Behavioural strategies to reduce HIV transmission: how to make them work better

"What I Wish I Would've Known before My HIV Diagnosis": Qualitative Insights from Women Living with HIV to Inform HIV Prevention Strategies

In 2022, cisgender women accounted for one in five HIV diagnoses in the United States. Existing structural, social, and behavioral factors impede women's engagement with HIV prevention strategies including Pre-Exposure Prophylaxis (PrEP) access, condom usage, and uptake of HIV testing. This study explores the perspectives of women living with HIV (WLWH) about factors that may contribute to HIV acquisition and their advice for women who may benefit from HIV prevention strategies. We conducted semistructured interviews with 40 WLWH who were diagnosed on or after January 1, 2000. Interviews were conducted via Zoom and lasted 45-60 min. Interviews were professionally transcribed, coded, and analyzed to identify themes. Guided by the AIDS Risk Reduction Model, this study uses qualitative findings to describe the steps for recognizing and reducing HIV vulnerabilities. The analysis revealed three themes: (1) recognizing HIV risk for oneself and partner, (2) commiting to decreasing HIV risk, and (3) enacting HIV risk reduction strategies. After recognizing the personal and partner characteristics associated with increased HIV risk and committing to reducing that risk through self-love, relationship assertiveness, and boundary setting, women will be better prepared to enact risk reduction strategies. The four most commonly discussed strategies by WLWH included HIV testing, condom usage, PrEP, and avoiding drug use. This study highlights the importance of understanding the experiences of WLWH to inform effective HIV prevention strategies. Insights from these women emphasized the need for increased awareness, empowerment, and accessible resources to support HIV risk recognition and reduction among women.

Combination HIV Prevention Strategies in the Lisbon Cohort of Men who Have Sex with Men: A Longitudinal Cluster Analysis of Data from 2014 to 2021

This study aims to examine how HIV prevention tools were used and how they clustered together among men who have sex with men (MSM) testing at a community-based sexual health center in Lisbon, Portugal, from 2014 to 2021. We used data from 16,780 visits from adult cisgender MSM and had an HIV-negative test result at baseline in the Lisbon Cohort of MSM-an open, prospective cohort study conducted at CheckpointLX, a community-based sexual health center tailored to MSM, from 2014 to 2021. A longitudinal clustering approach was used to identify clusters of HIV prevention (cluster package for R). Six clusters of HIV prevention were identified: condom use (9,109 visits); low or no condom use, low PrEP (preexposure prophylaxis) use (6,258 visits); anal sex abstinence (746 visits); PEP (postexposure prophylaxis) and condom use (305 visits); PEP use (186 visits); and PrEP and condom use (176 visits). Most participants were aged 24 to 34 years old, were born in Portugal, had high education, and self-identified as gay. PrEP and PEP uptake were more associated with being born in Brazil, while low prevention adherence was less associated with high education. Condom use was the most frequently reported prevention strategy, followed by the low or no condom use, low PrEP use cluster. However, participants with higher odds of reporting HIV risk behaviors were the ones allocated to clusters with reports of higher frequency of prevention tools utilization.

Spatial variation of HIV testing and associated factors among pregnant women: a Spatial and multilevel analysis, DHS of sub-Saharan African countries

BACKGROUND

Human Immunodeficiency Virus (HIV) has infected an estimated of more 84 million individuals. Even though Sustainable Development Goal's 3 targets to end HIV/AIDS epidemics by year 2030, and many organizations work to eliminate mother-to-child transmission HIV/AIDS. Despite these efforts, Mother-to-child transmission of HIV continues as a major public health problem in sub-Saharan African countries.

METHODS

To recruit study participants, a two-stage stratified sampling procedure was used in conjunction with the Demographic Health Survey (DHS). A total of 118, 748 women were considered from the most recent DHS data of 33 sub-Saharan African countries. The data management and analysis was done using STATA V.17. ArcGIS version 10.7 and SaTScan version 10.1 software used for spatial analysis and SaTScan analysis, respectively. Multilevel logistic regression analysis was employed to account for the hierarchical nature of the DHS data. Deviance (-2LL) was applied to select the best fitted model.

RESULTS

HIV testing among pregnant women accounts about 87% in this study. The spatial hotspot indicates significantly low HIV testing areas found in Madagascar, Ethiopia, Democratic Republic of Congo, Guinea, Chad, Senegal, Mali, Mauritania, Niger, Burkina Faso and Angola. Age from 25 to 34 years (AOR = 1.82: 95% CI; 1.43, 2.32), being married (AOR = 3.69: 95% CI; 1.33, 10.20), media exposure (AOR = 1.47: 95% CI; 1.15, 1.88), having higher level of education (AOR = 1.83; 95% CI; 1.31, 2.55), richest wealth index (AOR = 6.24: 95% CI; 3.57, 10.90), working (AOR = 2.09: 95% CI; 1.67, 2.63), discriminatory attitude (AOR = 1.91: 95% CI; 1.48, 2.46), high risky sexual behavior (AOR = 3.23: 95% CI; 2.32, 5.74), visiting healthcare facilities (AOR = 1.63: 95% CI; 1.23, 2.16), early sexual initiation (AOR = 1.71: 95% CI; 1.15, 2.56), and community media exposure (AOR = 1.73: 95% CI; 1.10, 2.72), were significant factors associated with HIV testing in pregnant women, as shown from a multi-level analysis.

CONCLUSION

The prevalence of HIV testing among pregnant women was lower than expected by Sustainable Development Goal's 3 targets. Hotspot analysis indicates that most western African countries were areas of low HIV testing. Both individual and community level factors were found to be associated with HIV testing uptake significantly. Therefore, giving special attention for pregnant women in hotspot areas of SSA could increase HIV testing uptake.

Incidence of high blood pressure among Kenyan adults with HIV

OBJECTIVE

People with HIV (PWH) face a heightened risk of cardiovascular diseases, partly because of increased high blood pressure risk. This study assessed high blood pressure burden (i.e. incidence and prevalence) among PWH in Kenya over time.

DESIGN

Longitudinal, open cohort study.

METHODS

We estimated the incidence and prevalence of high blood pressure in a large sample of Kenyans with HIV from the Coptic Hope Center using electronic medical records from 2004 to 2023. We defined incident high blood pressure as first visit after baseline at which each patient had a SBP at least 140 mmHg and/or a DBP at least 90 mmHg.

RESULTS

Our sample included 38 709 PWH seeking care at Coptic Hope Center clinics in Kenya (2004-2023). Nearly 40% of patients had high blood pressure at first visit. Among the 60% of patients initially normotensive, almost 40% developed high blood pressure within 20 years. The yearly prevalence of high blood pressure ranged from 8 to 58%. Average SBP was higher among patients who had their first visit from 2019 to 2023 compared with those visiting in the early 2000s and 2010s.

CONCLUSION

Our findings reveal a high and rising burden of high blood pressure among PWH in a large, faith-based health system in Kenya. This underscores the need for stronger integration of care for individuals with concurrent HIV, high blood pressure, and other noncommunicable diseases (NCDs). Current systems are insufficient for achieving blood pressure control among PWH. Further research and funding for efforts to address HIV and NCD care in Kenya are warranted.

"I've Been Forged in Fire": Preliminary Theory of HIV Prevention Resilience Among Sexual Minority Men With HIV Risk Factors

HIV prevention research on sexual minority men focuses predominantly on risk factors, yet there is potential for enhancing HIV risk reduction by also examining resilience factors. We used mixed methods to explore HIV-related resilience pathways among 20 HIV-negative sexual minority men reporting HIV syndemic risks (childhood sexual abuse, partner abuse, mental health problems, substance abuse). Using grounded theory, we found that stress-related growth after mental health problems and/or unwanted sexual experiences can trigger development/use of HIV prevention resilience resources that, in turn, help sexual minority men cope and enhance HIV prevention behavior. We identified 23 HIV resilience resources at individual, interpersonal, community, health system, and structural levels. These findings informed a preliminary Theory of HIV Prevention Resilience for Sexual Minority Men. Our findings identified resilience resources to be nurtured through public health or mental health/substance use-focused interventions at broader levels to better address the HIV epidemic.

Explaining inequity in knowledge, attitude, and services related to HIV/AIDS: a systematic review

BACKGROUND

Equitable service provision and coverage are important responses to end the threat of the HIV/AIDS pandemic. Understanding inequity supports policies and programmes to deliver tailored interventions. There is continuous evidence generation on inequity in HIV/AIDS services. However, there was a lack of evidence on the global picture of inequity in behavioural and biomedical services related to HIV/AIDS. This systematic review assessed inequities in knowledge, attitude, HIV testing, and ART coverage across individual-level social groups and multiple (dis)advantage categories.

METHODS

This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline, with a PROSPERO registration number CRD42024521247. The risk of bias was assessed by using Hoy et al's and Joanna Brigg's quality appraisal checklists for cross-sectional quantitative and qualitative studies, respectively. The search date was from inception to the final database search date (May 29, 2023). The included articles were either quantitative or qualitative studies. We used mixed-methods approach to analyse the data from the review articles. Quantitative descriptive analysis was conducted to estimate frequency of articles published from different countries around the world. Qualitative content analysis of the findings from the original studies was conducted using the PROGRESS plus framework which stands for: place of residence, occupation or employment status, gender, religion, education status, socioeconomic status, and social capital.

RESULTS

Out of 6,029 articles that were accessed and screened, only 72 articles met the inclusion criteria. More articles on HIV-related equity in knowledge, attitude, testing, and ART were published in developed countries than in developing countries. Individuals from higher-income households had better knowledge about HIV/AIDS. Unfavourable attitudes towards people living with HIV and HIV/AIDS-associated stigma were common among women. HIV/AIDS service coverage (HIV testing or ART coverage) was higher among richer and urban residents. HIV/AIDS-associated stigma and lower levels of knowledge about HIV/AIDS were observed among multiple disadvantageous groups due to the intersection of two or more identities.

CONCLUSIONS

The current review revealed that there have been disparities in HIV/AIDS services between social classes. Ending service disparity towards the global threat of HIV/AIDS demands tailored interventions based on socially disadvantaged groups (e.g., poor, rural dwellers, and women) and intersectional determinants. There is a need to understand the deep-rooted causes of inequity and the challenges that an equity-oriented system faces over time. More studies on inequity are needed, including intersectional inequity, which has been rarely studied in developing countries.

Costing of a Combination Intervention (Kyaterekera) Addressing Sexual Risk-Taking Behaviors among Vulnerable Women in Southern Uganda

In Uganda, women engaged in sex work (WESW) are a marginalized population at the intersection of multiple vulnerabilities. The Kyaterekera intervention is targeted at WESW in Rakai and the greater Masaka regions in Uganda and combines a traditional HIV risk-reduction approach with a savings-led economic empowerment intervention and financial literacy training. We estimated the economic costs of the Kyaterekera intervention from a program provider perspective using a prospective activity-based micro-costing method. All program activities and resource uses were measured and valued across the control arm receiving a traditional HIV risk-reduction intervention and the treatment arm receiving a matched individual development savings account and financial literacy training on top of HIV risk reduction. The total per-participant cost by arm was adjusted for inflation and discounted at an annual rate of 3% and presented in 2019 US dollars. The total per-participant costs of the control and intervention arms were estimated at $323 and $1,435, respectively, using the per-protocol sample. When calculated based on the intent-to-treat sample, the per-participant costs were reduced to $183 and $588, respectively. The key cost drivers were the capital invested in individual development accounts and personnel and transportation costs for program operations, linked to WESW's higher mobility and the dispersed pattern of hot spot locations. The findings provide evidence of the economic costs of implementing a targeted intervention for this marginalized population in resource-constrained settings and shed light on the scale of potential investment needed to better achieve the health equity goal of HIV prevention strategies.

Advancing Adolescent and Young Adult HIV Prevention and Care and Treatment Through Use of Multi-level Theories and Frameworks: A Scoping Review and Adapted HIV Ecological Framework

While multi-level theories and frameworks have become a cornerstone in broader efforts to address HIV inequities, little is known regarding their application in adolescent and young adult (AYA) HIV research. To address this gap, we conducted a scoping review to assess the use and application of multi-level theories and frameworks in AYA HIV prevention and care and treatment empirical research. We systematically searched five databases for articles published between 2010 and May 2020, screened abstracts, and reviewed eligible full-text articles for inclusion. Of the 5890 citations identified, 1706 underwent full-text review and 88 met the inclusion criteria: 70 focused on HIV prevention, with only 14 on care and treatment, 2 on both HIV prevention and care and treatment, and 2 on HIV-affected AYA. Most authors described the theory-based multi-level framework as informing their data analysis, with only 12 describing it as informing/guiding an intervention. More than seventy different multi-level theories were described, with 38% utilizing socio-ecological models or the eco-developmental theory. Findings were used to inform the adaptation of an AYA World Health Organization multi-level framework specifically to guide AYA HIV research.

Exploring factors influencing the perspective regarding HIV transmission and prevention among college students in India

Objective and Design

Although many studies have been conducted to assess the knowledge and practices among healthcare workers, high-risk groups or medical students, very few studies have been conducted among college students from non-medical backgrounds. Our study aimed to assess the knowledge, attitudes and perception about human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) among the college students of the Mumbai region and to determine their association with the socio-demographic variables.

Setting and Methods

A cross-sectional online and offline questionnaire survey was conducted among 401 college students from the month of August 2022 to October 2022. Mean score and percentage were used to analyse the data.

Results

About 82.04% of participants exhibited good knowledge about HIV transmission and prevention, while 46.38% had a positive attitude towards HIV. Age, gender, religion and education had not influenced either knowledge or attitude significantly. Overall, knowledge score had a weak positive correlation with attitude of the participants.

Conclusion

Our study findings indicate that a holistic approach covering knowledge, psychological and societal health aspects is necessary among youth in India for positive changes in people's behaviour and achieving HIV prevention and management goals which will benefit public health at large.

Determination of knowledge, attitude and practice of voluntary counseling testing on HIV among youths from Tepi Town, Ethiopia

Objective

Voluntary counseling and testing (VCT) is an integral component of HIV prevention and care strategies worldwide. VCT is considered as an effective strategy in risk reduction among sexually active youth. There is a high burden of HIV in Ethiopia despite a considerable scale up of comprehensive HIV interventions. Hence, the aim of this study was to assess the level of knowledge, attitude and practice of VCT uptake towards HIV among youth of rural part of Tepi town, Ethiopia.

Method

A cross sectional study was carried out from May to August 2020. Total numbers of 127 youths in the age group of 15-24 years were recruited in a self-administered questionnaire with 100% response rate. Descriptive analysis was referred to describe the data. Binary logistic regression analysis was used to measure the effect of different variables by computing odds ratio. Multivariable analyses were utilized to determine the relative effect of explanatory variables.

Results

The study showed that out of 127 total youth respondents, 111 (87.4%) of the respondents have good knowledge and 99 (78%) had a positive attitude towards VCT. Whereas, 86 (67.7%) of the respondents are aware of practicing VCT on HIV in the past.

Conclusions

The findings revel that gender and father's educational status were among the socio-demographic variables that showed statistically significant association with one or more variables affecting youths' knowledge towards VCT uptake. As such, perceived risk of HIV infection, educational level, gender and marital status were statistically responsible for VCT uptake.

"It's already in your body and it's preventing": a qualitative study of African female adolescent's acceptability and preferences for proxy HIV prevention methods in Cape Town, South Africa

BACKGROUND

Advances in biomedical HIV prevention will soon offer young women a choice of HIV prevention methods, including various pre-exposure prophylaxis (PrEP) modalities such as daily oral pills, dapivirine vaginal ring, and long-acting injectable agents. By understanding preferences for contraceptive methods, we may draw analogies for the HIV prevention needs of young women. The UChoose Study was an open-label randomised cross-over study designed to evaluate the acceptability and preference for several contraceptive options as a proxy for HIV prevention methods that use similar types of administration. The study enrolled healthy HIV uninfected young women aged 15 to 19 years. At enrolment, participants were randomly assigned to a contraceptive method for a period of 16 weeks in the form of monthly Nuvaring® (vaginal ring), daily combined oral contraceptive (daily pills), or bi-monthly injectable contraceptive (injectable). After 16 weeks, participants crossed over to another contraceptive method, and those who had received the injectable and the daily pills received the vaginal ring for another 16 weeks, whereas those who had received the vaginal ring were able to choose between the injectable and daily pills, to ensure that all participants tried the vaginal ring-the least familiar option to the study population.

RESULTS

Thirty-three participants were purposively recruited to participate in seven focus group discussions (FGD) and completed a pre-survey for their assigned group. Our sample comprised 14 participants randomised to use of the vaginal ring and daily pills and 19 participants randomised to use of the vaginal ring and injectable. For most participants, their preferences for a prevention method were based primarily on their desire to avoid negative aspects of one method rather than their positive user experience with another method. Most participants expressed initial hesitancy for trying new contraception method products; however, a lack of familiarity was moderated by a strong interest in diverse user-controlled prevention methods. Participants valued methods that had infrequent dosing and simplified use requirements. The injection and vaginal ring were preferred over daily pills as a potential HIV prevention method.

CONCLUSION

Expanding the availability of diverse products could provide adolescents with multiple choices in HIV prevention for the uninitiated.

Relationships Between Stress-Responsive Biomarkers, ART Adherence, and Viral Suppression Among Adolescent Girls and Young Women Living With HIV in South Africa: An HPTN 068 Analysis

BACKGROUND

Adolescent girls and young women (AGYW) living with HIV who have higher stress levels may be at risk of stress-related biological alterations, which could influence HIV progression and adherence to antiretroviral therapy (ART).

SETTING

We aimed to estimate associations among stress-responsive biomarkers, ART adherence, and viral suppression in AGYW living with HIV in South Africa. We also hypothesized that psychosocial stressors [eg, depression, food insecurity, low socioeconomic status (SES), and HSV-2] would be associated with higher biomarker levels.

METHODS

We used 2018/2019 data from the HIV Prevention Trials Network 068 cohort to assess associations between stress-responsive biomarkers and viral suppression (<1000 copies/mL) and ART adherence measured using dried blood spot cards. Stress-responsive biomarkers included C-reactive protein, herpes simplex virus type 1, and cytomegalovirus infection and reactivation. Associations were estimated using unadjusted log-binomial or ordinal logistic regression models.

RESULTS

In 166 AGYW living with HIV, there was no association between stress-responsive biomarkers and viral suppression or ART adherence. However, increased C-reactive protein levels were associated with higher HSV-2 infection [odds ratio (OR) 1.98; 95% confidence interval (CI) 1.11, 3.52], being a government grant recipient (OR 3.21; 95% CI: 1.30, 7.92), lower food insecurity (OR 0.34; 95% CI: 0.13, 0.90), and increased body mass index (OR 1.07; 95% CI: 1.01, 1.14).

CONCLUSIONS

High prevalence of psychosocial stressors and persistent herpesviruses in AGYW living with HIV has the potential to lead to poorer health outcomes. More research is needed to untangle relationships between economic stability, chronic disease, and chronic stress.

Exploring the identities and experiences of young queer people in Mongolia using visual research methods

There is limited evidence about the lives of queer Mongolian youth. This is despite mental health problems being a pressing concern among young Mongolians, and international evidence suggesting queer youth may experience more mental health challenges than their non-queer peers. We explored the experiences of queer youth in their immediate environments and navigation of their identities in Mongolian society. In this study, twelve young queer-identifying people aged 18-25 from Ulaanbaatar, Mongolia participated in photo-elicitation interviews. Visual research methods allowed participants to generate rich (visual, textual, and oral) data about their lived experiences. We analysed data using a thematic approach and identified three main themes, each with three sub-themes. Participants reported that peer bullying and gendered expectations at school, heteronormativity and gender role expectation in family settings, along with strong stereotypes about queerness in broader society, substantially impacted participants' mental and physical wellbeing. Mongolian queer youth need strong support from their immediate environments, such as school and family. Stigma and misconception around queerness remain persistent among the public but young people are continuously resisting the prejudice expressed towards them. Understanding these challenges is crucial to increasing inclusivity in policies and programmes to enhance the wellbeing of young queer Mongolians.

HIV Prevention Tools Across the Pregnancy Continuum: What Works, What Does Not, and What Can We Do Differently?

PURPOSE OF REVIEW

Multiple tools exist to support the primary prevention of HIV in pregnant and postpartum women; however, there are opportunities to enhance their use and impact. This review summarizes the current status of HIV prevention tools and existing gaps and opportunities to improve their use along the pregnancy care continuum.

RECENT FINDINGS

HIV screening efforts have steadily improved with close to universal screening of pregnant women in several East and Southern African countries. Strategies to implement partner testing through the distribution of HIV self-test kits are promising though linkage to care remains challenging. Syphilis screening rates are increasing though detection of other sexually transmitted infections could benefit from improved diagnostic capacity. Male and female condoms are rarely used and are often not the optimal tool of choice during pregnancy. Oral pre-exposure prophylaxis (PrEP) is a promising tool, although barriers such as the need for daily adherence, side effects, and stigma may limit its use. There is a growing pipeline of PrEP agents with alternative delivery platforms that might suit women's preferences better and supports the notion that choice is vital to improving HIV prevention coverage during the pregnancy-postpartum continuum. Clear guidance on which tools to use and how to use them, safety data supporting their use, and surveillance data documenting the scale and effectiveness of the tools will be imperative in establishing a path to more impactful prevention efforts among pregnant and postpartum women.

Sexual behaviour changes and HIV infection among men who have sex with men: evidence from an open cohort in China

BACKGROUND

The HIV epidemic in key populations such as men who have sex with men (MSM) is a public health issue of worldwide concern. China has seen an increase in newly diagnosed HIV infections through male-male sexual contact in the past decade. In a long-term cohort, how the complex behaviour pattern of MSM changed and the association with the HIV risk are unclear at present.

METHODS

This study was conducted from October 2011 to December 2019 in Tianjin. MSM were recruited by snowball sampling through online and offline ways. Demographic and sexual behavioural data were collected for analysis. Three indicators (condom use in last anal sex, frequency of condom use during anal sex and the number of sexual partners) were used to define the behaviour change. Participants with zero, one, and two or three risk indicators were categorised into behaviour types of 'protective', 'moderate', and 'fragile', respectively. Change in behaviour type between baseline and each visit was considered. Time-varying Cox models were performed to evaluate HIV infection risk.

RESULTS

Of 2029 MSM included in the study, 127 were new HIV diagnoses. The overall incidence rate was 3.36 per 100 person-years. The percentage of 'protective' and 'moderate' behaviour types had a conspicuous growth trend as the follow-up. Furthermore, the HIV incidence rate in each visit among different behaviour transition types showed a general downward trend as the number of total follow-up times increased. Individuals who remained in 'fragile' (adjusted HR (aHR): 25.86, 95% CI: 6.92 to 96.57) or changed from 'protective' to 'moderate' (aHR: 4.79, 95% CI: 1.18 to 19.47), 'protective' to 'fragile' (aHR: 23.03, 95% CI: 6.02 to 88.13), and 'moderate' to 'fragile' (aHR: 25.48, 95% CI: 6.79 to 95.40) between baseline and the last follow-up had a higher HIV risk. Gained risk indicators were associated with the increase of HIV risk (gained one indicator, aHR: 2.67, 95% CI: 1.68 to 4.24; gained two or three indicators, aHR: 4.99, 95% CI: 3.00 to 8.31) while losing just one risk indicator could halve the risk (aHR: 0.43, 95% CI: 0.21 to 0.90).

CONCLUSIONS

Among MSM in Tianjin, it is necessary to get timely behaviour change for those with high-incidence behaviour patterns while sustaining for those with low-incidence patterns.

Assessing the Prevalence and Determinants of Exposure-Influenced HIV Testing among a Sample of Pre- and Post-Exposure Prophylaxis-Naïve Young Men Who Have Sex with Men in the United States

Self-initiated Human Immunodeficiency Virus (HIV) testing after potential sexual exposure to HIV (i.e., exposure-influenced HIV testing) has high utility in detecting individuals with the highest probabilities of HIV seroconversion. We conducted a cross-sectional study among a sample of sexually active, pre/post-exposure prophylaxis (PrEP/PEP)-naïve young men who have sex with men (YMSM) in two US cities to assess the determinants (e.g., demographic, psychosocial, sexual, substance use, and HIV prevention characteristics) of exposure-influenced HIV testing (never/rarely vs. mostly/always) in their lifetime. Of 261 YMSM, only 26.5% reported mostly/always seeking exposure-influenced prior to the study. Multivariable analyses showed that younger age, sexual orientation non-disclosure, perceived HIV stigma, internalized homophobia, lower general resilience, and lower social support were associated with a lower likelihood of mostly/always seeking exposure-influenced HIV testing. YMSM who never/rarely sought exposure-influenced HIV testing were more likely to use recreational drugs before sex, binge alcohol, and have group sex; while less likely to be aware of PrEP, test for sexually transmitted infections, or use condoms compared to those mostly/always seeking exposure-influenced HIV testing. Exposure-influenced HIV testing is suboptimal among YMSM with elevated risk for HIV. Our findings provide important implications for designing targeted interventions to promote exposure-influenced HIV testing among high-risk YMSM.

PrEP in the Context of Other HIV Risk Reduction Strategies Among Men Who Have Sex with Men: Results from the Flash! PrEP in Europe Survey

Combination HIV prevention covers a range of biomedical, behavioral, and socio-structural interventions. Despite the growing availability of pre-exposure prophylaxis (PrEP), it is not always accessible in European Centre for Disease Prevention and Control reporting countries and may not meet the needs of all at-risk populations. Based on the Flash! PrEP in Europe data, multiple correspondence analysis and hierarchical clustering were used to identify patterns in HIV prevention strategies among 9980 men who have sex with men (MSM). PrEP interest was evaluated among four identified clusters: (A) "high condom use, sometimes Treatment as Prevention (TasP)"; (B) "mix of methods, infrequent condom use"; (C) "high condom use, tendency to choose partners based on serological status" and (D) "moderate use of condoms mixed with other prevention strategies". Clusters B and D had higher PrEP interest. These results suggest that MSM use a range of behavioral and biomedical risk reduction strategies that are often combined. On-demand PrEP may meet the needs of MSM who infrequently use condoms and other prevention methods.

Sexually transmitted infection prevention behaviours: health impact, prevalence, correlates, and interventions

Sexually transmitted infections (STIs) remain a major public health threat, disproportionately affecting young people, and men who have sex with men. In this narrative review of the current state of behavioural science research on STI prevention, we consider the definition, health impacts, correlates and determinants, and interventions to promote STI prevention behaviour. Research on STI prevention behaviour has extended from a focus on abstinence, partner reduction and condom use, to also include novel preventive behaviours, notably treatment-as-prevention, pre-exposure prophylaxis (i.e., the preventive use of medicines by uninfected people), and vaccination for some STIs. Social-cognitive factors specified by, for instance the theory of planned behaviour, are critical proximal determinants of STI prevention behaviours, and related interventions can effectively promote STI prevention behaviours. Social-ecological perspectives highlight that individual-level determinants are embedded in more distal environmental influences, with social stigma especially affecting STI prevention behaviours and requiring effective intervention. Further to providing a major domain of application, STI prevention also poses critical challenges and opportunities for health psychology theory and research. We identify a need for health behaviour theory that addresses the processes linking multiple levels of influence on behaviour and provides practical guidance for multi-level behaviour change interventions adapted to specific contexts.

Is There Risk Compensation among HIV Infected Youth and Adults 15 Years and Older on Antiretroviral Treatment in South Africa? Findings from the 2017 National HIV Prevalence, Incidence, Behaviour and Communication Survey

In this paper, risk compensation among individuals on antiretroviral therapy (ART), using the 2017 South African national survey on HIV, is explored. A multi-stage stratified cluster random sampling approach was used to realize 11,130 participants 15 years and older. Logistic regression analysis assessed the association between multiple sexual partners, condom use at last sexual encounter, consistency of condom usage and potential explanatory variables using HIV status and ART exposure as a mediator variable. HIV positive participants who were aware and on ART were less likely to have multiple sexual partners, and less likely not to use a condom at last sex compared to HIV positive participants who were aware but not on ART. The odds of reporting multiple sexual partners were significantly lower among older age groups, females, non-Black Africans, and rural settings, and higher among those with tertiary level education, and risky alcohol users. The odds of no condom use at last sexual encounter were more likely among older age groups, females, other race groups, and less likely among those with secondary level education. The odds of inconsistent condom use were more likely among older age groups, females, and other race groups, and less likely among those with tertiary level education, high risk and hazardous alcohol users. Risk compensation is not apparent among HIV infected adults who are on ART. Risk groups that should receive tailored interventions to reduced risky sexual behaviours were identified.

A national recruitment strategy for HIV-serodiscordant partners living in Canada for the Positive Plus One study: a mixed-methods study

Background

With the recent shift in focus to addressing HIV risk within relationships and couple-based interventions to prevent HIV transmission, successful recruitment of individuals involved in HIV-serodiscordant relationships is crucial. This paper evaluates methods used by the Positive Plus One (PP1) study to recruit and collect data on a diverse national sample of dyads and individuals involved in current or past HIV-serodiscordant relationships, discusses the strengths and limitations of the recruitment approach, and makes recommendations to inform the interpretation of study results and the design of future studies.

Methods

PP1 used a multi-pronged approach to recruit adults involved in a current or past HIV-serodiscordant relationship in Canada from 2016 to 2018 to complete a survey and an interview. Upon survey completion, index (first recruited) partners were invited to recruit their primary current HIV-serodiscordant partner. We investigated participant enrollment by recruitment source, participant-, relationship-, and dyad-level sociodemographic characteristics, missing data, and correlates of participation for individuals recruited by their partners.

Results

We recruited 613 participants (355 HIV-positive; 258 HIV-negative) across 10 Canadian provinces, including 153 complete dyads and 307 individuals who participated alone, and representing 460 HIV-serodiscordant relationships. Among those in current relationships, HIV-positive participants were more likely than HIV-negative participants to learn of the study through an ASO staff member (36% v. 20%, p < 0.001), ASO listserv/newsletter (12% v. 5%, p = 0.007), or physician/staff at a clinic (20% v. 11%, p = 0.006). HIV-negative participants involved in current relationships were more likely than HIV-positive participants to learn of the study through their partner (46% v. 8%, p < 0.001). Seventy-eight percent of index participants invited their primary HIV-serodiscordant partner to participate, and 40% were successful. Successful recruitment of primary partners was associated with longer relationship duration, higher relationship satisfaction, and a virally suppressed HIV-positive partner.

Conclusions

Our findings provide important new information on and support the use of a multi-pronged approach to recruit HIV-positive and HIV-negative individuals involved in HIV-serodiscordant relationships in Canada. More creative strategies are needed to help index partners recruit their partner in relationships with lower satisfaction and shorter duration and further minimize the risk of “happy couple” bias.

The effectiveness of the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) in responding to HIV/AIDS in Four African Countries

BACKGROUND

The purpose of this study is to examine how PEPFAR's policies have changed and how these affects Human Immunodeficiency Virus (HIV)/Acquired Immune Deficiency Syndrome (AIDS) issue in two focus countries (Botswana and Ethiopia) and two non-focus countries (Zimbabwe and the Democratic Republic of Congo, or DR of Congo).

METHOD

This study investigates one country with the highest HIV rate (Botswana) and one with the lowest rates (Ethiopia) among the focus countries, as well as one each with the highest rate (Zimbabwe) and the lowest rate (DR Congo) among the non-focus countries.

RESULTS

This study finds that President's Emergency Plan for AIDS Relief (PEPFAR) has tended to change its strategies depending on a recipient country's epidemiology and has spent less in non-focus than in focus countries.

CONCLUSIONS

But by revealing the contributions and limitations of PEPFAR in four African countries, this study shows how PEPFAR can improve its future policies in these countries.

Behavioral and social interventions to promote optimal HIV prevention and care continua outcomes in the United States

PURPOSE OF REVIEW

This review reports on trends in behavioral and social intervention research in the United States published over the past year (2020-2021) investigating HIV prevention and care outcomes, organized by the level of intervention focus - individual, dyadic, and organizational.

RECENT FINDINGS

Researchers have continued to develop and evaluate behavioral and social interventions to reduce HIV acquisition risk and disease progression. With few exceptions, social and behavioral interventions have primarily focused on individuals as the unit of behavior change. Interventions operating at the individual-, dyadic-, and organizational-level have made strides to reduce HIV transmission risk and disease progressing by addressing mental health, substance use, stigma, peer and romantic relationships, and, to some extent, structural vulnerabilities.

SUMMARY

Social and behavioral interventions continue to be critical in addressing HIV inequities in the United States. An important gap in the literature is the need for multilevel interventions designed and implemented within existing community-based organizations and local healthcare settings. We call on researchers to continue to attend to the structural, environmental, and economic vulnerabilities that shape HIV inequities in the development of multilevel approaches necessary to realize the full potential of existing and emerging HIV prevention and care strategies.

A Counseling Mobile App to Reduce the Psychosocial Impact of Human Papillomavirus Testing: Formative Research Using a User-Centered Design Approach in a Low-Middle-Income Setting in Argentina

BACKGROUND

Human papillomavirus (HPV) testing detects sexually transmitted infections with oncogenic types of HPV. For many HPV-positive women, this result has negative connotations. It produces anxiety, fear of cancer or death, and disease denial. Face-to-face counseling could present many difficulties in its implementation, but a counseling mobile app could be practical and may help HPV-positive women reduce the psychosocial impact of the result, improve their knowledge of HPV and cervical cancer, and increase adherence to follow-up.

OBJECTIVE

This study aims to understand HPV-tested women's perceptions about an app as a tool to receive information and support to reduce the emotional impact of HPV-positive results. We investigated their preferences regarding app design, content, and framing.

METHODS

We conducted formative research based on a user-centered design approach. We carried out 29 individual online interviews with HPV-positive women aged 30 years and over and 4 focus groups (FGs) with women through a virtual platform (n=19). We shared a draft of the app's potential screens with a provisional label of the possible content, options menus, draft illustrations, and wording. This allowed us to give women understandable triggers to debate the concepts involved on each screen. The draft content and labels were developed drawing from the health belief model (HBM) and integrative behavioral model (IBM) variables and findings of mobile health literature. We used an FG guide to generate data for the information architecture (ie, how to organize contents into features). We carried out thematic analysis using constructs from the HBM and IBM to identify content preferences and turn them into app features. We used the RQDA package of R software for data processing.

RESULTS

We found that participants required more information regarding the procedures they had received, what HPV-positive means, what the causes of HPV are, and its consequences on their sexuality. The women mentioned fear of the disease and stated they had concerns and misconceptions, such as believing that an HPV-positive result is a synonym for cancer. They accepted the app as a tool to obtain information and to reduce fears related to HPV-positive results. They would use a mobile app under doctor or health authority recommendation. The women did not agree with the draft organization of screens and contents. They believed the app should first offer information about HPV and then provide customized content according to the users' needs. The app should provide information via videos with experts and testimonies of other HPV-positive women, and they suggested a medical appointment reminder feature. The app should also offer information through illustrations, or infographics, but not pictures or solely text.

CONCLUSIONS

Providing information that meets women's needs and counseling could be a method to reduce fears. A mobile app seems to be an acceptable and suitable tool to help HPV-positive women.

Optimal Control Strategies and Sensitivity Analysis of an HIV/AIDS-Resistant Model with Behavior Change

Despite several research on HIV/AIDS, it is still incumbent to investigate more effective control measures to mitigate its infection level. Therefore, we introduce an HIV/AIDS-resistant model with behavior change and study its basic properties. In order to determine the most sensitive parameters that are responsible for disease transmission with respect to the basic reproduction number and those responsible for disease prevalence with respect to the endemic equilibrium, the sensitivity analysis was established and it was confirmed that the influx rate of people into the infected population and total abstinence from all risk practices and endemic areas are some of the most sensitive parameters for disease spread and disease eradication, respectively. Furthermore, by considering controls [Formula: see text] denoting the government's intervention in promoting and encouraging behavior change, [Formula: see text] representing intake of balanced nutritional supplementation, and [Formula: see text] connoting antiretroviral therapy (ART), an optimal control problem was developed and analyzed. Before the establishment of the necessary conditions of the optimal control using Pontryagin's Maximum Principle, we proved the existence of the optimal control triplet [Formula: see text] where [Formula: see text] is the control set at time t,) which has been neglected by many researchers in recent years. Using the Runge-Kutta scheme, the optimal control problem was solved to understand the best combination of control strategies. Using the demographic and epidemiological data for South Africa on HIV/AIDS, a numerical simulation was carried out and results are presented on 3D surface plots. The obtained results suggested that the combination of all the considered control measures is the best method to ensure disease eradication.

Comprehensive knowledge and HIV prevalence in two migrant mineworkers' communities of origin in Gaza Province in Southern Mozambique: evidence from a cross-sectional survey

Introduction

migrant mine workers are susceptible to engage in risky sexual behaviour due to their high mobility, putting at risk their families and home communities. Because comprehensive knowledge about HIV/AIDS is a key factor in reducing HIV infections, this study aims to understand the current state of knowledge about HIV in these communities, estimate HIV prevalence and evaluate the risk behaviour associated with comprehensive knowledge.

Methods

secondary data analysis of a cross-sectional survey conducted in two communities of origin of mine workers in Gaza Province, targeting current and former mine workers of the South African mines and their relatives. Households were selected using simple random sampling methodology. Chi-squared tests and logistic regression analysis were used to assess statistical differences between comprehensive knowledge and categorical variables.

Results

from a total of 1,012 participants, only 22.0% of the respondents had comprehensive knowledge about HIV. The overall HIV prevalence in these communities was 24.2% and the HIV prevalence in individuals with comprehensive knowledge was 18.6%. Among the respondents with comprehensive knowledge, 33.1% were male, 22.0% have worked in a South African mine and the median age was 34 years old. Individuals from Muzingane were almost twice as likely (AOR 1.7; 95% IC 1.21-7.44, p=0.014) to have less comprehensive knowledge about HIV than their counterparts in Patrice Lumumba.

Conclusion

the results demonstrate a low level of comprehensive knowledge about HIV amongst this population and reveal an association between comprehensive knowledge about HIV and prevalence. Therefore, it is important to improve knowledge about HIV, its transmission and prevention amongst this population.

A Game Theoretic Analysis of Competition Between Vaccine and Drug Companies during Disease Contraction and Recovery

Background

Infectious diseases such as COVID-19 and HIV/AIDS are behaviorally challenging for persons, vaccine and drug companies, and donors.

Methods

In 3 linked games in which a disease may or may not be contracted, N persons choose risky or safe behavior (game 1). Two vaccine companies (game 2) and 2 drug companies (game 3) choose whether to develop vaccines and drugs. Each person chooses whether to buy 1 vaccine (if no disease contraction) or 1 drug (if disease contraction). A donor subsidizes vaccine and drug developments and purchases. Nature probabilistically chooses disease contraction, recovery versus death with and without each drug, and whether vaccines and drugs are developed successfully. COVID-19 data are used for parameter estimation.

Results

Each person chooses risky behavior if its utility outweighs safe behavior, accounting for nature’s probability of disease contraction which depends on how many are vaccinated. Each person buys a vaccine or drug if the companies produce them and if their utilities (accounting for side effects and virus mutation) outweigh the costs, which may be subsidized by a sponsor.

Discussion

Drug purchases depend on nature’s recovery probability exceeding the probability in the absence of a drug. Each company develops and produces a vaccine or drug if nature’s probability of successful development is high, if sufficiently many persons buy the vaccine or drug at a sales price that sufficiently exceeds the production price, and if the donor sponsors.

Conclusion

Accounting for all players’ interlinked decisions allowing 14 outcomes, which is challenging without a game theoretic analysis, the donor maximizes all persons’ expected utilities at the societal level to adjust how persons’ purchases and the companies’ development and production are subsidized.

Highlights

A Systematic Review of Randomized Controlled Trials of School Based Interventions on Sexual Risk Behaviors and Sexually Transmitted Infections Among Young Adolescents in Sub-Saharan Africa

Young adolescents in Sub-Saharan Africa (SSA) are at high risk of involvement in sexual risk behaviors; and curable sexually transmitted infections (STI), herpes simplex virus type 2 (HSV-2), human immunodeficiency virus (HIV) and unintended pregnancies remain persistently high in this population. Evidence based strategies are urgently needed to improve these outcomes. The aim of this systematic review was to synthesize the evidence from randomized controlled trials (RCT) to determine whether school-based interventions promote safe sex behaviors, reduce sexual risk behaviors and risk of curable STIs, HSV-2, HIV and unintended pregnancies among young adolescents aged 9-19 years in SSA. Electronic databases were searched for published studies and manual searches were conducted through reviewing of references of cited literature in the English language up to December 2019. Two independent reviewers screened and abstracted the data. We identified 428 articles and data from nine RCTs (N = 14,426 secondary school students) that fulfilled the selection criteria were analysed. Two studies measured pregnancy as an outcome and showed significant declines in unintended pregnancies. Of the five studies that measured HIV/AIDS related-knowledge, condom-use outcomes (normative beliefs, knowledge, and self-efficacy) and attitudes to HIV testing, four showed significant improvements. Of the six studies that measured sexual debut, four reported moderate but non-significant declines and in two studies sexual debut information was either incomplete or unreliable. One study measured curable STIs and found no significant declines; whilst the second study that measured HSV-2 and HIV, no significant declines were observed. This review highlights the need to undertake well-designed research studies to provide evidence on the impact of interventions on curable STIs, HSV-2 and HIV, critical to improving the health of young adolescents.

Reducing HIV/STI Risk Among Adolescents Aged 12 to 14 Years: a Randomized Controlled Trial of Project Prepared

Despite calls for evidence-based HIV/STI prevention programs for youth aged 12 to 14 transitioning to adolescence, few effective programs exist. In a two-group intent-to-treat randomized trial in the Bronx, NY, 397 participants were randomly assigned to Project Prepared or an attention control, TEEN. Participants completed surveys at baseline, 6 months, and 12 months. Prepared had two components, an 11-session program and a 3-week internship. Content covered sexual risk behavior, social cognitions, gender norms, relationships, and resilience. TEEN built communication skills and had the same intensity and structure as Prepared but no sexual content. In both, boys and girls were trained together in mixed groups of ~ 11 teens. Primary outcomes were HIV knowledge, self-efficacy, condom outcome expectancy, and behavioral intentions. Secondary outcomes were relationship expectations and endorsement of risky gender norms. Generalized estimating equation analyses showed youth randomized to Prepared had significant improvements compared to TEEN at T2 in HIV knowledge, sexual self-efficacy, and outcome expectancy for condom use. At T3, there were significant differences favoring Prepared in outcome expectancy for condom use, sexual self-efficacy, and intention for partner communication about HIV/AIDS or STIs. Analyses by gender showed program effects in both boys (intention to talk to a partner about condom use, abstinence self-efficacy, sexual self-efficacy, and condom outcome expectancy) and girls (gender norms, and abstinence outcome expectancy). Prepared effectively reduced risk in young adolescents. ClinicalTrials.gov ID: NCT01880450, Protocol ID: 2008-551.

Stakeholder acceptability of the risk reduction behavioural model [RRBM] as an alternative model for adolescent HIV risk reduction and sexual behavior change in Northern Malawi

We sought to assess stakeholder acceptability of a risk reduction behavioural model [RRBM] designed for adolescent HIV risk reduction and whose efficacy we tested in selected schools in Northern Malawi. We used qualitative procedures in sampling, data collection and data analysis. Our data collection instrument was the semi-structured interview and we applied thematic content analysis to establish stakeholder evaluations of the RRBM model. The study population included10 experts working within key organizations and teachers from two schools. The organizations were sampled as providers, implementers and designers of interventions while schools were sampled as providers and consumers of interventions. Individual study participants were recruited purposively through snowball sampling. Results showed consensus among participants on the acceptability, potential for scale up and likelihood of model sustainability if implemented. In essence areas to consider improving and modifying included: focus on the rural girl child and inclusion of an economic empowerment component to target the underlying root causes of HIV risk taking behavior. Stakeholders also recommended intervention extension to out of school adolescent groups as well as involvement of traditional leaders. Involvement of parents and religious leaders in intervention scale up was also highlighted. The study serves as a benchmark for stakeholder involvement in model and intervention evaluation and as a link between researchers and project implementers, designers as well as policy makers to bridge the research to policy and practice gap.

Recurrent Sexually Transmitted Infections Among a Cohort of Men Who Have Sex With Men Using Preexposure Prophylaxis in Belgium Are Highly Associated With Sexualized Drug Use

BACKGROUND

Men who have sex with men (MSM) experiencing recurrent sexually transmitted infections (STIs) may play a crucial role in the STI epidemic. However, there is limited understanding of what kind of behavior leads to recurrent STIs.

METHODS

A total of 179 MSM using preexposure prophylaxis were followed up for 18 months and were screened quarterly for chlamydia, gonorrhea, and syphilis from 2015 to 2018 in Belgium. Participants were stratified into 3 different groups (no STI, one STI episode, recurrent STI episodes during the study). Sociodemographic and sexual behavioral characteristics were compared between the 3 groups, and significant associations with recurrent STI were explored using multivariate logistic regression models.

RESULTS

A total of 62.0% (n = 111/179) of participants experienced at least one STI during the study, and more than 1 in 3 became reinfected with an STI at another visit (n = 66/179 [36.9%]). Participants experiencing recurrent STIs reported the highest frequency of sexualized drug use (86.4%) compared with participants experiencing one (60.0%) or no STI (47.1%). Therefore, sexualized drug use was highly associated with recurrent STIs (adjusted odds ratio [aOR]. 4.35). Other factors associated with recurrent STIs were being younger than 40 years (aOR, 3.29), had a high number (>4) of nonsteady partners with whom receptive (aOR, 1.17) or insertive (aOR, 1.12) condomless anal intercourse occurred in the last 3 months.

CONCLUSIONS

Sexualized drug use was the greatest risk factor for having recurrent STIs. Tailoring prevention and care, including specialized services tackling problematic drug use in a sexual context, may help to curb the STI epidemic among MSM.

An individually randomized controlled trial of a mother-daughter HIV/STI prevention program for adolescent girls and young women in South Africa: IMARA-SA study protocol

BACKGROUND

South Africa has the world's largest HIV epidemic, but South African adolescent girls and young women (AGYW) acquire HIV at twice the rate of and seroconvert on average 5-7 years earlier than their male peers. Female caregivers (FC) are an untapped resource for HIV/STI prevention in South Africa and offer a novel opportunity to strengthen AGYW prevention efforts. This study will evaluate the effectiveness and cost-effectiveness of an evidence-based mother-daughter HIV/STI prevention program tested in the United States and adapted for South Africa, Informed Motivated Aware and Responsible Adolescents and Adults (IMARA), to decrease STI incident infections and increase HIV testing and counseling (HTC) and PrEP uptake in AGYW.

METHODS

This is a 2-arm individually randomized controlled trial comparing IMARA to a family-based control program matched in time and intensity with 525 15-19-year-old Black South African AGYW and their FC-dyads in Cape Town's informal communities. AGYW will complete baseline, 6-, and 12-month assessments. Following randomization, AGYW-FC dyads will participate in a 2-day group workshop (total 10 h) that includes joint and separate mother and daughter activities. Primary outcomes are AGYW STI incidence, HTC uptake, and PrEP uptake at 6 months. Secondary outcomes are AGYW STI incidence, HTC uptake, and PrEP uptake at 12 months, sexual behavior (e.g., condom use, number of partners), HIV incidence, and ART/PrEP adherence and intervention cost-effectiveness. AGYW who test positive for a STI will receive free treatment at the study site. HIV positive participants will be referred to ART clinics.

DISCUSSION

Primary prevention remains the most viable strategy to stem new STI and HIV transmissions. HIV and STI disparities go beyond individual level factors, and prevention packages that include supportive relationships (e.g., FC) may produce greater reductions in HIV-risk, improve HTC and PrEP uptake, and increase linkage, retention, and adherence to care. Reducing new HIV and STI infections among South African AGYW is global public health priority.

Knowledge, attitude, and preferred strategies towards HIV/AIDS prevention among adolescents attending secondary schools in South Western Uganda

BACKGROUND

Globally, HIV/AIDS continues to rise among adolescents. Ugandan studies have examined knowledge and attitudes regarding HIV/AIDS among adult populations. This study specifically paid attention to this particular age group of adolescents 12-19 years.

AIM

To explore HIV knowledge and attitudes among adolescents attending secondary schools Mbarara Uganda.

METHODS

A qualitative descriptive study was conducted in three secondary schools in South Western Uganda. Forty eight (48) adolescents with age range between 12-19 years were purposively recruited in the study. Data were collected from six focus groups and analyzed thematically. Ethical approval received from MUST (#05/10-17) and UNSCT (#SS4535) review committees.

RESULTS

Four themes emerged: Knowledge about HIV, sources of information, attitudes towards persons with HIV and prevention strategies. Most adolescents had the basic knowledge of HIV from multiple sources like social media, health workers, peers, and parents. Their attitudes toward individuals with HIV included compassion, shock, and uneasiness. Participants suggested prevention programs to be implemented in the schools emphasizing HIV education, life skills, sex education and the formation of peer groups.

CONCLUSIONS

The findings showed that most participants had knowledge about HIV and how it can be prevented however few had knowledge gap thinking that HIV does not exist.

Client perspectives on an outreach approach for HIV prevention targeting Indonesian MSM and transwomen

This study explored clients’ perspective on an outreach approach to promote HIV testing in Indonesia targeting men who have sex with men (MSM) and transgender women (transwomen or waria). Semi-structured qualitative interviews were conducted with 32 individuals (21 MSM and 11 waria) who had received services from outreach workers (OWs) in five cities in Indonesia. Participants in this study reported positive experiences with the outreach approach and perceived OWs as their motivators in accessing HIV testing as well as HIV care and treatment. OWs provided easy-to-understand HIV information. Clients expected OWs to be well-trained and more creative in performing outreach. They perceived that the Internet and social media have helped them considerably to stay in touch with OWs. Yet, they expressed that such virtual contacts could not simply replace the face-to-face contact, especially for waria. Furthermore, clients suggested outreach to be delivered in a more appealing manner, for example through activities that may facilitate clients learning professional or life skills. They also asserted that as an HIV prevention approach, outreach needs to use more positive framing and go beyond HIV and health contents, chiefly for the youth. Future outreach programmes should facilitate OWs in providing tailored services based on the level and type of support that the clients need, and in applying varied proportion and levels of sophistication in the use of online and virtual platforms for outreach.

Decisions of persons, the pharmaceutical industry, and donors in disease contraction and recovery assuming virus mutation

BACKGROUND

The article develops an eight-period game between N persons and a pharmaceutical company. The choices of a donor and Nature are parametric.

METHODS

Persons choose between safe and risky behavior, and whether or not to buy drugs. The pharmaceutical company chooses whether or not to develop drugs. The donor chooses parametrically whether to subsidize drug purchases and drug developments. Nature chooses disease contraction, recovery, death, and virus mutation. The game is solved with backward induction.

RESULTS

The conditions are specified for each of seven outcomes ranging from safe behavior to risky behavior and buying no or one or both drugs. The seven outcomes distribute themselves across three outcomes for the pharmaceutical company, which are to develop no drugs, develop one drug, and develop two drugs if the virus mutates. For these three outcomes the donor's expected utility is specified.

CONCLUSION

HIV/AIDS data is used to present a procedure for parameter estimation. The players' strategic choices are exemplified. The article shows how strategic interaction between persons and a pharmaceutical company, with parametric choices of a donor and Nature, impact whether persons choose risky or safe behavior, whether a pharmaceutical company develops no drugs or one drug, or two drugs if a virus mutates, and the impact of subsidies by a donor.

Progress toward HIV elimination goals: trends in and projections of annual HIV testing and condom use in Africa

OBJECTIVES

To estimate trends in and projections of annual HIV testing and condom use at last higher-risk sex and to calculate the probability of reaching key United Nations Programme on AIDS (UNAIDS)'s target.

DESIGN

We included 114 nationally-representative datasets in 38 African countries from Demographic and Health Surveys and Multiple Indicator Cluster Surveys with 1 456 224 sexually active adults age 15-49 from 2003 to 2018.

METHODS

We applied Bayesian mixed effect models to estimate the coverage of annual HIV testing and condom use at last higher-risk sex for every country and year to 2030 and the probability of reaching UNAIDS testing and condom use targets of 95% coverage by 2030.

RESULTS

Seven countries saw downward trends in annual HIV testing and four saw decreases in condom use at higher-risk sex, whereas most countries have upward trends in both indicators. The highest coverage of testing in 2030 is predicted in Swaziland with 92.6% (95% credible interval: 74.5-98.1%), Uganda with 90.5% (72.2-97.2%), and Lesotho with 90.5% (69.4%-97.6%). Meanwhile, Swaziland, Lesotho, and Namibia will have the highest proportion of condom use in 2030 at 85.0% (57.8-96.1%), 75.6% (42.3-93.6%), and 75.5% (42.4-93.2%). The probabilities of reaching targets were very low for both HIV testing (0-28.5%) and condom use (0-12.1%).

CONCLUSIONS

We observed limited progress on annual HIV testing and condom use at last higher-risk sex in Africa and little prospect of reaching global targets for HIV/AIDS elimination. Although some funding agencies are considering withdrawal from supporting Africa, more attention to funding and expanding testing and treatment is needed in this region.

Effect of Biomedical Materials in the Implementation of a Long and Healthy Life Policy

This paper is divided into seven main parts. Its purpose is to review the literature to demonstrate the importance of developing bioengineering and global production of biomaterials to care for the level of healthcare in the world. First, the general description of health as a universal human value and assumptions of a long and healthy life policy is presented. The ethical aspects of the mission of medical doctors and dentists were emphasized. The coronavirus, COVID-19, pandemic has had a significant impact on health issues, determining the world’s health situation. The scope of the diseases is given, and specific methods of their prevention are discussed. The next part focuses on bioengineering issues, mainly medical engineering and dental engineering, and the need for doctors to use technical solutions supporting medicine and dentistry, taking into account the current stage Industry 4.0 of the industrial revolution. The concept of Dentistry 4.0 was generally presented, and a general Bioengineering 4.0 approach was suggested. The basics of production management and the quality loop of the product life cycle were analyzed. The general classification of medical devices and biomedical materials necessary for their production was presented. The paper contains an analysis of the synthesis and characterization of biomedical materials supporting medicine and dentistry, emphasizing additive manufacturing methods. Numerous examples of clinical applications supported considerations regarding biomedical materials. The economic conditions for implementing various biomedical materials groups were supported by forecasts for developing global markets for biomaterials, regenerative medicine, and tissue engineering. In the seventh part, recapitulation and final remarks against the background of historical retrospection, it was emphasized that the technological processes of production and processing of biomedical materials and the systematic increase in their global production are a determinant of the implementation of a long and healthy policy.

A Review of Recent HIV Prevention Interventions and Future Considerations for Nursing Science

ABSTRACT

As our knowledge of HIV evolved over the decades, so have the approaches taken to prevent its transmission. Public health scholars and practitioners have engaged in four key strategies for HIV prevention: behavioral-, technological-, biomedical-, and structural/community-level interventions. We reviewed recent literature in these areas to provide an overview of current advances in HIV prevention science in the United States. Building on classical approaches, current HIV prevention models leverage intimate partners, families, social media, emerging technologies, medication therapy, and policy modifications to effect change. Although much progress has been made, additional work is needed to achieve the national goal of ending the HIV epidemic by 2030. Nurses are in a prime position to advance HIV prevention science in partnership with transdisciplinary experts from other fields (e.g., psychology, informatics, and social work). Future considerations for nursing science include leveraging transdisciplinary collaborations and consider social and structural challenges for individual-level interventions.

Reaching a Different Population of MSM in West Africa With the Integration of PrEP Into a Comprehensive Prevention Package (CohMSM-PrEP ANRS 12369-Expertise France)

BACKGROUND

In West Africa, few HIV services target men who have sex with men (MSM). In 2015, the interventional cohort CohMSM started offering a community-based prevention package for MSM. Participants expressed interest in pre-exposure prophylaxis (PrEP) and their eligibility was demonstrated. In 2017, PrEP was added to services already offered as part of a new program, CohMSM-PrEP, which recruited CohMSM participants and new participants. We aimed to determine whether the introduction of PrEP as an additional prevention tool influenced the type of participant signing up for CohMSM-PrEP.

METHODS

CohMSM-PrEP recruited HIV-negative MSM in community-based clinics in Mali, Cote d'Ivoire, Burkina Faso, and Togo. Quarterly follow-up included free clinical examinations, PrEP, HIV/sexually transmitted infection screening, peer education, condoms, and lubricants. Sociobehavioral data were collected every 3 months using face-to-face questionnaires. Our outcome was participant type: new participants vs CohMSM participants. Logistic regression was performed to identify the factors associated with being a new participant.

RESULTS

Of the 524 MSM included in CohMSM-PrEP, 41% were new participants. After adjustment, multivariate analysis showed they were more socioeconomically disadvantaged with financial insecurity, social isolation-including isolation within the MSM community-and riskier sexual practices.

CONCLUSION

The introduction of PrEP as an additional prevention tool and the use of peer-based outreach services over time influenced the type of participant signing up for a community-based HIV prevention cohort in West Africa. Adding these elements to existing interventions in Sub-Saharan Africa could be the key to reaching MSM marginalized from HIV prevention and care programs.

Drug Injection-Related and Sexual Behavior Changes in Drug Injecting Networks after the Transmission Reduction Intervention Project (TRIP): A Social Network-Based Study in Athens, Greece

The Transmission Reduction Intervention Project (TRIP) was a network-based, enhanced contact tracing approach, targeting recently HIV-infected people who inject drugs (PWID) in Athens, Greece (2013–2015). This analysis examines behavioral changes of participants in TRIP and their determinants between baseline and follow-up visits to the program. All participants of TRIP were tested for HIV and interviewed using a questionnaire with items on drug injection-related and sexual behaviors. Multivariable logistic regression models were used to examine potential relationships between participants’ behaviors and sociodemographic or other characteristics. The analysis included 292 participants. At follow-up, the percentage of participants who injected drugs decreased [92.5%, n = 270 versus 72.3%, n = 211 (p < 0.001)], and more participants adopted safer behaviors. Employment, age, and gender were significantly associated with some behavioral changes. For instance, unemployed participants were half as likely as the employed to stop drug injection [adjusted odds ratio (aOR): 0.475, 95% confidence interval (CI): 0.228, 0.988]. Increasing age was associated with lower probability of sharing syringes at follow-up (aOR: 0.936, 95%CI: 0.887, 0.988). Finally, females were less likely than males to improve their behavior related to sharing cookers, filters, or rinse water (aOR: 0.273, 95% CI: 0.100, 0.745). In conclusion, adoption of safer behaviors was observed following TRIP implementation. Future prevention programs should focus on younger PWID and especially females. Social efforts to support employment of PWID are also important.

A review of current strategies to improve HIV prevention and treatment in sexual and gender minority Latinx (SGML) communities

INTRODUCTION

The HIV epidemic continues to disproportionately impact sexual and gender minority Latinxs (SGML). Several syndemic conditions have been linked with HIV acquisition and transmission among SGML including immigration, discrimination, environmental racism, substance use, and mental health.

AREAS COVERED

We provide a summary of biomedical, behavioral, and social/structural interventions to reduce risks for acquiring HIV and improve outcomes along the HIV care continuum among SGML. We also discuss intervention approaches and opportunities that respond at the intersection of HIV and COVID-19 prevention and treatment.

EXPERT OPINION

There is a dire need for the combination of biomedical, behavioral, and social/structural interventions to reduce risks for acquiring HIV and improve outcomes along the HIV care continuum. Interventions and combination approaches should be driven by community-based participatory action research. The inclusion of community members in all stages of the research process can assure successful implementation of program activities and deliverables, including the provision of culturally and linguistically appropriate services. Given the current COVID-19 pandemic, which is disproportionately impacting individuals living with HIV and other comorbidities, the elderly, and under-resourced communities with a ferocity not seen in other communities, intervention approaches that respond at the intersection of HIV and COVID-19 prevention and treatment are also urgently needed.

Prevalence and Associated Factors of HIV Testing Among Pregnant Women: A Multilevel Analysis Using the Recent Demographic and Health Survey Data from 11 East African Countries

Aim

In developing countries, particularly in sub-Saharan Africa, the burden of mother to child transmission (MTCT) of HIV is higher. Although the Joint United Nations Programme on HIV/AIDS (UNAIDS) and other organizations are working to eliminate MTCT, a large number of pregnant women are not screened for HIV in most African countries.

Methods

The demographic health survey (DHS) used two-stage stratified sampling technique to select the study participants and we appended the most recent DHS done in the 11 East African countries. A weighted sample of 53, 420 women were included. A multilevel logistic regression analysis was used due to the hierarchical structure of the DHS data. To determine whether or not there was a clustering, the Interclass Correlation Coefficient (ICC) and Median Odds Ratio (MOR) were determined. Model comparison was conducted using deviance (−2LL).

Results

The prevalence of HIV testing among pregnant women was 77.56% [95% CI= 77.20%, 77.91%]. In the Multivariable multi-level analysis, variables such as respondent age, wealth index, marital status, educational level, HIV knowledge, HIV stigma indicator, risky sexual activity, women visiting health care facilities, multiple sexual partnership, early sexual initiation, and awareness about MTCT were the individual-level factors that were associated with HIV testing among pregnant women. While residence and community-level education were the community-level factors that were significantly associated with HIV testing.

Conclusion

The prevalence of HIV testing and counseling among pregnant women was higher compared to the previous report. Respondent age, wealth index, marital status, educational level, HIV knowledge, HIV stigma indicator, risky sexual activity, women visiting health care facilities, multiple sexual partnership, early sexual initiation, residence, community-level education and awareness about MTCT were the significant determinant of HIV testing.

Added Benefits of Pre-Exposure Prophylaxis Use on HIV Incidence with Minimal Changes in Efficiency in the Context of High Treatment Engagement Among Men Who Have Sex with Men

Although there is ongoing debate over the need for substantial increases in pre-exposure prophylaxis (PrEP) use when antiretroviral treatment confers the dual benefits of reducing HIV-related morbidity and mortality and the risk of HIV transmission, no studies to date have quantified the potential added benefits of PrEP use and changes in its efficiency in the context of high treatment engagement across multiple US subpopulations. We used a previously published agent-based model to simulate HIV transmission in a dynamic network of Black/African American and White men who have sex with men (MSM) in Atlanta, Georgia (2015-2024) to understand how reductions in HIV incidence attributable to varying levels of PrEP use change when United Nations Joint Programme on HIV/AIDS (UNAIDS) "90-90-90" goals for HIV treatment are achieved and maintained. Even at achievement of "90-90-90" goals, 75% PrEP coverage further reduced incidence by 67.9% and 74.2% to 1.53 [simulation interval (SI): 1.39-1.70] and 0.355 (SI: 0.316-0.391) per 100 person-years for Black/African American and White MSM, respectively, compared with the same scenario with no PrEP use. Increasing PrEP coverage from 15% to 75% under "90-90-90" goals only increased the number of person-years of PrEP use per infection averted by 8.1% and 10.5% to 26.7 (SI: 25.6-28.0) and 73.3 (SI: 70.6-75.7) among Black/African American MSM and White MSM, respectively. Even with high treatment engagement, substantial expansion of PrEP use contributes to meaningful decreases in HIV incidence among MSM with minimal changes in efficiency.

Interprofessional collaboration associated with frequency of life-saving links to HIV continuum of care services in the urban environment of Newark, New Jersey

BACKGROUND

HIV continuum of care has been used as a strategy to reduce HIV transmission rates, with timely engagement in HIV testing being the first and most critical step. This study examines interprofessional-collaboration (IPC) after controlling for agency/ provider demographics, provider training and self-efficacy as a significant predictor of how frequently HIV service providers link their clients to HIV testing.

METHODS

Multilevel binary logistic regression analysis was conducted to examine the effects of IPC on links to HIV testing while controlling for demographic and agency information, provider training, and standardized measures of providers' feelings, attitudes, and opinions about IPC. Cross-sectional data from 142 providers in 13 agencies offering treatment and prevention services for HIV and substance-use disorders were collected via a survey.

RESULTS

Those who scored higher on the IPC scale reported significantly higher rates of linkages to HIV testing. Compared to the null model (i.e., no predictor model), the final multilevel binary logistic regression model showed a significantly improved likelihood of linkage to HIV testing by 11.4%, p. < .05. The final model correctly classified 90.2% of links to HIV testing. Providers in agencies with smaller budgets and in agencies offering substance use disorder services were more likely to link clients to HIV testing. Younger providers who received HIV training were also more likely to link clients to HIV testing.

CONCLUSIONS

Findings suggest IPC training as a potential strategy to improve linkages to HIV testing for clients at risk for HIV infection. Future research is recommended to identify specific areas of IPC that might have differential effects on links to HIV testing.

Does Women's Autonomy Matter on Attitude Towards Condom Use in Reducing Risk for HIV Infection Among Married Women in Ethiopia?

Background

Condom utilization remains as the forefront guard to reduce the HIV/AIDS pandemic. However, evidence showed that the dynamics of gendered power, beliefs, and attitudes about condoms and sexuality retards condom use for a large proportion of Africa's people. Therefore, this study aimed to assess the association between women's autonomy in health decision making and attitude to condom use in reducing risk for HIV in Ethiopia using a nationally representative, population-based household survey data.

Methods

A cross-sectional study was carried out using 2016 nationally representative, population-based Ethiopia Demographic and Health Survey. SPSS version 21 was used to analyze the data. Multivariate logistic regression analysis was performed to assess the association between women's autonomy in health decision making and attitude to condom use by controlling confounders. To declare statistically significant associations, adjusted odds ratios (AOR) with 95% confidence interval (CI) were used.

Results

The present study enrolled 6787 weighted samples of married women. The study showed that the odds of attitude toward condom use were 1.39 times (AOR: 1.39; 95% CI: 1.04-1.85) higher among women who decide for their health care compared to its counterparts. Also, the odds of attitude toward condom use were positively associated among women who conquered higher education (AOR: 1.97; 95% CI: 1.17-3.33), who had the richest wealth index quintile (AOR: 1.45; 95% CI: 1.01-2.07), and who had ever been tested for HIV (AOR: 1.31; 95% CI: 1.09-1.57). However, the odds of attitudes toward condom use were negatively associated among Muslims (AOR: 0.58; 95% CI: 0.46-0.74) and Protestant religion (AOR: 0.69; 95% CI: 0.54-0.88) followers.

Conclusion

The study culminates that women's autonomy in health decision making improves attitudes toward condom use during sex for HIV prevention in Ethiopia. Besides, women's higher education gets better wealth index, and HIV testing perks up the attitudes toward condom use; but religious affiliation deters it. Therefore, efforts need to be done in promoting women's autonomy along with empowering women in education, economic as well as HIV detection. Furthermore, designing interventions that address primary prevention strategies like using condoms consistently along with addressing religious affiliation can have a significant effect on curtailing HIV/AIDS scourge.

The effects of a cash transfer intervention on sexual partnerships and HIV in the HPTN 068 study in South Africa

Evidence on cash transfer interventions for HIV prevention in adolescent girls and young women is unclear and indicates that they may not work uniformly in all settings. Qualitative interviews were conducted with 22 girls and young women post-intervention to determine how a cash transfer study (HPTN 068) in South Africa was perceived to influence sexual behaviours and to explore mechanisms for these changes. Participants described how the intervention motivated them to increase condom use, have fewer partners, end risky relationships and access HIV testing services at local primary health clinics. Changes were attributed to receipt of the cash transfer, in addition to HIV testing and sexual health information. Processes of change included improved communication with partners and increased negotiation power in sexual decision-making. Economic empowerment interventions increase confidence in negotiating behaviours with sexual partners and are complementary to sexual health information and health services that provide young women with a foundation on which to make informed decisions about how to protect themselves.

HIV incidence among men who have sex with men and transgender women in four provinces in Thailand

The HIV epidemic in Thailand is concentrated in key populations, with the highest rates in men who have sex with men (MSM) and transgender women (TG). Previous studies of HIV incidence in these groups have been limited mostly to Bangkok. We measured HIV incidence in MSM and TG in four provinces and evaluated factors associated with incident infections to inform public health prevention efforts. An analysis was conducted using data collected during a prospective observational cohort study during April 2015-May 2018 in outpatient clinics in five hospitals across four provinces in Thailand. MSM and TG aged ≥18 years, who were not known to be HIV-infected, and who reported anal intercourse with a male or TG without a condom in the past six months were enrolled. Participants were followed-up every 6 months for 18 months with questionnaires and HIV testing. A total of 40 HIV seroconversions occurred during follow-up, resulting in an HIV incidence of 3.5 per 100 person-years (95% CI 2.5, 4.8). Multivariate analyses indicated that identifying as gay (adjusted hazard ratio [AHR] 4.9; 95% CI 1.7-14.2), having receptive anal sex in the past six months (AHR 3.6; 95% CI 1.4-9.5), using alcohol (AHR 3.3; 95% CI 1.3-8.3), and taking alkyl nitrites (AHR 4.4; 95% CI 1.7-11.2) in the past six months were all independently associated with HIV infection. Overall this study found a lower HIV incidence in the highest risk population in Thailand compared with similar studies in Bangkok. Accelerated prevention efforts are needed to make the goal of 'zero new infections' possible in Thailand.

The Evolution of HIV Prevention: From Discipline to Control

HIV prevention has changed since the identification of AIDS in 1981, the discovery of HIV in 1983, and the rollout of HIV antibody testing in 1985. Since this time, HIV prevention changed from behavior modification to testing to treatment as prevention to chemoprophylaxis using HIV medications among HIV-negative persons. While these modifications have been heralded as public health successes, critical evaluations are needed. In this article, we present one such review in which we argue that HIV prevention, while previously disciplinary in the Foucauldian sense, has become controlling in the Deleuzian sense. In this way, the parameters of context are targeted and behavior change is less relevant. This highlights the importance of questioning public health "advancements" and using novel theoretical lens to do so.

Patterns of Sexual Risk Behavior, HIV Infection, and Use of Health Services Among Sub-Saharan African Migrants in Portugal

This study identified patterns of sexual risk behavior among a sub-Saharan African migrant (SAM) population in Portugal and examined its associations with human immunodeficiency virus (HIV) prevalence, sociodemographics, use of sexual health services, and HIV testing. A cross-sectional biobehavioral survey was conducted with a venue-based sample of 790 SAMs. Data were collected using questionnaires and rapid HIV tests. Cluster analysis identified five subgroups with differing levels of HIV infection (2.5% to 11.3%). In Cluster 1, most participants reported sexual abstinence over the past year and the remaining used condoms consistently; this cluster had the highest HIV prevalence (11.3%). In Cluster 2, most reported one sexual partner and all reported unprotected sex; all HIV-positive participants in this cluster were unaware of their HIV-positive status. In Clusters 3 and 4, most had four or more partners, yet all used condoms. In Cluster 3, 56.5% reported both regular and occasional partners. In Cluster 4, 74% had only occasional partners; all engaged in commercial sex. In Cluster 5, all reported four or more partners and condomless sex. In all subgroups we found low rates of HIV testing and high unawareness of HIV serostatus. Targeted prevention interventions are needed to reduce unprotected sexual relations and undiagnosed infection, as well as improve linkage to sexual health services.
