Very few studies have compared the prevalence of sexually transmitted infections (STIs) and risk factors particularly among men who have sex with men (MSM) with the non-MSM group.
(1) To compare the profile of STIs among MSM and non-MSM attending our STI clinic, (2) To identify the risk factors for STIs among MSM.
In this comparative cross-sectional study, we analyzed the records of all male attendees of our STI clinic from March 2015 to March 2020 for demographic details, sexual history, clinical examination and laboratory findings.
Chi-square test and logistic regression were utilized in analysis.
The number of both MSM and non-MSM attending the clinic increased over 5 years with a more sharp increase in the number of MSM, after 2017. 68.9% of MSM had their first sexual contact before attaining 20 years of age. The most common STIs were syphilis (53.75%), genital warts (30%) and herpes genitalis (20.62%). Syphilis was the most frequent STI among MSM (48/74, 64.90%) as well as non-MSM (38/86, 44.20%); though its frequency was significantly more among MSM ( < 0.01). Being unmarried (odds ratio [OR] = 3.58, 95% confidence interval [CI] = 1.85-6.93, < 0.01), having more than two sexual partners (OR = 4.49, 95% CI = 2.12-9.50, < 0.01), practising peno-oral sex (OR = 4.74, 95% CI = 2.33-9.62, < 0.01) and peno-anal sex (OR = 19, CI = 8.55-42.38, < 0.01) were significantly associated with MSM behavior.
There was an increasing trend of MSM attending the STI clinic from the year 2017. MSM persons are likely to be younger, unmarried, and have more than two sex partners. The commonest STI among MSM was syphilis.
极少有研究比较过性传播感染（STIs）的患病率及风险因素，尤其是在男男性行为者（MSM）与非男男性行为者群体之间。
（1）比较前来我们性传播感染诊所就诊的男男性行为者和非男男性行为者的性传播感染概况；（2）确定男男性行为者中性传播感染的风险因素。
在这项比较性横断面研究中，我们分析了2015年3月至2020年3月期间所有前来我们性传播感染诊所就诊的男性患者的记录，包括人口统计学细节、性史、临床检查和实验室检查结果。
分析中采用卡方检验和逻辑回归。
在5年期间，前来诊所就诊的男男性行为者和非男男性行为者的人数均有所增加，2017年后男男性行为者人数增长更为明显。68.9%的男男性行为者在20岁之前有过首次性接触。最常见的性传播感染是梅毒（53.75%）、尖锐湿疣（30%）和生殖器疱疹（20.62%）。梅毒是男男性行为者（48/74，64.90%）以及非男男性行为者（38/86，44.20%）中最常见的性传播感染；不过其在男男性行为者中的发生率显著更高（<0.01）。未婚（比值比[OR]=3.58，95%置信区间[CI]=1.85 - 6.93，<0.01）、有两个以上性伴侣（OR = 4.49，95% CI = 2.12 - 9.50，<0.01）、进行口交（OR = 4.74，95% CI = 2.33 - 9.62，<0.01）和肛交（OR = 19，CI = 8.55 - 42.38，<0.01）与男男性行为显著相关。
自2017年起，前来性传播感染诊所就诊的男男性行为者呈增加趋势。男男性行为者可能更年轻、未婚且有两个以上性伴侣。男男性行为者中最常见的性传播感染是梅毒。
