모유영양아와 인공영양아의 피하지방 및 상완위의 성장발육 상태 : 영아의 피하지방 및 상완위 발육상태 = Skinfold Thickness and Arm Circumference of Korean Breast Fed and Formula Fed Infants from 1 to 3 Postpartum Months

다국어 초록 (Multilingual Abstract)

One- to three- month-old infants (n=232) were compared their upper arm cumference and skinfold thickness(triceps, subscapular) by feeding methods in cross-sectional study. There were two groups : breast-fed(BF) and formula-fed groups(FF). As reported previously^(7)), weight, length, head and chest circumferences of these infants were good, and overall growth status was not significantly different by feeding methods, but weight, weight velocity and chest circumference of formula-fed infants were higher than breast-feds at 3 month, significantly.
Here, the triceps skinfold thickness of infants at 1, 2, and 3 postpartum months were 7.4, 9.5 and 10.5 ㎜, respectively. The triceps skinfold thickness of breast-fed infants were higher than formula-feds at 1 and 2 postpartum month, but at 3 month, that of formula-fed infants was greater than breast-fed infants, insignificantly. The subscapular skinfold thickness of infants were 6.4, 9.2 and 10.6 ㎜ at 1 to 3 postpartum months, respectively.
The upper arm circumference of infants were 11.7, 13.4, 14.3㎝, and the arm muscle diameter were 34.5, 39.3 and 41.7㎝ at one to three postpartum months, respectively. The upper arm circumference of male infants was higher than females at 2, 3 postpartum months.
Overall, there were no significant differences between feeding methods in triceps and subscapular skinfold thickness, upper arm circumference and arm muscle diameter. But 3-month-old formula-fed male infants showed bigger significantly in arm circumference than the breast-feds.
From this survey, long-term survey on growth and body composition of large scales might be necessary to determine the effect of feeding methods of infants after 3 months and to set proper body composition standard for infant.
