevention.
