Exclusive: Analysis of NHS data shows rates of most serious tears are nearly double those for white and black women

Asian women in England are almost twice as likely to suffer the most severe birth injuries during labour, with many healthcare professionals unaware of this greater risk, analysis has found.

Third- and fourth-degree tears, also known as obstetric anal sphincter injury (OASI), are the most severe forms of vaginal tearing during childbirth.

Up to 90% of women experience some tearing during labour, with most of these injuries healing quickly and having a relatively minor impact. A third-degree tear extends into the muscle that controls the anus and a fourth-degree tear extends further into the lining of the anus.

According to Guardian analysis of NHS figures obtained via a freedom of information request, Asian women suffered third- and fourth-degree tears at a rate of 2,831 tears per 100,000 deliveries during 2023-24. This compares with rates of 1,473 per 100,000 for white women and 1,496 per 100,000 for black women.
