Abstract

fetched live from OpenAlex

Objectives We examined the effect of exposure to Stressful Life Events (SLE) on risk of developing past-year DSM-5 Alcohol Use Disorder (pyAUD5). We evaluated if PRS moderated the relationship between SLE exposure and AUD development. Methods This is a secondary analysis of the National Epidemiologic Survey on Alcohol and Related Conditions III (NESARC III; N=36,309), and the newly available NESARC-III genomic dataset (N=22,848). Results. Subjects with high SLE exposure (N=4436) were at greater odds of developing AUD (OR: 1.8 95% CI: 1.5-2). We report statistically significant associations between PRS and pyAUD5 in matched data, before and after adjustment for potential confounders [before adjustment (OR: 1.07; 95%CI: 1.051.09), after adjustment (OR: 1.03; 95% CI: 1.0031.05)]. PRS moderated the relationship between SLE exposure and AUD development whereas PRS significantly interacted with stress exposure category and change in probability of pyAUD5 (p=0.04, SE: 211.84). Conclusions Our findings are consistent with literature indicating the role of stress in the development of substance use disorder, and preliminary in suggesting the clinical utility of PRS. We illustrate the interactive effect of PRS in moderating genetic vulnerability to pyAUD5.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
