International travel facilitates global spread of sexually transmitted infections (STI). Travellers could contribute to onward transmission of pathogens rarely encountered at home and export new strains to the destination. The aim was to systematically examine evidence regarding determinants of travel-related sexual risk-taking and identify knowledge gaps and areas for targeted interventions.
Articles published in peer-reviewed journals from 2000 to 2017 were screened in 6 databases and assessed for relevance against criteria. Data was extracted for factors associated with travel-related STI or proxies. Meta-analyses estimated pooled prevalence of casual sex and non-condom use. Adjusted odds ratios of predictors were pooled to generate a combined estimate.
Forty-nine articles qualified for inclusion. A heterogeneity test indicated variation across studies. The pooled prevalence of casual travel sex was 35% and prevalence of non-condom use 17%. Expectations of casual sex strongly predicted sex with a new partner when travelling abroad. Planning to have sex indicated condom use.
The studies largely represented sub-groups of risk-taking populations from a European context, indicating substantial knowledge gaps. Studies investigating migrants travelling to visit friends and relatives, older travellers, and female travelers are needed. Post-travel harm reduction activities may serve as a focus for future interventions.
国际旅行促进了性传播感染（STI）的全球传播。旅行者可能会将在家中很少遇到的病原体传播出去，并将新的菌株输出到目的地。本研究旨在系统地研究与旅行相关的性风险行为的决定因素的证据，并确定知识空白和有针对性干预的领域。
从 2000 年至 2017 年，在 6 个数据库中筛选了同行评审期刊上发表的文章，并根据标准评估了相关性。提取了与旅行相关的性传播感染或替代指标相关的因素的数据。对偶然性行为和非避孕套使用的调整后优势比进行荟萃分析，以生成综合估计值。
有 49 篇文章符合纳入标准。异质性检验表明研究之间存在差异。偶然旅行性行为的总体流行率为 35%，非避孕套使用的流行率为 17%。在国外旅行时，对随意性行为的期望强烈预测了与新伴侣的性行为。计划发生性行为表明会使用避孕套。
这些研究主要代表了来自欧洲背景的风险人群的亚组，表明存在大量知识空白。需要研究移民前往探亲访友、老年旅行者和女性旅行者。旅行后的减少伤害活动可能成为未来干预的重点。
