Epidemiological studies have indicated that a relationship between overweight and cardiovascular disease exists. To assess the relationship of unfavorable changes in serum lipid concentrations, apolipoprotein B, lipoprotein(a), blood sugar and blood pressure to anthropometric variables, nutrient intakes and dietary behavior,64 obese children were chosen as subjects and 24-hour dietary intake, dietary behavior as well as blood pressure, apolipoprotein B, lipoprotein(a), three kinds of cholesterol concentrations were measured in November 1976. More than half(57.8%) of the children had serum cholesterol concentrations over 175mg/d1, and 26.6% of them had over 200mg/d1 and this group could be classified as a high risk group. Abdominal obesity as measured with waist circumference and waist hip ratio was negatively co..elated to high density lipop개tein(HDL) cholesterol. Dietary behavior rather than nutrient intakes appeared to have associations with unfavorable lipid profiles. Total dietary behavior scores and fish and bean product consumption had strong correlations with potentially atherogenic lipoprotein concentrations. This study suggests that fir the early prevention of cardiovascular disease, waist hip ratio together with obese rate should be included in selective programs to identify risk group of children in Korea. furthermore, interventions in cardiovascular disease risk groups in obese children should emphasize maintenance of ideal body weight through reducing body fat and adopting desirable dietary behaviors such as increasing intake of fish or bean products.

The effect of dietary pectin, tangerine pulp meal, propionate, lactate or fumarate on cholesterol (C) and triacylglycerol(TG) levels in the serum and liver, and the effect of pectin on dietary C absorption were studied in a series of three experiments. Mature female Sprague Dawley rats were fed a control diet or diets containing 5% pectin, 5% tangerine pulp meal, 3% propionate, 3% lactate 3% fumarate, or 10% pectin. Serum total C levels were lower(p<0.05) in rats fed the diet containing 5% pectin than in control rats after a 4-week feeding period(93.8 vs 119.2mg/100mL). Serum HDL, LDL+VLDL C levels were not different among diet groups. Liver total C level was also lower(p<0.05) in rats fed the diet containing 5% pectin than in control rats, but liver TG level was not influenced by diet. Dietary propionate, lactate or fumarate did not reduce serum C, indicating that propionate is not a regulator of serum C. However, dietary pectin(10%) increased fecal excretion of dietary C(or its metabolites) more than 70% over a control value. Our data indicate that dietary pectin reduces serum and liver C levels by increased fecal secretion of dietary C, but not by its fermentation product propionate or other gluconeogenic substrates.

The purpose of this study was to identify dietary patterns among children and adolescents in Korea and to examine their associations with obesity and some blood profiles. One day food consumption data measured by 24-hour recalls on 2704 subjects aged 1 to 19 were used from 2001 Korea National Health and Nutrition Survey. The data of blood profiles available in the ages of 10 or older was also used. After categorizing each food consumed into 29 food or food groups, five dietary patterns were derived through a factor analysis and subjects were classified into three major dietary patterns via a cluster analysis using the factor scores. Three dietary patterns were identified as 'traditional diet' (25.6%), 'westernized-fast food' (6.2%), and 'mixed diet' (68.2%). The 'traditional diet' pattern had a higher percentage in boys. Both the 'traditional diet' and the 'westernized-fast food' had higher proportions of adolescents (12-19 y) than younger children, while the 'mixed diet' had a higher percentage of preschool children (1-5 y). Obesity rate analyzed within each age group showed no differences among 3 dietary pattern clusters. Blood pressure and all plasma profiles were not different among dietary patterns when adjusted with age and gender. Conclusively, children and adolescents in Korea had three distinct dietary patterns, which were associated with gender and age. These patterns could be useful to plan nutrition interventions for teenager health promotion.

This study were performed to investigate effect of dietary cadmium(Cd) and protein levels on growth, body protein metabolism and Cd toxicity in growing rats. Forty eight male rats of Sprague-Dawley weighing 113$\pm$2g were blocked into 6 groups accoridng to body weight. Dietary protein were given at the levels of 7, 15 and 40% of diet and Cd (200ppm)were either added or not. The result obtained were summerized as follow; 1) Food intake, weight gain, FER PER, liver and kidney weight, weight and length of bones, hematocrit, and hemoglobin content in Cd-added groups were low than those in Cd-free groups. 2) Serum total protein showed no significant difference with Cd addition, but it was significantly lower in low protein diet groups. Liver protein in Cd-added groups was lower than Cd-free groups, and was tend to be increased with increasing dietary protein level. 3) Daily urinary and fecal nitrogen excretions in Cd-added groups were lower than Cd-free groups, and were increased with increasing dietary protein level. 4) Cadmium contents in blood, liver, kidney, and femur were tend to be decreased with increasing dietary protein level. Especially, Cd content in kidney of Cd-added groups was significantly decreased with increasing dietary protein level. 5) Daily urinary and fecal Cd excretions were tend to be increased with increasing dietary protein level, and Cd-added-high protein diet group showed the highest Cd excretion among the Cd-added groups, Cd absorption ration and Cd retention ratio were tend to be decreased with increasing dietary protein level.

Differences in dietary habits between Korean smokers and non-smokers were investigated using information obtained from 7,370 adults, aged 20 years and older who participated in the 1998 Korean National Health and Nutrition Sulvey. Dietary habit data including: skipping of meals, meal regularity, meal volume, snacking habits, removing fatty portions before eating foods, and dietary supplement intake were collected using a structured questionnaire by interview. Individual smoking data was also collected by interview as part of the health behavior survey. A Chi-square test was used to test the association between the dietary habits and smoking. 66.9% of the men were smokers (daily current or occasional current), while only 6.7% of women smoked. On average, 34.7% of the subjects were smokers. Smokers were more likely than nonsmokers to engage in the following dietary habits considered unhealthy: skipping breakfast, meal irregularity, large dinners, small breakfasts, frequently eating out, and eating food without removing the fatty portion. Therefore, Korean smokers should be provided education to assist them in making healthy dietary choices such as: eating regular meals, small dinners, and removing fatty Portion of foods. The survey also revealed that a substantial percentage (about 20%) of the subjects were taking some kind of dietary supplement, regardless of smoking status. It is, therefore, alto necessary to inform the general public that a balanced diet is the ideal way to obtain nutrients for optimal health.

This study was evaluate the effects of community based nutrition education program offered to 3rd grade elementary school students. Students enrolled in intervention programs 4 times per class by nutrition teacher & public health center. The subjects were asked to 606 students fill out a questionnaire before and then after completion of community based nutrition education program. After completion of the community based nutrition education program, nutrition knowledge score increased from $5.07{\pm}1.65$ to $6.24{\pm}1.53$ (p<0.001), dietary attitude score increased from $16.79{\pm}2.70$ to $19.52{\pm}2.71$ (p<0.001), dietary behavior score increased from $4.79{\pm}1.23$ to $5.31{\pm}1.14$ (p<0.001). The changes in nutrition knowledge scores were positively correlated with dietary attitude and dietary behavior. Above results showed that community based nutrition education program was effective for the improvement of dietary habits of 3rd grade elementary school students. Therefore this study is suggested effective Community-Based Participatory Research public health program and this program can be used at school and at public health centers.

In order to investigate dietary risk factors for hypertension in th elderly, dietary intakes and dietary habits of 405 elderly subjects, aged 60-94, were assessed by the questionnaire, anthropometric measurement and a 24-hour dietary recall. The prevalence of definite (>95mmHg for diastolic or>160mmHg for systeolic blood pressue) and borderline(90-95mmHg for diastolic or 140-160mmHg for systolic blood pressure) hypertensive subjects 33.3% and 19.3%, respectively. The distribution of the subjects for Body Mass Index(BMI), waist-hip ratio, and alcohol consumption were significantly different among definite, borderline, and normal groups(p<0.05). The distribution of the subjects for smoking, exercise, and preference of salty food were not significantly different among definite, borderline, and normal groups(p>0.05). From the generalized logistic regression analysis of the risk factors for the hypertension, the subjects with over 27 of BMI had significantly higher risk of hypertension. Alcohol consumption and preference of salty food were significant risk factors of hypertension in the elderly. Dietary risk factors for the hypertension that had significant relationship to the hypertension were intakes of potassium, calcium, phosphate, sodium, vitamin B1, niacin, and folate. There was no significant difference of consumption frequencies of food and dish among definite, borderline, and normal groups(p>0.05). The amount of intakes for cereals and grain product, bean and their products, eggs were significantly different among definite, borderline, and normal groups(p<0.05). In summary, the amount of dietary intakes to hypertension in elderly population. Longitudinal studies for dietary risk factors on incidence of hypertension are needed in general population, especially in the elderly.

This study was conducted to investigate the dietary habits and assess the dietary intake of preschool children. Food habit, preference and nutritional supplement status were investigated using a questionnaire answered by the mothers of 453 subjects aged 3 to 6 years old. Also, a dietary intake survey using a 24-hour recall method was performed by mothers of the children. It was found that 81.2% of subjects had milk, dairy products, cookies, fruit and bread between meals once or twice per day. As well, 60.3% of subjects had an unbalanced diet and 20.7% had an overeating habit. Thus, unbalanced diet was a serious problem for many of the subjects. Due to weight controls, digestion problems and allergies, 11.7% of subjects had special dietary consideration. And 26.4% of subjects were using nutritional supplements. From the 24-recall survey, it was found that all nutrient intakes were higher than the Korean RDA except calcium and vitamin A. Nutrient intakes for protein, calcium, phosphorus and vitamin B2 were significantly different by sex, and also increased with age but not significantly. Children received 35% of daily energy, 44% of daily fat and 52% of daily calcium from snacks, so snacks clearly play an important role in dietary intake. The average number of foods consumed per day by subjects was 17.6 and that dishes was 11.0. Most children consumed 4 or 5 food groups per day. In conclusion, the dietary intake of children aged 3 to 6 were deemed adequate judging from nutrient intake and dietary diversity. More attention should be paid to the nutritional value of snacks in this age group.

BACKGROUND: A higher frequency of family meals is associated with good dietary habits in young people. This study focused on the relationships of family meal frequency with food neophobia and personality traits in adolescents. SUBJECTS/METHOD: For this purpose, we administered a survey to 495 middle school students in Seoul metropolitan city, after which the data were analyzed using the SPSS (18.0) program. Pearson correlation was used to determine the relationships among dietary habits, personality traits, and food neophobia according to frequency of family meals. RESULTS: Dietary habits, personality traits, and food neophobia all showed significant differences according to the frequency of family meals. Further, eating regular family meals was associated with good dietary habits (P < 0.001) and was linked with improved extraversion, agreeableness, conscientiousness, emotional stability, and openness/intellect (P < 0.001). On the other hand, it showed a negative relationship with food neophobia (P < 0.001). The relationship between dietary habits and food neophobia showed a negative correlation (P < 0.01). The relationship between dietary habits and personality traits showed a positive correlation (P < 0.01). Lastly, the relationship between personality traits and food neophobia showed a negative correlation (P < 0.01). Conclusion: Based on the results of the study, the frequency of family meals affects dietary habits, personality traits, and food neophobia in adolescents.

The effect of dietary fatty acid supplementation on milk production, milk composition and plasma constituents in dairy cows was examined. Dietary fatty acids including mainly palmitic acid and stearic acid were given to cows from 2 weeks before and 8 weeks after parturition. Weekly gain of daily milk production was increased gradually during early lactation period and reached a plateau at 4 weeks after parturition. Weekly gain of daily milk production in lactating cows received dietary fatty acids was significantly higher than that of cows given a control diet alone. Although milk lactose concentration was slightly decreased by dietary fatty acid supplementation, milk fat and protein were not significantly influenced by dietary fatty acid supplementation. Dietary fatty acids did not affect plasma concentrations of triglyceride, non-esterified fatty acids, total cholesterol, high-density lipoprotein cholesterol and glucose during postpartum. It is suggested that dietary fatty acid supplementation has the potency to enhance energy balance and improve milk yield without any adverse effects on milk composition.
