Lower-Income Predicts Increased Smartphone Use and Problematic Behaviors Among Schoolchildren During COVID-19 Related School Modification: A Longitudinal Study

Background@#As the coronavirus disease 2019 (COVID-19) has continued for a couple of years, the long-term effects of the pandemic and the subsequent school curriculum modification on the mental health of children and parents need to be investigated. To clarify the changes that can occur during one school year and to predict the risk factors for vulnerable groups, this study identified parameters relative to children’s screen time, their problematic behavior, and parental depression. @*Methods@#A total of 186 participants were analyzed who were parents of elementary schoolchildren in South Korea. These parents were required to complete a web-based questionnaire twice. The questionnaires were conducted in June 2020 and September 2021. Participants’ general demographics including family income, children’s screen time, sleep patterns, problematic behavior, and parental depression were assessed via the parental questionnaire that included various measurement tools. @*Results@#Children’s body mass index (BMI) increased significantly in 2021 (18.94 ± 3.75 vs. 18.14 ± 3.30, P < 0.001). Smartphone frequency of use per week (5.35 vs. 4.54, P < 0.001) and screen time per day (3.52 vs. 3.16, P < 0.001) significantly increased during the period of the COVID-19 pandemic. The television screen time (2.88 vs. 3.26, P < 0.001), frequency of viewing (3.77 vs. 4.77, P < 0.001), and children’s problematic behaviors significantly decreased (9.15 vs. 11.85,P < 0.001). A lower income household was a key predictor of increased smartphone frequency (B = 1.840, 95% confidence interval [CI], 0.923–2.757, P < 0.001) and smartphone screen time (B = 1.992, 95% CI, 1.458–2.525, P < 0.001). The results showed that the lower income household (B = 5.624, 95% CI, 2.927–8.320, P < 0.001) and a child’s psychiatric treatment history (B = 7.579, 95% CI, 5.666–9.492, P < 0.001) was the most significant predictor of problematic behaviors of children and parental depression (B = 3.476, 95% CI, 1.628–5.325, P < 0.001; B = 3.138, 95% CI, 1.827–4.450, P < 0.001). @*Conclusion@#This study suggested that children’s smartphone screen time and BMI increased during COVID-19 because of the school curriculum modification following school closures in South Korea. The increased children’s problematic behaviors and parental depression were predicted by lower-income households and the previous psychiatric history of children. These results indicate that multiple social support systems to the vulnerable group are needed during the ongoing pandemic and that a modified school setting is required.

Association Between Suicide Risk and Comorbidity of Mood Disorder and Alcohol Use Disorder:Using Common Data Model in Psychiatry / 신경정신의학

Objectives@#This study determines the effects of comorbidity of mood disorder and alcohol use disorder on suicide behavior. @*Methods@#We converted data from the electronic medical records of one university hospital into a common data model and utilized it in our analysis. We selected 9551 patients with diagnosis codes of mood disorders or alcohol use disorders and divided them into three groups: mood disorder (MD) only, alcohol use disorder (AUD) only, and comorbidity of mood disorder and alcohol use disorder (MD+AUD). The mood disorder group was also subgrouped with depressive (DD) or bipolar affective disorder (BD) groups, and the comorbidity group was classified in the same way. Then, we applied logistic regression analysis to assess the risk of suicide attempts between the diagnostic groups. Subgroup analysis according to age also was conducted. @*Results@#The MD+AUD group had 2.7 (odd ratio [OR]=2.70, 95% confidence intervals [CI]=1.91– 3.81, p<0.0001) and the DD+AUD group had 2.78 (OR=2.78, 95% CI=1.95–3.98, p<0.0001) times higher risk of suicide attempts than the MD only and DD only group, respectively. Furthermore, according to the age subgroup, the risk of suicide attempts was the highest (OR=5.17, 95% CI=2.35–11.40, p<0.0001) in the DD+AUD group for those aged 40–59. There were no significant results in BD. @*Conclusion@#The results showed that the comorbidity of mood disorder and alcohol use disorder could increase suicide risk. This study suggested that alcohol use behavior needs to be assessed as well as mood symptoms for suicide prevention.

A Comparisons of Nutritional Intake and Diet Quality Index-International in Gynecological Cancer Survivors and Normal Women - Using the Korea National Health and Nutrition Examination Survey 2013~2016 - / 대한지역사회영양학회지

Objectives@#The aim of this study was to compare the nutritional intake and Diet Quality Index-International (DQI-I) of gynecological cancer survivors and normal women. @*Methods@#This study compared the anthropometric indices, dietary behavior, nutritional intake, and DQI-I in women with previous history of breast or uterine cancer [Gynecological cancer survivors group (GCSG, n=126)] and normal women [Normal control group (NCG, n=7,011)] using the 2013~2016 Korea National Health and Nutrition Examination Survey data. @*Results@#Body mass index and waist circumference were lower in the GCSG compared the NCG. The frequency of skipping breakfast and eating out was higher in the NCG compared to GCSG. Energy and fat intake were significantly higher in the NCG than in the GCSG, whereas intake of all minerals and vitamins (excluding thiamine), and dietary fiber intake were higher in GCSG. It was observed that the fatty acid intake of the GCSG was significantly lower than that of the NCG. The diet quality evaluation using DQI-I results showed that GCSG was higher in the “within-group” diet variety and adequacy of vegetable group than the NCG, whereas the intake level of the fruit group was higher in NCG. Besides, protein, calcium, and vitamin C intake were higher in the GCSG than in the NCG. The GCSG showed higher levels of total fat and saturated fat moderation than the NCG, whereas cholesterol moderation showed the opposite results. The results of DQI-I comparison according to the cancer survival years showed that the overall score and scores related to diet adequacy and balance were higher in the below 5-year group, whereas the over 5-year group scored higher in terms of moderation of diet. @*Conclusions@#The results of this study suggest that a chronic disease based management approach is needed in cancer survivors. The study provides important data which can help in the preparation of guidelines for long-term lifestyle and diet management, in these patients.

Relation of Nutritional Intake and Allergic Rhinitis in Infants: Using the Korea National Health and Nutrition Examination Survey (KNHANES) 2013~2016 / 대한지역사회영양학회지

OBJECTIVES: This study examined the relationship between the presence of allergic rhinitis and the nutritional intake levels of Korean infants. METHODS: The study involved a total of 1,214 infant subjects aged 1~5 months from the 2013~2016 KNHNES (Korea National Health and Nutrition Examination Survey). The Subjects were classified into two groups based on the presence of allergic rhinitis: Non-allergic rhinitis infants (NARI, n=1,088) and allergic rhinitis infants (ARI, n=126). The general characteristics and family history of allergies, nutrient intake status, nutrient supplement intake, and breast milk and baby food start period data of the two groups were compared. All statistical analyses accounted for the complex sampling design effect and sampling weights. RESULTS: The mean age was 0.5 years old in the ARI group compared to the NARI group. In the residence, the rate of urban was higher in ARI. The family history revealed a significant difference between the two groups, particularly those of mothers rather than fathers. The nutrient intake levels were high in energy, phosphorus, sodium, potassium, iron, riboflavin, niacin, and polyunsaturated fatty acids. Breastfeeding was significantly higher in the ARI group than in the NARI group. The baby food start period was 0.3 months earlier in NARI group than in ARI group. The height, body weight, and birth weight were higher in ARI group than NARI group. The result of Odds ratio analysis showed that excess energy, protein, calcium, phosphorus, iron, riboflavin, and niacin intake increases the risk of allergic rhinitis. CONCLUSIONS: These results can be used as data to develop nutrition guidelines for allergic rhinitis infants.

Nutrients Intake and Health Status by Fruits and Vegetables Intake in Adolescents Based on the 2013∼2015 Korean National Health and Nutrition Examination Survey

This study was conducted to compare the nutrient intake, physical characteristics, and health status according to daily fruits and vegetables intake of adolescents using the Korean national health and nutrition examination survey for the sixth period (2013∼2015). Subjects were 1,096 adolescents aged 13∼18 years. The average daily intake of fruits and vegetables was 518.49±4.94 g. The two groups (insufficient, sufficient) were divided by fruits and vegetables intake (<500 g/day, ≥500 g/day) and the ratio of the insufficient group was 75.9% while that of the adequate group was 24.1%. The mean of intake of energy, calcium, phosphorus, sodium, potassium, iron, thiamin, niacin, vitamin C and dietary fiber differed significantly between the insufficient and sufficient groups (P<0.01, P<0.001). However, there was no significant difference in physical characteristics between groups. The self-perceived health status was better in the sufficient group (P<0.05), while the insufficient group was aware of more stress in their daily life (P<0.05). The serum triglyceride was significantly higher in the sufficient group (P<0.05), while the total cholesterol was lower (P<0.05). As the characteristics of fruits and vegetables are different, it will be necessary to determine standards for consumption of each type. It is also necessary to consider whether a fruits and vegetables intake of 500 g would be a reasonable standard for adolescents. Nevertheless, the results of this study indicate efforts to increase fruits and vegetables intake by young people are necessary.

Eating Behavior, Nutrition knowledge, and Educational Needs of the Food and Nutrition of Elementary School Students in the Gyeungnam Province / 대한지역사회영양학회지

This study was conducted to provide basic data for development of a dietary education textbook and guidebook by investigating and analyzing eating behavior, nutrition knowledge and educational needs in elementary school students. Most of the subjects were eating three meals a day (71.5%) and breakfast (75.3%). The percentage of students who consumed proper amount of meals (49.2%) was low. The percentage of students consuming salty food and fatty foods was 28.6% and 42.1%, respectively. The consumption of meat, fish, egg, bean and tofu was high, while the consumption of vegetables, fruits and seaweed was low. The percentage of students consuming processed food was high, but the percentage reading nutrition labels (34.9%) and hazard analysis critical control point (HACCP) mark (26.9%) when buying processed foods was very low. Total scores of eating behavior and nutrition knowledge were significantly higher in female students than in male students (p < 0.05-p < 0.001). The desirable frequency of the education was once a week (60.5%). The most preferred educational method was 'experiment and cooking practice' (40.1%). The students wanted dietary information as 'cooking' (39.0%). As a result of this study, many problems were found in the eating behavior of students and nutritional knowledge was observed to be low as well. On the other hand, the demand for dietary education was very high. The findings of this study suggested the need for developing dietary education programs in order to encourage proper eating habits of students.

Development of Dietary Life Education Textbook and Teaching Manual for Creative Activities in Elementary School / 대한지역사회영양학회지

This study was conducted to develop a dietary life education textbook and teaching manual for creative activities of elementary school students in middle grade. First, we extracted dietary life related contents from textbooks for third and fourth grade and created systematization of contents involving educational objectives, goals, contents and activities. The development of textbook and teaching manual were based on systematization of contents. The textbook was composed of five major chapters, which were 'nutrition', 'cooking', 'environment and hygiene', 'food' and 'dietary culture'. Each major chapter having six to seven smaller chapters, adding up to a total of 34 smaller chapters. The textbook was in activity format so that can be readily and directly used in actual classes. The textbook had fun characters and various activities (particularly a lot of cooking activities) to deliver the main theme of each chapter. The teaching manual was composed of background, goal, teaching plan and teaching point. The smaller chapters had learning goal, teaching-learning resources, important points, teaching-learning process and reference material. In evaluation after operating the model school, the developed textbooks were suited for students' needs and cognitive level. This textbook can be utilized at creative activities consisting of ten to fifteen students.

Interrelations Among Snack Preference, Purchasing Behaviors and Intake in Upper Grade Elementary School Students: Compared by the Gender and TV Watching Time / 대한지역사회영양학회지

This study was conducted to examine the interrelations among snack preference, purchasing behavior and intake of fifth and sixth grade students in elementary schools in Gyeongnam province. Frequency of snack intake was the highest in those who reported 'once a day' (45.6%) snack habit. Longer-time television viewers also showed higher frequency of snack intake than shorter-time viewers. Thirty-three percent of students purchased snacks by themselves and the frequency of snack purchasing had a significant positive relationship with TV watching time (p 2hr) compared to shorter-time TV viewers and this difference was statistically significant (p < 0.001). The snack preference score was correlated positively (r = 0.454) with the intake frequency for snack and its explanation power (R2) was 20.5%. With regard to snack purchase behaviors, the scores of 'checking the expiration date' and 'comparing the price with similar products' were high (in what group?). Female students (p < 0.001) and shorter-time TV viewers (< 2hr) (p < 0.01) had a more reasonable purchasing behavior. The total score of preference was significantly higher (p < 0.05) in shorter-timeTV viewers (< 2hr). In the correlation between snack purchasing behaviors and intake frequency, attractiveness (r = 0.208, p < 0.001) and preference (r = 0.330, p < 0.001) showed significant positive correlations. The result of regression analysis, preference only was selected (R2= 0.108).

Development of Practical Dietary Education Textbook and Teaching Manual in Elementary School Students / 대한지역사회영양학회지

This study was conducted for researching demand on dietary education of low-level elementary school students and to develop an activity based textbook and a teaching manual on the subject. For necessity of dietary education, 88.8% of subjects answered dietary education is needed. The desirable frequency of the education was once a week (65.7%). The most appropriate time for the education was "school lunch" (37.5%), "special activity" (29.9%), "regular class" (12.4%) and "after school activity" (12.1%). The most preferred educational method was "experiment and practice" (40.1%). The desirable educational materials were "computer materials" (20.7%), "actual objects" (20.1%), "videotapes" (16.5%), "photographs-pictures" (12.2%) and "fairy tales-cartoons" (12.2%). The students wanted dietary information as "cooking" (26.1%), "growth and nutrition" (23.7%) and "right food information" (20.1%). The textbook was composed of five major chapters, which were "Traditional Dietary Culture", "Food", "Dietary Habit", "Hygiene and Environment" and "Cooking". Each major chapter had five to six smaller chapters, adding up to total of 32 chapters. The textbook had fun characters, illustrations, photographs and cartoons to deliver the main theme of each chapter. The textbook was in activity format so that it coul be readily and directly used in actual classes. The teaching manual was composed of background, goals, teaching plans and teaching points. The smaller chapters had learning goals, teaching-learning resources, important points, teaching-learning processes and reference materials. Videos were produced to help cook five snacks in the cooking chapter. Also, "Healthy Song" was created to be used in classrooms. This textbook will be helpful in children's right dietary habits and growth.

Development of Contents and Textbooks for the Education to Reduce Elementary Students' Natrium Intake

This study was conducted to reduce sodium (Na) intake and to establish healthy dietary lifestyles of children. To achieve these goals, we searched, collected, and analyzed the materials related to the Na education, based on which the research personnel-professors and graduate students in nutrition and child education and elementary school teachers discussed to figure out major topics, objectives, and detailed contents and activities appropriate for Na intake reduction. Also a survey was done on the sodium intake and nutrition knowledge of the elementary students. We also organized an advisory committee composed of 15 professionals in related fields to discuss the adequacy and validity of the specific contents. Finally, we systematically organized the contents and developed children's textbooks and teacher's guidebooks. Considering the different cognitive development stages of junior and senior elementary students, we developed two different textbooks for each of them which are easy to read and understand, fun to play with lots of activities, and designed to practice into daily life. The contents cover three major topics-the concept of Na, Na in food, Na in life and are composed of 6 units in total. To help teachers understand and instruct, teacher's guidebook contains an overview of the education, specific information and practical guidelines for each class. We developed these education materials with the aim of lowering children's Na consumption and eventually promoting their health welfare; hopefully we expect these materials would be useful for children's nutritional education in the field.

A Survey on Dietary Habits in Gyeongnam and the Development of the Nutrition Education Curriculum with Teacher's Guide for Obese Elementary School Children

The purpose of this study was to develop a nutrition education curriculum with teacher's guide which includes discretionary activities for obese children. A survey was carried out to investigate the recognition of body image and food behaviors according to the obesity index (mild, moderate, severe) in school children (4~6th grade, 158 boys and 60 girls) who were selected based on a physical examination in May, 2006 in the Gyeongnam province. Next, a nutrition education curriculum with teacher's guide was developed on the basis of the findings from the survey and from preceding researches. The results are summarized as follow. The results of this study showed the existence of some nutritional problems such as overeating, prejudice, skipping meals, snacking patterns, etc, which indicate the need for nutritional management for obese children. Most overweight children (80.3%) showed the most interest in the nutrition education program, particularly with regards to dieting for weight control (64.7%). The developed nutrition education curriculum consisted of 8 main subjects and 13 subtitles. The curriculum was prepared for 13 lessons and included songs and singing, making-up lyrics, games about nutrition, discussions of the experience of eating (satiety, thirst, hunger), debates on dietary habits, writing and others to promote the interest for learning. We aimed to develop this program in an attempt to improve the dietary habits of obese school children. This is very important because once a dietary habit is formed in adults, it is difficult to change and the best adjustable stage is during childhood. Therefore, early nutrition education during elementary school can change and build-up the awareness of health in young elementary school children.

The Weight Control-Related Attitudes, Dietary Self-Efficacy and Eating Behaviors according to the Perception of Eating Disorder and Obesity Index in Dancing Major High School Girls / 대한지역사회영양학회지

This study was performed in order to compare the differences in dietary self-efficacy and eating behaviors as well as the relationship of weight control attitudes according to eating disorder perception and obesity index for high school girls majoring in dance. Almost half (45.5%) of the subjects perceived eating disorders, and the rate of underweight group was 45.7%. Forty-four percent of the group that perceived eating disorders were in modern dance, while 55.0% of the group that did not perceived eating disorders were in Korean dance (P <0.05). For the obesity index, a similar rate was shown between the different types of dance for the underweight group, but in the normal group, 54.5% were in Korean dance (P <0.05). Most (82.0%) of the group that perceived eating disorders had fears on obesity, while only 53.3% of the non-perceiving group had fears on obesity (P <0.01). Over half (58.3%) of the underweight group had fears on obesity, while 77.2% of the normal group showed fear in that (P <0.05). For necessity of weight loss to do dance performances, 25.0% of the underweight group and 57.9% of the normal group need that (P <0.05). Most of the group that perceived eating disorders (92.0%) answered that they had experience in very low calorie diets, while only 40.0% of the non-perceiving group had experience (P <0.001). For necessity of calorie education, 42.0% of the group that perceived eating disorders and only 20.0% of the non-perceiving group answered is needed (P <0.05). For eating behavior , the group that perceived eating disorders had lower total scores compared to the non-perceiving group (P <0.001), The group that perceived eating disorders showed lower scores for restraint eating (P <0.01) and emotional factors (P <0.001) except by external eating. This study showed that high school girls majoring in dance have high interest in weight control and problems with wrongful body images and eating behaviors, as well as need for calorie education were suggested. Thus, it is necessary to develop and execute a proper weight control education program for the subjects.

Interrelations Among Beverage Intake, Food Behavior and Personality in Adolescents / 대한지역사회영양학회지

This study investigated the influences of the beverage intake on food behavior and personality for 1295 adolescents. The results were as follows. The favorite beverage was 'fruit juice', and preference of 'coffee' was the lowest. 'Milk and dairy product' was highest and 'milkshake' was lowest in intake frequency of beverage. The preference correlated positively(r = 0.391) with the intake frequency of beverage, especially high in 'green tea and black tea'(r = 0.622), 'coffee'(r = 0.581), 'carbonated drink'(r = 0.538), and 'milk and dairy product'(r = 0.501). The explanation power(R2) of beverage preference on beverage intake was 0.153. The explanation power(R(2)) of beverage intake on food behavior was 0.127, and 'carbonated drink' and 'coffee' as well as 'milkshake' had a negative influence on food behavior: however, 'milk and dairy product', 'green tea and black tea', and 'fruit juice' had a positive influence on food behavior. The relationship of beverage intake and sociality was very low(R(2)= 0.013), and 'isotonic drink' and 'green tea and black tea' had a positive influence on sociality. The relationship between beverage intake and anger expression was also very low. 'Coffee' showed a positive relationship with anger-in. 'Carbonated drink' and 'milkshake' showed a positive result with anger-out. 'Milkshake' showed a negative relation with anger-control, but 'green tea and black tea' and 'milk and dairy product' showed a positive relation. From these results, it was necessary to develop the practical nutritioneducation program on proper beverage choice for adolescents leading to better metal and physical status.

Interrelations Among Fast Food Intake, Food Behavior, and Personality in Adolescents / 대한지역사회영양학회지

Especially, the teenage period, an important lifetime to develop both physically and mentally, needs to be helpful to promote the growth of the body and to keep a well-balanced mind through a balanced and nourishing diet. It is well known that the western style fast food is the most liked meal by teenagers. Wrong recognition about fast food and its frequent intake by adolescents can lead to unbalanced diet and food behaviors which may also connect with a poor impact on their personalities as well as their physical health. In this study, therefore, relationships between fast food intake frequency and food behavior, sociability, and personality, such as anger expression, were surveyed from 1,295 adolescents (666 in Seoul, 316 in Changwon, and 313 in rural communities), and then analyzed using SPSS program. The results are shown as follows. The fast food preference score and the fast food intake frequency score showed no differences between male students (22.9/30, 14.4/30 respectively) and female students (23.0/30, 14.0/30 respectively). But, the fast food preference score correlated positively with the intake frequency score (r = 0.304) significantly (p < 0.001). The more frequently eating of fast food group showed significantly lower scores (r = -0.233, p < 0.001) in food behaviors. The frequency of fast food intake had no relationships with sociability, but it had a significantly effect on anger expression (r = 0.213, p < 0.001) and control (r =-0.147, p < 0.001). From these results, we could see the necessity of various nutrition education programs to build proper eating-out habits and also more studies are needed to find the relationships between fast food intake and growth and personality.

Development of the Computer-assisted Nutrition Education Program of Eating-out Guidance for Teenagers / 대한지역사회영양학회지

This study aimed to develop a nutrition education internet program for correcting the eating-out behaviorial problems of youth. A survey was performed to investigate the eating-out behavior patterns of youth by questionnaires. A nutrition education program was developed on the basis of the survey results, and evaluated by teenagers. The results of the developed homepage are summarized as follows: The contents of this program (www.health14.net) consist of 'x Health (Teenager, My Health, Healthy life, Beautiful life)', '+ Nutrition (To find slow foods, Fast foods campaign, Selecting fast foods, The best menu for eating-out, Recipes for health, Golden bell nutrition quiz)', '/ Information (Diet mini-homepage, Q & A, My knowhow, Game, Community)' and 'Basic Menu (home, Log in, Information and news, Mini-homepage, Site map, Free bulletin board)'. It can be used as educational material for dietary behaviorial changes in school. Also teachers and parents could get information on eating-out menus. Through this site, we anticipate contributing to nutritional health promotion by correcting the eating-out habits of youth.

Effect-Evaluation on Nutrition Education in Related Curriculums for Elementary School Children: Focused on Change of Dietary Habits / 대한지역사회영양학회지

The purpose of this study was to develop of nutritional education activities and effect evaluation in related curriculums for all Dongbu Elementary School children in Jinhae by the teacher in charge. This educational purpose was to build a desirable dietary behavior for optimal growth and health in elementary school children. The educational program contents were developed according to 1) selection of content related curriculums 2) analysis of contents related on dietary habits by grade 3) preparation teaching plans to build desirable dietary habits 4) development of teaching manual by turns. Twelve hours of nutrition education at all school classes were done from March 2 to December 10 2004 in Dongbu Elementary School in Jinhae, Gyeongnam. The education effects were evaluated through the questionnaire surveys before and after the education and their comparative analysis. The results of this study were summarized as follows : Forty percent of the underweight group, 22.8% of the normal group, 42.2% of the obese group had the wrong perceptions on their body figures, but after nutrition education 80.5% of the underweight group, 94.3% of the normal group, 97.9% of the obese group gleaned the correct perceptions on their body figures (p<0.001). As the effects of the education, the subjects who exercise more than 3 times in a week increased in all groups (p<0.01 - 0.001), notably in the obese group. Meal regularity (p<0.001), skipping meals (p<0.001), eating rate and snack selection patterns (p<0.01 - p<0.001) also improved by nutrition education. We could also observe the effects of the nutrition education through the affirmative statements which appeared in their dietary records. These results showed a possibility of nutrition education activities in related curriculums to improve in dietary habits of school children. Next year, we will start with the system of nutrition teachers in elementary school, but nutrition teacher cannot undertake the task of teaching and food service management alone. Because of that, we intend to develop this program as an alternative proposal for the nutrition education in elementary schools.

Development of Nutrition Education Textbook and Teaching Manual in Elementary School

Health is easily overlooked because it doesn't be changed good or bad due to sudden effort or indifference unexpectedly but kept in daily life. Especially, schoolchildren period, an important lifetime to develop both physically and mentally needs to be helpful to promote the growth of the body and keep well-balanced mind through balanced and nourishing diet. The purpose of this study was to develop nutrition education contents for discretional activities in elementary school. The present educational contents about food and nutrition was analysed in the curriculum of elementary school. The results showed the Korean language(20.8%) included an highest ratio in educational contents about food and nutrition, the next was the courses of physical education and wise life(18.1%, each). As the educational contents about food and nutrition in the textbook were dealt with food information (20.8%), Health.Disease(15.3%), and correct dietary habits by order. We could found more contents in the text for the higher classes than for the lower classes. But the most of the contents appeared lack of structure, profundity and continuity for the systematic nutrition education in its entirety. The developed nutrition education contents for discretional activities in this study consist of korean dinning cultures and foreign dinning cultures, correct dinning etiquette, how to choose healthy food, personal sanitary and health, nutrients and food tower, and problem for children's nutrition as main subject. This six main subjects were composed of 23 subtitles. The teaching manual consisted of the educational goal, background, teaching plan and effect-evaluation plan, and the notice point for the effective lesson. The teaching plan was made for 30 hours and consisted of cooking course, singing/making lyrics, games in nutrition, debate on dietary habit, and role play etc which are oriented to practical learning. We intended to develop this program that attempts to improve in dietary habit of schoolchildren. It is because once formed an adults dietary habit is difficult to change. Schoolchildren's period is the best adjustable stage. Therefore, nutrition education in elementary stage can change to dietary habit and build the awareness of health.

Effect-Evaluation of Nutritional Education Program Using Internet for School Children

This study was carried out to evaluate the effects on elementary school children of Internet-based nutrition education programs. The subjects consisted of 80 boys and girls (book-loaming group : 42, Internet-based teaming group : 38) in the 5th grade of elementary school. The results were as follows : The evaluation of Internet-based education programs by Internet-teaming group showed above average in all domains. As the favorite and wholesome menu chose 'nutrition kingdom' (52.6%) made of animation. The educational effect of this program was evaluated by comparing the methods of the Internet-learning group with those of the book-learning group. For effect-evaluation were measured the degree of nutrition knowledge and diversity score of dietary intake from before and after education. Before undertaking the program, there was no significant difference between the two groups in terms of their nutrition knowledge. However, the nutrition knowledge of the Internet-based teaming group after the program had increased significantly (p<0.01) compared to the book-learning group. There was no significant difference between the two groups in terms of the diversity of dietary intake before the start of the program, but upon its completion, the Internet-based learning group showed a significant increase compared to the book-loaming group (p<0.05). This suggests that Internet-based educational programs could be effective in drawing the interest and boosting the concentration levels of schoolchildren. In conclusion, Internet-based nutrition education shows the potential to be an effective alternative education method.
