Abstrakt:	Objective We estimated the association between diabetes and shoulder dystocia by infant birth weight subgroups (<4,000, 4,000–4,500, and >4,500 g) in an era of prophylactic cesarean delivery for suspected macrosomia. Study Design A secondary analysis from the National Institute of Child Health and Human Development U.S. Consortium for Safe Labor of deliveries at ≥24 weeks with a nonanomalous, singleton fetus with vertex presentation undergoing a trial of labor. The exposure was either pregestational or gestational diabetes compared with no diabetes. The primary outcome was shoulder dystocia and secondarily, birth trauma with a shoulder dystocia. We calculated adjusted risk ratios (aRRs) with modified Poison's regression between diabetes and shoulder dystocia and the number needed to treat (NNT) to prevent a shoulder dystocia with cesarean delivery. Results Among 167,589 assessed deliveries (6% with diabetes), pregnant individuals with diabetes had a higher risk of shoulder dystocia at birth weight <4,000 g (aRR: 1.95; 95% confidence interval [CI]: 1.66–2.31) and 4,000 to 4,500 g (aRR: 1.57; 95% CI: 1.24–1.99), albeit not significantly at birth weight >4,500 g (aRR: 1.26; 95% CI: 0.87–1.82) versus those without diabetes. The risk of birth trauma with shoulder dystocia was higher with diabetes (aRR: 2.29; 95% CI: 1.54–3.45). The NNT to prevent a shoulder dystocia with diabetes was 11 and 6 at ≥4,000 and >4,500 g, versus without diabetes, 17 and 8 at ≥4,000 and >4,500 g, respectively. Conclusion Diabetes increased the risk of shoulder dystocia, even at lower birth weight thresholds than at which cesarean delivery is currently offered. Guidelines providing the option of cesarean delivery for suspected macrosomia may have decreased the risk of shoulder dystocia at higher birth weights. Key Points >Diabetes increased the risk of shoulder dystocia, even at lower birth weight thresholds than at which cesarean delivery is currently offered. Cesarean delivery for suspected macrosomia may have decreased the risk of shoulder dystocia at higher birth weights. These findings can inform delivery planning for providers and pregnant individuals with diabetes. [ABSTRACT FROM AUTHOR]
