The purpose of this study is to confirm the relevance between the frequency of beverage consumption and periodontal disease among Korean adults. The data used for analysis was obtained from the 6th Korea National Health and Nutrition Examination Survey (2013-2015). The subjects were 9,042 adults aged 19 to 64. In non-smoking group, people with periodontal disease had less intake of milk, carbonated beverage, and fruit juice and more intake of coffee than people without periodontal disease. In smoking group, people with periodontal disease had less intake of milk, liquid yogurt, carbonated beverage, and fruit juice and more intake of coffee than people without periodontal disease. In the results of verifying the correlation between periodontal disease and beverage intake in accordance with the matter of smoking after revising the socio demographic characteristics, in non-smoking group, the intake of coffee was correlated with periodontal disease. In smoking group, the intake of milk was correlated with periodontal disease. Since the intake frequency of some beverages is related to periodontal disease, there should be guidelines on beverage consumption during the periodontal disease prevention education.

A valid food or dish frequency questionnaire needs to be developed in Korea for accurate dietary assessment because the dietary practices of Koreans are very different from those of other countries. This study was conducted to evaluate the accuracy of the newly developed, semi-quantitative, dish-based frequency questionnaire (Semi-DFQ) with 12-day dietary records (12-DRs) as a gold standard. The study subjects were 115 men and 173 women aged 30-65 years old. We calibrated the frequency, portion size and daily intake of 112 dish items reported in Semi-DFQ with those in 12-DRs by Spearman rank correlation coefficients (SCCs). The consumption frequency and portion size reported in Semi-DFQ were higher than those in 12-DRs. The SCCs for the consumption frequency of various dishes ranged from -0.07 (fried seaweed) to 0.70 (instant coffee), the portion size ranged from -0.09 (cold seaweed soup) to 0.68 (soju), and the daily intake ranged from -0.07 (fried seaweed) to 0.71 (soju). The SCCs were higher for dishes consumed daily, such as steamed rice,milk, coffee and alcohol, than those of foods eaten rarely. The overall agreements between the Semi-DFQ and 12-DRs were low for categories of consumption frequency and portion size, even though some dishes showed high SCCs. The SCCs of the two methods in consumption frequency and amount were higher among the women and younger subject. The results revealed the limitation of the Semi-DFQ for evaluating the status of usual individual intake. Therefore, the Semi-DFQ can be used in addition as dietary records and 24-hour recall depending on the research aims.

This study was conducted to compare the effects of feeding high protein and low energy milk replacer (HPR; CP 25%, ME 3.6 Mcal/kg DM) with low protein and high energy milk replacer (HPR; CP 21%, ME 4.2 Mcal/kg DM) on feed consumption, body weight (BW) gain, health and selected blood metabolites in Holstein calves during the pre-weaning period. At each feeding, each milk replacer (MR) was prepared by mixing 0.125 kg of dry MR in 1L of warm ($60^{\circ}C$) water. The calves were fed either HPR (n = 10) or HER (n = 10) using mobile plastic bottles fitted with soft rubber nipples. All calves received 1.8L diluted MR at each feeding 3 times daily during the first 4 weeks of age; feeding frequency was reduced to 2 times daily for the next 2 weeks of age and then to once daily during the last week of the experiment. Jugular blood was sampled in calves at day 7, 14, 21, 35 and 49 of age to enumerate selected metabolites. Daily MR, starter and hay intake during the pre-weaning period were similar in calves fed HPR and HER. Consumption of starter, MGH and total DM steadily increased with the age of calves. Final BW, daily BW gain and feed efficiency of calves were not affected by treatments. Serum glucose, cholesterol, creatinine were decreased (p<0.05) and blood urea N was increased (p<0.05) in calves fed HER or HPR as they grew older. Serum glucose, total protein and albumin concentrations in calves were not affected by treatments. Serum GPT and GOT concentrations were higher (p<0.05) in calves on HPR than on HER. Scouring score, days scoured, respiratory score, rectal temperature and general appearance were similar in calves fed HPR and HER. Poor general appearance (dullness and droopy ears) of calves fed either HPR or HER reflected nutritional insufficiency and stress. In conclusion, energy and protein concentrations in MR did not affect feed intake and BW gain in Holstein calves during the pre-weaning period. Poor general appearance and lower BW gain of calves compared to those reported in the literature for milk fed calves prompt a demand for further research to improve the daily nutrient supply to MR-fed calves.

This research was designed to examine the dietary habits and unbalanced diet of middle school students by gender and region. The survey was conducted using questionnaires on dietary habits and unbalanced diet administered to 726 students (urban: 367, rural: 359). The obesity index using BMI showed that the largest proportion of girls was 'underweight' in both regions, which showed a significant difference by region (p<0.001). Male students in urban areas prefer salty taste more than rural students (p<0.05). In urban areas, problems relating to dietary habits were 'unbalanced diet' and 'overeating' in male students and 'frequent snacks' and 'irregular mealtime' for female students (p<0.01). The frequencies of skipping breakfast (p<0.01), snack intake (p<0.001), eating out (p<0.001) and fast food consumption (p<0.001) were significantly higher in urban students than in rural students, and the reason for eating snacks was 'hungry' in urban students and 'habitually' and 'delicious' in rural students (p<0.01). Unbalanced diet was significantly higher in rural students compared with urban students (p<0.001) and male students compared with female students in urban (p<0.05), and the factors affecting dietary habits were mostly related to family. Male students in urban areas showed a significantly lower intake frequency of 'fish, tofu and beans' (p<0.05) and 'milk and yogurt' (p<0.05), but higher intake frequency of 'vegetables' (p<0.001) compared with female students. Male students in rural areas showed a significantly lower intake frequency of 'meat' (p<0.05) but higher intake frequency of 'milk and yogurt' (p<0.05) compared with female students. Urban students showed a significantly higher intake frequency of food groups compared with rural students. To conclude, desirable nutrition education on meal regularity, snack choice, and problems relating to unbalanced diet should be conducted in schools.

In order to investigate the dietary intakes and physical characteristics in college women smokers, interviews using questionnaires were done on 33 smokers and 42 nonsmokers residing in seoul area. General living habits, dietary habits, food consumption frequency and nutrient intake by quick estimation were investigated through direct interviews with subjects. Subjects height, weight and blood pressure were measured, and body fat percentage were statistically analyzed using Bio-electrical Impedence Fatness Analyzer(GIF-891). All data were statistically analyzed by SAS PC package program ; percentage or mean and standard error were examined for each item, and the significant difference was evaluated by chi-square test or Student's t-test at $\alpha$=0.05. In the analysis of taste and food preference, smokers consumed larger amount of alcohol and coffee than nonsmokers ; they also disliked sweet taste. The results of food consumption frequency data also showed that smokers consumed less fish, milk and fruits but consumed more instant foods than nonsmokers. As a result of anthropometric measurements, height, age, and 패요 fat percentage showed no difference, but there was a significant difference in weight, BMI, systolic blood pressure, and diastolic blood pressure. Energy intake in nonsmokers was 1640 ㎉/day(CHO : Pro : Fat=66.0 : 14.7 : 19.3), in smokers. Intakes of calcium, iron, vitamin C, vitamin A, vitamin B1, vitamin B2, and niacin in smokers were not significantly different from those of nonsmokers.

The daily food intake and its related factors of the elderly(aged over 60) living in Incheon were compared. Self administered questionnaires were collected from 418 elderly. Statistical data analysis was completed using a SPSS v. 10.0 program. The results are summarized as follows: About 70% of elderly took grains and starch foods relatively high. The daily intakes of them was significantly influenced by ages of elderly, self-perceived health status, degree of drinking, meal regularity and nutritional balance of meals. More than 80% of elderly responded to take the food group of meat, fish and eggs poorly. Among various factors, the residence type and snack intake frequency influenced the daily intake of those foods statistically. A half of elderly took the vegetables and fruits everyday more than average. The daily consumption of vegetables and fruits was significantly influenced by sex, ages, exercise, snack intake frequency and preference of spices. Most elderly consumed fewer servings of milk and dairy products. About 60% of them did not take milk and dairy products daily. The daily contribution of those foods was significantly influenced by residence and exercise. 45.5% of elderly took oils and sugars more than average everyday which was influenced significantly by residence, exercise, snack intake frequency and meal regularity. In conclusion, the important influencing factors on the daily food intakes of elderly might be related to ages, residence, family, smoking, drinking, exercise, snack intake frequency and meal regularity. Therefore, a situation-oriented and practically organized nutrition education and ingestion support programs which consider the elderlies' socioeconomic status may help to improve the daily food intake of elderly in Incheon area.

BACKGROUND/OBJECTIVES: Hypertriglyceridemia may be a more important predictor of cardiovascular disease in Asian population consuming carbohydrate-rich foods than in Western populations. Dairy products are known to play a beneficial role in obesity, dyslipidemia, and metabolic syndrome, but the results vary depending on gender and obesity. In this study, we investigated the associations between dairy product intake and hypertriglyceridemia in Korean adults. SUBJECTS/METHODS: The participants were selected from the Korea National Health and Nutrition Examination Survey 2007-2012 (KNHANES IV and V). A total of 22,836 participants aged 19-64 years were included in the analysis. A food frequency questionnaire used to determine the frequency of consumption of products (milk and yogurt). Multivariable logistic regression was used to assess the associations between dairy product intake and hypertriglyceridemia. RESULTS: A significantly decreased risk of hypertriglyceridemia was detected in the highest dairy product intake frequency group (≥ 1 time/day) (odd ratio [OR] = 0.79; 95% confidence interval [CI] 0.64-0.97, P for trend = 0.022) compared to that for the lowest dairy product intake frequency group. Among obese participants, the group with the highest intakes of milk (in men, OR = 0.64; 95% CI: 0.46-0.91, P for trend = 0.036) and yogurt (in women; OR = 0.53; 95% CI: 0.29-0.94, P for trend = 0.019) showed inverse associations with hypertriglyceridemia. No associations were detected in normal weight participants. CONCLUSION: The association between dairy product intake and hypertriglyceridemia differed by gender and obesity status. Further prospective studies are needed to confirm these associations.

In this study, we compared diet related attributes such as food taste preference, food consumption frequency and nutrition intake between elderly residents in their 80's of areas in Jeollanam-do that are well known for longevity and those of a part of Seoul. Structured in-depth interviews were conducted by trained interviewers on 125 consented subjects (67 Jeonnam and 58 Seoul). Differences of groups were tested using Chi-square tests for nominal or ordinal data and t-tests and ANOVA tests for ratio data. The elderly from Jeonnam tended to sleep longer, express emotion more freely, and interact with others more often than those from Seoul. The elderly tended to prefer sweet or salty tastes, which might be highly related to serious health problems. The most frequently consumed foods were napa cabbage kimchi (2.19 times/day) and multigrain rice (1.99 times/day). Elderly from Jeonnam tended to consume garlic, milk, beans and roasted barley/corn teas less often; whereas, they consumed porridge, dried radish greens, potato, fermented fish, dried fish, pork rib, pork belly, soybean paste soup, soybean paste/Ssamjang, other kimchis, pickled vegetables, snacks, cookies, and green/black teas more often than elderly residents from Seoul. Differences in nutrition intake between the regions were greater than differences between the perceived levels of household economic status. NAR and INQ for folate were lower among elderly from Jeonnam than those from Seoul, while those for protein, vitamin C, niacin, vitamin $B_6$ were higher. The study results indicated that elderly from Jeonnam engaged in a more diverse diet than the elderly from Seoul.

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.
