上海市中福会国际和平妇幼保健院１９９３～１９９４年门诊产前检查确定为怀孕的２０００名妇女，从妊娠开始进行追踪调查，到分娩正常出生体重的活婴为止。观察项目包括，膳食调查３ｄ记录法，孕妇孕前及孕期体格检查，新生儿体格检查，并根据孕前体重、身高，计算孕前身体质量指数（ＢＭＩ）。根据ＢＭＩ不同，将孕妇分为４组。结果分娩正常出生体重婴儿的孕妇，孕期总增重平均为１５ｋｇ，较以往１２ｋｇ有较大的提高。孕早期体重增加很少，至孕１５ｗ不足２ｋｇ，从孕１７ｗ起，增重明显。孕中期平均每周增重０．２～０．９ｋｇ，孕晚期为０．４～０．８ｋｇ，孕中与孕晚期各周增重均无明显差别，与孕晚期增重高于孕中期的看法尚不一致。不同的ＢＭＩ４组孕妇间，孕期增重水平并无显著性差别，而婴儿出生体重随孕前ＢＭＩ的增大而增加，有统计学意义。此外本次调查发现，ＢＭＩ＜１９．８，１９．８～２６．０，２６．０～２９．０间的３组孕妇，其孕期营养素摄入水平并无明显差别。
