Conference Paper
COVID-19 related restrictions have impacted the dynamics of romantic relationships, with many cohabiting partners spending more time together and non-cohabiting partners much less. We explored qualitatively, the vulnerabilities (characteristics that decreased resilience) and stressors that impacted intimate relationships following the initial COVID...
Conference Paper
Background COVID-19 restrictions led to widespread disruption of SRH services in Britain following the first national lockdown (23/3/2020). One-in-ten people who tried to access SRH services during reported being unable to do so (Natsal-COVID). We used mixed-methods research to quantify unmet need and explore its context and impact. Methods 6,657...
Conference Paper
Background Worldwide, efforts to control SARS-CoV-2 transmission have included lockdowns and restrictions on contact with others, including sexual partners. Our research (Natsal-COVID) indicates that in the UK, 10% of people aged 18–59 had physical or sexual contact with a romantic or sexual partner outside their household (PCOH) during a period in...
Conference Paper
Background Sexual wellbeing is intrinsic to public health but long-standing conflation of sexual health and sexual wellbeing has limited our ability to address everyday sexual issues. This study proposed a seven-domain model, and developed and validated a brief measure for community surveys. Method Domains of sexual wellbeing were determined throu...
Conference Paper
Background The introduction of social distancing in response to the COVID-19 pandemic led to reduced STI/HIV service provision in the UK.

Full-text available
Men-who-have-sex-with-men (MSM) carry a disproportionate burden of sexually transmitted infections across Europe. Health planners require sexual health needs assessment data to respond appropriately. In addition, surveillance of risk and precaution behaviours in this population enables evaluative judgements of policy responses. The European MSM Int...
Article
Full-text available
Some men who have sex with men (MSM) were assigned female at birth (AFB) and/or identify as trans men. Little is known about how these men differ from other MSM. We compared sexual and mental health indicators from the European MSM Internet Survey (EMIS-2017), comparing men AFB and/or currently identifying as trans men with those assigned male at b...
Article
Full-text available
Background Chemsex, the use of select psychoactive drugs to enhance sexual experience, typically among men who have sex with men (MSM), is associated with sexual behaviours with higher STI risk. Understanding patterns of chemsex among MSM as well as the characteristics and sexual health service engagement of chemsex participants is important for de...
Conference Paper
Background In Europe and the Americas, men-who-have-sex-with-men (MSM) are heavily affected by HIV. Having traditionally relied mainly on condoms and sero-adaptive behaviours to prevent HIV transmission, more recently biomedical prevention strategies such as pre-exposure prophylaxis (PrEP) among HIV-negative and viral suppression among HIV-diagnose...

Understanding characteristics of MSM who engage in chemsex and their use of STI clinics is important for developing interventions. Methods Between 5/2016-5/2017, 3,358 MSM (...
Article
Full-text available
Objectives In the UK, men who have sex with men (MSM) bear a disproportionate sexually transmitted infection (STI) burden. We investigated MSM's STI knowledge; whether their STI testing behaviour met national guidelines (annually if sexually active; 3‐monthly if engaging in STI risk behaviours); and the relationship between STI testing in the last...
Article
Background Illicit drug use among men who have sex with men (MSM) has been associated with sexual risk and HIV. Less is documented about associations with other sexually transmissible infections (STIs). The aim of the present study was to determine whether the use of drugs commonly associated with chemsex is associated with increased risk of gonorr...
Article
Full-text available
Abstract Background: Rates of sexually transmissible infections (STIs) have increased over recent years among gay men and other men who have sex with men (MSM) in England and Wales. HIV diagnoses remain high in this group and men with diagnosed HIV are disproportionally affected by STIs. MSM are therefore a priority for health promotion efforts to...
Article
Full-text available
Background Sexually transmitted infection (STI) surveillance is vital for tracking the scale and pattern of epidemics; however, it often lacks data on the underlying drivers of STIs. Objective This study aimed to assess the acceptability and feasibility of implementing a bio-behavioral enhanced surveillance tool, comprising a self-administered Web...
Article
Background: Evidence to understand which gay and bisexual men (GBM) inject drugs remains scant, especially in the UK. We describe correlates of last-year injecting in UK GBM, and characterise subgroups of GBM who inject drugs by types of drugs used. Methods: Using data from the 2014 Gay Men's Sex Survey, an opportunistic internet-based survey co...
Article
Background: Analysis of specific drug use patterns in men who have sex with men (MSM) is important in targeting HIV prevention and harm reduction interventions and in developing a fuller picture of drug use in context beyond consideration of use of specific drugs in isolation. Objectives: We sought to develop a typology of recent drug use in MSM...
Article
Background Although a world-class routine sexually transmitted infections (STI) surveillance system, England's Genitourinary Medicine Clinic Activity Dataset (GUMCAD) collects limited behavioural data, restricting insights into drivers of STI transmission. We developed a bio-behavioural enhanced surveillance tool (BBEST) comprising a short, self-a...
Article
Full-text available
Objectives To explore the experiences and views of men who have sex with men (MSM) on attending clinical sexual health services and their preferences regarding service characteristics in the context of the disproportionate burden of STIs experienced by this group. The wider study aim was to develop a risk assessment tool for use in sexual health cl...
Conference Paper
Introduction As a result of high burden of infection, men who have sex with men (MSM) are a priority for sexually transmitted infection (STI) prevention interventions including promoting regular testing. Effective intervention design requires understanding of MSM’s knowledge and perceptions of STIs and their social representations which may affect...
Conference Paper
Introduction STI diagnosis rates vary considerably by ethnicity in England and persist after adjusting for confounding factors including deprivation and sexual behaviour. We examine the extent to which partner notification (PN) experiences differ by ethnicity as a possible contributing factor to this health inequality. Method 3986 patients attendi...
Conference Paper
Introduction Behavioural surveys can provide insight into the attitudes and context associated with risk of sexually transmitted infections (STIs), but interpretation is hampered by theirreliance on self-reported STI history rather than confirmed diagnoses. We aimed to determine the feasibility and acceptability of linking clinic patients’ online s...
Article
Objectives: To examine ethnic group differences in HIV testing and sexual behaviours among a large sample of gay and bisexual men (GBM), 13?years after similar observations were made, assess national HIV prevention responses and inform planning priorities. Methods: Cross-sectional convenience self-completion online survey in summer 2014, designe...
Article
Background: Anecdotal evidence suggests that men who have sex with men (MSM) are increasingly combining sex and illicit drugs (an activity referred to as 'chemsex'), in particular GHB/GBL, ketamine, crystal meth, or mephedrone (here called 4-chems). Use of such drugs has been associated with mental health and sexual health harms. We aim to compare...
Article
Background: 'Chemsex' refers to the combining of sex and illicit drugs, typically mephedrone, GHB/GBL, and crystal methamphetamine. While numerous studies have examined the role of illicit drugs in sexual risk taking, less attention has been paid to the broader social context and structures of their use among gay men. Given their established role...

Full-text available
Background: Traditionally, GPs have little involvement in the care of PWHIV. However, as HIV becomes a chronic condition and the population of PWHIV ages, there is a need to increase this involvement. Despite high levels of GP registration, the majority of PWHIV in London report that their GP is not involved in their HIV care. Methods: This paper...
Article
Chemsex is a colloquial term used by gay men in some parts of the UK to describe the use of psychoactive substances (typically mephedrone, GHB/GBL or crystal methamphetamine) during sex. Use of these drugs by gay men in London appears to have risen sharply from relatively low levels and, as yet, there is little data to inform appropriate harm reduc...
