Differences in Risky Sexual Behavior According to Sexual Orientation in Korean Adolescents

Sexual Behaviors Among Lesbian, Gay, Bisexual, Transgender, and Other Sexual and Gender Diverse Medical Students: A National Study of Thai Medical Schools

Objective

This study aims to investigate sexual behaviors among gender diverse (LGBT and other sexual/gender minorities) and nongender-diverse medical students.

Methods

In 2021 academic year, medical students from five Thai medical schools completed questionnaires identifying demographic data, psychosexual factors, sexual experiences, and risks.

Results

Among 1,322 students, 32.1% were gender-diverse students who had lower age at first sexual intercourse and more experiences in solitary and partnered sexual activity.

Conclusions

Use of hookup applications was more frequent among gay and bisexual males. Risky sexual behaviors were significantly higher among bisexual females. Gender-diverse medical students showed higher involvement in sexual activities. Future studies should be addressing sexual health in Thai medical education.

Comparison of Different Sexual Behaviors According to Sexual Orientation and the Mediating Role of Attitudes toward Sexual Behaviors between Sexual Orientation and Sexual Behaviors in Young Adults

Objectives

To explore the relationship between sexual orientation and specific sexual and risk behaviors, compare the number of sexual behaviors and attitudes among people of different sexual orientations, and test the mediating effect of attitudes toward sexual behaviors in the relationship between sexual orientation and the number of sexual behaviors.

Methods

A total of 2288 participants completed a checklist of sexual behaviors, indicators of sexual risk behaviors, and a scale of attitudes toward sexual behaviors.

Results

Bisexual women engaged in a greater number of sexual behaviors and had more positive attitudes toward sexual behaviors than heterosexual women. Homosexual men engaged in a greater number of sexual behaviors than heterosexual men, and homosexual and bisexual men had more positive attitudes toward sexual behaviors than heterosexuals. Finally, we show the mediating role of attitudes toward sexual behaviors in the relationship between sexual orientation and the number of sexual behaviors engaged in.

Conclusions

The importance of considering sexual orientation when analyzing sexual behaviors and attitudes is highlighted.

Roles of Social Capital in the Association Between Internalized Homophobia and Condomless Sex Among Men Who Have Sex With Men in Southwest China: A Four-Way Decomposition

Objectives: This study examined whether social capital (SC) mediated the association between internalized homophobia (IH) and condomless sex among men who have sex with men (MSM), with the interaction of SC and IH considered. Methods: A cross-sectional study was conducted between November 2018 and April 2019 in Sichuan Province, China. A total of 540 participants were recruited to investigate their IH, SC, and condomless sex. A four-way decomposition of causal mediation analysis was used to test SC's roles in the association between IH and condomless sex. Results: Condomless sex was prevalent (46.7%) among the participants, which was significantly associated with IH [odds ratio (OR) = 1.70] and SC (OR = 0.55). A direct effect [excess risk ratio (RR = 0.32)] and an indirect effect (excess RR = 0.16) of SC were found to be significant in the association between IH and condomless sex. Heterogeneities in effects were observed when taking the SC's domains (e.g., individual and family-based SC) as mediators. SC's effects were significant only in the homosexual subgroup. Conclusion: IH-based intervention with consideration of SC can be tailored to MSM to decrease condomless sex and curb the spread of HIV, especially for the homosexual subgroup.

Gender Differences in the Association Between Sexual Orientation and Risky Sexual Behavior Among College Students With Sexual Experience in Sichuan Province, Chinese

BACKGROUND

Limited information is available regarding risky sexual behavior among college students with different sexual orientations.

AIM

The aim of this study was to examine the gender differences in the association between sexual orientation and risky sexual behavior among Chinese college students with sexual experience.

METHODS

With a self-assessment questionnaire, we conducted a cross-sectional survey among 73,800 students from 25 vocational colleges (3-year colleges) in the Sichuan province of China. Multivariate logistic regression models were used to examine the association between sexual orientation and risky sexual behavior among students with sexual experience.

OUTCOMES

The main outcome measures used regarding risky sexual behavior are the following: condom use in the last sexual intercourse, early sexual debut, and having multiple sexual partners.

RESULTS

12,711 students with sexual experience were included. Sexual minority students were more likely to have an early sexual debut (For male students, homosexual: OR = 1.88, P < .001; bisexual: OR = 1.96, P < .001; unsure: OR = 1.68, P < .001. For female students, homosexual: OR = 1.87, P < .01; bisexual: OR = 2.07, P < .01; unsure: OR = 1.53, P < .05), and less likely to use condoms in their last sexual intercourse (except for homosexual male students) (For male students, bisexual: OR = 0.65, P < .01; unsure: OR = 0.60, P < .001. For female students, homosexual: OR = 0.21, P < .001; bisexual: OR = 0.54, P < .001; unsure: OR = 0.68, tP < .05). There are gender differences in the association between sexual orientation and having multiple sexual partners. Male sexual minorities were more likely to have multiple sexual partners than heterosexual students (homosexual: OR = 2.06, P < .001; bisexual: OR = 1.66, P < .001; unsure: OR = 1.31, P < .05), while the same result was only observed in bisexual female students (OR = 1.46, P < .01).

CLINICAL IMPLICATIONS

Sexual health education professionals should consider the sexual orientation of students when providing counseling services or educational intervention, especially for male students and LGBT ones.

STRENGTHS & LIMITATIONS

We examined gender differences in the association between sexual orientation and risky sexual behavior among college students with sexual experience. However, the ability for the cross-sectional survey to address causality is limited, and will be further tested in cohort studies.

CONCLUSION

Gender and sexual orientation affect the likelihood of risky sexual behavior among China's college students, and gender differences in the association between sexual orientation and risky sexual behavior should be noticed.

Disparities in alcohol use and heavy episodic drinking among bisexual people: A systematic review, meta-analysis, and meta-regression

BACKGROUND

Alcohol consumption is more prevalent among sexual minorities than among heterosexuals; however, differences between minority sexual orientation groups are understudied. This systematic review and meta-analysis aimed to summarize existing evidence on the prevalence of alcohol use among bisexual people compared to their lesbian/gay and heterosexual counterparts.

METHODS

A systematic review of literature from 1995 to May 2020 was performed using Medline, PsycInfo, and Embase (OVID), Scopus, CINHAL and LGBT Life (EBSCO), combining keywords for bisexuality and alcohol use. Peer-reviewed publications that reported quantitative data on alcohol use among bisexual people were included. A random-effects model was used to pool the prevalence of two outcomes: any alcohol use and heavy episodic drinking (HED). Subgroup analysis and random-effects meta-regression were used to explore heterogeneity.

RESULTS

Of 105 studies eligible for data extraction, the overall prevalence of alcohol use was higher among bisexuals compared to lesbian/gay and heterosexual people. For example, the prevalence of past-month HED was 30.0% (28.2, 31.8) among bisexual people versus 25.5% (23.8, 27.2) among lesbian/gay and 21.3% (19.6, 23.0) among heterosexual individuals. Pooled odds ratio estimates showed that bisexual people were more likely to report alcohol use and HED compared to their counterparts. Gender was a significant effect modifier in meta-regression analysis, with greater disparities among women than among men.

CONCLUSIONS

These results highlight the need for additional research to understand factors underlying bisexual people's greater risk, and particularly bisexual women, as well as alcohol use interventions that are targeted towards the specific needs of bisexual people.

Validation of the Orgasm Rating Scale in Context of Sexual Relationships of Gay and Lesbian Adults

Currently, no validated instrument exists for assessing the subjective experience of orgasm in the gay population. The Orgasm Rating Scale (ORS), previously validated in the heterosexual population, comprises four dimensions: Affective, Sensory, Intimacy, and Rewards. This study validated it for sexual relationships in the gay population by obtaining its factorial invariance by sexual orientation and sex, its internal consistency reliability, and evidence of validity in its relationship with other variables. We assessed 1600 cisgender Spanish adults–heterosexuals, gays, and lesbians–divided into 4, sex-based groups of 400 each, according to the Kinsey scale scores. Participants reported recent experiences of orgasm in the context of sexual relationships and responded to the ORS and other scales assessing attitude toward sexual fantasies and sexual functioning. The ORS structure showed a strict multigroup-level invariance by sexual orientation and sex, confirming its four-dimensional structure. The subjective orgasm intensity was associated with a positive attitude toward sexual fantasies and sexual functioning. Scores obtained on the Affective, Intimacy, and Rewards dimensions confirmed the ability to discriminate between gay people with and without orgasmic difficulties. The ORS’s Spanish version presents good psychometric properties as a validated scale to evaluate the subjective experience of orgasm in the gay population.
