Diurnal feeding behavior of 24 exclusively breast-fed infants was examined at 2, 4, 6, 8, and 12 weeks to assess whether milk intake at a feeding was related to previous (preprandial) or subsequent (postprandial) intervals between feedings. Amount of human milk consumed per feeding and intervals between feedings were measured over a 72-hr period. Correlation analyses revealed that volume of milk ingested at a feeding (meal size) was positively related to preprandial interval at all 5 ages (r = 0.39-0.47, p less than 0.0001). Meal size was likewise related, but not as strongly, to postprandial interval at 4 of the 5 time points examined (r = 0.17-0.25, p less than 0.01). Results of the correlational analyses revealed clear, consistent preprandial correlations, providing evidence for a reactive type feeding pattern among the solely breast-fed infants. Postprandial correlations, possibly reflect an anticipatory feeding pattern, were present but remained consistently low over the 3 months examined, providing little evidence of a developmental shift. This study provides a preliminary foundation for future longitudinal studies that address the regulation of food intake among infants.
对24名纯母乳喂养婴儿在2周、4周、6周、8周和12周时的日间喂养行为进行了检查，以评估一次喂养时的奶量摄入是否与之前（餐前）或之后（餐后）的喂养间隔有关。在72小时内测量每次喂养摄入的母乳量和喂养间隔。相关分析显示，在所有5个年龄段，一次喂养时摄入的奶量（餐量）与餐前间隔呈正相关（r = 0.39 - 0.47，p < 0.0001）。在所检查的5个时间点中的4个，餐量与餐后间隔也有关系，但相关性没那么强（r = 0.17 - 0.25，p < 0.01）。相关分析结果显示出清晰、一致的餐前相关性，为纯母乳喂养婴儿中一种反应型喂养模式提供了证据。餐后相关性可能反映了一种预期性喂养模式，虽存在但在整个3个月的检查期间一直很低，几乎没有发育转变的证据。本研究为未来解决婴儿食物摄入调节问题的纵向研究提供了初步基础。
