Dietary Habits, Food Frequency and Dietary Attitudes by Gender and Nutrition Knowledge Level in Upper-grade School Children: Mi Yong Yon, Young Hee Han, Tai Sun Hyun; Korean J Community Nutr 2008;13(3):307-322. Published online June 30, 2008

Abstract PDF: 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.

Dietary Intake, Serum Lipids, Iron Index and Antioxidant Status by Percent Body Fat of Young Females: Hyun Sook Bae; Korean J Community Nutr 2008;13(3):323-333. Published online June 30, 2008

Abstract PDF: The aim of this study was to measure and compare nutrient intake, anthropometric measurements and serum indices by percent body fat as one of the index of obesity degree in female college students. Additionally we attempted to investigate percentile distribution of fat free mass index (FFMI) and fat mass index (FMI) for developing reference values for these two parameters. The subjects were 91 female college students who were classified to 4 groups according to the percentile of percent body fat (Group1: 25 th < percentile of percent body fat, Group 2: 25 th < or = percentile of percent body fat < 50 th, Group 3: 50 th < or = percentile of percent body fat < 75 th, Group 4: percentile of percent body fat > or = 75 th). The mean percent body fat and body mass index were 28.2%, 20.5 kg/m2 respectively. The mean energy intake was 1707 kcal(81% of KDRIs) and vitamin C, folate, Ca and Zn intake were 73.9%, 54.7%, 79.6%, 97.5% of KDRIs respectively. Most nutrient intake (energy, carbohydrate, cholesterol, fatty acid, Ca, Fe) of G4 was lower than that of G1, G2 and G3. Serum HDL-cholesterol concentration was significantly lower in G4 than G1, G2, G3 and it tended to increase as percent body fat decreased. LDL/HDL, AI of G4 were significantly the highest among the 4 groups and increased as percent body fat increased. The mean fat free mass index and fat mass index were 14.5 kg/m2, 6.0 kg/m2 respectively. The criteria of sarcopenic obesity which has been defined as under 25 th percentile of FFMI and below 75 th percentile of FMI were shown 12.8 kg/m2, 8.2 kg/m2 respectively in this study. In conclusion, we should continue to more systematically research on the studies of new obesity measurement which includes FFMI and FMI as one of the variables. And the public education for weight control that emphasizes both the understanding of body composition and the importance of nutrition balance is also required.

A Study on Nutrient Intakes and Blood Lipids of Middle Aged Men Living in Jeonbuk Province by Percentage of Body Fat: Hye Soon Chang; Korean J Community Nutr 2008;13(3):334-345. Published online June 30, 2008

Abstract PDF: The purpose of this study was to compare nutrient intakes and blood lipids according to the obesity index of middle aged men. Subjects were assigned to one of the following groups based on percentage of body fat (%Fat),; normal weight (10-20% fat), overweight (20-25% fat) and obesity (over 25% fat). Nutrient intakes were evaluated based on questionnaires and 24 hour recall method and blood lipids were analyzed by blood analyzer. The results were as follows: 1) Nutrient intakes were that carbohydrate intake rate in obesity group was lower than normal group and lipids intake rate in obesity group was higher than normal group. The intake of riboflavin and folic acid were differ normal and obesity group (p < 0.05), and normal group ingested under recommended intake. 2) Total-cholesterol, LDLcholesterol and blood pressure in obesity group were higher than normal group but the differences were not significant. The attack rate of coronary heart disease and blood glucose in obesity group is higher than normal group (p < 0.05). 3) The correlation of anthropometric measurements, blood lipid, blood glucose and blood pressure had significant results. Soft lean mass was associated BMI (p < 0.01), TC (p < 0.05), HDL (p < 0.05), LDL (p < 0.05) and SBP (p < 0.05). TG was associated TC (p < 0.05), HDL (p < 0.01), VLDL (p < 0.001) and Risk (p < 0.01). TC was associated LDL (p < 0.01) and Risk (p < 0.01). Blood glucose was associated TC (p < 0.05), LDL (p < 0.05), SBP (p < 0.05) and DBP (p < 0.05). These results suggest that reduction of body weight for the attack risk of obesity group in coronary heart disease.

Comparison of Dietary Patterns by Sex and Urbanization in Different Economic Status: Jihyun Choi, Hyun Kyung Moon; Korean J Community Nutr 2008;13(3):346-358. Published online June 30, 2008

Abstract PDF: The purpose of this study is to find differences in dietary patterns through menu analysis by economic status. The data was obtained from the 1998 and 2001 National Health and Nutrition Survey of Korea. The main variables were economic status, sex, and area by urbanization. The economic status was classified into low, middle, high, and top classes using a poverty line based on the 1998 and 2001 minimum standard cost of living. The areas were divided into metropolis, small city, and rural areas. The dishes of 3 meals were classified into 29 categories by cooking method. The most frequent pattern was "rice + soup + kimchi". The frequency of this Korean basic dietary pattern was the lowest in the top income class and metropolis areas, while the highest in the low income class and rural areas. The frequency of Korean recommended dietary pattern, that is, "rice + soup or stew + kimchi + side dish" was the highest in the top income class. The metropolis group preferred side dishes using meat and a cooking method that saved time, but the rural group preferred side dishes using vegetables and cooking methods that take a longer time. In comparison of dietary pattern between male and female by economic status, the higher economic status, the male's dietary patterns showed more side dishes than those of female. But the main side dish was kimchi in male low class. onsequently, the major dietary pattern in Korea is rice-style, though the western pattern is increasing in the top income class, especially in metropolis areas. Therefore, to make a better dietary pattern, we should develop and spread low-priced recipes of various side dishes and teach financial skills such as ability to make a food budget for lower income classes. Also, we should emphasize the importance of the balance between meat and vegetables and traditional diet and western diet for the top income class, especially in the metropolis areas.

A Survey of Female College Students' Knowledge and Attitudes Toward Breastfeeding: Hyun Kyo Lee, Yong Song, Nam Mi Kang; Korean J Community Nutr 2008;13(3):367-373. Published online June 30, 2008

Abstract PDF: Breastfeeding is an ideal approach for physical and emotional development of babies, as well as recovery of mothers. A breastfeeding education for female students seems to be an effective intervention to increase the Korean women breastfeeding rate. The purpose of this study was to evaluate their knowledge, attitudes, and other related breastfeeding variables for developing a design for a pre-parental breastfeeding educational information for Korean female students of childbearing age. The sample consisted of 205 Korean female college students, ranging in age from 20 to 25 years old. In this study, a self-administered questionnaire included 6 pages with close-ended multiple-choice questions, and included a cover page with 15 questions on demographic characteristics and personal experiences related to breastfeeding. Data analysis was done utilizing inferential statistics using SPSS 12.0 computer program. The findings indicated that breastfeeding education programs should focus on the practical aspect of attitudes toward breastfeeding, and that educational information design should focus on the practical aspects of breastfeeding for all levels of students' education by nurses. Therefore, education for female college students seems to be an effective intervention to increase breastfeeding rate. This study is useful for descriptions of educational activities to help female students develop positive attitudes to breastfeed, to help these students have confidence toward breast-feeding in future by providing correct information and practical techniques on breastfeeding.

Abstract PDF: A study has been performed to provide the basic information about the current dietary habits, health related behaviors, and body indices and to bring forward the importance of this information to the people's attention based upon the relation between employee's life patterns and health conditions in their daily lives. Three hundred and five department store workers were examined from August 2006 to September 2006. With the average BMI values 23.9 +/- 2.2 for males and 20.0 +/- 1.9 for females, both gender groups were in normal, but 62.2% of the males were overweight and 15.4% of the females were under-weight. Regarding dietary and health related factors on how they perceive themselves, as normal were 204 (66.9%) the most and bad and very bad were respectively 43 (14.1%) and 5 (1.6%). Half of the subjects (43.2%) perceived sleeping hours to be insufficient, and 64.4% of them need to exercise regularly. As problems related to eating habits, they reported irregular meal times, overeating, preference of hot and spicy food, skipping meal, unbalanced meals. Regarding weight control they have attempted were the most (73.0%), after weight reduction, 51.2% of the subjects had side effects, such as gastrointestinal troubles, anemia, dizziness, sense of fatigue, constipation, physiological disorder, and diarrhea, etc. In the food habit score, it was shown that overall average score of the subjects was 62.63 +/- 9.86 which is lower than other studies. Female (62.76 +/- 10.15) had better score than male (61.67 +/- 8.06). While the item with the highest point was eat all three meals of the day, that was the lowest point, exercise every day. The food habit score of the younger group had lower than older group, and also they preferred sweet foods to other group. The results suggest that nutrition education for workers at specific working fields needs to be more focused on the improvement of dietary habits and health status of workers.

Do Obese Children Exhibit Distinguishable Behaviours from Normal Weight Children?-Based on Literature Review: Seolhyang Baek; Korean J Community Nutr 2008;13(3):386-395. Published online June 30, 2008

Abstract PDF: Since obesity has been a crucial issue regarding children's health in Korea, numerous studies have been conducted. However, it is difficult to locate studies that can help researchers and/or medical professionals who want to study behavioral differences between obese and normal weight (non-obese) children. The collected literature about obese childrens behaviors were accumulated by performing 'key word' searches from several web engines: 'obesity' 'children obesity' 'behavior' 'habit' 'eating behavior or habit' 'exercise' 'physical activity' and 'daily behavior'. The information was extracted and the behaviors were reviewed utilizing 30 papers that revealed any differences from normal weight children with at least p .05 level of significance. According to those studies, the obese children tended to skip meals more often as a method of losing weight. They also have an increased appetite, eat larger portions and rarely leave food on their plates. The obese children prefer to eat high fat, high calorie foods and eat faster than their normal weight counterparts. Also, the children usually eat alone and eat at irregular meal times. Beside the behaviors related to the standard three meals a day, obese children have high preferences for snacking. The children reported that with pocket money they usually eat certain types of snacks without parent approval. The children stated that they exercise more on a regular basis. However, when asked about their participation they were not likely to engage actively. Meanwhile, they tend to spend free time doing sedentary activities such as watching TV or playing on the computer. Since these studies used self -reported questionnaires with a small sample, size there may be difficulty in forming a basis about obese children's behaviors. Nevertheless, these findings are in accordance with other studies conducted in local as well as western countries. In conclusion, obese children have different daily behaviors or routines from normal weight children. It is recommended that altering these behavioral patterns to match those of normal weight children should be encouraged.

A Study of Hospital Foodservice Satisfaction after Covering Hospital Foodservice in the National Health Insurance: Rah Il Hwang, Jin Hee Kwon; Korean J Community Nutr 2008;13(3):396-404. Published online June 30, 2008

Abstract PDF: This study aimed to evaluate the amount of patients' satisfaction with hospital foodservices among those who were benefited from national health insurance during theirhospitalization. A total of 3,094 inpatients from 191 medical institutions were enrolled in this survey. The survey was carried out from July 23 to September 14, 2007 through the face-to-face interview method. All analyses were made using the SPSS software (version 13.0). The mean age of the participants was 53.3 years, 57.0% were women; 34.7% were high-school graduates. Among the respondents, 30.9% stayed in the hospital for 7~14 days long, and 52.0% were hospitalized in multi-patient rooms for six persons. The 87.7% of total population had a general diet, and 9.6% selected the food menu that was notcovered by health insurance. In addition, 38.3% of patients regarded the fee of foodservice as inexpensive. Overall, the satisfaction score with hospital foodservice was 3.63 on a Likert-type scale ranging from 1 (extremely dissatisfied) to 5 (extremely satisfied). However, the limitations were indicated including the lack of providing nutritional information and quality of taste. In conclusion, the quality of hospital foodservice might not deteriorate even after enforcement of national payment of medical insurance. Further efforts are required for the diversification of menus and legislative work for improving quality of food service for a successful hospital foodservice policy.

A Study on the Sanitation Management Status and Barriers to HACCP System Implementation of School Foodservice Institutions in Seoul Metropolitan Area: Gyoung Mi Kim, Sim Yeol Lee; Korean J Community Nutr 2008;13(3):405-417. Published online June 30, 2008

Abstract PDF: The purpose of the study was to investigate the sanitation management status and implementation barriers of the HACCP system. A survey was conducted based on 760 schools through e-mail after having gone through phone interviews to dieticians in Seoul, Gyeonggi and Incheon areas from December 2006 to March 2007. The following statistics were drawn out from the 459 surveys out of the 760, thus giving a response rate of 60.4% (N = 459). The statistical data analysis was completed using the SPSS program. 92.6% of the respondents operated sanitary education once a month and 67.1% used internet as their sanitary educational source. 50.5% of the pre-preparation rooms were not divided and 78.0% of kitchen floors were always kept wet. Only 15.7% of the respondents used heat and cold insulators and 73.2% of drinking water was natural or purified water. 60.3% of food trays were electronically sterilized and 70.2% of spoons and chopsticks were sterilized by boiling water. The main cause of food-borne diseases was the lack of facilities and equipment (33.1%). Also, the deficiency of facilities and equipment (4.07 points) acted as an implementation barrier of the HACCP system. Compared to Gyeonggi or Incheon area results, Seoul's facilities and equipment (p < 0.001) and implementing barriers of the HACCP system (p < 0.001) results came out relatively high. After the analysis of the implementation barriers of the HACCP system, 91.7% of school principals said it was difficult to apply the HACCP system due to lack of financial support. In consideration to the school foodservice support, solutions for the facilities of school foodservice and a systematic sanitary education of the HACCP system must be made for the employees and everyone else who are related.

Dietary and Non-dietary Factors Related to Bone Mineral Density in Female College Students: Ji Hye Lim, Hyun Sook Bae, Seung Min Lee, Hong Seok Ahn; Korean J Community Nutr 2008;13(3):418-425. Published online June 30, 2008

Abstract PDF: The purpose of this study was to investigate correlations between bone mineral density (BMD) and dietary and nondietary factors in female college students. The BMD of the subjects (n = 38) was measured using DEXA (Dual Energy X-ray Absorptiometry) at lumbar spine and three femoral sites including femoral neck, ward's triangle, and femoral trochanter. Three-day 24-hour dietary recall data were collected from each subject to assess consumption levels of nutrients and food groups. The mean (+/- SD) values of age, age of menarche, height, weight, body mass index (BMI), waist-to-hip ratio (WHR), fat mass, and % body fat of the subjects were 21.34 (+/- 1.73) years, 13.1 (+/- 1.2) years, 161.3 (+/- 5.0) cm, 53.7 (+/- 7.2) kg, 20.6 (+/- 2.6) kg/m2, 0.80 (+/- 0.04), 15.4 (+/- 4.4) kg, and 28.2 (+/- 4.7), respectively. The BMD values of lumbar spine, femoral neck, ward's triangle, and femoral trochanter as T-value were 1.150 +/- 0.13 g/cm2, 0.932 +/- 0.11 g/cm2, 0.850 +/- 0.13 g/cm2, and 0.721 +/- 0.10 g/cm2, respectively. The daily mean energy intake of the subjects was 1660.6 kcal. The intake levels of carbohydrate, calcium, iron, vitamin C, and folic acid were lower than the KDRIs, while those of fat, phosphorus, sodium, vitamin A, and vitamin B6 were higher than the KDRIs. Significantly negative correlation were detected between consumption of fat and oils and the BMD of all sites measured (p < 0.05). Potato and starch intake was negatively correlated to the BMD of femoral neck and word's triangle (p < 0.05). The intake of cereals was found to be negatively correlated to the BMD of ward's triangle (p < 0.05). There was also negative correlation of intake of soybeans and products with the BMD of lumbar spine (p < 0.05). Weight and muscle mass were positively correlated to the BMD of both lumbar spine and femurs (p < 0.01). Significantly positive correlations between BMI, and fat mass and the BMD of lumbar spine were observed (p < 0.001). Additionally fat mass was positively correlated to the BMD of femoral neck. WHR and % body fat were positively correlated to the BMD of lumbar spine (p < 0.05). Negative correlation was found between a serum calcium level and the BMD of femoral neck (p < 0.05). In summary non-dietary factors generally showed significant correlations with the BMD of lumbar spine, while several dietary factors showed significant correlations with the BMD of femurs.

Effect of Prune Supplementation on Dietary Fiber Intake and Constipation Relief: Young Hee Han, Mi Yong Yon, Tai Sun Hyun; Korean J Community Nutr 2008;13(3):426-438. Published online June 30, 2008

Abstract PDF: The purpose of this study was to examine bowel habits, dietary habits, and nutrient intake of constipated adults, and the effects of prune products on relieving constipation symptoms. Fifty one adults with self-reported constipation (mean age 23 years, range 19-41 years, 10 males and 41 females) participated in this study. After a baseline survey on bowel habits and dietary habits, participants were asked to consume at least 50 g of prune and 200 ml of prune juice per day during a 4-week period in addition to usual diet. Nutrient intake was estimated by a 24 hour recall at the baseline and once every week by diet records during the intervention. Data were analyzed after classifying the subjects into mild constipation group and severe constipation group by the severity of the symptoms. During the intervention, the subjects with mild constipation consumed 56 g of prunes (about 5.6 fruits) and 200 ml of prune juice, and the subjects with severe constipation consumed 59 g of prunes (about 5.9 fruits) and 207 ml of prune juice. Average intakes of energy, dietary fiber and water of the subjects in the mild constipation and severe constipation group increased during the intervention compared to the baseline. Average dietary fiber intake of the mild constipation and severe constipation groups significantly increased from 12.5 g and 11.6 g at the baseline to 18.5 g and 16.8 g after consuming prune products, respectively. These changes were accompanied by an increase in the number of bowel movements, a decrease of defecation time, a change to a softer stool consistency, and a decrease of abdominal pain during defecation. Seventy two subjects answered that prune products were effective to improve their overall constipation symptoms. Our data show that supplementation of prune products is effective to provide energy, dietary fiber and water, and to relieve constipation symptoms for constipated adults.

Major Dietary Patterns and Their Associations with Socio-Demographic, Psychological and Physical Factors Among Generally Healthy Korean Middle-Aged Women: Seung Min Lee, A Rim Oh, Hong Seok Ahn; Korean J Community Nutr 2008;13(3):439-452. Published online June 30, 2008

Abstract PDF: This study was conducted to identify major dietary patterns of generally healthy Korean middle-aged women and to examine associations of the dietary patterns with socio-demographic, psychological, and physical characteristics. Data were drawn from the 2001 Korean National Health and Nutrition Examination Survey (KNHANES), which is an ongoing national surveillance system. Healthy female subjects aged 40-64 years and provided the health interview examination and food frequency questionnaire (FFQ) data were included. We conducted factor analysis based on daily mean intake frequency of 26 food groups and identified 3 major dietary patterns, healthy, convenient, and alcoholanimal. The healthy pattern was characterized by higher intakes of fish, seafood, poultry, mushroom, seaweed, vegetable, tomato, potato, and fruit, the convenient pattern by processed meat and fish, ramen, noodle and rice cake, sweet snack, egg, bread, and fast food, and the alcohol-animal pattern by alcohol, poultry, meat, and fish. The healthy pattern was significantly related with higher socio-economic status, more stable family structure, healthier mentality, and sounder status of anthropometric and biochemical variables. Those with higher factor scores for the convenience pattern were found to be younger and having higher socio-economic status, higher subjective levels of health, and lower subjective levels of worry on health. Several physical characteristics significantly improved as the levels of the convenience pattern increased. The alcohol-animal pattern was significantly associated with several socio-demographic characteristics including a low education level, a young age, a small family size, and blue-collar jobs. Public health policy makers can utilize the study findings to select prior target populations with higher needs and to tailor dietary behavioral messages to lower chronic disease risks among Korean middle-aged women.
