While metabolic syndrome(MS) is rapidly expanding and dietary pattern, the known risk factor of MS, goes through heavy transition to western diet, not many researches have been done on the association between dyslipidemia and dietary factors in Korean adults. The purpose of this study was to investigate the association between compliance with dietary guidelines and dyslipidemia among Koreans. The subjects of 399 adults who visited health examination center were classified into dyslipidemia(n=180) and control(n=219). Diagnosis of dyslipidemia was based on NCEP-ATPIII criteria(triglyceride>=150mg/d, HDL-C<50mg/dl for male, HDL-C<40mg/dl for female). A questionnaire based interview was done to collect information on compliance with dietary guidelines, general characteristics and health related behaviors. Anthropometric variables were measured during the survey. Mean compliance score of dietary guideline was significantly lower in dyslipidemia group than in control. It was associated negatively with waist circumference and positively with serum HDL-cholesterol(p<0.05). Risks of dyslipidemia were significantly decreased in the group with highest dietary guideline score, high serum triglyceride levels(OR=0.484, 95% CI=0.268-0.875), abdominal obesity(OR=0.296, 95% CI=0.159-0.553), and dyslipidemia(OR=0.481, 95% CI=0.266-0.869). These results indicated that increasing compliance with dietary guidelines could be an effective strategy to lower the risk of dyslipidemia among Koreans.

Hypertension is the major risk factor for cardiovascular disease which is considered the leading cause of death in Korea. Since nonpharmarologic dietary intervention is recommended as the first step in the management of hypertension, evaluation of intervention programs is needed to formulate strategies for improving patients' dietary adherence. This study was designed to evaluate the overall effectiveness of a hypertension nutrition education program (HNEP) at a public health center, by assessing changes in nutrition knowledge, food attitude, self-efficacy, dietary behavior, and nutrient intake after program completion. An HNEP was conducted in Suwon city for 5 months in 1999 by a public health center. The program provided 3 sessions of group education with individual nutrition counseling. Thirty-five patients participated fully in the program out of 62 enrollees. Data about nutrition knowledge, food attitude, self-efficacy, dietary behavior, and intake (24-hour recall) were collected before (baseline) and after the program. Post program results indicate the following : 1) nutrition knowledge and perception of importance of nutrition significantly increased, 2) food attitudes also improved, 3) the self-efficacy for maintaining a low salt diet was increased significantly, whereas self-efficacy for maintaining a low fat diet or dietary guidelines was not improved, 4) frequency of intake of processed food, animal fat, and sweets as well as frequency of dining out were significantly reduced, 5) nutrient intake was not improved after the program, 6) the most serious barrier for participating in the program and practicing diet therapy was lack of time and willingness. In conclusion, it appears that HNEP might improve food attitudes, individual perceptions and self-efficacy for desirable eating behavior, but it might not improve dietary intake. It follows then, that a long term intervention program may need to increase effectiveness of patient dietary adherence.

Objectives: This study examined the effects of dietary education experience (home, school, and mass media) on food consumer information literacy. Methods: The study subjects were 454 adult consumers who answered a structured questionnaire. The questionnaires addressed the subjects' demographics, dietary education experience (home, school, and mass media), and food consumer information literacy. The data were analyzed through frequency analysis, mean, standard deviation, t-test, ANOVA, Pearson's correlation, and multiple regression analysis using SPSS Win 24.0. Results: First, the scores of mass media education experience were 3.41 ± 0.64, which was the highest, and 3.15 ± 0.74 for school education experience, which was the lowest. Second, the level of sub-literacies (task definition, information seeking strategy, location and access, use of information, synthesis, and evaluation) showed scores of 3.20 ± 0.72 ~ 3.47 ± 0.68, which were slightly higher than the median. The synthesis literacy was the highest, as opposed to the information seeking strategy literacy, which was the lowest. The location and access and synthesis literacy were higher in women. Third, a significant positive(+) relationship was observed between all sub-literacies and each of three dietary education experiences (home, school and mass media). According to multiple regression analysis, the major variables influencing the sub-literacies of food consumer information literacy were home education, mass media, and school education in that order. Conclusions: The dietary education experience was the highest through mass media. The factor that showed the highest food consumer information literacy was synthesis. The factors influencing the food consumer information literacy were dietary education experience through home, school, and mass media.

This study examined the satisfaction of the married women from aged 20s through 50s with well-being oriented foods, considering the importance of each subordinate field and verifying the differences between the groups according to socio-demographic factors, purchase behavior factors, and well-being oriented dietary life factors, followed by an analysis of the relative influence of those relevant factors. A preliminary survey was conducted from January 4th-11th, 2009 to check if there were any problems or misunderstood parts before the main survey. After the preliminary study was conducted, certain problems were adjusted and supplemented, and then the main survey was conducted for twenty-three days, from January 4th to February 5th, 2009. The summaries of this study are as follows: First, in the view of the purchase behavior, the mainly purchased well-being oriented foods were farm products, and the leading purpose of the purchase was for the parents and the children. It was shown that 30% or more of the information sources on well-being oriented foods were families, relatives and neighbors. More than 66% of the purchasing was done at wholesale marts and the topped purchasing frequency was from 5 to 6 per month. More than 71% of payments for well-being oriented foods were \50,000~100,000 per month. More than 51% of the respondents answered that the proper price of well-being oriented foods was 1.2 times to 1.5 times of that of other foods. Second, the satisfaction of the well-being oriented foods was ranked as 3.21 to 3.28 out of 5, and varied with the usages and the methods of weights. Investigating the satisfaction with each subordinate field, the satisfaction with price was shown to be low. The satisfaction with the assortments of foods and the satisfaction with the therapeutic degree by thorough investigation and management of foods were also relatively low. Third, well-being oriented dietary behavior was shown to be characterized by two factors, through factor analysis in this study. One was an eco-friendly oriented behavioral factor and the other was a health oriented selective factor. Fourth, the stepwise multiple regression analysis results investigating the relative influence of the factors effecting satisfaction with well-being oriented foods showed that the top ranked factor affecting total satisfaction was eco-friendly oriented behavioral factor, followed by education level and purchasing sites, especially of consumer groups.

Several nutrients are known to affect bone mineral density (BMD). However, these nutrients are combined with food intake and dietary patterns and little is known about the association of dietary patterns and BMD. The objective of this study was to investigate the association of dietary patterns with BMD in Korea Genome Epidemiology Study subjects. Among 2,884 women (40-69 yr) recruited at baseline study (2001), 861 subjects with BMD measurements at baseline and a 4-year follow up study (2005) completed the semi-quantitative food frequency questionnaire. BMD was measured by the Quantitative Ultrasound method. One hundred three food items were combined into 17 food groups and 4 dietary patterns were identified by factor analysis. Cluster analysis using factor score classified each subject into one of three dietary pattern groups named 'Rice and kimchi eating' (n = 617), 'Contented eating' (n = 124), and 'Healthy and light eating' (n = 120). The 'Healthy and light eating' group, characterized by higher intake of fruit, vegetables, fish, milk and dairy products, and younger age, more exercise, higher education, and higher income than other groups. The tibia BMD of the 'Healthy and light eating' group was higher than the other groups after adjusting for the age. After the adjustment for the age BMI and exercise, the 'Healthy and light eating' group showed significantly lower odds of tibia osteopenia/osteoporosis risk compared to the 'Rice and kimchi eating' group both at the baseline [OR(95% CI) : 0.50(0.30-0.84)] and follow-up [OR(95% CI) : 0.59(0.36-0.97)] examinations. The dietary pattern with low calorie and high intakes of fruit, vegetables, fish, milk and dairy products may have beneficial effects on BMD in middle-aged women.

The purposes of the study was to measure attitude and satisfaction concerning the service quality of university foodservices. The survey was conducted to 500 university students using questionnaires, of which 457 questionnaires were analyzed. A statistical data analysis was completed using SAS programs by the descriptive analysis. The results of the study were summerized as follows: 1) The mean frequencies of visiting the university foodservices per week were higher in males than females. The factor affecting the students on their first choice of the foodservices depended on the distance. The first complaint factor concerning the university foodservices was the taste of foods. 2) The students were not satisfied with the service quality of university foodservices personnels. The actual mean score of the service quality was 3.92 out of 5, but the perceived one was 2.94. Therefore, the satisfaction degree of the service quality was calculated as-0.98. 3) The students were more satisfied with the food quality of contracted foodservice management than that of self-operated one.

The objective of this study was to investigate important factors affecting food choice, specific dietary changes over past few years and to find out consumer opinions concerning the use of yogurt and oligosaccharides. Results of this study showed that three most important factors in food selection were taste (52.5%), nutrition (23.4%) and safety (15.8%). Three most important nutritive factors were protein (26.3%), calorie (19.2%) and vitamin (13.8%). Specific dietary changes of the respondent over past few years didn't affect meat intake, but increased vegetable and fruit intakes. Majority of the respondent (52.3%) ate yogurt more than 3 times per week and 35.6% of them ate $3{\sim}4$ times per month. Reasons for intake of oligosaccharides were as follows; low calorie (40.8%), sweetener (28.3%)and bifidogenic factor (25.0%). The respondent regarded that yogurt had more preventive effect of disease than that of oligosaccharide.

A feeding experiment was conducted to determine the use of distillers dried grain (DDG) as a partial replacement for fish meal in the diet for juvenile rockfish, Sebastes schlegeli. Four iso-nitrogenous (50% crude protein) and iso-caloric (4.3 kcal/g) diets (designated as DDG0, DDG7, DDG14, and DDG21) were formulated to contain 0, 7, 14, and 21% DDG. Triplicate groups of juvenile rockfish (initial body weight, $10.2{\pm}0.2g$) were fed one of the experimental diets to visual satiety twice a day (09:00 and 17:00) for 8 weeks. At the end of the feeding trial, survival of rockfish was above 97% and not affected by dietary DDG levels (P>0.05). Weight gain, feed efficiency and daily feed intake of juvenile rockfish were significantly decreased with increase of dietary DDG levels (P<0.05). Condition factor, hepatosomatic index and visceralsomatic index of juvenile rockfish were not significantly affected by dietary DDG levels (P>0.05). No significant differences were observed in the contents of moisture, crude protein, crude lipid and ash of the whole body and dorsal muscle in juvenile rockfish fed the experimental diets (P>0.05). Therefore dietary inclusion of DDG as a replacement for fish meal could depress the growth of juvenile rockfish.
