A major challenge facing the health care system is to improve the distribution of infant birth weights. Prenatal weight gain and prepregnancy weight status are two of the major factors that influence infant birth weight. These are independently and linearly related to birth weight. It is believed by many that the distribution of infant birth weights may be improved by implementing prenatal weight gain goals that optimize the relationship between prepregnancy weight status and infant birth weight. The panel considered prenatal weight gains for underweight and normal weight women that correspond to the delivery of infants with birth weights within a desired range. The panel identified (a) the desired range of birth weights as 3,500 to 3,999 grams; (b) for underweight women starting pregnancy, a prenatal weight gain of 30 to 35 pounds (lb), plus the prepregnancy weight deficit for the height of the woman; and (c) for normal weight women starting pregnancy, a gain of 30 to 35 lb. The report summarizes the scientific rationales for the conclusions, as well as the results of deliberations on potential risks to maternal health of the suggested weight gains.
医疗保健系统面临的一个主要挑战是改善婴儿出生体重的分布情况。孕期体重增加和孕前体重状况是影响婴儿出生体重的两个主要因素。它们与出生体重呈独立的线性关系。许多人认为，通过实施孕期体重增加目标，优化孕前体重状况与婴儿出生体重之间的关系，可以改善婴儿出生体重的分布。该小组考虑了体重过轻和体重正常的女性的孕期体重增加情况，这些增加量应能使婴儿出生体重处于理想范围内。该小组确定：(a) 理想的出生体重范围为3500至3999克；(b) 对于孕前体重过轻的孕妇，孕期体重增加30至35磅，再加上根据孕妇身高计算出的孕前体重不足量；(c) 对于孕前体重正常的孕妇，体重增加30至35磅。该报告总结了得出这些结论的科学依据，以及关于建议的体重增加量对孕产妇健康潜在风险的审议结果。
