Objectives: The purpose of this study was to analyze the risk of dental caries and erosion associated with beverage consumption by measuring the sugar content and acidity of beverages for children, marketed in general food stores and cooperative living associations in Korea. Methods: Sixty types of children's beverages marketed in Korea were selected for the study. Calories, sodium, and carbohydrates in the nutrients per 100 ml, the sugar content, and pH of each beverage were measured. Frequency analysis, independent t-test, and one-way ANOVA were performed (p<0.05). Results: There was no significant difference in sugar content, calories, sodium, and carbohydrate content of regular and cooperative beverages, but the pH of cooperative beverages was significantly higher. Moreover, the mixed drinks had significantly lower sugar content, calories, and carbohydrates than fruit and juice, but the sodium content was significantly higher. Conclusions: When choosing beverages for children, caregivers should be able to easily access information about their impact on the child's oral health. Efforts should be made to maintain appropriate levels of sugar and acidity in beverages for children.

The caries activities of some commercially available children's beverages were measured to determine the risk of dental caries and provide basic data for preventing dental caries. For the experimental beverage, the beverages with the highest market share among carbonated beverages, fruit beverages, milk, and fermented milk products sold in the domestic market were selected. As a control, 0.25% glucose trypticase soy broth was prepared and used. The pH of the beverages, titrate acid and buffering capacity, and the acid production and vitality were measured over time after inoculating the beverages with Streptococcus mutans. The pH of children's beverages was the lowest in soda (2.61±0.02), and milk had the lowest in titratable acid (14.00±0.58). Fermented milk (80.33±3.64) had the highest buffering capacity, and carbonated beverage (9.40±1.06) had the lowest (P<0.05). Carbonated beverages (3 hr and 25 min) had the highest acid production, and milk (4 hr) had the lowest. In conclusion, thorough oral hygiene management is necessary after consuming children's beverages because they have a low pH promote high acid production of S. mutans.

Objectives: The study was conducted to investigate the relationship between several stress measures in everyday life, emotional eating behavior, and dietary pattern (snacks, fatty foods, sweet beverages, fruits and vegetables) in school-aged children. Methods: One hundred and ninety-four students of an elementary school located in Seongnam City participated in the study. The students responded to the survey questionnaire by self-report, which consisted of items regarding general characteristics, height, weight, dietary habits, frequency of consuming healthy (fruits and vegetables) and unhealthy foods (snacks, fatty foods, and sweet beverages), emotional eating behavior, and daily stress. Correlational analysis was performed to examine the relationship between stress, emotional eating behavior, and dietary pattern, and Poisson and logistic regression analyses were conducted to investigate the effects of stress on dietary pattern. Results: Positive correlations were found between all stress factors and emotional eating behavior and between the friend and personal factor (one of the stress factors) and the consumption of sweet beverages. The frequency of consuming sweet beverages was 2.6 times higher in the high stress group than in the low stress group (95% CI). Conclusions: Children's daily stress was associated with emotional eating behavior and undesirable dietary pattern such as consumption of sweet beverages.

The consumption of beverages among children is rising. The purpose of this study was to examine the effect of kid's drink on dental resin-based pit and fissure sealant. Pororo, I-kicker, Sunkist kids were included in the experimental groups, and Samdasu was included in the control group. A conventional dental sealant material ($Clinpro^{TM}Sealant^{(R)}$) was selected for this study. Resin specimens (8 mm in diameter and 1 mm in thickness) were prepared according to manufacturers' instructions and the initial roughness (Ra) was then measured. The pH of all the four groups was measured using a pH meter. The specimens were individually immersed in 5 ml of the experimental solutions and stored at $37^{\circ}C$ for 72 hours. Following this, the surface roughness of the resin specimens was measured by Surftest. The concentration of residual monomer released was determined by high performance liquid chromatography (HPLC). The surface morphology of the resin specimen was evaluated before and after storage by scanning electron microscopy (SEM). Data were statistically analyzed using Kruskal-Wallis and Duncan's test. The results showed that all the children's beverages examined in this study contained citric acid. The pH of I-kicker was the lowest ($3.03{\pm}0.01$), followed by that of Sunkist kids ($3.26{\pm}0.02$) and Pororo ($3.47{\pm}0.02$). We observed an increase in the surface roughness of resin specimens after 72 h of immersion in all the beverages tested (p<0.05). There was matrix degradation after immersion, visualized on SEM image, in all the beverage groups. Bisphenol-A-glycidyl methacrylate was not detected after 72 hours, but triethylene glycol dimethacrylate levels were increased in all the beverages tested during the 72 hours by HPLC. These results suggest that intake of beverages containing acid can cause degradation of the resin-based pit and fissure sealants in children.

Purpose: The purpose of this study was to identify factors associated with sugar-sweetened beverage consumption of Korean preschool children. Methods: Subjects for the study were recruited using the convenience sampling method. A total of 162 mothers with preschool children aged 3 to 5 years participated in the study using a self-reported questionnaire and provided data regarding the frequency and quantum of the children's sugar-sweetened beverage consumption days in a week and the factors associated with such consumption. Hierarchical multiple regression analysis was conducted to analyze the factors associated with the sugar-sweetened beverage consumption of preschool children. Results: Among the children-specific factors, age (β=.13, p=.015) was positively associated, while fruits/vegetable consumption (β=-.22, p<.001) was negatively associated with sugar-sweetened beverage consumption of the preschool children. Among the mother-specific factors, fruits/vegetable consumption of mothers was negatively associated (β=-.16, p=.006), while the sugar-sweetened beverage consumption of the mothers was positively associated with the sugar-sweetened beverage consumption of the preschool children (β=.27, p<.001). In addition, the maternal restrictive feeding style was negatively associated with sugar-sweetened beverage consumption of preschool children (β=-.23, p<.001). Conclusion: Based on these results, interventions targeted at children, parents, and the family environment should be developed to reduce the consumption of sugar-sweetened beverages in early childhood.

This research was performed to investigate mother's influence on their children's dietary life. We surveyed 312 elementary school students and their mothers in kyungpook province, and analyzed the responses using SAS 8.0 statistical program. The results showed that mothers' consuming behavior of processed foods was closely related to their children's dietary life. In detail, mother's preference, eating frequency, positive recognition on processed foods negatively affect on their children's dietary habit and snacking behavior. Also, the children whose mother has higher preference on processed foods showed significantly higher preference on cereals(p<0.05), fast foods(p<0.001), and carbonated beverages(p<0.001). Interestingly, mother's influence was stronger on children's eating frequency than preference of processed foods. The children whose mother has higher preference and eating frequency of processed foods ate significantly less vegetables(p<0.001), milk products(p<0.05), and more cereals(p<0.001), noodles(p<0.001), confectionary(p<0.001), fast foods(p<0.01), carbonated beverages(p<0.01). These results show that mothers' consuming behavior of processed foods significantly influences on their children's dietary life, which suggests the importance of mother's reasonable consuming attitude and behavior on dietary life. To promote children's healthy dietary life, therefore, the education programs for parent and children should be developed and practically used at school.

The purpose of this study was to observe the demineralization effects of children's range beverage on bovine enamel. 15 bovine teeth without dental caries were divided into 4 experimental groups (n=12) and control group (n=3). All samples immersed in beverages maintained 48 hours by $37^{\circ}C$ in incubate respectively. The surface microhardness values(${\Delta}VHN$) between before and after 48 hours treatment decreased and DIGNOdent value increased because enamel surface were corroded by experimentation beverage. Especially, there was statistical significantly difference in the carbonated drink. Morphological changes by scanning electron microscope were indicated that children's range beverage cause significant enamel demineralization effects on bovine tooth surface among five beverages.

The purpose of this study was to provide preliminary data for better safety control over children's preference foods sold in school stores. The survey was conducted from June to July 2009, to collect 749 types of children's preference foods sold in 150 middle and high school stores nation-wide excluding Jeju Island and general and nutrition information were analyzed. Out of 749 types of snack food items, 689 and 602 snacks were sold at high school and middle school stores respectively. Among children's preference foods, cookies, bread, and ice-cream were the main items. Among them, 98% of snacks were domestic products and the price range of each individual snacks were mostly between 600 and 900 won. 27.8% of children's preference foods sold were found to be in the high calorie/low nutrition food group. Even though the proportion of candy and fruit/vegetable beverages sold were not high, their proportion in high calorie/low nutrition snack group were higher than 68.1%. Among the children's preference foods sold in middle and high school stores, carbonated drinks and ramen were continuously sold in certain middle and high schools, even though sales were prohibited. This study concludes that government, corporations and retailers should work together in developing healthier children's snack distribution environment. In addition, dairy products, which take up 15% of children's preference food, should be diversified to meet their nutrient requirements.

Objectives: Screen time refers to the time spent using screen media, such as televisions, smartphones, computers, or tablets. Excessive exposure to screen media has been reported to negatively impact young children's health and development, including overweight, short sleep duration, and language delays. This study examined the association of screen time and mealtime media use with dietary behaviors among preschool children. Methods: A cross-sectional survey was conducted on parents of children aged three to five years using the online questionnaires of the Nutrition Quotient for Preschoolers (NQ-P) and the Dietary Screening Test (DST). Data from 261 children's parents were analyzed. Results: Of the 261 children, 96.9% used screen media, 55.6% used screen media for two hours or more daily, and 30.7% were exposed to screen media during meals. The NQ-P scores were significantly lower in the children with longer screen time and mealtime media use. Children who used screen media for two hours or more and those exposed to screen media during meals consumed kimchi less frequently and confectionery and sugar-sweetened beverages more frequently than children who used less than two hours and were not exposed to screen media during meals. In addition, they were more likely to be picky about food, refuse to eat, and less likely to feed themselves than children with shorter screen time and no mealtime media use. Conclusions: This study reported an association between unhealthy dietary behaviors, feeding difficulties, and screen time and mealtime media use among preschool children. Further research should explore effective strategies for reducing children's screen time.
