Objectives: The study was performed to investigate the relationship between snack intake and oral health behavior in middle school students in Gyeonggi-do area. Methods: The survey questionnaire was recorded by middle school students from July 6 to August 24, 2011. The questionnaire included items on general characteristics, snack intake status, and oral health behavior. Among collected survey questionnaire, a total of 620 questionnaires (320 males and 300 females) were analyzed using SPSS 15.0 program. Results: Frequencies of snack and beverage intakes were significantly higher in males than in females (p < 0.001). Oral health behavior was significantly higher in students with lower snack intake compared to those with higher or average snack intake (p < 0.05). Oral health behavior for tooth brushing and toothbrush care were significantly higher in females than in males (p < 0.05). Conclusions: Oral health behavior score that reflected better oral health of the subjects were higher as the snack intake was lower. Oral health behavior score was higher in females than in males. We conclude that the contents for oral health and nutrition education focused on snack intake need to be developed to induce changes in oral health behavior in middle school students.

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 < 0.01). The main reason, place and time of eating snacks were 'hunger' (79.2%), their home environment (50.9%) and 'after school hours' (89.7%). The favorite snack was 'ice cream' and, this snack habit was significantly different by gender of the child (p < 0.01) and TV watching time (p < 0.01). 'Milk and dairy products' scored highest (3.47) in snack intake frequency among longer-time TV viewers (> 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 ($R^2$) 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 ($R^2$= 0.108).

The objective of school lunch program is make a student to understand the basic knowledge on the diet through improved food patterns. Diet is an important factor in the development of dental caries. Generally, snack foods contain much sugar and cause dental caries to children. The diet education in the school lunch program should involve the control of snack food intake. In this study, the anlysis of influence of school lunch program on the cariogenic snack food intake of school children was carried out. The questionarie was given to 1,441 sixth-grade children of 5 school lunch group and 1,443 sixth-grade children of 5 non-school lunch group in Pusan on the intake of snack foods and toothbrushing after meals. Its were as follows : 1. No differences were observed snack food intake per day between school lunch group and non-school lunch group. 2. The snack food intake frequency at home in school lunch group was more frequent than that of non-school lunch group. However, in school, the result was reverse. 3. No difference was observed the frequency between school lunch group on the intake of cariogenic, foods, detergent foods, protective foods, cariogenic foods alone and cariogenic and detergent foods between meals. 4. The frequency of toothbrushing per day and the ratio of toothbrushing after meals in school lunch group was a little higher than that of non-school lunch group. 5. No difference was observed on the ratio of toothbrushing after snack food intake between school lunch group and non-school lunch group. 6. The influence of school lunch program on the cariogenic food intake in school children was little significant for its goodness. 7.

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.

In order to develop an obesity management program for teenagers, we compared obese and non-obese girls attending high schools in terms of their dietary practices related to snack consumption. Dietary records were collected for 7 days. No significant differences were found for the average daily energy intake between obese and non-obese girls. However, the highest energy intake was greater for obese girls while not much difference was found for the lowest amount of energy intake. Obese girls had significantly lower intakes in calcium (P < 0.01), vitamin A (P < 0.001) and folate (P < 0.01). Mean energy intake from snack ($594.1{\pm}312.1kcal$) was significantly higher for obese girls than for non-obese girls ($360.1{\pm}173.1kcal$) (P < 0.001). A significant, positive correlation was observed between energy intake from snack and total daily energy intake (r = 0.34 P < 0.01) only for obese girls. In case of dietary behaviors, obese adolescent girls consumed significantly greater number of items for snacks and fewer foods for regular meals compared to non-obese girls (P < 0.05). This study suggested that obesity management programs for adolescents should focus on providing strategies to reduce snack through enhancing balanced regular meals.

This study was carried out to survey dietary intakes of 739 elementary students, 4-6grades, in Won-Ju area, in 1998, to enhance the effect of school foodservice. The results were as follows : 1. Most investigated students had nuclear family with one brother or one sister. 2. The average height of boys and girls was $141.0{\pm}7.7cm\;and\;141.4{\pm}8.0cm$, and the average weight of them was $35.7{\pm}8.5kg\;and\;36.1{\pm}8.5kg$, respectively. There was no significant difference between boys and girls. 3. The rates of obesity were 12.2% in urban, 7.4% in rural and 0% in remote rural area by Rohrer index and 22.9% in urban 13.9% in rural and 0% in remote rural area by the rate based on standard weight. 4. All nutrients intake of investigated students were sufficient according to recommended dietary allowances. All nutrients intake of boys were higher than those of girls. Calcium intake of children with well educated mother was higher than that of children with poorly educated mother. Children in remote rural area had lower carbohydrate, calory and calcium intake than those in other areas. 5. Students without breakfast had lower protein and iron intake and higher calory from snack than those with breakfast. 6. Students who thought themselves to be obesity had low intake of carbohydrate, total calory and calory from snack and students with regular exercise had high intake of protein, iron, calcium and calory from snack. 7. Students with unbalanced diet, snack intake in large quantities and irregular meal had lower protein, fat, iron and calcium intake and higher calory from snack than other students. As a result, Students without breakfast often had lower all nutrients except calory from snack than other students, significantly. Problems of nutrients intake of elementary students in Won-Ju area were high rate of obesity, high intake of protein, unbalanced nutrients intake of students without meal or students with excessive eating and limited calcium intake of students with poorly educated mother.

The aim of this study was to provide descriptive information on meal and snack patterns and to investigate snacks in relation to energy intake and food choice according to the meal patterns of employed people in Korea. 683 employed people (292 males, 391 females) were interviewed to collect one day dietary data by using 24-h dietary recall. A recorded day was divided into 3 meal and 3 snack periods by the respondent's criteria and the time of consumption. To analyze the eating pattern participants were divided as the more frequent snack eaters (MFSE) and the less frequent snack eaters (LFSE). They were also categorized into 6 groups according to the frequency of all eating occasions. The common meal pattern in nearly half of the subjects (47.6%) was composed of three meals plus one or two snacks per day. A trend of an increasing the number of snacks in between main meals emerges, although the conventional meal pattern is still retained in most employed Korean adults. Women, aged 30-39, and urban residents, had a higher number of being MFSE than LFSE. Increasing eating occasions was associated with higher energy, protein, and carbohydrate intakes, with the exception of fat intakes. 16.8% of the total daily energy intake came from snack consumption, while the 3 main meals contributed 83.2%. Energy and macronutrient intakes from snacks in the MFSE were significantly higher than the LFSE. Instant coffee was the most popular snack in the morning and afternoon, whereas heavy snacks and alcohol were more frequently consumed by both of the meal skipper groups ($\leq$2M+2,3S and $\leq$2M+0,1S) in the evening. In conclusion, meal pattern is changing to reflect an increase of more snacks between the three main meals. Meal and snack patterns may be markers for the energy and macronutrient intakes of employed people in Korea.

We surveyed 553 middle school students living in Incheon using questionnaires to compare their food behaviors and snack intake patterns according to weight groups based on BMI. Mean BMI was 20.3 for males and 19.6 for females. The rate of underweight, normalweight and overweight students was 33.3, 51.7, and 15.0%, respectively. Compared to the other two groups, the overweight students perceived their body shape more accurately (p<0.01). Regarding the reasons for skipping dinner, the most frequent answer by the underweight students was 'because of snacks', while that of the overweight students was 'to lose weight' (p<0.01). The normalweight students were found to eat a Korean traditional type breakfast more frequently than the other weight groups (p<0.05). The overweight female group was more likely to overeathabitually, whereas the normalweight and underweight groups tended to overeat when they were under stress (p<0.05). As for the amount of the snack intake, the overweight male students replied that they eat quite a lot of snacks. As a conclusion, the problems found in the underweight group were unbalanced diet and the disturbance of regular meal patterns due to inappropriate snack intake. The problems shown in the overweight group were overeating due to habit or stress, fast eating speed and large amount of snack intake.
