Effect of peer health education intervention on HIV/AIDS knowledge amongst in-school adolescents in secondary schools in Imo State, Nigeria.

BACKGROUND: Peer education is an approach to health promotion in which community members are supported to promote health-enhancing change among their peers. The study assessed the effect of peer health education on HIV/AIDS knowledge amongst in-school adolescents in secondary schools in Imo State. METHODS: This was an intervention study carried out among 296 and 287 in-school adolescents aged 15 to 19 years attending Akwakuma Girls Secondary School and Federal Government Girls College Owerri Imo State respectively. The study was in three stages: before intervention, intervention, and after intervention. The impact of peer education was evaluated twelve weeks after intervention. Data were collected using semi-structured questionnaires. The study utilized a quasi-experimental study design. The chi-square test and McNemar's test were used to test the hypothesis with a significance level of p ≤ 0.05. RESULTS: The result from the study revealed that the majority (73%) of the respondents at Akwakuma Girls Secondary School (test group) had poor knowledge of HIV/AIDS mode of transmission and prevention at baseline. The overall good knowledge of respondents in the test group improved from 27 to 81% after the intervention. 36% of the respondents in the control group had good knowledge at baseline, the knowledge of 64% of them with poor knowledge at baseline were compared post-test to those in the test group who also had poor knowledge at baseline. The knowledge of only 27.7% of those in the control group increased post-test while the remaining 72.3% still had poor knowledge. The result of the inter-school comparison using Chi-square revealed that the p-value was statistically significant. Intra-school comparison using McNemar's test revealed a statistical significance for all questions in the test group, while none was positively significant in the control group. CONCLUSIONS: Peer health education improved the knowledge of the students at Akwakuma Girls Secondary School which was very low at the baseline. The knowledge of the students in the control group with poor knowledge at baseline didn't increase post-study. Peer health education should be strengthened and expanded as one of the tools for behavior change among adolescents. There should be more focus on adolescents for HIV-targeted prevention.

What may encourage or deter health services utilization by people living with or at the risk of HIV/AIDS in special health centers? Qualitative evidence from a stigmatized community.

BACKGROUND: Behavioral Diseases Counseling Centers (BDCCs) and Vulnerable Women's Counseling Centers (VWCCs) in Iran are the main peripheral centers that offer educational, counseling, diagnostic, preventive, curative and protective services to individuals living with or at high risk of contracting HIV/AIDS and female sex workers respectively. Due to the social stigma surrounding HIV in Iran, this study aims to identify the factors that may hinder or encourage HIV/AIDS patients and women with risky sexual behaviors from visiting these centers. METHODS: Conducted in 2023, this qualitative study involved individuals visiting BDCCs and VWCCs in two western provinces of Iran, Ilam and Kermanshah. The study participants included 21 health staff members working in BDCCs and VWCCs and 20 HIV/AIDS patients and vulnerable women with unsafe sexual behaviors referring to these centers. Purposive, snowball and maximum variation sampling techniques were applied to interview the participants. Interviews were conducted between January 5th and May 21st, 2023, using a semi-structure guideline. Interviews were transcribed and content analysis approach was applied to analyze data using MAXQDA20 software. RESULTS: According to the findings, the barriers and facilitators of visiting specialized centers for HIV/AIDS patients and vulnerable women were categorized into three main categories, 10 subcategories and 35 sub-subcategories including: Medical and operational processes (4 subcategories and 12 sub-subcategories), mutual interactions between the personnel and visitors (people living with and at the risk of getting HIV/AIDS) (3 subcategory and 13 sub-subcategories), and physical characteristics of the centers (3 subcategories and 10 sub-subcategories). CONCLUSIONS: To improve the performance of BDCCs and VWCCs and encourage people living with and at the risk of contracting HIV/AIDS to visit these centers regularly, health policy makers should consider modifying clinical processes, physical features, personnel behaviors and visitors' concerns raised by the interviewees and the issues identified in this study.

Knowledge, attitudes, and practices about HIV and other sexually transmitted infections among High School students in Southern Italy: A cross-sectional survey.

High School students, recognized as a high-risk group for sexually transmitted infections (STIs), were the focal point of an educational campaign in Southern Italy to share information and good practices about STIs and HIV/AIDS. A baseline survey comprising 76 items was conducted via the REDCap platform to assess students' initial knowledge, attitudes, and practices (KAP) related to STIs and HIV/AIDS. Sociodemographic variables were also investigated. The association between variables and KAP score was assessed by Kruskal-Wallis' or Spearman's test, as appropriate. An ordinal regression model was built to estimate the effect size, reported as odds ratio (OR) with a 95% confidence interval (CI), for achieving higher KAP scores among students features. On a scale of 0 to 29, 1702 participants achieved a median KAP score of 14 points. Higher scores were predominantly reported by students from classical High Schools (OR 3.19, 95% C.I. 1.60-6.33, p<0.001). Additionally, elevated scores were associated with sexually active students (OR 1.48, 95% C.I. 1.12-1.96, p = 0.01), those vaccinated against Human Papilloma Virus (OR 2.47, 95% C.I. 1.89-3.24, p<0.001), those who had used emergency contraception (OR 1.56, 95% C.I. 1.09-2.24, p = 0.02, Table 2) and those obtaining information from TikTok (OR 1.62, 95% C.I. 1.14-2.30, p = 0.01). Conversely, being heterosexual was associated with an overall lower score (OR 0.48, 95% C.I. 0.32-0.73, p<0.001). High School students, often due to early sexual debut, seek information about HIV and STIs independently using social channels. However, the overall level of knowledge, attitudes, and practices remains low. Urgent school-based interventions are needed for this age group.

Editorial: Forty Years of Waiting for Prevention and Cure of HIV Infection - Ongoing Challenges and Hopes for Vaccine Development and Overcoming Antiretroviral Drug Resistance.

In April 1984, 40 years ago, the Secretary of the US Department of Health and Human Services announced that Dr. Robert Gallo and his colleagues at the National Cancer Institute (NCI) had confirmed the cause of acquired immunodeficiency syndrome (AIDS) as a retrovirus, which became known as human immunodeficiency virus (HIV) in 1986. For the past 40 years, prevention and cure of HIV infection have been the dual 'holy grail' sought but still not achieved. By the beginning of 2024, the World Health Organization (WHO) estimated that in the past 40 years, between 65.0 million and 113.0 million people have been infected with HIV, and between 32.9 million and 51.3 million people have died from HIV infection. On 29 February 2024, the WHO published an updated report in response to increasing reports of HIV drug resistance (HIVDR). Currently, HIV vaccines in development are in early-stage clinical trials. People with HIV are more likely to develop tuberculosis, with increasing rates of antimicrobial resistance. MTBVAC is the first live attenuated vaccine to prevent Mycobacterium tuberculosis infection, with phase 2a safety and efficacy clinical trial data expected at the end of 2024. This editorial aims to summarize the current challenges and hopes for developing vaccines to prevent HIV infection and approaches to overcome antiretroviral drug resistance as a cure for HIV/AIDS.

Tuberculosis Preventive Treatment Update - U.S. President's Emergency Plan for AIDS Relief, 36 Countries, 2016-2023.

Tuberculosis (TB) is the leading cause of death among persons with HIV. In 2022, an estimated 167,000 TB-related deaths occurred globally among persons with HIV. TB preventive treatment (TPT) helps prevent TB disease and is recommended for persons at high risk for developing TB, including those with HIV. TPT, when taken with antiretroviral treatment (ART), can reduce TB-attributable deaths among persons with HIV. In 2018, the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) program committed to offer one course of TPT to all eligible clients receiving ART. This analysis describes trends in TPT initiation and completion among PEPFAR-supported programs in 36 countries in Africa, Central and South America, and Asia during fiscal years (FYs) 2017-2023. Overall, TPT initiation rates peaked in FY19, a possible sign of programmatic saturation. TPT initiation among clients who had been on ART <6 months reached 59%, and overall completion rates up to 87% were reported. Approximately 13 million persons with HIV have completed TPT since FY17, but widespread adoption of shorter regimens, patient-centered approaches, and electronic medical record systems might be needed to ensure full TPT coverage. Through PEPFAR's partnership with national HIV programs, TPT has become the standard of care for persons with HIV.

[High-risk sexual behaviors of HIV/AIDS and related factors in young students in Guangzhou].

Objective: To explore high-risk sexual behaviors of HIV/AIDS and related factors in young students in Guangzhou. Methods: A cross-sectional survey was conducted in 5 different types of Guangzhou colleges by convenience sampling with minimum number of classes per grade and 600 samples per school from September to November 2021. The R 4.2.2 software was used to consolidate databases. Simultaneously, a logistic regression model and a decision tree algorithm model, stratifying by whether sexual behaviors had occurred before, were constructed. In each layer, the prediction performance of the two models was evaluated through area under receiver operating characteristic and the confusion matrix, and then the model with high prediction performance was retained. Results: A total of 7 346 students were surveyed. The proportion of the respondents reporting sexual experience were 9.08% (667/7 346), in whom 26.24% (175/667) had risky sexual activity in the past year. The decision tree algorithm model performs well in predicting whether high-risk sexual behaviors have occurred in the past year. When the complexity parameter value is 0.018, and nsplit reaches 4, which means there are 5 leaf nodes in the model, the cross error of the tree will be the smallest. The first best grouping variable in the decision tree was whether to use condoms throughout the first sexual behavior. If condoms were used at their sexual debut, but homosexual practices have occurred in the past year, the probability of risky sexual behavior will increase. If homosexual practices have not occurred in the past year, but the age of sexual debut was below 18 years old while the period of HIV education was after high school, the probability of risk sexual behavior will also increase. Conclusions: AIDS-related risky behaviors of young students still deserved attention. The experience of sexual debut and whether AIDS-related health education has been received before the sexual debut were significant predictors for the occurrence of high-risk sexual behavior. The decision tree algorithm model has particular applicability for predicting and screening potential risk populations.

The global burden of HIV.

The global burden of HIV remains a formidable challenge, affecting millions. Despite significant progress in understanding, treatment, and prevention , HIV/AIDS continues to exert a substantial impact on personal and public health, particularly in sub-Saharan Africa, where the prevalence is highest. HIV not only poses a direct threat to the well-being of individuals but also contributes to social and economic disparities. Approximately 38 million people worldwide are living with HIV, with millions unaware of their status. Stigma and discrimination still hinder testing, starting and staying on treatment. Access to antiretroviral therapy has improved, yet disparities persist, with marginalized communities often facing barriers to essential health care services. Efforts to reduce new HIV infections and transmission include comprehensive prevention strategies, education, and increased access to testing and treatment. Addressing social determinants, reducing stigma, and ensuring equitable access to health care remain crucial to reach the ambitious goal of ending AIDS by 2030.

Chapitre 3. Inégalités dans le dépistage et la prévention du VIH/SIDA.

Despite progress in the detection and treatment of the Human Immunodeficiency Virus (HIV), major challenges remain in developing countries due to insufficient resources and infrastructure. The number of people living with HIV who do not know their serostatus has fallen worldwide. However, a number of existing obstacles stand in the way of better results. The socio-cultural context in Africa hampers knowledge and understanding of the disease, leading to stigmatizing attitudes, reluctance to undergo screening and poor access to treatment.Inequalities also exist within the countries of the North, as in the case of the French West Indies, which benefit from a policy to combat HIV/AIDS, with results that fall short of those in mainland France. For this reason, we have chosen to compare the situation in the West Indies with that in Benin, in the context of African culture.Our analysis takes stock of the issues and prospects linked to the accessibility and use of screening care in sub-Saharan Africa and the French Departments of America (DFA).In both cases, fear of the disease, stigmatization, fear of a positive HIV test result and fear of disclosing the test result limit preventive and treatment actions for an effective fight against HIV.In sub-Saharan Africa, women are more likely to accept a screening test than men. Certain populations, including adolescents and homosexuals, are in a vulnerable position. The comparison reveals similar attitudes and suggests actions or recommendations in both countries that have produced results.Innovative strategies and specific programs must be implemented to turn the tide in the fight against the HIV epidemic.

Looking back to see forward: multidirectional learning between the US Ryan White HIV/AIDS Program and the US President's Emergency Plan for AIDS Relief.

To end the HIV epidemic as a public health threat, there is urgent need to increase the frequency, depth and intentionality of bidirectional and mutually beneficial collaboration and coordination between the USA and global HIV/AIDS response. The US Health Resources and Services Administration (HRSA) is uniquely positioned to showcase bidirectional learning between high-income and low-income and middle-income countries (LMICs) in the fight against HIV. For 30 years, HRSA has successfully administered the Ryan White HIV/AIDS Program (RWHAP), the largest federal programme designed specifically for people with HIV in the USA. Further, HRSA has developed and delivered innovative, cost-effective, impactful HIV programmes in over 30 countries as an implementing agency for the US President's Emergency Plan for AIDS Relief (PEPFAR). When PEPFAR was authorised in 2003, HRSA rapidly developed systems and infrastructures to deliver life-saving treatment, initiated workforce development programmes to mitigate health worker shortages, and laid the path for transitioning PEPFAR activities from US-based organisations to sustainable, country-led entities. As global programmes matured, lessons learnt within LMICs gradually began strengthening health services in the USA. To fully optimise synergies between RWHAP and PEPFAR, there is a critical need to build on successful initiatives, harness innovation and technology, and inculcate the spirt of multidirectional learning into global health. HRSA is promoting bidirectional learning between domestic and international HIV programming through documenting, sharing and implementing strategies, lessons learnt, best practices and effective models of care to accelerate achievement of HIV epidemic control and support country-led, sustained responses to public health threats.

Income determines the impact of cash transfers on HIV/AIDS: cohort study of 22.7 million Brazilians.

Living with extremely low-income is an important risk factor for HIV/AIDS and can be mitigated by conditional cash transfers. Using a cohort of 22.7 million low-income individuals during 9 years, we evaluated the effects of the world's largest conditional cash transfer, the Programa Bolsa Família, on HIV/AIDS-related outcomes. Exposure to Programa Bolsa Família was associated with reduced AIDS incidence by 41% (RR:0.59; 95%CI:0.57-0.61), mortality by 39% (RR:0.61; 95%CI:0.57-0.64), and case fatality rates by 25% (RR:0.75; 95%CI:0.66-0.85) in the cohort, and Programa Bolsa Família effects were considerably stronger among individuals of extremely low-income [reduction of 55% for incidence (RR:0.45, 95% CI:0.42-0.47), 54% mortality (RR:0.46, 95% CI:0.42-0.49), and 37% case-fatality (RR:0.63, 95% CI:0.51 -0.76)], decreasing gradually until having no effect in individuals with higher incomes. Similar effects were observed on HIV notification. Programa Bolsa Família impact was also stronger among women and adolescents. Several sensitivity and triangulation analyses demonstrated the robustness of the results. Conditional cash transfers can significantly reduce AIDS morbidity and mortality in extremely vulnerable populations and should be considered an essential intervention to achieve AIDS-related sustainable development goals by 2030.

'Ending AIDS' between comparison and commensuration and the role of global health indicators.

The use of targets and indicators in global health has become ubiquitous within global health and disease elimination programmes. The drive to 'end AIDS' has become a global flagship endeavour, including nation-states, donor organisations, NGOs, pharmaceutical companies, medical researchers, and activists. Almost synonymous with the campaign of ending AIDS is UNAIDS' 90-90-90 targets. Beyond indicators' role in neoliberal global health, an essential aspect of indicators and quantitative metrics is their ability to provide a basis for measurements and comparability across time and between different actors and entities. These processes are based on what has been called, commensuration, visual simplification, and serialisation. This article seeks to provide an account of how we can think about indicators in the drive to end AIDS as doing work that is contingent upon commensuration, simplification, and serialisation. The argument is that by attending to issues of commensuration, visual simplification, and serialisation we are better able to see how we risk erasing and foreclosing other forms of conceptualising what the end of AIDS could be. Logics of quantification risks erasing and foreclosing other qualitative aspects of the HIV epidemic as well as obscuring various epistemological tensions inherent in counting towards the end of AIDS.

Reshaping the narrative: Tracing the historical trajectory of HIV/AIDS, gay men, and public health in Sweden.

The human immunodeficiency virus (HIV) emerged as an endemic health crisis in the United States during the early 1980s. Initially labelled a "gay disease" due to its prevalence among gay men, the spread of HIV led to widespread fear and moral panic, as there was limited medical knowledge on preventing its transmission. While HIV is often associated with Sub-Saharan Africa, this article focuses on Sweden, a pioneering nation that became the first to achieve the remarkable Joint UNAIDS/WHO 90-90-90 continuum in addressing the epidemic. However, despite this significant milestone, the punitive legislation and attitudes prevalent in Sweden have had a counterproductive effect on curbing the virus's spread. Drawing upon a comprehensive triangulation of various data and sources on the evolution of public policy in Sweden, this article argues for the urgent need to reduce stigma surrounding HIV and AIDS. By undertaking further measures to combat stigmatisation, we not only have the potential to prevent the spread of HIV but also significantly enhance the quality of life for individuals living with the virus. An essential step in this journey is to eliminate the legally-enforced mandatory disclosure of one's HIV status, which would mark a tremendous victory for all those affected. With limited evidence to support the effectiveness of criminalisation and penal laws, no longer being viewed as criminals for non-disclosure would be a monumental achievement, positively transforming the lives of people living with HIV and fostering a more inclusive and supportive society.

Updated Data and Methods for the 2023 UNAIDS HIV Estimates.

ABSTRACT: Each year, supported by the Joint United Nations Programme on HIV/AIDS (UNAIDS), country teams across the globe produce estimates that chart the state of their HIV epidemics. In 2023, HIV estimates were available for 174 countries, accounting for 99% of the global population, of which teams from 150 countries actively engaged in this process. The methods used to derive these estimates are developed under the guidance of the UNAIDS Reference Group on Estimates, Modeling, and Projections (www.epidem.org). Updates to these methods and epidemiological analyses that inform parameters and assumptions are documented in this supplement.

The City Clinic Cohort Study: Hepatitis B, HTLV-III/LAV, and CDC AIDS Project 24.

Anticipating the availability of a safe vaccine, scientists at the Center for Disease Control (CDC) planned for a multicenter study of the prevalence, incidence, and efficacy of an experimental vaccine for hepatitis B in 1977, conducted the study among homosexual male volunteers in five collaborating sexually transmitted infection (STI) clinics in the United States from April 1978 through 1980, and concluded that the candidate vaccine was highly efficacious in preventing infections with the hepatitis B virus. Then something completely unexpected and portentous happened. Some successfully vaccinated as well as other homosexual and bisexual men began to show signs and symptoms of a rare cancer, Kaposi's sarcoma, and opportunistic infections typically associated with severe immunodeficiency. As early as October 1983, members of the Hepatitis B study cohort in San Francisco were invited to return to the city STI clinic for further examinations, testing, and confidential interviews about their sexual and other practices. CDC AIDS Project 24 was designed to help describe the natural history of AIDS, define risk factors, and predict future trends. It produced some of the earliest and most convincing scientific evidence about the seriousness and extent of the AIDS epidemic among homosexual and bisexual men in the United States. How the City Clinic Cohort Study came about and evolved is the focus of this commentary.

RESUMEN: Anticipando la disponibilidad de una vacuna segura, los científicos del Centro para el Control de Enfermedades (CDC) planearon un estudio multicéntrico sobre la prevalencia, incidencia y eficacia de una vacuna experimental contra la hepatitis B en 1977; realizaron el estudio entre voluntarios varones homosexuales en cinco colaboraron con clínicas de infecciones de transmisión sexual (ITS) en los Estados Unidos desde abril de 1978 hasta 1980, y concluyeron que la vacuna candidata era muy eficaz para prevenir infecciones por el virus de la hepatitis B. Entonces sucedió algo completamente inesperado y portentoso. Algunos hombres vacunados con éxito, así como otros hombres homosexuales y bisexuales, comenzaron a mostrar signos y síntomas de un cáncer poco común, el sarcoma de Kaposi, e infecciones oportunistas típicamente asociadas con una inmunodeficiencia grave. Ya en octubre de 1983, se invitó a los miembros de la cohorte del estudio de la hepatitis B en San Francisco a regresar a la clínica de ITS de la ciudad para realizar más exámenes, pruebas y entrevistas confidenciales sobre sus prácticas sexuales y de otro tipo. El Proyecto 24 del CDC sobre SIDA fue diseñado para ayudar a describir la historia natural del SIDA, definir factores de riesgo y predecir tendencias futuras. Produjo algunas de las primeras y más convincentes pruebas científicas sobre la gravedad y el alcance de la epidemia de SIDA entre los hombres homosexuales y bisexuales en los Estados Unidos. El tema central de este comentario es cómo surgió y evolucionó el estudio de cohorte de City Clinic.

Decision-Making for HIV AIDS Prevention: Altruism and the Moral Norm.

The purpose of this enquiry was to understand how gay men form and maintain their attitudes toward HIV transmission preventative behaviors. Autobiographical life histories of sixteen gay men showed that once they acquired knowledge of preventative behavior they consistently adhered to that behavior. They adhered because of fear of HIV infection and because they held a moral norm that obligated them to behave altruistically (Schwartz, 1977) to protect not only themselves, but also their sex partners, loved ones, and their positive self-evaluation. They saw their HIV negative status, and their adherence, as pre-requisite and enabler for achieving their goals in life. Dick and Basu's (1994) Framework for Customer Loyalty, a commercial marketing communications theoretical framework, explains development and maintenance of these men's loyalty (their consistent adherence). This understanding, within a marketing communications framework, will inform development of social marketing communications aiming to increase adherence to behaviors that prevent HIV transmission.
