This study examined the physical activity and dietary patterns of university students in Nairobi County and compared to their weight status. The study was a cross-sectional analytical design with a sample of 260 undergraduate students randomly selected from two private and two public universities. A semi-structured questionnaire was used to gather information from students. Students weight and height measurements were also obtained. Data was analyzed using SPSS version 22. The study results showed that 53.5% of the students met the recommended levels of moderate physical activity and 18.8% of the students met the recommended levels of vigorous physical activity. Majority of the students consumed fast foods sweetened beverages and pastries most times in a week. The study also showed that 31.2% of the students were overweight and 6.2% were obese. The study reveals that most students did not achieve the recommended levels of vigorous physical activity and showed some poor dietary patterns. Findings show clear evidence of high prevalence of overweight among university students but focus should be on fitness rather than fatness. Efforts should be made to promote physical activity participation and good dietary practices within university environments.

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.

Objectives: This study evaluated the dietary habits and health behaviors of Korean adults according to their physical activity. Methods: Adults aged 19~64 years, who participated in the 2016~2018 National Health and Nutrition Examination Survey, were enrolled in this study. The subjects were classified into the physical inactivity group, aerobic physical activity group, strength exercise group, and combined exercise group. Results: Significant differences in skipping breakfast, frequency of eating out, dietary supplements, and alcohol drinking status were observed among physical activity groups (P < 0.001). The combined exercise group had the highest % KDRI of protein, vitamin A, thiamin, riboflavin, niacin, calcium, potassium, and iron (P < 0.001). The physical inactivity group had the highest obesity rate (35.1%), and they perceived their body image type to be obese. In the combined exercise group, 47.8% of respondents said they were in good health (P < 0.001). The health-related quality of life score of the physical inactivity group was the lowest, with a score of 0.94. The metabolic syndrome risk rate of the combined exercise group was lower at 0.62 times (95% CI, 0.51-0.75) than the physical inactivity group. Conclusions: The physical activity type was associated with metabolic syndrome. These results can be useful for supporting dietary education and physical activity programs for adults.

In the present study, in order to improve elementary students’ nutrition knowledge and form correct eating habits, dietitian in charge executed nutrition education for 4th-, 5th- and 6th-grade students at Namchang Elementary School in Suwon, Gyeonggi-do using various educational media for five weeks and two sessions a week (a total of 10 sessions) through discretional activity classes. 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.

This study was conducted to determine if dietary fiber would reduce exposure of the tissues to dietary benzo[a]pyrene(BP) , a well-known carcinogenic polycyclic aromatic hydrocarbon, as evaluated by benzo[a]pyrene hydroxylase (BPH) activity. The effects of three different sources of dietary fiber(pectin, polydextrose, and clellulose) on BPH activity were studied using Sprague-Dawley rats. In this study, male rats were fed a fiber-free purified diet for 7 days, whereupon they were switched to experimentla diets for 48h. After 48h, their liver, stomach , small intestinal mucosa and large intestinal mucosa were assayed for BPH activity. Thissues exposed to benzo[a]pyrene(400mg/kg diet, fiber-free) showed significant increse in the activity of BPH ; 27 times in liver, 7 times in stomach, 18 times in small intestinal mucosa and 3 times in large intestine. The inhibition in BP -induced BPH activity by dietary fiber in liver, stomach and small intestinal mucosa was observed in the decreasing order : 10 % perctin > 10% polydextrose >5 % polydextrose > 10% cellulose. Decreased BPH induction indicates that soluble dietry fibers, especially pectin and polydextrose in this study, protect the tissues of digestive system from exposure to BP.

The purpose of this study was to identify the effectiveness of a nutrition education program of reducing children's sugar intake based on social cognitive theory. This education program composed of 6 units was conducted in discretional activity class of the $3^{rd}$ and $4^{th}$ grade elementary school students. The results are as follows: First, the rate of correct answers and score of nutrition knowledge significantly increased after nutrition education. The scores of nutrition education in male students, students whose mothers have no job, and students with skinny physiques were much improved after nutrition education(p<0.05, p<0.01, p<0.001, respectively). Second, the dietary attitudes toward reducing sugar intake and checking nutrition labels significantly improved(p<0.05). And also, it tended to decrease in preference and intake of sweet foods. Third, the consumption of candy caramel jelly(p<0.05), yogurt(p<0.05), jam honey(p<0.05), and ice cream(p<0.001) were reduced after nutrition education. Besides, obese students' consumption of isotonic beverages, carbonated beverages, and fruit juice was reduced. Therefore, a positive change in dietary behavior appeared. Based on the above results, we confirmed that the nutrition education program focusing on reducing sugar intake applied with social cognitive theory was effective for improving the nutrition knowledge, dietary attitude and dietary behavior in sugar intake in elementary school students. Especially, this program showed the improvement in nutrition knowledge as well as dietary attitude and behavior in sugar intake among obese children. Since nutrition education during childhood significantly influences lifetime-health and disease prevention, it is necessary to develop theory-based nutrition education program and practice systematic and constant nutrition education in elementary schools.

This study aimed to investigate the effect of the five senses activities involving food ingredients on the eating behavior of infants. The study was carried out four times over 6 months. We surveyed 65 nursery school infants and teachers who were registered at the 2020 Guro-gu Center for Children's Food Service Management in Seoul. They participated in the five senses education specialization project. The results of the study showed that the scores relating to unbalanced diet, hygiene management, dietary attitude, and dietary manners were visibly higher than those before participating in the five senses educational activities. In addition, there was a significant difference in the perception of the food ingredients used in the five senses education activities. Finally, as a result of investigating the types of education used before, during, and after the five senses education activities, and the need for education by type, cooking activities were observed to rank higher than other activities in all questions. Based on this, if dietary guidance is provided through a variety of five senses education activities over a long period rather than as a one-time event, it will be beneficial to the children's healthy eating habits.

This study intends to suggest basic data for the activation of rural activities in dietary life education, through a survey of adolescents on rural activities in dietary life education. It was found that 63.2% of subject students had the experience of rural activities; and that as many as 35.2% among the students who experienced rural activities participated in the activities 5 times or more. And the survey showed that rural activities were led most frequently by a teacher in charge (37.9%), and rather rarely by a nutrition teacher (15.4%) or an expert in dietary life education (7.7%). As for food ingredients that adolescents experienced during rural activities, they were composed of easily available good cookers that are common in the Korean diet, and, among them, vegetables were experienced most, followed by cereals and fruits. On the other hand, as for food ingredients preferred by adolescents, it was found that boy students preferred meat, while girl students preferred fruits. And as for improvements in dietary life, it was found that making efforts to have good dietary habits had the highest score, which shows that rural activities contributed to the improvement in adolescents' dietary life. Therefore, given the fact that rural activities go some way towards improving adolescents' dietary life, it is advisable that more opportunities for experiencing rural activities be provided to adolescents in the future so as to help them have good dietary habits.

The effects of a nutritional education program for first grade middle school students were evaluated from August to December, 2006. The study subjects were 82 boys and 90 girls, residing in Gwangju, Korea. To assess the effects of the nutritional education program, pre- and post-questionnaires examining nutritional knowledge, dietary attitudes, and dietary habits were developed. Paired t-test and repeated measures ANOVA were used to evaluate the effects of the nutritional education program. In the general subject, the main after-school activities were studying, watching TV, and using computer (85.5%), and sports (9.3%), suggesting their low physical activity. Parents (46.5%) were indicated as the source of nutritional education rather than teachers (13.4%). Twenty-five percent of girl students had diet experience of skipping meals (54.6%), suggesting the need of proper nutritional education for adolescents' health care. In dietary attitudes, both genders showed some improvement of recognition after education. In the changes in dietary habits, both genders had a significant effect on 'three meals a day, eating breakfast, and regular meal' after education. After education, the rate of having breakfast everyday increased from 52.4% to 65.9% for boys and from 33.3%to 57.8% for girls. In the changes in nutritional knowledge, the appreciation of the importance of school meals increased in both genders from 50.6% to 80.8% after education. The nutritional knowledge, scores of regular eating and well-mannered eating increased in both genders regardless of the students' characteristics. The study results revealed that this education provided an important motivation to improve basic nutritional knowledge and dietary habit. It is recommended to develop systematic and various educational programs and learning materials tailored to subjects before nutritional education.
