This study was conducted to investigate variables related to dietary fiber intake among sixth grade children in an elementary school in Daejon city. One hundred and forty-seven children completed a questionnaire for determining their socioeconomic background and their food habits. Anthropometric measurements were taken, and a 24-hour diet recall method was used to collect three-day food intakes. The socioeconomic status of the children's families belonged to the upper middle class; 53.0% of their fathers and 25.8% of their mothers had completed college or higher degrees. 27.9% of the mothers had jobs, including part-time jobs. Approximately 30% of the children skipped breakfast, 66.4% of the children preferred animal foods to plant foods, and 52.4% of the children preferred green vegetables to yellow or pale vegetables. Grilled meat dishes, such as Grilled beef rib with seasoning, Bulgogi, grilled pork belly and beef steaks, were the most popular types of food eaten outside home by the children. Daily dietary fiber intake was 14.5 g in boys and 14.5 g in girls, and these intakes are low compared to the standard guidelines. The average intakes of energy and protein of the children were 84.5% and 114.0% of the Korean Recommended Dietary Allowances (RDAs), respectively. Besides energy, riboflavin, iron and calcium intakes were below the RDAs, and especially calcium intake was only 50% of the RDAs. On the other hand, thiamin, niacin, ascorbic acid, protein and phosphorus intakes exceeded the Korean RDAs. Family income or the children's body mass index (BMI) was not directly related to dietary fiber intakes. However, higher dietary fiber intakes tended to be related to higher intakes of green vegetables and fruits. Children with higher dietary fiber intake tended to prefer plant foods to animal foods. Energy and most nutrients, except heme iron and retinol, showed positive relationships with dietary fiber intake. Especially potassium and plant origin protein and calcium were highly correlated with dietary fiber intakes(r＞0.6). From these results, it is concluded that dietary fiber intakes of these sixth grade elementary school children were less than the standard reference and it is anticipated to decrease further in the future with increased incomes. Therefore, increased intakes of dietary fiber by elementary school children should be promoted through nutrition education, together with the development of cooking methods and recipes utilizing green vegetables and fruits.

The present study was aimed to examine various factors related to serum total cholesterol, triglyceride, atherogenic index, lipoperoxides and vitamin E in 174 middle-aged men residing in Taegu. Body mass index was positively correlated with serum triglyceride, and waist-hip circumference ratio was positively correlated with serum total cholesterol, triglyceride, atherogenic index and vitamin E concentration. Total cholesterol, triglyceride and atherogenic index of the subjects who smoked more than 20 cigarettes per day were significantly higher than those with smoking less or non-smokers. drinking alcohol more than 5 times per week showed higher atherogenic index than drinking less frequently of non-drinking. Subjects doing exercise had higher HDL-cholesterol level than those with no exercise. The intakes of all nutrients were above 90% of RDA and the subjects with good food habit had lower of total cholesterol, triglyceride, atherogenic index and lipoperoxides. The study indicates that avoiding heavy smoking and drinking as well as obesity and keeping regular exercise, good food habit and diversity of foods will reduce risk of cardiovascular diseases in middle-aged men.

The purpose of this study was to investigate the dietary intakes in middle-aged women(pre and postmenopausal) and relation to climacteric symptoms. We conducted the anthropometric measurements, climacteric symptoms survey, and dietary intake to assess the nutrient intakes. Also, dietary quality indices were evaluated. The subjects, over 40 years old, were 168 middle aged women(pre=74, postmenopausal=94), mean age was $48.9{\pm}3.6yr$. The anthropometric measurements showed that 59% of subjects were overweight and obese. Climacteric symptoms that were answered 'yes' in 50% plus in the subjects, were dry eyes, forgetfulness, difficult concentration, large joint pain(shoulder), fatique, backache, dry skin, joint pain(ankle and knee), dry mouth, dizziness, depression and lonesomeness, snore, morning stiffness, and hot flash. Some symptoms showed significant difference between pre and postmenopausal groups. The average energy intake was 1602.1 Kcal, which was 82% of the Korean EER. The subjects had lower vitamin A, riboflavin, folic acid, Fe, Zn and Ca intake than Korean RI. The lowest nutrient intake was Ca. The mean of food intake was 1294.2 g and MAR of diet quality indices was 0.83. In relation to dietary factors with climacteric symptoms, significant correlations have been found between total protein, animal protein, lipid, cholesterol and niacin intake and 'fatique', energy, carbohydrate, thiamin, vitamin B6, folic acid, vitamin C, Na, K and Fe intake and 'dry skin', Ca intake and 'difficult concentration'. Our results indicate that dietary factors(food and nutrients intake, INQ, NAR, MAR) may effect the prevention and reduction of some climacteric symptoms in middle aged women.

This study investigated whether social and psychological factors were related to nutritional status of the elderly. Food habits, social contacts and psychological the test score were collected from 86 institutionalized elderly women aged 65-96 in Chon-buk area. Social health status was measured by score of social contacts with others. Depression, self-esteem and locus of control were measured to evaluate psychological health status by using Zung DSI(Depression Status Intentory), Rosenberg SES(Self-esteem scale) and Rotter's vs external control, respectively. Social contacts of the total subjects were lowered, and in the group of over 85, contacts with relatives were significantly decreased compare to under 85 years of age groups. Psychological health status such as depression and self-esteem were also lowered, but locus of control showed internal control that indicates positive attitude to eating behavior. Most of the nutrients intake were positively correlated to self-esteem scores(p<0.05), but not to nutritional risk index score. Intake of vitamin C was related to social health status as well as psychological health status. Increasing the number of contact with relatives, intakes of carbohydrates, fiber, vit B1, vit C, Ca and P were elevated(p<0.05). As the score of self-esteem increased, intakes of fiber, Fe, vit B1, niacin, vit C, and vit A were increased. It is suggested that social activity and health education programs will be needed to improve the nutritional status of the institutionalized elderly.

Dietary and other factors affecting serum lipid levels of 103 rural women aged 30-76 years were assessed. Data for dietary intakes were obtained by 24-hour recall method. Body weight, height and blood pressure were measured and BMI was calculated from the anthropometric data. Serum samples were collected and analyzed for TG and lipoprotein fractions. Relation of the factors with serum lipid concentration was analyzed by Pearson's correlation coefficient(r). The results were summarized as follows: The weight, hight and BMI of the subjects were 56.8kg, 152.4cm and 24.5k/==, respectively. 31.8% of the subjects under 50 years of age($\leq$49yr group) and 61.0% of the subjects from 50 years up(==50yr group) were classified as hyperlipidemia. Most of the subjects had normal blood pressure but 8.5% were hypertensive. Total food intake of hyperlipidemic subjects was more than those of normal subjects in both age groups. Nutrients intake also tended to be higher in hyperlipidemic subjects of $\geq$50yr group. Intake of some foods like nuts, milk, or meat affected serum lipid profile even though the effects was somewhat different between two age groups. Body weight was positively related with serum TG and VLDL-cholesterol in $\leq$49yr group, and body weight as well as height and BMI affected serum lipid level in $\geq$50yr group. In summarization, it appeared that hyperlipidemia was a serious health problem in rural women. Hypertriglyceridemia due to sharp increase after 50 years old was remarkable and further research should be performed to determine the related factors in the near future.

Objectives: The purpose of this study was to investigate the blood biochemical characteristics, comorbidities, dietary intake, and other risk factors leading to poor glycated hemoglobin (HbA1c) control in elderly Korean diabetes patients over 65 years of age. Methods: Data from the 4^th (2007-2009) and the 7^th (2016-2018) Korea National Health and Nutrition Examination Surveys (KNHANES) were used. Socio-demographic characteristics (age, gender, region, household income, education level, marital status, nutrition education, diabetes duration and diabetes treatment), lifestyle characteristics (drinking, smoking, regular walking, and subjective health perception), anthropometric characteristics (height, weight, and waist circumference), blood biochemical characteristics (HbA1c, high- density lipoprotein cholesterol, triglycerides, total cholesterol, blood urea nitrogen, and blood creatinine), co-morbidities (obesity, hypertension, hypercholesterolemia, hypertriglyceridemia, and anemia), energy and nutrients intake, food group intake, and HbA1c control-related risk factors were compared. Results: Compared to the 4^th survey, the 7^th survey showed an increase in diabetes prevalence among men, an increase in the prevalence of diabetes in the older patients, and an increase in the duration of diabetes. The energy ratio from carbohydrate consumption in the 7^th survey was lower than in the 4^th. Compared to the 4^th survey, thiamine and riboflavin intake had improved, and the intakes of vitamin A, vitamin C, and niacin had worsened in the 7^th. A comparison of food group intakes showed that there was a decrease in the consumption of whole grains, potatoes, and milk and an increase in the intake of beverages and alcoholic beverages. The risk factors for poor control of HbA1c were the duration of diabetes and co-morbid hypertriglyceridemia in the 4^th survey, whereas subjective health perception, obesity, and hypercholesterolemia as co-morbidities were found to be risk factors in the 7^th in addition to the risk factors highlighted in the 4^th survey. Conclusions: For the future management of elderly Korean diabetes patients, greater care is indicated for men over 75 years, and those with low levels of education. It is necessary to increase the intake of milk and vegetables, and reduce the intake of beverages and alcoholic beverages. In addition, it is necessary to reduce the incidence of obesity, hypercholesterolemia, and hypertriglyceridemia for proper control of blood sugar.

This study examined health foods intakes and related variables among the middle aged(150 men and 159 women) in the Jeonbuk region. Health foods were classified into 4 groups including Chinese medicine(CM), toner foods(TF), vitamin or mineral supplements(VMS), and other manufactured health food supplements(MHFS). The number of people taking health foods were higher for those in their 50's than in their 40's. The consumption rate of TF in men was the highest among health foods, this result had significance. The reasons for taking health foods were recovery from fatigue, supplement of nutrients and making smooth body activity in general, but TF was used to increase of vigor. The consumption rate of health foods was a little different according to social-economic factors, namely, the consumption rate of CM was higher in people in rural than urban areas, those who graduated from middle school than university, blue color & self-employed as opposed to housewives and service workers, low level income than high level income, and Buddhism and no religion than Christian. The consumption rate had a correlation with the habits of smoking, alcohol drinking and exercise ; namely, the consumption rate of CM was higher than VMS and MHFS on smokers and alcohol drinkers. The more the frequency of exercise, the higher the consumption rate of TF, but the duration of the exercise was not correlated. This study suggests that middle aged people need nutritional education for the right recognition and selection of health foods and to consider the nature of each type of health foods.

The objective of this study was to investigate nutritional status of middle aged Korean men exhibiting impaired glucose tolerance (IGT) and identify the risk factors related to IGT Data were collected from 163 men with a fasting blood glucose level from 115 to 139mg/dl(high blood glucose group: HBG) and 170 men with a normal fasting blood glucose level(control) aged from 40 to 59 years in both groups. Weight, body mass index(BMI) and percent body fat were significantly higher in high blood glucose(HBG) group than those of control group. Age, weight, BMI, percent body fat were positively related to blood glucose. There were no differences in exercise, smoking and family history of diabetes between two groups. Frequency of fat eating and overeating of HBG were higher than those of control group but frequency of sweet snacks intake of HBG was lower than that of control group. There was no difference in daily total energy intake in two groups. Total and supper energy intakes were positively associated with blood glucose. Percent energy intake of alcohol was significantly higher in HBG group and positively related to blood glucose, however there were no difference in daily intake of nutrients in two groups. Alcohol intake was positively related to BMI, but after adjusting BMI, there was no correlation between alcohol intake and blood glucose. Serum total cholesterol and triglyceride were significantly higher in HBG group than those of control group. Serum total cholesterol i,nd triglyceride were positively related to blood glucose and high density lipoprotein cholesterol was negatively associated with blood glucose. After adjusting BMI, serum triglyceride was positively related to blood glucose. In conclusion, weight, BMI, percent body fat and blood total cholesterol, low density lipoprotein cholesterol and triglyceride levels were positively related to blood glucose level of middle aged Korean men exhibiting impaired glucose tolerance. Their eating habits exhibited higher frequency of overeating, fast eating, high energy intakes of supper. (Korean J Nutrition 33(1) : 59-67, 2000)

Variables affecting bone heath of growing children were analyzed among forty nine 10-12 year old elementary students in three rural regions of north west Chungnam area. Information on age of the parents, duration of breast feeding and birth weight were collected from the guardians of the participants and nutrient intake and diet quality were assessed by average of three-day food records of participants with the help of dietitians. Bone health status was measured by calceneal broadband ultrasound attenuation (BUA) using quantitative ultrasound (QUS). Results showed that anthropometic indexes and nutrient intake levels were not different between boys and girls. However, iron intake was significantly lower in girls than in boys. Girls after menarche showed lower intake levels for thiamin, riboflavin, pyridoxine and niacin than girls before menarche. z-scores of BMI were lower than -1 and higher than +1 showed shorter breast feeding period than others but the difference was statistically non-significant. Overall, the subjects did not consume enough s of calcium, vitamin C and folic acid. Zinc intake and BMI were the most significant factors affecting BUA by the results of backward elimination in multiple regression models. Phosphorous and beta-carotene intakes showed significant negative relation with BUA. This study showed that children living in the rural area of Chungnam need extra care to keep their health and nutrient intakes especially for the nutrients known to affect growth. Tailored nutrition education needs to be more focused on the improvement of bone health status of children.

There have been many studies indicating increased salt intake is related to elevated blood pressure (BP). Hypertension and pre-hypertension are prevalent in Korea. A national survey showed that the Korean average daily salt consumption was 12.5g, which is more than twice the current recommendation in the UK or USA. This study was performed to understand which aspects of the Korean diet contributed to high salt intake and elevated BP in Korea. The subjects consisted of 1,110 Korean adult men aged 30 to 49 years who were selected from the data of 2001 Korean National Health and Nutrition Survey, a nationwide cross sectional survey. The relationship of BP with sodium and high sodium food intakes were analyzed. After categorizing subjects according to their BP, the socio-demographic information and food and nutrients intakes were analyzed. BP increased with a larger amounts of sodium intake and the trend was significant with diastolic BP. However, the trends of BP for sodium densities of the diet were not. People with hypertension significantly tended to be older, larger, and less educated than people with normal BP. And they consumed more foods from the fats, oils & sweets group and larger amounts of discretionary sodium than normal people. The current report advocates that public health intervention, which improves the awareness of the role of salt on elevated blood pressure for the public, should be implemented in Korea.
