산업체 근로자의 potassium 섭취상태와 배설상태를 평가하기 위하여 서울시내 H타이어 공장에 근무하는 건강한 성인남자 40명을 대상으로 3일간 식사 분석과 뇨 분석을 행하였다. 대상자들의 3일동안 평균 potassium 섭취량은 $54.5pm16.7mEq/day(2.13pm0.64g)$이었고, 24시간동안 뇨 중의 potassium 배설량은 $45.9pm10.5mEq/day(1.77pm0.41g)$로 소변중 배설은 83%정도였다. Na와 K의 섭취비율은 $4.15pm0.58$인 반면에, 뇨 중 배설비율은 $5.20pm1.11$이었다. 1일 섭취하는 potassium의 주요 급원은 밥 중에서 콩 밥, 국 종류에서는 감자된장국, 반찬류에서는 삼치무조림과 묵야채무침이었다. 단백질 섭취량과 K 섭취랑, N 배설량과 K 배설량, N 배설량과 Na 배설량, K 섭취량과 Na 섭취량, 그리고 K 배설량과 Na 배설량간에 모두 유의적인 상관을 나타내었다.
This study was undertaken to evaluate the potassium consumption and excretion in forty healthy male workers of a tire company in Seoul. Mean postassium intake for three days in the subject was $54.5pm16.7mEq/day(2.13pm0.64g)$ and urinary excretion of potassium in 24 hours was $45.9pm10.5mEq(1.77pm0.41g)$. Thus 83% of dietary potassium was excreted in the form of urine. Dietary ratio of Na to K was $4.15pm0.58$ while urinary ratio of Na to K was $5.20pm1.11$. The main food source of potassium was cooked rice with soybean in the rice group, potato with soybean paste soup in the part of soup group. and seasoned Spanish mackerel with raddish in the side dish group. There was a strong correlation between dietary protein and dietary potassium(r=0.694, p<0.001). Urinary sodium and potassium were also strongly associated with each other(r=0.647, p<0.001).
