RESUMO
The purpose of this study is to describe and compare the prevalence of mental health problems in Aymara and non-Aymara children and adolescent. The study sample comprised 1839 students from 8 to 19 years, from educational institutions of Northern Chile. Forty-nine percent of students identified with the Aymara ethnic group. The Child and Adolescent Evaluation System was used to evaluate internal and external problems. In Elementary school, Aymara students showed significantly lower scores in externalized problems and in high school, there were significantly lower scores in interiorized, exteriorized and other problems than Non-Aymara students. It seems that the legacy of the Aymara culture has favored the development of protective factors in relation to the mental health of these students. In a context of growing recognition and appreciation of this culture, greater involvement with Aymara culture could promote better mental health of school children.
