摘要

Background

Psychosomatic symptoms are a significant concern in adolescence, which can substantially impact their psychosocial development. We aimed to investigate the association between various health behaviours- including dietary behaviours, physical activity, smoking, and alcohol consumption- and psychosomatic symptoms among adolescents in 45 countries.

Methods

We utilised data from 239,439 adolescents aged 10–16 years across 45 countries from the 2017–2018 Health Behaviour in School-Aged Children survey. Psychosomatic symptoms were assessed through an eight-item symptom checklist over the past six months. A mixed-effect linear regression model was employed to examine the association.

Results

The mean (SD) psychosomatic symptom score was 8.69 (6.77), with higher scores among females compared to males (p < 0.001). Unhealthy dietary behaviours, including daily soft drinks (β: 0.43, 95% CI: 0.33, 0.52) and sweet consumption (β: 0.94, 95% CI: 0.86, 1.02), and skipping breakfast (β: 2.00, 95% CI: 1.93, 2.06) were positively associated with psychosomatic symptoms. Additionally, smoking (β: 2.39, 95% CI: 2.25, 2.52) and alcohol intake (β: 1.64, 95% CI: 1.55, 1.73) in the past 30 days were also linked to higher psychosomatic symptom scores. Conversely, healthy behaviours, including daily fruit (β: -0.34, 95% CI: -0.41, -0.26) and vegetable intake (β: -0.09, 95% CI: -0.16, -0.02), and sufficient physical activity (β: -0.41, 95% CI: -0.49, -0.32) were associated with lower psychosomatic symptom scores.

Conclusion

The present study highlighted a significant association between adolescent health behaviours and psychosomatic symptoms. Public health interventions should prioritise promoting healthier lifestyles to mitigate psychosomatic distress and enhance overall well-being among adolescents globally.
