To prospectively evaluate the protective value of consistent and correct use of latex condoms against the acquisition of Chlamydia trachomatis, Neisseria gonorrhoeae and Trichomonas vaginalis.
Patients (N=929) attending clinics that treat sexually transmitted infections (STIs) were prospectively followed for up to 6 months. Urine STI nucleic acid amplification testing was performed at baseline, 3 months and 6 months. Participants were instructed to respond to daily prompts from a handheld device by completing a report for each penile-vaginal sexual intercourse event. Generalised estimating equation models examined associations of consistent as well as consistent and correct condom use with STI incidence over 3-month intervals.
Consistent condom use was not significantly associated with STI incidence (Estimated OR (EOR)=0.75; 95% CI (CI) 0.43 to 1.30; p=0.31). However, individuals who used condoms both correctly and consistently were estimated to have 59% lower odds of acquiring an STI (EOR=0.41; 95% CI 0.19 to 0.90; p=.026), compared to those who did not.
The correct as well as the consistent use of condoms greatly reduces the odds of non-viral STI acquisition.
前瞻性评估坚持正确使用乳胶安全套对预防沙眼衣原体、淋病奈瑟菌和阴道毛滴虫感染的保护作用。
本研究前瞻性随访了 929 名就诊于性传播感染（STI）门诊的患者，随访时间最长达 6 个月。基线、3 个月和 6 个月时进行尿液 STI 核酸扩增检测。参与者被要求通过手持设备对每日提示做出回应，完成每次阴茎阴道性交事件的报告。广义估计方程模型分析了坚持使用以及坚持正确使用安全套与 3 个月间隔内 STI 发生率之间的关联。
坚持使用安全套与 STI 发病率无显著相关性（估计比值比[OR] = 0.75；95%置信区间[CI] 0.43 至 1.30；p=0.31）。然而，与未坚持正确使用安全套者相比，坚持正确使用安全套者感染 STI 的几率估计降低了 59%（OR=0.41；95% CI 0.19 至 0.90；p=0.026）。
正确且坚持使用安全套可大大降低非病毒性 STI 的感染风险。
