In July 1990, new guidelines for nutrition during pregnancy were published by the National Academy of Sciences. The Subcommittee on Weight Gain During Pregnancy revised the weight gain recommended for pregnancy. During the process of developing new recommendations, the subcommittee considered several factors that might help to determine the appropriate weight gain for an individual pregnant woman. Some of these factors include demographic and biological changes that might influence the effect of weight gain. Clinical issues that must be considered in implementing the weight gain recommendations include the importance of accurate weight and height measurement, categorizing the woman's weight for height, determining rate of gain at different times during pregnancy, and evaluating the significance of deviations from the expected weight gain pattern. A review of prior studies reveals that body composition changes, which might be important to consider in conjunction with weight changes, have not been well studied. Data are presented from a current study that indicates the problems encountered if traditional methods of body composition measurement are used during pregnancy.
1990年7月，美国国家科学院发布了孕期营养新指南。孕期体重增加小组委员会修订了孕期推荐的体重增加量。在制定新建议的过程中，该小组委员会考虑了几个可能有助于确定个体孕妇适当体重增加量的因素。其中一些因素包括可能影响体重增加效果的人口统计学和生物学变化。在实施体重增加建议时必须考虑的临床问题包括准确测量体重和身高的重要性、根据身高对女性体重进行分类、确定孕期不同阶段的体重增加率，以及评估偏离预期体重增加模式的意义。对先前研究的回顾表明，身体成分变化可能与体重变化一并考虑很重要，但尚未得到充分研究。本文给出了一项当前研究的数据，该数据表明在孕期使用传统身体成分测量方法会遇到的问题。
