Teen mental health tied to more than sleep, diet, and exercise, study finds
Researchers at the University of the Sunshine Coast followed adolescents aged 12–17 for several years using data from the Longitudinal Adolescent Brain Study. They found that having more protective lifestyle and psychosocial factors—such as social connection and mindfulness—was associated with better well-being and less psychological distress later, even after accounting for prior mental health. The study suggests that supporting teen mental health may require looking beyond the traditional trio of sleep, nutrition, and physical activity.
Researchers from UniSC's Thompson Institute examined adolescents aged 12–17 over multiple years. Data came from the Longitudinal Adolescent Brain Study, which followed participants for as long as five years and collected brain scans, cognitive measures, mental health symptoms, and lifestyle information. The paper appeared in the Journal of Adolescence, with Taliah Prince and Daniel Hermens among the authors.
The team found protective factors often occurred together: teens strong in one area tended to be strong in others. Greater cumulative protection predicted later positive well-being and lower distress, even after earlier mental health was considered. Social connection and mindfulness were examined alongside sleep, nutrition, and exercise.
This story could shape how families, schools, and youth services approach adolescent mental health, perhaps prompting broader attention to social connection and mindfulness alongside sleep, diet, and exercise. Teens may benefit if support programs address multiple protective factors together rather than isolated habits. Because the findings come from one longitudinal study, wider effects on practice or policy may depend on replication and practical feasibility.
