Substance use and sexual risk behaviors among Mississippi public high school students.
Bibliographic record
Abstract
This study describes the patterns of substance use and sexual risk behaviors and examines the relationships among a representative sample of Mississippi public high school students. Data were obtained from the 2009 Mississippi Youth Risk Behavior Survey. Multiple logistic regression analyses were performed. We found 61% of the participants ever had sexual intercourse and 13.4% engaged in early sexual initiation (< or = 12 years). Nearly a quarter had four or more lifetime sexual partners. One-third did not use a condom during their last sexual intercourse. Two-thirds drank alcohol. Over one-third used marijuana. Older age, being a black, drinking alcohol, or using marijuana or other drugs were associated with early sexual initiation and having multiple sexual partners. Heavy smoking was associated with early sexual initiation. Using marijuana or other drugs was associated with unprotected sex. Findings highlight the extensive substance use and engagement of sexual risk behaviors among Mississippi adolescents. Interventions that address both substance use and sexual risk behaviors may have a great impact in preventing teen pregnancy and HIV/STD transmission and curtailing substance abuse problems among Mississippi adolescents.

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.
