This study was aimed at examining the pattern of dietary fat intake of 120 university female students living in Kongju city in order to provide baseic data for establishing the dietary grideline of desirable fat intake. The subjects were divided into three groups according to living arrangenment ; family home(FH), or dormitory(DM), or self-boarding house(SB). Fat consumption of subjects was surveyed by two-day food records, and profiles of fatty acid and cholesterol taken were calculated based upon the data reported their contents of foods. The result was that mean daily fat intake was 42$\pm$2g for FH, 48$\pm$4g for DM and 41$\pm$3g for SB. The calorie intake by fat was 20.8, 21.5, and 20.4% respectively. The ratio of P/M/S was 1.3/1.7/1 for FH, 1.3/1.6/1 for DM and 1, .5/1.5/1 for SB. And the ratio of n-6/n-3 fatty acid was 5.2/1 for FH, 8.3/1 for DM and 7.2/1 for SB. Daily cholesterol intake was 208$\pm$20mg for FH, 223$\pm$29mg for DM and 251$\pm$27mg for SB. In addition, intake of n-3 fatty acid was 1.2$\pm$0.2g for FH, 0.9$\pm$0.1g for DM and 1.2$\pm$0.2g for DB. Considering the food source of fatty acids, saturated fatty acid and monounsaturated fatty acid were taken primarily from animal foods, especially milk and milk products, and n-6 polyunsaturated fatty acid was taken from vegetable oils and fats. As a major source of n-3 fatty acid, linolenic acid was obtained through vegetable oils and fats, and eicosapentaenoic acid and docosahexaenoic acid were provided by fishes and their products. There patterns of fatty acid intakes did not differ according to living arrangement. The above results showed that intakes of fat and cholesterol, and ratios of P/M/S and n-6/n-3 fatty acid were overall desirable in all groups. However, intake of n-3 fatty acid was low in all groups. Therefore, consumption of perilla oil, legumes and fishes as a source of n-3 fatty acid should be increased by substituting other food source which provide fats and oils because calorie intake by fat was enough in these subject.

This study was conducted to investigate dietary factors, bone status, and bone loss in postmenopausal women in rural areas. A total of 189 women participated in the follow-up study after two years. Radius, Tibia, and Phalanx SOS (Speed of Sound) was measured on two occasions 2 years apart by ultra-sonic-metry, and % body fat was measured by bioelectrical impedance analysis at the baseline and after 2years. Dietary intake data were collected 4 times at different season by 24-hour recall method, and then calculated as average. Bone density of radius decreased by 4.2% during the two year period. When the subjects were divided into three groups, by bone decline level during two years, the lowest bone loss group had higher potassium and vegetable intake than other groups. Age and calcium intakes showed significant correlation with bone decline rate at tibia. In multiple regressions, the baseline SOS, vitamin A, vegetables and eggs intakes were found to be significant factors for tibia bone decline. In conclusion, dietary factors, such as higher vegetable intake, seem to affect the changes in bone mineral density in more favorable way. Therefore, efforts are needed to enhance the access to nutritional care for rural elderly postmenopausal women.
This study was conducted to determine whether dietary factors could be related with serum adiponectin concentrations in 243, year-three female university students living in Seoul. The mean of body mass index (BMI) and adiponectin levels of all subjects were $20.17kg/m^2$ and $11.07{\mu}g/ml$, respectively. When the subjects were divided into 3 groups based on BMI (underweight: < 18.5, normal: $18.5{\leq}<23$, overweight and obesity: ${\geq}23$), serum adiponectin levels in underweight group was significantly higher than that in 'normal' or 'overweight and 'obesity' groups. Also when the subjects were divided into two groups by mean adequacy ratio (MAR), serum adiponectin concentration of the high MAR group (MAR > 75) was slightly higher than that the low MAR group ($MAR{\leq}75$). Serum adiponectin levels showed a negative correlation with body weight (p < 0.01) or BMI (p < 0.001) and a positive correlation with intakes of of animal or total protein (please clarify) or vegetable protein.Among the dietary behaviors, serum adiponectin levels of females who answered 'yes' to the question about 'eating breakfast' was significantly higher than that of those who answered 'sometimes' or 'No' (p < 0.05) and serum adiponectin levels were higher among those who reported higher fruit intakes. Overall, our results suggested that healthy lifestyle including acceptable BMI, eating breakfast and higher fruit consumption might play an important role in the prevention of obesity and enhancement of blood adiponectin levels.
Interactive effects among eating behavior, obesity and serum lipid levels were studied in 117, 4~12 year old children residing suburban Seoul. Fasting blood samples are obtained and analyzed for serum triglycerides (TG), total cholesterol(TC), high density lipoprotein-cholesterol(HDL-C) and hematochrit. Obesity was determined by weight for length index(WLI)and the information on eating behavior including food habits and dietary intakes was obtained by questionaire using food record method for 2-consecutive days. Over 40% of children was classified overweight or obese by WIL and children's physical parameters were closely related to those of parents implying genetic influence on obesity. Although it did not reach the statistical significance, there was a tendency of higher TG, TC and low density lipoprotein-cholesterol(LDL-C)levels among girls compared to boys. Blood lipid levels of obese children were similar to those of other groups except TG, which was significantly higher(p<0.05) in obese group. Nutrient intakes seemed adequate in all subjects except iron, calcium and total calorie which were lower than RDAs. Lacking significant relationship between individual nutrient intake and obesity, there was significant correlation between food intake and blood lipid level especially in 10-12 year old group. Vegetable intake was negatively related to TG, LPH(LDL-C/HDL-C) and atherogenic index(AI), and positively to HDL-C. Skipping breakfast and frequent eating out appeared to cause imbalances in nutrient intake. These findings clearly revealed the influence of eating behavior on childhood obesity along with blood lipid profile. To ensure the proper growth and health of these children, devising method and developing media for nutrition education suited to our society should be accomplished first. With well-planned nutrition surveys and thorough intention, childhool obesity could be prevented from progress into adulthood obesity.

This study was conducted to estimate the contents of trace metals in vegetable which were produced in Korea. The levels of trace metals determined using a mercury analyzer, and ICP (inductively coupled plasma spectrometer) and an AAS (atomic absorption spectrophotometer) after wet digestion. The values of trace metals [minimum~maximum (mean), mg/kg] in vegetables were a follows ; Hg : 0.0001~0.019 (0.002), Pb : 0.001~0.28 (0.02), Cd : 0.001~0.078 (0.016), As : 0.001~0.06 (0.02), Cu : 0.06~24.81 (0.77), Mn : 0.17~15.12 (2.32), Zn : 0.13~28.70 (2.51). These results showed that metal contents in vegetables on domestic markets were similar to those reported in other countries. The weekly average intakes of lead, cadmium and mercury from vegetables take 2~7% of PTWI (Provisional Tolerable Weekly Intakes) that the FAO/WHO Joint Food Additive and Contaminants Committee had set to evaluate their safeties.
Picky eating behavior is a significant factor in causing unhealthy eating and disturbing the growth of children. This study examined picky eating behaviors and food intake of 112 preschoolers aged 3~5 year, picky eaters (n=41) and non-picky eaters (n=71), living in Dobong-gu, Seoul metropolitan area, South Korea. Picky eating questionnaires and three consecutive 24-hour dietary recalls were collected from their caregivers. The difference between the two groups was verified using a Chi-square test or t-test and Pearson's correlation. Compared to the non-picky eaters, fussiness, satiety responsiveness, and refusal of food variety were significantly higher in picky eaters (P<0.001). Compared to the non-picky eaters, an assessnent of the preschooler's behavior and the caregivers' perception were positively correlated in picky eaters (r=0.749, P<0.001). The intakes of shellfish (P<0.05), vegetables (P<0.001), fiber, vitamin E (P<0.01), vitamin A, and folate (P<0.05) were significantly lower in picky eaters than the non-picky eaters. The major food sources of vitamin A and folate were vegetables, of which grains were the source of fiber, fats and oils were the source of Vitamin E, and root vegetables were source of vegetables in both picky and non-picky eaters. In conclusion, picky eating behaviors are related to different fussiness and slowness in eating. Therefore, it is suggested to increase the amount of meal and vegetable intake in picky eaters.
In this survey, we investigated the way of thinking about meal management of housewives including the sincerity to meal preparation, the eating practices and cronic degenerative diseases related dietary behaviors, and studied the effects of above factors on the real food intakes. We also investigated the trends of health-foods and nutrient supplements usage. The results obtained from 506 housewives in Seoul were summarized as follows. Although our subjects prepared their meals habitually without special concern, they did not prefer the use of convenient foods. The food prefrence of housewivess who had more child and refered higher life status was similar with other family members. The dietary attitudes were good in large family, the higher income and the more child group. The highly educated group skipped breakfast more frequently. The mealmanagers with better education career and good living status considered for the restriction of salty foods, sweet foods, animal fats and pungent foods, and for the nutritionally balanced diet. The high income group showed great concerns about weight gain at meal times. The nutritional qualities expressed by the frequency of food group intakes were high in the better educated and living status groups, and their eating frequencies of animal protein foods and calcium sources were significantly high. Mealmanagers who had no job intaked vegetable oils through frying foods frequently. The use of health-foods and nutrient supplements was influenced by age, educational and economic level and self-estimated living status, but the trends in prevalence of both were not consistent. Health-foods were prefered by the groups of high educational career, affluent income and advanced living status, and low educational career, low income and low living status groups favored the nutrient supplements. The restrictive intake of animal fat and the use of health-food were positively correlated, which seemed that the subjects used health-foods as supplements in compensation for nutritional unbalance caused by the avoidance of animal protein foods.
The dietary habits and eating behaviors of nonagenarian subjects over 90 years old in Korean representative longevity belts of Damyang, Gokseong, Kurye, Sunchang were evaluated. The subjects of the study were 91 elderly people (26 males and 65 females) over 90 years old and their dietary habits, food preferences and meal patterns were collected by individual interview. The percentage of subjects, who answered 'very good' or 'good' for their health status, was $65.9\%$. In this study, $55\%$ of subjects were without chronic diseases, and there was no significance difference in gender. Many subjects had performed regular exercise and outdoor activity. The rate of eating together with their family was $79.1\%$. Most of subjects ($91.2\%$) had a regular mealtime consuming three meals a day, and they had good appetite and pleasure of eating. The higher preference of food group was fruits ($95.6\%$), legumes ($94.5\%$), mushrooms ($93.4\%$) and vegetables ($92.3\%$), but the amount of intakes is higher in vegetables than the others. Eating with family, regular exercise and self-rated good health are improved their nutrient intakes. Most frequently consumed meal pattern was rice plus soup and side dishes. The side dish consumed frequently was Namul (blanch and seasoned vegetables). From this study, the nonagenarian populations in longevity belt in Korea have good dietary habits such as regular mealtime, constant amount of meal and eat with pleasure. They are taking Korean traditional meal pattern, providing enriched antioxidant vegetable foods. Also, it can be concluded that the amount and quality of diet in the long-lived elderly are responsible for the Korean traditional family system.

Hypertension and obesity are important modifiable risk factors for cardiovascular disease, the leading cause of death in Korea. Therefore, we assessed the association between dietary pattern and obesity in hypertensive patients to formulate health promotion strategies for the older population. Dietary information was collected from hypertensive patients visiting community health education and information center by using 24 hour recall method. The 2005 DRIs for Koreans was used to evaluate the dietary adequacy. When subjects were categorized by body mass index (BMI) as normal, overweight and obese, no significant difference in energy intake was found among groups. Dietary intakes of folate, and vitamin C in obese hypertensive patients were significantly lower than in normal weight patients (p < 0.05). When we compare the nutritional status by waist circumferences, dietary intakes of zinc, vitamin A, thiamin, vitamin C and folate were significantly lower in the obese group. Vegetable intake was significantly lower in the obese group according to BMI as well as waist circumference. Energy intake from carbohydrate was significantly higher in obese hypertensive patients (p < 0.05). Obese hypertensive patients had a higher risk of nutritional inadequacy compared to normal weight patients. Our results indicated the need for developing interventions that encourage greater consumption of vegetables while cutting down salt intake with wise selection of staple foods, for obese hypertensive patients.
This study estimated the status of dietary intake of 258 children from ages 3 to 6 living in Seoul and analyzed the correlation between the degree of children's nutrition awareness and dietary intake, to provide some basic informations on nutrition education program for their health promotion. Average height and weight of the children were 110.5 cm and 19.7 kg. And their body mass index was 16.2 and obesity index was 6.5%. Proportions of carbohydrate, protein and fat to the total calorie intakes were on the average 55.8%, 15.6% and 28.6%. Calorie intake proportion of breakfast, lunch, dinner and snack were 20.9%, 21.9%, 22.3% and 34.9%. In protein intake, proportion of animal and vegetable protein was 1.4, in fat intake pattern, P/M/S ratio was 1.2/1.2/1.0. As a consequence of analyzing the correlation between children's nutrition awareness and dietary intake, children of high awareness degree to the food value did not intake much calorie and carbohydrate, and did not choose cereals and starches, condensed fat food. As a result, dietary intake of pre-school children showed very good but partially showed a problem of over and under nutrition in quantity or in quality we hope that the result of this study could be helpful for the nutrition education program for the health and nutrition of the pre-school children.
