In the analysis made it was found that 51% of the sample have sexual intercourse since early adolescents. The majority has information about contraceptive methods. Only 66% of adolescents who have sexual intercourse is protected against impregnation or infections; 38 have no protection at all. The most effective contraceptive methods for this group such as condom or diaphragm are not known or not used by them. 61% of young people who has sexual intercourse had a history of pregnancy, most of them having given birth to a child in first place, followed by uterine curettage and as a result they left school and a few began to work. The family doctor and the nurse must provide sexual education to the family due to the relation they have with their population.
