Study protocol for the optimisation feasibility testing and pilot cluster randomised trial of Positive Choices: a school-based social marketing intervention to promote sexual health prevent unintended teenage pregnancies and address health inequalities in England

摘要

BackgroundSince the introduction of the Teenage Pregnancy Strategy (TPS), England’s under-18 conception rate has fallen by 55%, but a continued focus on prevention is needed to maintain and accelerate progress. The teenage birth rate remains higher in the UK than comparable Western European countries. Previous trials indicate that school-based social marketing interventions are a promising approach to addressing teenage pregnancy and improving sexual health. Such interventions are yet to be trialled in the UK. This study aims to optimise and establish the feasibility and acceptability of one such intervention: Positive Choices.
