“…In a study by Robinson et al, shoulder dystocia was found to be strongly related to foetal macrosomia; as in other studies, obesity was not an independent risk factor for shoulder dystocia [110,111]. It can be concluded that for obese women, the same predictors for shoulder dystocia apply as for nonobese women [111]. The risk of shoulder dystocia was 33% in vaginal deliveries of infants with birth weights >4,500 g and only 2% in infants with birth weights <4,500 g. These figures must be interpreted cautiously because they are based on a relatively small sample size [112].…”

“…The positive predictive value of obesity for predicting fatal shoulder dystocia is very low, 13/42,000 for BMI >35 kg/m 2 , and 4/10,000 for BMI >40 kg/m 2 [109]. In a study by Robinson et al, shoulder dystocia was found to be strongly related to foetal macrosomia; as in other studies, obesity was not an independent risk factor for shoulder dystocia [110,111]. It can be concluded that for obese women, the same predictors for shoulder dystocia apply as for nonobese women [111].…”

Obesity is presently the most prevalent health threat in the western world, and its influence on general health is rapidly increasing. Obesity has also developed as a major and frequent risk factor for pregnancy complications. Complications often encountered in obese pregnant women are hypertensive disorders, gestational diabetes mellitus, caesarean section, and postpartum and postoperative infections. The incidence of pulmonary embolism and primary postpartum haemorrhage is most likely also increased. Anaesthetic complications are more frequent. Neonatal consequences of obesity include an increased rate of congenital anomalies, stillbirth, and macrosomia. This article focuses on practical implications of obesity in pregnancy and childbirth for the caregiver.

“…Adipöse Frauen gebären jedoch öfter makrosome Kinder oder leiden an Diabetes. Beides sind Risikofaktoren für die Schulterdystokie, bei deren Berücksichtigung keine unabhängige Assoziation zwischen Adipositas und erschwerter Entwicklung der Schulter festzustellen ist [22].…”

Adipositas wird je nach Schwere in die Grade I, II und III [BMI > 40 kg/m 2 (Body-Mass-Index)] unterteilt. In Deutschland weisen 16 Mio. Menschen einen BMI > 30 kg/m 2 auf, jeder 3. Erwachsene ist stark über-gewichtig. Adipositas bei jungen Frauen ist ein gesellschaftliches Phä-nomen, das zunehmend auch zu Herausforderungen in der Geburtsmedizin führt. Im Jahr 2014 hatten 21,3 % der Schwangeren in Deutschland einen BMI von 25-29 kg/m 2 und galten damit als übergewichtig. Bei 13,6 % betrug der BMI > 30 kg/m 2 , diese Frauen erfüllten somit das Kriterium für Adipositas. Die Zahlen für 2013 waren vergleichbar.

“…Others [62] found that 5% of extremely obese (over 250 pounds) women were found to have experienced shoulder dystocia. For obese non-diabetic women carrying fetuses whose weights were estimated to be within normal limits, there was no increased risk of shoulder dystocia [63]. The issue is further complicated by the decreased ability to accurately estimate fetal weight at the upper extremes of the growth curve, with errors exceeding 10% of the birth weight, in particular on the basis of suboptimal visualization [64,35].…”

The obesity epidemic is a problem of global importance with a profound impact on maternal-fetal health. Maternal overweight and obesity causes pregnancy complications such as gestational diabetes, hypertension and preeclampsia and affects fetal growth. Maternal obesity offers an altered genetic, hormonal and biochemical environment for the developing fetus/embryo and influences fetal growth and organ development. Offspring of obese mothers are subject to an increased risk of fetal demise, congenital anomalies and disrupted growth patterns, causing an increase in perinatal mortality. The impact of maternal obesity extends beyond intrauterine and neonatal life to childhood, adolescence and adulthood.

Is maternal obesity a predictor of shoulder dystocia?

Abstract: The strongest predictors of shoulder dystocia are related to fetal macrosomia. For obese nondiabetic women carrying fetuses whose weights are estimated to be within normal limits, there is no increased risk of shoulder dystocia.
