ABSTRACT
This study examines the effect on junior high school students’ understanding and usage frequency of medicines gained from education about medicines during elementary school. This education which we provided is tailored to the developmental stage of the child. We conducted a questionnaire directed at the first year students of a junior high school in Tokyo. We compared the responses to questions regarding the understanding and correct usage frequency of medicines between groups of students who had graduated from the elementary school (Group A : students who graduated from the elementary school where we provided the education about medicines, Group B : all students except those in Group A). In order to compare these, we calculated the scores about questions regarding the understanding and correct usage frequency of medicines using principal component analysis (PCA). The PCA score for understanding of medicine by group A was higher than that of group B ; a significant difference was found (<i>P</i><0.001). Therefore, this suggests that receiving education about medicines may be a factor that enhances students’ understanding of medicines. The PCA score for correct usage frequency of medicine by group A was higher than that of group B; a significant difference was found (<i>P＝</i>0.043). Therefore, this suggests that receiving education about medicines may be a factor that increases students’ correct usage frequency of medicines.
