BACKGROUND
Meeting sex partners online is associated with increased risk of acquiring sexually transmitted infections. We examined whether different venues where men who have sex with men (MSM) meet sex partners was associated with prevalent (CT) and (NG) infection, and whether prevalence increased during (vs before) the COVID-19 pandemic.
METHODS
We conducted a cross-sectional analysis of data from San Diego's 'Good To Go' sexual health clinic from two enrolment periods: (1) March-September 2019 (pre-COVID-19) and (2) March-September 2021 (during COVID-19). Participants completed self-administered intake assessments. This analysis included males aged ≥18 years self-reporting sex with males within 3 months before enrolment. Participants were categorised as (1) meeting new sex partners in-person only (eg, bars, clubs), (2) meeting new sex partners online (eg, applications, websites) or (3) having sex only with existing partners. We used multivariable logistic regression, adjusting for year, age, race, ethnicity, number of sex partners, pre-exposure prophylaxis use and drug use to examine whether venue or enrolment period were associated with CT/NG infection (either vs none).
RESULTS
Among 2546 participants, mean age was 35.5 (range: 18-79) years, 27.9% were non-white and 37.0% were Hispanic. Overall, CT/NG prevalence was 14.8% and was higher during COVID-19 vs pre-COVID-19 (17.0% vs 13.3%). Participants met sex partners online (56.9%), in-person (16.9%) or only had existing partners (26.2%) in the past 3 months. Compared with having only existing sex partners, meeting partners online was associated with higher CT/NG prevalence (adjusted OR (aOR) 2.32; 95% CI 1.51 to 3.65), while meeting partners in-person was not associated with CT/NG prevalence (aOR 1.59; 95% CI 0.87 to 2.89). Enrolment during COVID-19 was associated with higher CT/NG prevalence compared with pre-COVID-19 (aOR 1.42; 95% CI 1.13 to 1.79).
CONCLUSIONS
CT/NG prevalence appeared to increase among MSM during COVID-19, and meeting sex partners online was associated with higher prevalence.
背景
与性伴侣在线会面会增加感染性传播感染的风险。我们研究了男男性行为者（MSM）与性伴侣会面的不同场所是否与现患（CT）和（NG）感染有关，以及 COVID-19 大流行期间感染率是否增加。
方法
我们对圣地亚哥“随时准备好”性健康诊所的数据进行了横断面分析，该诊所分为两个入组期：（1）2019 年 3 月至 9 月（COVID-19 之前）和（2）2021 年 3 月至 9 月（COVID-19 期间）。参与者完成了自我管理的入组评估。本分析包括年龄≥18 岁的男性，自我报告在入组前 3 个月内与男性发生过性行为。参与者分为 1）仅与新性伴侣面对面（例如，酒吧、俱乐部）、2）在线结识新性伴侣（例如，应用程序、网站）或 3）仅与现有伴侣发生性关系。我们使用多变量逻辑回归，调整年份、年龄、种族、民族、性伴侣数量、暴露前预防使用和药物使用情况，以检查场所或入组期是否与 CT/NG 感染（与无感染相比）相关。
结果
在 2546 名参与者中，平均年龄为 35.5 岁（范围：18-79 岁），27.9%是非白人，37.0%是西班牙裔。总体而言，CT/NG 的患病率为 14.8%，COVID-19 期间高于 COVID-19 之前（17.0%比 13.3%）。参与者在过去 3 个月内通过在线（56.9%）、面对面（16.9%）或仅与现有伴侣（26.2%）结识性伴侣。与仅与现有性伴侣发生性关系相比，在线结识性伴侣与更高的 CT/NG 患病率相关（调整后的比值比（aOR）2.32；95%CI 1.51 至 3.65），而面对面结识性伴侣与 CT/NG 患病率无关（aOR 1.59；95%CI 0.87 至 2.89）。与 COVID-19 前相比，COVID-19 期间入组与更高的 CT/NG 患病率相关（aOR 1.42；95%CI 1.13 至 1.79）。
结论
在 COVID-19 期间，男男性行为者中的 CT/NG 患病率似乎有所增加，而与性伴侣在线会面与更高的患病率相关。
