BACKGROUND
A growing number of studies have found that breech presentation is related to preexisting diseases and may affect future fetal development. This study aimed to compare the differences between breech presentation and cephalic presentation and explore the underlying mechanisms of adverse outcomes caused by fetal station itself.
METHODS
‘PubMed’, ‘Embase’ and ‘Cochrane Library’ were searched from inception to October 21, 2022. Comparative studies containing ‘prelabor CS’ or ‘elective CS’ of cephalic and breech presentation were included. A total of 585 studies were included, and 5 studies were eligible for final research. Review Manager 5.4.1 was used for data synthesis.
RESULTS
The mortality of breech group is not different from that of cephalic group (RR 0.69, 95% CI 0.09–5.13, = 0.71). No differences in infant (< 1 year) and neonatal (0–27 days) mortality were found between the breech and cephalic presentations (RR 1.56, 95% CI 0.86–2.82, = 0.14). However, breech group was found to have lower birth weight ( < 0.002), umbilical coiling index( < 0.0001), and bone SOS ( = 0.03 )than cephalic group.
CONCLUSIONS
The breech presentation itself may not be related to adverse pregnancy outcomes, and more attention is needed for further exploration.

背景
越来越多的研究发现臀位与既往疾病有关，可能影响未来胎儿发育。本研究旨在比较臀位和头位之间的差异，并探讨胎儿先露本身导致不良结局的潜在机制。
方法
检索“PubMed”“Embase”和“Cochrane图书馆”自建库至2022年10月21日的文献。纳入包含头位和臀位的“临产前剖宫产”或“选择性剖宫产”的比较研究。共纳入585项研究，5项研究符合最终研究标准。使用Review Manager 5.4.1进行数据合成。
结果
臀位组的死亡率与头位组无差异（RR 0.69，95%CI 0.09-5.13，P = 0.71）。臀位和头位之间在婴儿（<1岁）和新生儿（0-27天）死亡率方面未发现差异（RR 1.56，95%CI 0.86-2.82，P = 0.14）。然而，发现臀位组的出生体重（P < 0.002）、脐绕指数（P < 0.0001）和骨声速（P = 0.03）低于头位组。
结论
臀位本身可能与不良妊娠结局无关，需要进一步探索以引起更多关注。
