The objective of this review is to evaluate the evidence for a link between maternal obesity and poor lactation performance. In nonhuman species, excess maternal fatness is deleterious for lactation and also for maternal health and survival. These effects occur during pregnancy and as milk production is beginning. They may result in poor growth and survival of the young. In women, there is a negative association between maternal obesity and the initiation as well as the continuation of breastfeeding. This appears to be derived from biological as well as sociocultural factors that are still poorly understood. Excessive gestational weight gain, complications of pregnancy and delivery, and the condition of the infant at birth may also contribute to this association. Given the increasingly high rates of obesity among women of reproductive age worldwide and the importance of breastfeeding for infant health, further study of this association is essential.

孕前孕产妇肥胖与泌乳性能差有关。

这篇综述的目的是评估孕产妇肥胖与不良泌乳性能之间存在联系的证据。在非人类物种中，过多的孕产妇脂肪对哺乳以及孕产妇的健康和生存有害。这些影响发生在怀孕期间和开始生产牛奶时。它们可能会导致年轻人生长不良和生存。在女性中，孕产妇肥胖与母乳喂养的开始和持续之间存在负相关关系。这似乎是由于生物学和社会文化因素仍不为人所知。妊娠体重增加过多，妊娠和分娩并发症以及婴儿出生时的状况也可能与这种关联有关。
