Characteristics of Young People Reporting a Low Sexual Desire in Switzerland.

This study explores the characteristics of young female and male adults (mean age 26.3 years) reporting a low sexual desire. A 2017 Swiss national survey was carried out among young adults. Participants were divided into two groups based on their level of sexual desire: Low and High. Overall, 17.2% of females and 5.7% of males reported a low sexual desire. At the multivariate level, compared to females in the High group, females in the Low group had higher odds of being dissatisfied with their social life and with their sexual life in the past 4 weeks, having no current relationship and having accepted several times sexual intercourse without really wanting. Compared to males in the High group, males in the Low group had higher odds of reporting a non-heterosexual attraction (trend), having no current relationship and having accepted several times sexual intercourse without really wanting. The prevailing idea that young people, particularly males, always have high levels of sexual desire may not be accurate and warrants further consideration. These results show that sexual desire encompasses social aspects and underscore importance of addressing how stereotypes and social norms may influence our sexuality.

[Screens and adolescence: what issues for the Z generation?] / Écrans et adolescence : quels enjeux pour la Génération Z ?

Digital media and screens are ubiquitous in the daily lives of adolescents. The screen-addicted portrait of young people has gained public attention, and health professionals are often consulted about the impact of screen use on teenagers' physical and mental health. Scientific evidence suggests that screen use is associated with risks and benefits that need to be weighed up in a nuanced way. This paper takes a critical look at the issue of screen time and at the models for understanding a problematic screen use. These considerations underline the importance of adopting a contextual understanding of screen use in adolescence.

Les médias numériques sont omniprésents dans la vie quotidienne des adolescent-es. La figure de l'adolescent-e « addict-e ¼ aux écrans est devenue un sujet de préoccupation dans l'opinion publique et il est fréquent que les professionnel-les de la santé soient sollicité-es pour répondre aux interrogations sur l'impact de l'utilisation des écrans sur la santé mentale et physique des jeunes. Les données scientifiques indiquent que l'usage des écrans est associé à des risques et des bénéfices qu'il s'agit d'évaluer de manière nuancée. Dans cet article, nous discutons en particulier et de façon critique du temps d'écran et des modèles de compréhension de l'usage problématique de celui-ci. Ces réflexions nous amènent à souligner l'importance d'adopter une compréhension contextualisée de cet usage à l'adolescence.

Adolescent behavioural risk screening in primary care: physician's point of view.

BACKGROUND: Despite regular consultation between adolescents/young adults (AYA) and their physicians, they are not regularly screened for psychosocial risk behaviours. This study examines physicians' self-reported psychosocial risk behaviour screening in AYA. It aims to highlight which elements hinder or improve screening abilities. METHODOLOGY: The design was a cross-sectional quantitative survey. Data were obtained through a self-reported questionnaire sent out to primary care physicians (PCP) in Switzerland in 2018. The target population consisted of 1,824 PCP (29% response rate). Participants were asked whether they screened youths from 3 age groups [10-14 y/o, 15-20 y/o, and 21-25y/o] for the HEEADSSS items during child well visits and routine checkups. Barriers to screening included primary consultation motive prioritization, insufficient time, patient compliance, reimbursement, lack of skills related to adolescent health, lack of referral options. Data were analysed first through a bivariate analysis using Chi-square tests then through a multinomial logistic regression. RESULTS: The majority of physicians partook in preventive screening for 3-5 psychosocial risk elements. They reported the primary consultation motive as well as a lack of available time as having a high impact on their screening habits. Physician's experience and having discussed confidentiality were related to an increase in the number of topics addressed. Confidentiality remained a significant variable throughout all analyses. CONCLUSION: Barriers such as lack of consultation time and prioritization issues were found by physicians to be critical but did not hinder screening habits. The main element impacting screening habits was assuring confidentiality and the second is self-efficacy.

Evolution of screen use among youth between 2012 and 2020 in Switzerland.

AIM: To compare the evolution of screen and Internet use by youths between 2012 and 2020 in Switzerland. METHODS: Cross-sectional studies of 10th-graders (age 13-14) were performed in Switzerland in 2012 and 2020, and compared in bivariate and multivariate analyses on sociodemographic, schooling, physical activity, emotional well-being, and screen use variables. RESULTS: We found that screen use had shifted to smartphones with 71.7 % of youths primarily using this device in 2020 compared to 23.2 % in 2012. In association with this change, young people's screen time had increased dramatically with an odds ratio (OR) of 11.90 for adolescents spending more than 4 h in front of screens in 2020 compared to 2012. No changes were found in the score on the Internet Addiction Test (IAT) to detect problematic screen use and for adolescents' emotional well-being. Furthermore, youths in 2020 engaged in less physical activity lasting 60 min daily, but the frequency of their extracurricular sport participation remained unchanged. CONCLUSIONS: Young people spend more time on screens, especially because of an increase in smartphone use in 2020. However, youths do not seem to show more problematic behaviors regarding screen use, nor has this development affected their emotional well-being. The daily and continuous use of new devices is now an integral part of young people's lives. This process seems to be part of the growth of the digital world. However, Internet and screen addiction scales should be adapted to ensure that adolescents in need of help and counseling are identified.

Parents, teens and screens during COVID-19 containment: An exploratory study.

OBJECTIVE: One of the main concerns of parents is the amount of screen time of their teenagers, and most of them try to set rules about it. The objective of this exploratory study was to compare whether parents' rules changed during confinement and whether these changes were successful. METHODS: We studied a group of parents (N = 47) of 13-year-olds in Switzerland surveyed before and during the COVID-19 pandemic. RESULTS: Most parents (83%) indicated that screen-time rules for their teens had changed during containment, mainly to be less strict. Although only a minority of parents were successful in defining screen-time spaces or schedules for their teenagers, almost three out of four were successful when they encouraged non-screen-based activities. CONCLUSIONS: This exploratory study reveals that, during containment, parents decided to be less strict with their teens' screen-time use even though it remained their main worry. However, it also suggests that when activities non-involving screens are proposed, teens are likely to participate. These results seem to indicate that reducing screen time is not a matter of imposing restrictions but, rather, of proposing alternatives. Finally, further research is warranted to assess whether these changes in screen-time use are exceptional or here to stay.

The Growing Trend of Young People Abstaining from Drinking Alcohol: A Literature Review.

Background: Youth alcohol use and misuse lead to adverse outcomes. However, the literature has not always associated complete abstinence with better health. Since recent literature indicates an increased proportion of young abstainers, the aim of this paper is to review the studies investigating this upward trend and the factors associated with it, such as socio-demographics, school performance, social life, physical and mental health, and parental influence. Methods: Different databases were searched and appropriated terms were used. Given that the trend has only emerged in recent years, the review was limited to papers published since 2000. A total of 970 papers were returned and 10 were retained for the present review. Results: All papers covered by the review acknowledge the existence of a new significant trend resulting in more young people in developed countries who are choosing to abstain completely from drinking alcohol. They are in good physical and mental health and perform better at school than their drinking peers. The quality of their social life, albeit slightly more limited than that of their drinking peers, appeared to be good. Conclusion: Young alcohol abstainers represent a group situated at the beginning of a continuum of alcohol consumption, they do well and are not very different from light drinkers. Alcohol abstinence at young age does not seem to have any downsides and should therefore be generally advised. To further promote such behavior, measures to encourage parental monitoring and more generous public expenditure on health services and family benefits should be encouraged.

From request to dispensation: how adolescent and young adult females experience access to emergency contraception in pharmacies.

PURPOSE: Emergency contraception (EC) access was liberalised in 2002 in Switzerland by making it accessible in pharmacies without medical prescription. However, its dispensation still requires a confidential interview with a pharmacist. This qualitative study aims to explore experiences of adolescent and young adult (AYA) females who have gone to a pharmacy in order to obtain EC. MATERIALS AND METHODS: Thirty interviews were conducted from April to August 2019 with females aged between 15 and 25 years old at the interview. Inclusion criteria was to have requested at least one EC in a pharmacy between 2014 and 2019. A thematic content analysis was performed to extract themes brought up by the participants. RESULTS: Some participants reported that the most difficult moment in the process was the request at the counter. The majority of participants were escorted in a private back room but opinions were divided regarding this isolation. Experiences were sometimes negative due to lack of information and knowledge regarding the dispensation process. The interview also has also a preventive aim, but the information given during it often focussed solely on the risk of vomiting. Several participants reported having perceived or received moral judgements from pharmacists. CONCLUSIONS: Pharmacists are key resources and EC dispensation an opportunity for sexual health. This exploratory study presents several elements requiring the adaptation of practices in order to prevent them from becoming barriers for AYA to access EC. Concerns are regularly expressed by young women about privacy, embarrassment and judgement in the pharmacy context regarding contraception.

Sending One's Own Intimate Image: Sexting Among Middle-School Teens.

BACKGROUND: There is a gap in the literature regarding data on sexting among youth under the age of 16 whereas the problems related to this practice could affect them more because of their ongoing development. This study aims to determine the prevalence rate and characteristics of sending one's own sexually related image among middle-school teens. METHODS: Data were obtained from a web-based in-school survey conducted between October 2019 and February 2020. The sample comprised 3006 (mean age 13.7; 50.2% males) 10th-grade pupils in the canton of Vaud (Switzerland). Participants were asked "Have you ever sent a sexually related/sexy image of yourself?". Analysis of variance/chi-square tests and multinomial regression analyses were used to compare the groups. RESULTS: Overall, 93.0% reported never, 3.7% once and 3.3% several times. No gender differences were found. Sending was associated with older age, low academic performance, cyberbullying victimization and reception of unsolicited sexually related images. CONCLUSIONS: Education and health professionals should be aware that it is necessary to discuss the theme, perhaps with a more global approach including pressure, consent, exchange of nonsexual images, and so on from an early age. The context and reasons for sending remain to be explored, particularly to determine if the pressure is greater at this age.

Understanding Sexual Health Indicators During Adolescence: A Study to Consider Time Since Sexual Debut When Exploring Multiple Sexual Partners.

Understanding risky sexual behaviors among adolescents is key in efforts devoted to reducing the health burden related to sexually transmitted infections and unintended or unplanned pregnancies. The aims of this study were to understand the association between number of lifetime sexual partners and time since sexual debut (TSSD) among adolescents and to determine whether sex modified this association. Data were drawn from the 2018-2019 COMPASS-Quebec study, a cohort study conducted in secondary schools in the province of Quebec, Canada. Of 18,467 respondents aged 14 years and older, 6991 (37.9%; mean age 15.3) reported consensual sexual intercourse and answered questions on their age at sexual initiation and number of lifetime sexual partners. Multilevel Poisson regressions with robust standard errors were estimated to adjust for covariates and produce adjusted group mean differences. The adjusted mean number of lifetime sexual partners ranged from 1.5 for those who had recently begun sexual activity (< 12 months) to 4.0 for those who had been active for > 35 months, an average rise of about 0.6 per year. Females-to-males adjusted mean differences showed that males reported more sexual partners than females at all time points, but the differences were only significant at the shorter (< 12 months) and longer (> 35 months) time spans. This study highlights the importance of taking into account TSSD when using and interpreting the number of lifetime sexual partners as risky sexual behavior among adolescents. Sex did not have a significant modifying effect on the relationship between number of lifetime sexual partners and TSSD.

Transactional sex among young people in Switzerland: a cross-sectional study.

Background The aim of this research was to determine the prevalence and characteristics of youths having ever exchanged sex and to assess if there were differences depending on whether they had done it once or several times. We also investigated what they exchanged sex for and their relationship with the last person they did it with. Methods A cross-sectional national survey was carried out in Switzerland in 2017 among young adults. The 5175 participants (51% males, mean age 26.3years) who answered the question 'Have you ever received something or obtained an advantage in exchange for a sexual act?' were divided into three groups: Never (96.8%), Once (1.5%) and Several (1.7%). Results In the multivariate analysis, compared to the Never group, those in the Once group were significantly more likely to be males, to have a poor mental health, to be non-exclusively heterosexual and to have had 10+ lifetime sexual partners. Those in the Several group reported the same characteristics, but were also more likely to be younger at first sexual contact, to have their parents not living together, to report a lower socioeconomic status and a history of sexual abuse, and to have ever sent sexual images/videos of themselves. They were also less satisfied with their financial situation. Conclusions Results indicate that transactional sex is a reality for some youths in Switzerland, and health professionals dealing with them should include this question in their sexual anamnesis. From a public health perspective, sexual education and prevention campaigns should include this phenomenon.

Transition from paediatric to adult care: What about the healthy ones?

OBJECTIVE: To compare the characteristics of and use of the healthcare system by healthy youths depending on whether they had discussed transition to adult health care with their paediatrician or not. METHODS: Data were drawn from the fourth wave of the GenerationFRee study (2018-2019) conducted in the 11 post-mandatory schools of the canton of Fribourg, Switzerland. The sample included 931 young people (mean age 19.4 years). Participants were categorised into three groups: those who had discussed transition with their p ediatrician (n = 176; 19%), those who had not (n = 286; 31%) and those who did not know (n = 469; 50%). Analyses were stratified by gender through bivariate analysis and post-hoc tests with a Bonferroni-type adjustment. RESULTS: The majority of participants did not know whether or not they had discussed transition. Across all groups, it was found that youths met their primary care physician at a higher rate through family. Meeting with the primary care physician through the paediatrician occurred at a higher rate when youths had discussed transition. Girls with a below average socioeconomic status and boys with advanced puberty onset were more likely to have discussed transition. CONCLUSION: Our results show that youths are not well informed about the transition process. However, youths who have discussed transition appear to be more involved with the healthcare system as they are more likely to have a primary care provider. In order to avoid discontinuity of care, professionals should approach transition to adult care systematically with all their patients.

Virgins at age 26: who are they?

Background Studies on virgins remain scarce. This study explores the characteristics of virgin young adults, the reasons for remaining virgin, and its potential social and health implications. METHODS: Data were drawn from the 2017 Swiss study on sexual health and behaviour among young adults. A total of 5175 participants (mean age 26 years ± 0.01) were divided into virgins and non-virgins. Virginity was defined as never having had a sexual partner, defined as a person with whom the participant has had sexual contact with or without penetration. RESULTS: A total of 275 (5.3% (95% CI: 4.7-6.0), 58% males) were virgins. Virgins had higher odds of being male (aOR: 2.27 (95% CI: 1.62-3.17)) and reporting poorer health (1.43 (1.07-1.92)). They had lower odds of living on their own (0.24 (0.18-0.32)), being satisfied with their social life (0.78 (0.72-0.85)), having experimented with substances (e.g. drunkenness, 0.27 (0.19-0.67)) and having used online dating (0.52 (0.26-1.12)) or pornography (0.67 (0.42-0.94)). The main reason for remaining virgin was 'I have not found the right person' for females, and 'I have not had the occasion' for males. CONCLUSIONS: Among young adults, 1 in 20 is a virgin. Virgins do not seem to have gone through the usual experimentations of adolescence, are less socially driven and reported more health challenges. The main reason for remaining a virgin reveals gender-stereotyped responses. Sexual inactivity among young adults should be considered by health professionals to ensure the absence of distress and open discussion for potential questions.

Losing your virginity safely? A Swiss national survey.

WHAT IS KNOWN ON THE SUBJECT: Good practice and knowledge in terms of contraception at first sexual intercourse may lead adolescents to a safer sexual life. To date, research studies have mostly focused on women when investigating contraception use or on condom use only when addressing both genders. WHAT DOES THIS ARTICLE ADD: The present study adds to the current knowledge by offering a more in-depth view of contraception use at first intercourse among youths. This is achieved through a large selection of variables, the fact that we address both males and females and that we have considered a wide range of contraceptive means. AIM OF THE STUDY: To determine the rate of contraception use at first intercourse by youth in Switzerland and its association with social and personal characteristics. METHODS: Data were obtained from a self-administrated national survey on sexual behaviour among young adults (mean age 26 years). Participants (n = 4036) were divided into three groups based on the means of contraception used at first intercourse: condom, with or without contraceptive (86.4%), contraceptive only (8.3%) and non-use (5.3%). RESULTS: Only 5.3% did not use any contraception. Compared with the condom group, individuals in the non-use group were more likely to report a lower family socioeconomic status, to be foreign born, to have foreign-born parents, to have a non-intact family and to live in a Catholic canton. They were also more likely to have had their first intercourse in the context of a casual relationship, to have been intoxicated at the time and more likely to regret it. Participants in the contraceptive group reported a higher family socioeconomic status, had intact families, did not live in Catholic cantons, were older and in a steady relationship at first intercourse. CONCLUSION: Contraception is generally used at first intercourse in Switzerland. Improvements can still be made concerning contraception use in the most vulnerable social strata such as low income families or foreign status.

Anal Intercourse among Heterosexual Young Adults: A Population-Based Survey in Switzerland.

Anal intercourse (AI) among heterosexuals is an understudied and taboo subject. This 2017 Swiss national study aimed to describe the characteristics and motivations of heterosexual young adults practicing AI. Participants with any same-sex experience, same-sex attraction or non-heterosexual identity were excluded. The Federal Statistical Office provided the initial sample and potential participants were recruited through postal mail inviting them to an online survey (response rate 15.1%). The sample comprised 3892 participants (52% males; 54% of the overall sample, mean age 26.3 years). Overall, 55% of women and 56% of men had never experienced AI, 17% and 12% had done it once and 28% and 32% more than once, respectively. We found that participants engaging in AI had higher odds of practicing intercourse while intoxicated, being younger at first sexual experience, not using a condom at last intercourse and reporting a history of sexual transmitted infections. The main reason reported by both genders for engaging in their first AI was being curious followed by being in love. In conclusion, AI is a widespread practice among heterosexual young adults and health professionals should be especially attentive to it.

Siblings of youths with chronic conditions: a school-based survey.

PURPOSE: The purpose of this study was to explore the differences between youths with a sibling affected by a chronic condition or a disability (SCCD) and their peers with healthy siblings. METHOD: Using data from the second wave of GenerationFRee study, we compared adolescents from each gender with healthy siblings to adolescents with SCDD on demographical, familial, internalizing and externalizing behavior variables. Subsequently we repeated the analysis excluding from each group adolescents who suffered from a chronic condition or disability themselves. RESULTS: At the bivariate and multivariate level, among those with SCDD, healthy females reported more somatic symptoms, healthy males more violent behaviors, and both genders lived more often in non-intact families. When considering both healthy and unhealthy adolescents, at bivariate analysis female adolescents with SCDD were more likely to have a poorer relationship to their mother, to be unhealthy, to smoke, to be at risk for disordered eating and to report somatic symptoms. At multivariate level, only the association with SCDD and smoking remained. Male adolescents with SCDD, at both bivariate and multivariate analyses, were more likely to be unhealthy and to live in larger and non-intact families. CONCLUSION: Healthy adolescents with an SCDD are more at risk of somatic symptoms and violent behaviors than their peers with healthy siblings. Health professionals in contact with adolescents should always consider them with a systemic approach. Parents should be informed about the potential effect on the siblings of a CDD child, but also reassured, as adolescents with SCDD are not different from their peers with healthy siblings.

Contraception use: is everything played at first intercourse?

OBJECTIVES: The rate of condom and other contraception use varies depending on social, personal and sexual characteristics. We present a study covering various contraceptive means, considering sexual orientation and considering a large panel of co-variables among Swiss resident young adults. METHODS: Data were obtained from a self-administrated national survey on sexual behavior. Participants (N=4703, 49% males) were divided into three groups based on the mean of contraception used at last intercourse: CONDOM (55.1, 54.3% males), CONTRACEPTIVE (34.3, 43.1% males) and NON-USE (10.5, 50.7% males). By gender, groups were compared on sociodemographic and personal characteristics, contraception used at first intercourse (FI) and sexual life. RESULTS: Globally, 90% of participants used a reliable contraception at last intercourse. Compared to the CONDOM group, participants in the CONTRACEPTIVE group were more likely to have already used a contraceptive at FI, and individuals in the NON-USE group were more likely to have had a non-use or to have used a contraceptive only at FI. CONCLUSIONS: Contraception at FI seems to have a considerable impact on the further use of contraception. It seems thus essential to make all necessary efforts in order to promote the best contraception and protection at FI.

Youths and poor emotional wellbeing: is it just a matter of stress? A longitudinal survey.

WHAT IS KNOWN ON THE SUBJECT: To date, research on emotional wellbeing among youths has been mostly based on cross-sectional studies, and little is known about its evolution over time. WHAT DOES THIS ARTICLE ADD: Our study adds a longitudinal approach to emotional wellbeing and defines different groups of youths according to their evolution over a two-year period. Stress and perceived health status seem to be the most important factors related to emotional wellbeing. Our research shows the importance of health care professionals exploring psychological health, especially when a youth has atypical somatic complaints. This could allow the early detection of psychological problems and the provision of proper timely treatment. AIM OF THE STUDY: To assess how emotional wellbeing evolves over a two-year period among youths in Switzerland, and to assess their characteristics. METHODS: Data were obtained from the first and third waves of the GenerationFRee study (n = 1311, aged 15–24 at baseline). The sample was divided into four groups according to the evolution of their emotional wellbeing (WB): good at both waves (GoodWB: 67.9%), poor at T1 and good at T3 (BetterWB: 8.4%), good at T1 and poor at T3 (WorseWB: 13.2%), or poor at both waves (PoorWB: 10.4%). Significant variables at the bivariate level were included in a multinomial regression analysis using GoodWB as the reference category. Results are given as relative risk ratios (RRRs). RESULTS: The BetterWB group reported more stress at T1 (RRR 1.34), as did the WorseWB group at T3 (1.43). Those in the WorseWB group were more likely to report poorer health status at T3 (6.51). Finally, the PoorWB group reported more stress at T1 (1.33) and T3 (1.44), and poorer health status at T1 (9.39) and T3 (5.75). Other variables not significant in all groups were perceived onset of puberty, having a chronic condition, area of residence and relationships with parents. CONCLUSION: Using a longitudinal approach, stress and perceived health status seem to be the main factors that change with emotional wellbeing among youths. Inquiring about stress could be a good proxy for emotional wellbeing, especially among males, who tend to underestimate their emotional worries.

Far from acceptable: youth-reported risk behaviour screening by primary care physicians.

BACKGROUND: Adolescence and early adulthood are periods of experimentation during which health detrimental behaviours might be acquired. OBJECTIVE: This study's purpose is to evaluate physicians' likelihood of addressing health risk behaviours with youths depending on the youths' wishes, risk behaviours and personal characteristics. METHODS: Data were drawn from the third wave (2017-18) of the GenerationFRee longitudinal study carried out on a sample of 1970 youths aged 17-26 in Switzerland. Analysed risk behaviours were: eating disorders, substance use, emotional wellbeing, problematic Internet use and gambling. Bivariate and multivariate analyses were performed, results are presented as adjusted odds ratios (aORs). RESULTS: Physicians discussed most risk behaviours with less than half of the youths. The odds of addressing risk behaviours were seldom raised when the risk behaviour was present, or when the youth wished to discuss it. Emotional wellbeing was addressed with half as many males as females (aOR 0.47), and drugs were found to be addressed more frequently with youths reporting a low family socio-economic status (aOR 6.18). When a risk behaviour is addressed it is mostly alongside an extended screening. CONCLUSIONS: This study confirmed the low levels of health risk behaviours screening, regardless of the youths' wish to discuss the topic with their physician. Despite the low levels, physicians do tend to screen systematically, especially when discussing substance use. There is a need to improve physicians training in risk behaviour screening and counselling in order to increase this practice.

Characteristics defining perceived popularity among same-sex and opposite-sex peers.

OBJECTIVES: The objective of this study was to compare the characteristics of adolescents and young adults (AYA) who perceive themselves as popular with AYAs who perceive themselves as unpopular vis-á-vis peers from same-sex, opposite-sex, or both. METHODS: Among a representative sample of in-school 15-24 year-olds students (n=5,179) who completed a self-administrated questionnaire, we measured self-perception of popularity, socio-demographic data, ease to make same/opposite-sex friends, emotional well-being, school variables, substance use, sensation seeking, self-perception of pubertal timing, and aggressive/violent behavior. RESULTS: Overall, our findings put forth that popularity was associated to easiness of making same/opposite-sex friends, emotional well-being, socio-economical background, sensation seeking behaviors, and alcohol misuse. Differences appeared between males or females. CONCLUSION: Findings indicate that popularity remains a very important issue among this age group and should be a red flag in clinical assessment. Future research should explore whether feeling of unpopularity can be used as a marker of adolescent well-being and hence help identify those youths who might need help.

Non-consensual sexting: characteristics and motives of youths who share received-intimate content without consent.

Background:One of the possible negative consequences of sexting is the non-consensual sharing of received-intimate content. This study aimed to determine the characteristics and motives of youths who shared received-intimate images without consent. Methods: Data were obtained from a self-administrated Swiss survey on sexual behaviours among young adults (aged 24-26 years). Out of the 7142 participants, 5175 responded to the question 'Have you ever shared (forwarding or showing) a sexy photograph/video of someone else (known or unknown) without consent'?; 85% had never shared (Never), 6% had shared once (Once) and 9% had shared several times (Several). Data are presented as relative risk ratios with 95% confidence intervals. Results: Participants who had shared received-intimate content without consent had higher odds of being male [2.73 (2.14-3.47)], foreign-born [1.45 (1.04-2.03)], reporting a non-heterosexual orientation [1.46 (1.10-1.93)], having sent one's own intimate image [1.76 (1.32-2.34)] and receiving a shared-intimate image of someone unknown [4.56 (3.28-6.36)] or known [2.76 (1.52-5.01)] compared with participants who had never shared. The main reported motivations were for fun (62%), showing off (30%) and failure to realise what they were doing (9%). Conclusions: Given the reported motivations, it appears crucial to remind youths of the seriousness of non-consensual sharing. Although females may also be perpetrators, the behaviour was more prevalent among males. Prevention and education need to consider a broad range of young people in their scenarios. Even if a particular focus on understanding and preventing males' perpetration must be considered, overall perpetration, including female's, must be discussed.
