Table 2

Multivariate logistic regression for predicting risk of laceration.

Variable	aOR (95% CI)	value
Obesity (BMI ≥ 30 kg/m^2)	0.75 (0.58–0.98)	0.037
Asian race	1.65 (1.16–2.34)	0.002
African American race	0.67 (0.45–0.99)	0.001
Operative VD	1.56 (1.20–2.04)	0.001
Nulliparity	3.93 (2.98–5.19)	<0.001
Birthweight < 4 kg	0.46 (0.29–0.72)	0.0007
No prolonged second stage	0.42 (0.27–0.66)	0.0002
