摘要
在北京宣武区(城区)和大兴县大皮营乡(农村)各选择25名新生健康婴儿,跟踪观察其在生后0～6月内的母乳、热能和蛋白质摄入量和体格的生长发育情况。结果表明:两组婴儿每日摄入母乳量平均为600～800g,农村婴儿母乳摄入量高于城区;婴儿的热能摄入量在生后的第1月为109kcal/kg体重,到第3和第6月分别为78和65kcal/kg体重;蛋白质摄入量在第1月时为2.1g/kg体重,以后则维持在1.5g/kg体重;两组婴儿的身长,体重和头围生长曲线在NCHS的25～75百分位,上臂周、三角肌和腹部皮褶厚度也都在正常范围内。以上结果说明:所调查的两组婴儿的体格生长正常,但其在3～6月期间摄入的热能和蛋白质则远低于我国或WHO/FAO(1973)的供给量标准,这与Whitehead所报告的发达国家的情况是一致的。说明现行的婴儿热能和蛋白质供给量标准可能过高。应适当降低。
A longitudinal study was carried out on fifty infants selected from both urban and rural areas of Beijing for their body weights, heights, head and mid-upper arm circumferences, tricep and abdomen skinfold thicknesses, and breatmilk and energy and protein intakes at the 1st, 3rd and 6th month of life. The results revealed that the breastmilk intakes of these infants were ranged from 600-800 g/day during this period of time, the breastmilk intakes of the rural infants were higher significantly than that of the urban infant throughout the study period (P<0.05 and P<0.01). The energy intakes calculated from both breastmilk and supplementary foods at the 1st, 3rd and 6th month were 109, 78 and 65 kcal/kg body weight and the protein intakes 2.1, 1.5 and 1.5 g/kg body weight per day respectively. Their body weights, heights and head circumferences were generally within the 25-75th percen-tile of the NCHS standards, and their mid-upper arm circumferences, tricep and abdomen skinfold thicknesses were also in the normal range. It indicated that, based on the present and other studies, the current recommendations for energy and protein intakes for the 0-6 months old infants might be too high, and that the recommendations for energy and protein intakes for infants within the 6 months of life should be reduced, that the energy intakes during the first 3 months of life being 110 kcal, during the 4-6 months 90 kcal and protein intakes being 2.0 g and 1.5 g per kg body weight per day respectively might reflect more accurately the real needs of the normal infants during this period of time.
