Digital interventions for STI and HIV partner notification: a scoping review.

BACKGROUND: Partner notification (PN) is key to the control of sexually transmitted infections (STIs) and human immunodeficiency virus (HIV). Digital interventions have been used to facilitate PN. A scoping review was conducted to describe the interventions used, user preferences and acceptability of digital PN interventions from patient and partner perspectives. METHODS: A systematic literature search was conducted of eight databases for articles published in English, available online with digital PN outcome data. Articles were assessed using the Mixed Methods Appraisal Tool. Quantitative and qualitative data were synthesised and analysed using thematic analysis. RESULTS: Twenty-six articles met the eligibility criteria. Articles were heterogeneous in quality and design, with the majority using quantitative methods. Nine articles focused solely on bacterial STIs (five on syphilis; four on chlamydia), one on HIV, two on syphilis and HIV, and 14 included multiple STIs, of which 13 included HIV. There has been a shift over time from digital PN interventions solely focusing on notifying partners, to interventions including elements of partner management, such as facilitation of partner testing and treatment, or sharing of STI test results (between index patients and tested sex partners). Main outcomes measured were number of partners notified (13 articles), partner testing/consultation (eight articles) and treatment (five articles). Relationship type and STI type appeared to affect digital PN preferences for index patients with digital methods preferred for casual rather than established partner types. Generally, partners preferred face-to-face PN. CONCLUSION: Digital PN to date mainly focuses on notifying partners rather than comprehensive partner management. Despite an overall preference for face-to-face PN with partners, digital PN could play a useful role in improving outcomes for certain partner types and infections. Further research needs to understand the impact of digital PN interventions on specific PN outcomes, their effectiveness for different infections and include health economic evaluations.

Social marketing and mass media interventions to increase sexually transmissible infections (STIs) testing among young people: social marketing and visual design component analysis.

INTRODUCTION: Globally, sexually transmissible infections (STIs) continue to disproportionately affect young people. Regular STI testing is an important public health strategy but remains low among this age group. Raising awareness of testing is an essential step and requires effective interventions designed for young people. To inform the development of effective interventions that promote STI testing among young people, we conducted a systematic literature review to describe the social marketing and visual design components commonly found in STI testing interventions and explore associations of these components with intervention effectiveness. METHODS: We used a systemic review methodology to identify peer-reviewed articles that met pre-defined inclusion criteria. Social marketing and visual component analyses were conducted using structured data extraction tools and coding schemes, based on the eight key social marketing principles and 28 descriptive dimensions for visual analysis. RESULTS: 18 studies focusing on 13 separate interventions met the inclusion criteria. Most interventions used photograph-based images, using conventionally attractive actors, positioned centrally and making direct eye contact to engage the viewer. The majority of interventions featured text sparingly and drew on a range of tones (e.g. serious, humorous, positive, reassuring, empowering and informative) and three interventions used sexualised content. Four articles explicitly stated that the interventions was informed by social marketing principles, with two explicitly referencing all eight principles. Around half of the articles reported using a formal theoretical framework, but most were considered to have theoretical constructs implicit in interventions materials. Four articles provided detailed information regarding developmental consumer research or pre-testing. All articles suggested segmentation and development of materials specifically for young people. Explicit consideration of motivation and competition was lacking across all articles. This study found that there were some design elements common to interventions which were considered more effective. High social marketing complexity (where interventions met at least seven of the 11 criteria for complexity) seemed to be associated with more effective interventions. CONCLUSIONS: Our findings suggest that the incorporation of social marketing principles, could be more important for intervention effectiveness than specific elements of visual design. Effective and systematic use of social marketing principles may help to inform future evidence-informed and theoretically based interventions and should be employed within sexual health improvement efforts.

Improving digital partner notification for sexually transmitted infections and HIV through a systematic review and application of the Behaviour Change Wheel approach.

BACKGROUND: Partner notification (PN) is key to controlling sexually transmitted infections (STIs) and human immunodeficiency virus (HIV). Digital PN options (e.g. social media, short message service (SMS), emails) are promising in increasing PN behaviour. However, their implementation is often challenging and studies report varied levels of acceptability and uptake of PN, highlighting the need to optimise digital PN interventions. METHODS: A systematic review of barriers and facilitators to digital PN interventions for STIs, including HIV, across eight research databases (from 2010 to 2023) identified eight relevant studies, two of which addressed HIV. Data extraction identified 98 barriers and 54 facilitators to the use of digital PN interventions. These were synthesised into 18 key barriers and 17 key facilitators that were each deemed amenable to change. We then used the Behaviour Change Wheel approach, the Acceptability, Practicability, Effectiveness, Affordability, Side-effects and Equity criteria, and multidisciplinary expert input, to systematically develop practical recommendations to optimise digital PN. RESULTS: Thirty-two specific recommendations clustered around three themes. Digital PN interventions should: (1) empower and support the index patient by providing a range of notification options, accompanied by clear instructions; (2) integrate into users' existing habits and the digital landscape, meeting contemporary standards and expectations of usability; and (3) address the social context of PN both online and offline through normalising the act of PN, combating STI-related stigma and stressing the altruistic aspects of PN through consistent messaging to service users and the public. CONCLUSIONS: Our evidence-based recommendations should be used to optimise existing digital PN interventions and inform the co-production of new ones.

Improving HIV pre-exposure prophylaxis (PrEP) uptake and initiation: process evaluation and recommendation development from a national PrEP program†.

BACKGROUND: HIV pre-exposure prophylaxis (PrEP) is key to HIV transmission elimination but implementation is challenging and under-researched. We undertook a process evaluation of the first 2years of a national PrEP program to explore barriers and facilitators to implementation and to develop recommendations to improve implementation, focusing on PrEP uptake and initiation. METHODS: Stage 1 involved semi-structured telephone interviews and focus groups (September 2018-July 2019) with geographically and demographically diverse patients seeking/using/declining/stopping PrEP (n =39), sexual healthcare professionals (n =54), community-based organisation service users (n =9) and staff (n =15) across Scotland. We used deductive thematic analysis, to derive and then map key barriers and facilitators to priority areas that experts agreed would enhance uptake and initiation. In Stage 2, we used analytic tools from implementation science to systematically generate evidence-based, theoretically-informed recommendations to enhance uptake and initiation of PrEP. RESULTS: Barriers and facilitators were multi-levelled and interdependent. Barriers included the rapid pace of implementation without additional resource, and a lack of familiarity with PrEP prescribing. Facilitators included opportunities for acquisition of practice-based knowledge and normalisation of initiation activities. We refined our 68 'long-list' recommendations to 41 using expert input and the APEASE (Acceptability, Practicability, Effectiveness, Affordability, Side-effects, and Equity) criteria. Examples include: provision of PrEP in diverse settings to reach all in need; co-produced, culturally sensitive training resources for healthcare professionals, with focused content on non-daily dosing; meaningful collaborative working across all stakeholders. CONCLUSIONS: These evidence-based, theory informed recommendations provide a robust framework for optimising PrEP uptake and initiation in diverse settings to ensure PrEP reaches all who may benefit.

Frontline experiences of delivering remote mental health supports during the COVID-19 pandemic in Scotland: innovations, insights and lessons learned from mental health workers.

COVID-19 restrictions drove rapid adaptations to service delivery and new ways of working within Scotland's mental health sector. This study explores mental health workers' (MHWs') experiences of delivering their services remotely. Twenty participants, who had worked in mental health professions in the National Health Service (NHS) in Scotland throughout the COVID-19 pandemic, took part in online semi-structured interviews. Data was transcribed then analysed using an inductive thematic analysis. Two major themes are reported: (1) 'Improved Flexibility for both MHWs and Service Users' and (2) 'Teletherapies Challenge Therapeutic Boundaries'. In relation to (1) virtual platforms were seen as vital in maintaining patient care throughout the COVID-19 pandemic and a valuable resource for service users (SUs) who had previously struggled with mobility or social anxieties when accessing face-to-face services. Some MHWs' also noted benefits for their productivity and comfort. Regarding (2) MHWs highlighted that whilst conducting teletherapies from home, work-life boundaries became blurred and, in some instances, typically comforting spaces became associated with the traumatic content discussed by SUs. These stressors seemed to be compounded by MHWs' isolation, as they were less able to draw upon their colleagues for support. Further, confidentiality could not be assured, as MHWs and SUs alike had to accommodate their family members. These findings highlight important insights from MHWs in adapting to rapid changes in mental health working practices, particularly in relation to the challenges of delivering quality, safe and equitable services and the increased use of teletherapies. Such insights are vital in informing service developments and supporting future pandemic preparedness across a range of healthcare contexts and countries seeking to adopt hybrid models of mental health service delivery.

Going beyond 'regular and casual': development of a classification of sexual partner types to enhance partner notification for STIs.

OBJECTIVES: To develop a classification of sexual partner types for use in partner notification (PN) for STIs. METHODS: A four-step process: (1) an iterative synthesis of five sources of evidence: scoping review of social and health sciences literature on partner types; analysis of relationship types in dating apps; systematic review of PN intervention content; and review of PN guidelines; qualitative interviews with public, patients and health professionals to generate an initial comprehensive classification; (2) multidisciplinary clinical expert consultation to revise the classification; (3) piloting of the revised classification in sexual health clinics during a randomised controlled trial of PN; (4) application of the Theoretical Domains Framework (TDF) to identify index patients' willingness to engage in PN for each partner type. RESULTS: Five main partner types emerged from the evidence synthesis and consultation: 'established partner', 'new partner', 'occasional partner', 'one-off partner' and 'sex worker'. The types differed across several dimensions, including likely perceptions of sexual exclusivity, likelihood of sex reoccurring between index patient and sex partner. Sexual health professionals found the classification easy to operationalise. During the trial, they assigned all 3288 partners described by 2223 index patients to a category. The TDF analysis suggested that the partner types might be associated with different risks of STI reinfection, onward transmission and index patients' engagement with PN. CONCLUSIONS: We developed an evidence-informed, useable classification of five sexual partner types to underpin PN practice and other STI prevention interventions. Analysis of biomedical, psychological and social factors that distinguish different partner types shows how each could warrant a tailored PN approach. This classification could facilitate the use of partner-centred outcomes. Additional studies are needed to determine the utility of the classification to improve measurement of the impact of PN strategies and help focus resources.

Association of perceived job security and chronic health conditions with retirement in older UK and US workers.

BACKGROUND: The relationship between job insecurity, chronic health conditions (CHCs) and retirement among older workers are likely to differ between countries that have different labor markets and health and social safety nets. To date, there are no epidemiological studies that have prospectively assessed the role of job insecurity in retirement incidence, while accounting for CHC trajectories in two countries with different welfare systems. We investigated the strength of the association between baseline job insecurity and retirement incidence over an 11-year period while accounting for CHC trajectories, among workers 50-55 years of age at baseline in the UK and USA. METHODS: We performed Cox proportional hazards regression analysis, using 2006-2016 data from the Health and Retirement Study (US cohort, n = 570) and English Longitudinal Study on Aging (UK cohort n = 1052). RESULTS: Job insecurity was associated with retirement after adjusting for CHC trajectories (HR = 0.69, 95% CI = 0.50-0.95) in the UK cohort only. CHC trajectories were associated with retirement in both cohorts; however, this association was attenuated in the US cohort, but remained significant for the medium-increasing trajectory in the UK cohort (HR = 1.41, 95% CI = 1.01-1.97) after adjustment for all covariates. Full adjustment for relevant covariates attenuated the association between job insecurity and retirement indicating that CHCs, social and health factors are contributing mechanistic factors underpinning retirement incidence. CONCLUSIONS: The observed differences in the two cohorts may be driven by macro-level factors operating latently, which may affect the work environment, health outcomes and retirement decisions uniquely in different settings.

COVID-19 vaccine hesitancy among health and social care workers during mass vaccination in Scotland.

Health and social care workers (HSCWs) have an essential role in the uptake of the COVID-19 vaccine. Vaccination is an emotionally charged issue and perceptions of risk associated with COVID19 can contribute towards vaccine hesitancy (VH). The aim of this study was to explore the role of emotion and risk perception associated with HSCWs' uptake of the COVID-19 vaccine during the initial mass roll-out of the vaccine in Scotland. A cross-sectional online survey with a correlational design was used. An online survey was conducted with HSCWs (N = 1189) aged 18 to 67 years (M = 44.09 yrs, SD = 11.48) working in Scotland during the third lockdown period (26 December - 31 March 2021) of the COVID-19 pandemic. The survey collected data relating to sociodemographic characteristics, vaccine uptake and VH, emotions associated with the COVID-19 vaccine, and risk perception. Open-ended free text data were also collected on HSCWs' main reasons for VH. Most participants (83.96%) felt positively about the roll-out of the COVID-19 vaccine, stating it would be beneficial for themselves and others to receive it. Nonetheless, 16.04% of HSCWs expressed VH. Occupational group, age, gender and risk perceptions did not affect variance in VH, but positive emotions associated with the COVID-19 vaccine and years of experience did. We emphasise the importance of future interventions to increase COVID-19 vaccine uptake by enhancing positive emotions and reducing ambivalent emotions associated with the COVID-19 vaccine particularly among less experienced HSCWs.

Provider-related barriers and enablers to the provision of hepatitis C treatment by general practitioners in Scotland: A behaviour change analysis.

The ease of direct-acting antiviral (DAA) medications for hepatitis C virus (HCV) has provided an opportunity to decentralize HCV treatment into community settings. However, the role of non-specialist clinicians in community-based pathways has received scant attention to date. This study examined barriers and enablers to expanding the role of general practitioners (GPs) in HCV treatment provision, using simple behaviour change theory as a conceptual framework. A maximum variation sample of 22 HCV treatment providers, GPs and HCV support workers participated in semi-structured interviews. Data were inductively coded, and the resulting codes deductively mapped into three principal components of behaviour change: capability, opportunity and motivation (COM-B). By this process, a number of provider- and systemic-level barriers and enablers were identified. Key barriers included the pre-treatment assessment of liver fibrosis, GP capacity and the 'speciality' of HCV care. Enablers included the simplicity of the drugs, existing GP/patient relationships and the provision of holistic care. In addition to these specific factors, the data also exposed an overarching provider understanding of 'HCV treatment' as triumvirate in nature, incorporating the assessment of liver fibrosis, the provision of holistic support and the treatment of disease. This understanding imposes a further fundamental barrier to GP-led treatment as each of these three components needs to be individually addressed. To enable sustainable models of HCV treatment provision by GPs, a pragmatic re-examination of the 'HCV treatment triumvirate' is required, and a paradigm shift from the 'refer and treat' status quo.

How can we make self-sampling packs for sexually transmitted infections and bloodborne viruses more inclusive? A qualitative study with people with mild learning disabilities and low health literacy.

OBJECTIVES: 1.5 million people in the UK have mild to moderate learning disabilities. STIs and bloodborne viruses (BBVs) are over-represented in people experiencing broader health inequalities, which include those with mild learning disabilities. Self-managed care, including self-sampling for STIs/BBVs, is increasingly commonplace, requiring agency and health literacy. To inform the development of a partner notification trial, we explored barriers and facilitators to correct use of an STI/BBV self-sampling pack among people with mild learning disabilities. METHODS: Using purposive and convenience sampling we conducted four interviews and five gender-specific focus groups with 25 people (13 women, 12 men) with mild learning disabilities (July-August 2018) in Scotland. We balanced deductive and inductive thematic analyses of audio transcripts to explore issues associated with barriers and facilitators to correct use of the pack. RESULTS: All participants found at least one element of the pack challenging or impossible, but welcomed the opportunity to undertake sexual health screening without attending a clinic and welcomed the inclusion of condoms. Reported barriers to correct use included perceived overly complex STI/BBV information and instructions, feeling overwhelmed and the manual dexterity required for blood sampling. Many women struggled interpreting anatomical diagrams depicting vulvovaginal self-swabbing. Facilitators included pre-existing STI/BBV knowledge, familiarity with self-management, good social support and knowing that the service afforded privacy. CONCLUSION: In the first study to explore the usability of self-sampling packs for STI/BBV in people with learning disabilities, participants found it challenging to use the pack. Limiting information to the minimum required to inform decision-making, 'easy read' formats, simple language, large font sizes and simpler diagrams could improve acceptability. However, some people will remain unable to engage with self-sampling at all. To avoid widening health inequalities, face-to-face options should continue to be provided for those unable or unwilling to engage with self-managed care.

Validation of a Clinical Prediction Rule to Predict Asymptomatic Chlamydia and Gonorrhea Infections Among Internet-Based Testers.

BACKGROUND: Clinical prediction rules (CPRs) can be used in sexually transmitted infection (STI) testing environments to prioritize individuals at the highest risk of infection and optimize resource allocation. We previously derived a CPR to predict asymptomatic chlamydia and/or gonorrhea (CT/NG) infection among women and heterosexual men at in-person STI clinics based on 5 predictors. Population differences between clinic-based and Internet-based testers may limit the tool's application across settings. The primary objective of this study was to assess the validity, sensitivity, and overall performance of this CPR within an Internet-based testing environment (GetCheckedOnline.com). METHODS: We analyzed GetCheckedOnline online risk assessment and laboratory data from October 2015 to June 2019. We compared the STI clinic population used for CPR derivation (data previously published) and the GetCheckedOnline validation population using χ2 tests. Calibration and discrimination were assessed using the Hosmer-Lemeshow goodness-of-fit test and the area under the receiver operating curve, respectively. Sensitivity and the fraction of total screening tests offered were quantified for CPR-predicted risk scores. RESULTS: Asymptomatic CT/NG infection prevalence in the GetCheckedOnline population (n = 5478) was higher than in the STI clinic population (n = 10,437; 2.4% vs. 1.8%, P = 0.007). When applied to GetCheckedOnline, the CPR had reasonable calibration (Hosmer-Lemeshow, P = 0.90) and discrimination (area under the receiver operating characteristic, 0.64). By screening only individuals with total risk scores ≥4, we would detect 97% of infections and reduce screening by 14%. CONCLUSIONS: The application of an existing CPR to detect asymptomatic CT/NG infection is valid within an Internet-based STI testing environment. Clinical prediction rules applied online can reduce unnecessary STI testing and optimize resource allocation within publicly funded health systems.

Mental health, potential minority stressors and resilience: evidence from a cross-sectional survey of gay, bisexual and other men who have sex with men within the Celtic nations.

BACKGROUND: Gay, bisexual and other men who have sex with men (GBMSM) are at a greater risk of mental health problems, such as anxiety and depression, than heterosexual adults. Numerous factors and stressors have been reported to impact men's mental health, although it has been suggested that resilience could have a protective effect. The aim of this study is to explore mental health, minority stressors, and resilience among a large online cross-sectional survey of GBMSM in the Celtic nations. METHODS: Data for this cross-sectional study were collected from the Social Media, GBMSM and Sexual and Holistic Health (SMMASH2) self-report online survey. Participants (n = 3077) were recruited via gay sociosexual media in Scotland, Wales, Northern Ireland, and the Republic of Ireland. Binary logistic regression analyses were conducted to identify factors that increased the odds of moderate-to-severe anxiety and depression. Potentially relevant variables (p < 0.05) were carried forward in hierarchal logistic regression analyses. RESULTS: The prevalence of moderate-to-severe anxiety and depression was 19.9 and 14.4%, respectively. Having a disability (OR = 1.73) and having financial worries sometimes/all of the time (OR = 1.93) increased the odds of having moderate-to-severe depression and anxiety, respectively. No minority stressors were associated with depression, whereas experiencing any form of relationship abuse in the last 12 months significantly increased the odds of anxiety (OR = 1.50). Resilience, namely a sense of coherence, had a protective effect and significantly reduced the odds of moderate-to-severe depression (OR = 0.85) and anxiety (OR = 0.89). CONCLUSIONS: Disability and financial worries were associated with increased depression and anxiety, respectively, while resilience had a protective effect for GBMSM in the SMMASH2 study. Future research is needed to better understand the role of resilience and the challenges and stresses of everyday life and intersecting health problems. Future research is also needed that incorporates the perspectives of those most affected by mental ill-health to co-develop effective solutions that respond to their contextual surroundings.

Sexual health literacy among gay, bisexual and other men who have sex with men: a conceptual framework for future research.

Good sexual health requires navigating intimate relationships within diverse power dynamics and sexual cultures, coupled with the complexities of increasing biomedicalisation of sexual health. Understanding this is important for the implementation of biomedical HIV prevention. We propose a socially nuanced conceptual framework for sexual health literacy developed through a consensus building workshop with experts in the field. We use rigorous qualitative data analysis to illustrate the functionality of the framework by reference to two complementary studies. The first collected data from five focus groups (FGs) in 2012 (n = 22), with gay, bisexual and other men who have sex with men aged 18-75 years and 20 in-depth interviews in 2013 with men aged 19-60 years. The second included 12 FGs in 2014/15 with 55 patients/service providers involved in the use/implementation of HIV self-testing or HIV prevention/care. Sexual health literacy goes well beyond individual health literacy and is enabled through complex community practices and multi-sectoral services. It is affected by emerging (and older) technologies and demands tailored approaches for specific groups and needs. The framework serves as a starting point for how sexual health literacy should be understood in the evaluation of sustainable and equitable implementation of biomedical sexual healthcare and prevention internationally.

Risk perception, safer sex practices and PrEP enthusiasm: barriers and facilitators to oral HIV pre-exposure prophylaxis in Black African and Black Caribbean women in the UK.

OBJECTIVES: UK Black African/Black Caribbean women remain disproportionately affected by HIV. Although oral pre-exposure prophylaxis (PrEP) could offer them an effective HIV prevention method, uptake remains limited. This study examined barriers and facilitators to PrEP awareness and candidacy perceptions for Black African/Black Caribbean women to help inform PrEP programmes and service development. METHODS: Using purposive sampling through community organisations, 32 in-depth, semi-structured interviews were conducted with Black African/Black Caribbean women living in London and Glasgow between June and August 2018. Participants (aged 19-63) included women of varied HIV statuses to explore perceptions of sexual risk and safer sex, sexual health knowledge and PrEP attitudes. A thematic analysis guided by the Social Ecological Model was used to explore how PrEP perceptions intersected with wider safer sex understandings and practices. RESULTS: Four key levels of influence shaping safer sex notions and PrEP candidacy perceptions emerged: personal, interpersonal, perceived environment and policy. PrEP-specific knowledge was low and some expressed distrust in PrEP. Many women were enthusiastic about PrEP for others but did not situate PrEP within their own safer sex understandings, sometimes due to difficulty assessing their own HIV risk. Many felt that PrEP could undermine intimacy in their relationships by disrupting the shared responsibility implicit within other HIV prevention methods. Women described extensive interpersonal networks that supported their sexual health knowledge and shaped their interactions with health services, though these networks were influenced by prevailing community stigmas. CONCLUSIONS: Difficulty situating PrEP within existing safer sex beliefs contributes to limited perceptions of personal PrEP candidacy. To increase PrEP uptake in UK Black African/Black Caribbean women, interventions will need to enable women to advance their knowledge of PrEP within the broader context of their sexual health and relationships. PrEP service models will need to include trusted 'non-sexual health-specific' community services such as general practice.

'Willy nilly' doctors, bad patients, and resistant bodies in general public explanations of antimicrobial resistance.

Increased public engagement is a feature of policy and communications focussed on the reduction of antimicrobial resistance. Explaining antimicrobial resistance for general publics has proven difficult and they continue to endorse apparently mistaken knowledge, including the conflation of antimicrobial resistance with the notion of the resistant body. We interviewed members of the general public in Melbourne, Australia, to explore explanatory models for antimicrobial resistance and shed light on the persistence of the resistant body assumption and related concepts. In the face of AMR's complexity and the portended antibiotic apocalypse, publics rely on a heavily inscribed understanding of the body defending itself against microbes. Publics also read antibiotic misuse and overuse messages as the responsibility of other patients and medical practitioners, and not themselves. Significantly, the scientific world view that has created expert knowledge about AMR hails publics in ways that discredits them and limits their capacity to take action. Increased engagement with publics will be required to ensure that collaborative and sustainable AMR approaches are fashioned for the future.

What are the barriers and challenges faced by adolescents when searching for sexual health information on the internet? Implications for policy and practice from a qualitative study.

OBJECTIVES: As sexual health information is increasingly presented digitally, and adolescents are increasingly seeking sexual health information on the internet, it is important to explore the challenges presented by this developing source of information provision. This study examined the key barriers and challenges faced by young people when accessing and using sexual health information online. METHODS: A novel qualitative approach was used which combined paired interviews with real-time online activities. A purposive sample of 49 young people aged between 16 and 19 years and diverse in terms of gender, sexuality, religion and socio-demographic background were recruited from areas across Scotland. Data analysis comprised framework analysis of conversational data (including pair interactions), descriptive analysis of observational data, and data integration. RESULTS: This study highlighted practical and socio-cultural barriers to engagement with online sexual health content. Key practical barriers included difficulty filtering overabundant content; limited awareness of specific, relevant, trusted online sources; difficulties in finding locally relevant information about services; and difficulties in navigating large organisations' websites. Key socio-cultural barriers included fear of being observed; wariness about engaging with visual and auditory content; concern about unintentionally accessing sexually explicit content; and reticence to access sexual health information on social networking platforms or through smartphone applications. These practical and socio-cultural barriers restricted access to information and influenced searching practices. CONCLUSION: This study provides insights into some of the key barriers faced by young people in accessing and engaging with sexual health information and support online. Reducing such challenges is essential. We highlight the need for sexual health information providers and intervention developers to produce online information that is accurate and accessible; to increase awareness of and promote reliable, accessible sources; and to be sensitive to young people's concerns about 'being seen' accessing sexual health information regarding audio-visual content and platform choice.

Age-related factors influence HIV testing within subpopulations: a cross-sectional survey of MSM within the Celtic nations.

OBJECTIVES: Despite a recent fall in the incidence of HIV within the UK, men who have sex with men (MSM) continue to be disproportionately affected. As biomedical prevention technologies including pre-exposure prophylaxis are increasingly taken up to reduce transmission, the role of HIV testing has become central to the management of risk. Against a background of lower testing rates among older MSM, this study aimed to identify age-related factors influencing recent (≤12 months) HIV testing. METHODS: Cross-sectional subpopulation data from an online survey of sexually active MSM in the Celtic nations-Scotland, Wales, Northern Ireland and Ireland (n=2436)-were analysed to compare demographic, behavioural and sociocultural factors influencing HIV testing between MSM aged 16-25 (n=447), 26-45 (n=1092) and ≥46 (n=897). RESULTS: Multivariate logistic regression demonstrated that for men aged ≥46, not identifying as gay (OR 0.62, CI 0.41 to 0.95), location (Wales) (OR 0.49, CI 0.32 to 0.76) and scoring higher on the personalised Stigma Scale (OR 0.97, CI 0.94 to 1.00) significantly reduced the odds for HIV testing in the preceding year. Men aged 26-45 who did not identify as gay (OR 0.61, CI 0.41 to 0.92) were also significantly less likely to have recently tested for HIV. For men aged 16-25, not having a degree (OR 0.48, CI 0.29 to 0.79), location (Republic of Ireland) (OR 0.55, CI 0.30 to 1.00) and scoring higher on emotional competence (OR 0.57, CI 0.42 to 0.77) were also significantly associated with not having recently tested for HIV. CONCLUSION: Key differences in age-related factors influencing HIV testing suggest health improvement interventions should accommodate the wide diversities among MSM populations across the life course. Future research should seek to identify barriers and enablers to HIV testing among the oldest and youngest MSM, with specific focus on education and stigma.

The Effectiveness of Social Marketing Interventions to Improve HIV Testing Among Gay, Bisexual and Other Men Who Have Sex with Men: A Systematic Review.

HIV testing is central to biomedical HIV prevention, but testing among men who have sex with men remains suboptimal. We evaluated effectiveness of mass media and communication interventions to increase HIV testing and explored patterns between study type, internal validity and intervention effectiveness for the first time. Five databases were searched for articles published between 2009 and 2016 using standard MeSH terms. Eligible studies were quality appraised using standard checklists for risk of bias. Data were extracted and synthesised narratively. Nineteen studies met inclusion criteria; 11 were cross-sectional/non-comparative studies, four were pre/post or interrupted time series, three were randomised controlled trials (RCTs) and one was a case study. Risk of bias was high. Five cross-sectional (two graded as high internal validity, one medium and two low) and one RCT (medium validity) reported increased HIV testing. Further work is required to develop and evaluate interventions to increase frequency and maintenance of HIV testing.

Provision of online HIV-related information to gay, bisexual and other men who have sex with men: a health literacy-informed critical appraisal of Canadian agency websites.

Background HIV risk and prevention information is increasingly complex and poses challenges for gay, bisexual and other men who have sex with men (GBMSM) seeking to find, understand and apply this information. A directed content analysis of Canadian HIV websites to see what information is provided, how it is presented and experienced by users, was conducted. METHODS: Eligible sites provided information relevant for GBMSM on HIV risk or prevention, were from community or government agencies, and were aimed at the public. Sites were found by using a Google search using French and English search terms, from expert suggestions and a review of links. Eligibility and content for review was determined by two reviewers, and coded using a standardised form. Reading grade level and usability scores were assessed through Flesch-Kincaid and LIDA instruments. RESULTS: Of 50 eligible sites, 78% were from community agencies and 26% were focussed on GBMSM. Overall, fewer websites contained information on more recent biomedical advances (e.g. pre-exposure prophylaxis, 10%) or community-based prevention strategies (e.g. seroadaptive positioning, 10%). Many sites had high reading levels, used technical language and relied on text and prose. And 44% of websites had no interactive features and most had poor usability scores for engageability. CONCLUSIONS: Overall, less information about emerging topics and a reliance on text with high reading requirements was observed. Our study speaks to potential challenges for agency website operators to maintain information relevant to GBMSM which is up-to-date, understandable for a range of health literacy skills and optimises user experience.

Effectiveness of interventions to improve the public's antimicrobial resistance awareness and behaviours associated with prudent use of antimicrobials: a systematic review.

Background: A global antimicrobial resistance (AMR) awareness intervention targeting the general public has been prioritized. Objectives: To evaluate the effectiveness of interventions that aim to change AMR awareness and subsequent stewardship behaviours amongst the public. Methods: Five databases were searched between 2000 and 2016 for interventions to change the public's AMR awareness and/or antimicrobial stewardship behaviours. Study designs meeting the Cochrane Effective Practice and Organization of Care (EPOC) criteria, non-controlled before-and-after studies and prospective cohort studies were considered eligible. Participants recruited from healthcare settings and studies measuring stewardship behaviours of healthcare professionals were excluded. Quality of studies was assessed using EPOC risk of bias criteria. Data were extracted and synthesized narratively. Registration: PROSPERO international prospective register of systematic reviews (PROSPERO 2016: CRD42016050343). Results: Twenty studies were included in the review with nine meeting the EPOC criteria. The overall risk of bias was high. Nineteen studies were conducted in high-income countries. Mass media interventions were most common (n = 7), followed by school-based (n = 6) and printed material interventions (n = 6). Seventeen studies demonstrated a significant effect on changing knowledge, attitudes or the public's antimicrobial stewardship behaviours. Analysis showed that interventions targeting schoolchildren and parents have notable potential, but for the general public the picture is less clear. Conclusions: Our work provides an in-depth examination of the effectiveness of AMR interventions for the public. However, the studies were heterogeneous and the quality of evidence was poor. Well-designed, experimental studies on behavioural outcomes of such interventions are required.
