Infant well-child visits are increasingly being explored as opportunities to address parental postpartum health needs, including those related to reproductive health. To inform potential pediatric clinic-based interventions, this study assessed postpartum contraceptive needs and health services preferences. We surveyed postpartum individuals attending 2 to 6-monthwell-child visits at three Northern California pediatric clinics (2019-20). We examined unmet contraceptive needs; the acceptability of contraceptive education, counseling, and provision at well-child visits; and sociodemographic and clinical correlates. We conducted univariate and multivariable regression modeling to assess associations between sociodemographic and clinical variables, the status of contraceptive needs, and acceptability measures. Study participants (n=263) were diverse in terms of race and ethnicity (13% Asian, 9% Black, 37% Latinx, 12% Multi-racial or Other, 29% White), and socioeconomic status. Overall, 25% had unmet contraceptive needs. Unmet need was more common among participants who had delivered more recently, were multiparous, or reported ≥1 barrier to obtaining contraception; postpartum visit attendance, education, race, and ethnicity were not associated with unmet need. Most participants deemed the following acceptable in the pediatric clinic: receiving contraceptive information (85%), discussing contraception (86%), and obtaining a contraceptive method (81%). Acceptability of these services was greater among participants with unmet contraceptive needs, better self-rated health, and private insurance (all P<.05). A quarter of participants had unmet contraceptive needs beyond the early postpartum period. Most considered the pediatric clinic an acceptable place to address contraception, suggesting the pediatric clinic may be a suitable setting for interventions aiming to prevent undesired pregnancies and their sequelae.
