This umbrella review synthesized evidence from 49 systematic reviews involving 1.9 million participants under 19 years to evaluate the impact of diet, sleep, and physical activity on depression in children and adolescents. It found that greater sleep disruption and unhealthier diets correlated with increased depression symptoms (g = 0.55 and 0.14), while longer sleep duration, healthier diets, and increased physical activity were linked to fewer symptoms (g = -0.40, -0.16, and -0.16, respectively).
Key findings
- Greater sleep disruption was associated with increased depression symptoms (g = 0.55).
- Healthier diets correlated with fewer depression symptoms (g = -0.16).
- Increased physical activity was linked to reduced depression symptoms (g = -0.16).
- Intervention reviews showed a strong association between increased physical activity and fewer depression symptoms (g = -0.54).
Why it matters
Understanding the relationship between health behaviors and depression in adolescents is crucial for developing effective interventions. This review highlights the importance of promoting better sleep and physical activity as potential strategies to alleviate depressive symptoms in this population.
