Difference in Condom Use Between Bear Concordant and Discordant Dyads During the Last Anal Sex Event

Subcultural Identification, Penetration Practices, Masculinity, and Gender Labels within a Nationally Representative Sample of Three Cohorts of American Black, White, and Latina/o LGBQ People

Most quantitative research about lesbian, gay, bisexual, and queer (LGBQ) people's sexual subcultures and sexual practices has used non-probability samples due to data limitations. This paper used the Generations study, a national probability sample of LGBQ Americans in three age cohorts, 18-25 (n = 510), 34-41 (n = 294), and 52-59 (n = 425), who also identified as Black, white, or Latina/o. This paper analyzed men (n = 590) and women (n = 639) to answer the following sets of research questions: (1) What is the prevalence of subcultural identification as bear, leather/kink, twink, and jock among men, and how does it differ by cohort, race/ethnicity, and sexual identity? (2) What is the prevalence of men who describe themselves as a top, versatile top, versatile, versatile bottom, and bottom? What is the relationship between penetration practices and masculinity? (3) What is the prevalence of gender labels among women as femme, androgynous, and butch? How does the prevalence differ by cohort, race/ethnicity, and sexual identity? (4) What is the relationship between women's gender labels and masculinity? Penetration practices were fairly evenly distributed among men, and there were few differences in masculinity based on penetration practices after controlling for demographics and subcultural identification. Most women did not use gender labels, but butch identities were more common among lesbians and femme labels were more common among Black women and Latinas.

Condomless Anal Sex Associated With Heterogeneous Profiles Of HIV Pre-Exposure Prophylaxis Use and Sexual Activities Among Men Who Have Sex With Men: A Latent Class Analysis Using Sex Diary Data on a Mobile App

BACKGROUND

New innovative technologies, such as mobile apps, have been developed to increase pre-exposure prophylaxis (PrEP) adherence and the use of log sex diaries. The contiguity of mobile apps reduces the recall bias that generally affects reported condom and PrEP use. However, none of the currently used mobile apps were designed for event-driven PrEP users, and few studies have demonstrated the potential usage of sex diary data to facilitate the understanding of the different HIV risks among heterogeneous profiles of sex diaries and PrEP use.

OBJECTIVE

We aim to discriminate the heterogeneous profiles of sex events and PrEP use and examine the risk of condomless anal sex among different types of sex events.

METHODS

We recruited 35 adult men who have sex with men from two medical centers in Taiwan since May 2020 and followed up for four months. Participants were on PrEP or willing to take PrEP. They were asked to log their sex events, PrEP use, and dosing regimens on a mobile app to improve their PrEP adherence. Latent class analysis was used to distinguish profiles of sex events and PrEP use. Indicators included correct intake of PrEP for each sex event, participants' sexual positioning, partner's HIV status, and age.

RESULTS

A total of 551 sex events were classified into three classes by latent class analysis: PrEP nonadherent flip-flopping (234/551, 42%), PrEP imperfect-adherent power bottoming (284/551, 52%), and PrEP adherent serodiscordant topping (33/551, 6%). "PrEP nonadherent flip-flopping" sex events were more likely to involve condomless anal sex than "PrEP imperfect-adherent power bottoming" (OR 1.83, 95% CI 1.03-3.25) after considering random intercepts for individuals, and this class needed to increase their PrEP adherence and use of condoms. "PrEP imperfect-adherent power bottoming" realized their own risk and packaged PrEP with condoms to protect themselves. Up to 99% (32/33) of sex events in "PrEP adherent serodiscordant topping" were protected by PrEP, but all of the sex events in this group were condomless.

CONCLUSIONS

Using the sex diary data could advance the capacity to identify high-risk groups. HIV prevention strategy should be more flexible and combine PrEP with condom use for future HIV prevention.

Sexual Subcultures and HIV Prevention Methods: An Assessment of Condom Use, PrEP, and TasP Among Gay, Bisexual, and Other Men Who Have Sex with Men Using a Social and Sexual Networking Smartphone Application

Despite being grouped together in epidemiological risk categories, gay, bisexual, and other men who have sex with men (GBM) are not a homogenous group. In addition to traditional segmentation along race, ethnicity, and socioeconomic status, many GBM also identify with sexual subcultural communities. Previous research has shown differences across a variety of health outcomes between these sexual subcultural communities. The purpose of this study was to determine whether HIV prevention practices among GBM differed according to sexual subcultural community. The study was conducted in collaboration with a popular social and sexual networking smartphone application company. A total of 23,577 GBM responded to the survey. A latent class analysis identified 6 distinct classes related to sexual subcultural community identification. We found significant differences across sociodemographic characteristics, HIV prevention practices, and condomless anal sex in the past 6 months related to sexual subculture identification. Findings suggest that sexual subcultural identity is related to decision-making around HIV prevention among GBM. Differences in HIV prevention strategies are likely a function of group norms, unique shared experiences among GBM identifying with a particular sexual subculture community, and sociodemographic characteristics associated with these groups. As such, sexual subculture identity should be considered in developing interventions and social marketing campaigns to increase uptake of biomedical HIV prevention tools among GBM. Identifying group norms and shared experiences related to HIV prevention practices among sexual subcultures is necessary to understand the role these identities play in lives of GBM, especially as it relates to their sexual health and well-being.

A Concept Analysis of Bear Identity

Members of the bear community, a gay male subculture, offer insight into the development and purveyance of a gay subculture. Using Walker and Avant's concept analysis methodology, concept exploration and a subsequent concept analysis of the term bear identity, using existing literature, was conducted to obtain a better understanding of the meanings of the term bear identity. CINAHL, Psycinfo, Pubmed, Medline, LGBT Life, and ProQuest were employed to identify and examine the data surrounding the concept of bear identity. After conducting the literature review, an analysis of bear identity emerged that explores antecedents, attributes, and possible consequences related to bear identification. Lastly, implications for theory, research, and practice are discussed.

Risk factors associated with sexually transmitted infections among HIV infected men who have sex with men

To investigate the factors associated with sexually transmitted infection and Human Immunodeficiency Virus (STI-HIV) co-infection among men who have sex with men (MSM). A total of 357 HIV-infected participants (84 STI-HIV co-infection and 273 HIV infections only) were recruited from Jiangsu, China. Logistic regression analyses were used to estimate the related factors associated with STI-HIV co-infection. Marginal structural models were adopted to estimate the effect of transmission drug resistance (TDR) on STI-HIV co-infection. For all participants, logistic regression analyses revealed that those who diagnosed with HIV-1 for longer duration (≥1.8 years) were significantly associated with reduced STI-HIV co-infection risk (OR = 0.55, 95%CI: 0.32–0.96, P = 0.036). In further stratification analysis by antiretroviral therapy (ART), individuals with longer duration showed consistent significant associations with STI-HIV co-infection risk (OR = 0.46, 95%CI: 0.26–0.83, P = 0.010) among MSM with ART-naïve status. In addition, significant reduced risk for STI-HIV co-infection (OR = 0.98, 95%CI: 0.96–0.99, P = 0.010) were observed in younger (under the average age of 31.03) MSM of the same group. Interestingly, we also found TDR was significantly associated with an increased risk of STI-HIV co-infection risk (OR = 3.84, 95%CI: 1.05–14.03, P = 0.042) in ART-naïve group. Our study highlights a pattern of STI-HIV co-infection among MSM in China and indicates that targeted interventions aimed at encouraging TDR monitoring in MSM with early HIV infection are warranted.
