The objective of this study was to investigate difference in the diet by the kind of meal and the economic status. Nutrient contents at each meals were compared and differences in food intake at different meal were analyzed by economic status. Data from the 1998 Korean National Health Examination Nutrition Survey were used. Using the poverty line based on the 1998 Korean minimum cost of living, the subjects (n = 10400) were classified into high class (36.1％), middle class (40.7％) and low class (23.1 ％). Most nutrient intakes were obtained for main meals regardless of economic status. For high class, breakfast, lunch, dinner and snacks bring about 21, 29, 30 and 19 ％ of total energy intake, for middle class 22, 29, 30 and 19％ and for low class 24, 30, 30 and 16％, respectively. The high-middle class people tend to get more food intakes and nutrients at dinner and snacks, while the low class at main meals. This result was associated with the consumption of a smaller number of meals and a greater number of snacks daily as the economic level was going up (p 〈 0.05). Meals contributed to energy, protein and fat intake, and snacks to water, retinol and vitamin C. The food intakes by food group were different at meals by economic class. Seaweed product were popular breakfast foods in both middle and low groups. Thus three meals such as breakfast, lunch and dinner still delivered most of the energy and most of the macro-nutrients regardless of economic status.

Objectives: This study was to examine the association of sugar-containing snacking habits with dental caries and periodontal diseases. Methods: This study was conducted on 2,807 adults who answered both oral examination and food intake frequency survey in the data of 2015 Korea National Health and Nutrition Examination Survey. The intake frequency of sugary snacks was selected from 17 kind of snacks, which had high sugar content and could affect oral disease. We used the complex sample logistic regression using SPSS 23.0 confirmed the correlation of sugary snack intake frequency and oral diseases. Results: 16.9% of all adults had a sugary snack at least three times a day. 20.7% of dental caries patients and 25.8% of people with periodontal diseases consumed sugary snacks more than three times a day. Especially, periodontal diseases were 1.51 times higher(p=0.008) in three or more consuming snacks group than that who ingested sugary snacks less than six times a week, by correcting the general characteristics and oral health behaviors. Conclusions: Oral health in adults affects oral health in old age, so from a public health perspective, integrated intervention is required to manage the self-cultivation health and to create correct eating habits.

The purpose of this study was to investigate the consumption and perception of high caloric-low nutrient dense foods in middle school students in the Daegu. Among 550 questionnaires distributed to students in Daegu, 528 (256 boys and 272 girls) were analyzed. A little higher than 80% of students ate snacks everyday, and 43.4%, 29.0%, and 8.1% ate snacks once, twice, and three times or more per day, respectively. Snacks and foods most frequently consumed were ice cream, fried noodles, drinks, cookies, and baked goods. Energy supply from snacks was 104.8~356.9 Kcal/intake while that from meal substitution foods was 520.7~980 Kcal/intake. Students' knowledge score of high caloric-low nutrient dense foods was $6.51{\pm}3.02$ out of 10 points. Sixty percent of students did not read nutrition labels, but 67.9% of them thought that they need nutrition education by nutrition teachers. Students recognized the criteria of high caloric-low nutrient dense foods as well as proper food selection for essential educational items, It was concluded that effective education should be implemented in middle schools by nutrition teachers for students to develop good habits in selecting snacks and foods.

This study was conducted to evaluate children's purchase behavior (frequency of snack consumption and purchase) and preference for high protein snack products developed for weight control and nutritional balance. A total of 80 elementary school students (from the 3rd to 6th graders) in the Gyeonggi-do learning center were participated and 76 were used for the analysis. The most common response for liking snacks was taste (71.4%), and the most preferred types of snacks were chips (42.1%) and puff snacks (34.2%). The highest frequency of snack ingestion was 1-3 times per week (48; 63.2%), and the main purchasers were parents (65.8%). Cheese, corn and chili flavors were more preferred than the control, while yogurt taste was slightly less preferred than the control. The results of this study showed the possibility of commercialization of new protein snacks according to children's seasoning preference and provide the insights into the snack preferences of children as main consumers.

In this study, sixth grade school children in the Guri area were surveyed via questionnaire regarding their sociodemographic characteristics, snacking patterns, and intakes of different food groups and sugared snacks. Students with employed mothers had more frequent snacking events and were more dependent on store-purchased snacks compared to those having an unemployed mother. A high consumption of snack sugar was associated with a higher dietary diversity score. There was a positive relationship between snack sugar intake and the intakes of meat and dairy products and foods in the oil and nut group, respectively. A high snack sugar intake had a negative effect on fruit intake. Specific nutrient intake data will be required before conclusions can be made on whether nutrient imbalances are a concern in elementary school children having sweet snacks. Yet, the current data indicate that an increased snack sugar intake can decrease fruit intake, which could result in certain nutrient deficits. Specific dietary guidance may be necessary to address the snacking habits of elementary school children.

Stress has been known to change dietary behaviors and food intakes in individuals. The purpose of this study was to investigate the effect of stress level on the frequency and the amount of snack consumption. The high stress group (HS) showed significantly higher frequency of consumption for bread, chips, cookies, ramyeon, and frozen snacks (p<0.05) compared to low stress group (LS) with higher frequency of snack consumption (p<0.01), and increased intakes of energy, carbohydrates, and sodium from snacks (p<0.01) than LS. As the stress level became higher, the proportions of students with irregular meals, overeating, and night snacking increased (p<0.01). Also, 33.0% of the subjects answered that they consumed an increased amount of snacks when they were feeling stressed. Our results indicated that stress has negative influence on snack consumption in middle school girls.
