Behavioral interventions for the primary prevention of HIV infection among homosexual and bisexual men

Sexually transmitted infections and dating app use

Incidence of sexually transmitted infections (STIs) is rising sharply in the United States. Between 2014 and 2019, incidence among men and women has increased by 62.8% and 21.4%, respectively, with an estimated 68 million Americans contracting an STI in 2018.a Some human behaviors impacting the expanding STI epidemic are unprotected sex and multiple sexual partners.b Increasing dating app usage has been postulated as a driver for increases in the numbers of people engaging in these behaviors. Using the proposed model, it is estimated that both STI incidence and prevalence for females and males have increased annually by 9%-15% between 2015 and 2019 due to dating apps usage, and that STI incidence and prevalence will continue to increase in the future. The model is also used to assess the possible benefit of in-app prevention campaigns.ahttps://www.cdc.gov/nchhstp/newsroom/fact-sheets/std/STI-Incidence-Prevalence-Cost-Factsheet.htmbA. N. Sawyer, E.

Psychosocial, behavioral, and cultural predictors of sexual risk for HIV infection among Latino men who have sex with men

This study sought to replicate and extend an investigation by Diaz et al. (1999) on determinants of HIV risk among Latino gay and bisexual men living in San Francisco who were predominantly English-speaking. Compared to the Diaz et al. study, the current study sample consisted of predominantly Spanish-speaking MSM, who resided outside of HIV/AIDS epicenters and whose countries of origin were primarily Central & South American. The relationships of unprotected anal sex and multiple sexual partners with demographic, developmental, behavioral, cultural and psychosocial variables were examined. Data were collected in a convenience sample of 250 participants (primarily immigrants from El Salvador) residing in Virginia. Most men in the sample had more than one sexual partner in the last 3 months (62%) and more than a third had unprotected anal sex with a casual partner in the same time period. Communication about HIV, sexual attraction, machismo, and experiences of discrimination based on homosexual behavior were predictive of HIV risk behaviors. The findings support an integrative approach to investigating HIV risk among Latino MSM. Implications for prevention programs are discussed.
