Abstract

There is an ethnic Aymara group with well defined sociocultural characteristics in the highlands of the 1° region of Chile. They have tendency towards the endogamy, which they have sustained through time and in the last years they have had moved towards the urban sector. Due to emigration it is important to know the prevalence the Trichomona vaginalis on this ethnic group, resident in the urban zone of Arica. The study was performed in 95 Aymara women infertile age which had emigrated to the urban zone. In every woman a gynaecological exam was performed and a sample of vaginal secretions was taken for the determination of T. vaginalis. The results from these studies showed that the prevalence the T. vaginalis was of 10.5%. In relation to the infection grade by age, the most common percentage showed between 20 to 29 years old. The 11.1% of women with T. vaginalis begin its sexual activity between 16 and 25 years of age. Sexual promiscuous is the 40% and from them the 15.8% was in infected. Beetween the woman which remain social cultured attached to their natural habitat only 4.9% was infected. We can conclude that the Aymara woman migrating and establishing in the urban sector, without keeping bonds with their origin place, received the impact the urban medium provoking the increase of the T. vaginalis.
