Sex related knowledge,attitudes and behaviors among middle school students in Shanghai city
Bibliographic record
Abstract
Objective To understand sex related knowledge,attitudes and behaviors among middle school students in Shanghai.Methods A total of 3 069 grade one junior high or senior high middle school students from 11 middle schools in one district of Shanghai were interviewed by using anonymous self-administered questionnaire.Results The knowledge scores of middle and high school students were rather low with the mean score being 33.85 and 55.08 respectively,while their attitudes toward sexual issues were relatively open.About four fifth of the high school students and more than half of the middle school students approved or accepted premarital sexual behavior.A quarter of the high school students and 6 percent of the middle school students ever dated or had a hug with opposite sex.Conclusion With the increase of age,middle school students were more likely to hold an open attitude to sex and were more likely to have sex related behaviors.However,they had poor knowledge on reprodctive health.It was necessary to strengthen family and school sex education in Shanghai.

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.
