North Korea has been experiencing a serious food shortage. However, the extent and magnitude of malnutrition and health problems are virturally unknown because a nationwide food and nutritional survey has never been conducted. To get a better udnerstanding of the situation., an exhaustive literature search on the health and nutritiona conditions of North Koreans was performed. We also obtained anthropometric data on 274 North Korean Defectors who are recently resettlers in the South. Some(137) measurements were taken at the time of entry to the South, and the remaining data was from the health and nutrition mail survey conducted by us on North Korean refugeee re-settlers. Health and inutritional status of North Koreans was found to be less than desirable as shown in high infant mortality rates, high mortality and morbidity rates of malnutriton-related infectious deseases, and smaller body sizes. Striking differences were noted in all of the above health and nutrition indicators between north and South Koreans. Considering the fact that North and South Koreans are homogeneous in their genetic back-ground, ours study results clearly demonstrate that the health and nutrition of North Koreas has deteriorated with the dhronic food shortage, which might have sorsened with a recent food crissi. The smaller and thinner adult stature proevailing in North Korea could play a significant negative role in the country's economy, since lower lean body mass has been associated with reduced work productivity that could hinder economic growth and development.

Purpose: The purpose of this study was to explore the perimenstrual discomforts and dietary intake levels among normal women. Method: A prospective and descriptive study examined 38 women aged 23 46years of age. The data collection period lasted from April 1 to June 30, 2003. The participants were asked to keep a diary recording perimenstrual symptoms and food intake for 50 days. Results: There was a significant difference in physical symptoms of perimenstrual discomforts (F=6.95. p=.001). but there was no significant difference in dietary intake level according to three different phases of a menstrual cycle. The significant dietary intake variables correlated to PMS included energy, protein, Vitamin E, Vitamin $B_2$, niacin, Vitamin $B_6$, folic acid, phosphorus, iron, and zinc. They were negatively related to perimenstrual discomforts. Conclusion: Balanced diet intake will be necessary for not only the perimenstrual discomforts but also the general health promotion of the entire population. The dietary and nutritional assessment should be done prior to nursing interventions, and nutritional counseling and education should be given based on individual differences. In a further study, the effects of dietary composition on specific symptoms will be replicated with a large sample, and development of a diet intervention program for perimenstrual discomforts is recommended.

The aim of this study was to assess the nutrient intakes of the elderly subjects in Korea. Dietary assessment was carried out using a semi-quantitative food frequency questionnaire (SQFFQ) developed by our laboratory, which included 98 commonly consumed food items selected from 1998 National Health and Nutritional Survey for Korean population. Subjects (n = 2,660) aged 50yr and over were recruited in Seoul, 6 metropolitan cities, and 8 mid-size cities. Calcium and riboflavin intakes of the elderly subjects aged 65 yr and over (n = 1,974) were much lower compared with Korean RDA. Nutrient intakes of the three age group (50-64 yr, 65-74 yr, 75 yr and over) were decreased as age increased in male and female elderly. Nutrient intakes of male elderly, 75 yr and over, were significantly decreased while in female elderly nutrient intakes were gradually decreased as age increased. Over 30% of the elderly subjects did not meet 75% RDA for calcium, iron, vitamin A, and riboflavin. The proportion of the elderly subjects whose intakes were below 75% RDA was much higher than the elderly whose intakes were above 125% RDA, especially among the elderly aged 75 yr and over. This study revealed that the Korean elderly had inadequate intakes for many nutrients. This will cause a serious nutritional problem for the elderly.

To evaluate iron nutritional status and to compare biochemical indices used for evaluation of iron nutriture, fasting blood sample was taken from 96 Korean female college student and hemoglobin(Hb) concentration, hematocrit(Hct), serum iron, total iron binding capacity(TIBC) and serum ferritin concentration were measured and transferrin(TF) saturation was calculated. Prevalence of iron deficiency varied from 4.2% when judged from Hb concentration and Hct to 38.5% and 40.6% when TIBC and serum ferritin concentration were used. TIBC was negatively correlated with serum ferritin(r=0.4561, p<0.001), while other indices showed positive but less significant correlations(p<0.05). Regarding iron status judged by serum ferritin was regarded as true iron status, the present cutoff points of Hb, Hct, serum iron, TF saturation were very insensitive in identifying the subjects with iron deficiency. Only TIBC was suitable for detecting iron deficiency in the study subjects. It is concluded from the study results that iron deficiency in young Korean adult women would be significantly underestimated with presently used biochemical measurements except TIBC and new cutoff points of these indices were proposed based on sensitivity, specificity measured prevalence, and positive and negative predictive values.

Purpose: This study was done to identify menstrual discomfort and dietary habits, and factors related to the menstrual discomforts. Method: Participants were 320 female middle school students in G city. The Menstrual Discomfort Questionaire(MDQ) and dietary habit lists were used as tools. Results: Factors related to MDQ were found to be the VAS scores (r=.361, p=.002), a mount of menstrual bleeding (r=.131, p=.019), height (r=.134, p=.016), adequacy of meal time (t=7.19, p=.008), consumption of milk & milk products (F=3.20, p=.042) and, hot, salty & irritant foods (f=8.01, p=.000), eating more than 3 kinds of side-dishes with each meal (F=8.32, p=.000), and various protein foods (F=5.15, p=.006). In stepwise regression, 4 variables (VAS scores, height, hot, salty & irritant foods, more than 3 kinds of side-dishes with each meal) explained $20.3\%$ of the variance in the total MDQ scores. Conclusion: Reduction of hot, salty & irritant foods and having more than 3 side-dishes with each meal would be effective in menstrual discomfort management. As well, good and, balanced dietary habits should be encouraged for early adolescent girls. To keep up with the ideal dietary habits, nutritional education & counseling should be continued. In a further study, a replication study with larger samples and more specified nutritional assessment are recommended.

The develop a simple screening test for identifying Korean elderly at risk of undernutrition, the data of the health-related habits, dietary behaviors and nutrient intakes of the elderly in Chongju were analyzed. Two risk indicators, mean adequacy ratio (MAR) and the respondents perceived health, were used to detect the undernutrition risk of the elderly. In order to select a list of questions for the test, factors a affecting nutritional status and items investigated in previous nutrition surveys of the elderly were considered, and 21 questions were primarily selected. A multiple regression and stepwise regression analysis were used to take out the weak predictors of poor nutrient intake, and to give item weights to the strong predictors, and a list of 17 questions was finally adopted. To determine the cut-point of the test score, sensitivity, and positive predictive values were calculated. The Simple Screening Test developed in this study is a brief, easily scored tool to predict poor nutrient intake and the perceived health status of the elderly. The test may provide a basis of further comprehensive nutritional assessment or intervention planning, if necessary, for those who are diagnosed ad "high risk". The test, however, needs to be independently validated by other groups of individuals.dividuals.

How to appropriately apply the theories of oriental diet therapy in terms of direction and development are pressing concerns. To address these concerns, this study was performed to provide basic ideas to further the understanding oriental medicinal cuisine(Yack-Sun) and aid its application. Presently, basic data on the nutritional composition and oriental diet therapy area approach of Reajerksodo-tang was acquired to predict the usefulness of Reajerksodo-tang as an edema-related diuretic to promotes urination, drains heat and leaches out dampness. Reajerksodo-tang energy was 67.3 kcal per 100 g, crude protein was 77.2 g, crude fat was 5.7 g, crude ash was 0.6 g and carbohydrate was 16.5 g per 100 g. This basic data could help guide the application of oriental medicinal resources into other foods and serve as a stepping-stone for use of Reajerksodo-tang in the burgeoning field of function foods. Lastly, the scientific effects of oriental medicinal foods developed according to oriental medicinal theory. It is believed to be essential for government policy development concerning validation of medicinal effects and assessment, with the aim of fostering systematic development and providing guidance to food development in the interest of national health.

This study was peformed to assess the nutritional status of female nursing home residents by dietary intake. The subjects were 60 nursing home residents aged over 60 from 3 different nursing homes in Seoul, Cheonan and Chunchon. Dietary intake was assessed by 24-hr recall and nutrient intake was calculated using CAN-Pro and database for vitamin E established by authors. To establish vitamin E database, we analyzed vitamin E concentration using HPLC in several foods consumed frequently by nursing home residents. The results of nutrient intake were as follows; 1) Average daily intakes of energy, protein, phosphorous, iron, vitamin $B_1$ and niacin were higher than RDA, but calcium, vitamin $B_2$ and niacin of Chunchon were lower than RDA. 2) Intakes of protein, sodium and niacin of Cheonan residents were significantly higher than those of Seoul. 3) Intakes of phosphorous, potassium, vitamin $B_1$ and dietary fiber of Cheonan residents were significantly higher than Seoul and Chunchon. 4) Intakes of sodium and cholesterol of Seoul residents were higher than Cheonan and Chunchon. 5) Average daily intake of vitamin E was lower than RDA. Especially vitamin A intake of Cheonan residents was significantly lower than other two cities.

The Relative weight index is an index for evaluating nutritional condition of fish by calculating a ratio of observed weight to standard weight. The purpose of this study is estimating standard Length-Weight relationships (standard LWRs) to calculate standard weight for application of relative weight index and analyze frequency distribution of relative weight index of 10 freshwater fish in the South Korea. The standard LWRs for each species was calculated by the Length-Weight data sets from 798 times of captures at 141 sites. The correlation of determination (r²) for all species was over 0.9 and values of parameter b were within the expected range according to Froese (2006). We calculated in increments of 10 from 10 to 90 percentile of relative weight index for each species, and it could be used as a standard for quantitative assessment of nutritional condition of freshwater fish.

In Korea, there has been a rapid increase in the number and proportion of elderly people, especially in rural areas, due to improvements in the standard of living and medical technology. One of the main health problems for the elderly people is dental health, which can cause nutritional and health problems. Thus, in this study, the dental health status and health status in relation to nutritional intake were analyzed. A total of 155 rural-dwelling elderly people (68 males, 87 females) over the ages of 65 participated in this study. The subjects were classified into three groups; the no denture no teeth group, denture user group, and natural teeth group. The dietary intake, biochemical health status, and anthropometry were evaluated. Can-pro 3.0 was used to assess dietary intakes and the SPSS 12.0 program was used for statistical analysis. The results showed that the natural teeth group had better nutritional and dietary intake status than the no denture no teeth group. The dietary assessment showed that there were differences in food intakes among the groups, which depended on their dental health status. In conclusion, dietary management is required for the elderly since each group has a different ability to chew food depending on their dental health status. In addition, the elderly will need different therapeutic diets because of the high prevalence of chronic degenerative diseases.
