This study shows how the ages of menarche, entry to union with a partner, first pregnancy, and first delivery among Embera Chamibida women come later when compared to Embera Eyabida and Zenu women; this pattern of reproductive behavior is classified in other studies as divergent with respect to the situation of the rest of the indigenous women from Antioquia (6,7,15) In these studies as in the current one, the differential reproductive behavior of the Chamibida women is related to the continued interethnic contact that has supposed that this subgroup adopts practices of the Western culture, which often go against the Embera cultural guidelines that promote population growth as an input for ethnic survival.
