Participants
The present trial enrolled a total of 584 female adolescents (292 in each group) who are 15–19 years of age, attending grades 9–12 at the four schools (clusters) located in Central Gondar Zone, Northwest Ethiopia. Only female adolescents who were willing to participate were included in the study. Those participants who were unable to communicate and had a plan to leave the study area or school before the completion of the study were excluded from the trial. Concerning clusters, only schools that are located in areas where pulses production is common have been included. On the other hand, whenever schools are considered to be close to each other, the one situated between schools was excluded and considered as a buffer zone to minimize information contamination.
