Linking extremely low birth weight and internalizing behaviors in adult survivors: Influences of neuroendocrine dysregulation
Bibliographic record
Abstract
Young adult survivors of extremely low birth weight (ELBW; <1000 g) are known to be at elevated risk for internalizing problems, though little is known about the mechanisms that may lead to higher levels of psychopathology in this vulnerable group. We examined the moderating influence of neuroendocrine functioning on the link between being born at ELBW and internalizing behaviors at age 30-35. Salivary cortisol was collected 20 min after completion of a social stress task in 83 ELBW adult survivors and 89 normal birth weight (NBW; >2500 g) controls. Using a median split, participants were separated into two groups (high or low afternoon cortisol levels). ELBW survivors with "high" afternoon cortisol levels self-reported significantly higher levels of internalizing behaviors compared to those with "low" afternoon cortisol levels. This association between afternoon cortisol and internalizing symptoms did not exist among NBW controls. These results are suggestive of a differential susceptibility for internalizing behaviors among ELBW survivors, depending on their ability to regulate neuroendocrine responses.

How this classification was reachedexpand
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.
