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.

Drivers for low-acuity pediatric emergency department visits in two tertiary hospitals in Switzerland: a cross-sectional, questionnaire-based study.

PURPOSE: Low-acuity pediatric emergency department (PED) visits are frequent in high-income countries and have a negative impact on patient care at the individual and health system levels. Knowing what drives low-acuity PED visits is crucial to inform adaptations in health care delivery. We aimed to identify factors associated with low-acuity PED visits in Switzerland, including socioeconomic status, demographic features, and medical resources of families. METHODS: We conducted a prospective, questionnaire-based study in the PEDs of two Swiss tertiary care hospitals, Bern and Lausanne. We invited all consecutive children and their caregiver attending the PED during data collection times representative of the overall PED consultation structure (e.g. day/night, weekdays/weekends) to complete a questionnaire on demographic features, socioeconomic status, and medical resources. We collected medical and administrative data about the visit and defined low-acuity visits as those meeting all of the following criteria: (1) triage category 4 or 5 on the Australasian Triage Scale, (2) no imaging or laboratory test performed, and (3) discharge home. We used a binary multiple logistic regression model to identify factors associated with low-acuity visits. RESULTS: We analysed 778 PED visits (September 2019 to July 2020). Most children visiting our PEDs had a designated primary care provider (92%), with only 6% not having seen them during the last year. Fifty-five per cent of caregivers had asked for medical advice before coming to the PED. The proportion of low-acuity visits was 58%. Low-acuity visits were associated with caregiver's difficulties paying bills (aOR 2.6, 95% CI 1.6 - 4.4), having already visited a PED in the last 6 months (aOR 1.7, 95% CI 1.1 - 2.5) but not with parental education status, nor parental country of birth, parental employment status or absence of family network. CONCLUSION: Economic precariousness is an important driver for low-acuity PED visits in Switzerland, a high-income country with compulsory health coverage where most children have a designated primary care provider and a regular pediatric follow-up. Primary care providers and PEDs should screen families for economic precariousness and offer anticipatory guidance and connect those in financial need to social support.

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.

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.

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.

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.

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.

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.

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.

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.

Does regretting first vaginal intercourse have an effect on young adults' sexual behaviour?

Background The aims of this research were to determine personal differences depending on the reason for regretting or not first vaginal intercourse and its effects on sexual behaviour later on among young adults, and to assess the association between reasons for engaging in first vaginal intercourse and regretting it. METHODS: Data were drawn from the 2017 Swiss national survey on youth sexual behaviours among young adults (mean age 26 years) living in Switzerland. Out of the 7142 participants, 4793 (51% females) answered the question 'Looking back now to the first time you had vaginal intercourse, do you think that…' with five possible answers: (1) I should not have done it (6.7%); (2) I should have waited longer (7.7%); (3) I should have done it earlier (7.4%); (4) It was about the right time (67.9%); and (5) I don't know (10.3%). The five groups were compared on sociodemographic and sex behaviour-related variables, analysed separately by gender. RESULTS: One-third of participants regretted their first experience. In the multivariate analysis, compared with the 'right time' group, all other groups were more likely to find their first experience unpleasant and to have done it with a casual partner. Those in the 'I should not have done it' and 'I should have waited longer' groups were also more likely to have done it because of external pressure, especially among females. CONCLUSIONS: The study results underline the significance to choose the right time and the right partner for first vaginal intercourse and the importance of including partner respect and avoiding external pressure as part of sexual education.

"When It Deviates It Becomes Harassment, Doesn't It?" A Qualitative Study on the Definition of Sexting According to Adolescents and Young Adults, Parents, and Teachers.

Sexting was originally made public by dramatic consequences involving youths with contents that were disseminated and then used as a base for harassment. Despite a growing public and research interest, there is no consensus regarding its definition and measurements. As part of a larger qualitative study on sexting, we aimed to gather and compare opinions and perceptions of 32 youths (16-21 years) and 29 adults (11 parents and 18 teachers) on how sexting can be defined. Different constituent elements were discussed in terms of knowledge, mediums (text-only, photographs, videos, etc.), characteristics, actions (receiving, sending, disseminating, etc.) and contexts. The knowledge and the use of the term sexting was approximate for several participants. Youths used more suggestive elements in their definition and the vast majority of them defined sexting as an activity that could be positive and respectful between two consenting persons. It is necessary to develop a precise and consensual definition of sexting by separating different dimensions and by using a specific vocabulary according to youth perceptions as their main definition of sexting seems to be different from the one of most adults. Prevention messages should aim to reduce the risks by targeting the problems linked to sexting rather than prohibiting sexting per se. This exploratory study could pave the way for a clearer definition and measurement of sexting.

Protocol of a longitudinal study on the specific needs of Syrian refugee families in Switzerland.

BACKGROUND: The ongoing Syrian civil war has led to massive population displacements, leading to the reorganization of the asylum policies of several countries. Accordingly, like other European countries, the Swiss government has recently chosen to implement a specific resettlement program. This program is characterized by the fact that the whole nuclear family is granted a work and residence permit upon arrival, and benefits from enhanced integration services. The aim of the present project is to evaluate the effects of the Swiss resettlement program, with a special focus on mental health, while adopting a family perspective. METHODS: The outcomes of 15 Syrian families taking part in this program will be compared to those of 15 Syrian families that came to Switzerland through other means (i.e., following the usual asylum procedure, which is much more stressful and time consuming). Each family member above 8 years old will be invited to participate to a 3-wave longitudinal survey concerning the resettlement process: upon arrival in the collective shelters, six and 12 months later. Questionnaires will be used for the evaluation of participants' mental health, risk behaviors, general health, romantic relationship, parent-child relationship, family functioning, parentification, social support, and social identities related to group belongingness. DISCUSSION: The findings of the present project will provide longitudinal information on Syrian refugees. A comprehensive approach will be adopted by screening potential difficulties that the sample may be faced with and potential strengths that participants may rely on. Accordingly, physical and mental health, as well as the quality of family functioning, the feeling of support and of belongingness to different groups will be evaluated. We will also compare the results of families who had the chance to immigrate through the Swiss resettlement program, to the results of families that did not. This comparison will allow the elaboration of hypotheses regarding adjusted asylum policies. Furthermore, it will enhance our knowledge regarding the impact of displacement on the family system. Indeed, although the role of the family for the well-being of adults and children has been established, surprisingly few studies have adopted this focus in the asylum field.

Daily internet time: towards an evidence-based recommendation?

Background: Since 2001, a recommendation of no more than 2 h per day of screen time for children 2 years of age or older was adopted in many countries. However, this recommendation was rarely examined empirically. The goal of the present study was to question this recommendation in today's connected world. Methods: We used data from the ado@internet.ch survey (spring 2012), a representative sample of 8th graders in the Canton of Vaud, Switzerland (n = 2942, 50.6% female). Internet use, health outcomes, substance use, well-being and socio-demographic characteristics were considered. Bi-variate statistical analyses were performed. Results: All outcomes were significantly associated with the time spent on internet, more time being associated with a higher prevalence of adverse consequences. Youth spending on average one more hour on Internet per day than the reference category (1.5-2.5 h) did not differ in terms of adverse health outcomes. Differences began to appear on sleeping problems, tobacco use, alcohol misuse, cannabis use and sport inactivity with youth spending between 3.5 h and 4.5 h per day on internet. Conclusions: This study demonstrates the absence of justification for setting a limit to only 2 h of screen time per day. Significant effects on health seem to appear only beyond 4 h per day and there may be benefits for those who spend less than an hour and a half on internet.

Disordered Eating: The Young Male Side.

Disordered eating (DE) is known to predominate among girls, and historically studies have focused primarily on them. This cross-sectional study aimed to investigate the characteristics of adolescent and young adult males at risk of DE. Participants (N = 2269; 15-24 years) in a study assessing their lifestyle were divided into two groups based on the SCOFF five-question screening tool: a SCOFF[+] group for participants at risk of disordered eating, and a SCOFF[-] group for everyone else. SCOFF[+] participants were more likely to be overweight and obese; have a lower socio-economic status and non-Swiss parents; experience weight issues; and report a chronic condition, poorer emotional well-being and a less positive attitude towards life. With 10% of males at risk of DE, clinicians should be aware of their specific characteristics, which should be considered red flags. DE is no longer a female-specific issue.

Adolescents with a smartphone sleep less than their peers.

Many studies have shown that the use of electronic media is related to sleep disturbance, but few have examined the impact of smartphones. The objective of this study was to assess longitudinally whether acquiring a smartphone had an effect on adolescents' sleeping duration. The study included 591 adolescents observed at baseline (T0, Spring 2012; mean age 14.3 years, 288 females) and 2 years later (T1). They were divided into owners (those owning a smartphone at T0 and T1; N = 383), new owners (those owning a smartphone at T1 but not at T0; N = 153), and non-owners (those not owning a smartphone at any time-point; N = 55). Groups were compared on sleep duration, sleep problems, and sociodemographic variables. Overall, all three groups decreased their sleeping time between T0 and T1. At T0, owners of a smartphone were found to sleep significantly less than non-owners and new-owners, especially on school days, and to report significantly more sleeping problems. At T1, new-owners and owners showed no differences on sleep duration or sleeping problems. CONCLUSION: The results emphasize that owning a smartphone tends to entail sleep disturbance. Therefore, adolescents and parents should be informed about the potential consequences of smartphone use on sleep and health. What is Known: • The use of electronic media plays an important role in the life of adolescents. • Smartphone use is increasing among young people and allows them to be connected almost anytime anywhere. What is New : • Adolescents owning a smartphone sleep less hours on school days than their peers. • Smartphones seem to have an important impact on youths' sleep duration.

Adolescents and young adults' perceptions of electronic cigarettes as a gateway to smoking: a qualitative study in Switzerland.

Electronic cigarettes (ECs) acting as a gateway to smoking traditional cigarettes (TCs) is a growing public health concern of EC use among youths. To gather the opinions and perceptions of adolescents and young adults (AYAs) on whether and how EC can act as a gateway to smoking TC among youths. A qualitative method included 42 AYAs. Participants identified a significant risk of EC acting as a gateway to TC use, several factors contributing to this phenomenon such as a facilitated transition to smoking or its perception as a harmless toy. Participants considered an even greater gateway threat regarding very young adolescents. A minority did not identify the gateway risk and some believed that it was nicotine-dependent. This potential gateway effect brought forth several recommendations: health professionals should screen adolescents (even very young ones) for EC use and inform consumers of the potential gateway effect; this possible effect should be acknowledged to end the harmless perception many might have; there is an urge for better preventive and regulatory policies directed at protecting adolescents and children who never smoked and support those who have quit.

Consuming energy drinks at the age of 14 predicted legal and illegal substance use at 16.

AIM: This study examined whether consuming energy drinks at the age of 14 predicted substance use at 16. METHODS: We followed 621 youths from an area of Switzerland who completed a longitudinal online survey in both 2012 and 2014 when they were 14 and 16 years of age. At 14, participants, who were divided into nonenergy drink users (n = 262), occasional users (n = 183) and regular users (n = 176), reported demographic, health-related and substance use data. Substance use at 16 was assessed through logistic regression using nonusers as the reference group and controlling for significant variables at 14. RESULTS: At the bivariate level, energy drink consumption was associated with substance use at both 14 and 16. Energy drink consumers were also more likely to be male, older, less academic, sleep less on schooldays and live in an urban area. In the multivariate analysis, smokers, alcohol misusers and cannabis users at the age of 16 were significantly more likely to have been regular energy drink users at the age of 14. CONCLUSION: Consuming energy drinks at 14 years of age predicted using legal and illegal substances at 16. Health providers should screen young adolescents for energy drink use and closely monitor weekly users.

What keeps female problematic Internet users busy online?

UNLABELLED: While problematic Internet use is recognized to be predominant among male adolescents, a female trend is gradually becoming apparent. Our study aimed at investigating the characteristics of female Internet users and distinguishing between the online activities of problematic and regular Internet users' on school days. Data were retrieved from a cross-sectional survey of a representative sample of 3067 8th graders in the canton of Vaud, Switzerland, that completed an online questionnaire in 2012. Only females were included. Based on the Internet addiction test, the sample was divided into regular (RUs) (IAT < 50, n = 1339) and problematic users (PIUs) (IAT ≥ 50, n = 201). Groups were compared regarding sociodemographic variables, online activities, devices used to access the Internet, substance use, and physical activity. Significant variables were included in a backward logistic regression. At the multivariate level, PIUs were more prone to spend time online for leisure activities (odds ratio [OR] 2.38) and to access the Internet through a smartphone (OR 1.79) or tablet (OR 1.84). PIUs were less likely to be physically active (OR 0.86) and more likely to present poor emotional well-being (OR 2.67) and to smoke (OR 1.88). CONCLUSION: A sizeable percentage of female adolescents are problematic Internet users. When performing a comprehensive biopsychosocial assessment, teenagers owning numerous devices to access the Internet, presenting other health-compromising behaviors or poor emotional well-being should be specifically targeted.

Problematic Internet use is associated with substance use in young adolescents.

AIM: This study examined whether problematic Internet use was associated with substance use among young adolescents and assessed whether this association accounted for the use of tobacco, alcohol, cannabis and other drugs. METHODS: Using the Internet Addiction Test, we divided a representative sample of 3067 adolescents in Switzerland (mean age 14 years) into regular and problematic Internet users. We performed a bivariate analysis and two logistic regression models, to analyse substances separately and simultaneously, and developed a log-linear model to define the associations between significant variables. RESULTS: Problematic Internet users were more likely to be female, to use substances, to come from nonintact families, to report poor emotional well-being and to be below average students. The first model showed significant associations between problematic users and each substance, with adjusted odds ratios of 2.05 for tobacco, 1.72 for alcohol, 1.94 for cannabis and 2.73 for other drugs. Only smoking remained significant in the second model, with an adjusted odds ratio of 1.71. CONCLUSION: Problematic Internet use is associated with other risky behaviours and may be an important early predictor of adolescent substance use. Therefore, it should be included in the psychosocial screening of adolescents.
