  • BACKGROUND/OBJECTIVES: Eating out has been reported to have negative effects on nutritional status. However, eating out can include meals prepared at home and eaten outside. Conversely, meals eaten at home can be brought from outside, as take-out and home deliveries have become common in Korea. Thus, we tested whether or not meal preparation location influences daily diet quality. SUBJECTS/METHODS: From the Korea National Health and Nutrition Examination Survey (KNHANES) 2007-2009, 4,915 Korean adults (20-64 years) were classified into two groups: home-made meal group (HMG), who ate ${\geq}2$ meals per day prepared at home (n = 4,146), and non-home-made meal group (NHMG), who ate ${\geq}2$ meals per day prepared outside home (n = 769). Daily diet quality was determined by energy intake, nutrient intake, Dietary Variety Score (DVS), and Diet Diversity Score (DDS). RESULTS: Compared to the HMG, the NHMG was more likely to consist of men, single, employed, educated and of a higher economic status (all, P < 0.01). The NHMG showed higher energy intakes (1,776 vs. 2,116 kcal/day) with higher percentages of energy from protein (15 vs. 23%) and fat (14 vs. 16%) and lower intakes of dietary fiber, phosphorus, potassium, niacin, and vitamin C (all, P < 0.01) than the HMG, with some variations among age groups. The NHMG tended to consume foods prepared by frying and grilling and had more one-dish meals such as bibimbap, noodles, and dumplings but also showed higher dietary diversity. CONCLUSIONS: It should be noted that home-made meals do not necessarily guarantee a healthy diet, and the effects of meal preparation location on nutritional status might vary depending on socio-demographic characteristics.

  • This study was conducted to investigate the association of nutrients intake with sugar-containing food consumption of elementary school students in Daegu-Kyungpook area. We analyzed the dietary information from 164 elementary school students (82 boys, 82 girls) participated in "Dietary Intake Survey of Infants, Children and Adolescents" conducted by Korea Food & Drug Administration and Korea Health Industry Development Institute. Information on habitual dietary intake of sugar-containing foods was collected by food frequency questionnaires. Daily nutrients intake of each subject was calculated from 24-hour recall data for two non-consecutive days. As a result of average daily intake of major foods of elementary school students was analyzed from 1 to 50 ranking that show up higher ranking of white milk and white rice but include many kind of sugar-containing food. Dietary intake of energy, carbohydrate, Ca, P, Fe and riboflavin were significantly lower for girls with higher sugar-containing food frequency scores. Significantly negative associations between Index of Nutrition Quality (INQ) and sugar-containing food frequency scores were observed for calcium (r = -0.34) and iron (r = -0.32) among girls. Mean Adequacy Ratio (MAR) was significantly lower for girls with higher sugar-containing food frequency scores (r = -0.26). Our results indicated that nutrition education for elementary school students should focus on the importance of reducing the sugarcontaining food consumption with more attention for girls.

  • During last few decades dietary guidelines for the weight management mainly have focused on a low-fat, high carbohydrate diet. Carbohydrate was supposed to be low-dense, highly satiating as well as it affects little on the lipogenesis. Although low-fat diet has significant weight-reducing effect, the loss was modest and usually regained after cessation of the diet. Furthermore, low-fat, modest-carbohydrate diet did not impact on the ever increasing rates of overweight and obesity. Alternative approaches include low-carbohydrate diet, high-carbohydrate diet and low-glycemic index diet. Although none of above mentioned diet have sufficient evidence for standard weight management diet, short-term efficacy and safety are being approved continuously. Low-carbohydrate diet contains less than 45% of carbohydrate in daily energy consumption, it is claimed to have more satiating effect and to improve metabolism. However, low compliance due to the limitation of food choice should be considered on prescribing the diet. High-carbohydrate which contains 90% of carbohydrate in total daily energy consumption, is effective in providing satiety and lowering total calorie intake and cholesterol. On the other hand, nutritional unbalance should be took into account. Low-glycemic index diet is based on the theory that contemporary diet contains significantly less fiber and unrefined carbohydrate, therefore insulin secretion is disturbed. Because low glycemic index food slowly increase blood glucose and insulin level, it induces much satiating effect and may decrease calorie ultimate intake. However, poor standardization of glycemic index is one of the main obstacle for the diet to be applied in the clinic. Meanwhile, high fructose food and beverage should be discouraged because it has little satiating effect and may cause insulin resistance. High fiber food is another recommendation for healthy, lean diet.

  • In order to know contents of vitamin B$_{12}$ in the fermented foods in Korea, the contents of this vitamin are studied on the following foods; kimchies (pickled vegetables) .................. 39 chukkals (fermented and salted sea foods) ...... 8 fermented soy-bean products .................... 5 the kimchies and fermented soybean products studied in this paper, are from individual homes and chukkals are from markets. The content of vitamin B$_{12}$ is estimated by the microbiological assay method using lactobacillus leichmannii ATCC 7830. Details for assay are indicated in the original part of this paper. The pseudo-vitamin B$_{12}$ substances as thymidine which is active to the growth of lactobacillus leichmannii, are eliminated by the alkali treatment method of sample solution. According to the results as indicated in the table, the following conclusions are summerized; 1. Vitamin B$_{12}$ contents of kimchies for winter season are 1.03 to 1.52 mcg% in average. The hobakk-kimchi which contain the highest content of vitamin B$_{12}$ is not popular one among Korean. 2. Chukkals contain much higher content of vitamin B$_{12}$ varying from 0.91 to 11.10mcg%. 3. The soybean fermented foods, as kanjang, denjang, kochojang, contain lower content of vitamine B$_{12}$ varying from 0.08 to 0.52 mcg% containing higher content of pseudo-vitamin. 4. Based on daily consumption of kimchi in winter season by Chai, the consumption of this vitamin through kimchi is about 3 mcgs daily per capita. This will be a quite source of this vitamin for Korean as vitamin C. as vitamin C.

  • There is growing evidence that substance use such as tobacco or alcohol consumption influences health disparity among adolescents. Previous research papers have shown an inconsistency in the relationship between socio-economic status (SES) and substance use in adolescents. However, little is known about socio-economic differences in unhealthy behaviors among Korean adolescents. The purpose of the present study is to explore associations between SES and substance use in Korean adolescents. The analysis was performed using data from the 2009 Korean Youth Risk Behavior Web-based Survey (YRBS), which included a nationally representative sample of middle and high school students. Drinking/heavy drinking and smoking/daily smoking behavior indices were used for dependent variables, and perceived economic status, family affluence score, parents' education were used for independent variables. Chi-square test were used to compare tobacco and alcohol consumption among 3 SES groups. Logistic regression models were used to identify statistically significant socio-economic factors after adjusting other covariates. Higher perceived economic status and higher family affluence were associated with higher rates of smoking, daily smoking, drinking, and heavy drinking, while lower level of parents' education was related to higher use of tobacco and alcohol. Socio-economic status significantly influences health behaviors in adolescents, and it may consequently affect health disparity in their adulthood. Therefore, there is a need of continuous monitoring and follow-up research of health disparity among adolescents.

  • Purpose: Smoking among adolescents is a critical healthcare concern that needs to be tackled with respect to not only intrapersonal and interpersonal factors but also socio-cultural factors. This study was to identify the smoking behaviors and amount of tobacco consumption among adolescents, and to investigate the factors associated with the behaviors and amount. Methods: A cross-sectional study was conducted based on the theory of triadic influence using a nationally representative secondary data set, the 2018 Korea Youth Risk Behavior Survey (N=60,040). The analysis was performed by dividing smoking behaviors into lifetime, current, and daily smoking, and smoking amount into light, moderate, and heavy smoking. Descriptive statistics and multinomial logistic regression analyses were conducted. Results: Overall, 8.2%, 3.2% and 3.4% of the adolescents were involved in lifetime, current, and daily smoking, respectively. In addition, 5.3%, 0.8%, and 0.6% of the adolescents were involved in light, moderate, and heavy smoking, respectively. The factor associated with smoking behaviors and the amount of tobacco consumed were gender, academic achievement, depression, living with family, close friend's smoking, violent victimization, household economic status, and school level (all ps<.05). Conclusion: A considerable number of adolescents are engaged in risky smoking behaviors and consume large amounts of tobacco. Adolescents who said yes to peer smoking, violent victimization, not living with their family, and depressive emotions were more likely to engage in risky smoking behaviors and consume large amounts of tobacco. Tailored interventions to decrease smoking should be planed and provided, while considering the school and home environment and individual needs of adolescents.

  • Objectives: This study was undertaken to compare dietary life of the elderly living alone and in a family, and to compare differences based on gender, for the 2013-2016 Korea National Health and Nutrition Examination Survey (KNHANES). Methods: The subjects included 2,612 elderly people aged over 65 years who participated in the health survey, health examination and nutrition survey. Subjects on a diet therapy were excluded. This study analyzed the general characteristics, dietary habits, daily energy and nutrient intakes, CPF ratio, estimated average requirement (EAR), nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR), index of nutrient quality (INQ), and food consumption of the elderly living alone and in a family. We also compared the differences based on gender. Results: Daily intake of food, water, dietary fiber, potassium, retinol, and riboflavin were low in the male elderly subjects living alone. The elderly living with family revealed higher NAR and MAR as compared to the elderly living alone. Although all MAR values were <1, the elderly living alone had lower values. Considering the intake of food, the consumption of seaweed, fish and shellfish, and oils (animal) was higher in elderly men living with families, whereas women living with families consumed more vegetables, fruits, seaweeds and seafood, as compared to their counterparts living alone. Furthermore, analyzing the foods consumed by the elderly people living alone, female subjects consumed more seaweed, milk and animal oil as compared to male subjects. Conclusions: The results of this study indicate that the elderly living alone have poor nutrient intake as compared to the elderly living with families. Based on this research data, we recommend that it is necessary to improve the health and nutritional status of the elderly living alone.

  • Purpose: The purpose of this study was to evaluate the effectiveness of a health promotion program utilizing action planning strategy for young adults. Methods: A non-equivalent control group pre-post-test design was used. One hundred three university students participated in the study. Participants in the experimental group (n=51) were provided the health promotion program utilizing action planning strategy for five weeks. The program consisted of weekly sessions that included action planning and group feedback. The control group (n=52) was provided with health information every week for 5 weeks. Program outcomes, including self-efficacy, physical activity health behaviors, total exercise time per week, daily cigarette consumption, frequency of alcohol drinking per month, nutritional health behaviors, and subjective health status, were assessed at baseline and at follow-up after 5 weeks. Results: The participants in the experimental group demonstrated significant increases in self-efficacy, physical activity health behaviors, weekly exercise time, and nutritional health behaviors and significant decreases in daily cigarette consumption than those in the control group. Conclusion: The health promotion program utilizing action planning strategy is a brief and effective intervention to promote health behaviors among young adults. Further investigation is warranted to assess the program's effectiveness among other age groups and populations at high risk for chronic illness.

  • The objective of this study was to assess the association of changes in behaviors and depressed mood during the COVID-19 pandemic in Korea. A cross-sectional internet-based survey was conducted, using proportional samples of Korean adults and a logistic regression model was used to assess the association. As a result, negative changes of daily sitting or lying down time, daily walking time, smoking, and alcohol consumption were associated with being more depressed during the COVID-19 pandemic [odds ratios (ORs): 2.23 (95% CI=1.77-2.81), 2.04 (95% CI=1.63-2.56), 2.84 (95% CI=1.51-5.36), and 1.82 (95% CI=1.26-2.63), respectively]. This indicates that strategies to promote positive health behaviors change (increased activities and decreased consumption of smoking and alcohol) could help address psychological distress during the COVID-19 pandemic.

  • In the present study, exposure to heavy metals by consumption of edible seaweeds (green laver, laver, hijiki, sea tangle, and sea mustard) was assessed based on their concentrations of lead (Pb), cadmium (Cd), arsenic (As), and mercury (Hg). The mean of heavy metal concentrations were 0.006-0.023 mg/kg for Pb, 0.037-0.156 mg/kg for Cd, 1.117-15.928 mg/kg for As, and 0.008-0.021 mg/kg for Hg. In multivariate analysis, the correlations were high between Pb levels in sea mustard, Cb levels in laver, and As and Hg level in Hijiki. However, the estimated daily intake and target hazard quotient (THQ) of the heavy metals in edible seaweeds were below their approved limits suggesting no health risks associated with seaweed consumption by Koreans.
