The purpose of this survey was to study nutrition knowledge, dietary attitude, residences and purpose value of meal in the college freshmen. The survey was conducted from May 1 to May 25 in 1997. The results are summarized as follows. The female students showed higher scores than male students in nutrition knowledge score, but there was no difference in dietary attitude. Dietary attitude of the students living in home were higher than that of the other students. Female students tended to choose food for the pleasure of its taste. On female students, no difference was founded on nutrition knowledge and dietary attitude with purpose value of meal. The male students who have purpose value of meal on intake of nutrients showed the highest score in nutrition knowledge.

The purpose of this study was to identify the factors associated with skipping breakfast of Korean children by analyzing the 24-hour recall intake data from the 2001 National Health and Nutrition Survey. The sample of this study consisted of 1,600 children aged 7 to 18 years. About 17% of the children skipped breakfast, consuming no food or beverage at all. About 30% of children reporting breakfast skipping in a self-administered survey were shown to have eaten some foods as a result of analysis of the 24-hour recall data. Students having eaten breakfast consumed 21% of Estimated Energy Requirement at breakfast. The multivariate logistic regression analyses showed that age was associated with skipping breakfast both in elementary and middle/high school students; older students were more likely to skip breakfast. Elementary school students from low-income families were more likely to skip breakfast than those from upper-high income families. Intervention programs are needed to prevent children from skipping breakfast by targeting older students. For elementary school students, such programs should be first developed for those from low-income families.

BACKGROUND/OBJECTIVES: Assessing changes in energy intake and dietary sources is important to understand trends in the prevalence of obesity. Thus, we examined trends in energy intake and its nutrient and food sources in Korean adults from 1998 through 2015. SUBJECTS/METHODS: This study included 70,769 subjects aged ${\geq}19$ years who completed a nutrition survey. Subject data were obtained from the 1998, 2001, 2005, 2007-2009, 2010-2012, and 2013-2015 Korea National Health and Nutrition Examination Surveys. Dietary intake was assessed by a 1-day 24-hour recall method. RESULTS: In men, the daily energy intake significantly increased from 2,196 kcal in 1998 to 2,489 kcal in 2013-2015 (P for trend < 0.0001). However, the daily energy intake among women did not change significantly over the same period (P for trend = 0.5772). The percentages of energy intake from animal foods (e.g., meat and milk) and beverages increased during the study period in both men and women. However, the percentage of energy intake from plant foods decreased due to a marked decrease in the intake of white rice. Changes in food sources of energy intake led to changes in the nutrient sources of energy intake; for example, the increase of energy intake from fat and decrease of energy intake from carbohydrate. CONCLUSIONS: This study suggests that since 1998, energy intake has increased among Korean adult men, but not among women. However, the composition of food and nutrient sources of energy intake has changed in both men and women. Energy intake and its nutrient and food sources should continue to be monitored regularly in the Korean adult population.

Objectives: The purpose of this study was to discover the changes in obesity prevalence and dietary habits in Korean adults residing in various residential areas during the last 10 years. Methods: Data on Korean adults aged 19 years and above was obtained from the 4th (2007-2009) and the 7th (2016-2018) Korea National Health and Nutrition Examination Survey. The subjects were classified into metropolitan (4th: n=5,977, 7th: n=6,651), urban (4th: n=4,511, 7th: n=5,512) and rural (4th: n=3,566, 7th: n=2,570) based on their residence. The general characteristics, nutrient intake, intake amount, food groups, and healthy dietary factors were analyzed. The association between residential areas and obesity prevalence were analyzed by multiple logistic regression. Results: In urban and rural areas, the obesity rate increased in the 7th survey compared to the 4th survey, excluding the metropolitan area. The carbohydrate intake decreased, and lipid intake increased in the 7th survey compared to the 4th survey. Over the same period, the intake of cereals and vegetables decreased, and the intake of meat and processed foods increased. Rural residents had a higher intake of cereals and vegetables, and a lower intake of milk and processed foods than those in metropolitan areas and urban residents. The proportion of subjects who practiced a healthy diet increased in the 7th survey compared to the 4th survey. In the 4th survey, there was no relationship seen between the prevalence of obesity and the subject's residential area, but in the 7th survey, the odds ratio of obesity was higher in rural areas than in the metropolitan areas, confirming the regional gap (OR: 1.16, 95% CI=1.00-1.36, P=0.044). Conclusions: This study showed that the obesity prevalence increased in rural residents compared to metropolitan residents, indicating a gap between the regions. The nutrient intake and intake of food groups changed in the 10 years under consideration, and there were differences seen between regions. Therefore, it is necessary to formulate a policy that will reduce obesity prevalence and health inequalities between regions.

The purpose of this study was to investigate the current status of chronic diseases according to obesity in the elderly older than age 65 using data from the 7th Korea National Health and Nutrition Examination Survey (2016~2018). The subjects of the survey were 3,245 elderly older than age 65 who participated in the health survey and nutrition survey, 45.8% of the subjects were males and 54.2% of the subjects were female. 37.5% of all the elderly were obese, and the females (42.4%) were more obese than the males (31.8%) (p<0.001). Diabetes, hypertension, and hypertriglyceridemia had a similar prevalence of 24.6%, 63.0%, and 12.7% in males and females, respectively. Hypercholesterolemia was higher in the elderly females (44.2%) than in the elderly males (24.9%) (p<0.001). Through the logistic regression analysis, it was found that the prevalence of chronic diseases was higher in obesity than normal in elderly males and females (p<0.001). The total food intake increased from 'under weight' to 'obesity' in males (p<0.01) and females (p<0.001). In the case of the elderly males, the higher the degree of obesity, the higher the energy intake (p<0.05), and 'pre-obesity' consumed the most energy in elderly females. As a result of this study, the higher the obesity rate of the elderly, the higher the prevalence of chronic diseases.

This study was conducted to examine the needs of nutrition education based on analysis of the eating habits and nutrition knowledge among middle school students. The survey was conducted on 536 students (boys=216, girls=320) using a questionnaire. The average number of meals consumed was three (67.5%) and 58.0% of students reported having breakfast. Concerning the nutritional knowledge, students showed the highest score (girls, 0.90${\pm}$0.03 and boys 0.82${\pm}$0.04) for items describing the proper diet plan for obesity. Additionally, nutritional knowledge was found to have a significant effect on dietary habits. Regarding the necessity for nutrition education, high response rates for "For normal growth of students (44.8%)" and "Help to select proper food and choose safe food (24.0%)" were observed. Taken together, these findings indicate that consistent and systematic management is required under the institutional support by the school to improve students' perception regarding nutrition and to develop effective nutrition education.
