Prospective prediction of alcohol consumption among a Tunisian sample of adolescents

Abstract Background During adolescence, alcohol consumption represents a new experience with the advantage of facilitating the integration of a peer group. The global overall prevalence of this risk behavior among the 15-19 years old was over 25% in 2018. However, this prevalence varies between countries. Objectives To determine the incidence and the predictors of alcohol consumption among high school students in Sousse, Tunisia between 2017/2018 and 2018/2019. Methods A prospective longitudinal study was conducted in four high schools in the governorate of Sousse during the 2018-2019 school year. Pre-trained medical doctors used an anonymous self-administered questionnaire to collect data about socio-demographic and educational features, alcohol consumption, tobacco use, illicit substances use and emotional disorders. Results Participants accounted for 404. Their average age was 16.4 (±1.1) years. Females represented 68%. The prevalence of alcohol consumption in 2017/2018 was 5.9% while the cumulative incidence during the 2018/2019 school year was 3.5%. Among males, this incidence was of 11.9%. Among females, it was of 3% (p = 0.020). Illicit substance use among friends was the main predictor of becoming alcohol consumer with an adjusted odds ratio of 6.4 (95% CI: 1.9-21.3) on the other hand, having an anxiety trouble predicted less this risk behavior (adjusted odds ratio =0.2 95% CI: 0.1-0.8). Conclusions Alcohol consumption is becoming more and more common among the adolescents of Sousse especially among males. The current national strategy against substances use in schools should be reinforced. Implementation of a social skills training among adolescents to improve assertiveness is essential. Key messages • Alcohol consumption has an upword trend among the adolescents of Sousse. • The current prevention programs targetting adolescents in Tunisia should be revised and integrate a comprehensive and multisectoral program.


Background:
Exposome research looks into how combined exposures affect human health. The EU-funded Equal-Life project focuses on physical and social exposures in a child's environment and its effects on children's mental health and cognitive development in the life course. Perspectives and priorities on what to study in particular might differ between practitioners and researchers. Therefore, collaboration with external stakeholders from various fields is encouraged to integrate practical experience and link it to the researchers' aims.

Methods:
Two Delphi studies were conducted collecting and evaluating research questions to be studied in the project among a) the researchers within the project and b) among external stakeholders from various European countries. The exercise was to evaluate the research questions for group a) based on relevance and testability and for b) e.g. regarding practitioners' work and options for policies. Involved stakeholders work in health care, and urban planning, among others. Prioritised questions are collated.

Findings:
Within the researchers' group, top-rated questions were mainly mechanism-directed in terms of how and to what extent certain factors affect children's mental health and cognitive development, cumulative effects in different settings, among others. Stakeholders most value research questions on practical issues, e.g. effects of early experiences of discrimination, critical windows in children's lives that are most sensitive regarding the impact of exposures on mental health and cognitive development, or impact of exposures in early stages of life.

Discussion:
In comparing approaches of stakeholders and researchers, stakeholders' input from the practical field can shape the approach of the research process. The second benefit is to derive implications for creating effective interventions and policies to prevent adverse effects of environmental exposures and to foster positive health in children and later on in life.

Key messages:
Bi-directional exchange between researchers and external stakeholders can make gaps visible. Engaging stakeholders into a research process can help sharpening the aim and outcome of a project. 5%. Among males, this incidence was of 11.9%. Among females, it was of 3% (p = 0.020).

Conclusions:
Alcohol consumption is becoming more and more common among the adolescents of Sousse especially among males. The current national strategy against substances use in schools should be reinforced. Implementation of a social skills training among adolescents to improve assertiveness is essential. Key messages: Alcohol consumption has an upword trend among the adolescents of Sousse. The current prevention programs targetting adolescents in Tunisia should be revised and integrate a comprehensive and multisectoral program.

Background:
School years are crucial for acquiring life-lasting healthy habits. However, an increasing rate of children and adolescents fail to maintain a healthy lifestyle. European Union has financed the Erasmus+ Sport Let's Move Europa project to design an innovative digital tool for promoting healthy lifestyles among those age groups. University of Bologna, partner of the project, has developed 30 Learning Units (LUs) about Physical Activity, Sleep and Nutrition to be integrated in the school program by teachers.

Methods:
A group of 17 teachers (15 females and 2 males, mean SD age 49,5 AE11,6) from primary and secondary schools located in Bologna province (Italy) took part in semi-structured focus groups (FGs). The investigation focused on facilitators/barriers of the intervention and possible solutions, identifying time frames and locations, suggestions for engaging the different stakeholders (teachers, students and families). All FGs were recorded, transcribed, anonymized, and analyzed through inductive thematic analysis.

Results:
30 LUs were created based on the latest scientific evidence and the FGs output. Each LU addresses a specific topic and is tailored differently for primary and secondary school. The layout includes an investigation on the topic, classroom activities, and a section about ''healthy homework'' or ''challenges'' to be accomplished at home, engaging families in the construction of a healthy routine. All the activities were designed to be feasible and sustainable. Each LU includes a discussion phase to understand students' feedback about proposed homework and learning content.

Conclusions:
FGs have proven crucial to tailoring LUs on the needs of different stakeholders and co-designing an effective intervention. ''Healthy homework'' and ''Challenges'' encourage students to pursue healthy habits also outside the school setting, involving families. Feedback on the activity provides an insight into the progression and effectiveness of the intervention.
Key messages: The EUmove project integrates knowledge about sleeping, nutritional and physical activity habits into the school curriculum to promote healthy lifestyles among students and their families. Thanks to the FGs, LUs are designed to suit the target audience. LUs integration into school curricula is therefore a feasible intervention, not requiring specialized personnel to be implemented.
