The purpose of this study was to investigate the nutrient intakes, nutritional knowledge, food habits, and lifestyle behaviors of moderately or severely obese children living in the Kyonggi-do area. The subjects in this study were 37 obese children with an obesity index higher than 130% in the forth to sixth grades of elementary school. Anthropometric measurements, 24-hour recall of dietary intakes, and a survey on nutritional knowledge, food habits, and lifestyles behavior were conducted in the 37 obese children (25 boys and 12 girls). The average age, body weight, BMI, and R$\ddot{o}$hrer Index were 12.4 years, 68.6 kg, $29.6kg/m^2$, and 194.9 in boys and 12.7 years, 65.7 kg, $29.8kg/m^2$, and 201.8 in girls, respectively. The percentage of correct answers on nutritional knowledge and nutritional attitude score/max score were 85.8% and 23.0/50 in boys and 87.0% and 17.5/50 in girls, respectively. Except for calcium (85.3%) in girls and calcium (62.7%) and folic acid (83.3%) in boys, the average daily nutrient intakes percentages of nutrients were greater than the DRIs values (107.9~327.3% in boys and 103.0~416.0% in girls). This study showed the existence of some problems associated with obesity, such as higher frequency of skipping breakfast, irregular meal times, unbalanced diet, lack of intake of some nutrients, low nutritional attitude, lack of physical activity, and time management in obese children. These results suggest that a systematic education program including nutritional education on balanced diet, good eating habits and behaviors, and importance of eating breakfast and meal regularity must be emphasized to improve nutrient intakes and food habits in obese children. Obese children also require a more concentrated program that includes physical activity, weight reduction, and weight maintenance strategies to improve their life habits.

The purpose of this study was to determine the effects of nutrient intake, screen time (television viewing and computer and/or video games) and physical activity on obesity in preschool children. Recruitment began in January 2008 by distributing letters to mothers who had children aged 6 years enrolled in daycare. Dietary intakes were obtained from the children's mothers, using the 24-hour recall method. The average height and weight of the children were 114.2 cm and 20.3 kg, respectively. Mean age, body weight, height and Kaup index were not significantly different between groups consisting of boys or girls. Assessment by the Kaup index showed that 14.0% of children were underweight, 69.0% were normal weight, 13.0% were overweight, and 4% were obese. The daily intakes of calcium, potassium, fiber, and folic acid in the group of boys were 77.7%, 58.5%, 80.4% and 88.9% respectively. as compared with the DRIs. The daily intakes of calcium, potassium, fiber, and folic acid in the group of girls were 77.7%, 58.5%, 80.4% and 88.9%, respectively. as compared with the DRIs. Intakes of protein, phosphorus, iron, zinc, vitamin A, thiamin, riboflavin, niacin, vitamin C, and vitamin E were higher than the DRIs. There were no difference among 3 groups (underweight, normal, overweight) in energy or nutrient intake. Preschool children with screen time (TV viewing and computer and/or video games use time) of >2 hours per day had significantly higher Kaup index values, and intakes of energy, carbohydrate, folic acid and zinc. In conclusion, preschool children with reported screen time (TV viewing and computer and/or video games use time) of >2 hours per day were fatter. Therefore, we need further investigate the relation between diet and screen time in preschool children to improve future nutrition education programs. Further studies are required to explore the effects of food intake and screen time (TV viewing and computer and/or video games use time) over a longer period of time.

This study was undertaken to investigate dietary status, food habits, and nutritional knowledge of university students majoring in judo (n=239) and to evaluate the effect of dietary behavior on their athletic activities. Mean daily dietary intakes (3,854.0 kcal) were similar to mean daily energy consumptions (3,975.5 kcal). Average daily intakes of most vitamins and minerals were higher than Korean Recommended Dietary Allowances except for the intake of vitamin A. Self-confidence on judo affected dietary behavior of the subjects: Subjects who had more self-confidence on judo showed more interest in good nutrition and concerned more about foods which could promote their athletic activities. Many side effects were manifested after sudden weight control for judo competition during school days. Therefore, it is suggested that good education on nutrition is necessary not only for athletic students, but also for coaches and trainers of the students. Ten weeks of education on nutrition significantly improved both food habits and nutritional knowledge of the subjects. Food habits were positively correlated with self-confidence on judo. Therefore, it is suggested that improvement of food habits through good education on nutrition would be helpful to improve athletic activities of the students.

This study was conducted to investigate the dietary habits and assess the dietary intake of preschool children. Food habit, preference and nutritional supplement status were investigated using a questionnaire answered by the mothers of 453 subjects aged 3 to 6 years old. Also, a dietary intake survey using a 24-hour recall method was performed by mothers of the children. It was found that 81.2% of subjects had milk, dairy products, cookies, fruit and bread between meals once or twice per day. As well, 60.3% of subjects had an unbalanced diet and 20.7% had an overeating habit. Thus, unbalanced diet was a serious problem for many of the subjects. Due to weight controls, digestion problems and allergies, 11.7% of subjects had special dietary consideration. And 26.4% of subjects were using nutritional supplements. From the 24-recall survey, it was found that all nutrient intakes were higher than the Korean RDA except calcium and vitamin A. Nutrient intakes for protein, calcium, phosphorus and vitamin B2 were significantly different by sex, and also increased with age but not significantly. Children received 35% of daily energy, 44% of daily fat and 52% of daily calcium from snacks, so snacks clearly play an important role in dietary intake. The average number of foods consumed per day by subjects was 17.6 and that dishes was 11.0. Most children consumed 4 or 5 food groups per day. In conclusion, the dietary intake of children aged 3 to 6 were deemed adequate judging from nutrient intake and dietary diversity. More attention should be paid to the nutritional value of snacks in this age group.

This study was performed to evaluate the effectiveness of a nutritional education program conducted by public health center in Jinju city for obese women. The subjects of this study consisted of 27 obese women(BMI $\geq$ 25) aged 35∼55 years in Jinju area, and the educational period was 6 weeks. We evaluated the anthropometric parameters and biochemical indices, dietary habits, dietary behaviors, nutritional attitude of obese women before and after the nutritional education. And also daily intake during the educational period were measured. Weight, obesity index, BMT, waist circumferences and hip circumferences of obese women were significantly decreased(p<0.001) after nutritional education, but changes of WHR, systolic blood pressure and diastolic blood pressure were not significant. There were no significant difference in total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride, LDH and blood glucose level in serum before and after the nutritional education, but the indices tend to decrease after the nutritional education. There was significantly different change of dietary behaviors in 3 items among the dietary behavior after the nutritional education. Their dietary habit, dietary behavior and nutritional attitude scores were significantly improved after the nutritional education. Mean daily energy intakes was low compared with the RDA as 78.88%. The average carbohydrates, protein, fat ratio on the energy intakes was 63 : 17 : 20. The proportion of energy intake from snacks the was 12.91${\pm}$6.15%.

The purpose of this study was to evaluate alcohol consumption and nutritional status in patients with alcoholic liver disease. The subjects were 80 patients with alcoholic liver cirrhosis and 12 patients with alcoholic fatty liver. Also 57 alcoholics without liver disease, 32 patients with viral liver cirrhosis and 194 normal men were included as control groups. Data on anthropometric index, socioeconomic status, alcohol consumption, dietary habits and dietary intakes were collected by individual interview. Alcoholic liver disease group had significantly lower triceps skinfold thickness and mid-uppr-arm circumferences than other groups. Socioeconomic status of alcholoci subjects was middle class or lower than that. The amount, duration and frequency of alcohol consumption were significantly higher and the quality of side dishes consumed with alcoholic beverage was significantly poorer in patients with alcoholic liver cirrhosis than others. Patients with alchololic liver disease ingested approximately 40% of daily caloric intake as alcohol and all alcoholic subjects had lower average intakes of protein, carbohydrates, fat, vitamins and minerals as compared with Korean adult average intakes. The results suggest that alcohol and poor dietary intake could cause malnutrition and might be two of the important risk factors to develop alcoholic liver disease in alcoholics. But other factors like genetic and immunological factors should be also considered in elucidating the causes of alcoholic liver disease. An extensive nutritional education should be emphasized for alcohol consuming population to prevent development of alcoholic liver disease.

This study was performed to assess the nutritional status of low income elderly women aged ${\geq}$65 years residing in Gyeongnam Masan (n=124). Nutrition intakes, food intake frequency, and health-related behaviors including smoking, drinking, and exercise were investigated. Nutrition intake was calculated by the 24-hour recall method using CAN-pro (ver. 3.0). Average daily intakes of energy were $1,142.3{\pm}39$ kcal (71.4% of EER) in subjects aged 65~74 years and $1,071.0{\pm}41.7$ kcal (66.9% of EER) in subjects aged ${\geq}$75 years and the subjects consumed energy less than both 75% of estimated energy requirement (EER). The proportions of energy derived from protein, fat, and carbohydrate were 15.4:15.5:70.6 (aged 65~74 years), and 15.3:13.4:70.8 (aged ${\geq}$75). Nutrients consumed at less than estimated average requirements (EARs) were Ca (60.4%), P (98.4%), Zn (91%), vitamin E (48% of adequate intake, AI), vitamin $B_1$ (63.3%), vitamin $B_2$ (54%), niacin (87.7%), vitamin C (62.5%), and folate (50.5%). Especially, the intakes of Ca (58%), vitamin E (41% of AI), vitamin $B_1$ (60%), vitamin $B_2$ (50%), folate (46.5%), and vitamin C (54%) were 75% less than the EAR for people aged ${\geq}$75 years. According to the food intake frequency survey, the intakes of calcium, milk, fruits, and vegetables were very poor. In conclusion, this study suggests that a nutritional support program for elderly women of low socioeconomic class must be provided by the government to improve the quality of remaining life.

BACKGOUND/OBJECTIVES: This study investigated nutritional status of the elderly with dementia in a care facility with the aim of improving the meal quality of the facility. SUBJECTS/METHODS: Data were collected from 30 dementia patients aged more than 65 years in a long-term care facility in Hongseong. The data were obtained from questionnaires and medical records. The food intake data was obtained using food photographs and the nutrient intakes were calculated using the CAN-Pro 5.0. The data were compared with the dietary reference intakes for Koreans (KDRIs). The nutrient density, diet quality such as nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ), as well as dietary diversity score (DDS) were evaluated. The data were analyzed using SPSS statistical programs. RESULTS: The average daily energy intakes for men and women were much lower than the estimated energy requirements of the KDRIs. The average intakes of energy and most nutrients in the general diet group were significantly higher than those of the other two groups. Significant differences in diet quality and diet diversity were observed according to the meal type groups. The NARs of some minerals (calcium, iron, and zinc) and vitamins (vitamin $B_6$ and folic acid) were less than 0.5 in all study groups. The NARs of protein, iron and MAR of the general diet group were significantly higher than those of the liquid diet group. The DDS scores of meats, fruits and diary food group were very low in all meal type groups, meaning that the diet qualities of the study subjects were not appropriate in all meal type groups. CONCLUSIONS: The food intakes of the study groups showed some limitations by a direct comparison with KDRIs because of the very low physical activities of the study subjects. The diet quality and diet diversity indices suggest the need for improvements in the nutritional quality in all types of diet. Overall, new intervention strategies targeting facility residents with dementia in Korea are needed as soon as possible.

This study was designed to estimate the sodium intake of preschool children . To determine the sodium intake & excretion of preschool children in Korea, dietary behaviors, anthropometry, intakes of dietary nutrients, urinary sodium excretion and preference for salty foods were measured in 42 preschool children (male 26 , female 16, average6.5 years old) and their mothers. The results are summarized as follows. Mean daily urinary sodium excretion was 52.7 mEq(1,212.1mg). This value did not show remarkable change compared with the other studied that were accomplished in the similarage group for about the last ten years. And the subjects showed lower preference for salty taste than those of elementary school children and adults. Mean daily lower preference for salty taste than those of elementary school children and adults. Mean daily urinary sodium excretion were significantly correlated with the frequency of eating out (p<0.01), potassium intake(p<0.001) and urinary sodium to potassium excretion ratio(p<0.001). But there weren't any correlations with mean daily sodium intake, blood pressure, dietary nutrients intake and the preference for salty taste.
