Abstract

Purpose : This study was conducted to evaluate the red cell indices and frequency of iron deficiency anemia based on the feeding patterns of nine-month-old infants. Methods : Blood tests were performed on 253 nine-month-old infants, who visited Il Sin Christian Hospital for health check-ups from January to December 2007. Their parents answered telephonic questions regarding their feeding patterns and weaning foods. Results : Three infants groups were created according to feeding patterns before they started weaning foods. One group was exclusively breast-fed (48.6%), another had mixed feeding (27.3%), and the third had artificial milk feeding (24.1%). Red cell indices (hemoglobin, hematocrit, MCV, MCH) of the breast-fed group were comparatively lower than those of the other two groups (P<0.05). Twenty-five infants (9.9%) were diagnosed with iron-deficiency anemia. According to feeding patterns, the frequency of anemia was highest in the breast-fed group. Six infants who started weaning foods before six months of age (113 infants) were diagnosed with iron-deficiency anemia (5.3%), and nineteen who started after six months of age (140 infants) were diagnosed with iron-deficiency anemia (13.6%). Conclusion : When nine-month old infants visit hospitals for health check-ups, pediatricians must consider their feeding pattern and weaning foods histories, and then recommend screening blood tests for iron-deficiency anemia.

목 적 : 9개월 영아의 수유방법에 따른 철결핍빈혈의 빈도와 적혈구 혈액상을 알아보고자 이 연구를 시행하였다. 방 법 : 2007년 1월부터 12월까지 생후 9개월의 특이병력이 없는 영아 253명의 혈액검사를 시행하고 부모를 대상으로 수유방법과 이유식에 대한 설문조사를 하여 결과를 얻었다. 결 과 : 총 253명 중 모유수유 123명(48.6%), 혼합수유 69명(27.3%), 인공수유 61명(24.1%)였다. 수유방법에 따른 적혈구 혈액상은 모유수유군에서 혼합수유군이나 인공수유군에 비하여 유의하게 낮았다(P<0.05). 253명 영아 중 25명에서 철결핍빈혈로 판명되어 9.9% 빈도를 보였고 수유방법에 따라서는 모유수유군에서 18.7%, 혼합수유군에서 1.4%, 인공수유군에서 1.6%의 빈도를 보여 모유수유군에서 빈혈 발생빈도가 유의하게 높았다(P< 0.05). 이유식 시작 시기에 따른 철결핍빈혈의 빈도는 생후 6개월 이내에 이유식을 시작한 영아 113명 중 6명(5.3%), 6개월 이후에 이유식을 시작한 영아는 140명 중 19명(13.6%)로 이유식을 늦게 시작한 군에서 철결핍빈혈의 빈도가 유의하게 높았다(P<0.05). 결 론 : 생후 9개월의 영아가 내원하였을 때 수유 방법이나 이유식에 대한 문진을 통하여 철분 등을 포함한 영양 상태에 관하여 알아보고 선별적 빈혈 검사를 통하여 철결핍빈혈의 예방과 치료에 힘써야 할 것이다.
