Factors Associated with Condom Use in Anal Intercourse Among Spanish Men Who Have Sex with Men: Proposal for an Explanatory Model

Alcohol Use Disorder and HIV Risk in a National Survey of Men Who Have Sex with Men in Ukraine

BACKGROUND

Problematic alcohol consumption is associated with risk behaviors associated with HIV transmission. Despite the high prevalence of problematic alcohol consumption in Ukraine, however, there are little empirical data examining its association with risk behaviors also associated with HIV transmission in men who have sex with men (MSM), a key population where HIV incidence is increasing, METHOD: Correlates of prevalent HIV infection and their association between drinking severity levels and behaviors also associated with increased likelihood of HIV acquisition were analyzed from a 2017 nationally representative survey (IBBS) of 4938 MSM in Ukraine using bivariate analyses and multivariate regression.

RESULTS

Overall, 42.6% of MSM participants met screening criteria for alcohol use disorder (AUD), with 24.2%, 12.0%, and 6.3% meeting criteria for moderate, high, and severe risk of harm from alcohol consumption, respectively. Multivariate regression revealed that these risk categories were correlated with behaviors associated with increased HIV transmission risk, including reports of (1) > 5 sexual partners; (2) sex with a partner of unknown HIV status; (3) sex work; (4) any drug use; and (5) not testing for HIV (past year). HIV testing was infrequent, with only 44.1% having been tested in the previous year.

CONCLUSION

The high prevalence of problematic alcohol use in Ukrainian MSM and its association with behaviors also associated with HIV transmission supports the importance of routine screening of MSM for AUD. Moreover, among those screening positive for a potential AUD, targeted HIV prevention strategies to scale-up pre-exposure prophylaxis, consistent condom use, and treatment for AUD are needed.

Perceived risk for HIV acquisition and sexual HIV exposure among sexual and gender minorities: a systematic review

We conducted a systematic review to explore the relationship between perceived risk for HIV acquisition and sexual HIV exposure among sexual and gender minorities. We included 39 studies divided into (i) correlations or associations, (ii) models using sexual HIV exposure as the outcome, and (iii) models using perceived risk for HIV acquisition as the outcome. The sample size range was from 55 to 16,667 participants, primarily cisgender men who have sex with men (73.3%) and White (51.3%). Sexual HIV exposure and perceived risk for HIV acquisition assessments and recall time frames across studies differed markedly. Most of studies (84.6%) found significant correlations, comparisons, or associations between different levels of perceived risk for HIV acquisition and high sexual HIV exposure. In addition, 51.3% of studies reported other variables associated with high sexual HIV exposure (i.e., misuse of substances or alcohol) or with high perceived risk for HIV acquisition (i.e., younger age). In conclusion, the association between perceived risk for HIV acquisition and sexual HIV exposure has shown to be consistent. However, the assessment for perceived risk for HIV acquisition should include more components of perception (i.e., an affective component), or for sexual HIV exposure should consider the different estimated sexual per-acts probability of acquiring HIV.

Inconsistent use of male condoms among HIV-negative men who have sex with other men

OBJECTIVE

to analyze the factors associated with inconsistent use of male condoms among HIV-negative men who have sex with other men.

METHOD

a cross-sectional, analytical and nationwide study conducted online in all the Brazilian regions in 2020, via networks and in dating websites. Inconsistent condom use was defined as occasional use or as never using it. Descriptive statistical analyses were performed, as well as association and binary logistic regression tests.

RESULTS

inconsistent condom use was reported by 1,222 (85%) of all 1,438 participants. The "homosexuals" (ORAdj: 2.03; 95% CI: 1.14-3.59; p=0.016), "having a fixed partner" (ORAdj: 2.19; 95% CI: 1.55-3.09; p<0.001), "oral sex" (ORAdj: 2.41; 95% CI: 1.31-4.43; p=0.005), "insertive anal" (ORAdj: 1.98; 95% CI: 1.10-3.58; p=0.023) and "STI diagnosis" (ORAdj: 1.59; 95% CI: 1.13-2.24; p=0.007) variables were independently associated with inconsistent use of male condoms. The "receiving advice on HIV test from a friend" (ORAdj: 0.71; 95% CI: 0.52-0.96; p=0.028) and "sex worker" (ORAdj: 0.26; 95% CI: 0.11-0.60; p=0.002) variables were protective factors.

CONCLUSION

the variables under study pointed to a strong relationship between steady partners and increased trust and low adherence to condom use, corroborating other studies.

Prevalence of unprotected anal intercourse and associated factors among male students who have sex with men in Qingdao, China: A cross-sectional study

The significant rise of human immunodeficiency virus (HIV) epidemic among young students has become a new feature of acquired immune deficiency syndrome in China, and unprotected anal intercourse (UAI) among male students who have sex with men (SMSM) played a central role in this process. The aim of this study was to investigate the prevalence of UAI, as well as analyze the factors associated with UAI among SMSM in Qingdao, China. From May 2021 to April 2022, men who aged 15 to 30, studied in a high school or college in Qingdao and had anal sex with men in the past 6 months were recruited through snowball method relying on the nongovernmental organization. An anonymous electronic questionnaire was administrated to collect information on socio-demographic characteristics, sexual behaviors, substance use before sex, HIV prevention services and self-esteem. Univariate and multivariate logistic regressions were used to assess factors related to UAI. Among the 341 SMSM included in the study, 40.5% engaged in UAI in the past 6 months. Being migrants from other provinces [odds ratios (OR) = 2.04, 95% confidence intervals (CI): 1.10-3.78], failing to use condoms for the first anal intercourse (OR = 3.38, 95% CI: 1.85-6.18), drinking alcohol before sex (OR = 2.31, 95% CI: 1.25-4.28) and being low level self-esteem (OR = 1.77, 95% CI: 1.09-2.87) were positively associated with UAI. SMSM who had homosexual intercourse more than once a week (OR = 1.76, 95% CI: 1.03-3.00) or had multiple male sex partners (OR = 1.99, 95% CI: 1.20-3.30) were more likely to engage in UAI. Received peer education in the past 12 months (OR = 0.48, 95% CI: 0.27-0.86) was associated with lower odds of UAI. The situation of UAI among SMSM in Qingdao was a public health issue of concern. It is necessary to take targeted measures, such as focusing on first-time sex, advancing sexual health education, expanding peer education, implementing alcohol use screening and maintaining the self-esteem of SMSM, so as to reduce the occurrence of high-risk behaviors among SMSM and curb the spread of HIV on campus.

Predicting the risk of HIV infection among internal migrant MSM in China: An optimal model based on three variable selection methods

Introduction

Internal migrant Men who have sex with men (IMMSM), which has the dual identity of MSM and floating population, should be more concerned among the vulnerable groups for HIV in society. Establishing appropriate prediction models to assess the risk of HIV infection among IMMSM is of great significance to against HIV infection and transmission.

Methods

HIV and syphilis infection were detected using rapid test kits, and other 30 variables were collected among IMMSM through questionnaire. Taking HIV infection status as the dependent variable, three methods were used to screen predictors and three prediction models were developed respectively. The Hosmer-Lemeshow test was performed to verify the fit of the models, and the net classification improvement and integrated discrimination improvement were used to compare these models to determine the optimal model. Based on the optimal model, a prediction nomogram was developed as an instrument to assess the risk of HIV infection among IMMSM. To quantify the predictive ability of the nomogram, the C-index measurement was performed, and internal validation was performed using bootstrap method. The receiver operating characteristic (ROC) curve, calibration plot and dynamic component analysis (DCA) were respectively performed to assess the efficacy, accuracy and clinical utility of the prediction nomogram.

Results

In this study, 12.52% IMMSMs were tested HIV-positive and 8.0% IMMSMs were tested syphilis-positive. Model A, model B, and model C fitted well, and model B was the optimal model. A nomogram was developed based on the model B. The C-index of the nomogram was 0.757 (95% CI: 0.701-0.812), and the C-index of internal verification was 0.705.

Conclusions

The model established by stepwise selection methods incorporating 11 risk factors (age, education, marriage, monthly income, verbal violence, syphilis, score of CUSS, score of RSES, score of ULS, score of ES and score of DS) was the optimal model that achieved the best predictive power. The risk nomogram based on the optimal model had relatively good efficacy, accuracy and clinical utility in identifying internal migrant MSM at high-risk for HIV infection, which is helpful for developing targeted intervention for them.

Internalized homophobia and sexual risk behavior in men who have sex with men: The mediational role of sexual self-concept

Men who have sex with men (MSM) are one of the populations most likely to be infected with human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) worldwide. Sexual risk behaviors (SRB) are the main route of HIV transmission. Among the factors associated with SRB, internalized homophobia (rejection of one’s sexuality) is a risk factor unique for MSM. However, how this factor influences SRB is not clear. Therefore, the present study attempts to clarify the mechanism of action of the relationship between internalized homophobia on SRB based on the mediating effects of sexual self-concept. A study was conducted with 124 MSM living in Chile over 18 years of age (M = 24.4 and SD = 4.19). Through path analysis, it was observed that internalized homophobia has slight inverse effects on SRBs (multiple sexual partners and sexual activity under the influence of alcohol or drugs) when the sexual self-efficacy dimension acts as a mediating variable. These findings suggest that developing sexually transmitted infections (STIs) and HIV/AIDS prevention campaigns focused on MSM must highlight the development of a healthy sexual self-concept and address self-stigma.

Psychological Factors and Sexual Risk Behaviors: A Multidimensional Model Based on the Chilean Population

Human immunodeficiency virus (HIV) is a global health problem, with sexual risk behaviors (SRB) being the main routes of spreading the virus. Evidence indicates that different psychological factors influence SRB (e.g., attitude towards condoms, sexual self-concept, sexual sensation seeking, knowledge of sexual risk behaviors, risk perception). This study proposes an explanatory model of sexual risk behaviors in young people and adults. The sample consisted of 992 young people and adults aged between 18 and 35 years. The model presented good levels of fit (X² = 3311.433, df = 1471, CFI = 0.964, TLI = 0.959, RMSEA = 0.036), explaining 56% of the variance of sexual activity with multiple partners, 77% of the inadequate use of protective barriers, and 58.8% of sexual activity under the influence of alcohol or drugs from a set of psychological factors in self-report measures. The details of the results offer novel contextual evidence for the prioritization of prevention-oriented psychosocial interventions.
