Nicotine Dependence and Regular Nicotine Use in Adult Children of Alcoholics
Bibliographic record
Abstract
In this study the relation between parental alcoholism and tobacco use and nicotine dependence in adult children is explored. Data were used from the National Comorbidity Survey (NCS), a nationwide survey of the US population aged 15 to 54. A sample of 2,728 subjects was selected who could answer all relevant questions about either their father or mother. Regular tobacco use and nicotine dependence are found to be strongly related to having an alcoholic parent. Among subjects who used tobacco regularly at some time, adult children of alcoholics (ACOAs) had a higher risk of developing nicotine dependence (attributable risk: 13.3%), and ACOAs had started regular nicotine use earlier (mean age 18.22 years in ACOAs versus 16.60 in non-ACOAs). The relation between parental alcholism and nicotine dependence in ACOAs can be related to a genetic predisposition or to environmental factors.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
