Recruiting and Engaging Heterosexual-Identified Men Who have Sex with Men: A Brief Report of Considerations for Sex Researchers.

Heterosexual-identified men who have sex with men (H-MSM) are a unique population difficult to identify and recruit for research and practice. Yet, engaging H-MSM remains a top research priority to learn more about this population's health needs. A scoping review was conducted to develop a stronger understanding of recruitment patterns involving H-MSM in research.

PrEP use and unmet PrEP-need among men who have sex with men in London prior to the implementation of a national PrEP programme, a cross-sectional study from June to August 2019.

Background: Access to prevention options, including HIV pre-exposure prophylaxis (PrEP), remains a public health priority for gay, bisexual, and other men who have sex with men (MSM), especially in London. We describe PrEP use in a London community sample of MSM before the introduction of a national PrEP programme in October 2020.

Methods: From June-August 2019, MSM aged ≥ 18 recruited from London commercial venues were asked to self-complete a sexual health questionnaire and provide an oral fluid sample for anonymous HIV antibody testing.

Patterns of sexualised recreational drug use and its association with risk behaviours and sexual health outcomes in men who have sex with men in London, UK: a comparison of cross-sectional studies conducted in 2013 and 2016.

Objective: London has one of the highest identified prevalence of chemsex (sexualised recreational drug use) among men who have sex with men (MSM) in Europe. We examine MSM's patterns of chemsex and its association with HIV/STI risk behaviours, STI diagnoses and sexual healthcare-seeking behaviours, including if HIV testing behaviour met UK national guidelines (three monthly if engaging in chemsex).

Methods: Cross-sectional survey data from 2013 (n=905) and 2016 (n=739) were collected using anonymous, self-administered questionnaires from MSM recruited in commercial gay venues in London, UK.

Household structure and its association with sexual risk behaviours and sexual health outcomes: evidence from a British probability sample survey.

Objectives: Economic and social changes over the last 20 years have led to changes in the living situations of young people in Britain. A person's home-life context might influence their sexual behaviour, with implications for their sexual healthcare needs; we investigated this hypothesis.

Methods: Britain's third National Survey of Sexual Attitudes and Lifestyles, a probability sample survey undertaken in 2010-2012, interviewed 15 162 men and women aged 16-74 years in Britain (with 3869 aged 16-24 years).

Application of the COM-B model to barriers and facilitators to chlamydia testing in general practice for young people and primary care practitioners: a systematic review.

Background: Chlamydia is a major public health concern, with high economic and social costs. In 2016, there were over 200,000 chlamydia diagnoses made in England. The highest prevalence rates are found among young people.
