Characteristics associated with frequent sexually transmitted infection (STI) testing in a community-based sample of gay, bisexual, and other men who have sex with men (GBMSM), United Kingdom, 2024
In the UK, gay, bisexual, and other men who have sex with men (GBMSM) at risk of sexually transmitted infections (STIs) are recommended quarterly testing, but it is not known how many are following this recommendation. We described prevalence and correlates of frequent STI testing amongst GBMSM. We analysed data from the community-based Reducing Inequalities in Sexual Health (RiiSH) online survey of GBMSM, with recruitment in November-December 20…
Factors affecting the implementation of a whole-school relationships and sexual health intervention
Whole-school relationships and sexual health interventions represent promising approaches to promoting healthy sexual development. However, data from a randomised controlled trial of the Positive Choices whole-school intervention demonstrate these may be challenging to implement in English secondary schools. We draw on qualitative data to examine staff perspectives on the implementation of the intervention and the factors affecting delivery. Inte…
Understanding the limited effectiveness of a whole-school relationships and sexual-health programme
Previous trials of whole-school relationships and sexual-health programmes have not reported on fidelity, reach or acceptability, despite the importance of these factors for interpreting outcomes. Our trial of the Positive Choices whole-school relationships and sexual-health programme found limited effectiveness in secondary schools in England. We aimed to understand whether sub-optimal fidelity, reach or acceptability might explain the results. …
PrEPped for Covid? The association between HIV-PrEP use and Covid-19 among men and gender diverse people who have sex with men
Oral tenofovir and emtricitabine taken as pre-exposure prophylaxis (HIV-PrEP) is highly effective at reducing Human Immunodeficiency Virus (HIV) acquisition. Nucleotide analogues have also been shown to inhibit Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) polymerase activity in vitro, raising the question as to whether tenofovir-based HIV-PrEP could be useful for the prevention and treatment of COVID-19. We sought to examine the a…
Effects of a whole-school relationships and sexual health intervention on non-competent sexual debut
BACKGROUND: Relationships and sex education (RSE) impacts some sexual behaviours but could be strengthened by incorporating whole-school approaches (eg, building engagement, providing contraception). These can prevent pregnancies and sexually-transmitted infections but are unevaluated in UK schools. METHODS: A cluster-randomised trial of 'Positive Choices' compared it with usual practice in English secondary schools. Intervention comprised: RSE, …
Disabled people faced greater challenges accessing sexual and reproductive health services in the first year of the Covid-19 pandemic in Britain
Our study provides evidence that disabled people in Britain were more likely to have difficulty accessing SRH services during COVID-19. However, the extent to which these disparities were created or exacerbated by the pandemic, and whether inequalities persist, is not clear. Our results are relevant for contemporary service design, given that many changes introduced during the pandemic have endured
Longitudinal Assessment of Sexual Behavior and Relationship Quality During the First Year of the Covid-19 Pandemic in Britain
While the impact of social restrictions on sexual and romantic life early in the COVID-19 pandemic has been widely studied, little is known about impacts beyond the initial months. We analyzed responses from 2,098 British adults (aged 18-59) taking part in the Natsal-COVID study (Waves 1 and 2). Participants were recruited via a web panel and surveyed twice: four months and one year after the start of the UK's first national lockdown (July 2020 a…
Trends in Masturbation Prevalence and Associated Factors
Previous evidence suggests that masturbation has a complementary function for women and a compensatory function for men. However, in light of changing attitudes toward masturbation, this gendered model of compensation versus complementation may not remain valid. We studied trends in masturbation prevalence over time and identified sociodemographic, sexual life, attitudinal, and relationship factors associated with reporting masturbation. Data wer…
Pornography Use Among Adults in Britain
Pornography use is common but stigmatized. In this study, we present a qualitative analysis of the patterns of, and motivations for, using pornography and how the stigma of using pornography manifests in participants’ accounts. We draw on Meisenbach’s (2010) theory of stigma management communication (SMC) to deepen our understanding of how participants managed potential stigma. Data come from 40 semistructured interviews with a diverse sample of …
The mechanisms by which a whole-school intervention might improve sexual health
Whole-school interventions go beyond classroom education, promoting health by modifying school environments. These can be effective in delaying sexual debut and increasing contraception use but mechanisms are poorly understood. Qualitative research within realist evaluation can explore mechanisms via building 'context-mechanism-outcome configurations', describing how interventions trigger mechanisms that interact with context to generate outcomes…
Knowledge, uptake and intention to use antibiotic post-exposure prophylaxis and meningococcal B vaccine (4CMenB) for gonorrhoea among a large, online community sample of men and gender-diverse individ…
Novel STI prevention interventions, including doxycycline post-exposure prophylaxis (doxyPEP) and meningococcal B vaccination (4CMenB) against gonorrhoea, have been increasingly examined as tools to aid STI control. There is evidence of the efficacy of doxyPEP in preventing bacterial STIs; however, limited data exist on the extent of use in the UK. We examined self-reported knowledge and use of antibiotic post-exposure prophylaxis (PEP), and inte…
Examining changes in sexual lifestyles in Britain between 1990–2010
Our results indicate the viability of LCA models to assess change over time for complex behavioural phenomena. They align with previous findings, namely changing sexual lifestyles in Britain in recent decades, partnership number driving class assignment, and significant sex differences in sexual lifestyles. This approach can be used to extend previous LCA models (e.g., to investigate the impact of COVID-19 on sexual lifestyles) and to support emp…
How does online postal self-sampling (OPSS) shape access to testing for sexually transmitted infections (STIs)? A qualitative study of service users
Our findings constitute one of the largest qualitative studies to have explored OPSS and offer valuable insights to providers. OPSS shapes access to STI testing in a number of ways, including facilitating access in many circumstances, but users also want to retain access to clinic-based services, particularly for when they believe they need support beyond STI testing
Conceptualizing Sexual Wellbeing
Despite increasing scientific and policy interest in sexual wellbeing, it remains poorly conceptualized. Many studies purporting to measure it instead measure related but distinct concepts, such as sexual satisfaction. This lack of conceptual clarity impedes understanding, measuring, and improving sexual wellbeing. We present qualitative research from multi-stage, mixed-methods work to develop a new measure of sexual wellbeing (Natsal-SW) for the…
Covid-19 infection and vaccination uptake in men and gender-diverse people who have sex with men in the UK
In this community sample, COVID-19 vaccine uptake was high overall, though lower among younger age-groups, gender minorities, and those with poorer well-being. Efforts are needed to limit COVID-19 related exacerbation of health inequalities in groups who already experience a greater burden of poor health relative to other men who have sex with men
Sexting among British adults
Sexting has generated considerable public and professional interest with concerns centring on young people, and potential harms to mental and sexual health. Little research thus far has explored the practice among adults and none has focused on the cultural norms relating to the emotional experience of sexting across different ages and genders. We conducted 40 semi-structured interviews with a diverse sample of adults aged 18-59 years in Britain …
Development and Validation of a Brief Measure of Sexual Wellbeing for Population Surveys
Sexual wellbeing is an important aspect of population health. Addressing and monitoring it as a distinct issue requires valid measures. Our previous conceptual work identified seven domains of sexual wellbeing: security; respect; self-esteem; resilience; forgiveness; self-determination; and comfort. Here, we describe the development and validation of a measure of sexual wellbeing reflecting these domains. Based on the analysis of 40 semi-structur…
Prevalence and Correlates of Fearing a Partner During the Covid-19 Pandemic in Britain
Remote methods for research on violence against women and children
Collecting data to understand violence against women and children during and after the COVID-19 pandemic is essential to inform violence prevention and response efforts. Although researchers across fields have pivoted to remote rather than in-person data collection, remote research on violence against women, children and young people poses particular challenges. As a group of violence researchers, we reflect on our experiences across eight studie…
Associations with sub-optimal clinic attendance and reasons for missed appointments among heterosexual women and men living with HIV in London
Poor engagement in HIV care is associated with poorer health outcomes and increased mortality. Our survey examined experiential and circumstantial factors associated with clinic attendance among women (n = 250) and men (n = 106) in London with heterosexually-acquired HIV. While no associations were found for women, among men, sub-optimal attendance was associated with insecure immigration status (25.6% vs. 1.8%), unstable housing (32.6% vs. 10.2%…
Initial Impacts of Covid-19 on Sex Life and Relationship Quality in Steady Relationships in Britain
Intimate relationships are ubiquitous and exert a strong influence on health. Widespread disruption to them may impact wellbeing at a population level. We investigated the extent to which the first COVID-19 lockdown (March 2020) affected steady relationships in Britain. In total, 6,654 participants aged 18-59 years completed a web-panel survey (July-August 2020). Quasi-representativeness was achieved via quota sampling and weighting. We explored …
Cognitive testing of a survey instrument to assess sexual practices, behaviours, and health outcomes
BACKGROUND: Population level data on sexual practices, behaviours and health-related outcomes can ensure that responsive, relevant health services are available for all people of all ages. However, while billions of dollars have been invested in attempting to improve sexual and reproductive health (including HIV) outcomes, far less is understood about associated sexual practices and behaviours. Therefore, the World Health Organization embarked on…
How does the sexual, physical and mental health of young adults not in education, employment or training (Neet) compare to workers and students
Harmful health behaviours (men) and poor health outcomes (women) clustered more in those who are NEET. This points to a possible syndemic effect of NEET status on general ill health, especially for women. Our paper is novel in highlighting that elevated risk pertains to sexual as well as mental and physical health
Salivary Testosterone and Sexual Function and Behavior in Men and Women
Using data from the third British National Survey of Sexual Attitudes and Lifestyles (Natsal-3) we examined associations between salivary testosterone (Sal-T) and sexual function and behavior. Single morning saliva samples were self-collected from a subsample of participants aged 18-74 years and analyzed using mass spectrometry. 1,599 men and 2,123 women were included in the analysis (40.6% of those invited to provide a sample). We adjusted for c…
Online Sexual Partner Seeking as a Social Practice
Once perceived as a means for those unsuccessful at traditional dating, online dating has become normalized as a way to seek sexual or romantic partners. In 2019, we interviewed 40 British adults on the role of digital technologies in their sexual lives; this paper draws on the accounts of 22 who had used such technologies for seeking partners. We analyzed qualitative accounts of online partner seeking as a social practice, drawing on a sample di…
Estimating the Prevalence of Sexual Function Problems
Establishing the clinical significance of symptoms of sexual dysfunction is challenging. To address this, the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) introduced two new morbidity criteria (duration and symptom severity) to the existing criteria of distress. This study sought to establish the impact of these three criteria on the population prevalence of sexual function problems. The data come from a nati…
Who reports absence of sexual attraction in Britain? Evidence from national probability surveys
There is little evidence about the prevalence of absence of sexual attraction, or the characteristics of people reporting this, often labelled asexuals. We examine this using data from two probability surveys of the British general population, conducted in 1990–1991 and 2000–2001. Interviewers administered face-to-face and self-completion questionnaires to people aged 16–44 years (N = 13,765 in 1990–1991; N = 12,110 in 2000–2001). The proportion …

Why Do Men Report More Opposite-Sex Sexual Partners Than Women? Analysis of the Gender Discrepancy in a British National Probability Survey
In a closed population and defined time period, the mean number of opposite-sex partners reported by men and women should be equal. However, in all surveys, men report more partners. This inconsistency is pivotal to debate about the reliability of self-reported sexual behavior. We used data from the third National Survey of Sexual Attitudes and Lifestyles (Natsal-3), a probability sample survey of the British population, to investigate the extent…
Women Who Report Having Sex With Women
Objectives. We estimated the prevalence of same-sex experience among women and compared women reporting sex with women and men and women reporting sex exclusively with women with women reporting sex exclusively with men, in terms of sociodemographics and sexual, reproductive, and general health risk behaviors and outcomes. Methods. We used a British probability survey (n=6399 women, aged 16 to 44 years) conducted from 1999 to 2001 with face-to-fa…
Scripting sexual function
The biomedical model assumes universal agreement in what it means to have a functioning sex life. In reality there is significant variation in the criteria that individuals employ in assessing their sex lives. We use a scripting approach to understand the meaning of sexual function from a lay perspective. Based on the accounts of 32 individuals representing a range of sexual function experience, we identified three scripts employed by participant…
Is “Sexual Competence” at First Heterosexual Intercourse Associated With Subsequent Sexual Health Status
The timing of first sexual intercourse is often defined in terms of chronological age, with particular focus on "early" first sex. Arguments can be made for a more nuanced concept of readiness and appropriateness of timing of first intercourse. Using data from the third National Survey of Sexual Attitudes and Lifestyles (Natsal-3), conducted in 2010-2012, this study examined whether a context-based measure of first intercourse-termed sexual compe…

The Natsal-SF Measure of Sexual Function
The Natsal-SF is a psychometrically validated measure of sexual function for use in community health surveys, derived from 17 questions reflecting three components of sexual function. Scoring requires knowledge of complex statistical modeling and, given the methodological complexities, we assessed the validity of two simplified scoring methods calculated using the factor loadings produced when originally modeling the Natsal-SF items. Method 1 use…
Improving Questions on Sexual Partnerships
Patterns of sexual partnership formation and dissolution are key drivers of sexually transmitted infection transmission. Sexual behavior survey participants may be unable or unwilling to report accurate details about their sexual partners, limiting the potential to capture information on sexual mixing and timing of partnerships. We examined how questions were interpreted, including recall strategies and judgments made in selecting responses, to i…

Prevalence of Masturbation and Associated Factors in a British National Probability Survey
The sexual attitudes and lifestyles of London's Eastern Europeans (Sallee Project)
The SALLEE project has benefited from using quantitative research to provide generalisable data on a range of variables and qualitative research to add in-depth understanding and interpretation. The social mapping exercise successfully located a large number of CEE migrants for the community sample and is recommended for other migrant populations, especially when little or no official data are available for this purpose. The project has collected…
Testing for sexually transmitted infections in general practice
There are substantial geographical differences in the intensity of chlamydia and HIV testing in general practice. Interventions to facilitate sexually transmitted infection and HIV testing in general practice are needed to improve access to effective sexual health care. The use of routinely-collected laboratory, practice-level and demographic data for monitoring sexual health service provision and informing service planning should be more widely …
Estimating the Likely Public Health Impact of Partner Notification for a Clinical Service
Objectives. We present the first evidence-based method for estimating public health and cost impacts of partner notification (PN) that takes account of sexual partnership type. Methods. Our algorithm uses routine clinical data, probability survey data, and transmission parameters. We propose 2 new epidemiological concepts to quantify PN impact: “[the] absolute reduction in onward transmission” and its reciprocal, “[the] number needed to treat to …

OP74 Measuring Sexual Behaviour Comes of Age
Background The Health Survey for England (HSE) is a general health survey administered annually to a probability sample of people living in England. In 2010, the HSE included, for the first time, questions about sexual health, which previously were considered too sensitive for a general health survey. This paper compares the reporting of sexual behaviours by people aged 16–44 in HSE–2010 with data collected by the second British National Survey o…
Changes in sexual attitudes and lifestyles in Britain through the life course and over time
BACKGROUND: Sexual behaviour and relationships are key components of wellbeing and are affected by social norms, attitudes, and health. We present data on sexual behaviours and attitudes in Britain (England, Scotland, and Wales) from the three National Surveys of Sexual Attitudes and Lifestyles (Natsal). METHODS: We used a multistage, clustered, and stratified probability sample design. Within each of the 1727 sampled postcode sectors for Natsal-…
Sexual function in Britain
BACKGROUND: Despite its importance to sexual health and wellbeing, sexual function is given little attention in sexual health policy. Population-based studies are needed to understand sexual function across the life course. METHODS: We undertook a probability sample survey (the third National Survey of Sexual Attitudes and Lifestyles [Natsal-3]) of 15,162 individuals aged 16-74 years who lived in Britain (England, Scotland, and Wales). Interviews…

Evaluating Maori community initiatives to promote Healthy Eating, Healthy Action
Māori, the indigenous people of Aotearoa New Zealand, experience poorer health than non-Māori across a range of health measures. Interventions focused at an individual level have proved largely ineffective; 'bottom-up' approaches where communities determine their own priorities may be more sustainable than 'top-down' approaches where goals are determined by health authorities. The purpose of this paper is to illustrate an innovative health promot…
Examining the potential public health benefit of offering STI testing to men in amateur football clubs
Relative to young men in the general population, football club members who completed the SPORTSMART survey reported greater sexual risk behaviour but similar STI/HIV risk perception and STI testing history. Offering STI testing in amateur football clubs may therefore widen access to STI testing and health promotion messages for men at higher STI risk, which, given the minority currently testing and the popularity of football in England, should yi…

The health and well-being of men who have sex with men (MSM) in Britain
MSM are disproportionately affected by a broad range of harmful health behaviours and poor health outcomes. Although often observed for a minority of MSM, many health inequalities were seen in combination such that policies and practices aimed at improving the health and well-being of MSM require a holistic approach, regardless of clinical specialty
How social representations of sexually transmitted infections influence experiences of genito-urinary symptoms and care-seeking in Britain
This is an ongoing mixed methods study collecting, analysing and synthesising linked data from a national survey and follow-up semi-structured interviews. It adds explanatory potential to existing national survey data and is likely to inform future surveys about sexual health. Given the current uncertainty around service provision in Britain, this study provides timely data about symptom experiences and care-seeking behaviour which may inform fut…

Can psychosocial and socio-demographic questions help identify sexual risk among heterosexually-active women of reproductive age? Evidence from Britain’s third National Survey of Sexual Attitudes and …
Reported weekly binge drinking, early sexual debut, and age group may help target STI testing and/or CAS among women. Further research is needed to examine the proportion of sexual risk explained by these factors, the acceptability of these questions to women in primary care and the need to customise them for community and other settings
Sexual identity, attraction and behaviour in Britain
BACKGROUND: Sexual orientation encompasses three dimensions: sexual identity, attraction and behaviour. There is increasing demand for data on sexual orientation to meet equality legislation, monitor potential inequalities and address public health needs. We present estimates of all three dimensions and their overlap in British men and women, and consider the implications for health services, research and the development and evaluation of public …
