The analysis showed an association between geographic region, age, ethnic origin, educational level, economic level and adolescent pregnancy (p < 0.001). The lower levels of educational level and economic level presented a higher prevalence ratio of adolescent pregnancy, being higher even in situations of two or more pregnancies.
