我国较贫困地区农村学龄前儿童膳食状况

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。

Dietary status of preschool children in relatively poor rural areas of China

Dietary survey data of rural preschool children of 18 relatively poor areas in 7 provinces were collected from 1985 to 1989 and analyzed by using average intake, cut off point and probability approaches. The results showed that the complementary foods of 6～24 months old bresat-fed children were monotonous and inadequate. The average rate of energy and protein intake of 1～5 years old children after weaning reached 0. 92～1. 04 and 0. 76～0. 84 compared with Chinese RDA respectively. The energy and protein intake in 53%～62% and 74%～85% of children was lower than RDA value. The proportion of children with inadequate protein,calcium, vitamin A, vitamin B2, vitamin C and iron intake were 0. 50～0. 60, 0. 93～0. 97, 0. 51～0. 87, 0. 74～0. 86, 0. 58～0. 66 and 0. 12～0. 47 respectively by using the probability approach. The height and weight of children whose energy and protein intake below the RDA value were significantly lower than those of the children with the energy and protein intake higher than the RDA.
