This study was to investigate the effect of the education about general nutrition knowledge on the acceptance of TV food advertisements in adolescents. Twenty hours of nutrition related education in home economics classes were done during 3 months, to conveniently selected 784 first grade middle school students living in large and small cities and rural areas of Chungnam Province. The education effects were evaluated through questionnaire surveys before and after the education and their comparative analysis. Average TV watching time was $29.2\pm1.16$ hours per day, which was about one hour longer on weekends. Nearly half of the subjects watched TV mainly after 9 PM. After nutrition education, nutrition knowledge scores of total subjects were significantly increased from $7.73\pm2.16$ to $10.25\pm2.51$ with a full score of 16. Food attitude and food habit scores also significantly increased from $32.45\pm4.65$ (full score 50) to $33.93\pm4.68$ and from $36.20\pm5.70$ to $37.29\pm5.87$, respectively. The general acceptance of TV food advertisements scored $25.25\pm4.44$ (full score 40) before education and $26.90\pm4.55$ after education, which was significantly raised by the education. Acceptance scores of TV food advertisements showed significant positive relationships with the scores of nutrition knowledge, food attitudes, and food habits. In addition, TV watching time had negative relationships with nutrition knowledge, food attitudes, and food habits scores, but not with acceptance score of TV food advertisements. The above results suggested that school-based nutrition education improved slightly but significantly the attitude of accepting TV food advertisements maybe through increasing nutrition knowledge and making food attitudes and habits better. Nutrition education focused on the evaluation and acceptance of food advertisements are further needed to improve the TV food advertisement acceptance of adolescents.
This study was done to analyze the contents of food and nutrition information in daily newspapers. Articles in four newspapers(Chosun, Donga, Hankook, Joongang Ilbo) published during November 2003 to April 2004 were monitored. In analysis, 216 articles were used. Classifying the articles by topics, cuisine/cooking $(19.4\%)$ and food/ nutrition related to diseases $(18.1\%)$ were most common. Articles regarding food sanitation or safety, obesity and diet accounted for $12.5\%$, respectively. Other topics in articles included food culture$(11.1\%)$, balanced meals/eating habits $(10.6\%)$ and functional foods $(7.9\%)$. About $77\%$ of articles were written for unspecified persons. Regarding the types of articles, news articles made up $44\%$ of monitored articles, followed by feature articles $(14.8\%)$, advertisement by articles $(12.9\%)$, serials by professionals $(11.6\%)$, and information of daily life $(8.8\%)$. Nineteen percent of articles did not have specific sources, while $20.8\%$ were based on interviews with professionals. Other sources of articles included research reports $(14.8\%)$, field reports $(12.1\%)$ and literature $(8.8\%)$. Contents analysis showed that four-fifth of articles were evaluated as 'contents and titles are consistent', 'not difficult to understand', 'contents are not exaggerated', and 'information is not overgeneralized'. Seventy-one percent of articles were evaluated positively on increasing awareness regarding food/nutrition, while $56.5\%$ were evaluated as providing practical information. The major problems in articles were 'intentional or indirect advertisements of specific items/companies' ($74.6\%$ of articles applicable), 'lacking in scientific basis/explanation' $(65.3\%)$, 'presenting unbalanced information due to focusing on specific area' $(46.7\%)$, 'unclearness of contents' $(38.4\%)$, and 'lacking in explanation of technical terms' $(35.2\%)$. To provide reliable information, stating the sources of articles clearly and supplementing the articles with scientific basis and balanced information on specific topics are needed. It is also necessary to explain the contents and technical terms clearly and to reduce the contents of intentional, indirect advertisement in nutrition-related articles.
The object of this study is to investigate and analyze the quantity and quality of informations on health, food and nutrition reported by newspapers. Six different major domestic daily newspapers(Hankook Ilbo, Donga IIbo, Chosun IIbo, Kyunghyang Shinmun, Hankyoreh Shinmun, JoongAng Ilbo), were monitored from 1st of May to 31st of Oct. 2002.. The results of monitoring in the newspapers were summarized as follows; 1. The total percentage of the articles on health and food nutrition was 2.7% and the percentage of the advertisements on health, food and nutrition was 17.5% of total area of the newspaper. The ratio of the number of food and nutrition topic on the total number of health and food nutrition topic was 35.8% for the articles, was 62.9% for the advertisements. Among advertisements on food and nutrition, the percentage of advertisements on healthy foods was the highest (3,481 or 55.0%). 2. Contents of 340 articles(26.1%) were reported as suitable informations. Contents of 259 articles(19.9%) were reported as inaccurate informations on health, food and nutrition. In the analysis of advertisements, the number of advertisements without sufficient reliable sources was 2,488 cases(23.0%), and with exaggerated contents was 2,268 cases(21.0%). The articles and advertisements should be backed by scientific research or reliable sources and also the opinions of people with expertise in order to report accurate informations to the general public. In order to achieve these results, there should be continuing monitoring activity for the newspapers.
232 internet sites in Yahoo and Empas were monitored to analyze what good contents of nutrition information on line have for the internet searchers. As the sites on line were disappeared frequently, all the monitored sites were selected on April 25, 2003. 3 disciplined personnels analyzed the contents of the selected sites by using self-developed monitoring format. The results are as follows. Most of sites were administered by the marketing companies and only 8% by public institutions, associations and school. Especially, most of the contents of the sites by marketing companies were advertisement about their goods instead of nutrition information. Only 42.6% of sites indicated the sources of nutrition information. Only 10.3% of site administrators responded about on-line questions quickly within 1 day. Moreover, 46% of sites were not conformed their answering periods. On the other hand, 94.8% of sites offered more than 1 feedback methods. Monitors checked purposes offering on-line informations plurally. Leading purpose was for advertising and marketing their goods(59.5%) and 47% of them were opened for offering food and nutrition information. They offered various informations at the same time. More than half of the sites had the menus for food and nutrition information and connected sites, but the other half of them only advertised their own goods. Positive sides from monitored informations were as follows : 'communicating informations easily' (8.7%) / 'definite informations for daily living' (7.2%) / 'beneficial informations for nutritional management' (4.6%) / 'new informations' (2.1%). Negative sides of offered information were ‘not enough to give scientific basis and/or to simplify special evidences too much’(60.8%) / ‘to exaggerate the contents’ (41.4%) / ‘not to indicate the notice of side effect and/or to advertise that there are not side effect from using their goods’ (34.1%).

This study investigated the current tendency of the middle school student's use of the food and nutrition information from the internet web site. The research employed web survey for the national middle school students. Middle school students usually searched the internet information to do homework and to solve the own curiosity. Forty percent of respondents had experience to get food and nutrition information from tile internet, and 74% of them were girl. Cooking method and world cooking exploring were the most wanted information among food and nutrition information. Professional cooking site and tips of food and nutrition from study aiding sites and monthly magazine sites were tile resources of food and nutrition information. The mai or reasons for searching the food and nutrition information were to know the cooking method and out of curiosity. The most unsatisfied problems were unnecessary information, too much advertisement and too difficult contents when the users approached the site to get the food and nutrition information. Students who have been not interested in and had no homework about food and nutrition, had no visiting experience of web sites for food and nutrition information. Therefore, to provide food and nutrition information for teenagers through internet, web sites were developed to have easy contents linked to study aiding site or other sites that teenagers frequently visit. Since teenager's interest about health issues is not as high as adult's one, the contents of sites must be easy for teenagers to follow and fun, however, should be based on scientific facts on food, nutrition and disease.

This study examined the experience of vitamin/mineral supplement among adults in Seoul. Using a self-completed questionnaire including demographic information and use of vitamin/mineral supplement, 618 participants completed the study. The majority of respondents were female (72.2%), 40~49 years old (42.2%), and over college graduates (53.4%). Among the 618 respondents surveyed, 56% had experience of supplement use. The reasons for vitamin/mineral supplement use were health maintenance (56%), fatigue recovery (18%), disease prevention (8%), disease treatment (8%), and nutrition (8%) in order. The main considering factors for selecting vitamin/mineral supplement were side effect, cleanliness and reliability of company. The information sources for vitamin/mineral supplement were physician/pharmacist (45%), TV & advertisement (29%), family and relatives (19%).

This study was intended to help children to cultivate and develop a sound attitude toward food consumption and eating habits through the analysis of food and nutritional information in news articles and advertisements in three major daily children's newspapers in Korea: The Chosen Children's Daily Newspaper, The Hankook Children's Daily Newspaper, and The Donga Children's Daily Newspaper. The monitoring period was for twelve months, January to December 2003. Two hundred seventy-nine articles and three hundred thirty-five advertisements were analyzed. The results were as follows. 'Cooking and health' were the most frequent subject in food and nutrition articles. The articles' contents are evaluated positively in morality and explanation; but negatively in fairness, specialization, and objectiveness. The articles were insufficient in the explanation of professional terms, scientific bases, and practical measures for real life. It therefore seems that they were difficult for children to understand well. The most frequent themes in the advertisements were 'processed fats and sugars' such as chocolate, candies, and cookies. Frequently, they were exaggerated and accompanied by phrases promoting consumption. They did not provide sufficient well-grounded information, and focused too much on events or gifts to instigate consumer sentiment. In conclusion, the most serious problem was that most food and nutrition information in these children's newspapers was lacking in specialization. More specialized and objective information should be provided in order to enhance the educational value of children's newspapers and their utilization in school education programs. Continuous monitoring should be carried out to discover those news articles and advertisements that contain correct food and nutrition information.
This study examined the relationship between mothers' consciousness of diet and their infant feeding methods and weaning practices. Consciousness of diet analyzed from 17 questions concerning the attitudes and opinions of diet was classified into 6 categories using the factor analysis. These categories were the faithfulness of diet, the health-directed dietary practices, the application of health information, the application of information about food and nutrition, the sincerity to meal preparation, and dietary habits. The 400 mothers selected randomly from Wonju area were surveyed. The results obtained from the study were summarized as follows. Weaning was implemented earlier by the group with better education career and with the exact knowledge of weaning. Factors associated with infant feeding methods included some sociodemographic characteristics such as birth order, mothers' employment state and income level and mothers' effort toward faithfulness of diet. The use of health-foods and nutrient supplements were prefered by the groups used bottle-feeding method. The health condition of the infants was influenced by mother's will to carry out the health information rather than infant feeding methods and weaning foods used. Mothers who perceived the importance of diet for health and consumed more milk had healthier babies, and their dietary habits were more favorable. The subjects who self-recognized the meaning of weaning and who believed that earlier weaning was good for baby or delayed weaning was the cause of anemia and poor appetite, took advantage of the information about food and nutrition as well as prefered the health-directed dietary practices. Mothers who retried to feed the weaning food rejected by baby before, applied the dietary information to the real meal management more actively and had a more desirable dietary habits. In those cases the baby had improved health condition. Those who were interested in the meaning of weaning and the nutritious effect of weaning foods, revealed significantly higher tendency on the performance of cooking information and the more confidence to the health information from advertisement.
This study was conducted to analyze how appropriate the on-line nutrition information was externally as a web information. Four-hundred-ninety-seven web sites from 5 internet search engines (Yahoo, Empas, Nate, Hanmir, Naver) were selected on the basis of April 25th, 2004. The skillful personnels monitored them about 8 evaluating categories: clarity, purpose, authority, durability, advertisement, privacy and/or security, responsibility, and contents. Forty percent of the selected web sites were operated by the companies which had commercial purpose like internet shopping malls and 5.6% by academies, societies, research institutions, schools/colleges and public institutions. Most of web sites (76.1 %) were managed for advertisements and sales of companies' commodities, and 32.6% had the food and nutrition information as first purpose. Ninety-three percent of web sites were targeted to healthy individuals through whole life cycle. Specifically, there were lots of web sites for the obesity which were offered by diet related companies. Of the 497 web sites, 193 mentioned the name providing the nutrition information, but only 1/3 had reliability on their specialty. As a source of nutrition information, 52.7% of web sites were using 'books of the major field' and 42.0% 'newspapers' and 23.7% 'broadcasting', respectively. Most web sites mentioned 'setting-up date' but not 'renewal date'. Thirty-six percent of web sites took '2 - 3 days' for the operators to answer the questions through the bulletin. Forty-seven percent of web sites answered' 1 - 10 questions' per 1 week, but 40.1 % of them didn't answer for a week at all. There were 118 web sites (23.7%) to record the connected frequencies and 36.0% of them put the advertisements. Around 96% of web sites mentioned feedback addresses. Among the menus of web sites, 68.0% were about self-advertisement and 64.0% about nutrition information. Each web site was scored to judge its external quality according to the operators by selecting 13 items. Web sites managed by public institution had highest scores (9.5), and lowest in private vendors', food companies' and individual web pages. Among search engines, Naver got the highest score of 7.0 and Nate the lowest one of 6.1. As it was only the pilot study, there were several limits in evaluating tools, time and monitored quantity. To make monitoring of on-line nutrition informatiions actively, standardized monitoring forms might be developed under the integrated studies.
We investigated the association between dietary habits/food group consumption patterns and early risk of metabolic syndrome (MetS), a main cause for metabolic disease. Study participants were recruited from the health promotion center in Dong-A University Hospital and public advertisement. Study subjects (n = 243, 21-80 years) were categorized into three groups: Super-healthy (MetS risk factor [MetS RF] = 0, n = 111), MetS-risk carriers (MetS RF = 1-2, n = 96), and MetS (MetS $RF{\geq}3$, n = 27). Higher regularity in dietary habits (breakfast-everyday, regular eating time, non-frequent overeating, and non-frequent eating-out) was observed in the Super-healthy group than in the MetS-risk carriers, and particularly in the MetS subjects. The relationship between food group consumption patterns and MetS-risk related parameters were investigated with adjustment for confounding factors. Fruit consumption was positively associated with HDL-cholesterol, and tended to be negatively associated with waist circumference, triglyceride, LDL-cholesterol, and insulin resistance (IR). The consumption of low-fat meats and fish, and vegetables was negatively associated with hs-CRP. Specifically, the consumption of seafoods belonging to the low-fat fish was negatively associated with fasting glucose, hs-CRP, and interleukin (IL)-6. Anchovy/dried white baits consumption was negatively associated with fasting insulin and IR. Green-yellow vegetables consumption was negatively associated with fasting insulin, IR, and hs-CRP. On the other hand, sugars and fast-foods were positively associated with LDL-cholesterol. Additionally, fast-foods consumption was positively associated with hs-CRP and IL-6 levels. In conclusion, dietary habits/food group consumption patterns are closely associated with MetS-risk related parameters in Koreans. It may suggest useful information to educate people to properly select healthy foods for early prevention of MetS.
