Prevalence and correlates of 'sexual competence' at first heterosexual intercourse among young people in Britain

Effectiveness of a Comprehensive School-Based Sex Education Program for Young Adolescents in the Netherlands

Most sexual education programs traditionally focused on providing sexual information regarding the risks of sex. However, current studies on sexual behavior in youth show a need for truly comprehensive sex education approaches with a sex-positive focus on sexuality, that effectively improve sexual competence. Therefore, in the current study the effectiveness of "Love is…", a four lesson school-based program based on the Sexual Interactional Competence model and Attitude-Social-Influence-Self-Efficacy-model was studied. A cluster-randomized controlled trial on the effectiveness of "Love is…" was conducted in 2018-2020. The sample consisted of 1160 adolescents in grades 8 and 9 from nine schools in the Netherlands. The sample was 48% female, 34% Dutch/Caucasian, 41% none-religious and 50% higher educated. They were randomized at class level into a program group [n = 32 classes; 567 students (Mage = 13.74 (SD = 0.74))] and a control group [n = 31 classes; 593 students (Mage = 13.86 (SD = 0.73))]. Results showed that "Love is…" increased sexual knowledge, that adolescents in the program group showed less cyber victim blaming attitudes and increased in communications skills after the program. In conclusion, the current study shows that "Love is…" was effective not only on the knowledge level, but also regarding sexual attitudes and competences. However, due to the developmental process of sexuality, there is a necessity to continue lessons in following grades through booster sessions by reinforcing competences as communicating comfortably about sexuality.On 12 November 2019 the study design and hypotheses were registered in the Dutch Trial Registration, number NL8150.

Feasibility and acceptability of a whole-school social-marketing intervention to prevent unintended teenage pregnancies and promote sexual health: evidence for progression from a pilot to a phase III randomised trial in English secondary schools

BACKGROUND

Reducing unintended teenage pregnancy and promoting adolescent sexual health remains a priority in England. Both whole-school and social-marketing interventions are promising approaches to addressing these aims. However, such interventions have not been rigorously trialled in the UK and it is unclear if they are appropriate for delivery in English secondary schools. We developed and pilot trialled Positive Choices, a new whole-school social marketing intervention to address unintended teenage pregnancy and promote sexual health. Our aim was to assess the feasibility and acceptability of the intervention and trial methods in English secondary schools against pre-defined progression criteria (relating to randomisation, survey follow-up, intervention fidelity and acceptability and linkage to birth/abortion records) prior to carrying out a phase III trial of effectiveness and cost-effectiveness.

METHODS

Pilot RCT with integral process evaluation involving four intervention and two control schools in south-east England. The intervention comprised a student needs survey; a student/staff-led school health promotion council; a classroom curriculum for year-9 students (aged 13-14); whole-school student-led social-marketing activities; parent information; and a review of local and school-based sexual health services. Baseline surveys were conducted with year 8 (aged 12-13) in June 2018. Follow-up surveys were completed 12 months later. Process evaluation data included audio recording of staff training, surveys of trained staff, staff log books and researcher observations of intervention activities. Survey data from female students were linked to records of births and abortions to assess the feasibility of these constituting a phase III primary outcome.

RESULTS

All six schools were successfully randomised and retained in the trial. Response rates to the survey were above 80% in both arms at both baseline and follow-up. With the exception of the parent materials, the fidelity target for implementation of essential elements in three out of four schools was achieved. Student surveys indicated 80% acceptability among those who reported awareness of the programme and interviews with staff suggested strong acceptability. Linkage to birth/abortion records was feasible although none occurred among participants.

CONCLUSIONS

The criteria for progression to a phase III trial were met. Our data suggest that a whole-school social-marketing approach may be appropriate for topics that are clearly prioritised by schools. A phase III trial of this intervention is now warranted to establish effectiveness and cost-effectiveness. Births and terminations are not an appropriate primary outcome measure for such a trial.

Exploring Reflections, Motivations, and Experiential Outcomes of First Same-Sex/Gender Sexual Experiences among Lesbian, Gay, Bisexual, and Other Sexual Minority Individuals

First sex is an important event in an individual's sexual development. Previous literature has, however, primarily investigated first heterosexual sex, overlooking important contextual factors specific to same-sex/gender sexual experiences. Seventeen in-depth semi-structured interviews were conducted with lesbian, gay, bisexual, and other sexual minority (LGB+) individuals, ages 18-23 years. Four themes emerged from thematic analysis of reported thoughts, affect, and behavior. First, participants reported difficulty defining sex between same-sex/gender partners, especially women who reported that this undermined their personal relationships and identity. Second, participants met partners through several means; however, it was almost exclusively men who reported meeting their first partners online. Third, motivations for first same sex/gender sex included affirmation of personal sexual identity, sexual exploration, social expectation, and spontaneity. Fourth, participants felt underprepared for their first same-sex/gender sex, noting that their earlier sex and relationship education had not included information on same-sex/gender sex or LGB+ identities. Consequently, participants reported relying on experienced partners and seeking information on the internet, including pornography and social media. Greater cultural representation and more comprehensive sex education that recognizes sexual diversity is needed to better prepare LGB+ young people for early sexual encounters.

Perhaps It Was Too Soon: College Students' Reflections on the Timing of Their Sexual Debut

Early sexual debut has been a focus of social scientific research due to its association with adverse circumstances and negative outcomes. However, there has been a recent shift to considering not only chronological age, but also the degree to which the event is viewed to be optimally timed (i.e., the perception that it occurred at the "right time" versus too soon). The purpose of this study was to assess how individual/family background variables and contextual aspects of the experience (including partner and relationship aspects) are associated with both the actual age at sexual debut and the perceived acceptability of the timing of the event. Using data collected from students at a U.S. university between 1990 and 2019 (N = 6,430), several factors (in addition to chronological age) were associated with the perceived acceptability of the timing of sexual debut. Strong gender differences were found - women perceived their timing to be less acceptable, even though they did not differ from men in actual age at sexual debut. Other robust predictors of perceived acceptability included (lower) religious involvement and recalling desire (for the experience), pleasure, and lower guilt at the time. Only slight changes occurred over the 30-year period in age at sexual debut and perceived acceptability of the timing. Suggestions for future research are provided and implications for sex education/sexual health interventions are discussed.

The Positive Choices trial: study protocol for a Phase-III RCT trial of a whole-school social marketing intervention to promote sexual health and reduce health inequalities

Background

Positive Choices is a whole-school social marketing intervention to promote sexual health among secondary school students. Intervention comprises school health promotion council involving staff and students coordinating delivery; student survey to inform local tailoring; teacher-delivered classroom curriculum; student-run campaigns; parent information; and review of sexual/reproductive health services to inform improvements. This trial builds on an optimisation/pilot RCT study which met progression criteria, plus findings from another pilot RCT of the Project Respect school-based intervention to prevent dating and relationship violence which concluded such work should be integrated within Positive Choices. Young people carry a disproportionate burden of adverse sexual health; most do not report competence at first sex. Relationships and sex education in schools can contribute to promoting sexual health but effects are small, inconsistent and not sustained. Such work needs to be supplemented by ‘whole-school’ (e.g. student campaigns, sexual health services) and ‘social marketing’ (harnessing commercial marketing to social ends) approaches for which there is good review-level evidence but not from the UK.

Methods

We will conduct a cluster RCT across 50 schools (minimum 6440, maximum 8500 students) allocated 1:1 to intervention/control assessing outcomes at 33 months. Our primary outcome is non-competent first sex. Secondary outcomes are non-competent last sex, age at sexual debut, non-use of contraception at first and last sex among those reporting heterosexual intercourse, number of sexual partners, dating and relationship violence, sexually transmitted infections, and pregnancy and unintended pregnancy for girls and initiation of pregnancy for boys. We will recruit 50 school and undertake baseline surveys by March 2022; implement the intervention over the 2022–2024 school years and conduct the economic and process evaluations by July 2024; undertake follow-up surveys by December 2024; complete analyses, all patient and policy involvement and draft the study report by March 2025; and engage in knowledge exchange from December 2024.

Discussion

This trial is one of a growing number focused on whole-school approaches to public health in schools. The key scientific output will be evidence about the effectiveness, costs and potential scalability and transferability of Positive Choices.

A peer-led intervention to promote sexual health in secondary schools: the STASH feasibility study

Background

Young people report higher levels of unsafe sex and have higher rates of sexually transmitted infections than any other age group. Schools are well placed to facilitate early intervention, but more effective approaches are required. Peer-led approaches can augment school-based education, but often fail to capitalise on mechanisms of social influence. The potential of using social media in sexual health has not been tested in school settings.

Objectives

Finalise the design of the Sexually Transmitted infections And Sexual Health (STASH) intervention; assess the recruitment and retention of peer supporters, and acceptability to participants and stakeholders; assess the fidelity and reach, in addition to the barriers to and facilitators of, implementation; refine programme theory; understand the potential of social media; determine design parameters for a future randomised controlled trial, including economic evaluation; and establish whether or not progression criteria were met.

Design

This was a feasibility study comprising intervention development and refinement of the STASH pilot and non-randomised feasibility trial in six schools. Control data were provided by students in the year above the intervention group.

Setting

Secondary schools in Scotland.

Participants

Students aged 14–16 years, teachers and intervention delivery partners.

Interventions

The STASH intervention was adapted from A Stop Smoking In Schools Trial (ASSIST) (an effective peer-led smoking intervention). Based on diffusion of innovation theory, the STASH study involves peer nomination to identify the most influential students, with the aim of recruiting and training 15% of the year group as peer supporters. The peer supporters deliver sexual health messages to friends in their year group via conversations and use of Facebook (www.facebook.com; Facebook, Inc., Menlo Park, CA, USA) to share varied content from a curated set of web-based resources. Peer supporters are given support themselves via follow-up sessions and via trainer membership of Facebook groups.

Main outcome measures

The primary outcome was whether or not progression criteria were met in relation to intervention acceptability and feasibility. The study also piloted indicative primary outcomes for a full-scale evaluation.

Data sources

Peer supporter questionnaire; observations of activities; interviews with trainers, teachers, peer supporters and students; monitoring log of peer supporter activities (including on Facebook and meeting attendance); questionnaire to control year group (baseline characteristics, social networks, mediators and sexual health outcomes); baseline and follow-up questionnaire (approximately 6 months later) for intervention year group.

Results

A total of 104 students were trained as peer supporters (just over half of those nominated for the role by their peers). Role retention was very high (97%). Of 611 students completing the follow-up questionnaire, 58% reported exposure to STASH study activities. Intervention acceptability was high among students and stakeholders. Activities were delivered with good fidelity. The peer supporters were active, representative of their year group and well connected within their social network. Carefully managed social media use by peer supporters augmented conversations. A primary outcome of ‘always safer sex’ was identified, measured as no sex or always condom use for vaginal or anal sex in the last 6 months. The intervention cost £42 per student. Six progression criteria were met. A seventh criterion (regarding uptake of role by peer supporters) was not.

Limitations

Small feasibility study that cannot comment on effectiveness.

Conclusions

The STASH intervention is feasible and acceptable within the context of Scottish secondary schools. The results support continuation to a full-scale evaluation.

Future work

Small-scale improvements to the intervention, refinement to programme theory and funding sought for full-scale evaluation.

Age at first intercourse, number of partners and sexually transmitted infection prevalence among Danish, Norwegian and Swedish women: estimates and trends from nationally representative cross-sectional surveys of more than 100 000 women

INTRODUCTION

Sexual behavior at the population level impacts on public health. Recent representative sexual behavior data are lacking.

MATERIAL AND METHODS

Cross-sectional surveys in 2005 and 2012 on women age 18-45 years randomly selected from the general population in Denmark (n = 40 804), Norway (n = 30 331) and Sweden (n = 32 114).

RESULTS

Median (interquartile range) age at first intercourse was 16 (15-18) years in Denmark, 17 (16-18) years in Norway, and 17 (15-18) years in Sweden. Women in the most recent birth cohort had sexual debut at the lowest age, and were most likely to have sexual debut before the legal age of consent. Proportions with debut age ≤14 years among women born 1989-1994 vs 1971-1976, odds ratio (95% confidence interval) were: 18.4% vs 10.9%, 1.95 (1.74-2.18) in Denmark, 12.9% vs 6.3%, 2.38 (2.01-2.82) in Norway, 17.8% vs 11.4%, 1.75 (1.55-1.98) in Sweden. Median (interquartile range) number of lifetime sexual partners was 6 (3-10) in Denmark, 5 (2-10) in Norway, and 6 (3-11) in Sweden. The proportion of women reporting >10 sexual partners was also highest in the most recent survey. The percentage with odds ratio (95% confidence interval) in 2012 vs 2005 surveys were: 24.9% vs 22.8%, 1.13 (1.07-1.18) for Denmark; 23.8% vs 19.8%, 1.27 (1.19-1.34) for Norway; and 28.3% vs 23.8%, 1.31 (1.24-1.38) for Sweden. Similarly, the proportion of women reporting ever having had a sexually transmitted infection among women age <30 years were: 29.4% vs 26.4%, 1.21 (1.13-1.31) in Denmark, 28.9% vs 25.0%, 1.20 (1.10-1.31) in Norway, and 29.4% vs 22.2%, 1.45 (1.33-1.58) in Sweden.

CONCLUSIONS

Scandinavian women reported lower age at first intercourse in younger birth cohorts. Moreover, they reported more lifetime sexual partners and a higher prevalence of ever having a sexually transmitted infection in 2012 than in 2005. Our findings may inform the interpretation of trends in outcomes associated with sexual health, and public health policies.

Partnered Intimate Activities in Early Adolescence-Findings From the UK Millennium Cohort Study

PURPOSE

Little is known about potential influences on emerging partnered intimate behaviors in early adolescence. We investigate (1) the prevalence of partnered intimate activities and (2) associations with social relationships, parental monitoring and supervision, health behaviors, and psychosocial well-being.

METHODS

We used population-based data from the UK's Millennium Cohort Study on 11,079 participants aged 14 years. Partnered intimate activities were grouped into three categories: "light" (handholding, kissing, and cuddling); "moderate" (touching and fondling under clothes); and "heavy" (oral sex and sexual intercourse). Multinomial logistic regression models were used.

RESULTS

Thirty percent of study participants reported not engaging in partnered intimate activity. Fifty-eight percent reported "light," 7.5 percent "moderate," and 3.2 percent "heavy" activity. Associated with increased likelihood (adjusted relative risk ratios [RRRs]) of intimate activities were confiding worries in a friend (light RRR = 2.13, moderate RRR = 3.42, heavy RRR=5.32), low parental monitoring-staying out late or overnight (late: light RRR = 1.62, moderate RRR = 2.44, heavy RRR = 2.32; overnight: light RRR = 1.57, moderate RRR = 1.94, heavy RRR = 3.38), health-damaging behaviors (per unit increase: light RRR = 1.91, moderate RRR = 3.15, heavy RRR = 5.03), and depressive symptoms (per scale point increase light RRR = 1.03, moderate RRR = 1.09, heavy RRR = 1.11). Confiding in a parent was associated with lower likelihood of intimate activity (light RRR = .82, moderate RRR = .65, heavy RRR = .65).

CONCLUSIONS

Partnered intimate activity of some form is commonplace among 14-year-olds in the United Kingdom. Given the short- and long-term implications of adolescent sexual development and well-being, improving our understanding of influences could help identify opportunities for interventions with benefits across the lifecourse.
