Abstract

Characterize how the rates of induced abortion differ by clinical and social patient characteristics.
Retrospective cohort analysis of pregnancies (2012-2023) in an integrated healthcare delivery system. We present the association of induced abortion by social and clinical factors; we calculated prevalence ratios (PR) from modified log-Poisson models, adjusted for all other covariates considered.
The likelihood of abortion was lower among individuals ≥40 years, individuals with obesity, Spanish speakers, and greater neighborhood deprivation; and higher for public insurance, Black race, and multiparous pregnancies.
There are substantial differences in the utilization of abortion services by social and clinical factors.
