Health behaviours
The theme of health behaviours is part of the research of Youth Studies and is divided into four sub-themes:
Subtheme 1: Substance use
For many young people, experimenting with substances such as alcohol, tobacco, or cannabis is part of a broader search for belonging. However, early initiation can increase the risk of dependence and can negatively impact physical and mental health. By exploring the reasons for substance use and the contexts in which it occurs, we aim to better understand how to prevent harm and support healthier choices.
Subtheme 2: Sexual health
Young people often have their first sexual experiences during adolescence. These can enhance wellbeing, but they also carry risks, such as unplanned pregnancy or STIs. Supportive environments, open communication, and access to accurate information are essential in helping adolescents navigate this aspect of their lives safely and confidently. With our research, we aim to better understand which factors – at the individual, family, school and national level - positively contribute to adolescent sexual health.
Subtheme 3: Online behaviours
Online behaviours are an integral part of adolescents' daily lives. Social media and gaming offer opportunities for connection, creativity and exploration, but they also present challenges such as cyberbullying, exposure to harmful content and excessive screen time. We study why, how and in which contexts adolescents engage in specific online behaviours and how this relates to other aspects of their lives, such as social relationships and mental health.
Subtheme 4: Physical exercise and eating habits
Physical exercise and eating habits are key contributors to adolescents' overall health. During adolescence, young people begin to establish routines and preferences that are often carried into adulthood. In this process, they may face barriers such as social pressures and body ideals. Through our research, we aim to contribute to strengthening support for adolescents so they can make choices that protect their long-term health.
