The contextual determinants of sexually transmissible infections among street‐involved youth in North America
Bibliographic record
Abstract
Young people living on the urban street are at a significantly increased risk of HIV and other sexually transmitted infections (STIs). Much research examining the epidemiological basis for their heightened susceptibility has concentrated on the individual behaviours and characteristics associated with acquiring these infections. However, contextual factors, including the social, structural and environmental forces that influence sexual risk behaviour, are increasingly found to play an important role in shaping the transmission dynamics of HIV and STIs within these marginalised populations. This paper reviews research describing the individual and contextual factors that have been shown to influence street youth sexual behaviour and provides an analysis of the potential impact of such factors on HIV and STI transmission. In order to implement effective sexual health programmes for street-involved young people, innovative programmes are required that take into account the unique social and structural context of youth homelessness. Interventions to reduce the elevated prevalence and incidence of HIV and STIs among this population must explicitly target multi-level factors influencing the transmission dynamics of these diseases.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
