To assess the food intake and diet quality of Koreans living in rural areas with discriminative environment, this dietary survey was conducted with 553 subjects living in five different rural areas using a one-day, 24-hour recall method. The average weight of total food intake was 1066g, with vegetable and animal food comprising 83.75 and 16.3% of total food intake, respectively. The average daily food intakes of residents in the five areas were 985g, 1005g, 1028g, 1318g, and 964g, and were significantly different(p<0.001). Residents of Ulju consumed the largest amount of food, 1318g. The total number of food items consumed was 336. The foods consumed in largest amounts were rice(223g), Korean cabbage-Kimch'i(111g), and soybean curd(41g). The foods consumed most frequently were rice, Korean cabbage-Kimchi, green onion and garlic. When investigating the consumption pattern of the major five food groups, only 5% of subjects consumed all five groups. The groups most frequently missing were dairy products and fruits. The average number of foods consumed per day was 16.8, but differed significantly by area(p<0.001). The number of major food groups (DDS, dietary diversity score) and that of food items(DVS, dietary variety score) correlated positively with NAR (nutrient adequacy ratio) and MAR (mean adequacy ratio). People with a DDS of above 4 or DVS of above 20 met two-thirds of the recommended dietary allowance for most nutrients. When assessing the dietary quality of subjects using DDS and DVS, many people appeared not to have a desirable food intake. dietary guidelines should be made considering the nutritional characteristics of different areas to improve the health of people living in those areas.
This study was conducted to evaluate the food habits and nutrient intake of preschool children by investigating their food and snack consumption. To accomplish this, a food habit questionnaire and dietary intake survey was administered to 148 children between 2 and 6 years of age (average 4.8 years). According to the Kaup index, the underweight, normal, overweight and obesity levels of the subjects were 4.7, 60.1, 26.4, and 8.8%, respectively. In addition, the total energy intake met the EAR ($1433.94{\pm}369.70kcal$), whereas the protein, iron, phosphorus, vitamin B and vitamin C levels exceeded the EAR and the RI. Furthermore, the nutrient intake profile revealed that the mean caloric value of breakfasts consumed by preschool children in Daegu (403 kcal) was significantly (p<0.001) higher than that of preschool children in the Gyeongbuk area (271 kcal). Additionally, preschool children in Daegu ($382.96{\pm}255.79kcal$) usually consumed significantly (p<0.01) less food than those in the Gyeongbuk area ($413.82{\pm}275.43kcal$). The preferred snacks among subjects (in descending order) were milk, bread, fruit, potato or sweet potato and cookies. The mean score of the Food Habit was $3.72{\pm}0.35$ out of 5, although the score of preschool children in Daegu ($3.77{\pm}0.32$) was significantly (p<0.05) higher than that of children in the Gyeongbuk area ($3.65{\pm}0.32$). Taken together, these results indicate that there were significant differences in the Food Habit and nutrient intake level of children in Daegu and the Gyeongbuk area. Therefore, parents and caregivers should be aware of the importance of the nutritional status of preschool children and choose healthy snacks for them.
Purpose: This study examined the association of the type and frequency of coffee consumption with the health-related quality of life and metabolic bio-markers in adult men and women from the 2013 ~ 2016 Korea National Health and Nutrition Examination Survey (KNHANES). Methods: A total of 11,201 subjects (4,483 men and 6,718 women) were classified according to the type of coffee consumption (non-coffee, black coffee, 3-in-1 coffee) and type and frequency of coffee consumption (non-coffee, ${\leq}2$ times/day of black coffee, > 2 times/day of black coffee, ${\leq}2$ times/day of 3-in-1 coffee, > 2 times/day of 3-in-1 coffee) using food frequency questionnaires. Dietary nutrient intake data were assessed using food frequency questionnaires. The health-related quality of life was measured using the EuroQol-5 dimension (EQ-5D) and EQ-5D index score. Data on metabolic bio-markers were obtained from a health examination. Results: Among men and women, the proportion of subjects with an energy intake below the estimated energy requirement (EER) was lower among the 3-in-1 coffee consumption group, and the proportion of subjects with iron intakes below the estimated average requirements (EAR) was lower among the 3-in-1 coffee consumption group. Women (OR: 0.810, 95% CI: 0.657 ~ 0.998) with the ${\leq}2$ times/day of 3-in-1 coffee had a lower risk of impaired health-related quality of life (lowest 20% level in the EQ-5D score) compared to the non-coffee consumers after a multivariable adjustment. In both men and women, the type and frequency of coffee consumption was not associated with metabolic bio-markers risk after multivariable adjustment. Conclusion: These results suggest that 3-in-1 coffee consumption may be associated with a lower risk of impaired health-related quality of life and may not be associated with the metabolic bio-markers risk in adult men and women.

BACKGROUND/OBJECTIVES: The aim of this study was to identify the effect of dairy products, milk and yogurt on osteoporosis incidence among Korean postmenopausal women using prospective cohort data. MATERIALS/METHODS: Between 2001 and 2003, 10,038 participants were recruited in rural and urban areas for a baseline examination of a community-based cohort study. Of those, 1,573 postmenopausal women (aged 40-69 years at baseline) were eligible for the present study. Intakes of dairy products, milk, and yogurt were assessed using a validated semi-quantitative food frequency questionnaire. The speed of sound at the radius and tibia were measured using a quantitative ultrasound device and osteoporosis was defined based on the WHO criteria (T-score ${\leq}-2.5$). RESULTS: During the 4-years follow-up study, the cumulative incidence of osteoporosis was 18.4% (273 cases) in the radius and 33.6% (407 cases) in the tibia. The subjects with higher frequency of dairy product consumption showed a decreased risk of radius osteoporosis after adjusting for potential confounders [hazard ratio (HR) = 0.51, 95% confidence interval (CI): 0.33-0.80 for >1 time/day vs. non consumer; P for trend = 0.0027]. Similarly, high frequency of milk and yogurt consumption had a protective effect on radius osteoporosis risk [milk: HR = 0.60, 95% CI: 0.42-0.87 for > 5-6 times/week vs. non consumer (P for trend = 0.0130), yogurt: HR = 0.51, 95% CI: 0.30-0.85 for > 5-6 times/week vs. non consumer (P for trend = 0.0167)]. However, high dairy products consumption was not related with tibia osteoporosis. CONCLUSIONS: This study suggests that daily intake of dairy products could potentially reduce radius osteoporosis incidence among Korean postmenopausal women.
The purpose of this study was to evaluate the multilateral weight control program provided by the university health care center for female college students. The program was 8weeks long and composed of nutrition consultation, exercise, and behavior modification. Nutrition education focused on a low calorie and balanced diet, increasing the intake of protein and micronutrients and reducing carbohydrate and fat consumption. Evaluations were made upon completion of an 8-week program and upon follow-up at 6 months after the end of program. A total of 92 women completed the 8-week program, while 20 completed the follow-up survey. Upon completion of the 8-week program, significant decreases in body weight, BMI, body fat (kg), and %body fat were observed, and muscle mass was also reduced. The total energy and carbohydrates intake were also significantly decreased in subjects with weight loss, while the percentage of subjects whose consumption of protein, calcium, iron, vitamin $B_1$, $B_6$, and niacin did not meet the EAR, were decreased. The blood values of glucose, total cholesterol and HDL-cholesterol were decreased. The follow-up survey revealed that the subjects continued to lose weight after completion of the program. In addition, a Mini nutrition assessment revealed that diet quality improved, especially with respect to reductions in the consumption frequency of fried, greasy and salty food. In conclusion, the multilateral weight control program with diet education for female college students was effective for long lasting weight control and improved dietary behavior. Nutrition education for weight reduction should focus on balanced nutrition as well as lowering the total caloric intake.
This study was conducted to evaluate the overall dietary habits and nutritional status of 294 elementary school students located in Gwangju using the NUTRILITE nutrition quotient (NQ). The NQ score of the subjects was 59.5 out of 100, which corresponds to the level requiring "monitoring". Compared to the 64.4 score of students in the 5th and 6th grades of six metropolitan cities, the scores of the present subjects were lower. The NQ components were 57.4 for balance factors, 52.4 for moderation factors, 55.0 for diversification factors, 57.6 for practice factors, and 80.1 for environmental factors. Regarding the characteristics according to the NQ level, the score (61.5 in 7 times/wk vs. 55.3 in 1-2 or none times/wk) tended to be higher in subjects who frequently eat with their families (p<0.001). In conclusion, nutrition education should be provided to students to increase the frequency of meals with their families, to develop a habit of exercising regularly, and reduce the consumption of ramen, cookies, and processed drinks that are frequently consumed. These results can be used as basic data to develop nutrition education programs to improve the dietary habits and nutritional status of students in Gwangju.
Purpose: This study examined the influence of the consumption values on the attitudes and purchase intentions of consumers towards gluten-free products and compared consumption values, attitudes and purchase intentions according to the degree of health consciousness of the consumer. Methods: The data was collected from July 20, 2016 to August 2, 2016 through a questionnaire survey from three hundred and six consumers who had knowledge of gluten-free products. The data was analyzed by factor analysis, reliability analysis, multiple regression analysis, and an independent sample t-test using the SPSS program. Results: The regression results showed that the exploratory value (p<0.01) had a negative influence on the attitudes, and the functional value (p<0.001) and emotional value (p<0.001) had a positive influence on the consumers' attitudes. In addition, the attitudes (p<0.001) toward gluten-free products had a positive influence on the purchase intentions. Finally, the high health consciousness group answered with a significantly higher score on the consumption values, attitudes and purchase intentions than the lower group. Conclusion: These results highlight the causal relationship among consumption values, attitudes, and purchase intentions of consumers towards gluten-free products, and can provide a basic understanding of gluten free products regarding both marketing strategy and consumers' needs. The potential implications for gluten-free products manufacturers, limitations and future research directions are also discussed.
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.
BACKGROUND/OBJECTIVES: Observational studies suggest that an association between vegetable consumption and coronary heart disease (CHD). However, the results are inconsistent. This study aimed to investigate the daily intake of vegetables on a national level and its effect on the risk of CHD risk, as determined by the Framingham Risk Score (FRS). SUBJECTS/METHODS: This study was conducted a cross-sectional design of 2,510 male adults 40-64y of age who participated in the 2007-2009 Korean National Health and Nutrition Examination Survey. Daily intake of vegetable was assessed by 24-h recall, and the consumption frequency of vegetables was determined using a food frequency questionnaire. The odd ratio of CHD risk according to daily intake and frequency of vegetables was analyzed. RESULTS: Total vegetable intake was inversely and significantly associated with the risk of CHD (Model 1: 4th vs. 1st quartile, OR = 0.74, 95% CI = 0.58-0.96, P for trend = 0.0015), and the significant relationship with CHD risk remained even after adjusting for potential confounders (Model 3: 4th vs. 1st quartile, adjusted OR [aOR] = 0.69, 95% CI = 0.49-0.95, P for trend = 0.0492). Subjects in the higher quartiles of non-salted vegetable intake had 31% lower odds of the risk of CHD compared to those in the lowest quartile after adjusting for various potential confounders in model 3 (aOR = 0.69; 95% CI = 0.49-0.97, P for trend = 0.0478). No significant associations between the frequency of vegetable intake (total, green, white and red vegetable) and the risk of CHD were found. CONCLUSIONS: The major results of this study indicate that higher vegetable intake may help prevent CHD in Korean men.
This study was conducted to investigate preference for convenience food and dietary attitude in college students in Seoul and Kyunggi-do area. This study used a questionnaires as instrument tool. Thequestionnaire consisted of socio-demographic characteristics of the subjects, the valuation of preference for convenience, the concern of nutrition, and the dietary attitude. The subject were 199 males and 137 females. The mean age of subjects was 22.4$\pm$2.3year. The results have been summarized as follows Male students preferred more convenience food than females. Male students liked chicken, ice cream, ramyeon, pizza·hamburgerandfemalestudentslikedchicken,pizza, ice cream, ramyeon·hamburger. The kinds of convenience foods for a substitute meal were ramyeon, hamburger, bread, potato in male group and female group had frequently ramyeon, hamburger, bread, rice cake for a substitute meal. Male students were more likely to eat ramyeon (p<0.01) and purchased sabalmyeon The subjects used to purchase sabalmyeon as main convenience food at convenient store The score of preference for convenience food in male group was higher than female group. The score of attitude toward balanced diet in female group was higher than male group(p<0.01). In scores of concern for nutrition information, balanced diet, and nutrition knowledge, Female group had higher scores of concern for nutrition information, balanced diet, and nutrition knowledge than that of male group (p<0.01).There was no significant difference in the degree of preference for packing types, however, Male group tended to prefer more micro wave type than female group. The persons to affect the consumption of convenience food were friends. There was no significant difference in the time of purchase convenience food, however, Male tended to purchase convenience food at the time of snack than female group. As a results, proper nutritional education and qualitative development of convenience food are required in order to improve the consuming attitude of consumers and their preference for convenience food.
