Since 1982, female agricultural workers are populous than male in Korea. Previous study was suggested that female workers are more sensitive to the agricultural medicine poisoning than male. This study was conducted with the aim of evaluating the impact on plasma components and nutrient intakes in female agricultural workers by the use of pesticides. Data were obtained from 44 females residing in Wonjoo, Kangwon-do area. Analysis for the general characteristics, nutrient intakes, and plasma components of the subjects were performed by physical examination, 24-hour recall method and venous blood sampling. They were divided into 3 groups according to the degree of the pesticide use: 8 in none(Non-expose group), 14 in low(<4/yr)(Low-expose group), and 22 in high$({\geq}4/yr)$(High-expose group). The results are summarized as follows. Serum glucose, SGOT, SGPT, triglyceride, HDL-cholesterol did not correlated with pesticide use and were not different among the groups. But serum total cholesterol was higher in pesticide use group. With increasing the number of pesticide use times, leukocyte count was tended to increased. Eighty two percent of the subjects were hemoglobin less than or equal to 12g/dl. Hematocrit, MCV, MCH, MCHC, serum Fe, Serum ferritin belonged to normal range and did not correlated with pesticide use. Intake of energy, Fe, vitamin $B_2$ were lower than RDA. Fe, K, and vitamin A intake were higher in don't use group than the other groups. There are not many differences according to using the pesticide in anthropometric measurements, nutrient intakes, and blood components, except for serum total cholesterol level and some nutrients intake. But these results suggest the need the systemic researches about the effects the pesticide using on nutritional status in Korean agricultural workers.

According to economical status, under-nutrition and over-nutrition coexist in preschool children in Korea. Subjects consumed more than RDA in most nutrients, and children in of the upper income class tended to have more nutrients than those of the low income class. Especially in case of energy, protein, fat, vitamin $B_2$, and P there were significant differences among the different classes. The mean calorie compositions of carbohydrates, protein and fat were $57{\sim}59:\;16{\sim}17:\;26{\sim}27$ and fat calorie percentage was higher than quantity recommended for Korean adults. Energy, protein, Fe, vitamin A, $B_1$ and C intakes were taken mostly from plant food sources. In the upper income class group, intakes of protein and vitamin $B_2$ from animal food sources were higher than in any other income classes. Intakes of iron, vitamin A, $B_1$ and C were largely provided by plant food group. Especially 44-45% of vitamin A were taken from vegetable and fruits group, which indicated that about 50% of vitamin A intake was the form of ${\beta}-carotene$. Also compared with other groups, in the upper income class group, the intakes of energy, protein, Ca, p, vitamin $B_1$ and vitamin $B_2$ from cereal and potatoes were significantly lower, and those of Ca and P from milks and meats, fishes & eggs were significantly higher(p<0.05). The mean fat intake in all subjects was $38{\sim}43g/day$. Regardless of income class, oleic acid($6.6{\sim}8.4g$) and linoleic acid($6.7{\sim}8.1g$) were the most abundant fatty acids contained in the diet. The upper class group consumed significantly more total saturated fatty acids and total monounsaturated fatty acids(p<0.05). In polyunsaturated fatty acids, there were no differences between 3 different income classes, but intakes of total ${\omega}6$ fatty acids in the upper class tended to be higher and those of total o3 fatty acids in low class tended to be higher. Therefore, ${\omega}6/{\omega}3$ tended to be higher in the upper class group. Regardless of income classes, P/M/S and ${\omega}6/{\omega}3$ ratios in all subjects were $0.9{\sim}l.3/1.0{\sim}1.1/1.0$ and $5.2{\sim}7.4/1.0$, respectively and were in a desirable range. Cholesterol intake of subject was 184-218 mg/day, which was comparable to the value of Korean adult intake.

To assess riboflavin status by dietary intake and urinary excretion of preschool children in Busan and to evaluate the relationship of intakes of food and nutrient with urinary riboflavin excretion, riboflavin food frequencies of 40 common foods affecting intakes of riboflavin by food fequency method, nutrient intake by 24hr recall and 24hr urinary riboflavin excretion were measured with 97 preschool children. The mean riboflavin intake was 0.90 mg and above RDA. Dairy group was the primary source of riboflavin intake and provided 44.8% of the total daily riboflavin intake. The mean urinary riboflavin excretion and riboflavin excretion per gram of creatinine were 395.21$\mu\textrm{g}$ and 2110.41$\mu\textrm{g}$ respectively, The mean riboflavin intake (p<0.01, p<0.01), riboflavin density (p <0.001, p<0.001) and urinary riboflavin excretion per gram of creatinine (p<0.05, p<0.05) were significantly low with the two patterns of food group intake where dairy group was omitted (GMVFDS = 111101, consuming no dairy group and GMVFDS=l11001, consuming no fruit and dairy groups). On the basis of urinary riboflavin excretion per gram of creatinine, 14.3% of subjects in the group aged 1 to 3 and 18.2% of subjects in the group aged 4 to 6 were at risk of deficiency respectively. The urinary riboflavin excretion per gram of creatinine showed positive significant correlations with usual intakes of riboflavin from food groups of dairy (p<0.05), meat (p<0.05) and animal (p<0.05). So nutritional education is needed in order to consume dairy food group daily and to increase usual intake of animal food group including meat.(Korean J Nutrition 35(9) : 970~981, 2002)

This study was performed to evaluate the quality of nutrient intakes of the hemodialysis patients (26 men and 23 women) according to the socioeconomic status by 3-day dietary recall in Daejeon city and Chungnam area, Korea. Mean age of the subjects was 50.7 yrs and BMI was 22.0 $\pm$ 0.4 kg/$m^2$. Education level was divided into two groups ($\leq$ 9 years： LE group, 9 years： HE group), and monthly family income level was divided into three groups (< 500,000 won: LI group, 500,000-1,499,999 won: MI group, $\geq$ 1,500,000 won : HI group). The data were analyzed by Student t-test and Oneway ANOVA using SPSS 9.0 version at p < 0.05 level. Intakes of energy, carbohydrates, cholesterol, potassium, thiamin and riboflavin were significantly higher in HE group than in LE group (p < 0.05). Intakes of all the nutrients except protein and phosphorus were less than Korean RDA, and INQs (Index of Nutritional Quality) of most nutrients were lower than 1.0 but cholesterol, phosphorus. thiamin and niacin being over 1.0 in HE group. MAR (Mean adequacy ratio) of all the nutrients (e.g., energy, protein, calcium, phosphorus, iron, vitamin A, vitamin C, thiamin, riboflavin and niacin) was significantly higher in HE group (0.61 $\pm$ 0.04) than in LE group (0.48 $\pm$ 0.03) at p = 0.036. Intakes of energy, protein (total, animal and plant), fat, cholesterol, potassium, calcium, phosphorus, iron, vitamin A, thiamin and riboflavin were also significantly higher in HI group than in LI and MI group (p < 0.05). Daily intakes of most nutrients were less than Korean RDA except protein ed phosphorus in HI poop, and INQs of thiamin, niacin and phosphorus were higher than 1.0, while those of calcium, iron, vitamin A and riboflavin were lower than 1.0. MAR of energy and 9 nutrients was significantly higher in HI group (0.70 $\pm$ 0.04) than in LI group (0. 56 0.04) and MI poop (0.47 $\pm$ 0.03) at p = 0.000. In conclusion, quality of nutrient intakes, especially energy and protein, was significantly influenced by socioeconomic status such as education and monthly income (p < 0.05). This result suggests that it would be very helpful to develop nutritional education programs considering hemodialysis patients' education levels, and to improve public supports (e.g., medical insurance system, low-rate lease system of dialysis equipments, etc.) focusing on the patients' family income levels f3r their better nutrition and health.

The present survey was designed to investigate correlations among blood pressure, nutritional intakes, and various environmental factors in Korean adult males, and to observe the difference in dietary intakes between hypertensive patients and normotensive subjects. Two hundred forty-three adult men from Seoul and rural areas were interviewed about their food intakes, dietary patterns, food habits, and general environmental factors from December 20, 1982 to February 15, 1983. Their dietary intakes were surveyed by means of 24-hour recall diet method. Dietary score card was used in order to evaluate the quality of routine diet of the subject. Variables of environmental factors and factors related to hypertension were expressed as percentage, and the differences in nutrient intake and food score of each sub-group were examined by means of t-test. Correlation of all the variables were analyzed by Pearsons Correlation Coefficient. The results obtained are summarized as follows: 1. 38% of the subjects were between the ages of 40~49, and about one-half of the subjects were middle or high school graduates. 28% of the subjects earned 210, 000~350, 000 Won per month, and income distribution was almost identical to that of the urban population of Korea. 2. There was more overweight or obese found in the hypertensive patients than in the normotensive subjects. About 40% of the hypertensive patients reported a family history of hypertension, and their knowledge about hypertension was rather poor, but slightly better than the normotensive subjects. The patient group had less adherence to smoking and alcohol compared with the normotensive subjects, but no difference was observed in coffee drinking. The mean value of the blood pressure for the normotensive subjects was 127/86mmHg and 175/109mmHg for the hypertensive group. 3. Nutrient intake for the hypertensive group was lower for most of nutrients than in the healthy group. Hypertensive patients on diet therapy consumed less calories and carbohydrates compared with those who do not follow diet therapy. 4. There was no difference intake of these food groups between patients and the healthy group. Food score was strongly related to consumption of animal protein, saturated fats, Calcium, Iron, Vitamin A, Riboflavin, and Vitamin C, which are prone to be deficient in the typical Korean diet. 5. Blood pressure had a strong positive correlation with age, body weight, and socioeconomic level. In addition, monthly income was positively related with age and education level. 6. Three was a positive relationship between blood pressure and consumption of vegetable protein, and a negative relationship with consumption of Calories, Carbohydrates, Calcium, Iron, Vitamin A, Vitamin B1, Niacin, and Vitamin C. Animal protein intake increased as income and education levels increased, but this tendency was opposite for carbohydrates. In summary, nutritional intakes are strongly correlated with various environmental factors and the level of blood pressure. There was no difference between normotensive and hypertensive subjects with respect to the quality of food consumed except restricting energy and carbohydrate in the patient group.

This study examined the effectiveness of two commonly used dietary assessment methods (the 24-hour recall and the food frequency questionnaire) in the epidemiological investigations of health-related habits and degenerative diseases. This cross sectional project in the Seoul area was conducted for the purpose of establishing cohort subjects and collecting reliable nutrient intake data for a further large-scale cross sectional study. The subjects were 91 volunteers from the Seoul area with a mean age of 53.5 \pm 9.6 for the males and 52.2 \pm 8.9 for the females. The subjects had a relatively high educational background, were from high socioeconomic levels, and were greatly concerned about healthrelated life styles. There was a significantly negative correlation between their smoking and their nutrient intake. Their drinking habits, their self-estimated health status and their concern or stress about being healthy did not have any influence on their nutrient intakes. Skipping meals was the most undesirable dietary habit influencing their nutrient intakes, and the next was their irregularity of eating meals. The subjects who liked legumes and fish had higher intakes of iron and niacin and those who liked milk and dairy products had higher intakes of calcium, vitamin \B_2 and fat. The subjects who considered themselves not to be healthy consumed higher amounts of fish and shell-fish, and those who considered themselves to be healthy consumed higher amounts of vegetables. The smokers consumed less fruits than non-smokers, but there was no correlation between their drinking and consumption of the food groups. There was no correlation between their food consumption frequency and their skipping meals or meal irregularity. There were positive correlations between their food likes and food consumption frequency for foods such as meat, milk and dairy products, seaweeds and fruits. Therefore, their smoking, skipping meals and meal irregularity appeared to greatly influence their nutrient intakes. Significant correlations were found between their health-related habits and their food group preferences and food frequencies. This implies that simple surveying methods using criteria such as smoking, skipping meals and meal irregularity, food group preferences and eating frequencies can be used as useful tools in the assessment of nutritional statuses.

BACKGROUND/OBJECTIVES: The elderly are reported to have a high prevalence of nutritional anemia when they have lower intakes of nutrients or chronic diseases. This study was conducted to compare nutritional status according to nutritional anemia and to determine associations between nutritional anemia and chronic diseases in Korean elderly. SUBJECTS/METHODS: This study utilized data on 3,258 elderly aged ${\geq}65$ years gathered during the $6^{th}$ Korea National Health and Nutrition Examination Survey 2013-2015. Subjects were divided into nutritional anemia (NA) group (n = 415) and non-NA group (n = 2,843) by hemoglobin concentration. Nutrient intakes were assessed using dietary intake data obtained using the 24-hour recall method. The odds ratios (ORs) for nutritional anemia by chronic diseases were determined. Statistical analysis was performed using SPSS Ver. 23.0. RESULTS: Of 3,258 subjects, 12.7% had nutritional anemia. Intakes of potatoes, pulses, and mushrooms by males and potatoes, fruits, meats, eggs, and seafood by females were significantly lower in NA group than in non-NA group. The proportion of the subjects whose intakes of protein, vitamin A, vitamin $B_1$, vitamin $B_2$, niacin, and iron less than estimated average requirement (EAR) were significantly higher in NA group compared to non-NA group. After adjusting for age, the number of family members, energy intake, and alcohol drinking, ORs for nutritional anemia in the subjects with diabetes and myocardial infarction or angina pectoris were significantly higher by 1.74 times and 1.59 times as compared to the subjects without those diseases, respectively. However, ORs for nutritional anemia in the subjects with obesity, abdominal obesity, and hypertriglyceridemia were significantly lower by 0.64 times, 0.60 times, and 0.59 times as compared to the subjects without those diseases, respectively. CONCLUSIONS: The results of this study suggested that nutritional management should be done to enable the Korean elderly to consume foods with high hematopoietic nutrients density to prevent nutritional anemia. Korean elderly need to make regular efforts to check for nutritional anemia.

The purpose of this study was to evaluate nutrients intakes, glycemic index (GI), glycemic load (GL) according to obesity index in elementary school students. The study subjects included 229 elementary school students (boys=108, girls=121) who were divided into 3 groups consisting of an underweight group (obesity index<-10%, n=58), a normal weight group (10%${\leq}$ obesity index<10%, n=130) and an overweight group (obesity index${\geq}$10%, n=41) by their obesity index. The nutrient and food intakes data obtained by a 3-day food record were analyzed. Daily dietary GI and GL values were calculated from the 3-day food record. The average age of the subjects was 11.9 years. The mean daily energy intake was 2,186.8 kcal in the underweight group, 2,123.5 kcal in the normal weight group, and 2,174.2 kcal in the overweight group. The intakes of calcium and animal calcium per 1,000 kcal in the overweight group were significantly lower than in the underweight and normal weight groups (p<0.01, p<0.05), and fruit, egg and milk intakes in the overweight group were lower than those in the underweight group (p<0.05, p<0.05, p<0.05). The mean daily dietary GI of the underweight, normal weight, and overweight groups were 67.7, 68.4 and 69.5, respectively (p<0.05). The mean daily dietary GL of the underweight, normal weight, and overweight groups were 212.8, 208.1 and 213.3, respectively. The major food source of dietary GI and GL in the three groups was rice. Other major food sources of dietary GI were croquettes, hand-rolled noddle soups, instant noddles, milk, and rice cake. Dietary GI was not significantly correlated with weight, obesity or body mass index, when adjusted for energy, carbohydrate, and dietary fiber. However, GL adjusted to energy, carbohydrate and dietary fiber tended to correlate with obesity index (r=0.126, p=0.059). These results suggest that dietary GI and GL have possibility affecting obesity-related indicators in elementary school students.

The purpose of this study was to investigate the difference of general characteristics, menopause status, dietary patterns and nutrient intakes between women aged from 30 to 65 years old with a hypercholesterolemia group and normocholesterolemia group. The subjects were classified as belonging to the hypercholesterolemia group or normocholesterolemia group barred on The Guidelines for Korean Hyperlipidemia. Dietary intakes of fatty acids were measured by means of a 24-hr recall method with food models and measuring tools. We analyzed both data sets together using analysis of variance chi-square test and student's t-test(SPSS for WINDOWS, version 7.5). Significance was defied as a p value < 0.05. The results obtained are summarized as follows. Mean age and BMI of the hypercholesteroemia group were significantly higher than those of the normocholesterolemia group. Intakes of cereal, vegetables, mushrooms and sea food in the normocholesterolemia group were significantly higher than those in the hypercholesterolemia group. Most of the nutrient intakes were not significantly different between the normocholesterolemia group and the hypercholesterolemia group. However, vitamin E intake of the normocholesterolemia group was significantly higher than that of the hypercholesterolemia group. There was a significant negative correlation between vitamin E intake and serum TC(r = -.363, p < 0.001) and LDL-C(r = -.359, p < 0.001). In addition, Serum TG had significantly correlation with carbohydrate(r = 0.137, p < 0.001) and vitamin E intake(r = -0.134, p < 0.001). Therefore, women who suffered from hypercholesterolemia were recommended to control body weight, and to consume foods containing high vitamin E and foods containing high dietary fiber such as vegetables, mushrooms, and sea food.

The purpose of this study is to investigate dietary pattern and health status related to food habit and degree of fatigue of evening college students. A sample of 476 evening college students in Chonbuk area were surveyed by questionaire examining their food habit, nutrient intakes, degree of fatigue and cornell Medical Index(CMI). In this study, the male and female students were classified into two groups, respectively, the first group is not having jobs and the second is having jobs. The results were summerized as follows: 1. Evaluation status of food habit score indicated that the subjects were included in Fair and Poor group generally. Food habit score of female was significantly higher than score of male. For female students, food habit score of job group was significantly higher than score of non-job group(p<0.05). 2. Average intakes of calorie and protein were 1869.1 kcal and 68.3 g in male and 1612.4 kcal and 58.3 g in female. Other nutrients, such as vitamin $B_1$(1.1 mg), vitamin $B_2$(1.2 mg) and ascorbic acid(41.0 mg) in male, iron(13.5 mg), vitamin $B_2$(1.1 mg) and ascorbic acid(46.5 mg) in female were lower than the korean RDA. 3. The means of degree of physical, mental, neurosensory and CMI scores were 3.1, 1.9, 1.5 and 4.7 in male and 4.0, 2.4, 2.4 and 7.1 in female, respectively. For female students, though significancy was found between job group and non-job group in physical, neurosensory fatigue and CMI score(p<0.05, 0.01), but there were not significant differences in these score for male students. 4. There were significant positive correlation between three types of fatigue and CMI, whereas score of food habit was negative correlation for degree of physical, mental fatigue and CMI. The intakes of protein and vitamin $B_1$ were significantly related to the mental, neurosensory fatigue and CMI.
