Adolescents were more likely to be nulliparous, single, of Indigenous ethnicity or to have refugee status. They had higher rates of smoking, asthma, diabetes mellitus and thyroid disease. They were more likely to have an uncomplicated spontaneous vaginal delivery but were less likely to have an intact perineum and had higher rates of pre\u2010term delivery and low birth weight babies.
