Sexual behaviour of backpackers who visit Koh Tao and Koh Phangan, Thailand: a cross-sectional study
Bibliographic record
Abstract
OBJECTIVES: To measure the proportion of backpackers engaging in unprotected sex while travelling in Thailand and to identify predictors of unsafe sexual behaviour. METHODS: A cross-sectional study using an anonymous questionnaire was performed. English-speaking backpackers, excluding US and Thai citizens, were recruited while travelling through the piers of Koh Tao and Koh Phangan between 25 January and 13 March 2013. RESULTS: 61.5% (1238/2013) respondents were travelling without a long-term sexual partner, of whom 39.1% (29.4% females; 51.9% males) reported intercourse with a new partner. 36.8% of these reported inconsistent/no condom use. Inconsistent condom use was independently associated with age <25 years, UK (vs Canadian) nationality and not bringing condoms from home. Backpackers who brought condoms from home were more likely to have sex with a new partner. Male gender and longer trip length increased the likelihood of new partner acquisition and overall risk of unsafe sex but were not associated with inconsistent condom use. New partners were most commonly backpackers from other countries. Men were more likely than women to have sex with a local person. CONCLUSIONS: Backpackers visiting Thailand frequently report unsafe sex. Partner demographics demonstrate a mechanism of international sexually transmitted infection (STI) transfer. In an era of growing antibiotic resistance and continuing HIV transmission, targeting unsafe sex in backpackers has the potential to reduce STI incidence internationally. These data highlight the need for innovative public health intervention. To focus such measures, future research may elucidate why certain groups are at higher risk.

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.
