A study published in The European Journal of Contraception & Reproductive Health Care assessed awareness and knowledge of EC among adolescents in Berlin, Germany. The authors conducted a cross-sectional survey among ninth graders in a convenience sample of 13 Berlin schools in which they assessed perceived and actual knowledge on the effectiveness, timeframe, and availability of EC and on pregnancy risk in six scenarios. A total of 1177 students between 13 and 16 years of age participated in the study, and the authors found that 8.7% had never heard of EC, 38.6% knew of its effectiveness, but only 12.7% knew of the timeframe for EC. Of the sources of EC, only gynaecologists were widely known, and attending a school of lower academic standard and being of immigrant background was associated with lower knowledge on the majority of items. The authors conclude that generally, students were aware of the existence of EC, but many lacked the knowledge of when to take it and how to access it. See the citation below for more information:
