Nutritional quality evaluation of complementary baby food products in Korea according to food composition / 한국영양학회지

Purpose@#The purpose of this study was to evaluate the nutritional quality of complementary baby food products sold in Korea according to the baby food stages and food composition. @*Methods@#A total of 1,587 complementary food products sold online and offline between March and December 2021 were investigated. They ranged from liquid meals to solid rice for babies aged 5 to 36 months. @*Results@#The number of intakes per packaged volume was 2.8 in Stage 1, 1.9 in Stage 2, 1.4 in Stage 3, and 1.1 in Stage 4 (p < 0.0001). The dietary variety scores (DVS) of the complementary baby food products were 3.4 in Stage 1, 5.5 in Stage 2, 7.1 in Stage 3, and 9.7 in Stage 4 (p < 0.0001) and showed a significant increase in the later stages. The Korean dietary diversity score (KDDS) significantly increased from 2.3 in Stage 1, to 2.8 in Stage 2, 3.0 in Stage 3, and 3.4 in Stage 4 (p < 0.0001). The higher the baby food stage, the higher the proportion of grains/meat/vegetable ingredients. The ratio of protein intake to Adequate Intake (AI) or Recommended Nutrition Intake (RNI) was higher in products with a KDDS of 3 points or more, or in products with 2 points or fewer in Stages 1 and 2 (p < 0.0001, respectively). The ratio of protein intake to RNI increased as the KDDS score increased in Stages 3 and 4 (p < 0.0001, respectively). For all stages of baby foods, the ratio of protein intake to AI or RNI was high in products that included the meat group (beans, nuts, meat, eggs, fish, and shellfish) (p < 0.0001, respectively). @*Conclusion@#Continuous research and nutritional evaluation are required for establishing nutrient content standards for commercially available baby foods, considering breast milk intake.

The Association between Maternal Nutrition Knowledge, Dietary attitudes, and Dietary Behaviors Related to Sugar Intake, and Sugar Intake Reduction in Preschool Children

This study was undertaken to investigate the association between maternal nutrition knowledge, dietary attitudes, and behaviors related to sugar intake and sugar intake reduction in preschool children. Eighty-three children aged 5 to 6 years attending kindergartens in Hongseong and their mothers participated in this study from October 2020 to February 2021. The average age of the mothers was 38.7 years, and 53.0% of the children were male. As child age increased, nutrition knowledge of sugar intake reduction increased, but no relation was found between age and, dietary behavior and preference related to sugar intake reduction. For children whose mothers perceived that their child’s sugar preference was high, the behavioral score of sugar intake reduction was low. The more mothers allowed their children to eat sweet food; the higher was their child’s preference for sweet food, which was also significantly associated with an increased risk of high sugar intake. When mothers were provided education that encouraged reducing children’s sugar intakes, knowledge about reducing sugar intake in children was significantly increased. The study emphasizes the importance of the roles of mothers and primary caregivers regarding reducing the sugar intakes of preschool children.

Change of dietary habits and the use of home meal replacement and delivered foods due to COVID-19among college students in Chungcheong province, Korea / 한국영양학회지

Purpose@#The purpose of this study was to evaluate the change in the use of home meal replacement (HMR) and delivered foods and food habits of college students due to coronavirus disease 2019 (COVID-19). @*Methods@#A survey was conducted on 460 male and female college students in Chungcheong province in December 2020. @*Results@#The methods of participation in classes in the 2nd semester of 2020 were 40.2% for ‘100% non-face-to-face’ and 40.4% for ‘more than 70.0% of non-face-to-face classes’. 52.8% of the subjects responded that their physical activity had decreased, while 36.1% of the subjects responded that their body weight had increased over the past 6 months. Regarding the use of HMR, 62.7% of the male students and 69.6% of the female students responded with ‘1–2 times a week or less’ before the outbreak of COVID-19. After the outbreak, 57.4% of males and 46.7% of females responded with ‘3–4 times a week or more’ (p < 0.05, p < 0.001). As for the use of delivered food, 58.3% of the females responded with '2–3 times a month or less' before the outbreak, whereas the rate of responding with ‘1 or more times a week’ after the outbreak was 64.6% (p < 0.001). Negative changes in food habits caused by COVID-19 were in the order of irregular meals (56.7%), increased intake of delivered food (42.2%), increased intake of snacks (33.3%), and increased intake of processed foods such as HMR (30.4%). @*Conclusion@#As mentioned above, many college students had non-face-to-face classes due to COVID-19. During this period, they experienced decreased physical activity, weight gain, and undesirable eating habits such as irregular meal time, and increased intake of processed foods, delivery foods, and snacks. Therefore, there is a high need for nutrition education and policy support for the prevention and management of health and nutrition problems of college students, which can be caused due to the COVID-19 pandemic.

Status of serving labeling of home meal replacement-soups and stews, and evaluation of their energy and nutrient content per serving / 한국영양학회지

Purpose@#In this study, the serving size of home meal replacement (HMR)-soups (Guk, Tang) and stews (Jjigae) available in the Korean market was investigated, and an evaluation of the nutrition per serving was conducted based on the nutrition labeling. @*Methods@#The market research was conducted from March to August 2021 on products sold on the internet, convenience stores, supermarkets, and hypermarkets. A total of 370 products were investigated and classified into 3 types: Guk (n = 129), Tang (n = 132), and Jjigae (n = 109). @*Results@#An analysis of the survey revealed that 72.9% of Guk, 71.2% of Tang, and 79.8% of Jjigae had labels with servings per container, and 89.2% of Guk, 91.7% of Tang, and 99.1% of Jjigae had labels with nutrition facts. The nutritional evaluation per serving of Guk, Tang, and Jjigae was conducted for 259 products (87 Guk, 86 Tang, and 86 Jjigae) having labels containing both the servings per container and nutrition facts. The average serving size of Tang was 367.6 g, which was significantly higher than Guk (325.3 g) and Jjigae (305.1 g) (p < 0.001). The calorie content of Jjigae (171.4 kcal) and Tang (162.3 kcal) was significantly higher than Guk (90.8 kcal) (p < 0.001), and the protein content was the highest in Tang (16.3 g) (p < 0.001). The sodium content per serving of Jjigae (1,479.0 mg) was significantly higher than Guk (1,073.3 mg) and Tang (959.8 mg) (p < 0.001). The percent daily value per serving of all three types was less than 10% on average for calories and 15–30% for protein, whereas for sodium showed an average of around 50% (48–74%). @*Conclusion@#The serving size and nutritional value per serving of the HMR-soups and stews found in this study can be used as basic data to establish the reference serving size.

Study on Eating Habits and Dietary Quality according to Time Spent Using Smart Devices among Middle School Students in Incheon

The purpose of this study was to investigate the association between dietary quality and smart device use among middle school students. A total of 330 middle school students (171 boys and 159 girls) residing in Incheon participated in this questionnaire survey in June 2018. The boys and girls were divided into two groups according to their daily use time of smart devices: less than 3 hours a day (＜3 hours) and 3 hours or more a day (≥3 hours). Eating habits and dietary quality were assessed using a nutrition quotient for adolescents (NA-Q). For boys and girls, higher consumption frequency of white milk was significantly associated with less time spent using a smart device. For boys, a higher number of vegetable dishes and eating frequency of breakfast were significantly associated with the less time spent using a smart device. For girls, higher consumption frequency of processed beverages, ramyeon, and street foods was significantly associated with more time spent using a smart device. For boys and girls, those who spent more time using a smart device had significantly lower NA-Q scores, indicating low dietary quality. To sum up, more time spent using a smart device among middle school students may be associated with lower dietary quality. These results suggest the need to provide a nutrition education program and guidelines to students who use smart devices for a long time.

Status and needs of nutrition education for children's sugars intake reduction in elementary school / 한국영양학회지

PURPOSE: This study examined the status and needs of school-based nutritional education programs for reducing sugars intake in elementary schools. METHODS: A total of 230 elementary nutrition teachers participated in this study through an online survey in July 2017. RESULTS: Approximately one-third of the schools conducted nutrition education on reducing sugars intake as a main topic. The most frequent educated grade and education period were 4th and 3rd grade, and once a year. Most of the nutrition teachers answered that nutrition education related to reducing sugars intake for children was necessary. The nutrition teachers answered that first graders were the recipients in most need of nutrition education for reducing sugars but, realistically, third graders were the most suitable for nutrition education. The appropriate education topics were limited to the lower grades, such as sugars consumption related health problems, foods containing high sugars, and behaviors to reduce sugars intake; however, a wider variety of topics were selected for the upper grades. The experiment was considered to be an effective educational method for both the lower and upper grades. The most appropriate nutrition education media appeared to be a mock-up in the lower grades, and an experiment kit in the upper grades. Games and videos were highly considered to be effective media to educate students in reducing sugars consumption by voluntary participation in free time in the classroom in both the lower and upper grades. CONCLUSION: Nutrition education programs focusing on sugars intake reduction were conducted in some elementary schools, but the training time was short and the types of activities were limited. The perception and demand for nutrition education was very high. Therefore, the development and dissemination of elementary school-based nutritional education programs for sugars intake reduction is urgently needed. Moreover, to develop an effective nutrition education program, the education environment and demand in the field should be fully considered.

Evaluation of the meal variety with eating breakfast together as a family in Korean children: based on 2013 ~2015 Korean National Health and Nutrition Examination Survey / 한국영양학회지

PURPOSE: The aim of this study was to identify the nutritional status in Korean children eating breakfast together as a family or skipping breakfast from the 2013 ~ 2015 Korea National Health and Nutrition Examination Survey (KNHANES). METHODS: A total of 1,393 subjects (boys = 731, girls = 662), aged 6 ~ 11 years, were presented with a 24 hr-recall method, and classified according to their eating breakfast together as a family or skipping breakfast; and eating breakfast together as a family (EBF group; boys = 580, girls = 548), eating breakfast alone (EBA group; boys = 100, girls = 67), and skipping breakfast (SB group; boys = 51, girls = 47). RESULTS: In the boys, the SB group had a significantly lower carbohydrate (p = 0.0198) and vitamin C (p = 0.0219) density, and a higher fat (p = 0.0020) density than the EBF and EBA groups. In both boys and girls, the EBF and EBA groups showed a significantly larger number of dishes in breakfast than the SB group (p < 0.0001, respectively). In boys, the EBF group showed a significantly higher number of foods in breakfast than the EBA and SB groups (p < 0.0001). CONCLUSION: Children eating breakfast together as a family may be associated with a variety of food intake than children eating breakfast alone and skipping breakfast.

3-in-1 coffee consumption is associated with metabolic factors in adults: Based on 2012~2015 Korea National Health and Nutrition Examination Survey / 한국영양학회지

PURPOSE: This study was conducted to evaluate the risk of metabolic factors in adults consuming 3-in-1 coffee from the 2012~2015 Korea National Health and Nutrition Examination Survey (KNHANES). METHODS: A total of 5,872 subjects (male = 2,253, female = 3,619) aged 19~64 yrs were presented with food frequency questionnaires, and they were classified according to coffee consumption level and types of coffee consumed (black coffee, ≤1 time/day of 3-in-1 coffee, > 1 and ≤2 times/day of 3-in-1 coffee, > 2 times/day of 3-in-1 coffee). Analysis was conducted by gender for age-stratified groups: 19~39 (male = 968 and female = 1,285) and 40~64 (male = 1,468, female = 2,151) yrs old. RESULTS: Black coffee consumption was associated with a significantly higher education level and household income compared to 3-in-1 coffee consumption in both males and females. The > 2 times/day group had significantly more smokers compared to other patterns of coffee consumption in both males and females. In the 40~64 yrs age group, males and females in the > 2 times/day group had significantly lower density of micronutrients such as fiber, niacin, vitamin C, calcium, phosphorus,and potassium compared with black coffee consumption. In the 40~64 yrs age group, males (OR: 2.03, 95% CI: 1.13~3.64) in the > 2 times/day group were at a higher risk of metabolic syndrome compared with black coffee consumption after multivariable adjustment. CONCLUSION: We found that frequency of 3-in-1 coffee consumption may be associated with prevalence of metabolic syndrome in males aged 40~64 yrs.

Perception of sugar reduction, nutrition education, and frequency of snacking in children by the self-perceived sweet dietary habits of mothers in Busan

BACKGROUND/OBJECTIVES: The aim of this study was to investigate the perception of sugar reduction, nutrition education, and frequency of snacking in children according to the self-perceived dietary preferences for sweet taste by mothers in Busan. SUBJECTS/METHODS: A total of 277 mothers were surveyed, and their perceptions of sugar reduction and the frequency of snacking in children were assessed using a questionnaire. The subjects were classified into either a sweet (n = 91) or an unsweet (n = 186) group according to their self-perceived preferences for a sweet taste. RESULTS: In the sweet group, the results for sweet products were sweetened ice (86.8%), confectionery (74.7%), processed milk (73.6%), carbonated beverages (71.4%), and fermented milk (53.9%). In the unsweet group, the results were sweetened ice (88.7%), carbonated beverages (78.5%), processed milk (75.8%), confectionery (69.4%), and fermented milk (50.5%). The necessity of sugar intake reduction was high in both groups (sweet = 89.0%, unsweet = 82.8%). Beverage purchases after identifying the nutrition labeling was significantly lower in the sweet group than in the unsweet group (P < 0.05). The reasons for the beverage purchases instead of water were "habitually" (50.5%) and "like sweet taste" (25.3%) in the sweet group (P < 0.01). Snacking in children was significantly higher in the sweet group based on the increased frequencies of carbonated drinks (P < 0.01), fast food (P < 0.001), candy and chocolate (P < 0.05), crackers (P < 0.01), ramen (P < 0.01), and fish paste/hotdogs (P < 0.01). The frequency of purchase education after identifying the nutrition labeling was significantly lower in the sweet group than in the unsweet group (P < 0.01). CONCLUSIONS: These findings suggest that a perception of sugar reduction and practical nutrition education aimed at reducing the sugar intake are necessary to improve dietary habits.

Association of instant noodle intake with metabolic factors in Korea: Based on 2013~2014 Korean National Health and Nutrition Examination Survey / 한국영양학회지

PURPOSE: The aim of this study was to investigate the relationship between instant noodle intake and metabolic factors in Korean adults. METHODS: Study subjects were 5,894 (male 2,293, female 3,601) aged 19~64 years who participated in the 2013~2014 KNHANES. Information on frequency and consumption of instant noodles was obtained by the food frequency questionnaires method in KNHANES (Korean National Health and Nutrition Examination Survey), and subjects were classified according to age, sex, and instant noodle consumption (INC). RESULTS: The frequency and consumption of instant noodles was 1.2 times/week and 1.2 servings in subjects. High INC group (≥ 1 serving/week) was significantly younger in age compared with the low INC group (< 1 serving/week). However, the high INC group had significantly higher waist circumference, metabolic factors (triglyceride, cholesterol, and HDL-cholesterol), and dietary intake (energy intake, fat, and sodium density) compared with the low INC group. Hyperglycemia showed association with higher risk of highest quartile of INC after adjustments for multiple confounding factors, including age, gender, household income, education, smoking, and alcohol compared with the lowest quartile (OR: 1.4, 95% CI: 1.1-1.8). In female, abdominal obesity showed association with higher risk of highest quartile of INC after adjustments for multiple confounding factors compared with the lowest quartile (OR: 1.6, 95% CI: 1.2-2.2). CONCLUSION: Consumption of instant noodles was associated with increased prevalence of abdominal obesity and hyperglycemia in women. These findings suggest an association of instant noodle consumption status with metabolic risk

A Study on Sodium-related Dietary Attitude and Behaviors According to Sodium-related Nutrition Knowledge of University Students / 대한지역사회영양학회지

OBJECTIVES: Dietary life is closely associated with dietary attitude and diet-related knowledge. Particularly, dietary habit such as sodium intake can be affected by various dietary behaviors such as food choices, dietary attitude toward salty food and a preference for salty taste. The purpose of this study was to assess sodium-related nutrition knowledge and to identify sodium-related attitude and behaviors according to the level of sodium-related knowledge of university students. METHODS: Anthropometric measurements were provided by 408 students who participated in this study. The study participants answered questionnaires to provide information on general dietary behaviors, sodium-related dietary attitude and other behavioral factors. A total score of nutrition knowledge was used to categorize study participants in to two groups, namely, low level in sodium-related knowledge (LNaK) or high level in sodium-related knowledge (HNaK) and the attitude and the behaviors of students toward sodium intake were compared between these two groups. RESULTS: The ratio of female students in HNaK group was higher than that in the LNaK group. HNaK group had a higher score in checking nutrition label of processed food than the LNaK group. Total score of sodium-related attitude and behaviors of HNaK group were 34.81 and 32.75, respectively and these scores were significantly higher than that of the LNaK group whose scores were 32.57 and 30.57, respectively. Total energy intake was not different between two groups but the intakes of calcium, vitamin B2 and folate were higher in HNaK group than in the LNaK group. Correlation analysis adjusted for age and gender revealed that total score of sodium-related nutrition knowledge was positively correlated with total score of sodium-related attitude and behaviors. CONCLUSIONS: In conclusion, students who had high level of sodium-related nutrition knowledge had desirable attitude and behaviors toward sodium intake and these results can be considered in nutrition education for university students.

A Study on nutritional status and dietary quality according to carbonated drink consumption in male adolescents: Based on 2007~2009 Korean National Health and Nutrition Examination Survey / 한국영양학회지

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 ( or = 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.

The use Frequency and Amount of Food Sources of Sodium and Knowledge Requirement, and Job Satisfaction of Dietitians and Nutrition Teachers according to the School Types in Busan / 대한지역사회영양학회지

OBJECTIVES: To investigate the use frequency and amount of food sources of sodium and knowledge requirement, and job satisfaction with school food services according to the school types in Busan. METHODS: A total of 98 schools were surveyed and knowledge requirement and job satisfaction were assessed using a questionnaire. In addition, the use frequency and amount of food sources of sodium for 10 school days were examined. RESULTS: The response rate of the most difficult area among dietitians' tasks was significantly high in 'nutrition education and counseling' for elementary schools and 'hygiene management' for high schools (p < .05). The response rate of the factors to be considered in meal planning was significantly high in 'energy and nutrients requirement' for elementary schools and 'menu/taste preference of students' for middle and high schools (p < .05). The response rate of whether school food services affect health and eating habits of students or not was significant high in 'very helpful' for elementary schools (p < .001). The average sodium contents in the meals of elementary, middle and high schools was 1981.4 mg/meal/person/day, 1867.3 mg/meal/person/day and 1,329.9 mg/meal/person/day, respectively. For foods in highest sodium, Kimchi, Oribulgogi, and Kare rice were ranked 1st, 2nd and 3rd respectively. The main reason for not providing the fruits was 'price' among all groups. The knowledge requirement such as 'nutrition and menu management', 'nutrition education', and 'nutrition counseling' was significantly higher in elementary school compared with middle and high school (p < .001, p < .01, and p < .01 respectively). The dietitians and nutrition teachers of elementary schools have a higher job satisfaction compared with those of middle schools (p < .01). The job satisfaction was positively correlated with knowledge requirement of dietitians and nutrition teachers of elementary and middle schools. CONCLUSIONS: The results suggest that developing dietitians' education program about knowledge requirement contribute to increasing the school food service and job satisfaction in elementary and middle schools.

Dietary total sugar intake of Koreans: Based on the Korea National Health and Nutrition Examination Survey (KNHANES), 2008-2011 / 한국영양학회지

PURPOSE: The aim of this study is to estimate total sugar intake and identify major food sources of total sugar intake in the diet of the Korean population. METHODS: Dietary intake data of 33,745 subjects aged one year and over from the KNHANES 2008-2011 were used in the analysis. Information on dietary intake was obtained by one day 24-hour recall method in KNHANES. A database for total sugar content of foods reported in the KNHANES was established using Release 25 of the U.S. Department of Agriculture National Nutrient Database for Standard Reference, a total sugar database from the Ministry of Food and Drug Safety, and information from nutrition labeling of processed foods. With this database, total sugar intake of each subject was estimated from dietary intake data using SAS. RESULTS: Mean total sugar intake of Koreans was 61.4 g/person/day, corresponding to 12.8% of total daily energy intake. More than half of this amount (35.0 g/day, 7.1% of daily energy intake) was from processed foods. The top five processed food sources of total sugar intake for Koreans were granulated sugar, carbonated beverages, coffee, breads, and fruit and vegetable drinks. Compared to other age groups, total sugar intake of adolescents and young adults was much higher (12 to 18 yrs, 69.6 g/day and 19 to 29 yrs, 68.4 g/day) with higher beverage intake that beverage-driven sugar amounted up to 25% of total sugar intake. CONCLUSION: This study revealed that more elaborated and customized measures are needed for control of sugar intake of different subpopulation groups, even though current total sugar intake of Koreans was within the range (10-20% of daily energy intake) recommended by Dietary Reference Intakes for Koreans. In addition, development of a more reliable database on total sugar and added sugar content of foods commonly consumed by Koreans is warranted.

Prognostic Role of Interleukin-6, Interleukin-8, and Leptin Levels According to Breast Cancer Subtype / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: Inflammation within the tumor microenvironment has been reported to show an association with poor prognosis in breast cancer. However, the associations may differ according to breast cancer subtype. In this study, we investigated the association between inflammation-related markers and breast cancer recurrence according to patients' tumor subtypes. MATERIALS AND METHODS: This prospective study included 240 patients who underwent surgery for management of newly diagnosed breast cancer. Levels of inflammation-related markers (interleukin [IL]-1beta, IL-6, IL-8, monocyte chemoattractant protein-1 [MCP-1], leptin, and adiponectin) were measured at diagnosis, and the associations between these markers and breast cancer recurrence during a six-year follow-up period were examined using the Kaplan-Meier statistical method. RESULTS: Overall, inflammation-related markers showed no association with breast cancer recurrence. However, when data were stratified by tumor subtype, higher levels of some mediators showed an association with poor prognosis among patients with particular subtypes. Compared to patients without recurrence, patients with recurrence had higher levels of circulating IL-6 (p=0.024) and IL-8 (p=0.016) only among those with HER2- tumors and had higher levels of leptin (p=0.034) only among those with estrogen receptor (ER)+/progesterone receptor (PR)+ tumors. Results of survival analyses revealed an association of high levels of IL-6 (p=0.016) and IL-8 (p=0.022) with poor recurrence-free survival in patients with HER2- tumors. In addition, higher leptin levels indicated shorter recurrence-free survival time only among patients with ER+/PR+ tumors (p=0.022). CONCLUSION: We found that certain cytokines could have a differential prognostic impact on breast cancer recurrence according to breast cancer subtype. Conduct of additional large studies will be required in order to elucidate the precise roles of these cytokines in breast cancer progression.

Evaluation of nutrient intake and diet quality according to beverage consumption status of elementary school, middle school, and high school students: from the Korean National Health and Nutrition Examination Surveys, 2007-2008

The purpose of this study was to evaluate nutrition intake and diet quality according to beverage consumption status in elementary school students (ESS = 317), middle-school students (MSS = 431), and high-school students (HSS = 373). We analyzed data from the combined 2007-2008 Korean National Health and Nutrition Examination Survey (KNHANES). Subjects were divided into two groups, the non-beverage group and the beverage intake group according to beverage intake from drink types (fruit-vegetable drinks, carbonated drinks, and dairy drinks). Intake of dairy drinks was significantly lower in the carbonated drinks intake (CDI) group, compared with the non-CDI group in the MSS group. Intake of vitamin C was significantly higher in the fruit-vegetable drinks intake (FVDI) group, compared with the non-FVDI group. Intake of Ca and P was significantly lower in the CDI group, compared with the non-CDI group. Intake of vitamin B2, Ca, and P was significantly higher in the dairy drinks intake (DDI) group, compared with the non-DDI group. The mean adequacy ratio (MAR) of the FVDI group and the DDI group was significantly higher than those of the non-FVDI and non-DDI group. In diet quality, nutrients less than 1 on the index of nutritional quality (INQ) were significantly higher in the CDI group, compared with the non-CDI group. In conclusion, consumption of carbonated drinks dropped the diet quality however, consumption of fruit-vegetable drinks and dairy drinks improved the diet quality of micronutrients. Therefore, a well-planned diet must be used for replacement of nutrients lost from excessive intake of carbonated beverages during a time in life when growth is especially prominent.

Food Habits and Dietary Behavior Related to Using Processed Food among Male College Students Residing in Dormitory and Self-boarding in Gangwon / 대한지역사회영양학회지

The purpose of this study was to examine food habits and dietary behavior related to using processed food among male college students residing in dormitory and self-boarding in Gangwon. A total of 344 students (dormitory group: 227, self-boarding group: 117) were surveyed from May to June of 2012. The results are summarized as follows: self-boarding group had a significantly higher frequency of skipping breakfast and lunch and frequency of out meal compared with the dormitory group (p < 0.05, p < 0.05, p < 0.05 respectively). The self-boarding group had a significantly lower the score of 'eat vegetables and Kimchi at every meal' (p < 0.001) and 'eat a variety of food everyday' (p < 0.001) compared with the dormitory group. The self-boarding group had a significantly higher the preference for meat products (p < 0.05) and canned food (p < 0.01) for selecting processed food compared with the dormitory group. The consideration for selecting processed food was ranked by 'taste', 'price', 'expiration', 'appearance' and 'nutrition' in both dormitory and the self-boarding group. In the dormitory group, nutrition labels were identified certainly 2.6%, sometimes 12.8%, and rarely 17.2%. In the self-boarding group, nutrition labels were identified certainly 1.7%, sometimes 18.0%, and rarely 24.8%. The necessity of nutrition education was high in both dormitory group (51.6%) and the self-boarding group (62.4%). Therefore, development of an educational program and application of the information from nutrition labels for male college students, especially self-boarding students will be effective in improving dietary life in order to maintain healthy dietary habits.

A Study on Dietary Habits, Body Satisfaction and Nutritional Knowledge by Body Image of Middle School Girl Students in Chungbuk Area / 대한지역사회영양학회지

This study was performed to investigate the dietary habits, body satisfaction and nutritional knowledge according to body image of middle school girl students (n = 284). The subjects were classified as lean, normal and fat groups according to body image. The weight, body mass index (BMI) and the score of body image were significantly higher in the students who recognized their body image as 'fat'. The satisfaction of present body image was significantly lower in students who recognized their body image as 'lean'. The interest in weight control and experience of weight control were significantly higher in students who recognized their body image as 'fat'. The necessity of nutrition education was higher in all groups (lean 67.2%, normal 59.0% and fat 52.8%). The products used to feel sweetened were sweetened ice (68.7%), processed milk (68.3%), confectionery (62.3%), carbonated beverage (55.3%), fermented milk (38.0%) and none (6.0%). The frequency of consumption of fruit juices and fried food was significantly higher in 'normal' compared to 'fat'. There was no significant difference in the frequency of consumption of snack and nutritional knowledge among the three groups. In the multiple regression analysis, the score of body image was negatively associated with the frequency of snack consumption in the 'lean'. The score of body image was positively associated with identification of nutrition labels and an interest in weight control but was negatively associated with satisfaction of present body image in the 'fat'. Based on these results, we conclude that, the middle school girl students need correct recognition of body image and continuous and practical nutrition education in order to maintain healthy dietary habits.

The total sugar and free sugar content in beverages categorized according to recipes at coffee and beverage stores / 한국영양학회지

This study was designed to investigate the amount of free sugar according to each beverage category in coffee and beverage stores. The groups were categorized as 15 groups based on the kind of beverage material. The beverage groups contributing to total sugar per 100 mL were milk + syrup or powder, hot (12.9 g), ade (12.6 g), milk + syrup or powder + crushed ice (11.9 g), and espresso shot + milk + syrup + crushed ice (11.4 g). The beverage groups contributing to free sugar per 100 mL were ade (12.6 g), milk + syrup or powder + crushed ice (10.8 g), espresso shot + milk + syrup + crushed ice (10.3 g), and milk + syrup or powder, hot (9.7 g). The beverage groups contributing to total sugar (energy) per portion size were milk + syrup or powder + crushed ice 56.6 g (332.3 kcal), espresso shot + milk + syrup + crushed ice 49.3 g (333.4 kcal), milk + syrup or powder, hot 46.3 g (372.1 kcal), and milk + syrup or powder, ice 38.1 g (325.9 kcal). The beverage groups contributing to free sugar per portion size were milk + syrup or powder + crushed ice 51.2 g, espresso shot + milk + syrup + crushed ice 44.9 g, ade 37.1 g, milk + syrup or powder, hot 34.6 g, and milk + syrup or powder, ice 30.1 g. The percent of average free sugar per portion size of the WHO recommendation (free sugars <10% of total energy; <50 g/2,000 kcal) was milk + syrup or powder + crushed ice 102.4%, espresso shot + milk + syrup + crushed ice 89.8%, ade 74.1%, and milk + syrup or powder, hot 69.2%. The proportion of beverage in excess of WHO recommendation per portion size was 14.6% in espresso shot + milk + syrup + crushed ice, 22.7% in ade, and 10.9% in milk + syrup or powder, hot. Therefore, in coffee and beverage stores, menu development with reduced sugar content is needed, and nutrition information should be provided through sugar nutrition labeling.
