A Study on the Intake-Balance of Iron, Copper and Cobalt of College Women in Korea

한국 여자 대학생의 Iron, Copper 및 Cobalt 평형에 관한 연구

In this study measured were daily intake and excretion of iron copper and cobalt of eight 21-23years old college women during four weeks by means of analyzing their food intake urine and feces while keeping their normal living pattern and maintenace of body weight. this is study also compared the actural meaurement value of iron intake by atomic absorption spectrophotometry with the conversion value of it by food table. The results were as follows. Daily mean intakes for iron copper and cobalt were $13.85{\pm}1.10mg/day,\;1.44{\pm}0.14mg/day\;and\;3.25{\pm}0.18mg/day$. Daily mean urinary excretions for iron copper and cobalt were $1.38{\pm}0.27mg/day\;0.06{\pm}0.01mg/day\;and\;0.59{\pm}0.07mg/day$. Daily mean fecal excretions for iron cop-per and cobalt were $7.66{\pm}0.79mg/day\;0.59{\pm}0.11mg/day\;and\;0.94{\pm}0.16mg/day$ The actual measurement value for iron intake was $13.85{\pm}1.10mg/day$ and its conversith value $15.26{\pm}1.17mg/day$ : the former was 9% than the latter.

본 연구는 21~23세의 여자 대학생 8명을 대상으로 4주간 평상시와 같은 생활 양식과 적정 체중을 유지 시키면서 각 대상자들이 섭취한 모든 음식과 배설한 대변 및 소변을 수거하여 iron, copper 및 cobalt의 함량을 측정하여 1인 1일당 섭취량과 배설량을 측정하였다. Iron 섭취량은 원자 흡광광도계로 측정한 설측치와 식품 분석표에 의거하여 얻은 환산치와의 관계를 비교하였다. 그 성적을 요약하면 다음과 같다. 1일 1인당 각 대상자별 평균 섭취량은 iron $13.85{\pm}1.10mg/day,\;copper\;1.44{\pm}0.14mg/day\;그리고\;cobalt는\;3.25{\pm}0.18mg/day$이었다. 1일 1인당 각 대상별 소변으로의 평균 배설량은 iron $1.38{\pm}0.27mg/day\;copper\;0.06{\pm}0.01mg/day\;그리고\;cobalt\;0.59{\pm}0.07mg/day$이었다. 1일 1인당 각 대상자별 대변으로의 평균 배설량은 iron $7.66{\pm}0.79mg/day\;copper\;0.59{\pm}0.11mg/day\;그리고\;cobalt\;0.94{\pm}0.16mg/day$이었다. Iron의 실측치는 $13.85{\pm}1.10mg/day$이었고 환산치는 $15.26{\pm}1.17mg/day$로 실측치가 환산치에 비하여 9% 낮았다.
