RESUMO
STUDY OBJECTIVE: To determine if teenage patients receiving prenatal care in an adolescent-focused clinic, emphasizing long-acting reversible contraception (LARC) using motivational interviewing techniques, had higher rates of uptake of postpartum LARC than a control group. DESIGN AND SETTING: Retrospective cohort study comparing young women who received prenatal care in an adolescent-focused setting with those enrolled in standard prenatal care. PARTICIPANTS: Adolescents between the ages of 13 and 17 years receiving prenatal care within the Maricopa Integrated Health safety-net system between 2007 and 2014. INTERVENTIONS: Motivational interviewing within the context of adolescent-focused prenatal care. MAIN OUTCOME MEASURES: Rates of uptake of LARC within 13 postpartum weeks. RESULTS: The adjusted rate of LARC for adolescent-focused prenatal care participants by 13 weeks postpartum was 38% (95% confidence interval [CI], 29%-47%) compared with 18% (95% CI, 11%-28%) for standard care participants, with an adjusted odds ratio of LARC use of 2.8 (95% CI, 1.5-5.2). Among patients who received adolescent-focused prenatal care, most (27% vs 12.7%) were using an intrauterine device as opposed to an implantable contraceptive device. CONCLUSION: Participation in an adolescent-focused antepartum setting using motivational interviewing to emphasize postpartum LARC resulted in nearly 3 times higher rates of uptake compared with standard prenatal care.
