Gender differences in knowledge about chlamydia among rural high school students in Nova Scotia, Canada
Bibliographic record
Abstract
BACKGROUND: Chlamydia is the most prevalent sexually transmissible infection (STI) in Canadian adolescents. STI account for 20% of cases of infertility in Canada and 42% of ectopic pregnancies are attributable to previous chlamydia infection. Despite the importance of this infection, little is understood about young people's knowledge of it. METHODS: A survey was conducted at a rural high school in Nova Scotia, Canada, to assess students' knowledge of chlamydia and associations of knowledge with gender and protective behaviours. Knowledge was assessed using true-false responses to 15 statements about chlamydia. Each statement was examined for differences in the percentage of correct responses by sex. Correct responses were summed, creating a knowledge score. Socioeconomic status variables and age were included in multivariate regression models to determine if they modified associations between knowledge score and protective behaviours seen in simple regression. RESULTS: Eighty-six percent of registered students (n = 538) participated in the survey. Girls responded to 10 of the 15 knowledge statements significantly more often than boys. Respondents were least knowledgeable about their rights to confidential health services for chlamydia infection. Knowledge score was associated with use of both condoms and oral contraception at last intercourse in girls (odds ratio 1.15; 95% confidence interval 1.01-1.31). No association of knowledge score was seen with having had an STI test in the previous year. CONCLUSIONS: School sexual health programs should make special efforts to meet the needs of male students, and programs and health professionals should include information about the confidential nature of sexual health services for 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.
