Lesbian, gay, and bisexual (LGB) adolescents report disparate rates of substance use, and often consume more cigarettes, alcohol, marijuana, cocaine, and ecstasy than their heterosexual peers. It is therefore crucial to understand the risk factors for substance use among LGB adolescents, particularly those unique to their minority status. In an effort to organize the current knowledge of minority-related risk factors for substance use among LGB youth, this study presents results from a systematic review and meta-analysis of the published research literature. Results from 12 unique studies of LGB youth indicated that the strongest risk factors for substance use were victimization, lack of supportive environments, psychological stress, internalizing/externalizing problem behavior, negative disclosure reactions, and housing status. Results are discussed in terms of their implications for targeted intervention programs that address minority stress risk factors for substance use among LGB youth.

Young men who have sex with men (YMSM) are increasingly using mobile smartphone applications (“apps”), such as Grindr, to meet sex partners. A probability sample of 195 Grindrusing YMSM in Southern California were administered an anonymous online survey to assess patterns of and motivations for Grindr use in order to inform development and tailoring of smartphone-based HIV prevention for YMSM. The number one reason for using Grindr (29%) was to meet “hook ups.” Among those participants who used both Grindr and online dating sites, a statistically significantly greater percentage used online dating sites for “hook ups” (42%) compared to Grindr (30%). Seventy percent of YMSM expressed a willingness to participate in a smartphone app-based HIV prevention program. Development and testing of smartphone apps for HIV prevention delivery has the potential to engage YMSM in HIV prevention programming, which can be tailored based on use patterns and motivations for use.

Objectives: Smartphone geosocial networking applications, like Grindr, have become a new context through which young men who have sex with men (YMSM) can meet potential sex partners. Geosocial networking applications move beyond online social networking websites like Facebook by utilizing smartphones' geo-location functions to facilitate connections with other users based on their current physical location. This study presents data on HIV risk-taking behaviors of YMSM who use Grindr, comparing the sex behaviors with partners met via the application to behaviors with partners met via other means (e.g., a bar, through friends, online). Methods:Utilizing the geo-locating feature of Grindr, 195 YMSM, aged 18 to 24, were randomly recruited based on their location within West Hollywood and Long Beach, CA between August and October, 2011. Participants completed an online survey.Results: YMSM reported using Grindr for entertainment, socializing, partner seeking, and gay community connection. Seventy-five percent of users reported sexual encounters with partners met on Grindr. YMSM reported significantly higher rates of condom use with partners met on Grindr (59.8%) relative to those partners met elsewhere (41.9%). Only 14.7% reported unprotected anal intercourse (UAI) with their last Grindr partner. YMSM who reported UAI with their last partners from Grindr reported significantly more recent male anal sex partners than YMSM who reported no UAI with their last Grindr-met partners. Conclusions:Grindr was used by YMSM for a variety of reasons, and not exclusively for the purpose of sex partner seeking. Overall YMSM who use Grindr practice safer sex with partners met via the application than with partners met elsewhere. YMSM engaging in UAI with partners on Grindr are an especially high-risk group and should be targeted by prevention efforts. Sexual risk behavior with geosocial networking-located partners could be addressed with mobile HIV prevention applications, or within Grindr and other similar applications.

Online social networking refers to the use of internet-based technologies that facilitate connection and communication between users. These platforms may be accessed via computer or mobile device (e.g., tablet, smartphone); communication between users may include linking of profiles, posting of text, photo and video content, instant messaging and email. This review provides an overview of recent research on the relationship between online social networking and sexual risk and protective behaviors with a focus on use of social networking sites (SNS) among young people and populations at high risk for sexually transmitted infections (STIs). While findings are mixed, the widespread use of SNS for sexual communication and partner seeking presents opportunities for the delivery and evaluation of public health interventions. Results of SNS-based interventions to reduce sexual risk are synthesized in order to offer hands-on advice for clinicians and researchers interested in engaging patients and study participants via online social networking.

Previous research indicates that lesbian, gay, and bisexual (LGB) adolescents are at increased risk for substance use, including heightened rates of marijuana use. Minority stress theory suggests that difficult social situations create a state of chronic stress that leads to poor health outcomes for LGB adults; however, the applicability of this model has not been well explored in relation to substance use among LGB adolescents. The current study is a secondary analysis of the OutProud survey, conducted in 2000. The original study used purposive sampling to collect data from 1,911 LGB adolescents (age 12-17) across the United States, and represents the largest known study to explore experiences specific to identifying as LGB, such as homophobia and gay-related victimization. We used structural equation modeling (SEM) to explore the feasibility of applying a minority stress framework to understand marijuana use in this population. The final structural model for marijuana use in the LGB adolescent sample displayed excellent fit and modest explanatory power for marijuana use. Two of the five factors, community connectedness and internalized homophobia, were significantly (p < .05) associated with marijuana use. Findings suggest that minority stress theory may be appropriately applied to marijuana use in this population; however, better measurement of minority stress concepts for LGB adolescents is needed.
