The relative importance of dietary and familial factors in determining weight in early infancy were studied in 203 5-year-old children. Their age at weaning, energy intake in infancy and at 5 years, and maternal percentage expected weight were studied in relation to their percentage expected weight. Neither the estimated energy intake in infancy nor the intake at 5 years correlated significantly with their percentage expected weight at 5 years. Overweight 5-year-olds had not been weaned earlier than normal-weight 5-year-olds. There was a significant correlation between the percentage expected weights of the mothers and those of their children at 5 years of age, although the children of overweight mothers did not have higher energy intakes than the children of underweight mothers. A familial, perhaps genetically determined, tendency to overweight seems to be more important in determining whether a child will be overweight at 5 years old than early weaning and overfeeding in infancy.
在203名5岁儿童中研究了饮食和家庭因素在决定婴儿早期体重方面的相对重要性。研究了他们的断奶年龄、婴儿期和5岁时的能量摄入，以及母亲预期体重百分比与他们预期体重百分比的关系。婴儿期估计的能量摄入量和5岁时的摄入量与他们5岁时预期体重百分比均无显著相关性。超重的5岁儿童断奶时间并不比正常体重的5岁儿童早。母亲预期体重百分比与她们5岁孩子的预期体重百分比之间存在显著相关性，尽管超重母亲的孩子能量摄入量并不比体重过轻母亲的孩子高。在决定一个孩子5岁时是否超重方面，一种家族性的、可能由基因决定的超重倾向似乎比婴儿期过早断奶和过度喂养更重要。
