Key findings from the latest international survey (2021/22): Health Behaviour in School-aged Children (HBSC) study

The Health Behaviour in School-aged Children (HBSC) study is an international research collaboration conducted with WHO/Europe. Every 4 years, HBSC surveys nationally representative samples of 11-, 13- and 15-year-olds in each participating country. The latest international report series draws on data from over 280 000 adolescents in 44 countries and regions, collected during the 2021/2022 survey round. Many findings are compared to previous HBSC surveys from 2013/2014 and 2017/2018, enabling trends to be tracked over time.

What does the data cover?

The HBSC survey collects information on physical and mental health, social relationships, risk behaviours and the environments where young people live and learn. Each volume in this series explores a different aspect of adolescent health, providing clear evidence to inform policies, programmes and services across the WHO European Region.

Overarching findings and key challenges

  • Gender gaps are widening, with girls reporting poorer outcomes in mental health, body image, substance use and digital behaviours. These gaps become more pronounced with age.
  • Socioeconomic differences are evident. Adolescents from less affluent families have consistently poorer health and well-being.
  • Many health risks, including low physical activity, substance use and problematic digital habits, begin early in adolescence.
  • Supportive families, schools and peer environments are critical, but many young people, especially girls, are experiencing less support than before.
  • There is a clear need for early, targeted interventions and action to promote health equity and address these persistent and emerging challenges.

Main findings from each HBSC international volume (2021/22)

Volume 1: Mental health and well-being

  • Gender disparities in mental health. Girls consistently report worse mental health outcomes compared to boys, with these disparities widening as they age. Notably, 28% of 15-year-old girls report feeling lonely most or all of the time, compared to 13% of boys.
  • Decline in overall adolescent well-being. Life satisfaction and self-rated health have decreased since 2018, with a sharper decline among girls​.
  • Health complaints rising. Multiple health complaints, such as headaches and sleep difficulties, are more common among girls, with prevalence increasing with age.
  • Socio-economic disparities. Adolescents from more affluent families report better mental health and life satisfaction compared to those from lower socio-economic backgrounds.

Volume 2: Bullying and cyberbullying

  • Stable school bullying trends. 11% of adolescents report being bullied at school.
  • Cyberbullying on the rise. 15% of adolescents report being cyberbullied, with a slight increase in both victimization and perpetration compared to previous years​.
  • Gender differences in violence. Boys are more likely to engage in physical fights and perpetrate both school bullying and cyberbullying.
  • Need for interventions. Multi-level approaches involving schools, families and communities are critical.

















Volume 3: Substance use

  • Substance use increases with age. 15% of adolescents smoke cigarettes, 20% use e-cigarettes and 37% reported alcohol use in the past 30 days.
  • E-cigarettes surpass smoking. E-cigarette use surpasses cigarette smoking from age 13, with 20% of 15-year-olds regularly using e-cigarettes compared to 15% smoking cigarettes.
  • Gender trends. Girls have caught up with or surpassed boys in alcohol and e-cigarette use by age 15, though cannabis use remains higher among boys.
  • Health impacts. Early initiation of substance use is associated with physical and mental health issues, including addiction.

Vol. 4: Physical activity, eating behaviours and body image

  • Low physical activity rates. Only 25% of boys and 15% of girls achieve the recommended 60 minutes of daily physical activity.
  • Unhealthy eating patterns. Less than 40% of adolescents eat fruits or vegetables daily, and breakfast consumption has declined since 2018​.
  • Rising overweight and obesity rates. 22% of adolescents are overweight or obese, with higher rates among boys and less affluent groups. This has increased since 2018 (20%).
  • Body image concerns. Nearly 30% of adolescents report feeling "too fat", with higher rates among girls (34%) than boys (24%).

Volume 5: Sexual health

  • Decline in condom use. 61% of boys and 57% of girls used condoms at last sexual intercourse, a decline from previous surveys.
  • High rates of unprotected sex. 30% of boys and 31% of girls used neither condoms nor contraceptive pills during their last sexual intercourse.
  • Gender disparities. Boys from higher-affluence families are more likely to use condoms and have higher rates of sexual initiation.
  • Comprehensive sexuality education needed. The data underscores the importance of age-appropriate, evidence-based sexuality education across countries.











Volume 6: Social media use and digital gaming

  • Continuous online contact. 36% of adolescents reported continuous online contact with friends, with a higher prevalence among girls.
  • Problematic social media use. 11% of adolescents report problematic social media use, up from 7% in 2018, with rates particularly high among girls (13%) compared to boys (9%).
  • Digital gaming trends. 34% of adolescents play digital games daily, and 12% are at risk of problematic gaming, with higher rates among boys.
  • Socioeconomic divides. Adolescents from affluent families engage more in digital behaviours, while those from lower-income families tend to use social media less actively.

Volume 7: Social contexts

  • Significant decline in family support for girls. The proportion of girls reporting high levels of family support decreased notably between 2018 and 2022, especially among 13- and 15-year-olds (10 and 9 percentage-point difference respectively), widening the gender gap.
  • Substantial increase in school pressure. There has been a steady rise in the percentage of adolescents feeling pressured by schoolwork between 2014 and 2022, with a particularly sharp increase since 2018 among 13- and 15-year-old girls.
  • Decrease in teacher and classmate support. Perceived support from teachers and classmates declined across all age and gender groups between 2018 and 2022, with the decline being more pronounced among girls.
  • Importance of combined support sources. Adolescents who felt supported by both family and peers reported significantly better mental health and well-being outcomes compared to those with support from only one source or none.
