Key result
Each kilogram increase in birth weight significantly increased the risk of shoulder dystocia (OR 58.857), alongside fetal abdominal circumference, though other risk factors showed low sensitivity.
Why the study?
The study was designed to evaluate maternal, obstetric, and fetal risk factors, shoulder dystocia maneuvers, and perinatal outcomes of shoulder dystocia cases.
Population
66 shoulder dystocia cases and 201 controls from 36390 singleton vaginal deliveries
Comparison
Documented shoulder dystocia vs controls
Design
Descriptive retrospective cross-sectional study

Elevated birth weight may raise shoulder dystocia risk; hypothesis-generating and should not yet change practice.

Birth weight and abdominal circumference are the most significant predictors of shoulder dystocia, though its unpredictable nature remains due to the low sensitivity of other risk factors.
Köse et al. (2022) conducted a cross-sectional in Shoulder dystocia (n=267). Birth weight (per kg increase) vs. Lower birth weight was evaluated on Shoulder dystocia (OR 58.857, 95% CI 8.400-412.401, p=<0.001). Each kilogram increase in birth weight significantly increased the risk of shoulder dystocia (OR 58.857), alongside fetal abdominal circumference, though other risk factors showed low sensitivity.
