To assess the prevalence of, and factors associated with, vaginal penetration before condom application and following condom removal among young people in education in England.
A large cross sectional survey (n = 1373) was conducted in educational establishments in England and sexual event diaries were completed by a subsample of young people over a 6 month period.
Of the 375 survey respondents who reported having used a condom on the most recent occasion of vaginal sex, 6% had applied the condom after penetration and 6% had continued penetration after condom removal. Of the 74 diary respondents, 31% applied a condom late and 9% removed a condom early at least once over a 6 month period. The odds of "imperfect" condom use were found to decrease with overall consistency of condom use, confidence in correct condom use, positive reported relationship with mother, non-use of other contraception, and desire to use a condom.
Given that late application and early removal of condoms fail to maximise their effectiveness as a method of STI prevention, it is important to address "imperfect" condom use and the factors associated with such use in public health policies and programmes. It is essential that young people understand the importance of using condoms consistently and correctly, and are also equipped with the skills and knowledge to do so.
评估英格兰接受教育的年轻人在使用避孕套之前以及取下避孕套之后发生阴道插入行为的发生率及相关因素。
在英格兰的教育机构开展了一项大型横断面调查（n = 1373），部分年轻人在6个月的时间里完成了性活动日记。
在375名报告在最近一次性交中使用了避孕套的调查对象中，6%在插入后才使用避孕套，6%在取下避孕套后继续插入。在74名填写日记的对象中，31%至少有一次在6个月内延迟使用避孕套，9%至少有一次提前取下避孕套。研究发现，随着避孕套使用的总体一致性、对正确使用避孕套的信心、与母亲的积极关系报告、不使用其他避孕方法以及使用避孕套的意愿增强，“不完美”使用避孕套的几率会降低。
鉴于延迟使用和提前取下避孕套无法最大限度地发挥其作为预防性传播感染方法的有效性，在公共卫生政策和项目中解决“不完美”使用避孕套的问题以及与此类使用相关的因素非常重要。年轻人必须了解始终正确使用避孕套的重要性，同时也要具备这样做的技能和知识。
