Evidence is mixed as to whether meeting sexual partners online ('internet-partners') is associated with risky sexual behaviour and/or sexually transmitted infection transmission. Accordingly, we sought to estimate the prevalence of reporting various online romantic and sexual activities among Norwegian adolescents, including internet-partners, and the reason for meeting them and to examine differences in sexual behaviour, partnership characteristics and chlamydia infection prevalence among those reporting internet-partners versus those reporting only offline partners.
Population-based cross-sectional survey among sexually experienced girls and boys, 15-20 years, using electronic questionnaires and collecting urine samples for Chlamydia trachomatis PCR testing (79% provided both, n=1023). We used logistic regression to examine associations, adjusting for potentially confounding variables.
Overall, 30% of both genders reported internet-partners (ever). Boys (but not girls) with internet-partners had higher chlamydia prevalence than those reporting meeting sexual partners only offline (8.1%, 95% CI 4.3% to 13.7% vs 1.6%, 0.5% to 3.7%). Two-thirds of girls and 37% of boys reported meeting their most recent internet-partner to start a romantic relationship, while the remainder did so with the specific intention of having sex. Among both genders, reporting sexual (vs romantic) reasons for meeting their most recent internet-partners was associated with reporting several risky sexual behaviours, including multiple recent sex partners (adjusted OR girls: 3.27, boys: 2.48) and three-fold higher chlamydia prevalence.
This population-based study suggests that internet-partners are common among adolescents in Norway, and the reason for meeting them was more strongly associated with additionally reporting sexual risk behaviours and prevalent chlamydia infection than the internet itself as a meeting venue.
关于通过网络结识性伴侣（“网络伴侣”）是否与危险性行为和/或性传播感染传播相关，证据并不一致。因此，我们试图估算挪威青少年中报告各种网络浪漫及性活动（包括网络伴侣）的比例、结识他们的原因，并比较报告有网络伴侣的青少年与仅报告有线下伴侣的青少年在性行为、伴侣特征及衣原体感染率方面的差异。
对15至20岁有性经历的青少年男女进行基于人群的横断面调查，采用电子问卷并收集尿液样本进行沙眼衣原体PCR检测（79%的人同时提供了问卷和样本，n = 1023）。我们使用逻辑回归分析关联性，并对潜在的混杂变量进行调整。
总体而言，30%的青少年（无论男女）报告有过网络伴侣。有网络伴侣的男孩（而非女孩）的衣原体感染率高于仅报告有线下性伴侣的男孩（8.1%，95%可信区间4.3%至13.7%，对比1.6%，0.5%至3.7%）。三分之二的女孩和37%的男孩报告称结识最近的网络伴侣是为了开始浪漫关系，而其余人结识则是出于特定的性行为目的。在男女两性中，报告因性（而非浪漫）原因结识最近的网络伴侣与报告多种危险性行为相关，包括近期有多个性伴侣（调整后的比值比，女孩：3.27，男孩：2.48）以及衣原体感染率高三倍。
这项基于人群的研究表明，网络伴侣在挪威青少年中很常见，结识网络伴侣的原因与额外报告的性风险行为及衣原体感染流行率的关联，比网络本身作为结识场所的关联更强。
