- Digital biomarkers from wrist-worn wearables are being explored as proxy markers for mental health, specifically anxiety.
- A systematic review and meta-analysis examined the association between these biomarkers and anxiety, including generalized anxiety disorder and anxiety symptoms.
- 44 studies from 42 articles were eligible, with 36 using inferential statistical approaches and 8 using machine learning approaches.
- Meta-analyses found no significant associations between sleep metrics (efficiency, wake after sleep onset, total sleep time, sleep onset latency) and anxiety.
- Qualitative syntheses suggested lower physical activity levels and higher heart rate were associated with greater anxiety symptoms.
- Machine learning studies showed varied performance, with predictive accuracy improving when wearable data was combined with other data sources.
- Digital biomarkers may be more effective when integrated with other data sources rather than used as standalone tools.
