Popis: Objective To investigate the association between perineal trauma at childbirth and maternal body mass index (BMI), and estimate the risk of perineal trauma among different BMI groups. Methods Data were retrospectively assessed from all vaginal deliveries in a UK tertiary maternity unit between 1999 and 2014. Associations between BMI at booking and first- and second-degree tears (minor perineal trauma), third- and fourth-degree tears (obstetric anal sphincter injuries [OASIS]), and frequency of instrumental deliveries were assessed. Multivariate logistic regression included the factors BMI (weight in kilograms divided by the square of height in meters), age, ethnicity, smoking, parity, pregnancy length, episiotomies, instrumental delivery, and birth weight. Results Data from 45 557 deliveries were used. Compared with women with a normal BMI (
