To obtain a better understanding of the changes in feeding behaviour from 1 to 6 months of age. By comparing breast- and bottle-feeding, we intended to clarify the difference in longitudinal sucking performance.
Sucking variables were consecutively measured for 16 breast-fed and eight bottle-fed infants at 1, 3 and 6 months of age.
For breast-feeding, number of sucks per burst (17.8 +/- 8.8, 23.8 +/- 8.3 and 32.4 +/- 15.3 times), sucking burst duration (11.2 +/- 6.1, 14.7 +/- 8.0 and 17.9 +/- 8.8 sec) and number of sucking bursts per feed (33.9 +/- 13.9, 28.0 +/- 18.2 and 18.6 +/- 12.8 times) at 1, 3 and 6 months of age respectively showed significant differences between 1 and 6 months of age (p < 0.05). The sucking pressure and total number of sucks per feed did not differ among different ages. Bottle-feeding resulted in longer sucking bursts and more sucks per burst compared with breast-feeding in each month (p < 0.05).
The increase in the amount of ingested milk with maturation resulted from an increase in bolus volume per minute as well as the higher number of sucks continuously for both breast- and bottle-fed infants.
更好地了解 1 至 6 个月龄时喂养行为的变化。通过比较母乳喂养和奶瓶喂养，我们旨在阐明纵向吸吮性能的差异。
连续测量 16 名母乳喂养和 8 名奶瓶喂养婴儿在 1、3 和 6 个月时的吸吮变量。
对于母乳喂养，每口爆发的吮吸次数（17.8 +/- 8.8、23.8 +/- 8.3 和 32.4 +/- 15.3 次）、吮吸爆发持续时间（11.2 +/- 6.1、14.7 +/- 8.0 和 17.9 +/- 8.8 秒）和每次喂养的吮吸爆发次数（33.9 +/- 13.9、28.0 +/- 18.2 和 18.6 +/- 12.8 次）在 1、3 和 6 个月龄时分别显示出 1 个月龄和 6 个月龄之间的显著差异（p < 0.05）。吸吮压力和每次喂养的总吮吸次数在不同年龄之间没有差异。与母乳喂养相比，奶瓶喂养在每个月的吮吸爆发时间更长，每次吮吸的次数更多（p < 0.05）。
随着成熟，摄入的牛奶量增加，这是由于每分钟奶量的增加以及两种母乳喂养和奶瓶喂养婴儿连续吮吸次数的增加所致。
