Factors associated with casual sexual behavior among college students in Zhejiang Province, China: A cross-sectional survey.

This study aimed to analyze the characteristics and risk factors associated with casual sexual behavior among sexually active college students and to contribute to AIDS prevention and control efforts among this demographic. A cross-sectional survey was conducted using a stratified cluster sampling technique. Self-reported sexually active college students were selected as respondents from 11 cities in Zhejiang Province from October 8 to November 30, 2018. A questionnaire was used to collect variables such as demographic information, sexual attitudes, intervention acceptance, and self-efficacy of condom use. Univariate and multivariate analyses were performed. Among 3,771 college students who reported engaging in sexual activity, 675 (17.90%) reported engaging in casual sexual encounters. The multivariate analysis revealed multiple factors associated with casual sexual behavior among students: being male, originating from a city/town, having pursued HIV testing education in the last year, seeking HIV risk self-assessment within the last year, accepting to engage in one-night stand behavior, accepting to partake in commercial sexual activity, having conducted HIV antibody tests within the last year, homosexual partner or homosexual/heterosexual partner, demonstrating self-efficacy in condom usage, and monthly living expenses falling within the range of 1001-1500 yuan. Additionally, students with knowledge that appearance does not determine HIV infection, a proclivity for seeking HIV counseling and testing following high-risk sexual behavior and awareness that the centers for disease control provides HIV diagnosis were found to have significant associations with casual sexual activity. Casual sex is significantly prevalent among college students, with male, students from urban areas, those who accepted to engage in one-night stand behavior and partook in commercial sexual activity demonstrating a higher propensity for such behavior. This tendency can be attributed to several factors including a more liberal sexual attitude, a rudimentary understanding of HIV risk, and a low adoption rate of HIV testing. Therefore, it is imperative to enhance HIV prevention and education among college students.

Advancing Programme Science approaches to understand gaps in HIV prevention programme coverage for key populations in 12 Nigerian states: findings from the 2020 Integrated Biological and Behavioural Surveillance Survey.

INTRODUCTION: Effective HIV prevention programme coverage is necessary to achieve Nigeria's goal of ending the epidemic by 2030. Recent evidence highlights gaps in service coverage and utilization across the country. The Effective Programme Coverage framework is a Programme Science tool to optimize a programme's population-level impact by examining gaps in programme coverage using data generated through programme-embedded research and learning. We apply the framework using Integrated Biological and Behavioural Surveillance Survey (IBBSS) data from Nigeria to examine coverage of four prevention interventions-condoms, HIV testing, and needle and syringe programmes (NSP)-among four key population groups-female sex workers (FSW), men who have sex with men (MSM), people who inject drugs (PWID) and transgender people. METHODS: Data from Nigeria's 2020 IBBSS, implemented in 12 states, were analysed to examine HIV prevention programme coverage among key populations. For each key population group and prevention intervention of interest, weighted IBBSS data were used to retrospectively generate coverage cascades that identify and quantify coverage gaps. Required coverage targets were informed by targets articulated in Nigeria's National HIV/AIDS Strategic Framework or, in their absence, by guidelines from policy normative bodies. Availability-, outreach- and utilization coverage proxy indicators were defined using variables from IBBSS data collection tools. Sankey diagrams are presented to visualize pathways followed by participants between coverage cascade steps. RESULTS: Required coverage targets were missed for HIV testing and NSP among all key population groups. Condom availability coverage surpassed required coverage targets among FSW and MSM, while utilization coverage only among FSW exceeded the 90% required coverage target. Outreach coverage was low for all key population groups, falling below all required coverage targets. CONCLUSIONS: Our findings identify critical gaps in HIV prevention programme coverage for key populations in Nigeria and demonstrate non-linear movement across coverage cascades, signalling the need for innovative solutions to optimize coverage of prevention services. Programme-embedded research is required to better understand how key population groups in Nigeria access and use different HIV prevention services so that programmes, policies and resource allocation decisions can be optimized to achieve effective programme coverage and population-level impact.

Exploring patterns and determinants of premarital sexual behaviour among Indonesian university students.

This study is aimed to explore the patterns and determinants of premarital sexual behaviour among Indonesian university students. The research was conducted by online survey, a cross-sectional approach (530 students). Research variables include knowledge, attitudes, practices, and demographic variables. Data were analyzed descriptively, using the Chi-Square test, Fisher Exact Test, and logistic regression to investigate the factors associated with premarital practices. The average age of respondents is 19 years old, with a small portion exposed to pornography. The primary source of pornography exposure is online, with the majority of respondents having good knowledge. Half of the respondents have a positive attitude towards reproductive health. A small portion of respondents have engaged in premarital sex, without using condoms, and have changed partners. In addition, exposure to pornography was significantly associated with premarital sexual practice (p=0.000). Collaboration among stakeholders (university, NGOs, lecturers, and students) is needed to enhance students' knowledge, attitudes, and behaviors regarding reproductive health to prevent premarital sexual practices among university students.

Cette étude vise à explorer les modèles et les déterminants du comportement sexuel avant le mariage chez les étudiants universitaires indonésiens. La recherche a été menée par enquête en ligne, une approche transversale (530 étudiants). Les variables de recherche comprennent les connaissances, les attitudes, les pratiques et les variables démographiques. Les données ont été analysées de manière descriptive, à l'aide du test du Chi carré, du test exact de Fisher et de la régression logistique pour étudier les facteurs associés aux pratiques prénuptiales. L'âge moyen des répondants est de 19 ans, avec une petite partie exposée à la pornographie. La principale source d'exposition à la pornographie est en ligne, la majorité des personnes interrogées en ayant de bonnes connaissances. La moitié des personnes interrogées ont une attitude positive envers la santé reproductive. Une petite partie des personnes interrogées ont eu des relations sexuelles avant le mariage, sans utiliser de préservatifs, et ont changé de partenaire. De plus, l'exposition à la pornographie était significativement associée à la pratique sexuelle avant le mariage (p = 0,000). La collaboration entre les parties prenantes (université, ONG, professeurs et étudiants) est nécessaire pour améliorer les connaissances, les attitudes et les comportements des étudiants en matière de santé reproductive afin de prévenir les pratiques sexuelles avant le mariage parmi les étudiants universitaires.

Changes in contraceptive behavior in Czechia.

The rapid increase in the proportion of women using hormonal contraception in the 1990s was positively reflected in a rapid decline in the number of abortions. Czechia was unique not only among Eastern European countries, but also worldwide. At the same time the decline in the prevalence of hormonal contraception from a peak of almost 50 % in 2007 to 30 % in 2021 meant a slowing and gradual halt in the further decline in abortions. The results of the GGP 2020-2022 survey in Czechia showed that the lower use of hormonal contraception among women was only partly offset by the increased use of other reliable methods of protection against unintended pregnancy (e.g. condom use). The largest decline in the use of hormonal contraceptives in the form of the pill occurred among the youngest women aged 18-27 years, from 76 to 37 %, which was partly reflected in the more intensive use of condoms (an increase from 21 to 35% in the 18-27 age group), but is worrying, that this age group saw the largest increase in the use of less reliable methods (withdrawal from 11 to 22 % and an increase in the use of the barren days method from 1 to 6 %) and also the largest increase in the proportion of women using neither method (from 7 to 17 %). The lowest proportion of female hormonal pill users was found among female with higher education. However an important finding is that when less reliable methods are used, there is an effort to combine at least two methods. Women have a more important role in determining how to protect themselves from unintended pregnancy.

Condom use across casual and committed relationships: The role of relationship characteristics.

BACKGROUND: While the existence of a complex variety of casual sexual relationships (CSRs) has been acknowledged, studies rarely describe the prevalence of condom use across these relationships or how their hybrid nature, specifically relationship characteristics, affect condom use. This study aims to describe condom use within committed relationships and various types of casual sexual relationships (CSRs), examining the influence of relationship characteristics on condom use among culturally validated relationship types (committed, friends with benefits, hookups, booty call). METHODS: Emerging adults (N = 728, 18-29 years, M = 22.56; SD = 3.01) completed a survey with four blocks: sociodemographics; brief sexual history; relationships over the previous year; and current relationship, assessing relationship type, ten relationship characteristics (e.g., commitment, emotional and sexual exclusivity, partner acquaintance, sexual involvement) and condom use (vaginal, oral, and anal), operationalized by three measures (use at last encounter, likert-type scale and percentage of use). RESULTS: The results showed patterns in condom use by relationship type and illuminated how relationship characteristics-grouped into three factors: commitment, intimacy, and sexuality-mediate condom use. Condom use was more frequent in vaginal than anal and oral sex, and less frequent in committed relationships. No significant differences were found in condom use in vaginal sex between committed relationships and hookups, with condom in these relationships being significantly lower than in booty call. Intimacy mediated between all contrasts tested and condom use in vaginal sex, while sexuality mediated between committed vs. CSRs and condom use in anal and oral sex. CONCLUSIONS: Findings point to the need of considering the diversity of CSRs for understanding condom use and highlight the role of intimacy as a relevant mechanism associated with condom use in vaginal sex and of sexuality in oral and anal sex, which should be taken into consideration in the tailoring of health promoting efforts.

Measuring HIV outcomes for adolescent girls and young women programs in Africa: Using the polling booth survey technique.

INTRODUCTION: Adolescent girls and young women (AGYW) remain highly vulnerable to the risk of acquiring HIV (Human immunodeficiency virus). This study was conducted to measure behavioral, biomedical and structural outcomes for the Global Fund funded AGYW programmes in five African countries with high burden of HIV including Botswana, Cameroon. Lesotho, Malawi and Namibia. METHODS: The study used a mixed methods approach to collect behavioral, structural and biomedical outcome data. Quantitative data were collected through 418 Polling Booth Survey (PBS) sessions from 4,581 AGYWs. Participants were recruited through a community-based multistage sampling technique using sampling weights for urban and rural communities. 23 Focus Group Discussions (FGD) were conducted to understand barriers to use of HIV prevention programme and community recommendations for improved coverage. Ethical approvals were obtained from the ethics review board in all five countries. RESULTS: More than 50% of the respondents from all five countries reported to be sexually active, and at least 30% or more of those who were sexually active had multiple sex partners. There were wide variations between the countries in condom use with a non-marital sexual partner which ranged between 66% in Namibia to 42% in Cameroon. Cameroon (44%) had high percentage of AGYWs with independent income source while school drop-outs were higher in Malawi (55.5%) and Lesotho (46.6%). Nearly 1/4th of AGYWs in all countries, except Namibia, reported experiencing intimate partner violence. Nineteen percent of the respondents were pregnant in the last 12 months, and 50% of those pregnancies were unplanned. Lesotho had the highest proportion of AGYW (90.5%) ever tested for HIV, followed by Malawi (87.5%), Botswana (75%), Cameroon (69%) and Namibia (62.6%). DISCUSSION: There is diversity across the countries, with country-wise and age-wise variations in results. In all countries, the AGYW programme will benefit from a more targeted approach to reach out to the most vulnerable AGYW, strengthening structural interventions, strengthening linkage to PrEP (Pre-Exposure Prophylaxis) and ART (Antiretroviral Therapy) for those who are living with HIV and a strong linkage with reproductive health services. The assessment helped countries to understand the gaps and opportunities to improve the HIV prevention programme with AGYW.

HIV status and contraceptive use in Zimbabwe among sexually active adolescent girls and women: Secondary analysis of Zimbabwe Demographic Health survey data.

BACKGROUND: Understanding the pattern of contraceptive use among women living with HIV is critical for formulating relevant public health interventions to improve the uptake and use of reliable methods in this population. This helps to reduce the incidence of unintended pregnancies. OBJECTIVE: In this secondary data analysis, we aimed to describe contraceptive use by HIV-positive and HIV-negative sexually active adolescent girls and women, using data from the Zimbabwe Demographic and Health Survey (2015-16). METHOD: We used statistical analysis to determine the association between the use of various methods of contraception and HIV status using the Zimbabwe Demographic and Health Survey, 2015-16 data. RESULTS: Overall, the contraceptive use prevalence in this study was 60%. Sexually active adolescent girls and women on the Pill and injections were less likely to be HIV-positive compared with those not using any method of contraception (odds ratio (OR)=0.54, 95% confidence interval (CI) (0.45 - 0.64), p=0.001; and OR=0.75, 95% CI (0.59 - 0.96), p=0.020, respectively). Those using either a male or female condom were more likely to be HIV-positive, OR=3.36, 95% CI (2.63 - 4.28), p=0.001. CONCLUSIONS: This study revealed that there is still a considerable unmet need for contraception among the study population, highlighting the need to devise strategies to increase contraception uptake among women. Statistically significant differences were noted in the use of condoms, with those who are HIV-positive having a higher use of condoms compared with those who are HIV-negative. This may reflect that HIV-positive individuals have received appropriate counselling messages on the need to use barrier methods.

"I Don't Believe That One": A Qualitative Study of Undetectable = Untransmittable Views Among Older Adults Living With HIV in South Carolina.

ABSTRACT: Undetectable = Untransmittable (U = U) means that people with HIV who achieve and maintain an undetectable viral load have effectively zero risk of sexually transmitting the virus to others. However, research on how U = U is perceived by older adults living with HIV (OAH) is currently lacking. This study explored U = U views among OAH. From October 2019 to February 2020, we conducted open-ended interviews with 24 OAH recruited at an HIV clinic in South Carolina. Interviews were audio-recorded and transcribed. We employed thematic analysis in this study. Three themes emerged from the analysis: (a) Conflicting beliefs in U = U; (b) Use condoms regardless; and (c) Fear of HIV reinfection. Despite strong scientific evidence supporting U = U, some OAH do not believe in U = U. This lack of belief could deprive OAH of the benefits U = U offers. Therefore, it is vital to educate OAH about U = U to enhance their understanding and belief in U = U.

Association Between Early Sexual Debut and New HIV Infections Among Adolescents and Young Adults in 11 African Countries.

We investigated the association between early sexual debut and HIV infection among adolescents and young adults. Analyzing data from nationally representative Population-Based HIV Impact Assessment (PHIA) surveys in 11 African countries, the research employed a multivariate logistic regression model to assess the relationship between the early sexual debut and new HIV infections in the age group of 10-24 years. The results revealed a significant and robust association, indicating that young individuals who experienced early sexual debut were approximately 2.65 times more likely to contract HIV than those who did not, even after accounting for other variables. These findings align with prior research suggesting that early initiation of sexual activity may increase vulnerability to HIV infection due to factors such as biological susceptibility and risky behaviors like low condom use and multiple sexual partners. The implications of these findings for HIV prevention strategies are substantial, suggesting that interventions aimed at delaying sexual debut could be an effective component in reducing HIV risk for this population. Targeted sex education programs that address the risks of early sexual debut may play a pivotal role in these prevention efforts. By employing a comprehensive approach, there is a possibility to advance efforts towards ending AIDS by 2030.

An Evaluation of TransLife Care: A Locally Developed Structural HIV Prevention Intervention for Transgender Women in Chicago, Illinois.

Transgender women are disproportionately impacted by HIV infection. We report herein the findings of a pre-post evaluation of the TransLife Care (TLC) project in Chicago, Illinois, on behaviors associated with HIV transmission among transgender women. Participants who received any TLC component versus those who did not were compared using mixed-effects logistic regression with random intercepts across follow-up time points. Ninety-seven participants aged 18 to 59 (median age 24) enrolled; 76.3% were transgender women of color. There was a decrease in condomless sex without consistent PrEP use at 8 months, which was not significantly different between those who did and did not receive the TLC intervention, controlling for calendar time. Evidence does not indicate that the TLC reduces condomless sex without PrEP protection among urban transgender women. However, given the preponderance of evidence of the influence of structural barriers on condomless sex, future research should continue to test the efficacy of structural interventions.

Risky sexual behavior and associated factors among university students in Ethiopia: a cross-sectional national survey.

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.

A 3D-printed condom intrauterine balloon tamponade: Design, prototyping, and technical validation.

Post-partum haemorrhage is among the main causes of (preventable) mortality for women in low-resource settings (LRSs), where, in 2017, the mortality ratio was 462 out of every 100 000 live births, over 10 times higher than for high-resource settings. There are different treatments available for post-partum haemorrhage. The intrauterine balloon tamponade is a medical device that proved to be a simple and cost-effective approach. Currently, there are several balloon tamponades available, with different design and working principles. However, all these devices were designed for high-resource settings, presenting several aspects that could be inappropriate for many lower-income countries. This paper presents the results of a preclinical study aiming at informing the design, prototyping and validation of a 3D-printed intrauterine balloon tamponade concept, contributing towards the United Nation's Sustainable Development Goal 3: Good health and Well-being. Frugal engineering concepts and contextualised design techniques were applied throughout, to define the design requirements and specifications. The performance of the final prototype was validated against the requirements of the UK National Health System (NHS) technical guidelines and relevant literature, measuring the water leak and pressure drop over time, both open air and in a approximate uterus model. The resulting prototype is made up of six components, some of which are easy to retrieve, namely a water bottle, a silicone tube and an ordinary condom, while others can be manufactured locally using 3D printers, namely a modified bottle cap, a flow stopper and a valve for holding the condom in place. Validation testing bore promising results with no water or pressure leak open air, and minimal leaks in the approximate uterus model. This demonstrates that the 3D printed condom-based intrauterine balloon tamponade is performing well against the requirements and, when compared to the state of the art, it could be a more appropriate and more resilient solution to low-resource settings, as it bypasses the challenges in the supply of consumables and presents a greener option based on circular economy.

Differences in condom access and use and associated factors between persons with and without disabilities receiving social cash transfers in Luapula province, Zambia-A cross-sectional study.

Persons with disabilities are disadvantaged in accessing sexual and reproductive health services, including condoms. In this study, we investigated whether condom access and use and their associated factors differed between persons with and without disabilities. We used data from adults in households receiving the Government of Zambia social cash transfers (SCT) in four districts of Luapula province. Condom access and use was the outcome. Disability, defined by the Washington Group Short Set Questions on Disability, was the main predictor. We performed logistic regression analyses to determine the associations between condom access and use and disability. In multivariable analyses, we controlled for covariates including age, sex, marital status, poverty status, HIV testing, and receiving the SCT. The sample comprised 1,143 people aged 16-49, with a median age of 21 years (interquartile range 18-28); 57.4% (n = 656) were female, 86.5% (n = 989) accessed and used condoms, and 17.9% (n = 205) were disabled, rating themselves with a 3 or a 4 on a scale of 1 = "not limited" to 4 = "cannot at all" in performing any of the six daily functions (seeing, hearing, walking, cognition, self-care, or communicating). Nearly sixty percent(58.5% (n = 120)) of persons with disabilities were female, 79.5% (n = 163) reported being very poor, 87.8% (n = 180) reported receiving SCT, and 86.3% (n = 177) reported accessing and using condoms. Condom access and use did not differ between persons with and without disabilities (adjusted odds ratio: 1.09; 95% confidence interval [CI]: 0.60-1.98]). We found no differences between persons with and without disabilities in condom access and use. We established that individual-level factors such as age, sex, marital status, and knowledge of being HIV positive might play a more important role in condom access and use than disability. Condom promotion interventions should account for these factors.

Condom use increased after a peer group intervention implemented by community volunteers in Malawi.

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.

Risk-stratified analysis of sex risk behaviors and correlates among school-going adolescents in Argentina: insights from a national survey.

OBJECTIVES: This study was conducted to address a critical gap in understanding adolescent sexual health risks in Argentina, a country that has undergone substantial socio-economic changes that made significant strides in education and healthcare. METHODS: A secondary data analysis of the 2018 Argentina Global School-based Student Health Survey was performed. In this study, 23,262 sexually active adolescents were categorized into four risk groups based on the predicted granular risk: number of sexual partners and condom use in their last sexual encounter. RESULTS: Males and older adolescents were more prone to high-risk sexual behaviors. Additionally, key psychosocial factors such as loneliness, anxiety, experiences of violence, and school absenteeism were significantly associated with high-risk sexual behaviors. Early alcohol use and recent experiences of hunger were also identified as strong predictors of heightened sexual risk behaviors. Conversely, positive parental engagement and awareness exhibited protective factors. CONCLUSIONS: These findings highlight the necessity for policy interventions that focus on mental health support, parental involvement, and awareness of adolescent issues and activities.

Determinants of Intention to Use HIV Pre-exposure Prophylaxis and Condom Use Among a Sample of Cisgender Female Sex Workers Working Mostly Outdoors in Madrid, Spain.

There is scant knowledge regarding pre-exposure prophylaxis (PrEP) use among female sex workers (FSWs) in Europe. Spain recognized FSWs as a population at high risk of acquiring HIV and granted them subsidized access to PrEP when the medication first became nationally available in 2019. Nevertheless, FSWs represented just 0.2% of PrEP users in 2022. A total of 102 HIV-negative FSWs reached through field activities of local NGOs located in Madrid were interviewed between January and March 2022. Participants were selected through convenience sampling over a fixed recruitment period. FSWs completed a 73-item survey with questions about individual, occupational, social, and structural determinants. The objective of this study was to identify (1) the prevalence of intention to use oral PrEP and its determinants, and (2) the prevalence of inconsistent condom use, which is the risk factor that qualifies FSWs for subsidized PrEP in the national health system, and its determinants. Importantly, the study sample overrepresented street-based FSWs (71.6%). A quarter (25.5%) of the study participants used condoms inconsistently. PrEP awareness was low (9.8%), but intention to use PrEP was high (72.5%). Intention to use oral PrEP was significantly associated with feeling protected against HIV by taking PrEP and perceiving insufficient protection by condom use alone. Inconsistent condom use was significantly associated with frequent heroin/cocaine use, having clients who inject drugs, and willingness to take PrEP despite it not protecting 100% against HIV infection. FSWs, in this specific sample, are likely to benefit from targeted PrEP awareness campaigns and implementation projects that prioritize those who use drugs and are more likely to engage in condomless sex.

Development of a HIV Prevention Program to Promote Condom Use Among Iranian Female Sex Workers: Application of An Intervention Mapping Approach.

We used an Intervention Mapping Approach (IMA) to derive multi-level HIV prevention strategies aiming to develop an HIV prevention intervention program among female sex workers (FSWs). We also aimed at pilot testing the effects of the IMA-based "HIV Prevention and Awareness Program (HIV-PAP)" on safe sex behaviors and its determinants among FSWs in Tabriz, Iran. To develop HIV-PAP, we conducted the six-step process of IMA. At Step 1, in a cross-sectional study, 140 FSWs were face-to-face interviewed. At Step 2, the program matrix was provided based on the importance and variability for identifying priority factors. At Steps 3 and 4, the methods and strategies for behavioral change were selected, and the HIV-PAP program components and materials were developed. At Steps 5 and 6, evaluation (as a pilot testing with Static-Group Comparison design) was conducted applying a pre-experimental study, in which 30 FSWs were assigned to intervention (n = 15) and control (n = 15) groups. The intervention group participated in a two-month long program, and one month later, the initial questionnaires were completed by both groups. The respondents (M age: 33.4 years, SD: 9.7) acquired low score (less than 50%) in negotiating for condom use (49.8%) only, and moderate scores (50-65%) in perceived social support (61.6%) and knowledge (60.5%). Adjusted for other variables, the factors (R2 = 32.0%) associated with safe sex behaviors among FSWs were predisposing factors [self-efficacy (ß = 0.331), perceived norms (ß = 0.945), and perceived barriers (ß = 0.258)], condom use negotiation (ß = 1.386), and environmental factors (ß = 0.333). Our IM-based framework had an adequate fit index (χ2 = 130.8, CFI = 0.78). Looking for inter-group comparison after intervention, we found significant mean difference (MD) for knowledge (MD: 2.18; 95% Confidence Interval (CI) - .38 to 4.74, p < 0.05), self-efficacy to use condom (MD: 6.71; 95% CI - 1.85 to 9.29, p < 0.05), perceived risk (MD: 2.03; 95% CI 0.58, to 3.49, p < 0.05), perceived social support (MD: 4.64; 95% CI - 5.37 to 11.31, p < 0.01), and safe sexual behaviors (MD: 7.75; 95% CI - 4.19 to 9.71, p < 0.05). The HIV-PAP showed effectiveness in promoting safe sexual behaviors and their determinants among FSWs. Healthcare providers should better understand the determinants of safe sexual behaviors among FSWs in the settings with legal prohibitions for sex work. In such communities, they should try to either develop or adapt such stage-specific interventions, within which promoting the above-mentioned factors is the core priorities of the program.

Trends in different contraception methods among women attending the Melbourne Sexual Health Centre from 2011 to 2020.

OBJECTIVES: The efficacy and availability of contraception have changed in the last several decades; however, unintended pregnancies continue to be an issue in Australia. This study aimed to describe trends in contraception in women attending a sexual health service over 9 years. STUDY DESIGN: Repeated cross-sectional study. METHODS: Women aged 16-49 years attending Melbourne Sexual Health Centre between 2011 and 2020 were included. Women were asked what methods of contraception they currently use. Contraception were categorised into long-acting reversible contraception (LARC; e.g. intrauterine devices and implants classified as highly effective), moderately effective contraception (e.g. oral contraception pill), less effective contraception (e.g. condom and withdrawal) and no contraception, as defined by US Centers for Disease Control and Prevention guidelines. Multivariable logistic regression was used to examine the factors associated with the use of moderate-high-efficacy contraception. RESULTS: A total of 38,288 women were included with a median age of 25 (interquartile range: 22-29). Between 2011 and 2020, there was a decreasing trend in condom (63.3%-56.1%; Ptrend <0.001) and oral contraception (27.2%-20.5%; Ptrend <0.001) use, whilst there was an increasing trend in the use of LARCs: implant (4.6%-6.0%; Ptrend = 0.002) and intrauterine device (2.8%-11.8%; Ptrend <0.001). Increasing age was associated with decreased odds of using moderate-high-efficacy contraception (Ptrend <0.001). Compared with Oceanian-born women, Asian (adjusted odds ratios [aOR] = 0.63, 95% confidence interval [CI]: 0.56-0.72) and Middle Eastern-born women (aOR = 0.60, 95% CI: 0.48-0.74) had lower odds of using moderate-high-efficacy contraception, whilst European (aOR = 1.23, 95% CI:1.07-1.41) and North American-born women (aOR = 1.51, 95% CI: 1.22-1.87) had higher odds of using moderate-high-efficacy contraception. CONCLUSIONS: Between 2011 and 2020, LARC use has increased, whilst less effective contraceptives, such as condom and oral contraception, have decreased among women at Melbourne Sexual Health Centre. Further research is required to understand age and ethnic disparities in contraception methods for future family planning programmes.

The Best Predictor of Future Behavior May Be the Past: Exploring Behavior Change in Men Who Have Sex with Men Using Pre-exposure Prophylaxis in the Netherlands.

Pre-exposure prophylaxis (PrEP) use prevents HIV transmission, and may lead to changes in sexual behavior. We aimed to explore sexual behavior over time, and identify predictors of behavior change in men who have sex with men (MSM) using PrEP at sexual health centers (SHC) in the Netherlands. We used longitudinal data from the national STI surveillance database (January 2018-June 2021) of HIV-negative MSM who first initiated PrEP in the national PrEP pilot. We modelled behavior change after PrEP initiation, and identified predictors of behavior change using multi-state Markov models. The probability of stopping group sex, chemsex, use of poppers or erection stimulants, and having ≥ 10 partners in the past 6 months among included MSM (n = 4,349, n SHC visits = 21,820) was higher compared to the probability of starting with these behaviors after PrEP initiation. However, MSM who used condoms consistently during anal sex had a high probability of changing to inconsistent condom use (0.8) at the next visit, and inconsistent condom users mostly remained inconsistent (0.8). First visit, visiting the SHC more often (vs. regular), and STI diagnosis were predictors of starting or continuing with most of the behaviors associated with increased risk. Behavior change was less likely among older participants (> 34 compared to ≤ 34 years), and during COVID-19 lockdown and post-lockdown periods compared to pre-COVID-19. Although condom use decreased over time, transitions towards stopping with other behaviors associated with increased likelihood of acquiring an STI after PrEP initiation were common. This may suggest increased sexual empowerment, especially among younger MSM. Predictors of behavior change may help to identify MSM who are likely to start with or continue to engage in these behaviors in the near future and to provide suitable and timely counselling about behavior and PrEP adherence.

Adolescents' pornography viewing frequency and its relationship with condom attitudes.

Background This study examined adolescent pornography viewing and its' relationship with condom attitudes. Methods Data were from 457 adolescents aged 13-18years old who completed an online survey assessing pornography viewing frequency and condom attitudes. Results Many adolescents in our sample had viewed pornography in the past year (n =188, 41%), with pornography viewing frequency being higher among older adolescents (P =0.02), those who have had sex in the past year (P =0.001), and those who identified as White (P =0.01), LGB+ (P =0.05), and male (P =0.001). Adolescents who viewed pornography more frequently had more negative condom attitudes (r =-0.18, P Conclusions A substantial proportion of adolescents in our sample viewed pornography and those who view more frequently had more negative condom attitudes. Results indicate a need for experimental studies examining this relationship and interventions addressing pornography literacy among adolescents.
