A Comparative Study on the Dietary Attitudes and Nutritional Status of Preschool Children in Different Income Levels in Busan: Jeong Sook Lee; Korean J Community Nutr 2006;11(2):161-171. Published online April 30, 2006

Abstract PDF: This study was carried out to investigate the dietary attitudes and nutritional status of preschool children in different income levels in Busan. The survey was conducted from November 1 to November 30, 2004 by questionnaires and data analyzed by the SPSS program. The results are summarized as follows: The Kaup index of the upper income class group was higher than that of the other income classes. In the middle income class group, nutrition knowledge scores were higher than in any other income class. Sixty-four point nine percent of the upper income class children, 25.7% of the middle income class children and 15.7% of the low income class children had nutrition education experiences. Intake of protein was higher than that of the Korean recommended dietary allowances (RDAs) for children. In the upper income class group, intake of calcium was higher than in any other income class. Intakes of calcium and iron were lower than those of the RDAs in all children. Dietary attitude had positive correlation with frequency of breakfast, time for outdoor activity, and height and weight, and had negative correlation with frequency of fast food and time for watching television. Frequency of snack had positive correlation with frequency of fast food and time for watching television, but frequency of breakfast had negative correlation with those. These results indicate that nutrition education programs linking parents to children should be carried out to improve their nutritional status.

Abstract PDF: Since the economic crisis in 1997, the number of low income families has increased and the turmoil is likely to affect nutritional and health status of the children in low-income families. The purpose of this study was to investigate dietary behaviors and physical development of low income family children in the Seoul area. The subjects were 44 boys and 56 girls, between the ages of 7 and 12 years, from the beneficiary families of the governmental assistant program and enrolled in after school-care centers. A self-reported questionnaire, including general characteristics and dietary behaviors, was applied to the children and their parents. Skipping meal rate was higher in breakfast than in lunch or dinner, and was less frequent in parents and children families compared to that of the other types of families (p<0.05). Most students are shown that they usually keep the dietary guideline for Korean children. There were significant differences in keeping the dietary guidelines between the parents and children family group and other groups in several items. The results imply that the nutrition education program should be more focused on the families which are not composed of parents and children.

Comparison of Indices for Diet Quality Evaluation of Korean Adolescents by Residence Area and Body Size: Min Young Park, Ji Sook Um, Hwa Jin Hyun, Hae Ryun Park, Young Jin Chung; Korean J Community Nutr 2006;11(2):180-190. Published online April 30, 2006

Abstract PDF: The purpose of this study was to assess several indices of diet quality based on nutrient, food and food group intake of Korean adolescents based on several indices on diet quality according to residence area and body size. Using the data from the 1998 National Health and Nutrition Survey, twenty-four-hour-dietary recalls of a total of 1,110 Korean adolescents aged 13-19 years (male 543, female 567) were analyzed for nutrient adequacy ratio (NAR), index of nutritional quality (INQ), the number of foods (Dietary Variety Score, DVS) and food group consumed (Dietary Diversity Score, DDS). In doing that, it was attempted to apply only the minimum amount of solid foods of Kant's without inclusion of liquid foods because of the very limited variety in Korean foods. Based on weight length index, 13.1% of the subjects were categorized as obese, 14.2%, overweight, 44.4%, normal and 28.3%, underweight. Only vitamin B2 intake was higher in the obese group than in the underweight group. There was no meaningful difference in energy, protein and fat intakes according to the grade of the body size. In terms of residence area, intake of fat, niacin, vitamin B6 and folic acid were lower in the rural areas than in the metropolitan city. Only vitamin E intake was higher in the rural areas. Mean value of NARs (MAR) and INQs (mINQ) was also higher in the metropolitan city than in the rural areas, but there was no significant difference of these two values according to body size of the subjects. Mean DVS was 21.02 for total subjects, and has no difference between male and female and between metropolitan city and other medium-small city. But, the rural areas showed the lowest DVS of 19.05. Mean DDS in which five is a maximum score was 3.3 with no significant difference by sex and by residence area in male subjects. However, in female subjects, DDS in the rural areas was the lowest. According to body size of the subjects, there was no meaningful difference in both scores of DVS and DDS. In conclusion, most indices of nutrient intake and food and food group intake were not significantly different by body size of the subjects, while most indices were significantly different by residence areas: higher in the metropolitan city than in the rural area.

A Study on Knowledges and Attitudes about Breast Milk Feeding and Needs for Breast Milk Feeding Education among High School Students: Kyung Suk Choi, Hee Jeong Lee; Korean J Community Nutr 2006;11(2):191-204. Published online April 30, 2006

Abstract PDF: This study was carried out to investigate the experiences of breast milk feeding information and education, breast milk feeding knowledge and attitude and needs for breast milk feeding nutrition education of high school students to encourage breast milk feeding. The subjects were 565 (male: 250, female: 315) high school students from first to third grade. The results obtained were as follows: In this survey, only 30.0% of subjects experienced breast milk feeding information and only 6.1% of subjects had breast milk feeding education. And the subjects showed the average scores of knowledge of breast milk feeding were 0.29 points of 1 point. Subjects knew well about ingredients of breast milk but they didn't know well about the physiology and method of breast milk feeding and benefits of breast milk feeding for mothers. The average scores of attitude of breast milk feeding were 3.03 points of 4 points, showed slight positive attitudes of breast milk feeding, but they had negative attitudes of emotional and practical aspects. The future plan of feeding practices was breast milk feeding 35.9% and 60.0% of formula milk feeding. A concern was that the students showed high ratio of formula milk feeding plan and they decided by incorrect knowledge of breast milk feeding. The 33.5% of students answered high school students will need breast milk feeding nutrition education, and they thought hospital faculties were the proper educators of breast milk feeding education, but dietitians were recomended as educators because of easy access at school and good knowledge of life-cycle nutrition. Therefore, to encourage breast milk feeding by mothers and supporters of breast milk feeding, breast milk feeding nutrition education is needed urgently among high school male and female students. And nutrition education programs will have to contain benefits of breast milk for babies and mothers and physiology and practical methods of breast milk feeding to improve emotional and practical attitudes for breast milk feeding. Nationwide campaign to promote breast milk feeding at public areas will be needed.

A Study on Weight Control, Nutritional Knowledge, Dietary Attitudes and Eating Behaviors among High School Female Students: Yun Ahn, Hyungmee Kim, Kyungwon Kim; Korean J Community Nutr 2006;11(2):205-217. Published online April 30, 2006

Abstract PDF: This study was designed to examine weight control, nutritional knowledge, dietary attitudes and eating behaviors of 370 high school girls and to investigate if there were differences in these variables by weight control status. The weight control attempters (65.1%) had significantly higher body weight and BMI (p<0.001). The difference between desired and current body weight was -9.1 kg in the attempters, showing a significantly higher difference than the counterparts (p<0.001). The attempters also showed more interest toward weight control (p<0.001), but were less satisfied with their body size (p<0.001). Most of subjects (88.1%), especially in the attempters (96.7%) responded that they would try to control their weights in the future. The regular exerciser was 22.9% in the attempters while the percentage of the counterparts was 11.9% (p<0.05). The use of internet or television watching was not significantly different by weight control status. Subjects scored 15.8 out of 20 on a nutritional knowledge scale, which showed a moderate level of knowledge. The nutritional knowledge score was 15.7 for the attempters and 15.8 for the counterparts. None of the nutritional knowledge items reached statistical significance, although the percentages of correct answers regarding weight control or balanced meals were slightly lower in the attempters. The attempters showed more favorable eating attitudes than the counterparts (p<0.001), especially in the attitudes of applying nutritional knowledge to daily life (p<0.01), attitudes for modifying diets (p<0.01) and importance of having adequate meals (p<0.01). The eating behavior was moderate, with mean scores of 31.1 (possible score: 15-45). Subjects showed problems in eating a variety of foods, eating meals regularly, eating slowly, eating breakfast and consumption of some food groups (e.g., dairy foods, fruits). The attempters consumed seaweeds more frequently than the counterparts (p<0.05). Although there were not many significant differences by weight control status, this study suggested that nutrition education for adolescent girls should be planned to provide nutrition information regarding desirable weight control as well as modifying diets and eating behaviors.

Evaluation of a Nutrition Education Website for Children: Sun Hee Kim, Taisun Hyun; Korean J Community Nutr 2006;11(2):218-228. Published online April 30, 2006

Abstract PDF: This study was carried out to evaluate the usefulness and the effectiveness of the nutrition education website 'ifood (http://ifood.or.kr)' for children. A total of 262 children (5th and 6th graders) participated in the self-education program using the website which consisted of 4 sessions every two weeks. In each session, they were asked to answer some questions on the comprehensiveness of each topic while navigating the website. Nutrition knowledge (20 items), dietary attitudes (7 items), and dietary behaviors (10 items) were evaluated using questionnaires before and after the education. After the education, the usefulness and readability of the website was also evaluated. Most (97.2%) of the responders reported that the education using this website was helpful, 97.3% thought that the contents were reliable, 90.1% responded that the contents were easy to understand, and 88.8% answered that they would revisit 'ifood'. The menus they liked best were "Interesting games" for 35.8%, "How can I cook?" for 17.8%, "How can I become slim" for 16.4%. This website might be more attractive by providing a "greater variety of contents in detail", "more music, motion pictures and images", "more interesting games". After the education, there was a significant increase in nutrition knowledge scores from 10.9 to 13.1. Although the total scores of dietary attitudes and dietary behaviors did not improve, there was a significant increase in each of some questions. These results showed that "ifood", a nutritional education website, was desirable in reliability, aesthetics and enjoyability, and was effective in improving nutrition knowledge and some of dietary attitudes and behaviors in children.

Assessment of Foodservice Management Performance at Child Care Centers: Mee Sook Lee, Jae Yeon Lee, Sun Hwa Yoon; Korean J Community Nutr 2006;11(2):229-239. Published online April 30, 2006

Abstract PDF: This study was carried out to investigate foodservice management practices of 100 child care centers nationwide, and to provide background information for developing foodservice management policies at child care centers. Approximately 20% of the child care centers had a separate dining room; most of the centers were vulnerable to sanitation or safety problems. The percentage of the centers that planned menus was about 60% and 10% established standardized recipes. Fourteen percent of the centers kept records for distribution and menu evaluation and 33% kept sanitation management records. Since only 7% of the centers employed a dietitian, foodservice in most centers were not managed by professionals. The results of menu assessment revealed that 56.5% of the national/public child care centers received 19 points or higher out of 21 points, whereas 5.6% of the private child care centers received the same scores. Proper usage and storage of raw food, sanitary management of equipment and facilities, waste management/leftover food treatment, and basic facility of cooking zones were performed well by many centers. The overall scores of foodservice performance were only 31.2 out of 60 points, representing relatively poor safety management, food procurement management, and facilities and equipment management. These results indicate that the foodservice management of the child care centers are in a relatively poor state. Since nutrition management of the most centers was performed by non-professionals, it may not be possible to provide proper nutrition for health and normal growth of preschool children and to perform efficient nutrition education programs. The following suggestions are strongly recommended in order to improve foodservice performance at child care centers. First, foodservice administration should be performed by a dietitian, and second, efforts should be focused on strengthening nutrition and sanitation management.

Evaluation of the Perceived Performance on Sanitary Management of Cooked Foods in Foodbanks: Yun Kyung Hwang, Ki Hwan Park, Kyung Ryu; Korean J Community Nutr 2006;11(2):240-252. Published online April 30, 2006

Abstract PDF: A survey was implemented to suggest basic data for assuring the safety of cooked foods in foodbank operations. A questionnaire consisted of total 48 items including general characteristics, basic inputs and perceived importance/performance of sanitary management. One hundred twenty-eight responses among the 267 nationwide foodbanks were used for the statistical analysis. About forty-one percent of foodbanks was operated a period of 1-3 years and 43.0% of them were managed by social welfare organizations. The number of staff was only 0.5 person per operation with the whole responsibility and 1.0 with additional work, and thus most of the work was managed by volunteers. Job satisfaction was shown to be moderate and was affected by specialty and salary mostly. The facilities and equipment in foodbanks were not enough to operate and freezers/refrigerators were the top priority to supplement. Most of the respondents attended a nationwide level sanitary education program (79.7%), but complained not enough frequency of education (90%). The sanitary status of the donated foods was considered as satisfactory but some safety practices had to be improved, including personnel expenses and operating costs in the district level, a sanitary awareness of the donors and a general management of the facilities and equipment. An assessment on sanitary management resulted in an overall average of 4.45 out of 5 points in importance and 3.85 in performance showing the high level of sanitation perception in foodbank managers. From the IPA analysis, the fields found to be improved were sanitation management during cooking and temperature control as well as cleanliness and sanitation of both transport vehicle and refrigerator/freezer. To secure the food safety in foodbanks, consequently, personnel support, supplement of facilities and equipment, intense sanitation education and development of sanitation management program is needed.

A Case Study for Pricing Strategy Planning of a Family Restaurant Using Price-Sensitivity Measurement: Mi Kyung Choi, Bong Shik Lee; Korean J Community Nutr 2006;11(2):253-260. Published online April 30, 2006

Abstract PDF: The purpose of this study was to suggest menu pricing strategy based on understanding about customer perceived value of products and services. The technique known as PSM (Price Sensitivity Measurement) was used for analysis of price sensitivity for 3 menu items of a family restaurant in Seoul. A questionnaire was developed through literature review and modified after pilot test. Questionnaires for the main survey were distributed to 250 customers on their visit to the restaurant, and a total of 138 questionnaires were used for analysis (55.2%). The statistical analysis of price sensitivity was conducted using PSM, and descriptive analyses were conducted using SPSS Win (12.0). The main results of this study were as follows: the price sensitivity of beef tenderloin steak was higher than two other menus and the stress range of teriyaki chicken was almost 0, that is, the price sensitivity of teriyaki chicken was very low. Present menu prices of 3 menu items were within the range of acceptable prices, but had some distances from the optimal pricing point. From the result of this study, it was concluded that price adjustment or price promotion strategy would be effective for increase in sales of beef tenderloin steak, and marketing strategies to enhance consumers' perceptions of value should be conducted for all menu items by situations. Overall, PSM technique could be a helpful tool for researchers and managers of foodservice organizations to understand how consumers' perceptions of value are affected by the interaction of price and quality.

Perception of Foodservice Quality Attributes of Older Adults: Compared by Lifestyle and Dining Frequency in Continuing Care Retirement Communities: Sunhee Seo; Korean J Community Nutr 2006;11(2):261-270. Published online April 30, 2006

Abstract PDF: The purpose of this study was to identify the differences of older adults' perceptions of foodservice quality attributes of current offerings in Continuing Care Retirement Communities (CCRCs) in terms of their lifestyles (length of residency, special diet, housing option, travel frequency, dine out frequency), dining frequency, and demographics in the dining room of CCRCs. The survey was administered to residents in three CCRCs. Data was analyzed for 140 surveys using t-test, ANOVA, and factor analysis. This study found female older adults perceived the following attributes were more important than male ones: presentation of food, color and garnish, texture of vegetables, taste and flavor of food, and respectful attitude of serving staff. Older adults who have a special diet perceived the seasoning and bite sized pieces were more important than those who have a general diet. Also, there were significant differences between frequent visitors and occasional visitors in the dining room of CCRCs. By knowing the differences by residents' demographics and residential characteristics, the foodservice manager can establish strategies to increase the dining frequency of residents in the dining rooms of CCRCs.

A Comparative Study on Isoflavone Intakes and Blood Lipids between Hypertensive and Normotensive: Mi Kyeong Choi, Ye Sook Jun; Korean J Community Nutr 2006;11(2):271-278. Published online April 30, 2006

Abstract PDF: It has been suggested that isoflavones protect the cardiovascular system, in part by attenuating blood pressure. The purpose of the present research was to compare the isoflavone intake and blood lipids between hypertensive and normotensive and to examine dietary management for prevention of hypertension. Anthropometrical measurements, blood pressures, nutrients and isoflavone intakes using the 24-hour recall method, and serum lipids of 81 hypertensives and 77 normotensives were estimated. The average age, height, weight, and BMI were 58.2 years, 158.5 cm, 64.3 kg, and 25.6 kg/m2 for the hypertensive and 58.0 years, 159.4 cm, 63.0 kg, and 24.8 kg/m2 for the normotensive, respectively. Systolic and diastolic blood pressures of the hypertensive were significantly higher than those of the normotensive (p<0.001, p<0.001). The daily food intake of the hypertensive was significantly lower than that of the normotensive (p<0.01). The daily energy intakes of hypertensive and normotesive were 1479.8 kcal and 1590.9 kcal and there was no significant difference between the two groups. Carbohydrate intake of the hypertensive was significantly higher than that of the normotensive (p<0.05). However, daily intakes of plant protein, fiber, ash, calcium, sodium, potassium, and vitamin B1 of the hypertensive were significantly lower than those of the normotensive (p<0.05, p<0.01, p<0.01, p<0.01, p<0.05, p<0.05, p<0.05). The daily intakes of daidzein, genistein, isoflavone of the hypertensive were significantly lower than those of the normotensive (p<0.05, p<0.05, p<0.05). However, isoflavone intakes per 1000 kcal showed no significant difference between the two groups. Serum lipids of the hypertensive and normotensive were 189.6 mg/dL and 187.2 mg/dL for total cholesterol, 157.3 mg/dL and 161.9 mg/dL for triglyceride, 42.9 mg/dL and 43.5 mg/dL for HDL-cholesterol, 115.2 mg/dL and 111.4 mg/dL for LDL-cholesterol, and 3.5 and 3.4 for atherogenic index. In the total subjects, there was a significantly negative correlation between systolic blood pressure and genistein intake (p<0.05). Based on these results, we concluded that the daily intakes of food, energy, and isoflavones of hypertensives were lower than normotensives. Therefore, it should be emphasized that proper dietary management considering these dietary factors for prevention of hypertension.

The Outcome of Nutrition Support of Surgery Patients with Hypermetabolic Severity by Total Parenteral Nutrition and Enteral Nutrition and Biochemical Data: Miyong Rha, Eunmi Kim, Young Y Cho, Jeong Meen Seo, Haymie Choi; Korean J Community Nutr 2006;11(2):289-297. Published online April 30, 2006

Abstract PDF: This study evaluated the nutrition intake and changes in laboratory data of surgery patients with hypermetabolic severity on nutrition support. From January 2002 to September 2002, 66 hospitalized surgery patients who had received enteral nutrition (EN, n=19) and total parenteral nutrition (TPN, n=47) for more than 7 days were prospectively and retrospectively recruited. The laboratory data was examined pre-operatively, and on the post-operative 1, 3, 7 day and at the time of discharge. The characteristics of the patients were examined for the hypermetabolic severity, The hypermetabolic scores were determined by high fever (> 38 degrees C), rapid breathing (> 30 breaths/min), rapid pulse rate (> 100 beats/min), leukocytosis (WBC>12,000/microliter), leukocytopenia (WBC<3,000/microliter), status of infection, inflammatory bowel disease, surgery and trauma. The scores for the hypermetabolic status were divided into three groups (mild 0-10, moderate 11-40, severe>41). According to the results of the study, 38.3% (n=23), 45.4% (n=30) and 19.6% (n=13) were in the mild, moderate, and severe groups, respectively. There was a decrease in the serum albumin level and weight loss according to the hypermetabolic severity. However, the white blood cells (WBC), fasting blood sugar (FBS), c-reactive protein (CRP), total bilirubin, GOT, and GPT increased. The nutritional intake was TPN (32.5 kcal/kg, protein 1.2 g/kg, fat 0.25 g/kg), EN (28.1 kcal/kg, protein 1.0 g/kg, fat 1.01 g/kg). The serum albumin, hemoglobin and cholesterol were higher in the EN group than in the TPN group. But the FBS, total bilirubin, GOT and GPT were higher in the TPN group than the EN group. In conclusion, there was a negative correlation between the changes in the laboratory data and the hypermetabolic severity. There was an increase in the number of metabolic complications in the TPN group.
