The objective of the present study was to determine the prevalence and type of nutritional ergogenic aids use, and to determine the frequency, reasons for use of nutritional ergogenic aids. Thirty-four male bodybuilders (mean age = 27.0 years), twenty-four male weight lifters (mean age = 20.9 years) participated in the study. Participants completed a comprehensive survey detailing their usage patterns. In this study, 78.1% of bodybuilders and 79.2% of weight lifters reported using nutritional ergogenic aids. The most frequently taken nutritional ergogenic aids, in ranking order, were protein/amino acid powders (79.4%), multivitamin/minerals (67.7%) and creatine (67.6%) for bodybuilders, in contrast to sports drinks (100.0%), protein/amino acid powders (50.5%) and creatine (50.5%) for weight lifters. Over the half of the respondents, 79.4% of bodybuilders and 50.6% of weight lifters, used protein/amino acid powders to gain muscle mass and to stay healthy. Bodybuilders, 67.6% and weight lifters, 41.7%, used multivitamin/minerals to stay healthy and for energy. The intakes of most vitamin and minerals through diet and nutritional ergogenic aids were much greater than RDA. Vitamin $B_1$, vitamin $B_2$, niacin, vitamin $B_6$ and folate intakes were ranged at 400-900%. Vitamin C intake was 1285.4% (for bodybuilders) and 1322.6% (for weight lifters). The correct answer rate of nutritional ergogenic aids was 46.0% for bodybuilders and 52.0% for weight lifters. Both bodybuilders and weight lifters took highly nutritional ergogenic aids and it tended to be taken irrespective of scientific background. Specific sport nutrition education applicable to athletes, especially strength athletes, is recommended. The findings of this investigation could be used to enable the professionals (sports dietician and physician) to identity common misconceptions regarding nutritional ergogenic aids and to implement educational programs.

Objective: The aim was to evaluate roles of vitamin D3 (VD3) and beta-carotene (BC) in the development of esophageal squamous cell carcinoma (ESCC) in a high-risk area, Huai'an District, Huai'an City, China. Methods: 100 new ESCC diagnosed cases from 2007 to 2008 and 200 residency- age-, and sex-matched healthy controls were recruited. Data were collected from questionnaires, including a food frequency questionnaire (FFQ) to calculate the BC intake, and reversed phase high-performance liquid chromatography (RP-HPLC) was used to measure the serum concentrations of BC and VD3. Odds ratios (OR) and 95% confidence intervals (CI) were calculated in conditional logistic regression models. Results: The average dietary intake of BC was $3322.9{\mu}g$ (2032.4-5734.3) in the case group and $3626.8{\mu}g$ (1961.9-5827.9) in control group per capita per day with no significant difference by Wilcoxon test (p>0.05). However, the levels of VD3 and BC in the case group were significantly lower than in the control group (p<0.05). The OR values of the highest quartile and the lowest quartile of VD3 and BC in serum samples were both 0.13. Conclusion: Our results add to the evidence that high circulating levels of VD3 and BC are associated with a reduced risk of ESCC in this Chinese population.

Dietary counseling is undoubtedly important for prevention and treatment of chronic diseases. Several dietary counseling methods have been developed and used in Japan to promote healthier diets. However, in Japan, few studies have established effective counseling methods. We developed a computer-assisted tailored dietary counseling system with self-administered diet history questionnaire (DHQ) to assess nutrient intakes and the feedbacks for counseling. We examined the effectiveness of the system in three studies , two among mildly-hypercholesterolemic and one among healthy subjects. We observed significant changes in intakes of targeted nutrients in all three studies. We also observed favorable changes in the corresponding serum and urinary biomarkers in two studies, i.e., non-significant change in serum cholesterol, serum carotene and vitamin C, and a significant change in 24-hour urinary excretion of sodium. In addition, one of the studies observed a significant modified dietary habit for one-year after the intervention was completed. No unfavorable change was observed for non-targeted nutrients in all three studies. The dietary counseling system with DHQ was concluded to be effective among motivated high-risk and healthy subjects. The system's application to other diseases and populations such as children, adolescents, and elderly, should be examined further. (J Community Nutrition 5(2) : 112-119, 2003)

This qualitative study analyzed various environmental factors and difficulties faced by school foodservices during the COVID-19 pandemic. Focus group interviews were conducted by enrolling 12 nutrition teachers and nutritionists. Data collected were subsequently analyzed for changes implemented during the pandemic, in hygiene management, diet management, and distribution management of the school meal. The content and method of delivery of information related to diet guidance and school foodservice by related organizations were also examined. Results of the survey show that personal hygiene (such as maintaining student-to-student distance, checking students for a fever, and hand disinfection) was duly applied, installation of table coverings and distancing between school cafeteria seats were conducted, and mandatory mask-wearing to prevent droplet transmission was enforced. Depending on the COVID-19 situation, the number of students having school meals was limited per grade, and time-spaced meals were provided. To prevent infection, menus that required frequent hand contact were excluded from the meal plan. Overall, it was difficult to manage the meal plan due to frequent changes in tasks, such as the number of orders and meal expenses. These changes were communicated by nutrition teachers and nutritionists wherein the numbers of school meals were adjusted, depending on situations arising from each COVID-19 crisis stage. Furthermore, in some schools, either face-to-face nutrition counseling was stopped entirely, or nutrition education was conducted online. Parent participation was disallowed in the monitoring of school meals, and the prohibition on conversations inside the school cafeteria resulted in the absence of communication among students, nutrition teachers, and nutritionists. Additionally, confusion in meal management was caused by frequent changes in the school meal management guidelines provided by the Office of Education and the School Health Promotion Center in response to COVID-19. In anticipation of the emergence of a new virus or infectious diseases caused by mutations in the years to come, it is suggested that a holistic, well-thought-out response manual for safe meal operation needs to be established, in close collaboration with schools and school foodservice-related institutions.

In this study, we attempted to analyze the status of meal nutritional management at daycare centers and determine whether the need for improvement varies depending on their size. We divided into two groups based on the size of foodservice facilities. If meals for more than 50 people are provided at a time, they are classified as large-scale facilities (Large-scale group). If they are smaller, they are classified as small-scale facilities (Small-scale group). Dietitians visited each daycare center and checked 5 categories and 14 items. When comparing 5 categories, scores in the Small-scale group scored higher than those in the Large-scale group for 'Menu utilization' category. As a result of comparing the detailed 14 items, the scores of 'Indicate dietary information', 'Use menus suitable for those who are eligible for meals', and 'Posting menus by age in public places at foodservice facilities' were higher in the Small-scale group than in the Large-scale group. As such, there are differences in meal nutritional management according to the size of children's foodservice facilities therefore, it was found that customized education and management were needed according to the facilities' size.

We examined the relationship between breakfast eating, nutrient intake, and health outcomes using dietary intake, anthropometric, and biochemical measurements in Korean adults. Data from the 2007 National Health and Nutrition Survey were obtained, and 2,514 adults aged 20 to 64 years were analyzed. The prevalence of skipping breakfast, using a 24-hour diet recall, was 54.5% in the 20-29 age group, 31.2% in the 30-49 age group, and 19.2% in the 50-64 age group. In the 20-29 age group, waist circumstance and serum cholesterol were significantly higher in breakfast skippers than in breakfast eaters. In the 30-49 age group, breakfast skippers had higher triglyceride levels than breakfast eaters. Energy intake of breakfast skippers in every age group was significantly lower than that of breakfast eaters. Furthermore, in the 20-29 and 30-49 age groups, the percent of energy from carbohydrates in breakfast skippers was significantly lower than that of breakfast eaters, whereas the percent of energy from lipids in breakfast skippers was significantly higher than that of breakfast eaters. Additionally, in the 20-29 and 30-49 age groups, breakfast eaters showed higher carbohydrate and iron intake per 1,000 kcal than breakfast skippers and lower lipid intake per 1,000 kcal than that of breakfast skippers. Breakfast skippers showed intakes of less nutrients than EAR was higher than breakfast eaters except vitamin B2 and calcium intake in males of the 20-29 age group. In conclusion, nutrition education, and policy should be implemented to teach the importance of breakfast, appropriate dietary intake, and proper food choice for each age group.

The purpose of this study was to investigate satisfaction with children's foodservice facilities about program at Center for Children's Foodservice Management (CCFSM) by focusing on differences between associate and regular members. In December 2014, an online survey was conducted at 155 children's foodservice facilities which were enrolled members at CCFSM in Geumcheon-gu, Seoul. The questionnaire included the general characteristics of respondents, satisfaction with CCFSM's services : 'Field consulting', 'Education and training for cook', 'Menu', and 'Newsletter'. The questionnaire was responded by 78 foodservice facilities for children, including 42 regular members (53.8%) and 36 associate members (46.2%). The analysis rate was 50.3% and the majority of respondents were child-care centers (94.9%). As a result, satisfaction with 'Newsletter (4.87 points/5 points)' was the highest while 'Menu (3.95 points)' was the lowest. Satisfaction with 'Education and training for cook' of regular members (4.74 points) was significantly higher than that of associate members (4.41 points). For factors affecting overall satisfaction with CCFSM's service, there was a difference between associate and regular members. Regular members were significantly affected by 'Menu (p<0.001)', and 'Newsletter (p<0.05)'. Associate members were affected by 'Education and training for cook (p<0.05)'. Thus, satisfaction with Menu of CCFSM should be increased. The results of this study show that there was a difference in satisfaction between associate and regular members. Therefore, CCFSM program should be implemented depending on the characteristics of foodservice facilities for children and their needs.
