The purpose of this study was to compare dietary habit and food preference by obesity index in preschool children. The subjects were 373 children, aged 5 to 6, of 7 preschools in Chungbuk. A questionnaire was answered by the children"s mother. The children were classified into three groups depending on obesity index. Nine percents of the subjects were classified as "obesity", and 12% were "underweight", and 79% were "normal". There was an association with obesity index and eating speed. The percentage of the subjects who responded that they ate very fast were 22%, 9%, and 2% of obese, normal and underweight group, respectively. More children among those who responded that they ate very fast were found to eat until they felt full. The food preference score of the children was high in ice cream, fried chicken, and yogurt regardless of obesity group, but the preference ranking of cooked rice was higher in obese group than in the other groups. Most of the food preference scores in children were significantly correlated with those of their mothers. Our study suggests that preschool children should be advised to eat slowly to prevent obesity. Nutrition education for healthy food choice should be implemented not only for children but also for their parents.

Trienzyme treatment (protease, α-amylase, folate conjugase) before microbiological assay is widely used to measure folate content in foods. The amounts of protein and carbohydrate in foods, however, are varied and the condition of enzyme treatment should be adjusted by food composition. The purpose of this study was to determine the optimal condition of trienzyme treatment for folate assay in muskmelon. The lowest concentration of protease to digest protein in muskmelon was tried to be determined because muskmelon contains only a small amount of protein. Protease and heat treatment did not increase folate assay results of muskmelon at all, which indicates these steeps are not necessary. Therefore, folate content of muskmelon was measured after the treatment of α-amylase and folate conjugase without protease treatment. The average folate content of muskmelon including placenta was 87.5㎍/100g. Folate content of placenta of muskmelon (260.7㎍/100g) was about 6 times higher than flesh alone (64.2㎍/100g). Our results show that muskmelon, especially with placenta, is a good source of folate.

There are many factors affecting the growth and the change of the foodservice industry. Convenience has become a top priority for the increasing number of single households and working women todays. This trend has given a strong impetus to the foodservice operations and they are now providing take-out service. The purpose of this research was to analyse the customer satisfaction with the take-out service of the restaurants. A questionnaire survey of 450 consumers that have experience in take-out service at the restaurants was conducted and 378 completed questionnaires were available for the purpose of the statistical evaluation. Statical analyses were made of raw data by way of using the SAS 8.2 S. Customers" satisfaction scale was composed of 5-Likert scales. The main results of this study were summarized as follows; The customer satisfaction with the take-out service was analyzed according to area, gender and job. The satisfaction score was between 3 point and 4 point among 5 scales. In the satisfaction score according to job, the score in urban area was highly than rural area significantly. In the satisfaction score according to gender, there was no relations significantly in the satisfaction score according to job, there was different significantly in the elements of food taste, price, kindness of employee, knowledge of menu, neatness of employee and access to the restaurant.

This study was carried out to examine dietary habits, food frequency and dietary attitudes by gender and nutrition knowledge level in upper-grade school children. Subjects were 223 boys and 208 girls attending 13 elementary schools (5 th and 6 th graders). A self-administered questionnaire was developed to assess nutrition knowledge, dietary habits, food frequency, and dietary attitudes. Nutrition knowledge score assessed by 19 questions was significantly higher in girls than in boys. There were significant differences between boys and girls in several items in dietary habits such as enough breakfast time, dinner regularity, number of side dishes, eating speed, type of snack after dinner, and degree of saltiness of dishes. Girls consumed staple foods such as rice, noodles or bread more frequently, and consumed less frequently ramyun, fried foods, fast foods, and Chinese foods than boys. In addition, girls had more positive dietary attitudes in trying to reduce fast foods, Chinese foods, ramyun and fried foods. Also children in the high or moderate nutrition knowledge level groups had better dietary habits in frequency of meals, frequency of breakfast, enough breakfast time, dinner regularity, activity during the meal, number of side dishes, eating speed, type of snack after dinner, and better food choices by eating staple foods and vegetable side dishes, meats and beans more frequently, and fried foods, doughnuts/cakes, Chinese foods less frequently, and had better dietary attitudes in breakfast, vegetables and fruit intake than children in the low nutrition knowledge level group. Our results showed that dietary habits, food frequency and dietary attitudes were different by gender and nutrition knowledge level. These results suggest that in developing nutrition education program for elementary school children, the differences between gender and nutrition knowledge level should be considered. Nutrition education in elementary schools may change dietary habits and dietary attitudes through increasing nutrition knowledge.

The objective of this study was to investigate the association of serum homocysteine concentration with folate nutriture, other nutrient intake, and life style factors in college students. Serum homocysteine and serum/erythrocyte folate concentrations were measured in 33 male and 50 female students. Dietary data were collected using a 24-hr recall method for three consecutive days, and other information including life style was collected with a self-administered questionnaire. Mean serum homocysteine concentrations were 7.3 and 6.9 μ㏖/I in male and female students, respectively. Serum homocysteine concentrations were negatively correlated with erythrocyte folate concentrations in males and females. Serum homocysteine concentration was inversely associated with intakes of folate, vitamin B12, vitamin B6, and vitamin C. Mean serum homocysteine concentrations of subgroups who had higher BMI, drank alcohol or coffee more frequently were higher than those of other subgroups. There was no association between homocysteine concentrations and smoking status or exercise. However, the number of the subjects in each subgroup was too small to draw any conclusion. Our study shows that serum homocysteine concentration was strongly related with folate intake and erythocyte folate. In addition, several dietary and other life style factors seem to be important as well. Further studies are needed to confirm these results in a larger Korean population.

Although there has been a significant increase in breast-feeding (BF) rate in Korea, it is plateaued since 2008 and still low compared with that of other countries. Because BF has been related to lower obesity prevalence in many studies and the increase in childhood obesity became evident in Korea, we wondered if a relatively lower BF rate has anything to do with this increase. Therefore, we looked into the relationship between mode & duration of BF during infancy and weight status of toddlers using the data from Korea National Health and Nutrition Examination Survey 2008 through 2011. Number of 2-3 year old toddlers with complete information on BF, anthropometry and normal birth weight was 674. While 87% of them were ever-breastfed, 6.2% each of them were either obese or overweight based on the Standard Growth Chart for Korean Children. Not only the obesity prevalence was different among groups of different mode of feeding, but also the mean duration of BF was significantly longer in normal weight group (9.2 mo.) compared with obese group (5.5 mo.). Accordingly, overweight and obesity prevalence of the toddlers breast-fed for 12 months or longer was significantly lower than that of the toddlers breast-fed for less than 12 months (OR 0.53, 95% CI 0.32-0.87). This study revealed that both BF and duration of BF affect the childhood obesity and, BF for 12 months or longer should be encouraged more aggressively as one of the main strategies to prevent and/or decrease childhood obesity in Korea.

We attempted to define the sources of sodium intake for the Korean population at prepared dish level to provide a basis for developing sustainable nutrition policies and feasible programs for sodium intake reduction. Dietary intake data from 2008 and 2009 Korea National Health and Nutrition Examination Survey was used in the analysis for sodium intake sources. Sodium intake from individual dish consumed by each subject was calculated and used in delineating major sodium sources at dish and dish group level for sub-populations of different sex and age. Also, sodium intake was compared between eaters and non-eaters of some specific dish groups with considerable contribution to total sodium intake. The number of subjects included in the analysis was 18,022 and mean sodium intake was 4,600 mg/capita/day. Major sources of sodium intake at dish group level were in the following order: kimchi (1125 mg, 24.5%), noodles (572 mg, 12.4%), soups (488 mg, 10.6%), stews (399 mg, 8.7%), and cooked rice (284 mg, 6.2%). The magnitude of contribution to total sodium intake by soups and stews was different by age group. Sodium intake difference between eaters and non-eaters was much larger for kimchi group (2,343 mg for male, 1,452 mg for female) than for soups or stews. Interaction between consumption of aforementioned specific dish groups and age was highly significant (p < 0.0005) for both sexes. This study revealed an importance of having not only the control over sodium content of foods/dishes, but also the customized approach for different groups of population to accomplish an appreciable reduction in sodium intake.

Childhood obesity has rapidly increased worldwide and is one of the most serious health problems in this age group. In order to prevent and manage childhood obesity, we developed a nutrition education website. The website consisted of three parts. The first part was made for self-assessment with regard to obesity index, dietary habits, food frequency, dietary attitude, nutrition knowledge, nutrient intake, energy expenditure, and the stage of behavioral change, and tailored messages and advice according to the assessment results. A total of 612 real-size food photos as well as a nutrient database of 3,346 foods and 541 dishes were created to help children estimate nutrient intakes accurately. In addition, an energy expenditure database of 156 activities for children was established to calculate calorie consumption. The second part was made for setting long-term and short-term goals and keeping track of the changes in energy intake and expenditure in one`s own page. The third part was made for education. Various types of nutrition information were provided; texts, pictures, calculators and games. The readability and design of the website were evaluated by 46 obese children. Usefulness, design and readability of the website were found to be desirable for children. This website is expected to be used by an obese child alone or with parents or nutrition teachers in order to control body weight through healthy dietary habits and physical activities. In addition, a non-obese child can also use this website for maintaining healthy dietary habits and preventing obesity. (Korean J Community Nutr 17(4): 390~406, 2012)
