Description
Carolin Oetzmann and a large team sort depression by wrist data in this 2026 study. Depression looks very different from person to person, and self-reports capture only part of it, so the team turned to wearable trackers for an objective view.
Fitbit records from 623 people with repeat depression were grouped by a learning method that was given no diagnoses in advance. Three activity types emerged, from high to low, and four sleep types, including early, late, disrupted, and variable sleepers. People mostly stayed in their type over time, suggesting steady personal patterns rather than passing moods. The authors propose these types for cleaner research groups and tailored monitoring.
