Purpose: This study was conducted to evaluate nutrition intake and diet quality according to carbonated drink consumption in male adolescents (middle-school students = 480, high-school students = 417). Methods: We analyzed data from the combined 2007~2009 KNHANES (Korean National Health and Nutrition Examination Survey). Subjects were divided into two groups, the LCDI (low carbonated drink intake (< 1 time/week), n = 362) group and the HCDI (high carbonated drink intake (${\geq}1$ time/week), n = 535) group, according to carbonated beverage consumption. Nutrient and food group intake, NAR (nutrient adequacy ratio), and MAR (mean adequacy ratio) were analyzed using data from the 24-recall method. Results: Intake of plant protein, vitamin C, plant calcium, phosphorous, and potassium was significantly lower in the HCDI group, compared with the LCDI group. Percent of RNI (recommended nutrient intake) of vitamin C and phosphorous was significantly lower in the HCDI group, compared with the LCDI group. Percentage of subjects who consumed under EAR (estimated average requirement) of protein and vitamin C was significantly higher in the HCDI group, compared with the LCDI group. The NAR of phosphorous was significantly lower in the HCDI group, compared with the LCDI group. Food intakes from potato and starches, pulses and vegetables were significantly lower in the HCDI group, compared with the LCDI group. Conclusion: Consumption of carbonated drinks decreased the diet quality, including calcium, potassium, protein, and vitamin C. Therefore, nutrition education relating to consumption of carbonated drinks is required for male adolescents in order to maintain healthy dietary habits.

This study was performed to measure the liquid intake and the liquid intake difference by obesity, exercise frequency, and salty food intake score in female high school students. A total of 235 students in Daejeon area were participated, and the liquid intake was recorded for 3-days(2 weekdays and 1 weekend) by self-recording. The T-test, F-test, Pearson's correlation, and Scheffe test were exercised. The results of this study are as follows. The amount of total liquid intake was 838.5 ㎖/d. Among the 13 kinds of beverages, water was the highest 611.6 ㎖/d, 72.9% of liquid intake total, followed by carbonated drink(65.7 ㎖/d), milk(41.6 ㎖/d), fruit drink(32.8 ㎖/d), and fruit·vegetable juice(25.4 ㎖/d). The other beverages' intake were very small, ≤13.0 ㎖/d. Carbonated drink, milk, and coffee's intake were higher during weekend than weekday. There were sig. difference in water and total liquid intake by the obesity, student of BMI≥23.0 was higher than students of BMI<23.0. And only carbonated drink was sig. different by exercise frequency and salty food intake score. Exercise frequency of ≥3 d/week and salty food intake score of ≥7(very dangerous) consumed more carbonated drink than the lower counterparts. Total liquid intake of female high school students was not reach to 900 ㎖/d, the Adequate Intake in Dietary Reference Intake for Koreans 2015. The amount of milk intake was 41.6 ㎖/d, far less than the Recommended Intake of 2 serving, 400 ㎖/d. Education and promotion program may necessary to increase the liquid intake amount and to choose the nutritious beverage.

The purpose of this study was to investigate dietary habits, health lifestyle, preference and intake of beverages of Chinese students in Gyeonggi area. Therefore, we try to identify the factors that affect beverage consumption. According to the analysis of the demographic characteristics of male and female Chinese students, there were 155 male students (49.7%) and 157 female students (50.3%). There were statistically significant differences between the residence period and the time of coming to Korea according to sex (p<0.05), but there was no statistically significant difference between the education level, residence type and Korean ability (p>0.05). Analysis of the differences in health-related lifestyle among Chinese students of both sexes showed statistically significant difference in alcohol drinking, smoking, and exercise according to sex (p<0.05), but no statistically significant difference in computer use time (p>0.05). According to the analysis of the dietary habits of the Chinese students, there was a statistically significant difference in the number of meals per day, breakfast, lunch, dinner, snack frequency and number of midnight snacks, but no statistically significant difference in eating out frequency. As a result of the preference test for general beverages, 4.11 points of water, 3.81 points of milk, 3.64 points of fruit and vegetable juice, 3.58 points of tea, 3.25 points of coffee, 3.22 points of carbonated drinks, 2.92 points of functional drinks, respectively. Male students were more likely to prefer water, tea, and health functional drinks while female students had higher preference for fruit, vegetable juice and vinegar drinks (p<0.05). In general, consumption of regular drinks was 4.95 in water, 3.58 in milk, 3.03 in coffee, 2.92 in carbonated drink, 2.91 in fruit and vegetable juice, 2.63 in tea, 2.07 in functional drink, and 1.44 in vinegar appear. Male students had higher intake of water, tea, carbonated drinks, and health functional drinks while female students had higher intake of fruit and vegetable juice (p<0.05). The results of correlation analysis of factors affecting the general drinking of Chinese students are as follows. The intake of tea was related to the period of residence and dietary habits, the intake of milk for breakfast, the number of snacks and midnight snacks for carbonated drinks, and the fruit vegetable juice were related to dietary habits (p<0.01, p<0.05).

This study was performed to assess the effects of beverage consumption on nutrient intake and anthropometric measurements. Beverage intake and dietary intake were measured by a beverage frequency and quantity questionnaire and three 24-hour dietary recalls in 160 elementary school students in the Gyeongnam area. The number of drinking moments per month was 93.5 and drinking amount of all beverages was 626.6 mL per day. The amount of milk intake was 253.8 ml per day, which was the highest in all types of beverage consumption, followed by juice(133.6 mL), and carbonated beverage(77.7 mL). The amount of sweetened beverage which was defined as all beverages except milk and soy milk was 359.7 mL per day. Energy intakes from all kinds of beverages and sweetened beverages accounted for 20.3% and for 10.5% of the daily energy intake, respectively. The contributions of sweetened beverage intake to the daily energy intake in girls accounted for 13.5%, whereas in boys it was 7.7% and significantly lower. The number of drinking moments and the contribution of sweetened beverage intake to daily energy intake were negatively correlated with protein, vitamin A and niacin intake, respectively. The consumption of milk and soybean milk combined showed a significant negative correlation with the body fat ratio(%) and it also negatively correlated with waist-hip girth ratio(WHR). However, the sweetened beverage intake was not related any of the anthropometric measurement. In conclusion, consumption of the sweetened beverage dropped the nutritional quality of diet. However it was not related with anthropometric measurements in elementary students.

Along with recent economic prosperity, the consumption of commercially available beverages has increased dramatically. Beverages on the market are replacing tap water and constituting an increasing large proportion of the total daily fluoride intake. If such changes in the source of fluid intake are not taken into consideration, effective fluoride intake would become difficult in the fluoridated area while there would be confusion as to the basis for proper fluoride supplement prescription in the nonfluoridated area. So, dietary consultation is recommended for every pediatric patient. This study was conducted to provide the reference for dietary consultations on the subject of fluoride supplement using 72 beverages on the market. The fluoride content was measured and the fluoride intake from each age groups was calculated using fluoride ion specific electrode and HMDS-microdiffusion technique. 1. The average fluoride concentration of the 72 beverages was $0.23{\pm}0.10ppm$, from 0.0106ppm to 2.2050ppm. 2. Natural fruit juices, diluted fruit juices, carbonated beverages and mixed beverages showed average fluoride concentration of $0.15{\pm}0.66ppm$, $0.09{\pm}0.11ppm$, $0.15{\pm}0.23ppm$, $0.50{\pm}0.66ppm$, respectively. There were significant differrence between diluted friut juice drinks and mixed beverage, and between the carbonated beverages and mixed beverges(p<0.05). 3. Using available data on the daily total consumption of beverages and the relative consumption of beverages on the market according to age, daily fluoride intake for various age groups was calculated. According to the results, 2 to 3 year-old children need 0.13mgF/day, those between 4 and 6 year-old need 0.15mgF/day, and those between 7 and 10 year-old need 0.17mgF/day.

Objectives: This study was conducted to observe recent changes in adolescents' dietary behavior and indirectly evaluate the effects of the government's nutritional policies in Korea. Methods: We analyzed the secular trends in seven dietary behaviors using the Korea Youth Risk Behavior Web-based Survey data from 2005 to 2009. Through literature review, we included the policies implemented for the improvement of adolescents' dietary behaviors during the same periods. Results: The significant linear trends were observed in all dietary behaviors (p<0.05). Overall, all behaviors except the fruit intake rate were desirably changed during five years but undesirable changes were observed between 2008 and 2009 in all behaviors. Within those periods, several policies were implemented including 'Ban on carbonated-beverages in school', 'Green Food Zone', etc. Despite confirmed evidence of their effects, the policies on individual behavior such as nutrition education didn't influence the prevalence of dietary behaviors because they were conducted to too limited persons. Polices on the school environmental improvement, such as ban on carbonated beverage in school, were more effective because they decreased the exposure of undesirable food environment. However, for effect of Green Food Zone improving community environment we couldn't come to a conclusion because of too short period after full implementation. Conclusions: Among government nutrition policies conducted from 2005 to 2009, those on environmental improvement, especially in school, were more effective than those on individual behavior. Therefore, the development and implement of policies on school environmental improvement are needed in Korea.

This study was implemented to understand the motivation factors for $2^{nd}$ grade schoolchildren that effect on their preference for the sweet taste. The subjects included were 118 children (59 boys and 59 girls) and 118 children's guardians, from one elementary school. Children participated in sweet preference test and questionnaire survey with researcher's guidance provided in the school. Children's guardians were asked to fill out the questionnaire via home-letters. The results were as follows: 59% of the children preferred the cocoa beverage with the highest concentration of sugar among five cocoa beverages (0%, 2.5%, 5%, 7.5%, and 10% of sucrose/milk volume). The variables consisted of affective attitude, cognitive attitude, self-efficacy, parenting style, and sweets frequency. According to the analysis, sweet preferences were correlated with children's affective attitude (r=-0.207, p<0.01), self-efficacy (r=-0.288, p<0.01), frequency of drinking carbonated beverage (r=0.272, p<0.01), preference for yogurt (r=0.184, p<0.05), and preference for sweet bread (r=0.226, p<0.05). These results indicated that children can be more affected by affective attitude than cognitive attitude, and self-efficacy can be an important motivation factor to control the eating behavior related to sweets. Therefore, nutrition educators need to focus on developing various methods related to increasing self-efficacy for encouraging and motivating healthy eating behavior in children.

This study examined yearly trend of sugar-sweetened beverage(SSB) intake and compared nutritional status by SSB intake level in middle school students aged 12~14 years(n=2,543) using the data from 2007~2015 Korea National Health and Nutrition Examination Survey. SSB included carbonated drinks, sports drinks, and caffeinated drinks contained added sugar. Subjects were classified into three groups by SSB intake level obtained from 24-hour recall method: SSB 1(SSB intake 0 g/d), SSB 2(0 g/d < SSB intake < 50th percentile) and SSB 3(SSB intake ≥ 50th percentile). Result of daily intake of SSB was 76.1±6.2 g/d for boys and 59.5±4.7 g/d for girls and it was increased significantly for boys(p-trend 0.0004) and girls(p-trend 0.0038) by year. The most intakes were carbonated drinks followed by fruit juices and sports drinks for boys and girls. Percentage of daily intake compared to the dietary reference was increased for energy and iron while was decreased for calcium and vitamin C toward SSB 3 group. Ratio of excess intake of energy/fat was increased significantly for boys(p=0.0091) and girls(p<0.0001) toward SSB 3 group. Ratio of calcium deficiency was 86.8~94.9% for boys and girls and it was very high. Therefore, it should be emphasized to reduce SSB intake and drink plain water without added sugar, etc. and milk as a source of calcium for improving nutritional status of middle school students through dietary education and social support.

The purpose of this study was to survey several aspects of health and food related behavior of college students in Wonju area. Questionnaires were delivered personally to 430 students. The 37.9% of subjects were self-boarded and 27.4% lived in their home in Wonju area. They spend 230,000 won in average per month. Male students spent money more than female students and self-boarding students spent money more than other residental type students. The 90% of subjects thought they were healthy and the 25% of subjects exercised regularly. The subjects self-recognized their body as fat were more concerning about their weight control and had more weight control experience. SeIf-boarding students tended to skip their meals and had unbalanced diet. Students who lived in dormitory tended to skip meal less. Female students showed higher scores at balanced diet, snack intake, and left meal than male students. Self recognized their body as medium showed lower scores at overeating and eating irregularly. The amount of consumption of carbonated beverage was the highest among several instant foods. The frequencies of intake of those instant foods were different by gender, residental types, and eating behaviors.
