This study was performed to investigate the preference and consumption pattern on milk and milk products of middle and high school students. The subjects were 1,195 students(590 middle school and 605 high school students) living in Geochang area. The survey was conducted by using a self-administered questionnaire in November, 2004. The results were as follows. Sixty-three point four percent of the subjects liked milk, and the main reason was 'accelerate growth and development'(55.4%). Preferred tastes of milk were 'savory taste'(35.4%) and 'sweet taste' (29.9%). Banana milk, chocolate milk, strawberry milk, ice cream, yoplait and yogurt were highly preferred. General preference for different kinds of milk was significantly higher in high school students and male students than in middle school students and female ones. With regard to preference for dairy products, cream (p<0.01) and butter(p<0.05) was preferred more by male students than by female ones, ice cream(p<0.05), yoplait (p<0.05) more by female students than male ones. The score of milk intake frequency was 3.84(3-4 times a week) out of 5 points(7 times a week) for white milk, and that of chocolate milk was 1.98, banana milk 1.96, strawberry milk 1.72, coffee milk 1.65, showing that these products were drank less then once a week. In addition, the white milk intake frequency was significantly higher in middle school students and male students than in high school students and female students(p<0.001). Preference for milk showed a positive correlation with preference for dairy products (r=0.543, P<0.001) and frequency of milk intake(r=0.429, P<0.001). This suggests that those who prefer milk high tend to prefer dairy products and to show high milk intake frequency. In addition, milk intake frequency was in a high positive correlation with dairy product intake frequency(r=0.648, P<0.001).
The aim of this study is to provide the fundamental information on satisfaction for school food service and dietary habits of middle school students in Sejong Special Self-Governing City. Generally, the subjects had a high satisfaction level for school food service. The boys had comparatively more satisfactory days for school food service than the girls. The most dissatisfactory factors of school food service were the taste and variety of menu for the girls, and the time and place for lunch and the service of employee for the boys. The intersexual differences existed with a significant difference in the irregular intake of meals, the reasons to skip meals, and the eating speed. For the boys, the main reason to skip meals was due to lack of appetite, and for the girls, it was the weight-control. The boys finished each meal within 5~10 min and ate more than the amount the girls eat in general. The main components of breakfast for the subjects were a cooked rice, soup, and side dish in 65.9%, and the frequency of skipping breakfast was high with 32.8%, which was once per week. The favorite snacks for the middle school students were cookies and beverages in 29.4%, instant foods in 24.3%, and hamburger and pizza in 21.4%. The intake frequency of snacks was once or twice per week in 46.5% of the subjects. In addition, the subjects had a very high intake frequency of fastfoods with once or twice per week in 72.7%, and the most favorite fastfood was ramen in 57.7%. The subjects in 45.3% took dairy food every day. In conclusion, the middle school students need nutrition education to improve their eating habit and to increase the frequency of breakfast.

Precise and correct assessment of nutrient intake using appropriate dietary intake method is necessary to improve the nutritional status of the target people group. It is more likely so in elderly people since their dietary habits and inadequate nutrient intakes are of special concern even worse in rural areas. Two popular methods of gathering dietary intake are 24-hour recall and food frequency method (or food frequency questionnaire). In the present study, we conducted both 24-hour recall and food frequency method on 120 rural elderly people $(aged\;65{\sim}74\;years)$, 62 male and 58 female. The dietary intakes were analyzed and the correlation of the dietary intake between 24-hour recall and food frequency method to determine the reliability between two methods. Also each nutrient intake was compared to recommended dietary allowance (RDA) or nutrient reference value (NRV) as appropriate. Even correlation did not show significance between the two methods except for dietary fiber intake (0.65 at p<0.01) and energy-yielding nutrients which mostly showed similar results with nutrient intake level. These support the possible reliability between 24-hours record and food frequency method that is also shown on the cases of most mineral and vitamin intakes. Thus, the food frequency method used in this study for the assessment of nutrient intakes of the elderly people would be reliable for the assessment of the nutrient intake along with the 24-hour recall. Also, the present study results suggested that rural female elderly people would be under optimal nutriture status due to the lower food intake measured by 24-hour recall. The optimal food frequency method would be considered to be developed for the precise nutrient assessment.
The purpose of this study was to investigate the relationship between frequency of coffee consumption, metabolic biomarkers, and nutrition intake in adult participants in the combined 2007~2009 Korean National Health and Nutrition Examination Survey (KNHANES). Subjects (2,095 males and 3,297 females) were classified according to sex and frequency of coffee consumption (${\leq}1$ time/month, ${\geq}2$ times/month and ${\leq}6$ times/week, 1 time/day, 2 times/day, 3 times/day) using food frequency questionnaires. Nutrition intake was analyzed using 24 h recall data. The 3 times/day coffee consumption group had a significantly higher age, and frequency of smokers and drinkers compared to the ${\leq}1$ time/month coffee consumption group in both male and female participants. Males in the 3 times/day coffee consumption group had a significantly lower HDL-cholesterol level, but females had a higher waist circumference compared with the ${\leq}1$ time/month coffee consumption group. Males in the 3 times/day coffee consumption group had a significantly lower nutrient density of fiber, vitamin B2, vitamin C, calcium and phosphorus compared with the ${\leq}1$ time/month coffee intake group. Females in the 3 times/day coffee consumption group had a significantly higher nutrient density of fat and niacin, but lower nutrient density of carbohydrate, calcium, phosphorus, and iron compared with the ${\leq}1$ time/month coffee intake group. In males, the frequency of coffee consumption was not associated with the levels of metabolic biomarkers. In females, the frequency of coffee consumption was positively associated with diastolic blood pressure after adjustments for multiple confounding factors, including age, BMI, smoking status, alcohol consumption, physical activity and energy intake. Coffee consumption was associated with decreased diastolic blood pressure in females. These findings suggest the importance of an awareness of the association between coffee consumption and metabolic risk.

The purpose of this study was to compare food intakes between Korean breast cancer patients and a healthy control group. We compared the intake of nutrients of 117 food items between Korean breast cancer patients (n=97) and age matched healthy controls (n=97). Nutrient intake was estimated using a quantitative food frequency questionnaire. The mean caloric intake of breast cancer patients and healthy controls was not significantly different. Breast cancer patients consumed significantly less fat and antioxidant nutrients such as vitamin A, retinol, ${\beta}-carotene$, vitamin C and vitamin E when compared to the control subjects. Among the food items, the intake of eggs (p<0.01), legumes (p<0.05), vegetables (p<0.05), seasonings (p<0.001), and oils and fats (p<0.01) in breast cancer patients was significantly lower than that in the controls. These results suggest that Korean breast cancer patients consumed less amount of soy and vegetables, which are rich source of antioxidant nutrients and phytosterols. Thus, dietary guidance to increase intake of these foods may be beneficial in the prevention of breast cancer.
This study examined the difference of dietary intake behavior between groups of adults aged >20 years with or without dyslipidemia, and comparing the various types of dyslipidemia, based on the Seventh (2016) KNHANES. Men showed higher rate for triglyceridemia and LDL-cholesterolemia than women and subjects in the age group 50-59 years exhibited the highest incidence of triglyceridemia, total cholesterolemia and HDL-cholesterolemia. The ratio of obese people was higher in most types of dyslipidemias. The top five foods in each group of cereal & grain, meat, vegetable, and fruit were selected for analysis, based on the food frequency. The dyslipidemia group showed higher intake frequencies for mixed grains, cabbage kimchi and leafy vegetable than the no-dyslipidemia group, and the group with high blood total cholesterol for mixed grains, apple, and cutlassfish-croaker. Group with high blood triglyceride showed higher intake frequencies of rice and mackerel-mackerel pike than the other groups of high blood triglyceride. No food showed significant difference in the frequencies between groups of LDL-cholesterol. Group with high blood HDL-cholesterol showed higher intake frequency of bibim-fried rice, deep fried chicken, stir fried chicken, apple, tangerine, banana and butter-margarine. These results indicate that people with high levels of blood total cholesterol are more concerned with food having health benefits than those with abnormal levels of other blood lipid. More information on dietary benefits need to be provided to patients having high levels of triglyceride, LDL-cholesterol and HDL-cholesterol.
Little data exists on metabolic syndrome (MetS) related with intake, especially for the South Korean. The purpose of this study was to develop and evaluate a food frequency questionnaire (FFQ) for nutritional assessment in the population with MetS in South Korea. Randomly selected female participants, mean age 21.9 years (n = 38) were invited to answer the FFQ twice (FFQ1 and FFQ2) over a nine-month interval and to complete twelve-day diet records (DR) during the months between in South Korea. The correlation coefficients for nutrient intake between FFQ1 and FFQ2 varied from 0.253 (niacin) to 0.573 (cholesterol), and the energy intake-adjusted correlation coefficients ranged from 0.187 for protein to 0.662 for iron. The energy intake-adjusted and de-attenuated correlation coefficients for comparison of FFQ1 and the DRs ranged between 0.277 (vitamin $B_1$) and 0.768 (fiber), and between 0.229 (zinc) and 0.859 (fat) for comparison of DRs with FFQ2. The percentages of study subjects classified into the same quartiles in both the DRs and FFQ1 ranged from 15.8% (vitamin $B_6$) to 47.4% (calcium), and for the same quartiles in DRs and FFQ2 from 13.2% (vitamin $B_1$) to 44.7% (potassium). The FFQ has reasonably good validity and reproducibility. Further research is needed for an assessment of reproducibility and validation of present FFQ in the subjects with MetS.
This study was performed to provide fundamental data on the dietary life according to the acculturation degree. The subject was 305 Chinese students in South Korea region. The questionnaire respondents are consisted of 148 male students (48.5%) and 157 female students (51.5%). There was a statistically significant difference in age, education level, residence time, and Korean language ability according to acculturation degree (p<0.05), but there was no statistically significant difference in gender, residence pattern, purpose of coming to Korea. There was a statistically significant difference between meals frequency, outside frequency, and the intake of Chinese food according to acculturation degree (p<0.05), but there was no significant difference in snake taking frequency (p>0.05). There was a statistically significant difference in drinks and computer time according to acculturation degree (p<0.05), but there was no statistically significant difference between smoking and exercise (p>0.05). The food intake style of Chinese students was 2.47 in noodles, 2.34 in lunches and 2.15 in breads. According to the acculturation degree, the food intake patterns showed statistically significant differences in dumping kind, congee, hamburger and pizza, while meat products, smoked meat, noodle, lunch, cereal, kimbap, sandwich. And there was no significant difference. The correlation between the factors influencing the acculturation degree of Chinese students showed a statistically significant effect on dietary habits, food intake, education level, residence period, and Korean language ability.

Purpose: Although excessive intake sugar may increase the overall energy intake, it leads to a reduction in the intake of foods containing other nutritionally adequate calories. Excessive sugar intake can also lead to an unhealthy diet, weight gain, and risk of metabolic disorders. The purpose of this study was to assess the recognition by college students, their frequency of eating sugar containing foods, and suggesting sugar reduction in the menus of institutional foodservices. Methods: A questionnaire was used to survey 145 college students to evaluate their recognition and eating frequency of consuming sugar containing foods. Subsequently, sugar reduction menus for institutional foodservice were suggested. Results: Most of the subjects (80.0%) were aware of the meaning of sugar reduction. The necessity of reducing sugar in their meals was recognized by 57.8%. These participants tended to check nutrition labeling more. Eating frequencies of sugar containing foods were not significantly different by the subjects' BMI, but they were significantly different by gender, when evaluating cooked foods. We suggested 20% sugar reduction recipes of Korean style barbequed pork, and sweet and sour chicken for institutional foodservices. Conclusion: The awareness of college students and the knowledge regarding sugar reduction were low. Sensory acceptabilities of Korean style barbequed pork and sweet and sour chicken were not significantly different, until the benefit of 20% sugar reduction was mentioned. Thus, continuous education for reduction of sugar intake are required, and also efforts are needed to develop menus containing less sugar.
The purpose of this study was performed to evaluate the prevalence of overweight and to compare the dietary behaviors, nutrient intake and physical activities of specialized game high school students. Total of 163 subjects participated and their weight, height, waist circumference, hip circumference and bone status by a quantitative ultrasound method were measured. The subjects were surveyed by a self-administered questionnaire about general characteristics, dietary behaviors and physical activities. Nutrient intakes of the subjects were assessed by semi-quantitative food frequency questionnaire. The subjects were divided into four groups on their obesity level by BMI. The prevalence of underweight, normal, overweight and obese group was 6%, 58%, 16%, and 20% respectively. BMI was negatively correlated with bone mineral density (p < 0.01) and positively correlated with WHR (p < 0.01). The dietary guideline compliance score for "Enjoy Korean rice food style" was 2.63, followed by "Prepare food sanitarily"2.48, "Do not skip breakfast"2.29, "Eat a variety of vegetables, fruits, dairy products daily"2.25, "Drink water instead of beverage"2.10, "Choose less fried foods"2.09 and "Maintain healthy weight"1.91. The exercise frequency of walking was not significantly different between groups; however, heavy exercise frequency was significantly lower in underweight group than the other groups (p < 0.05). The energy intake was 2153 kcal, which was 81.2% of the Estimate Energy Requirement, and the intake of calcium and vitamin $B_2$ was 66.7% and 77.8% of KDRIs. Particularly, the intake of iron, vitamin A and vitamin C was about 59.4%, 52.2% and 55.4% of KDRIs and INQ was 0.71, 0.63 and 0.65 respectively, and intake of folic acid fell behind 39.1% of KDRIs and INQ was 0.46. Our study suggests that the systematic and continuous nutrition education will have to be provided at schools to improve dietary and health behaviors and prevent chronic metabolic disease for students of specialized game high school.
