The purpose of this study was to compare nutrient intakes and the serum iron status of 74 Food and Nutrition major, and 45 non-major, female students at a university in Incheon. This cross-sectional survey was conducted using a self-administered questionnaire and the data were analyzed by the SPSS 10.0 program. The nutrient intake data collected from three-day dietary recalls were analyzed by the Computer Aided Nutritional Analysis Program. Anthropometric data and hematological indices of iron in the blood were measured. Average heights, weights, body fat and mid-upper arm circumference of Food and Nutrition major and non-major female students were 160.3 cm, 53.5kg, 25.8%, 23.7cm and 159.8cm, 55.5kg, 28.9%, 24.8cm, respectively. There were significant differences in body fat percentage and mid-upper arm circumference between the major and non-major students. In all subjects, daily dietary intakes of nutrients- except protein, vitarrlin B1, vitamin C and phosphorus - were lower than the Korean RDA. In particular, calcium and iron intakes of all subjects were under 60% of the Korean RDA. Values of RBC (red blood cell) count, Hb (hemoglobin), Hct (hematocrit), MCV (mean cell volume), MCH (mean cell hemoglobin), and MCHC (mean corpuscular hemoglobin concentration) of the non-major students were significantly higher compared to those of the major students. The diastolic blood pressure of the major students was negatively correlated with MCV, MCH, TS, and serum iron levels. Triceps skinfold thickness, mid-upper arm circumference and waist-to-hip ratios of the non-major students were negatively correlated with TIBC. Fat intake was positively correlated with RBC, Hb, Hct, and TIBC (total iron binding capacity) in the major students. Vitamin C intake was positively correlated with serum iron in the major students. Carbohydrate intake was positively correlated with Hb, Hct, and MCHC in the non-major students. Niacin and iron intakes were positively correlated with Hb and Hct in the non-major students. Therefore, nutrition education is necessary for female university students to improve nutritional status and to practice optimal nutrition strategies. (Korean J Nutrition 35(9) : 952~961, 2002)

The purpose of this study was to assess the daily steps, physical activities and activity coefficient of policemen (average age: 31.5 ${\pm}$ 5.1 years) who do shift work. Body weight, height and daily steps were measured and one-day activity diary was collected by interviewing with policemen. Average height, body weight, BMI, body fat (%) and muscles (%) of subjects were 173.1 ${\pm}$ 5.2 cm, 73.7 ${\pm}$ 9.7 kg, 24,6 $kg/m^{2}$, 15.5 ${\pm}$ 1.9% and 37.3 ${\pm}$ 5.8%, respectively. The average daily numbers of steps were found to be 9,812 steps/day on day shift duty and 10,888 steps/day on night shift duty and 6,551 steps/day on holiday duty. Hourly step rates on day shift, night shift and holiday came to 1946 steps/hr, 2,130 steps/hr and 1,318 steps/hr, respectively. Activity coefficient (1.75) in night shift of the subjects was the highest and activity coefficient (1.52) in day shift was significantly higher than that (1.31) in holiday (p < 0.05). The rate of expending time for very light activity in holiday (91.5%) was significantly higher than that (70.0%) in night shift. The muscle mass (kg, %) had significantly positive relationship with daily steps in day shift (r = 0.592, r = 0.632) and night shift (r = 0.550, r = 0.503). Triceps skinfold thickness was negatively correlated with daily steps in day shift (r = -0.366, p < 0.05). There were remarkable differences in physical activities and sleeping hours depending on shift works of policemen. In the case of night shift work, sleeping hours was the lowest and activity coefficient was the highest among day shift, night shift and holiday. These results suggest that energy requirements of policemen should be differentiated according to shift work duty.

Nutritional assessment for the elderly can identify health status and morbidity. However, development of Nutritional Risk Index (NRI) remains limited for elderly because of difficulties in understanding physiological mechanism of elderly. This study was performed to analyze and develop Nutritional Risk Index for Korean elderly Women (Geriatric Nutritional Risk Index, GNRI). Based on literature review, factors for NRI were identified and indices were assessed by a cross-sectional survey. The survey involved Korean elderly women (${\geq}$60, n = 94) in Gwangju area, and sociodemographics, lifestyle characteristics, health conditions, dietary intakes based on 24h- recall, anthropometric measures (wt, ht, BMI, waist, hip, WHR, body protein, body fat, abdominal fat, and triceps skinfold thickness), and clinical biochemistry parameters (systolic blood pressure, diastolic blood pressure, cholesterol, HDL-cholesterol, triglyceride, total protein, albumin, prealbumin, hemoglobin, hematocrit, fasting blood glucose, HbAlc, ferritin, Zn, Ca, Na, K, Vit E, Vit $B_{12}$, folate, C-reactive protein) were examined relation to nutritional risk index. Based on literature review and data analyses, three NRIs were categorized (NRI I, NRI II, NRI III) and used for further analysis. NRI I was related to having metabolic syndrome, NRI II was related to serum albumin and body weight, and NRI III was related to food habit and health concerns. Abdominal fat (%) of elderly was correlated with each NRIs. NRI II was correlated with nutritional deficiency and higher tendency of inflammatory response, and NRI III was correlated with nutritional status which tend to be lower on aging (protein, folate, Vit $B_{12}$). NRI can serve as a useful tools in assessing health risk and nutritional status. Some modification of items in NRI and validity study are need to apply to Korean elderly.

The prognosis of maintenance hemodialysis (HD) patients is closely related to their nutritional status. It is important to develop and use of a reliable, useful and easy method of nutritional assessment scale for evaluation of nutritional status and progression of the patients. This study was initiated to evaluate the clinical usefulness of Instant Nutritional Assessment Scale(INAS) by cross-sectional and longitudinal studies. One hundred HD patients entered a continuing nutritional study and followed for 1 year. The results were as follow ; 1. 24% of patients was normal to mild, 43% was moderate and 33% was severe deficit of nutritional status. 2. The mean INAS score of the patients was 8.00(S. D.=2.83), and there didn't reveal any differences in INAS score by general characteristics. The mean transferrin score was 1.98, whih was the highest of 5 nutirtional parameters of INAS. Only 7 patients had within nomal range of transferrin concentration. 3. Within one year since this study was initiated, 10 patients died. Six of them were with severe deficit and one of them was normal to mild deficit groups. The death rate in severe deficit group was higher than that of normal to mild deficit group (P=.0640). 4. Occurrence of acute complication during HD in severe deficit guoup was higher than that of normal to mild deficit group(P=.001). 5. The number of consultation to the doctor and hospital admission in severe deficit group was higher than that of normal to mild deficit group(P=.0001). 6. INAS score was significantly correlated with occurrence of acute complications during HD and the number of consultation to the doctor. In conclusion, INAS based on the levels of body mass index, midarm circumference, triceps skinfold thickness, transferrin concentration and total lymphocyte count seems to be a reliable predictive nutritional index for prognosis. So nurses are encouraged to adopt INAS in care of the chronically illed patients. Recommendations for further research was suggested.

This study was conducted to evaluate the nutritional status and diabetes management of diabetic patients in the Health Center. General characteristics, food habits, food intakes and the knowledge about diet therapy were investigated from ninety one diabetes subjects. Anthropometric assessment such as weight, hight, triceps skinfold thickness, and biochemical measurement of fasting blood glucose(FBG), post prandial 2 hours blood glucose(PP2), and hemoglobin A1c(HbA1c) were obtained form the subjects. The results were summarized as following : 1. The average of age was 60.9 years old and 83.5% of subjects was illiterate and primary school graduated. 2. Relative Body Weight(RBW) and % body muscle were 96.18${\pm}$13.6 and 33.56${\pm}$7.01%, respectively. Obese subjects whose body weight exceeded 120% of the ideal values were 3.3%. 3. The 86.8% of subjects were managed by oral hyperglycemic agents. 4. The mean of FBG, PP2, HbA1c were 140.75${\pm}$44.43mg/㎗, 7.60${\pm}$1.88%, respectively. 5. The mean daily intake of calorie was 1407㎉, and 73.6% of subjects lower caloric intake than prescribed calorie. when the degree of dietary compliance was expressed as Tunbridge score, 18.7% of total subjects was grouped as satisfactory, where as 20.9% and 60.4% could be considered as tolerable and hopeless, respectively. The nutrients intake were lower than RDA except for Vitamin A and Vitamin C and the ratio of carbohydrate : protein : fat was 72 : 14 : 14. 6. The mean score of knowledge test about diet therapy was 3.52${\pm}$2.19 out of possible 14.00 points. The above results suggested that the most of diabetic patient showed the poor nutritional status and they faced the lack of knowledge about diabetes management.

The purpose of this survey was to investigate the prevalence of obesity, eating habits and life styles of children. This survey was carried out anthropometry and questionnaires in 180 male and 141 female students of fifth-grade at Dongmak elementary school. The results are summarized as follows : 1)18.2% of the male and 19.3% of female students were obese. Underweight group was 10.5% of the male and 15.0% of the female students. 2) Average height of male and female students were 142.0㎝, 144.0㎝ and weight of those were 35.8㎏ and 37.1㎏ respectively. The height and skinfold thickness of the triceps in female students were significantly higher than those of male students and body fat content in female students was significantly lower than that of male students. There was no difference in BMI, RW and RI between male and female students. The average BMI, RW, RI were 17.7, 25.4, 124.0, respectively. 3) The student's height was positively related to parent's height and moth's weight. There were significantly positive correlation between mother's and subject's weight. BMI, RW and RI were positively related to parent's BMI. 4) 78.3% of male and 51.8% of female students had prejudice for special food, and 45.5% of male and 34.5% of female students had an overeating habit. Male students had significanthy higher rate than female in both cases. Average eating time per meal was 18.9 minutes for male and 21.0 minutes for female students. Experience for taking nutrient supplement in male student was more than that in female. Obese group had prejudice for special food, overeating habit and rapid eating rate more than any other groups. The prevalence of obesity among the children is gradually increasing. Therefore, in order to prevent progress into adulthood obesity, nutrition education including the right perception for obesity and eating behavior modification was needed.

To assess the nutritional and health status of the elderly, anthropometric measurements and blood test for analyzing biochemical indices were carried out from August to September in 1996. Data on the incidence of a specific disease and clinical symptoms were also collected by interviews with a questionnaire. Among the total of 169 free-living elderly interviewed(91 men, 78 women), 86 elderly(57 men, 29 women) participated in the anthropometric measurements, and 73 elderly(52 men, 21 women) in blood tests. Average heights and weights were much lower than the standards established in the Korean Recommended Dietary Allowances. While average triceps skinfold thickness of men and women were above the 50 percentile of the reference data, mid-arm muscle circumferences were lower than the 50 percentile. Prevalences of anemia, assessed by hemoglobin using WHO definition, were 38.5% for men and 33.3% for women. Blood levels of total protein and albumin were above the normal limit for all participants. Mean blood cholesterol levels of men and women were 163.9mg/dl and 185.8mg/dl, and triglyceride levels were 138.2mg/dl and 161.9mg/dl, respectively. Women older than 75 years generally had high levels of BMI, total cholesterol and triglyceride. Health status assessed by clinical symptoms generally showed no significant difference by age, and their smoking, and drinking habits. Males and the elderly who exercised regularly had better health status. It was suggested that exercise was a good way to improve health status. (Korean J Community Nutrition 2(4) : 568-577, 1997)

This study was carried out to collect information to establish a framework for meal management and nutritional service for prevention of chronic degenerative disease in the industrial workers. We investigated the health concerned life-style, nutrient intakes, anthropometry and biochemical parameters in the male workers in Korea by work condition. Anthropometric parameters of height, weight, waist, hip and triceps skinfold thickness were measured and biochemical parameters including Urine pH, hemoglobin, blood glucose, total cholesterol, GOT, GPT, $\gamma$-GPT and blood pressure were determined for 101 subjects(50 office workers : 33.9yr, 51 laborers : 34.4yr). To assess the nutrient intakes and diet quality of workers, dietary intake was measured by one day 24-hour recall method. Result of anthropometric parameters of height(p<0.01), weight(p<0.05), hip(p<0.05), TSF(p<0.01) were significantly higher in office workers than in laborers. Biochemical parameters were not significantly difference in both of them. Average daily nutrient intakes of both groups was higher than the Korean RDA and report on 2001 National Health & Nutrition Survey. The calcium(p<0.01), iron(p<0.05), vitamin A(p<0.01), vitamin B1(p<0.01) and niacin(p<0.05) intakes in laborers were significantly higher than in office workers. Nutrition adequacy ratio(NAR), mean adequacy ratio(MAR) and index of nutritional quality(INQ) of laborers were higher than those of office workers. This results indicated that the onset possibility of chronic degenerative disease appeared higher in office workers. Therefore, meal menagement and nutritional service for prevention of chronic degenerative disease of industrial works needs to be more variant guidelines.

The purpose of this study was to develop cardiovascular health related percent body-fat standards that may be applied to epidemiologic investigations of the prevalence and incidence of obesity in adolescents, pediatric health screenings, and youth fitness tests. The subjects included 102 males and 80 females aged 19～22years. All subject were Honam University Students Total body fat was derived from body density which was estimated from age and the triceps and subscapular skinfold thickness measured with Lang calipers to the nearst l.0mm. Serum total cholesterol and lipoprotein cholesterol fraction(HDL-CLDL-C) were measured from blood obtained from fore arm vein after blood pressure measurement. In analyses to determine critical fat levels associated with elevated CDD(Chronic Degenerative Disease) risk factors;male and female were grouped by level of percent fat as follows: male, 〈 10%, 10-14.9%, 15-19.9%, 20-24.9%, and $\geq$ 25%;female, 〈 20%, 20-24.9%, 25-29.9%, 30-34.9%, and $\geq$ 35%. As the results of the data, the conclusions were as follows: 1. A dose respones effect was observed between blood pressure and percent body fat in males and females; in contrast, total cholesterol and lipoprotein ratios were relatively independant of percent fat among the lower four fatness group in males and the lower three fatness groups in females. 2. The percentage of subjects in the uppermost quintile for S-Bp, D-Bp, TC, LDL/H was significantly(P〈.05) greater than expected by change alone(20%) in males with $\geq$ 25% fat and in females with $\geq$ 30% fat females with $\geq$35% had even greater representation in the uppermost quintile of all CDD risk factors compared to females with 30-34.9% fat.

This study was undertaken to investigate the dietary factors related to the incidence of stomach and colon cancers in Korean. The subjects were 139 stomach and 52 colon cancer patients recruited from 3 general hospitals in Seoul. Food intake, anthropometric measurement, and blood compositions were studied through personal interview and using medical records. Body weight, body mass index, triceps skinfold thickness, body muscle mass of the subjects were lower than reference values. The body weight was reduced after the onset of the illness, which suggests body waste due to the cancers. The patients showed the lower valuies of hemoglobin and hematocrit. Serum protein and calcium were at lower limit of the normal range. Therefore the untritional status assessed by anthropometry and blood composition should be said to be marginal. The average intake of most of the nutrients except Ca of the subjects met the RDA, but the range was wide and the nutrient intake of large proportion of the subjects feel below 75% of RDA. The food intake of egg, milk, legumes, and fruts were lower than national average, on the other hand the subjects had higher intake of meat, vegetables, and fats. The subjects drank and smoked heavily, stomach cancers being more severs. From this results, dietary risk factors for the stomach and colon cancers in Korean did not agree with the reports of western societies. Even though the intakes of meat and animal food of colon cancer patients can not be classified as high, it was higher than stomach cancer and national average. Therefore it could be concluded that with increasing consumption of animal food, the incidence of colon cancer would be increased in Korea.
