Osteocalcin: A novel biomarker of adolescent psychopathology
Bibliographic record
Abstract
Osteocalcin is a bone-derived hormone implicated in the acute stress response and recently linked to adult depression. Yet it is unclear whether osteocalcin is a biomarker of other forms of psychopathology and whether osteocalcin-psychopathology associations emerge during developmentally sensitive periods earlier in life. Thus, in the current pilot study we examined salivary osteocalcin and psychiatric symptoms and disorders among 48 early adolescents during a period of stress. A logistic regression indicated lower osteocalcin was associated with meeting criteria for a psychiatric disorder, OR = 0.43, 95 % CI [.002,.924], and showed moderate-to-large cross-sectional associations with a range of elevated psychopathology symptoms, B s ≥ |-3.44|, p s ≤.034. Multilevel linear growth models indicated that low osteocalcin prospectively predicted an even greater range of psychopathology symptoms at one-year follow-up as well as increases in some symptoms over time, B s ≥ |-1.83|, p s ≤.021. Findings introduce osteocalcin as a biomarker of diverse forms of psychopathology in youth. Osteocalcin is a potential transdiagnostic mechanism through which dysregulated responses to stress could cause or exacerbate various types of psychopathology, highlighting a promising target for clinical assessment and early intervention. • Osteocalcin is a bone-derived hormone implicated in the acute stress response. • We assessed the cross-sectional and prospective association between osteocalcin and psychopathology in youth. • Lower osteocalcin was associated with psychiatric disorders and with higher psychopathology symptoms over time. • Findings introduce osteocalcin as a biomarker of psychopathology in youth.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
