对１９８５～１９８９年７省较贫困的１８个乡农村儿童膳食调查资料采用平均摄入量、临界值及概率法进行了总结分析。结果表明，６～２４月龄母乳喂养儿的辅食品种单一，数量不足。断奶儿童各年龄组热能、蛋白质摄入量的平均值分别达ＲＤＡ的９２％～１０４％和７６％～８４％，但以ＲＤＡ为界值，仍有５３％～６２％及７４％～８５％的儿童热能、蛋白质摄入量低，用概率法分析蛋白质、钙、维生素Ａ、Ｂ２、Ｃ及铁摄入不足的人数比例分别是５０％～６０％、９３％～９７％、５１％～８７％、７４％～８６％、５８％～６６％和１２％～４７％。热能、蛋白质摄入量低于ＲＤＡ值儿童的身高、体重明显低于摄入量高于ＲＤＡ值的儿童。
The average dietary intake, the critical value and the probabilistic method were used to summarize the dietary survey data of 18 rural children from 1985 to 1989 in the poorer provinces of seven provinces. The results showed that breastfeeding children aged 6 to 24 months feeding a single, insufficient number of complementary foods. The average energy and protein intake of weanling children reached 92% ~ 104% and 76% ~ 84% of the RDA respectively, but with RDA cutoff, there were still 53% ~ 62% and 74% ~ 85% Of children had low caloric intake and protein intake. The probabilities of protein, protein, calcium, vitamin A, B2, C and iron intake were 50% -60%, 93% -97%, 51% -87 %, 74% -86%, 58% -66% and 12% -47%. Children with caloric and protein intakes less than RDA had significantly lower body weights than those with intakes higher than the RDA.
