Abstract

Purpose: Iron deficiency anemia (IDA) is one of the most common nutritional problems, despite a recent improvement of nutritional status of infants and children. We assessed the risk factors for IDA in infants and vitamin D deficiency and IDA by nutrition analysis. Methods: We analyzed blood tests and evaluated 103 children with IDA and 123 children without IDA, 6-36 months of age, who were cared for in our hospital between March 2006 and July 2010. Nutritional analysis using Canpro was performed among breastfed infants 6~12 months of age who had been diagnosed with IDA and had detailed diet histories. Results: Breastfed infants accounted for 87.4% and 40.7% of the IDA and comparison groups, respectively. The IDA and comparison groups began weaning food at 6.4${\pm}$1.8 and 5.9${\pm}$1.3 months, respectively. In the IDA and comparison groups, 46.4% and 53.5% began to adapt to weaning food within 4 weeks, respectively. The most common reason for hospital care of the IDA group was respiratory symptoms constituting 36.2%. Only 18.6% visited the hospital for palloror anemia. The Canpro analysis, performed on 11 infants with IDA, showed that iron and vitamin D were <40% and 30% of recommended intakes, respectively. Conclusion: Weaning food should be started 4~6 months of age in breastfed infants. In infants at high risk for IDA and vitamin D deficiency, screening tests should be recommended. The high-risk infants may require iron, vitamin D fortified formula, or oral supplements.

목 적: 철결핍성 빈혈(iron deficiency anemia, IDA)은 영양상태의 개선에도 불구하고 여전히 발견되는 영양질환이다. 저자들은 영유아기에 IDA가 발생할 수 있는 위험 인자에 대해 알아보았고, IDA 환아의 영양 분석을 통하여 철분 및 비타민 D 영양 결핍에 대하여 알아 보았다. 방 법: 2006년 3월부터 2010년 3월까지 저자들의 병원에 내원한 6~36개월의 IDA 환아 103명을 대상으로 하였고, IDA가 없는 같은 연령의 영유아 123명을 비교군으로 혈액검사와 설문 조사를 하였다. IDA가 진단된 6~12개월 환아 중 식이력 작성이 구체적인 11명에 대해서는 Canpro를 이용하여 영양 분석하였다. 결 과: IDA군에서 모유수유 87.4%, 비교군에서는 모유수유 40.7%였다. 이유 시작 시기는 IDA군은 평균 6.4${\pm}$1.8개월이었고 비교군은 평균 5.9${\pm}$1.3개월이었다. 이유식을 잘 먹게 된 시기는 IDA군에서 4주 이내는 46.4%, 비교군에서 4주 이내는 53.5%였다. IDA군의 병원 방문 이유는 호흡기 질환이 36.2%로 가장 많았고, 빈혈 증상으로 방문한 경우는 18.6%였다. IDA 환아 11명의 Canpro 분석에서 철분은 권장섭취량의 40% 미만이었고, 비타민 D 섭취는 30% 미만이었다. 결 론: 모유수유를 하는 영아는 4~6개월에 이유식을 시작해야 한다. 위험 인자가 있는 영아에서 철결핍 빈혈과 비타민 D 결핍이 있을 수 있으므로, 선별검사와 비타민 D 영양 평가가 필요하다. 또한 철분강화 분유, 비타민 D 강화 분유나 이유식을 통한 영양 공급이 필요하다.
