摘要
目的 : 了解我省汉、苗、布依族儿童先天和后天的营养状况和体格发育 ,寻找对儿童体格发育影响最主要的因素。方法 : 对母亲在妊娠中、晚期及儿童出生后至 6岁进行膳食调查 ,身高、体重的测量及环境因素的调查。结果 : 苗族组、布依族组居住环境和生活条件较差。汉、布依、苗族三组在母亲妊娠中、晚期蛋白质、钙、VB2 摄入量不足 ,未达到 RDA80 %。苗族组 2～ 4岁蛋白质摄入量均在 RDA80 %以下。苗族组、布依族组蛋白质的摄入多以谷类蛋白为主。三组各年龄段普遍存在钙、VB2 摄入量的不足。从生长曲线看 ,小儿出生后至 3个月的身长、体重各组基本与标准接近或超过标准。但随着年龄增长 ,布依族组和苗族组从 3～ 4月起就逐渐与标准有差别 ,差别最大的是苗族组 ,6岁时身高已相差 9.8cm(男 ) ,8.3 cm(女 ) ,体重相差 1 .6 4 kg(男 ) ,1 .92 kg(女 )。结论 : 布依族、苗族组的体格发育差于汉族组 ,身材较矮小。在环境因素的影响中 ,蛋白质的质和量对体格发育起着重要作用。
Objective: To investigate the childrens congenital and acquired nutritional status and the physical development among the different nationalities in Guizhou province; to find out the factors that greatly influence the childrens physical development. Methods: Investigations were carried out on the diet, height and the weight of the mothers during the early and late stage of their pregnancy and after the delivery of the babies. Results: The living conditions in the groups of Miao and Buyi were very poor. For the pregnant women among Han, Miao and Buyi groups, during their middle and late stage of the pregnancy, the intakes of protein, calcium and VB 2 did not reach 80% RDA. For the 2-4 years old children, the intake of protein was below 80% RDA. For those in Miao and Buyi groups, the chief source of protein was from cereals. There was a great insufficient intake of calcium and VB 2 in different age groups of the children mentioned above. With the increase of age, the infants of Buyi and Miao groups were gradually diverting from the standard criterion from 3rd or 4th month. The greatest difference was in Miao group, i.e. at the age of 6, the difference in height was 9.8 cm(male), 8.3 cm(female); the difference in weight was 1.64 kg(male), 1.92 kg(female). Conclusion: The physical development of the infants in Buyi and Miao groups is inferior to those in Han group. Besides the environmental influence, the quality and quantity of the protein in diet play an important role in physical development.
