One in five pregnancies in the UK ends in abortion. The great majority of those pregnancies are unintended, resulting from incorrect, inconsistent or non-use of contraception, rather than contraception failure. We undertook a synthesis of qualitative research with women who have unintended pregnancies as a new approach to understanding contraceptive behaviour. A literature search was carried out using four databases. Identified studies were screened against pre-set inclusion criteria. Included studies were quality assessed. Analysis followed a meta-ethnographic approach. A total of 236 studies were identified, of which nine were included. Six categories involved in contraceptive behaviour were identified - access, method factors, knowledge, societal influence, personal beliefs and motivations and relationship factors. A model of contraceptive behaviour was developed. Contraceptive behaviour is a complex, multifactorial process. Interventions targeting one aspect are unlikely to make a difference; however identifying and affecting the important factors within a population may improve contraception adherence.
在英国，五分之一的怀孕以堕胎告终。这些怀孕中的绝大多数是意外怀孕，是由于避孕措施使用不当、不一致或未使用，而非避孕失败所致。我们对意外怀孕的女性进行了定性研究综合分析，作为理解避孕行为的一种新方法。使用四个数据库进行了文献检索。根据预先设定的纳入标准对检索到的研究进行筛选。对纳入的研究进行质量评估。分析采用元民族志方法。共识别出236项研究，其中9项被纳入。确定了避孕行为涉及的六个类别——获取途径、方法因素、知识、社会影响、个人信念和动机以及关系因素。构建了一个避孕行为模型。避孕行为是一个复杂的、多因素的过程。针对一个方面的干预不太可能产生效果；然而，识别并影响人群中的重要因素可能会提高避孕措施的依从性。
