The purposes were to determine contraceptive methods pregnant adolescents intend to use postpartum and to understand factors that predispose intention to use less effective birth control than long-acting reversible contraception (LARC).

<h4 id="absSec_2">Methodsh4>

Participants were 247 pregnant minority adolescents in a prenatal program. Intention was assessed by asking “Which of the following methods of preventing pregnancy do you intend to use after you deliver?” Multinomial logistic regression analysis was used to determine factors associated with intent to use nonhormonal (NH) contraception (male/female condoms, abstinence, withdrawal and no method) or short-/medium-acting hormonal (SMH) contraception (birth control pill, patch, vaginal ring, injectable medroxyprogesterone acetate) compared with LARC (implant and intrauterine device) postpartum.

Twenty-three percent intended to use LARC, 53% an SMH method, and 24% an NH method. Participants who intended to use NH or SMH contraceptive methods over LARC were significantly more likely to believe that LARC is not effective at preventing pregnancy, to report that they do not make decisions to help reach their goals and that partners are not important when making contraceptive decisions. Other important factors were having a mother who was aged >19 years at first birth and had not graduated from high school, not having experienced a prior pregnancy or talked with parents about birth control options, and the perception of having limited financial resources.

<h4 id="absSec_4">Conclusionsh4>

Distinct profiles of factors associated with intending to use NH or SMH contraceptive methods over LARC postpartum were identified and may inform future interventions to promote the use of LARC to prevent repeat pregnancy.
