背景：作为restat2项目的一部分，本系统综述旨在确定25个欧盟国家少女怀孕的相关因素。方法：检索策略包括电子书目数据库（1995年至2005年5月）、选定文章的书目以及要求研究小组所有国家代表提供相关报告和出版物。主要结局指标为受孕。纳入标准是对欧盟国家青少年（13-19岁）怀孕相关个人因素的定量研究。结果：在4444项研究中，有20项符合纳入标准。大多数纳入的研究发生在英国和北欧国家。众所周知，社会经济劣势、家庭结构破裂、教育水平低和抱负低等因素似乎一直与少女怀孕有关。然而，关于获得服务本身是一种保护因素的证据仍然不一致。尽管有报告称与各种冒险行为和生活方式、性健康知识、态度和行为有进一步的联系，但这些因素的独立影响也尚不清楚。结论：纳入的研究在使用的方法和定义方面差异很大。研究中的这种异质性留下了两个突出的问题。首先，我们无法综合或概括所有这些因素如何相互作用以及哪些因素最重要的关键发现。其次，不可能检查国家之间的潜在差异。确保与青少年性健康结果相关的结果具有可比性和普遍性的未来研究将有助于深入了解观察到的怀孕率的国际差异，并更好地为干预提供信息。
Background: As part of the REPROSTAT2 project, this systematic review aimed to identify factors associated with teenage pregnancy in 25 European Union countries. Methods: The search strategy included electronic bibliographic databases (1995 to May 2005), bibliographies of selected articles and requests to all country representatives of the research team for relevant reports and publications. Primary outcome measure was conception. Inclusion criteria were quantitative studies of individual-level factors associated with teenage (13-19 years) pregnancy in EU countries. Results: Of 4444 studies identified and screened, 20 met the inclusion criteria. Most of the included studies took place in UK and Nordic countries. The well-recognized factors of socioeconomic disadvantage, disrupted family structure and low educational level and aspiration appear consistently associated with teenage pregnancy. However, evidence that access to services in itself is a protective factor remains inconsistent. Although further associations with diverse risk-taking behaviours and lifestyle, sexual health knowledge, attitudes and behaviour are reported, the independent effects of these factors too remain unclear. Conclusions: Included studies varied widely in terms of methods and definitions used. This heterogeneity within the studies leaves two outstanding issues. First, we cannot synthesize or generalize key findings as to how all these factors interact with one another and which factors are the most significant. Second, it is not possible to examine potential variation between countries. Future research ensuring comparability and generalizability of results related to teenage sexual health outcomes will help gain insight into the international variation in observed pregnancy rates and better inform interventions.
