evidence: Background: In 1999, the UK Labour Government launched a 10-year Teenage Pregnancy Strategy for England to address the country's historically high rates and reduce social exclusion. The goal was to halve the under-18 conception rate. This study explores how the strategy was designed and implemented, and the features that contributed to its success. [...] Conclusions: As rates of teenage pregnancy are influenced by a web of inter-connected factors, the strategy was necessarily multi-faceted in its approach. As such, it is not possible to identify causative pathways or estimate the relative contributions of each constituent part. However, we conclude that six key features contributed to the success: creating an opportunity for action; developing an evidence based strategy; effective implementation; regularly reviewing progress; embedding the strategy in wider government programmes; and providing leadership throughout the programme. The learning remains relevant for the UK as England's teenage birth rate remains higher than in other Western European countries. It also provides important lessons for governments and policy makers in other countries seeking to reduce teenage pregnancy rates.
