A cross-sectional study of 58 infants (age range 2-53 weeks) was carried out in a rural area of northern Thailand. Total dietary intake (energy and protein from breastmilk and supplementary food) was measured directly during continuous observation over 48 h of randomly selected study subjects in their homes. Associations between infant weight and total energy intake, total protein intake and morbidity were analysed by multiple regression analysis. Up to 6 months of age, heavier infants had larger energy intakes, when age and birthweight were taken into account. In the 7-12 months age group, heavier infants consumed more protein and had fewer respiratory infections. Weaned infants older than 6 months were significantly heavier and consumed more protein than infants of similar age who were still receiving breastmilk. The lower protein intakes of the latter infants were due to the low protein concentration of breastmilk compared with supplementary food.
在泰国北部的一个农村地区，对58名婴儿（年龄范围为2至53周）进行了一项横断面研究。在随机选择的研究对象家中连续观察48小时期间，直接测量了总膳食摄入量（母乳和辅食中的能量和蛋白质）。通过多元回归分析，分析了婴儿体重与总能量摄入量、总蛋白质摄入量和发病率之间的关联。在考虑年龄和出生体重的情况下，6个月以下的较重婴儿能量摄入量更大。在7至12个月年龄组中，较重婴儿摄入的蛋白质更多，呼吸道感染更少。6个月以上的断奶婴儿比仍在接受母乳喂养的同龄婴儿明显更重，摄入的蛋白质更多。后一组婴儿蛋白质摄入量较低是因为与辅食相比，母乳中的蛋白质浓度较低。
