This study was conducted to investigate the change in the anthropometric values, biochemical index, nutritional knowledge, food habits and nutrient intakes in obese children after a weight control program. The subjects of the study were 22 obese children with an obesity index over 120%. The children that participated in this study took nutritional education for weight control along with exercise once a week. The weight control program was conducted for 10 weeks. The BMI, WHR (Waist-Hip ratio), body fat (%) significantly decreased at the end of the weight control program. Total cholesterol and LDL cholesterol were also significantly decreased. The nutritional knowledge scores and knowledge score about obesity were slightly improved. Energy intake significantly decreased from 1768 to 1421 kcal. Intake of Ca, Na, K, vitamin A, vitamin $B_6$, vitamin C and folate increased, while intakes of P, Zn, vitamin $B_1$, vitamin $B_2$, vitamin E and niacin decreased. The distribution of energy intake was significantly changed for the better. The percent fat consumed decreased from 26.5 to 19.7%. In addition, the distribution of energy intake in the meals was changed, where the percent calories consumed during lunch significantly increased from 31.4 to 40.1% and the calorie percentage consumed from snacks significantly decreased from 17.6 to 10.7%. In conclusion, the nutritional education in the weight control program, which was conducted for 10 weeks, was effective in improving the anthropometric values, biochemical index and nutrient intake although nutrition knowledge and eating behaviors only changed slightly. Thus, nutritional weight control programs for obese children should be continuously provided under the proper cooperation of a nutritional teacher at elementary schools.

This study evaluated the evaluate nutrient knowledge of child care teachers and assessed the nutritional level of snacks served in 18 child care centers in Tean-Gun. The survey sample was 18 child care teachers working in 18 child care centers of Tean-Gun. The questionnaire requested information about demographic factors, nutritional knowledge, management status of snacks, and the kinds and serving size of snacks served for 1 week. Data were analyzed using SPSS for windows(version 12.0) and nutritional values were assessed using Can-pro 2.0. The mean score of teachers' nutritional knowledge was 22 out of 30 points. The scores were low in the questions regarding the ease with which Ca and re deficiencies can be developed in infants. The contents of most nutrients supplied from the snacks exceeded 15% of RI(Recommended Intake) but there were significant differences in the contents of energy (p<0.05), protein (p<0.05), fat (p<0.05), carbohydrate (p<0.05) and calcium (p<0.001) between the child care centers. Especially, the difference of calcium between the child care centers was 344.84 mg. These results indicate that a program of relevant nutritional education focusing on snacks needs to be developed for child care teachers, with a special recognition on correct calcium level.

The purpose of this study was to evaluate food safety practices and knowledge of foodservice workers at senior welfare centers. A self-administrated questionnaire was administered to 1200 foodservice workers at senior welfare centers in Seoul, Incheon and Gyeonggi province. Two hundred five responses were returned, with 181 usable for analysis. Statistical analyses were conducted using SPSS for Windows(ver.14.0). Volunteers of respondents comprised 64.1% while chefs and employees comprised 20.9%. Food safety practices were assessed using a 5-point scale(1: strongly disagree - 5: strongly agree), and the average score of food safety practices was 4.27. For specific practices, 'personal hygiene (4.46)' scored the highest, followed by 'cleaning and sanitizing(4.43)', 'separate handing(4.40)', 'cooking process(4.11)', and 'receiving and storing(4.05)'. There were significant differences in the practice average score by age(p<0.01) and experience of food safety education(p<0.01). The total score for food safety knowledge was 14.43 out of 20 points. In the category of food knowledge, 'equipment and facility(80.5%)' had the highest correct answer rate, followed by 'personnel hygiene(75.9%)', 'cooking process(70.4%)', and 'cleaning sanitizing(65.8%)'. There were significant differences in the knowledge total score by job type(p<0.05), age(p<0.05), working experience(p<0.05), chef certification (p<0.01), and frequency of food safety education(p<0.01). The knowledge and practice scores were significantly correlated(p<0.01). This study suggests that food safety education for foodservice workers should be conducted continuously and repetitively, and the development of proper education materials is needed to improve the effectiveness of food safety education for chefs, employees and volunteers at senior welfare centers.

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.

This study was made to find out the relationship between the eating attitude influenced by an eating disorder and nutritional knowledge among 441 female college students. A self-report questionnaire was used, and the summary of the results are as follows : Almost all of the surveyed female college students were in criteria of standard weight, however they regard themselves more obese than what their actual body shape normally shows. The correlation between perceived body shape and the eating attitude influenced by an eating disorder turned out to be high(p<0.001). The significant level of correlation between the perceived body shape and the eating attitude test-26(EAT-26) scores showed much higher than that obtained between actual shape, degree of obesity and eating attitude test-26(EAT 26) scores(p<0.001). There was no significant level of correlation between the defree of obesity and the average score of nutritional knowledge obtained out of the total questionnaire, however it showed significant level of correlation between macronutrient and roughage(p<0.05), fat and calorie requirement(p<0.01). There was significant correlation among perceived body shape, actual weight and eating attitude influenced. by an eating disorder. Thus the correct perception of body shape turned out to be an important factor in obtaining the desirable eating attitude and adequate nutritional knowldege.

This study was conducted to investigate housewives' perception, interest and consumption of health drinks made in a health food stores, and to assess the relationsh- ip between nutritionally-related-variables and the consumption of health drinks. Data was collected from 518 housewives in Chonnam province. Among many items which housewives perceived about health drinks, three factors of 'preference·health-care', ' quality·convenience' and 'price' were found to be represented. Housewives' perception of 'preference·health-care' was negatively correlated with nutritional knowledge. However, a positive correlation between the 'quality·convenience' and eating habits was found. Consumption of health drinks was positively correlated with the diet management score, the perception and interest in health drinks. However, the inverse relationship between consumption of health drinks and nutritional knowledge was observed. Multiple regression analysis showed that the interest and factors of perception of health drinks. Consumption of health drinks was not based upon accurate knowledge concerning nutrition, but was based upon the consumers' perception of taste preference and healthful quality. Therefore, there is a need to educate consumers about the nutritional value of health drinks and how to use nutritional supplements.

This study was carried out to investigate the effect of nutritional knowledge on food habits of male employees in Korea. A questionnaire was developed and distributed to 265 male employees of Seoul and Kyunggi area in Korea. The data were analyzed by t-test and ANOVA using SPSS (ver 12.0). Regarding the general aspects of subjects, the highest percent of ages were between the age 21-30 year old. Most respondents were graduates from a university. About twenty percent of male employees' average income was 1-2 million won per month. Most of their families were nuclear families. Eighty three percent of the respondents did not experience any education on nutrition and obtained food and nutritional information from television and internet. The respondents had a high level of perceived knowledge (86.2%); yet, the accuracy of knowledge was lower than the perceived knowledge (72.31%). Regarding the nutritional knowledge, single groups showed a lower score than married groups and groups living with family. Higher nutritional knowledge correlated with higher educational levels, among man in their twenties and thirties. With regards to their eating habits, the frequency of food intake within a weekly period was significantly different; a large percentage of respondents had high frequencies of instant food, alcohol consumption, and smoking. The higher scores regarding dietary habits were for age groups ranging from 41-60 year old, married individuals, nuclear family groups and educational groups with university degrees. Based on the results of this study, male employees have problem concerning food habits in that they are unbalanced and have a tendency to skip meals. Therefore, for the improvement of nutritional status and eating behavior of male employees, the importance of nutrition needs to be emphasized with proper nutritional education programs.

As for change in nutritional knowledge after nutrition education, 4th-grade students showed improvement by 24.3points(p<0.001), 5th-grade ones by 18.0(p<0.001), and 6th-grade ones by 16.7(p<0.001). With regard to change in dietary habits after education, no effect was observed in the improvement of dietary life but the score of dietary habits was improved as a whole. Nutritional knowledge and dietary habits were in a positive correlation with each other before education(r=0.406, p<0.001), but in no correlation after education. Nutritional knowledge and dietary habit practice plan were in a positive correlation after education(r=0.310, p<0.01). With regard to nutritional knowledge after nutrition education by children’s body type measured using Rohrer Index, knowledge increased significantly in normal children(p<0.001), obese children(p<0.001) and highly obese children(p<0.05) but not in slim children. the effect of education was not significant for children’s dietary habits. Practice plan showed significant changes in all of children(p<0.001). This suggests that nutrition education should be executed from early age. It is necessary to define the goals of systematic nutrition education fit for children’s level and to develop various education programs and teaching materials.

Parents play an important role in the development of their children's nutritional knowledge, attitude and practice (KAP). This study was conducted to investigate and assess the nutrition KAP status related to prevention of childhood obesity for parents of preschool children. 1828 subjects were selected cluster-randomly from 6 kindergartens in the urban of Chengdu, China and were surveyed by questionnaire. The results showed that the rate above $80\%$ of total score were $64.3\%(K),\;89.6\%(A),\;19.5\%(P)$ respectively. The nutrition KAP score of subjects was influenced by their education, gender and age. K, A and P scores were positively correlated with each other. The most expected approach obtained nutritional information for subjects was from newspaper, magazines, lectures and TV. It is concluded that the parents of preschool children in Chengdu indicated the limited nutrition knowledge, imperfect nutrition practice and better nutrition attitude. It is suggested that more nutritional education programs on childhood obesity prevention should be given mainly by newspapers, magazines and lectures in this population.
