OBJECTIVE
To explore knowledge and use of female condoms in China, and to compare four modes of failure between the Phoenurse female condom (PFC) and the second-generation Femidom female condom (FC2).
METHODS
In a randomized, crossover trial, sexually active women aged 20-49years who attended a family planning service in Qingdao, China, were recruited between April and October, 2013. A computer-generated randomized sequence was used to assign participants (1:1) to group A (used 10 PFCs followed by 10 FC2s) or group B (used 10 FC2s followed by 10 PFCs). Study investigators and participants were masked to allocation. Participants completed questionnaires at baseline and after using the two types of FCs. They also kept coital logs.
RESULTS
At baseline, 30 (10.3%) of 290 participants understood female condoms, but only 1 (0.3%) had ever used one. Total failure rates were 3.6% (420/11 578) and 2.3% (265/11 594) for PFC and FC2, respectively (P<0.001). Slippage was the most common form of failure, affecting 6.9% of PFC uses and 5.0% of FC2 uses. Breakage, misdirection, and slippage were significantly more common with the PFC than with the FC2 (P≤0.002).
CONCLUSION
Understanding of female condoms is poor in China. Failure is more common with the PFC than with the FC2.
目的
探讨中国女性对女用避孕套的了解及使用情况，并比较菲护士女用避孕套（PFC）与第二代女用避孕套（FC2）的四种失败模式。
方法
在一项随机交叉试验中，于2013年4月至10月招募了在中国青岛参加计划生育服务的20 - 49岁性活跃女性。采用计算机生成的随机序列将参与者按1:1分配至A组（先使用10个PFC，再使用10个FC2）或B组（先使用10个FC2，再使用10个PFC）。研究调查人员和参与者对分组情况不知情。参与者在基线时以及使用两种女用避孕套后完成问卷调查。他们还记录了性交日志。
结果
基线时，290名参与者中有30名（10.3%）了解女用避孕套，但只有1名（0.3%）曾使用过。PFC和FC2的总失败率分别为3.6%（420/11578）和2.3%（265/11594）（P<0.001）。滑脱是最常见的失败形式，影响了6.9%的PFC使用和5.0%的FC2使用。PFC的破损、误置和滑脱明显比FC2更常见（P≤0.002）。
结论
中国女性对女用避孕套的了解较差。PFC的失败情况比FC2更常见。
