Table 2. Perinatal outcomes in Vietnamese-born women, by episiotomy, New South Wales, Australia, 2001–2010

Perinatal outcome No. (%) of women who had an episiotomy (n = 3646) No. (%) of women who did not have an episiotomy (n = 8562) Risk of adverse perinatal outcome
cOR (95% CI) aOR (95% CI)a
Postpartum haemorrhage 387 (10.6) 635 (7.4) 1.48 (1.30–1.69) 1.26 (1.08–1.46)
Postnatal hospitalization for > 4 days 822 (22.6) 908 (10.6) 2.45 (2.21–2.72) 1.14 (1.00–1.29)
Third- or fourth-degree perineal tear
  Primiparae 146 (6.1) 233 (9.0) 0.66 (0.53–0.82) 0.47 (0.37–0.60)
  Multiparae 40 (3.2) 77 (1.3) 2.52 (1.71–3.70) 2.00 (1.31–3.06)

aOR, adjusted odds ratio; CI, confidence interval; cOR, crude odds ratio.

a The following factors were taken into account for the calculation of the aOR: maternal age, parity (for postpartum haemorrhage and postnatal hospitalization), private or public care, diabetes, hypertension, induction of labour, epidural analgesia, mode of delivery and birth weight.
