This study explores the impact of alcohol use on PrEP initiation and continuation among South African men. We performed a secondary data analysis from a trial involving men aged 16-29, randomly selected in KwaZulu-Natal. Participants were referred to sexual health services, and those who were HIV negative and sexually active were offered oral PrEP. Alcohol consumption was categorized using AUDIT-C criteria as no/low risk (0-3) and hazardous alcohol use (4-12). Primary outcomes were PrEP initiation and continuation, defined as refilling prescriptions for ≥ 4 months. Logistic regression models adjusted for clinical and demographic confounders estimated relationships between PrEP initiation/continuation and alcohol use. Among 325 men analyzed, average age was 22.9 years (SD 3.6), with 146 (45%) reporting hazardous alcohol consumption. PrEP initiation was greatest among the hazardous/very-high risk group (40%), with the lowest uptake among men who do not use alcohol (17%). In multivariate analyses, those with hazardous alcohol use remained more likely to initiate PrEP compared to those with no/low risk alcohol use (aOR 1.96, 95%CI 1.13-3.40; p-value = 0.017). Only 27% (24/88) remained on PrEP at 4 months, with continuation similar between alcohol use groups (aOR 1.56, 95%CI: 0.47-5.12, p = 0.47). Hazardous alcohol use is prevalent among men in rural South Africa and associated with increased PrEP initiation. However, overall PrEP continuation was low and consistent across alcohol use levels. Hazardous alcohol use should not deter PrEP implementation efforts to engage young men.","PeriodicalId":7543,"journal":{"name":"AIDS and Behavior","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143787683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a critical need for a robust, reliable, and contemporary measure to identify populations at risk of avoiding HIV testing, treatment, and prevention, thereby supporting global HIV eradication goals. Focus groups informed the initial development of the HIV Anxiety Scale (HAS), revised through expert feedback. The factor structure was assessed in two studies. In Study 1, an Exploratory Factor Analysis (EFA) was conducted with 251 participants. In Study 2, a Confirmatory Factor Analysis (CFA) with 200 participants was performed alongside validity, internal consistency, and measurement invariance assessments. Studies 1 and 2 elicited a 3-factor model, resulting in a 16-item measure with the following subscales: Psychosocial Implications of HIV, Lifestyle Implications of HIV, and HIV Testing Anxiety. The HAS demonstrated a good factor structure, acceptable validity and excellent internal consistency across diverse groups in Study 2. The HAS provides a contemporary, robust measure of HIV anxiety, addressing limitations of previous tools and contributing to efforts to identify and support populations at risk of HIV avoidance behaviours. We recommend that future research continue to validate and test this new measure, but it offers a standardised tool to inform targeted interventions for HIV testing, prevention, and treatment.","PeriodicalId":7543,"journal":{"name":"AIDS and Behavior","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143787424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Voluntary Counselling and Testing points (VCTs) in Poland allow free and anonymous access to HIV testing among the adult population. The aim of the study was to investigate whether there is an increased occurrence of HIV infection among individuals who identify as homosexual and to profile three distinct groups among VCTs clients: the most common patient coming for testing, the most frequent HIV-positive individual, and the most typical Pre-Exposure Prophylaxis (PrEP) user. Data obtained from 29 VCT points in Poland between 2015 and 2023 were retrospectively analyzed. The prevalence of HIV infection in this cohort was calculated and a model for HIV infection risk among various populations was built. 295,556 patient reports revealed that heterosexual men aged 25-34 years (13.43%) tested most frequently. In total, the average prevalence of HIV-positive patients amounted to 1.36%. Among the tested population, HIV infection was the most prevalent among homosexual men aged 25-34 (0.34%). Moreover, we showed that the risk of receiving a positive HIV result was almost five times higher among homosexual and bisexual patients than among heterosexual individuals. The findings highlight the urgent need for targeted HIV prevention efforts, particularly among homosexual and bisexual men. Ongoing monitoring and education are necessary even among PrEP users to prevent new infections.","PeriodicalId":7543,"journal":{"name":"AIDS and Behavior","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143787686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was a stepped care randomized controlled trial. Sixty-eight YLH with established infection, without VS, and with at least two follow-ups (N = 68) were randomized to a control condition (n = 25) or a stepped care intervention (n = 43), and repeatedly assessed for up to 24 months. Both conditions received referrals for health services and a daily automated text-messaging and monitoring intervention (AMMI). YLH in stepped care who were unsuppressed at 4-month assessments stepped up to peer support and later to coaching. Random effects regressions examined VL trajectories over time as well as trajectories of secondary outcomes. There was significant evidence suggesting a different longitudinal trajectory of VLs for the two conditions. The control condition had improved VLs at about 12 months and then started to return to higher VLs. The stepped-care condition improved over the same time period and remained relatively stable. We estimated that the average VL was lower in the stepped care condition at 24 months, but we cannot claim a statistically significant difference between conditions. Both intervention groups appeared to have positive intervention impacts suggesting some benefits of the AMMI intervention. The improvement in VL at 24 months for stepped care compared to the control condition are suggestive of a viable intervention strategy that warrants further study.","PeriodicalId":7543,"journal":{"name":"AIDS and Behavior","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143787499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Think-aloud and Beta testing showed that users viewed the app positively and considered it to be user- friendly. Participants particularly liked the daily reminders and ability to communicate with peers with HIV and their HIV care team. Although most participants reported no dislikes, they requested more customization and more resources. The app achieved a high mean SUS score of 76 and high response rates for app features.

Blood donation centres employ comprehensive screening measures to identify donors with STIs, such as HIV, HBV, HCV, and syphilis, which can also transmitted through blood transfusions. Herein, we investigated the seroprevalence of STIs and demographic determinants related to multiple infections among rejected blood donors at the National Blood Transfusion Service (NBTS) in Angola. This was a cross-sectional study conducted with 1885 rejected blood donors serologically screened for anti-HBsAg, anti-HCV, anti-HIV, and anti-TP during pre-donation screening at the NBTS, located in Luanda, the capital city of Angola, between March 2022 to July 2023. Overall, HIV (11.2%), HBsAg (71.7%), HCV (9.30%), and Syphilis (8.80%) were detected. The multiple infection rate was 2.30%. HIV and syphilis were associated with age (p < 0.05). HBV was related to age, areas of residence, and occupation (p < 0.05). HCV was related to areas of residence and educational level (p < 0.05). No relationship was observed between demographic characteristics with multiple infections (p > 0.05). Individuals aged over 40 years (OR: 2.48, p = 0.393), males (OR: 1.33, p = 0.639), non-urbanized regions (OR: 1.18, p = 0.594), low educational level (OR: 3.46, p = 0.222), and employed (OR: 1.34, p = 0.423), were more likely to have multiple infections. Our results demonstrate a high rate of circulation of STIs among blood donation candidates in Luanda. HBV was the main reason for the rejection of candidates.
