RESUMO
Pregnancy in adolescence is a public health problem, and relapse rates make it even more serious. Out of 1,1 million parturient adolescents, 25% have a child already. We aimed to analyze the social economic cultural obstetric factors of relapse into pregnancy in adolescence in Teresina, PI, Brazil through interelational retrospective study. The sample contains 464 young who finished a gestation during the first four months in 2006. Out of those, 47.6% were in consensual union; 69.6% out of school; 86.9% with inappropriate schooling for the age; 72.2% with unpaid job. This profile evidences the lack of public policies that consider the adolescent. The elaboration and development of those policies should include family, school and the community in order to decrease pregnancy and sexually-transmited diseases rates.
