对１９９０、１９９３两年儿童营养监测与改善项目中的全国２７省１０１较贫困县儿童喂养状况进行了分析，母乳喂养率由６１．９％降至５４．１％，人工喂养率由５．７％升至１３．５％，婴儿开奶时间提前，１９９３年婴儿出生当天开奶人数增加了１２．７个百分点，母乳、混合喂养儿断奶时间分别提前５个月和１个月，六个月后七种（谷类、乳类、蛋类、鱼肉类、水果类、蔬菜类、豆类）辅食添加的人数１９９３年较１９９０年增加１０～３８个百分点，乳类辅食增加人数最多。母乳喂养儿营养不良患病率明显低于人工、混合喂养儿，未添加辅食的婴幼儿贫血率平均高于添加辅食组２９个百分点。

Rural preschool children′s feeding pattern of 101 poor sites in 27 provinces were analyzed from 1990 to 1993. The breast fed rate reduced from 61.9% to 54 1%. The bottle fed rate rose from 5.7% to 13.5%. The number of children starting breast fed on the delivery day increased by 12.7 per cent. The weaning time of breast and mixed fed was 5 months and 1 month earlier, respectively. The number of children adding 7 kinds of weaning food increased by 10～38 per cent.
