The distribution of contraceptive methods used was similar among the three age groups, but the absence of contraception was most frequent in the adolescent group. The adolescents we assessed, being married and having delivered at least once, are a highly selected group and not representative of adolescents in general. Nevertheless, their contraceptive choices did not differ from those of older women. The incidence of TOPs among them was quite high. Minimization of the frequent neglect of application of contraceptive measures by adolescents requires improvement of family planning services for this age group.
