This review uses the 1990 U.S. Institute of Medicine (IOM) gestational weight gain recommendations to examine the question, what is a healthy pregnancy weight gain? The relationship of gestational weight gain to infant size at birth; pregnancy, labor, and delivery complications; neonatal, infant, and child outcomes; and maternal weight and health outcomes in U.S. and European populations are discussed. Pregnancy weight gains within the IOM recommendations are associated with better outcomes. The possible exception is very obese women, who may benefit from weight gains less than the 7 kg (15 pounds) recommended. Only about 33% to 40% of U.S. women gain within IOM recommendations. Excessive gestational weight gain is more prevalent than inadequate gain. Women's gestational weight gains tend to follow the recommendations of health care providers. Current interventions demonstrate efficacy in influencing gestational weight gain in low-income women with normal and overweight body mass index in the United States and obese women in Scandinavia.

在怀孕期间实现健康的体重增加。

这篇综述使用了1990年美国医学研究所（IOM）的妊娠体重增加建议来研究以下问题：什么是健康的孕妇体重增加？妊娠期体重增加与婴儿出生时体重的关系；怀孕，分娩和分娩并发症；新生儿，婴儿和儿童的结局；并讨论了美国和欧洲人口的孕产妇体重和健康状况。IOM建议中的怀孕体重增加与更好的预后相关。可能的例外是非常肥胖的妇女，她们的体重增加可能少于建议的7千克（15磅），他们可能会因此受益。在IOM建议范围内，只有约33％到40％的美国女性受益。妊娠体重增加过多比体重增加不足更为普遍。妇女的妊娠体重增加往往遵循医疗保健提供者的建议。
