RESUMO

OBJECTIVES: International travel combined with sex may contribute to dissemination of antimicrobial-resistant (AMR) Neisseria gonorrhoeae (Ng). To assess the role of travel in Ng strain susceptibility, we compared minimum inhibitory concentrations (MICs) for five antibiotics (ie, azithromycin, ceftriaxone, cefotaxime, cefixime and ciprofloxacin) in strains from clients with an exclusively Dutch sexual network and clients with an additional international sexual network. METHODS: From 2013 to 2019, we recorded recent residence of sexual partners of clients (and of their partners) with Ng at the Center for Sexual Health of Amsterdam. We categorised clients as having: (1) exclusively sexual partners residing in the Netherlands ('Dutch only') or (2) at least one partner residing outside the Netherlands. We categorised the country of residence of sexual partners by World Bank/EuroVoc regions. We analysed the difference of log-transformed MIC of Ng strains between categories using linear or hurdle regression for each antibiotic. RESULTS: We included 3367 gay and bisexual men who had sex with men (GBMSM), 516 women and 525 men who exclusively had sex with women (MSW) with Ng. Compared with GBMSM with a 'Dutch only' network, GBMSM with: (1) a Western European network had higher MICs for ceftriaxone (ß=0.19, 95% CI=0.08 to 0.29), cefotaxime (ß=0.19, 95% CI=0.08 to 0.31) and cefixime (ß=0.06, 95% CI=0.001 to 0.11); (2) a Southern European network had a higher MIC for cefixime (ß=0.10, 95% CI=0.02 to 0.17); and (3) a sub-Saharan African network had a lower MIC for ciprofloxacin (ß=-1.79, 95% CI=-2.84 to -0.74). In women and MSW, higher MICs were found for ceftriaxone in clients with a Latin American and Caribbean network (ß=0.26, 95% CI=0.02 to 0.51). CONCLUSIONS: For three cephalosporin antibiotics, we found Ng strains with slightly higher MICs in clients with partner(s) from Europe or Latin America and the Caribbean. International travel might contribute to the spread of Ng with lower susceptibility. More understanding of the emergence of AMR Ng is needed.

RESUMO

BACKGROUND: Daily oral pre-exposure prophylaxis (PrEP) is an effective HIV prevention option for those who are most vulnerable to HIV infection, especially young women (YW). Objection by or lack of support from male sexual partners has been shown to impact YW's ability to take PrEP consistently. We explored the views of YW, and male partners and male peers of YW in Siaya County, Western Kenya, to illustrate how men influence, and can support, YW in using PrEP. METHODS: We used Photovoice to capture the views of YW ages 18-24 who were currently or previously enrolled in the DREAMS program and with current or previous experience taking PrEP. We also captured the views of YW's sexual partners and male peers. The YW completed eight photo assignments that focused on identifying factors influencing their PrEP use, and male participants completed four photo assignments focused on identifying ways men support or hinder YW's PrEP use. Photographs were presented and discussed in same- and mixed-gender groups using the SHOWeD method. YW also participated in in-depth interviews. The analysis focused on identifying themes that described men's influence on YW's PrEP adherence and persistence. RESULTS: Among YW, a restricting male influence on PrEP use emerged in the majority of photo assignments such that YW's photographs and discussions revealed that men were more often viewed as barriers than supporters. YW perceived that they had little autonomy over their sexual lives and choice to use PrEP. YW's PrEP use was perceived to be hindered by stigmatizing community narratives that influenced men's support of PrEP use among women. Male participants suggested that men would support YW's PrEP use if PrEP was better promoted in the community and if men were more knowledgeable about its benefits. CONCLUSIONS: A lack of support from male partners and peers and stigmatizing community narratives influence YW's PrEP use. Community-based programs should include education about PrEP specifically for male partners and peers of YW to positively influence PrEP use among YW.

RESUMO

BACKGROUND: Sexual violence remains a persistent and devastating issue in eastern Democratic Republic of Congo (DRC). AIM: To elucidate the sociodemographic, sexual, and obstetrical characteristics associated with the experiences of victims of sexual violence (VSV) among women in the region. MATERIALS AND METHODS: A cross-sectional study was conducted involving 625 women from eastern DRC. Participants provided self-reported data, collected through interviews conducted by trained female interviewers in secure environments. Associations between VSV and various sociodemographic and reproductive health factors were examined. RESULTS: Of the respondents, 26.1% reported experiences of sexual violence. VSV were predominantly younger, with 56.44% aged between 15 and 24 years. Single women comprised 57.67% of VSV, and 37.42% identified as farmers. There were 33.13% of VSV who were illiterate, and 81.60% belonged to the low socio-economic stratum. Early physiological and reproductive milestones characterised VSV: 52.15% experienced menarche at or before 13 years, 34.97% initiated sexual intercourse before age 15, and 18.70% reported their first pregnancy before age 15. Higher nulliparity was observed in VSV (29.45%) compared to non-VSV (9.31%). A lower prevalence of HIV infection was found among VSV (11.04%) relative to non-VSV (25.76%). CONCLUSION: Sexual violence in the eastern DRC exhibits multifactorial associations. Younger women, those in certain occupations, and those with specific reproductive histories appear more vulnerable. The findings underscore the urgency for targeted interventions, enhanced access to education, and improved reproductive health services. Addressing these pressing issues should remain a primary focus in both societal and public health spheres.

RESUMO

Objective: In this study, we aimed to investigate whether age first had sexual intercourse (AFSI) and lifetime number of sexual partners (LNSP) have a direct causal effect on cervical cancer by Mendelian randomization (MR) analysis. Methods: Four approaches were used for MR Analysis, including MR-Egger, weighted method, weighted median, and inverse variance weighted (IVW). MR Pleiotropy RESidual Sum and Outlier (MR-PRESSO) as well as MR-Egger regression analysis were conducted to detect whether there was pleiotropy between IVs and outcome, and the outlier SNPs can be detected by MR-PRESSO. The presence or absence of heterogeneity among IVs was suggested according to Cochran's Q statistic. Leave-one-out sensitivity analysis was performed to identify and remove SNPs which could independently change the results. We corrected the results using Bonferroni correction. Results: From the results of IVW, AFSI had a negative effect on cervical cancer (OR = 0.996, 95 % CI: 0.995, 0.998 P = 1.70E-07), which still persisted after Bonferroni correction. However, no causal effect of LNSP on cervical cancer was found according to the IVW results (OR = 1.003, 95 % CI: 1.000, 1.007, P = 0.071). From the results of MR-PRESSO and MR-Egger, no SNP with horizontal pleiotropy between cervical cancer was detected and no SNP was identified as an outlier SNP. Cochran's Q statistic suggested that no heterogeneity existed among IVs of AFSI and LNSP. According to Leave-one-out analysis, the results of MR did not change after excluding any single IV. Conclusion: This MR study reveals that early AFSI has a causal effect on cervical cancer.

RESUMO

Prior research has quantitatively examined why heterosexual men and women report different numbers of lifetime different-sex sexual partners, whereas qualitative work has analyzed how men's masculinity-and to a lesser extent, women's femininity-is tied to gender norms about sexual activity. Less research, however, has quantitatively examined the associations between self-rated masculinity and femininity and reported number of lifetime sexual partners. This brief report uses a large sample of Canadians (n = 2117) to examine how self-rated masculinity and femininity relate to reported numbers of sexual partners among four groups of cisgender people: (1) heterosexual men (n = 972), (2) heterosexual women (n = 979), (3) gay and bisexual/pansexual men (n = 99), and (4) lesbian and bisexual/pansexual women (n = 67). Results demonstrate that self-rated femininity was negatively, and masculinity positively, associated with reported numbers of lifetime different-sex sexual partners among heterosexual women. No significant associations emerged for other groups. The lack of significant associations among heterosexual men may be attributable to the fact that most rated themselves as very masculine and not very feminine, whereas there was more variation among heterosexual women. In contrast, the non-significance among LGBQ women and men could reflect that subcultural norms and practices more strongly shape the number of sexual partners individuals report having in these communities. These results demonstrate that it would be beneficial for researchers to measure self-rated masculinity and femininity in future studies about sexual partnering practices, especially among heterosexual cisgender women.

RESUMO

HIV is recognised as a multifaceted chronic disease, bearing psychosocial consequences that potentially impact on the personal and social well-being of those living with it. Adolescents and youth bear a significant proportion of the burden of the HIV epidemic but they have low rates of disclosure of their HIV status. This study aims to determine the views of adolescents living with perinatally acquired HIV on HIV status disclosure among 361 adolescents aged 15-19 in Eswatini. A cross-sectional study was conducted on adolescents who already knew their status, and data were collected using a structured questionnaire. A majority of the participants, 55% (n = 200), were females, and 44% (n = 160) were males. A low number of adolescents (22%) had disclosed their HIV status to anyone. Adolescents who found it difficult to understand disclosure themselves had low levels of onward disclosure (27%) compared to adolescents who better understood the disclosure event. Our results revealed that adolescents' prevalence of HIV status disclosure was low. This raises concerns as some of the adolescents were in relationships with partners who were not aware of their status. However, older adolescents displayed some level of disclosure self-efficacy in that a higher proportion of them disclosed better than younger adolescents.

RESUMO

Background: Limited studies have explored the association between sexual factors [age at first sexual intercourse (AFS) and lifetime number of sexual partners (LNSP)] and cardiovascular diseases (CVDs), leaving the causality inconclusive. Methods: We performed a bi-directional Mendelian randomization (MR) study to investigate the causality between sexual factors and CVDs, including coronary artery disease, myocardial infarction, atrial fibrillation (AF), heart failure (HF), and ischemic stroke (IS). Single-nucleotide polymorphisms (SNPs) for sexual factors were extracted from the UK Biobank. Statistics for each CVD were derived from two different databases. MR estimates were calculated per outcome database and were combined through meta-analysis. Several complementary sensitivity analyses were also performed. Results: The primary analysis suggested that AFS was causally associated with the risk of CVDs; the odds ratios (ORs) ranged from 0.686 [95% confidence interval (CI), 0.611-0.770] for HF to 0.798 (95% CI, 0.719-0.886) for AF. However, the association between AFS and IS (OR, 0.844; 95% CI, 0.632-1.126) was not consistent in the meta-analysis after excluding SNPs related to confounders. Moreover, non-significant associations were found between LNSP and CVDs. Reverse direction MR analysis showed that CVDs were not associated with sexual factors. Conclusions: Genetic evidence suggested that AFS was causally associated with the risk of CVDs except for IS, whereas non-significant association of LNSP with CVDs was detected. Further investigation into AFS could be warranted in preventing the progression of CVDs.

RESUMO

Access to antiretroviral therapy (ART) has promoted a significant decrease in mortality of vertically HIV-infected children. As a result, there has been an increasing growth of this population that reaches adolescence. These adolescents face problems such as self-disclosure and the stigma of the disease. This study aimed to determine the process followed by perinatally HIV-infected adolescents in self-disclosing their HIV status to significant others and the barriers and promoters of perinatally HIV-infected adolescents' disclosure of their HIV status to others. Data were collected from 15-19-year-old adolescents through 23 in-depth individual interviews and three focus groups. For adolescents, a clear barrier to disclosure was being told when they were younger by a parent to keep their status secret from other people. Lack of trust and fear of breaches of confidentiality which would lead to stigma and discrimination also hindered disclosure. For those adolescents who disclosed, they did so face to face and through short text messages. Adolescents expressed the need to be capacitated to self-disclose and also called for HIV and AIDS education to the general public as a way of fighting stigma and discrimination in their communities and in society. For adolescents to be able to disclose, they have to work through issues of acceptance of their own HIV status first. This study is the first-ever study to document difficulties faced by adolescents in the self-disclosure of their status in Eswatini.

RESUMO

Purpose: This study aimed to explore the sexual behaviors and intimate relationships of sexual partners of young patients with cervical cancer. Patients and Methods: This study employed a descriptive phenomenological research design, which falls within the realm of qualitative research methods. Qualitative research typically utilizes interview techniques for gathering participants' experiences, perceptions, and behaviors. This study conduct face-to-face semi-structured interviews with the sexual partners of 15 young cervical cancer patients receiving cancer treatment to collect their experiences and perspectives on intimate relationships and sexual behavior with cervical cancer patients, and use the Colaizzi method for data analysis. Results: Four themes were identified through the interview analysis: (1) reduction or absence of sexual behavior, (2) unpleasant sexual experiences, (3) adjustment of intimate relationships, and (4) lack of sexual health education. Conclusion: The sexual partners of young cervical cancer patients have experienced significant shifts in their perspectives on sexual behavior and intimate relationships. These changes include reduction or absence of sexual behavior, unpleasant sexual experiences, adjustment of intimate relationships, and lack of sexual health education. Hospitals should pay more attention to the sexual behavior and intimate relationships of patients with cervical cancer and their sexual partners, and social support systems and psychological and emotional counselling services should be established for providing relevant knowledge and guidance.

RESUMO

Introduction: Syphilis is a highly transmissible sexually transmitted infection. Rising rates of infection and reinfection are of great concern to public health officials. In local health departments across the U.S., disease intervention specialists attempt to interview all people diagnosed with early syphilis, to elicit sexual partner information, and to trace and treat the partners. This method of interviewing and contact tracing is an evidence-based practice that reduces the spread of the disease in the community, but few studies address the relationship between the disease intervention specialists' interviews and index patient reinfections. We hypothesized that patients who were interviewed, patients who provided partner information, and patients with more treated partners would have a reduced risk of reinfection. Methods: Our sample consisted of 82 men listed in the Suffolk County Department of Health Services syphilis log who were diagnosed with primary, secondary, or early latent syphilis. We determined whether and when the patients were reinfected during a set time period, from 2016 to 2020. Kaplan-Meier analyses with log-rank statistics and Cox hazard proportional models were used to calculate time to reinfection and hazard ratios. Results: Although none of the models produced p<0.05, notable trends were observed. In subset analyses of interviewed patients, 23.8% of patients who named partners were reinfected during the study period, whereas 50% of those who did not name partners were reinfected during that time. In addition, the hazard ratio for index patients who named partners was 0.51 (95% CI=0.225, 1.170, p=0.113). When some or all the patients' partners were treated, 20% were reinfected by the end of the study, whereas 33.3% of cases with no partners treated were reinfected by the end of the study. The hazard ratio for patients with some or all partners treated was 0.48 (95% CI=0.136, 1.711, p=0.258). Conclusions: Although none of the results was statistically significant, trends suggest that partner elicitation and partner treatment status could be associated with reduced risk of syphilis reinfection. Because this pilot study utilized a small convenience sample that was not tested for statistical power, we could not adequately address these trends. Future studies, with larger sample sizes, should address these relationships.

RESUMO

In Kenya similar to other countries in Eastern and Southern Africa There is a disproportionately high burden of the global HIV incidence among youth ages 15-24 years, and where adolescent girls and young women account for up to a third of all incident HIV infections and more than double the burden of HIV compared to their male peers. Previous work has shown early sexual debut as entry point into risks to sexual and reproductive health among young people including STI/HIV acquisition. This was a formative assessment of the local context of three sexual risk behaviors among youth ages of 15-24 years: early sexual debut, multiple sexual partnerships, and age-mixing /intergenerational sex for purposes of informing comprehensive combination HIV intervention program design. We conducted a cross-sectional formative qualitative study in four sub-counties within Homabay county a high HIV prevalence region of Kenya. Participants were recruited through youth groups, schools, government offices and, community gatekeepers using approved fliers, referred to a designated venue for focus group discussion (FGD). After oral informed consent, twelve FGDs of 8-10 participants were carried out. Transcripts and field notes were uploaded to Atlas.ti qualitative data analysis and research software (version 8.0, 2017, ATLAS.ti GmbH). Open coding followed by grouping, categorization of code groups, and thematic abstraction was used to draw meaning for the data. A total of 111 youth participated in the FGD, 65 males and 46 females. The main findings were that youth engaged in early sex for fear of being labeled 'odd' by their peers, belief (among both male and female) that 'practice makes perfect', curiosity about sex, media influence, need to prove if one can father a child (among male), the notion that sex equals love with some of the youth using this excuse to coerce their partners into premature sex, and the belief that sex is a human right and parents/guardians should not intervene. Male youth experienced more peer-pressure to have sex earlier. Female youths cited many reasons to delay coitarche that included fear of pregnancy, burden of taking care of a baby, and religious doctrines. Having multiple sexual partners and intergenerational sexual relationships were common among the youth driven by perceived financial gain and increased sexual prowess. HIV prevention strategies need to address gender vulnerabilities, as well as promoting a protective environment, hence application of combination prevention methods is a viable solution to the HIV pandemic.Trial registration number: The study was approved by the KNH/UoN Ethics review committee (KNH/UoN ERC-P73/03/2011) and New York University (NYU Reg no.-00000310).

RESUMO

Background: Two required inputs to mathematical models of sexually transmitted infections are the average duration in epidemiological risk states (e.g., selling sex) and the average rates of sexual partnership change. These variables are often only available as aggregate estimates from published cross-sectional studies, and may be subject to distributional, sampling, censoring, and measurement biases. Methods: We explore adjustments for these biases using aggregate estimates of duration in sex work and numbers of reported sexual partners from a published 2011 survey of female sex worker in Eswatini. We develop adjustments from first principles, and construct Bayesian hierarchical models to reflect our mechanistic assumptions about the bias-generating processes. Results: We show that different mechanisms of bias for duration in sex work may "cancel out" by acting in opposite directions, but that failure to consider some mechanisms could over- or underestimate duration in sex work by factors approaching 2. We also show that conventional interpretations of sexual partner numbers are biased due to implicit assumptions about partnership duration, but that unbiased estimators of partnership change rate can be defined that explicitly incorporate a given partnership duration. We highlight how the unbiased estimator is most important when the survey recall period and partnership duration are similar in length. Conclusions: While we explore these bias adjustments using a particular dataset, and in the context of deriving inputs for mathematical modelling, we expect that our approach and insights would be applicable to other datasets and motivations for quantifying sexual behaviour data.

RESUMO

BACKGROUND: Sexually transmitted infections (STIs) and food insecurity are public health concerns in the United States (US) due to their growing prevalence and incidence among young people, and particularly in college students. Studies have reported that college students are at higher risk of STIs due to the high rates of risky sexual behavior (RSB). Most studies report a food insecurity prevalence of more than 30% among college students, which was more than twice the overall national food insecurity rate of 10.5% in 2020. This study aims to assess the relationship between food insecurity and RSB among college students during the early-stages of the COVID-19 pandemic. METHODS: This was a cross-sectional study from a convenience sample of 320 students enrolled at the University of Nevada, Las Vegas during the 2020 Fall semester. Data was collected using an online survey. Univariate and multivariate logistic regression analyses were conducted. RESULTS: Food insecure students were 2.9 times more likely to report receiving or giving fellatio without using a condom at least once in the past 6 months (P < 0.01) compared to food secure students. There was no significant association between food insecurity and other RSBs evaluated in this study. CONCLUSIONS: The current study provides valuable information on food insecurity and RSB among college students during the early stages of the COVID-19 pandemic. Larger and longitudinal studies are needed to assess the trajectory of the association between food insecurity and fellatio with no condom use and other RSB among college students.

RESUMO

Early-phase HIV remission ("cure") trials aim to test interventions developed to eradicate HIV or to sustainably control HIV without antiretroviral treatment (ART). Many remission trials include analytic treatment interruption (ATI) to evaluate interventions, which increases the risk to participants and their sexual partners. We conducted an online questionnaire of international HIV remission trial investigators and other study team members to assess their expectations regarding the time to achieve long-term control of HIV replication without treatment (functional cure) or complete eradication of replication-competent HIV virus (sterilizing cure); attitudes toward HIV remission research and the feasibility, acceptability, and efficacy of six HIV transmission risk mitigation strategies during trials with ATI of fixed duration. Nearly half of respondents (47%) reported expecting a functional cure for HIV to be achieved in 5-10 years, and one-third (35%) reported 10-20 years for a sterilizing cure to be achieved. On a scale of -3 to 3, mean scores indicated greater respondent concern about the risk of HIV transmission to partners during ATI (Time to rebound Mean: 0.4 and Fixed duration Mean: 11), compared to participant health risks from ATI (Time to Rebound Mean: -.9 and Fixed duration Mean: 0.0). With regard to feasibility, acceptability, and efficacy respectively, mitigation efforts rated positively included: requiring counseling for potential participants (Means: 2.3; 2.1; and 1.1), providing partner referrals for PrEP (Means: 1.3; 1.3; 1.5), providing pre-exposure proxylaxis directly to partners (Means: 1.0; 1.5; 1.6), and monitoring participants for new sexually transmitted disease acquisition (Means: 1.9; 1.4; 1.0). Respondents were less positive about requiring that participants' sexual partner(s) participate in risk counseling or limiting participation to those who commit to abstaining from sex during the entire ATI period. Our study demonstrates that HIV remission trial investigators and study team members are concerned about the risk of transmission to sexual partners during ATI. Separating the assessment of risk mitigation strategies for transmission risk into feasibility, acceptability, and efficacy allows the discovery of strategies that may best achieve all three outcomes. Additional research is needed to compare these more fine-grained assessments with views held by other investigators, people living with HIV, and trial participants.

RESUMO

INTRODUCTION: Despite widespread success in reducing vertical HIV transmission, most antenatal care (ANC) programmes in eastern and southern Africa have not emphasized primary prevention of maternal HIV acquisition during pregnancy and lactation/breastfeeding. We hypothesized that combination HIV prevention interventions initiated alongside ANC could substantially reduce maternal HIV incidence. METHODS: We constructed a multi-state model describing male-to-female HIV transmission in steady heterosexual partnerships during pregnancy and lactation/breastfeeding, with initial conditions based on population distribution estimates for Malawi and Zambia in 2020. We modelled individual and joint increases in three HIV prevention strategies at or soon after ANC initiation: (1) HIV testing of male partners, resulting in HIV diagnosis and less condomless sex among those with previously undiagnosed HIV; (2) initiation (or re-initiation) of suppressive antiretroviral therapy (ART) for male partners with diagnosed but unsuppressed HIV; and (3) adherent pre-exposure prophylaxis (PrEP) for HIV-negative female ANC patients with HIV-diagnosed or unknown-status male partners. We estimated the percentage of within-couple, male-to-female HIV transmissions that could be averted during pregnancy and lactation/breastfeeding with these strategies, relative to base-case conditions in which 45% of undiagnosed male partners become newly HIV diagnosed via testing, 75% of male partners with diagnosed but unsuppressed HIV initiate/re-initiate ART and 0% of female ANC patients start PrEP. RESULTS: Increasing uptake of any single strategy by 20 percentage points above base-case levels averted 10%-11% of maternal HIV acquisitions during pregnancy and lactation/breastfeeding in the model. Joint uptake increases of 20 percentage points in two interventions averted an estimated 19%-23% of transmissions, and with a 20-percentage-point increase in uptake of all three interventions, 29% were averted. Strategies achieving 95% male testing, 90% male ART initiation/re-initiation and 40% female PrEP use reduced incident infections by 45%. CONCLUSIONS: Combination HIV prevention strategies provided alongside ANC and sustained through the post-partum period could substantially reduce maternal HIV incidence during pregnancy and lactation/breastfeeding in eastern and southern Africa.

RESUMO

BACKGROUND: Risky sexual behaviors remain significant public health challenges among adolescents. Nearly 90% of adolescents live in low and middle-income countries (LMICs), but few studies have used standardized methodology to monitor the prevalence and trends of sexual behaviors among adolescents in LMICs. OBJECTIVE: This study aimed to assess the prevalence of sexual behaviors (ever had sexual intercourse, multiple sexual partners, and condom use) among adolescents aged 12 years to 15 years as well as the trends in prevalence between 2003 and 2017. METHODS: For this population-based study, we used recent data from the Global School-based Student Health Survey conducted in 69 LMICs from 2003 to 2017 to assess the recent prevalence of sexual behaviors by using complex analysis and a random effects meta-analyses method. Using the chi-square trend test, we also assessed the trends in the prevalence of sexual behaviors in 17 countries that had conducted ≥1 round of surveys from 2003 to 2017. RESULTS: We included 145,277 adolescents aged 12 years to 15 years (64,719/145,277, 44.5% boys) from the 69 LMICs that had conducted ≥1 survey and 80,646 adolescents aged 12 years to 15 years (34,725/80,646, 43.1% boys) from the 17 LMICs that had conducted ≥1 round of surveys. The recent global prevalence of ever had sexual intercourse was 6.9% (95% CI 6.2%-7.6%) and was higher among boys (10.0%, 95% CI 9.1%-11.1%) than girls (4.2%, 95% CI 3.7%-4.7%) and among those aged 14 years to 15 years (8.5%, 95% CI 7.7%-9.3%) than those aged 12 years to 13 years (4%, 95% CI 3.4%-4.7%). Among adolescents who had ever had sex, the recent global prevalence of having multiple sexual partners was 52% (95% CI 50.4%-53.6%) and was higher among boys (58%, 95% CI 56.1%-59.9%) than girls (41.4%, 95% CI 38.9%-43.9%) and among those aged 14 years to 15 years (53.5%, 95% CI 51.6%-55.4%) than those aged 12 years to 13 years (49.7%, 95% CI 45.9%-53.5%). Among adolescents who had ever had sex, the recent global prevalence of condom use was 58.1% (95% CI 56.2%-59.9%) and was higher among girls (59.2%, 95% CI 56.4%-61.9%) than boys (57.7%, 95% CI 55.7%-59.7%) and among those aged 14 years to 15 years (59.9%, 95% CI 58.0%-61.8%) than those aged 12 years to 13 years (51.6%, 95% CI 47.5%-55.7%). Between the earliest and latest surveys, the overall prevalence of ever had sexual intercourse (3.1% decrease) and condom use (2.0% decrease) showed downward trends. The overall prevalence of having multiple sexual partners increased by 2.6%. CONCLUSIONS: We provide evidence and important implication for policymakers to develop targeted policy support systems to prevent and reduce risky sexual behaviors among young adolescents in LMICs with a high prevalence of risky sexual behaviors.

RESUMO

Background and Aims: Female head-porters are a cohort of women who have migrated from their rural communities into commercial cities in search of better economic opportunities. These young women are vulnerable to untoward reproductive experiences. The study assesses the reproductive experiences of women and the factors influencing contraceptive use among them. Methods: A cross-sectional study was conducted from January to May 2021 in the Kumasi Metropolis (n = 280). The study included 280 female head-porters within the reproductive age of 15-49 years. Convenience sampling and consecutive recruitment were used to obtain the needed sample size. All statistical significance was declared at a p-value of <0.05. Results: Forty-two percent of respondents had a history of contraceptive use (all modern or artificial contraception). The study found gravidity (p < 0.0001), parity (p < 0.0001), number of sexual partners post-migration (p = 0.008), and age of first sex (p = 0.033) to be associated with contraceptive use among female head-porters. Conclusion: Fourteen percent had experienced sexual exploitation post-migration, the first sexual encounter of one-third of participants were nonconsensual, 19% had sex at or before 16 years, and 72% were aware of contraception. Reproductive experiences such as gravidity and sexual debut (age at first sex) have a significant influence on the use of contraception.

RESUMO

Introduction: HIV serostatus disclosure is a fundamental HIV prevention and care strategy yet with a paucity of literature. This study comprehended the factors associated with HIV serostatus disclosure to sexual partners among young people aged 15-24 years on anti-retroviral therapy (ART). Methods: This explanatory sequential study utilized quantitative data from 238 young people who had been on ART for over 12 months and were sexually active for at least 6 months in seven districts of Central Uganda. Pearson's Chi-square and multinomial logistic regression analysis at α=0.05 was used to determine the factors associated with serostatus disclosure among study participants. Qualitative data from 18 young people were collected using an in-depth interview guide and analyzed thematically. Results: Non-disclosure was at 26.9%, one-way disclosure was at 24.4%, and two-way disclosure was at 48.7%. Participants who contracted HIV from their partners were three times more likely (RRR=2.752; 95% CI: 1.100-6.888) to have one-way disclosure than non-disclosure, compared to those who had a perinatal infection. Those who contracted HIV from their partners were twice more likely (RRR=2.357; 95% CI: 1.065-5.214) to have two-way disclosure than non-disclosure, compared to those who had a perinatal infection. Participants who stayed with their partners were four times more likely (RRR=3.869; 95% CI: 1.146-13.060) to have two-way disclosure than non-disclosure, compared to those who stayed with their parents. Young people disclosed because they were tired of secrecy and desired treatment adherence and did not disclose due to fear of stigma and losing their partners' support. Conclusion: Many sexually active young people on ART did not disclose their HIV-positive status to sexual partners mainly due to poverty, having multiple-sexual partners, and stigma. Interventions fighting stigma, multiple-sexual relationships, and poverty among sexually active young people on ART should be strengthened.

RESUMO

Introduction: Childhood sexual abuse (CSA) is a hidden but serious public health issue that can lead to a series of behavioral consequences and health problems in adulthood. It has been well documented that transgender women (TGW) have a high prevalence of CSA victimization. Moreover, risky sexual behaviors are also widespread among TGW; nevertheless, research investigating the associations between CSA victimization and risky sexual behaviors in TGW represents a gap in the literature. Methods: Our research was carried out mainly in Shenyang of China from November 2018 to January 2019. Sociodemographic characteristics, as well as information on participants' HIV awareness and sexual behaviors, were collected through face-to-face interviews. The impact of CSA was examined through hierarchical logistic regression, adjusted for sociodemographic factors and HIV awareness. Results: In the sample of 247 adult TGW, 14.2% of them had a CSA history. In the previous 6 months, 30.8% of the participants reported condomless anal intercourse (CAI) and 38.5% of them had multiple sexual partners (MSP). The findings demonstrated that TGW with CSA history were more likely to take part in CAI (p = 0.001, OR = 4.252) or have MSP (p = 0.004, OR = 3.260) in adulthood. Furthermore, HIV knowledge was not a predictor of CAI or MSP, but higher HIV risk perception was associated with a greater probability of CAI. Conclusion: Transgender women with a history of CSA were more prone to engage in CAI and have MSP in China.

RESUMO

Partner engagement in antenatal care can improve care for pregnant people living with HIV. However, concerns about engaging unsupportive non-pregnant partners warrant further study to avoid engaging partners who pressure their pregnant partner to refuse testing or treatment and/or perpetuate intimate partner violence. We adapted established relationship functioning and partner behaviour questionnaires among pregnant people living with HIV initiating antenatal care in rural South Africa. We identified 13 previously validated psychometric scales with 255 items that assess relationship functioning and partner behaviour, but, to our knowledge, had not been used in Southern Africa. After item translation and cognitive interviewing with 30 pregnant people, we recruited an additional 208 pregnant people living with HIV receiving antenatal care. We conducted an exploratory factor analysis with maximum-likelihood extraction and oblique promax rotation with the 58 items and 10 scales that remained after translation and cognitive interviewing. We used parallel analysis, scree plots, and the Kaiser criterion to guide factor retention and assessed internal factor consistency via Cronbach's alpha. Of the 208 participants recruited, 197 (95%) answered each question and were included in the analysis. Exploratory factor analysis revealed 7 factors that assessed partner social support, sexual relationship power, emotional intimacy, threatened or enacted violence, sexual intimacy, violence in relationships, and partner engagement in pregnancy care via 37 items. Factor absolute Spearman correlations ranged from 0.012 to 0.518 and Cronbach's alpha ranged from 0.84 to 0.92. This preliminary analysis will guide further scale development. Future developments will also include relevant clinical outcomes to assess the predictive validity of the resulting measures. These steps will further refine these questions into a succinct screening tool to assess relationship functioning and partner behaviour. This screening tool may eventually guide the selection of partner-based interventions during pregnancy to improve outcomes for pregnant people and their partners.
