[Articles] Disparities in primary Cesarean birth by sexual orientation: a population-based analysis across three longitudinal cohorts

SM people have increased risks for primary Cesarean birth, but these vary across sexual orientation subgroups. We found increased risks for a rarely studied subgroup of sexual minority people, those who identify as heterosexual but have prior same-sex experience. These disparities are most pronounced when labor is induced. All participants were assumed to be women based on surveys querying sex and birth histories, but we were limited in generalizability due to not knowing their gender identities.
