RESUMO

BACKGROUND: Understanding the frequency of violence experienced by female sex workers (FSWs) and how violence contributes to HIV transmission can help improve HIV programs. METHODS: Using recent recommendations for modelling structural factors and associated causal pathways, we developed a HIV transmission dynamic model for FSWs and their clients in Mombasa, Kenya, mechanistically representing three types of violence (sexual violence, SV; physical violence, PV; police assault and arrest, PAA). Each type of violence affects HIV transmission through key mediators (condom non-use, HIV testing). We parameterized the model using data from a cross-sectional study of FSWs aged 15-24 recruited from a systematic geographical mapping sampling frame in Mombasa, Kenya (Cheuk E et al., Frontiers in Reproductive Health 2(7), 2020). Using this model, calibrated (and cross-validated) to HIV epidemiological and violence outcomes, we estimated the incidence of violence episodes, the contribution of violence to the HIV epidemic measured by the transmission population-attributable fraction, and the potential impact of possible violence interventions. RESULTS: The median estimated incidence of PAA in 2023 among FSWs who had not previously experienced that type of violence was 0.20 (95% credible interval: 0.17-0.22) per person-year (ppy), about double the incidence of SV and PV (0.10 (0.09-0.11), 0.11 (0.09-0.12), respectively). The incidence of violence was higher among FSWs who had previously experienced violence: the incidence of recurrent PV was 2.65 (1.82-3.37) ppy, while the incidence of recurrent SV and PAA were 1.26 (0.80-1.67) and 1.37 (0.94-1.74 ppy, respectively. In this setting, we estimated that a median of 35.3% (3.4-55.8%) infections in FSWs and clients combined over the next 10 years may be due to all types of violence (and mediators), mainly through reduced condom use in FSWs who have ever experienced SV (34.6% (2.4-55.5%)). Interventions that prevent future violence without mitigating the effects of past violence may only prevent 8.8% (0.8-14.0%) infections over 10 years. CONCLUSIONS: FSWs in Mombasa experience violence frequently. In this population, we find that addressing sexual violence, including mitigating the effects of past violence, is potentially important in reducing HIV transmission in this population. However, the wide uncertainty range shows longitudinal studies are needed to strengthen the evidence of the influence of violence on HIV risk behavior. We find that the recommendations for modelling structural factors provide a useful framework for describing the model.

RESUMO

The Northwest Territories (NWT), Canada has high rates of sexually transmitted infections (STI) that elevate HIV acquisition risks. We conducted a mixed-methods study to explore the potential of land-based peer leader retreats (PLR) in building HIV prevention enabling environments among Northern and Indigenous youth in the NWT. PLRs are grounded in Indigenous principles and ways of knowing, acknowledging the land as a physical, spiritual, emotional, and intellectual being with the potential to facilitate (re)connection to culture, community, and self. We conducted one-week PLRs between 2016 and 2021 with adolescents aged 13-17 in the NWT. PLRs addressed HIV/STIs, safer sex, and gender equity. We conducted post-retreat focus groups (FGs) and pre/post-retreat surveys with youth participants (n = 353), and post-retreat FGs with PLR facilitators (n = 252). We applied thematic analysis to FGs and assessed pre/post-retreat changes in HIV/STI knowledge and safer sex efficacy (SSE) using paired sample t-tests. We assessed factors associated with post-test SSE and HIV/STI knowledge using multivariable linear regression. Youth participants (n = 353; mean age: 14.5, standard deviation [SD]: 1.3) were mostly Indigenous (71%) and women (66%). Participant narratives revealed PLRs enhanced technical communication (e.g., correct condom use). There were significant post-retreat HIV/STI knowledge increases; change score increases were lower for Indigenous participants. Qualitative narratives described how PLRs fostered transformative communication (e.g., sexual consent). There were significant post-retreat increases in SSE, and these were lower among men and sexually diverse (vs. heterosexual) participants. Land-based PLRs offer the potential to build technical and transformative communication to facilitate HIV prevention with youth in Canada's North.

RESUMO

Pre-exposure prophylaxis (PrEP) reduces sexual risk for HIV transmission by 99% when used appropriately, but remains underutilized among gay, bisexual, and other men who have sex with men (MSM). In this mixed-method study, we describe reasons for PrEP refusal associated with low self-perceived need for PrEP among MSM who recently declined daily oral PrEP when offered by a provider. Data are from a quantitative behavioral survey of MSM (N = 93) living in Atlanta, Chicago, and Raleigh-Durham, who also either responded to an in-depth interview (n = 51) or participated in one of 12 focus groups (n = 42). Themes of low self-perceived need for PrEP were: low self-perceived risk for HIV acquisition (33% of respondents); confidence in remaining HIV-negative (35%); using condoms (81%); limiting number of partners and choosing partners carefully (48%); asking partners about their HIV status before having sex (45%); engaging in safer sexual positions or oral sex (28%); being in a monogamous relationship or exclusivity with one partner (26%); and regular HIV testing (18%). Low self-perceived risk for HIV acquisition and high confidence in other prevention strategies were important factors related to low self-perceived need in MSM refusing daily oral PrEP when offered. Providers should continue to discuss the benefits of PrEP as a safe and highly effective option for HIV prevention.


RESUMEN: La profilaxis pre-exposición (PrEP) reduce el riesgo de transmisión sexual por el VIH en un 99% cuando se utiliza apropiadamente, pero sigue siendo subutilizada entre hombres gais, bisexuales y otros hombres que tienen sexo con hombres (HSH). En este estudio de método mixto, describimos los motivos del rechazo de la PrEP asociados a la baja necesidad autopercibida de la PrEP entre los HSH que recientemente rechazaron la PrEP oral diaria, cuando fue ofrecida por un proveedor de salud. Los datos provienen de una encuesta cuantitativa de comportamiento de los HSH (N = 93) que viven en Atlanta, Chicago y Raleigh-Durham, quienes también respondieron a una entrevista en profundidad (n = 51) o participaron en uno de los 12 grupos focales (n = 42). Los temas de baja necesidad autopercibida del uso de la PrEP fueron: el bajo riesgo auto percibido de contraer el VIH (33% de los encuestados); la confianza en seguir siendo VIH negativo (35%); utilizar condones (81%); limitar el número de parejas sexuales y elegir las parejas cuidadosamente (48%); preguntar a sus parejas sobre su estado de VIH antes de tener relaciones sexuales (45%); participar en posiciones sexuales más seguras o sexo oral (28%); estar en relación monógama o de exclusividad con una sola pareja (26%); y hacerse pruebas del VIH regularmente (18%). El bajo riesgo autopercibido de contraer el VIH y la alta confianza en otras estrategias de prevención fueron factores importantes relacionados con la baja necesidad autopercibida en los HSH que rechazaron la PrEP oral diaria cuando se les ofreció. Los proveedores de salud deben continuar el diálogo sobre los beneficios de la PrEP como una opción segura y altamente eficaz para la prevención del VIH.

RESUMO

Receiving peer advocacy has been shown to result in increased HIV protective behaviors, but little research has gone beyond assessment of the mere presence of advocacy to examine aspects of advocacy driving these effects. With baseline data from a controlled trial of an advocacy training intervention, we studied characteristics of HIV prevention advocacy received among 599 social network members of persons living with HIV in Uganda and the association of these characteristics with the social network members' recent HIV testing (past six months) and consistent condom use, as well as perceived influence of advocacy on these behaviors. Participants reported on receipt of advocacy specific to HIV testing and condom use, as well as on measures of advocacy content, tone of delivery, support for autonomous regulation, and perceived influence on behavior. Receiving HIV testing advocacy and condom use advocacy were associated with recent HIV testing [65.2% vs. 51.4%; OR (95% CI) = 1.77 (1.11-2.84)], and consistent condom use with main sex partner [19.3% vs. 10.0%; OR (95% CI) = 2.16 (1.12-4.13)], respectively, compared to not receiving advocacy. Among those who received condom advocacy, perceived influence of the advocacy was positively correlated with consistent condom use, regardless of type of sex partner; support of autonomous regulation was a correlate of consistent condom use with casual sex partners, while judgmental advocacy was a correlate of consistent condom use with serodiscordant main partners. Among those who received testing advocacy, HIV testing in the past 6 months was positively correlated with receipt of direct support for getting tested. In multiple regression analysis, perceived influence of both HIV testing and condom use advocacy were positively correlated with advocacy that included access information and support of autonomous regulation; confrontational advocacy and judgmental advocacy were independent positive correlates of perceived influence of testing and condom use advocacy, respectively. These findings support associations that suggest potential benefits of peer advocacy from PLWH on HIV testing and condom use among their social network members, and indicate that advocacy content, tone of delivery, and support of autonomous regulation advocacy may play an important role in the success of advocacy.

RESUMO

PrEP has been reported to facilitate openness to serodifferent sexual partnerships among sexual minority men (SMM). However, other aspects of a sexual scenario likely come into play, including whether or not condoms are used and whether or not the partner living with HIV has an undetectable viral load. This online survey study evaluated the association between PrEP status and openness to serodifferent partnering, as well as the effects of various sexual scenario variables (condom use and partner's viral load) among 268 HIV-negative SMM in the US. Each participant reported their PrEP status and rated their openness to serodifferent partnering in four sexual scenarios, which varied by condom use (with/without) and partner viral load status (detectable/undetectable). Analyses of covariance (ANCOVAs) were conducted to assess differences in openness to serodifferent partnering by PrEP status in each scenario, adjusting for background characteristics. A two-way repeated measures ANCOVA and a three-way mixed factorial ANCOVA, including PrEP status as a between-subjects variable, were also performed to assess the effects of condom use and partner viral load status on openness. Across all scenarios, current PrEP users expressed significantly greater openness to serodifferent partnering compared to participants who had never used PrEP. Current PrEP users were also more likely than former PrEP users to consider partnering with someone with an undetectable viral load without using condoms. Both PrEP users and PrEP-inexperienced individuals had greater openness to serodifferent partnering with a partner having an undetectable (vs. detectable) viral load, which was magnified by condom use among the latter.


RESUMEN: Se ha reportado que hombres de minorías sexuales (HMS) están más dispuestos a tener parejas sexuales serodiferentes cuando usan PrEP. Sin embargo, es probable que existan otros aspectos del contexto sexual, como el uso o no de condones y si la pareja que vive con el VIH tiene o no una carga viral indetectable. Este estudio utilizó una encuesta virtual para evaluar la asociación entre el uso de PrEP y el estar abierto a parejas serodiferentes, así como los efectos de diversas variables del contexto sexual (uso de condón y carga viral de la pareja) entre 268 SMM VIH negativos en los EE. UU. Cada participante reportó su uso de PrEP y estimó su apertura a parejas serodiferentes en cuatro contextos sexuales, que variaron según el uso de condón (con o sin) y el estado de carga viral de la pareja (detectable/indetectable). Para examinar si la apertura a tener parejas sexuales serodiferentes estaba asociada con el uso de PrEP en cada contexto sexual, se realizaron análisis de covarianza (ANCOVA), controlando por características demográficas. También se utilizó ANCOVA de medidas repetidas de dos vías y una ANCOVA de diseño factorial mixto de tres vías, incluyendo el estado de PrEP como una variable entre sujetos, para evaluar los efectos del uso de condón y el estado de carga viral de la pareja en la apertura a tener parejas sexuales serodiferentes. En todos los contextos, las personas usando PrEP en ese momento expresaron una apertura significativamente mayor a las parejas serodiferentes comparados con los participantes que nunca habían usado PrEP. Las personas usando PrEP en ese momento también eran más propensas a considerar asociarse con alguien con una carga viral indetectable sin usar condones que los que habían descontinuado PrEP. Tanto los usuarios de PrEP como las personas sin experiencia en PrEP tuvieron una mayor apertura a tener relaciones serodiferentes con una pareja que tuviera una carga viral indetectable (versus detectable), que se magnificó por el uso de condones entre los sin inexperiencia.

RESUMO

In Mozambique, women are the most affected by HIV/AIDS and heterosexual encounters remain the main route for HIV/AIDS. Condom use is the most effective method of HIV/AIDS prevention, and the intention to use and buy/get condoms has a significant role in safe sex behavior. This study aimed to evaluate the efficacy of two psychosocial interventions - the Didactic and ACCENT Interventions - to prevent HIV/AIDS among Mozambican Women. Participants were Mozambican women (n = 150), users of the gynecology clinic of the Central Hospital of Beira. The study design was a randomized controlled trial (RCT) with assignment to three groups: Didactic intervention, ACCENT intervention, and Control group. Measures were from an adaption of the Women's Health Questionnaire, which includes questions about sociodemographic, clinical, and behavioral variables related to HIV prevention/risk. There was a significant group effect on condom use and safer sex preparatory behaviors, F(2, 146) = 6.45, p = .002, with Bonferroni post-hoc tests showing differences between the ACCENT vs. Control groups and ACCENT vs. Didactic groups (all p = .022). There were no statistically significant time effects on both condom use and safer sex preparatory behaviors. Results are promising for HIV/AIDS prevention in Mozambican women at sexual risk, but replication is needed for generalizability of findings.

RESUMO

Past findings on the association between negative body image and sexual health behaviors have been mixed and mostly derived from Western samples. The aim of the current study was to examine associations between indices of negative body image and sexual health practices that reduce the risk of disease transmission in emerging adults, and whether these associations are moderated by gender. Using an online survey, a convenience sample of 584 Malaysian adults aged 18-30 years (230 men, 354 women) completed measures of satisfaction with overall appearance, body size dissatisfaction, weight satisfaction, height satisfaction, and genital image evaluation. They also reported if they ever had partnered sex, condomless sex, and been screened for human immunodeficiency virus (HIV), as well as their lifetime number of penetrative sex partners. Hierarchical logistic and ordinal regression analyses indicated that more positive genital image evaluation, but not the other body image indices, was significantly associated with having had partnered sex and fewer lifetime penetrative sex partners. None of the body image indices were significantly associated with condomless sex. All associations were consistent across men and women. For HIV testing, a significant interaction between genital image evaluation and gender emerged. However, this was reduced to non-significance after controlling for the number of penetrative sex partners. Overall, our findings underline the importance of promoting improved genital image in interventions aimed at increasing positive sexual health behaviors.

RESUMO

Traditional gender role beliefs, or marianismo beliefs, are theorized to be largely protective against health risk behaviors, including sexual risk behaviors among Latina young adults. However, measurement differences across studies and research with heterogeneous samples of abstinent and sexually active Latina young adults have led to unclear findings. Thus, we investigated whether endorsement of certain marianismo beliefs may promote sexual health behaviors or solely promote abstinence. Guided by gender role schema theory, this study investigated the multidimensional construct of marianismo beliefs in relation to past-year abstinence from sexual activity, STI and HIV testing, and condom use among 611 Latina young adults. Results indicated that endorsement of the Virtuous and Chaste belief was associated with decreased odds of sexual activity (i.e., increased odds of being abstinent) in the past year. None of the five marianismo beliefs were significantly linked with condom use. Among sexually active participants, the Virtuous and Chaste belief was associated with decreased likelihood to be tested for both STIs and HIV in the past year. Findings support the notion that certain marianismo beliefs (e.g., the Virtuous and Chaste belief) may promote abstinence, yet pose a risk for sexual health via reduced likelihood for STI and HIV testing. Results may inform culturally-tailored HIV prevention interventions with Latinas to reduce the disproportionate HIV burden in this population.

RESUMO

Pre-exposure prophylaxis (PrEP) use may be associated with condom use decisions. The current investigation examined sexual decision-making in the context of PrEP among young adult men who have sex with men (MSM) between 18 and 30 years old, using an explanatory sequential mixed methods design. For the quantitative aim, 99 MSM currently taking PrEP (i.e., PrEP-experienced) and 140 MSM not currently taking PrEP (i.e., PrEP-naive) completed an online survey, including the Sexual Delay Discounting Task (SDDT), which captures likelihood of condom use. For the qualitative aim, 15 people from each group were interviewed about their (1) conceptualizations of risky sex and (2) ways they manage their sexual risk. Participants were, on average, 25.69 years old (SD = 3.07) and 64% White. Results from the quantitative aim revealed, controlling for covariates, PrEP-experienced participants exhibited significantly lower likelihood of (1) using an immediately available condom and (2) waiting for a delayed condom (i.e., sexual delay discounting) compared to PrEP-naive participants. Qualitative themes explaining what young adult MSM consider to be risky sex included: (1) any sex as risky sex, (2) risky sex as "sex without a conversation," and (3) risky sex as sex with risk for physical harm. Themes on ways young adult MSM manage sexual risk were classified as proactive, reactive, and passive. Results suggest that PrEP use is related to condom use decisions. Taken together, quantitative differences in sexual delay discounting, but qualitatively similar conceptualizations and management of risky sex, suggest that the SDDT may be a useful tool in sex research to capture processes (i.e., delay discounting) underlying sexual decision-making that may be missed by traditional self-reports. Implications of results, including potentially providing (good quality) condoms with every PrEP prescription, and future research topics are discussed.

RESUMO

BACKGROUND: Prior research has consistently shown that the involvement of families plays a vital role in reducing risk behaviors, such as engaging in condomless sex, and promoting HIV prevention behaviors among young Black men who have sex with men (YBMSM). With the aim of expanding the existing knowledge, this study aimed to examine the specific influence of families and other supportive adults in facilitating casual condom use, partner condom use, HIV testing, and preexposure prophylaxis (PrEP) utilization among young Black MSM. METHODS: A sample of YBMSM aged 18-29 years (N = 400) was collected online. We used a path analysis to examine the influence of family factors on PrEP stigma and PrEP use. Respondents were recruited from December 1, 2021, to January 31, 2022. We used a path analysis to examine the direct and indirect effects of family factors on PrEP use through HIV testing and encouraging condom use. RESULTS: Among BMSM, other adult support was positive and directly associated with condom use by both casual partners (ß = 0.04, p < .05) and partners (ß = 0.17, p < .01). Condom use by casual partners was negative and was directly associated with HIV testing (ß = - 0.15, p < .01). CONCLUSION: The primary aim of this research was to examine the influence of family and adult support on HIV prevention behaviors among young Black MSM, including condom use, HIV testing, and PrEP use. Our findings highlight the significance of implementing interventions that incorporate families and other supportive adults to enhance the engagement of young Black MSM in HIV prevention behaviors.

RESUMO

BACKGROUND: Condom use at last intercourse is an effective indicator for human immunodeficiency virus (HIV) prevention. To identify at-risk individuals and improve prevention strategies, this study explored factors associated with condomless sex at last intercourse in the last year and developed a risk estimation model to calculate the individual possibility of condomless sex among college students in Zhuhai, China. METHODS: A cross-sectional study was conducted among 1430 college students who had sex in the last year from six universities in Zhuhai. The least absolute shrinkage and selection operator (LASSO) and logistic regression were performed to explore the predictors of condomless sex. The nomogram was constructed to calculate the individual possibility of condomless sex. Discrimination and calibration of the nomogram were evaluated using the area under the receiver-operator characteristic curve (AUROC) and the calibration curve. RESULTS: The proportion of students who had condomless sex at last intercourse was 18.2% (260/1430). Students who had experienced more types of intimate partner violence (aOR, 1.58; 95% CI, 1.31 ~ 1.92) and had anal sex (aOR, 1.75; 95% CI, 1.06 ~ 2.84) were more likely to have condomless sex. Students who had heterosexual intercourse (aOR, 0.37; 95% CI, 0.21 ~ 0.70), used condoms at first sex (aOR, 0.20; 95% CI, 0.14 ~ 0.27), had high attitudes towards condom use (aOR, 0.87; 95% CI, 0.80 ~ 0.95) and self-efficacy for condom use (aOR, 0.84; 95% CI, 0.78 ~ 0.90) were less likely to have condomless sex. The nomogram had high accuracy with an AUROC of 0.83 and good discrimination. CONCLUSIONS: Intimate partner violence, anal sex, condom use at first sex, attitude towards condom use, and self-efficacy for condom use were associated with condomless sex among college students. The nomogram was an effective and convenient tool for calculating the individualized possibility of condomless sex among college students. It could help to identify individuals at risk and help universities and colleges to formulate appropriate individualized interventions and sexual health education programs.

RESUMO

BACKGROUND: Female sex workers (FSWs) in Mozambique face significant health risks, including high HIV prevalence, combination of factors, including inconsistent condom use, engagement in risky sexual behaviors, and various socio-ecological determinants of health. Understanding the determinants of these practices is crucial for developing targeted interventions. METHODS: This cross-sectional study analyzed data from the second round of Biobehavioral Survey (BBS) conducted from 2019 to 2020 in five urban areas to examine determinants of inconsistent condom use and risky sexual behaviors among FSWs. Modified Poisson regression models were used to assess the effect of various socio-demographic, economic, and behavioral factors on the outcomes, providing adjusted relative risk (aRR) with 95% confidence intervals (CI). RESULTS: Among the 2,565 FSWs who reported inconsistent condom use, younger FSWs (15-24 years old, 29.1%), single (27.3%), with secondary or higher education (26.1%), nationals (25.9%), and residents of Tete City (30.5%) had a higher prevalence of inconsistent condom use. Initiating sex work < 18 years (31.0%), binge drinking (23.7%), and experiencing physical violence (29.0%) were significantly associated with this behavior. Among the 2,564 FSWs reporting risky sexual behaviors, a higher prevalence was observed in FSWs aged 15-24 (75.6%), those with secondary or higher education (75.8%), nationals (74.4%), and those residing in Quelimane (87.3%). Early sexual debut (< 15 years, 79.3%), initiating sex work before 18 years of age (77.7%), and illicit drug use (82.2%) were all associated with increased risky sexual practices. Inconsistent condom use among FSWs was significantly associated with residing in Tete (aRR = 2.4, 95% CI: 1.77-3.25), not being aware of female condom (aRR = 1.22, 95% CI: 1.03-1.45) and having experienced sexual a physical violence. Moreover, being married was significantly linked to risky sexual behavior among female sex workers (aRR = 1.27, 95% CI: 1.19-1.37), along with initiating sexual activity before age 15, having at least five years of sex work experience, engaging in binge drinking, and experiencing sexual and physical violence. CONCLUSION: The study highlights the complex set of factors as age, education, geographic location, years of sex work services, early sexual debut, and illicit drug use that influence sexual risks behavior among FSWs in Mozambique. Tailored interventions addressing not only sexual health education and services, but also economic empowerment and illicit drug use is imperative for mitigating these risks.

RESUMO

BACKGROUND: Risky sexual behavior (RSB) is one of the major youth sexual and reproductive health problems globally, including in Ethiopia. RSB among youth increases the risk of HIV infection, other sexually transmitted infections (STIs), unintended pregnancy, and unsafe abortion. Therefore, the aim of this study was to examine RSB and its associated factors among university students in Ethiopia. METHODS: A cross-sectional study was employed in six randomly selected public universities in Ethiopia from August 2021 to February 2022. A stratified two-stage sampling technique was applied to reach the required number of study participants, and a structured self-administered questionnaire was used. RSB was defined as having had sexual relationships with more than one partner and using condoms with a new sexual partner irregularly or not at all in the last 12 months. Bivariable and multivariable logistic regression analyses were used to identify factors associated with RSB among those participants who were sexually active. RESULTS: The prevalence of RSB among those who had had sexual intercourse in the last 12 months (n = 523) was 19.5% (n = 102). One hundred forty-four (29.9%) students had multiple sexual partners, and 325 (69.3%) students did not always use condoms with a new sexual partner. Adjusted odds ratios (AOR) showed that those students aged 21-24 years had lower odds of RSB than those aged above 25 years AOR 0.18 (95% CI 0.03-0.98). The adjusted odds of RSB were 6.7 times higher (95% CI 1.26-35.30) among students who started sex at the age of 10-17 years than those who started sex at 21 years and above and 3.9 times higher (95% CI 1.33-11.39) among students who had experienced emotional violence. CONCLUSION: RSB continues to be a problem among university students in Ethiopia. Those students who started sex at an early age and those who experienced emotional violence were more likely to engage in RSB. Therefore, universities in Ethiopia should implement strategies such as RSB targeted health education programs that consider early sexual debut, experiences of emotional violence, and safe sexual practices.

RESUMO

BACKGROUND: HIV prevention remains a global priority, especially in sub-Saharan Africa. Our research team previously developed an evidence-based peer group program for HIV prevention called Mzake ndi Mzake (Friend to Friend). A community-engaged collaboration adapted the program for community ownership and implementation. Here we report whether this HIV prevention program, implemented by community volunteers, increased condom use among sexually active individuals in rural Malawi. METHODS: Three communities sequentially rolled out the program. Effectiveness was evaluated using a stepped wedge design. Repeated surveys 11-13 months apart were conducted between 2016 and 2019. At Time 1, no community had offered the intervention. At Time 2, the first community had offered the intervention and two had not (control group). At Time 3, two communities had offered the intervention and one had not (control group). We used two condom use indicators; condom use frequency in the last 2 months (N = 771) and condom use at last sex (N = 880). The analytical sample included all sexually active persons answering that question at one or more time points. Mixed-effects cumulative logit and Generalized Estimating Equation (GEE) models were used to model the two condom indicators over time, controlling for demographic factors, UNAIDS HIV knowledge, safer sex self-efficacy and partner communication. RESULTS: This peer group intervention implemented by trained community volunteers increased both condom use indicators at Times 2 and 3. In the final adjusted models with non-significant factors removed, condom use in the last two months increased for the intervention group vs. control group [Time 2: Adjusted Odds Ratio (AOR) = 1.59 (1.15, 2.21); Time 3: AOR 2.01 (1.23, 3.30)]. Similarly, condom use at last sex increased for the intervention group vs. control group [Time 2: AOR = 1.48 (1.08, 2.03); Time 3: AOR 1.81 (1.13, 2.90)]. Other significant predictors of greater condom use were also described. Although the intervention increased UNAIDS HIV knowledge, knowledge did not predict condom use. CONCLUSIONS: In this community-engaged implementation study, an evidence-based peer group program for HIV prevention increased condom use when delivered by trained community volunteers. Community ownership and program delivery by trained volunteers offer an innovative and cost-effective strategy to address ongoing HIV prevention needs without overburdening healthcare systems in sub-Saharan Africa.

RESUMO

BACKGROUND: Lesotho's government has shown consistent efforts to implement social protection programmes. However, while recent evidence established a positive causal relationship between some of these programmes and food security there is little evidence on the extent to which these initiatives are associated with better educational and sexual and reproductive health outcomes among vulnerable adolescents in Lesotho. METHODS AND FINDINGS: The study uses cross-sectional, nationally representative data from the 2018 Lesotho Violence Against Children and Youth Survey. Our research examined the association between social protection receipt and educational and sexual and reproductive health outcomes among adolescents and young people (13-24 years) living in poverty. We employed multivariate logistic regression controlling for age, orphanhood, HIV status and sex. Social protection receipt was defined as household receipt of financial support from a governmental, non-governmental, or community-based program that provides income. Additionally, we fitted a marginal effects model by sex. Among the 3,506 adolescent females and males living in the two lowest poverty quintiles, receipt of social protection was associated with improvements in multiple adolescent outcomes: higher odds of consistent condom use (aOR 1.64, 95% CI 1.17-2.29), educational attainment (aOR 1.79, 95% CI 1.36-2.36), and school enrolment (aOR 2.19, 95% CI 1.44-3.34). Stratified analyses by sex showed that social protection receipt was also associated with reduced likelihood of child marriage among females (aOR 0.59, 95% CI 0.42-0.83) and higher odds of educational attainment and school enrolment among males (aOR 2.53, 95% CI 1.59-4.03 and aOR 3.11, 95% CI 1.56-6.19, respectively). CONCLUSIONS: Our study provides evidence that social protection programs are associated with improved educational, sexual and reproductive health and child marriage prevention outcomes among adolescents living in poverty. Implementing and expanding such social protection initiatives could prove instrumental in improving the well-being of vulnerable adolescents. CONTRIBUTIONS: Social protection programs have been increasing in sub-Saharan African countries, playing a pivotal role in poverty reduction, with Lesotho being no exception. Despite the optimistic outlook brought about by the implementation of the National Social Protection Strategy Lesotho I (2014-19) and II (2021-2031), the impact of these programs on some specific outcomes that concern the lives of the most vulnerable adolescents in Lesotho remains to some extent unexplored. Additionally, Lesotho grapples with high rates of HIV, adolescent pregnancy, child marriage and early school dropout, which can further contribute to poor long-term health and social outcomes among adolescents. In this study, we used data from the 2018 Lesotho Violence Against Children and Youth Survey (VACS) to examine the association between receiving social protection and multiple adolescent outcomes: educational, sexual and reproductive. The findings revealed that social protection programs, particularly the existing government-provided cash transfers, are significantly associated with multiple better outcomes among adolescents living in the poorest households in Lesotho. Such cash transfer schemes in Lesotho are associated with improved sexual and reproductive health outcomes for adolescent females, including reduced child marriage rates, and improved educational outcomes for males. These findings indicate that government-led social protection programmes are positively associated with favourable outcomes that can improve the quality of life for adolescents in resource-limited settings.

RESUMO

Gonorrhoea cases increased steeply in women aged 20 to 24 years across 15 EU/EEA countries in July to December 2022 and January to June 2023 with, respectively, 73% and 89% more cases reported than expected, based on historical data from 2015 to 2019. Smaller increases among men due to heterosexual transmission were observed in nine EU/EEA countries. Interventions to raise awareness among young people about sexually transmitted infection risks are needed, emphasising the benefit of safe sexual practices and testing.

RESUMO

Black sexually minoritized men (SMM) and transgender women (TW) are subgroups with lower rates of substance use and comparable rates of condom use relative to White SMM and TW yet experience heightened vulnerability to HIV. This study sought to explore associations of substance use, including sex-drug use (i.e., drug or alcohol use during sex to enhance sex), and condomless sex among Black SMM and TW. Data were collected from Black SMM and TW living in Chicago, Illinois, enrolled in the Neighborhoods and Networks (N2) cohort study, from November 2018 to April 2019. We used bivariate analyses followed by a multilevel egocentric network analysis to identify factors associated with condomless sex. We conducted Spearman correlation coefficients to examine correlations between pairs of sex-drugs to enhance sex. We used a bipartite network analysis to identify correlates of sex-drug use and condomless sex. A total of 352 Black SMM and TW (egos) provided information about 933 sexual partners (alters). Of respondents, 45% reported condomless sex and 61% reported sex-drug use. In unadjusted analyses, marijuana (34%) and cocaine/crack (5%) sex-drug use were associated with condomless sex (p < 0.05). Condomless sex was positively associated with sex-polydrug use, or the use of 2+ drugs or 1 drug and alcohol (OR = 1.48; 95% CI: 1.02-2.14; p = 0.039), and negatively associated with sharing an HIV-negative serostatus with a sexual partner (OR = 0.57; 95% CI: 0.33-0.98; p = 0.041), having a different HIV serostatus with a sexual partner (OR = 0.37; 95% CI: 0.21-0.64; p < 0.001) or not knowing the HIV serostatus of a sexual partner (OR = 0.47; 95% CI: 0.26-0.84; p = 0.011). The following pairs of sex-polydrug use had Spearman correlation coefficients higher than 0.3: marijuana and alcohol, ecstasy and alcohol, cocaine/crack and ecstasy, and methamphetamine and poppers (p < 0.05). HIV prevention interventions for Black SMM and TW designed to reduce HIV transmission through egocentric sexual networks could address sex-drug use through sex-positive and pleasure-centered harm reduction strategies and provide and promote biomedical prevention and care options at supraoptimal levels.

RESUMO

OBJECTIVE: To explore their perceptions and attitudes toward condom use and the underlying reasons for the low usage frequency among Chinese older adults. METHODS: A qualitative study design utilizing interpretive phenomenological analysis was employed. Data were collected through field observation and face-to-face in-depth interviews among older adults aged 50 years or above and having engaged in sexual activities within the previous year. RESULTS: Three main themes emerged: perceiving unnecessary due to misconceptions and low awareness, interactive stereotypes rooted in sociocultural beliefs, and stigmatized social norms including gender inequity and economic unbalance. CONCLUSIONS: Tailored interventions focusing on addressing misconceptions, increasing awareness, and reducing culturally ingrained stereotypes and stigma surrounding condom use are essential to promote condom use among older adults in order to prevent HIV transmission in China.

RESUMO

This paper assessed gender differences and perceptions towards condom use among in-school adolescents in Ebonyi State, Nigeria. This was a cross-sectional study undertaken in six local government areas in Ebonyi State, Nigeria. Data were collected using a structured questionnaire and summarised using frequencies and proportions. Chi-square test and binary logistic regression were used in the analysis. The level of statistical significance was a p-value of <0.05. Findings showed that a significantly higher proportion of male respondents (58.8%) had a good perception of condom use when compared to female respondents (45.8%). Gender, level of schooling, and working for pay had significant associations with good perceptions of condom use, while the significant predictors in the logistic regression model were gender, level of schooling, and working for pay. Interventions that promote the sexual and reproductive health and rights of adolescents and those that empower women with relevant skills by addressing unequal gender power relations in relationships should be prioritized.


Cet article a évalué les différences entre les sexes et les perceptions concernant l'utilisation du préservatif parmi les adolescents scolarisés dans l'État d'Ebonyi, au Nigeria. Il s'agissait d'une étude transversale entreprise dans six zones de gouvernement local de l'État d'Ebonyi, au Nigeria. Les données ont été collectées à l'aide d'un questionnaire structuré et résumées à l'aide de fréquences et de proportions. Le test du chi carré et la régression logistique binaire ont été utilisés dans l'analyse. Le niveau de signification statistique était une valeur p <0,05. Les résultats ont montré qu'une proportion significativement plus élevée d'hommes interrogés (58,8 %) avaient une bonne perception de l'utilisation du préservatif par rapport aux femmes interrogées (45,8 %). Le sexe, le niveau de scolarité et le travail rémunéré étaient associés de manière significative à de bonnes perceptions de l'utilisation du préservatif, tandis que les prédicteurs significatifs dans le modèle de régression logistique étaient le sexe, le niveau de scolarité et le travail rémunéré. Les interventions qui promeuvent la santé et les droits sexuels et reproductifs des adolescents et celles qui donnent aux femmes les compétences nécessaires en s'attaquant aux relations de pouvoir inégales entre les sexes dans les relations devraient être prioritaires.

RESUMO

Artisanal and small-scale mining (ASM) is a significant source of income for tens of millions of people worldwide. Consistent condom use is pivotal in the prevention of HIV/AIDS and other STIs. This study assessed sexual behaviors and factors associated with consistent condom use among young male artisanal miners in Kassanda District, Uganda. A cross-sectional survey was conducted with 304 miners aged 15-24 years. Data -analysis included frequency distributions, chi-squared tests, and binary logistic regression. 89% had sexual intercourse in the past year, 55% had multiple partners, 11% engaged in transactional sex, and only 42% used condoms consistently. Married/cohabiting young men (OR=0.41; CI=0.19-0.87), those with a neutral attitude towards condom use (OR=0.30; CI=0.11-0.85), and those with only their mothers as parents (OR=0.37; CI=0.19-0.73) were less likely to use condoms consistently. The study highlights the need for targeted interventions promoting condom use among married young men and those raised by single mothers to reduce the risk of STI transmission.


L'exploitation minière artisanale et à petite échelle (ASM) constitue une source de revenus importante pour des dizaines de millions de personnes dans le monde. L'utilisation systématique du préservatif est essentielle à la prévention du VIH/SIDA et d'autres IST. Cette étude a évalué les comportements sexuels et les facteurs associés à l'utilisation systématique du préservatif chez les jeunes mineurs artisanaux du district de Kassanda, en Ouganda. Une enquête transversale a été menée auprès de 304 mineurs âgés de 15 à 24 ans. L'analyse des données comprenait des distributions de fréquences, des tests du chi carré et une régression logistique binaire. 89 % ont eu des rapports sexuels au cours de l'année écoulée, 55 % ont eu plusieurs partenaires, 11 % se sont livrés à des relations sexuelles transactionnelles et seulement 42 % ont utilisé des préservatifs de manière constante. Jeunes hommes mariés/cohabitants (OR=0,41 ; IC=0,19-0,87), ceux ayant une attitude neutre à l'égard de l'utilisation du préservatif (OR=0,30 ; IC=0,11-0,85) et ceux dont la mère est seule comme parent (OR=0,37 ; IC=0,19-0,73) étaient moins susceptibles d'utiliser régulièrement des préservatifs. L'étude souligne la nécessité d'interventions ciblées promouvant l'utilisation du préservatif parmi les jeunes hommes mariés et ceux élevés par des mères célibataires afin de réduire le risque de transmission des IST.
