"Projet Jeune Leader," a youth-founded Malagasy organisation, conducted a retrospective, qualitative evaluation of a CSE programme in Madagascar. The…

We investigate the mechanisms by which a student's age relative to classmates (i.e., relative age) influences risky health behaviors among European adolescents. Using a two-stage least squares approach, we show that relatively young students are more prone to engage in risky behaviors. These results hold after controlling for absolute age, country…
