Animal and human studies indicated that inadequate diet for a prolonged period during pregnancy could injure mother, child, or both. In order to prevent this problem, maternal nutyitional status during pregnancy is very important and the evaluation of nutrition during pregnancy have been preceded by many authors in another countries. In Korea, nutrient intake studies of the pregnant women and nutrition surveys in adult by biochemical method have been performed, but there are no data nutrition surveys of Korean pregnant women have been made by biochemical method. In this regard, an exact biochemical titer of the nutrients and the degree of nutrient deficits in Korean pregnant women are needed. In this study, the mean titer of some nutrients and the degree of nutrient deficits by biochemical method in Korean pregnant women
were assessed. The objected materials were consisted of 30 cases which had visited the departmant of Obstetrics & Gynecology, Chung Ang University Hospital for antenatal care(32wk-40wk) from March, 1981 to June, 1981. The cases with twin pregnancy, and the cases complicated with materal chronic wasting disease, diabetes, hydroamniosis, hypertensive disorder in pregnancy were excluded in this study. The results were as follows: 1. Mean titer of 6 hours urine execretion of thiamine, riboflavin and N’-methylniacinamide in Korean pregnant women was 44㎍, 466㎍, and 2.33㎎. 2. Mean titer of serum vitamin A, carotene, vitamin C, total protein, calcium, phosphorus, iron and total lipid was 48.1㎍, 154.7㎍, 0.8㎎, 7.0g, 9.8㎎ 3.5㎎, 93㎍, and 578㎎. 3. Percentage of nutrient deficits in Korean pregnant women based on the mean titer of Korean adults was as follow; thiamine-20%, N’-methylniacinamide-7%, total protein-5%, calcuim13%, iron-19%. 4. No cases were deficient in riboflavin, carotene, phosphorus, total lipid and the mean titer of riboflavin and carotene in Korean pregnant women were high compared with thw mean titer of Korean adults.
