Objectives: This study investigated the relationship between obesity and dental caries of Korean adolescents. Methods: Data from the Korea National Health and Nutrition Examination Survey (KNHNES VI) (2013 to 2015) were used and targeted adolescents aged 13 to 18 years. For statistical analysis, the SPSS 18.0 program was used, and the significance level was set at 0.05. Results: For the general and health-related characteristics, female students (p=0.001) showed higher decayed, missing, and filled teeth (DMFT) index than male students. Furthermore, DMFT showed higher tendency, as age was higher (p<0.001). Smoking (p=0.011) and drinking experience (p=0.027) revealed higher DMFT. The dental caries experience was significantly different among students who were female (p=0.033), older (p=0.001), and overweight or underweight (p=0.022). In the BMI for the general and health-related characteristics, male students had higher obesity rate than female students (p=0.003), and obese subjects had higher dental checkup in the last year (p=0.013). In multiple linear regression analysis of obesity and DMFT, the unadjusted model showed that the obesity group's DMFT was about 0.8 higher than that of the normal group (p=0.024). However, statistical significance was not shown in the adjusted models. In the logistic regression analysis of obesity and dental caries experience, the unadjusted model 1 (1.93 times), the adjusted model 2 (1.79 times), and model 3 (1.76 times) showed significantly higher dental caries experience. Conclusions: Both obesity and dental caries are related to diet habits and lifestyles and have a negative impact on adult health. Therefore, it is necessary to create a healthy social environment around the adolescent, and proper intervention through education is required to form healthy habits.

The aim of this study was to compare nutrient intakes, dietary habits, and blood components of smokers with non-smokers in the Seoul area and its vicinity. The results showed that non-smokers had higher intakes of brown rice, grains, fruit, vegetable and kimchi than the smokers. Smokers consumed more protein (p<0.001), vitamin B1 (p<0.001), vitamin B2 (p<0.007), niacin (p<0.0001), zinc (p<0.031) and phosphorus (p<0.005) than did non-smokers, whereas non-smokers' intakes of vitamin A (p<0.037), and folic acid (p<0.043) was higher than that of smokers. Individuals who smoked tended to have significantly higher levels of hemoglobin and monocytes. There were no significant differences by smoking status for dihydrolipoic acid (DHLA), arachidonic acid (AA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which were in normal ranges. No significant differences by smoking status were shown for plasma homocysteine, HDL-cholesterol, LDL-cholesterol, vitamin C, and vitamin A. In conclusion, because smokers maintain a less healthy diet and life-style, it is to be recommended that educational programs be developed for smokers, guiding them into adopting better dietary habits in order to maintain and improve their health.

This study was carried out to investigate the eating behaviors and the preferences of industrial workers in Korea. This survey was conducted from May 20 to June 20, 1998 by constructed questionnaires and the subjects were 364 males and 588 females. The results obtained were summarized as follows: 1) The subjects who didn't have breakfast regularly were 41.7% because they didn't have enough time to eat. The main type of breakfast were cooked rice. 2) The subjects who used the company cafeteria were 60.5% and men used the company cafeteria more than women. The most favorite side dishes by the subjects were roasted foods and next side dishes were seasoned foods. There were not significantly different the kinds of favorite side dishes between men and women. The main reason that the subjects preferred to a specific side dish was 'delicious'. 3) Foods and dishes that the subjects could approached frequently and easily made the eating habits changed. The most favorite meal types of the subjects were Korean foods because those were good taste for the subjects. The favorite snacks by men were ramyon and those by women were rolled rice(Gimbab). 4) The pan-fried foods(Jun) were the most favorite food in the cloudy day and the salads were the most favorite food in the sunny day. The most favorite taste of the subjects were light and clear tastes and next favorite taste of the subjects was salty tastes. This study shows that the eating habit of industrial workers could be changed by easily and frequently approached food and weather. In addition, the lacks of time was main reason that the subjects couldn't have regular breakfast. Therefore, it needs to develop the desirable programs and diet menus to consider the situation of the industrial workers and weather.

The present study was conducted to evaluate nutrient intakes of industrial workers with hyperlipidemia and cholesterol-saturated fat indices(CSI) of their daily meals and various side dishes accompanied with alcohol. Thirty eight male subjects of 41.0$\pm$6.5 years whose average serum cholesterol and triglyceride levels were 222.9$\pm$37.7 and 282.3$\pm$139.3mg/이 were interviewed on daily intakes of foods and drinking habits including types and amounts of side dishes using 24-hour recall and questionnaire methods. Average energy habits including twenty six non-drinkers and twelve drinkers were 2365$\pm$41 and 2822$\pm$417kcal, respectively but intakes of other nutrients were not very different between two groups. Carotene intakes was, however, low in drinkers. Intakes of saturated fat, cholesterol and CSI of subjects' daily meals were 15.4$\pm$5.4g, 229$\pm$114mg and 27.1$\pm$10.4 for non-drinkers and 18.7$\pm$7.8g, 238$\pm$69mg and 30.8$\pm$9.8 for drinkers. CSI of their daily meals varied from 10 to 60 without much differences in energy values and were positively correlated with serum cholesterol levels(r=0.2606, p<0.05). Average alcohol intakes obtained from subjects' drinking habit was 89.5$\pm$46.8g per day and major side dish was roasted beef giving 660$\pm$234kcal of energy and 24.3$\pm$8.0 of CSI. From the present study, it is concluded that industrial workers are more prone to have hyperlipidemic diets due to alcohol. To improve their diet and health, an appropriate nutrition education should be necessary and CSI of various Korean foods and meals can be used as handy self-control education tool.

BACKGROUND/OBJECTIVES: Nutrition knowledge has been reported to have a weak positive effect on healthy eating behavior. This study aimed to determine if there was a difference in nutrition knowledge depending on the choice of science subject in high school and whether that affected the actual eating habits of college students in Japan. SUBJECTS/METHODS: The subjects were 514 college students, the majority first-year students, in 3 cities in Japan. A questionnaire survey was conducted on elective subjects in science in high school, diet (11 items), lifestyle (5 items), and nutrition knowledge (34 questions). The preliminary survey was conducted on 47 students in the fall of 2019, and the full-scale survey was conducted in May-June and October-November 2021 at the end of lectures for the first-year students. RESULTS: The students in the high-score group (24-31 points, n = 180) had a higher intake of vegetables (odds ratio [OR], 1.78; 95% confidence interval [CI], 1.12-2.82; P = 0.015) and breakfast (OR, 1.64; 95% CI, 1.03-2.60; P = 0.035), and a reduced intake of fast food (OR, 0.27; 95% CI, 0.14-0.51; P < 0.001) than those in the low-score group (6-19 points, n = 150). Only the biology and chemistry students had significantly higher nutrition scores than the other groups (all: P < 0.001), but no significant difference was found between the other groups. Understanding nutrition learned in elementary and junior high school is appropriate, while molecular structure, recommended amount, and food poisoning were insufficient. CONCLUSIONS: Knowledge of nutrition appears to have a positive effect on the actual eating habits of college students. Although biology and chemistry in high school may help students understand the foundations of good nutrition, specialized food education may be required to make informed dietary choices.

The aim of this study analyzed changes in dietary habits and lifestyles before and after COVID-19 targeting adolescents, using the food consumption behavior survey (2019 vs 2021). In the change in health-related factors, height decreased overall, and a significant difference was especially evident in males. Awareness that functional foods and eco-friendly foods contribute to health has increased. Among the results of dietary behavior, the frequency of skipping breakfast showed that the rate of not skipping breakfast and the rate of skipping breakfast more than 5 times increased at the same time(p=0.019). The rate of eating out decreased significantly after COVID-19, and it was analyzed that schools and school cafeteria, as well as Street carts or restaurants and academy, all increased significantly as places where snacks were not consumed. In order to analyze changes in food-related lifestyle, it was grouped into convenience-seeking, quality/safety-seeking, taste-seeking, and health/safety-seeking. 'Small packaged or pre-processed products' decreased. On the other hand, items such as 'Safety rather than price when choosing food' and 'Don't eat food that could go bad' improved. 'Tend to eat regularly' was higher than 2021 compared to 2019. Also 'Tend to purchase HACCP and GAP-certified products' are increased. Because of COVID-19 changes in lifestyle have affected the diet of adolescents. The results of this study suggest that it can be used as a guideline establishment and nutrition counseling material for the formation of correct eating habits for adolescents in the future pandemic era.

Objectives: Our previously published study showed that a workplace nutrition intervention program with personalized goal setting and smartphone-based nutrition counseling improved dietary habits and physical activity in city bus drivers who were overweight/obese. This study explored the facilitators and barriers that participants faced in achieving their dietary and physical activity goals six months after the intervention. Methods: The study included bus drivers and dietitians who participated in the intervention program. Three focus group interviews were conducted with 10 bus drivers (divided by two groups based on their achievement of set goals) and five dietitians who had provided nutrition counseling. Results: Willpower was the most important intrapersonal facilitator for drivers to achieve their goals. Other factors that promoted behavioral changes were nutrition counseling by dietitians, trackable physical activity using smartwatches, and setting of practical and achievable goals. Meanwhile, the most important barriers identified were occupational factors such as long driving hours, short breaks, and shift work. Other barriers were environmental factors such as availability of snackable food, accessibility to convenience stores, and cold weather. Family and colleagues were perceived as both facilitators and barriers. In addition, dietitians identified a lack of knowledge about healthy diet as one of the barriers. Conclusions: Our results suggested that the workplace environment should be improved and that nutrition intervention programs at the workplace could encourage bus drivers to practice healthy eating habits. The facilitators and barriers identified in this study should be considered when planning a nutrition intervention program for bus drivers.

BACKGROUND/OBJECTIVES: Unhealthy food choices among young adults are common globally, and the incidence of chronic diseases, such as obesity, is rising. Food literacy (FL) is important for improving and maintaining individual health in a rapidly changing food environment and can form the basis for following a sustainable diet. Therefore, it is essential to improve FL among young adults, particularly college students, who are in the formative years of their lifelong food habits. This study examined the facilitators and barriers of FL and related dietary behavior among college students in South Korea. SUBJECTS/METHODS: This study recruited 25 college students with different residence types using convenience and snowball sampling. In-person, telephone, and video interviews were conducted from March to November 2021. The interview data were analyzed using framework analysis based on the socio-ecological model. RESULTS: At the individual level, prior good experiences with food were the most frequently mentioned facilitator. In contrast, the major barriers were a lack of knowledge, financial hardship, irregular schedules, and academic stress. At the interpersonal level, the influences of family and peers, such as early exposure to healthy eating habits and opportunities to have easy accessibility to farms and farming, are major facilitators, but the lack of a sense of community was the major barrier. At the environmental level, the major barriers were unfavorable food environments at home and in neighborhoods, such as the absence of kitchens in housing and large packaging of produce at markets. CONCLUSIONS: Many factors affected the students' FL and related healthy eating practices. These findings suggest that a campus-based FL program should be developed by reflecting on these facilitators and barriers.

The increased number of elderly in Korea presents great challenges for community nutrition programs. Strategies to enhance elderly nutrition are needed, as well as dietary advice that are reality-based and tailored to the need of the elderly. The purpose of this study was to evaluate the overall effectiveness of an elderly nutrition improvement program(ENIP), by assessing changes in nutrition knowledge, attitudes, and behavior after program completion. ENIP was conducted in Suwon for 4 months in 1998 at 5 centers for the elderly. The program provided individual nutrition counseling and brief biweekly group education sessions. To stimulate participation and motivation, the elderly in two centers were served free milk packs(200ml) three time a week during the program(milk＋education group), and the elderly in 3 other centers were served yoghurt on the program day(education group). Altogether, 102 subjects finished the program(milk＋education group 67 ; education group 35). Data about nutrition knowledge, dietary attitudes, diet records(24 hour recall) and dietary habit was collected before(baseline) and after the program(follow-up). The Drop-out rate for the milk＋education group(2.9%) was significantly lower than that for the education group(30.0%)(p<.001). The Nutrition Knowledge fo females milk＋education group increased significantly after the program, but no significant differences were observed in other groups. Over 60% of all the elderly showed positive responses to the healthy eating attitudes. Energy, protein, vitamin A, riboflavin, Calcium and Potassium intakes improved in the male milk＋education group. The Vitamin C intake improved in the male education group. Energy and vitamin A intakes improved in the female milk＋education group and energy, vitamin A, thiamin, riboflavin, niacin, Ca nad P in the female education group. A stepwise multiple regression analysis was performed to examine the effects of food intake changes on overall nutrient quality. For all elderly, the fish intake explained 12.6% of the variance, followed by candy intake and vegetable intake(model $R^2$=19.6%). Dietary habits such as meal time regularity and salty food reduction were markedly improved in both groups. Sixty-one percent of the milk＋education subjects stated their participation was voluntary and active, while 51% of education subjects did. Sixty four percent of the subjects stated their interest on diet increased remarkably through program participation. Considering the results, it is conjectured that ENIP had a great impact on nutrient intake, dietary attitudes and habits. Milk supplement showed no direct effects on elderly nutrition improvement, but it encouraged the program by reducing drop-out rates and inducing voluntary participation. Therefore milk supplement could enhance the community nutrition education program. Moreover it is strongly suggested that the ENIP be expanded to other communities.
