The purpose of this study was to examine height, weight. chest circumference, sitting height, hematological status. eating behaviors and nutrient intakes for the lower grade primary school children in Gwangju. The subjects consisted of 76 boys and 60 girls aged 9 years old. Height, Weight, Chest circumference, Sitting height, Hct, WBC, RBC, Hb, serum GOT, GPT and cholesterol were measured. With regard to regularity of meal time, 66.7% of the subjects has been 'regular'. With regaled to amount of eaten food, 100.0% of the subjects has been 'moderate'. With regard to nutritional balance, 66.6% of the subjects has been 'think,but do not practice'. The study also found that 100.0% of the subjects skipped breakfast, liked korean food. Their dietary intake vase assesed for 1 day by means of 24 hours dietary recall method. The mean energy intake of the subjects was 1,306 kcal. The subjects consumed 47.9g protein, 28.8g lipid, 3.9g fiber, 446.9mg calcium, 835.0mg phosphorous, 7.9mg iron, 3,721mg sodium, 1.863mg potassium, 362.3RE retinol, 0.8mg thiamin, 1.1mg riboflavin, 10.8NE niacin, 93.9mg ascorbic acrid and 173.5mg cholesterol respectively. Energy, protein, calcium, iron, retinol, thiamin, riboflavin and niacin intake was lower than the Korean RDA. There were positive correlations between meal time and protein intake or fat intake or fiber intake or iron intake or retinol intake : negative correlations between meal time and sodium intake negative correlations between saltiness and cholesterol intake positive correlations between use of perilla seeds and riboflavin intake or niacin intake : negative correlations between energy intake or carbohydrate intake or phosphorous intake : negative correlations between frequency of eating-out and protein intake or fat intake or fiber intake or iron intake or retinol intake or thiamin intake or riboflavin intake or niacin intake.

This study was performed to investigate the dietary habit based on residence types of male college students who registered nutrition course for nonmajor. Self reports on dietary habit and one-day dietary records were obtained from 158 male college students in Chungbuk area. The distribution of residence type of male college student was as follows; self-boarding(43.0%), home(41.1%), boarding with meal(12.7%), and others(3.2%). The mean age of subjects were $22.6{\pm}2.5$, and the mean height and weight were $175.0{\pm}5.6cm\;and\;69.1{\pm}9.3kg$, respectively. The dietary habit of male college students considered to be taken more care of, showing indifference to dietary balance, irregularity of meal, and skipping breakfast. One-day dietary records by 24hr recall methods also showed less diverse food intake(mean DVS, 12.7; mean DDS, 3.92). Especially, the students with self boarding residence were more likely not to eat properly, including indifference to dietary balance, irregularity of meal, skipping breakfast, frequent dining-out, high experience of smoking and drinking, and low DVS and DDS. Also the students with self boarding residence seemed not to make a good choice for food, showing high food intake frequency score in canned food, fast food and instant ramyun, while low score in fruit and fishes. More attention should be taken for self-boarding students to recognize the problems in their own dietary behavior, and more practical suggestion to improve their dietary status would be necessary.

Activities of lipoprotein lipase (LPL) and hormone-sensitive lipase (HSL) in adipose tissue, accumulation of carcass fat, and serum triglyceride have been determined in meal-fed (MF) and ad libitum-fed (AD) rats. At each feeding frequency, the animals received diets providing total fat as 15% or 30% of calories and polyunsaturated fatty acids (PUFA) as 2.5% or 11% of calories. The food intake of the MF rats was 75% of that consumed by the AD rats but MF rat utilized their food more efficiently, as evidenced by weight gain per 100 Kcal consumed. Meal feeding, as contrasted to ad libitum feeding, resulted in greater activities of both LPL and HSL. This suggested a higher turnover of fat in the adipose tissue of MF rats. In AD rats, body fat was significantly correlated with LPL and the ratio of LPL/HSL. Meal feeding significantly increased the ratio of LPL/HSL, indicating a greater capacity for energy storage and fat deposition in the MF rat. However, at the limited caloric intake, MF rats failed to realize this potential; there was no significant difference in percentage of body fat at the two feeding frequencies. Body fat deposition was greater in rats fed the 30% fat diet, as compared with the 15% diet, regardless of the rate of food ingestion. This was coupled with a higher ratio of LPL/HSL. The significant correlation of serum triglycerides with body fat and with the ratio of LPL/HSL in AD rats suggests that LPL activity and fat deposition may be controlled by the concentration of circulating triglycerides. Both serum triglycerides and adipose LPL activity were significantly reduced when the diet contained high levels of PUFA. The percentage of body fat was also lower in animals whose intake of PUFA was high.

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.

This study was carried out to investigate the differences of the dietary behavior of the college students by the type of the residence, that is, home-living, dormitory-living, and self-cooking. The responses of 307 students to the questionaire were analyzed. The average meal frequency of the students was 2.4 times a day. Breakfast was skipped most frequently, especially in dormitory-living and self-cooking students compared to home-living ones. Forty-three percent of the students were found to eat breakfast less than twice a week. Such a poor eating habit was mainly due to insufficient time or idleness. When the quality of the meal was evaluated, dormitory-living and self-cooking students had worse scores than home-living ones. The formers had poor dietary habit in terms of balanced breakfast and food diversity of each meal compared to the latter. Fast foods and coffee were consumed more frequently by dormitory-living and self-cooking students than home-living ones. The main food they eat was rice. However, female dormitory-living students had a higher tendency to enjoy bread for breakfast and noodle for dinner compared to the other groups. Home-living and self-cooking students had snack more frequently than dormitory-living ones, and female than male. In terms of snack time, most of the respondents had snack between lunch and dinner or after dinner. The percentage of those who had snack after dinner was greater in dormitory-living and self-cooking students than home-living students. Results of the food preference test showed that their favorite dishes were fruit salad, Bulgogi, uncurdled Tofu stew, Kimbab, and boiled rice. We observed that dormitory-living and self-cooking students had more problems in their dietary behavior. Therefore, they need to learn how to manage their own meals. This study might be helpful to develop nutrition education materials for the dietary improvement of the college students.

This study was designed to investigate the effect of age on the lipid metabolism in the rats fed different diets. In experiment A male Wistar rats of 5 weeks of age and of 32 weeks of age were divided into low fat diet groups and high fat-cholesterol groups. The rats were sacrificed 1 week, 2 weeks and 4 weeks after experiment begins. Also after 4 weeks. the rats in low and high fat diet groups were tube-fed 500mg of choelsterol and were sacrified 3 days later. In experiment b, male Wistar rats of 4 weeks of age and of 6 months of age were divided into 2 groups of butter and cron oil groups. And then eachgroup were divided into 2 subgroups ; meal feeding and nibbling groups . Each diet was fed for 4 weeks. In experiment A, age of the rats and experimental diets did not affect the serum cholesterol and triglycerides concentrations were higher in rats fed high fat cholesterol diet than in those fed low-fat or high -fat diets, but age of the animals had no effect on liver lipid content. The weight and cholesterol content of epidymal fat pad, however were higher in adult rats than in young ones regardless of the diets fed. When the rats were challenged with 500mg cholesterol, the rates of increase in serum and hepatic cholesterol level were higher in adult rats compared to young rats regardless of the diets . On the other hand, the rate of increase of small intestinal cholesterol content was lower in adult rats than in young rats. In experiment B, serum cholesterol and triglyceride content were relatively higher in young rats than adult ones. Stored body lipid was higher in adult rats, as judged by epididymal fat pad weight and total carcass lipid. Meal frequency and the kinds of fat in the diet did not affect the serum choelstero concentration . The serum triglyceride levels. however, was higher in butter fed rats thancron oil fed ones. The cholesterol content of live rand epididymal fat pad was lower in butter fed groups than corn oil groups for both young and adult rats, but there was no difference in liver triglycerides livel.

The purpose of this study is to compare menu patterns by the meal and age (10- 19, 20- 49, 50 - 69, 70 - 84 years old) in Korea rural areas. Frequently consumed menu patterns were investigated using the 24-hour recall method with 1,185 subjects in 5 Korea rural areas for the spring, summer, fill and winter. Results were as follow : most frequently used basic menu pattern, excluding side dish, was rice + soup in breakfast, and was only rice in lunch and dinner. Most frequent menu pattern by the number of side dish was rice + soup + kimchi + 1 side dish in the breakfast and dinner. The Mean Adequacy Ratio (MAR) in the dinner is higher than that of the breakfast. For the 10 - 19 and 70 - 84 years old, frequently used menu pattern was rice + stew + kimchi + 1 side dish. Most frequently used menu patterns, was rice + soup + kimchi + 1 side dish for the 20 - 29 years old, was rice + stew + kimchi for the 50 - 69 years old. MAR with the same menu pattern in 10 - 19 years old is higher than that of 70 - 84 years old. Intake frequency of menu pattern including noodles was higher in 10 - 19 and 20 - 49 years old than that of the other age groups. With these results, for the nutrition program in the community menu patterns should be carefully examined by the meal and age. The result from this study can be used as basic data for nutrition education program in Korean rural areas.

The purpose of this study was to determine the prevalence of obesity and to examine the eating habits of elementary school students in Kwangju. The study was carried out on 931 students(male : 454, female : 477) in September and October of 1996. The results are summarized as follows ; Obesity was defined as body mass index(BMI) that exceeds 20. The rate of obesity was 10.0%(male 4.7$\%$, female 5.3$\%$) in subjects. Subjects were divided into 3 groups : normal group(BMI〈20), mildly obese group(20〈BMI〈25), and moderatly obese group(25〈BMI〈30), respectively. With regard to frequency of skipping breakfast, 9.1$\%$ of normal children and 17.5$\%$ of mildly obese children and 33.3$\%$ of moderately obese children had skipping every morning(p$\ll$0.001). With regard to the regularity of meal time, 62.1$\%$ of normal children had ‘regular meals’but 58.0$\%$ of mild obese children and 50.0$\%$ of moderate obese children had‘irregular meals’(p$\ll$0.05). With regard to meal volume, obese children consumed much more meal volume than normal children(breakfast p$\ll$0.001, lunch p〈0.005, dinner p$\ll$0.001). With regard to try to lose weight, 22.9$\%$ of normal children and 55.6$\%$ of mild obese children and 83.3$\%$ of moderated obese children indicated they had attempted(p$\ll$0.001). The results of this study showed that the prevalence of obesity in elementary school students in Kwangju has a tendency to be increased. Obese children need to correct their eating habits. This reasserts the importance of nutrition education in children through teachers, parents and dietitians. The findings of this study should be applied to nutrition education to ensure better physical fitness of children. (Korean J Community Nutrition 2(4) : 486-495, 1997)

The purpose of this study was to determine the influences on physical status and study achievement by the dietary behavior of the youth in Korea. The survey was carried from June to July, 1995 by way of questionnaire to 397 students. The students' study achievement records and physical status were analyzed by the factor of dietary behavior. The results were as follows: 1 The average physical status of male students was lean, but females were standard. 76ft of mothers of the subjects were working in specialty farming. The monthly income of their family was $1000{\sim}1500$ thousand Won and students' pocket money was $20{\sim}40$ thousand Won per month. 2. The aspects of meal behavior included the general idea that the meal was thought to relieve hunger, and preference of taste was spiciness The most important factor of the meals for the students was taste. Their bad meal habits were quick eating and irregularity of meals. 3. There was a significant difference in the comparison of the study achieving records with the frequency of supper However, there was no one meaningful difference between study achievement records and the attendance rate to school, health status, and living conditions. However, there was a significant difference between their study records and eating with family. The students, who had the breakfast and/or supper with family, remarked better study records than other groups. 4. Also, there was a significant difference of study records with physical status. The overweight or obese students had a lower degree of study score (p<0.1). Adolescence is considered a period of setting up dietary behavior, so it is necessary to educate good nutrition and dietary habits for students to keep in healthy physical condition and with high study achievements.

The purpose of this study was to investigate and compare the consumption behaviors for purchase of Home Meal Replacement (HMR) products and importance and satisfaction on selective attributes of HMR in middle-aged adults by gender. The subjects were 919 middle-aged adults (400 males and 519 females; 40 to 64 years) residing in Seoul and its metropolitan area, who have HMR purchasing experience. The survey was conducted from January to August 2018. Statistical analysis was performed using SPSS 23.0 program. Consumption frequency of HMR products in male and female subjects was 1-2 times a month by 42.3% and 40.8% and 4-6 times a month by 26.8% and 19.8%, respectively (p<0.05). Reasons for purchasing HMR in male and female subjects were shown significantly different from saving time by 44.8% and 50.5% and easy cooking by 25.8% and 16.6%, respectively (p<0.01). HMR products with high preference and satisfaction for the subjects included Gimbap, precooked dried rice, and frozen food. According to the Importance-Performance Analysis (IPA), selective attributes of HMR with high importance and low satisfaction in the second quadrant were food additives, origin, nutrient content, and price, for both male and female subjects; additionally, hygiene was a factor included only by female subjects. Therefore, these results suggest that it is needed to consider to produce HMR products with improved qualities using reliable food materials and ingredients and to maintain competitive pricing for the expansion of HMR products consumption of middle-aged adults.
