Objectives: This study examined regional differences in the intake of dietary total fat and saturated fatty acid (SFA) and their food sources among Korean adults. We also investigated the associations of SFA intake with metabolic diseases by region. Methods: This study included 13,926 adults (≥ 19y) who participated in the 2016 ~ 2019 Korea National Health and Nutrition Examination Surveys. The regions were divided into urban and rural areas according to the administrative districts where the participants lived. Using dietary data obtained from a 24-h recall, intake of total fat and SFA and their food sources were assessed by region. Metabolic diseases included obesity, abdominal obesity, and elevated total cholesterol and their association with SFA intake by region were examined using multiple logistic regression. Results: Of the participants, 19.6% lived in rural areas. In urban areas, the total fat and SFA intakes were higher than in rural areas: 21.2% of energy (%E) came from total fat and 6.9%E from SFA in urban areas, whereas 18.0%E came from total fat and 5.8%E from SFA in rural areas. The percentage of participants who exceeded the dietary reference intakes for total fat and SFA in urban areas was 16.5% and 41.9%, respectively, but 43.4% of participants in rural areas showed lower intake levels for total fat compared to the reference level. Young adults did not show regional differences in fat intake, and the percentage of subjects who exceeded the reference for SFA was high both in urban (58.5%) and rural (55.7%) areas. Among middle-aged and older adults, intake of fatty acids except for n-3 fatty acid was significantly higher in urban areas than in rural areas. About 69% of older adults in rural areas showed a lower intake of total fat compared to the reference level. The food sources for total fat and SFA were meat, soybean oil, eggs, and milk in both areas. The intake of fat from eggs, milk, mayonnaise, and bread was higher in urban areas, but the intake of fat from white rice and coffee mix was higher in rural areas. The SFA intake was positively associated with elevated serum total cholesterol in urban areas (4th quartile vs. 1st quartile, OR: 1.22, 95% CI: 1.06-1.40, P for trend: 0.043), but not in rural areas. Conclusions: Regional differences in total fat and SFA intakes and their food sources were observed among Korean adults. Our findings may help plan nutritional strategies to ameliorate regional health disparities.

The purpose of this study was to find out the influence of Entrance Examinees' Eating Behavior on their health condition. The examinees for Chungbuk National university in 1992 were asked to fill out the questionnaire(The total number was 1054 ; 537 males, 517 females). The statistics used for data analysis were frequency, percentage, Crosstabs, Chi-square, t-test, one-way Anova, and Multiple Regression using SPSS/PC+ Program. The results are as follows. 1. Health condition due to an eating attitude: 1) As to health condition due to the food intake freguency, those who intaked fish or meat 3-5 days a week had the best heal th condition, but those who hardly intaked fish and meat or intaked them almost everyday had rather poor health condition. Those who intaked fried foods 1-2 days a week had the best health condition. The higher the freguency intaking such food or instant food was, the worse health condition was. 2) In view of health condition according to an eating attitude, it led to very good health condition to have breakfast & supper, to eat regularly, to select the nutritious foods, and to have a balanced diet. Overeating before sleeping and no meal or overeating before exam made their health very bad. Alcohol drinking & cigarrette smoking as favorite foods appeared significantly high in the boys. The more frequently they drinked alcohol and smoked cigarrette the worse their health condition was. Those who enjoyed milk, soya milk, and korean tea as favorite beverages had the better health condition than those who enjoyed coffee and soft drinks. 2. Influence of Eating Behavior on Health Condition. 1) The food intake freguency and the eating attitude influenced each other. The higher the score of food intake frequency was, the better the eating attitude appeared. 2) As a result of this study for eating behavior influencing on their health condition, the eating attitude influenced health condition, and the higher the eating attitude score was, the better heal th condition could be.

Because excessive consumption of sugar-sweetened beverages may reduce the quality of nutritional intake, this study examined the consumption patterns of commercial beverages, lifestyle, dietary habits, and perception of sweet taste. Participants were 407 male university students in Kyeooggido, Korea, and information was collected by self-administered questionnaire. Among them, 58 nonsmokers volunteered to participate in the taste test. Participants were divided into three groups according to the frequency of commercial beverage consumptions: 120 rare (< 1 serving/week), 227 moderate (1-3 servings/week) and 133 frequent (> 3 servings/week) consumption groups. More subjects from the rare consumption group chose water, tea, and soy milk, and more from the frequent consumption group chose carbonated soft drinks and coffee (P=0.031) as their favorite drinks. Frequent consumption group consumed fruit juice, coffee, and sports and carbonated soft drinks significantly more often (P=0.002, P=0.000, P=0.000, respectively), but not milk and tea. Frequent consumption group consumed beverages casually without a specific occasion (P=0.000) than rare consumption group. Frequent drinking of commercial beverages was associated with frequent snacking (P=0.002), meal skipping (P=0.006), eating out (P=0.003), eating delivered foods (P=0.000), processed foods (P=0.001), and sweets (P=0.002), and drinking alcoholic beverages (P=0.029). Frequent consumption group tended to have a higher threshold of sweet taste without reaching statistical significance. The results provide information for developing strategies for evidence-based nutrition education program focusing on reducing consumption of unnecessary sugar-sweetened commercial beverages.

Dietary pattern analysis is important complementary approach for identifying associations between diet and chronic disease. A case-control study was conducted in order to examine dietary patterns and the risk of colon cancer in Korea. Data were collected from both 137 cases with either colorectal cancer or large bowl adenomatous polyps and 134 controls regarding social-demographic characteristics and food intake using a semi-quantitative food frequency questionnaire. We conducted factor analysis and identified 6 major dietary patterns: 'Well-being diet' characterized by higher intakes of potatoes, yogurt, soybean paste and vegetables, 'Meat & fish', 'Milk & juice', 'Pork & alcohol', 'Rice & kimchi', and 'Coffee & cake'. We calculated factor scores for each participant and examined the associations between dietary patterns and colon cancer risk. After adjusting for potential confounders, there was a relative risk for colon cancer of 0.16 (95% confidence interval, 0.07 - 0.34) when comparing the highest with the lowest tertile of the 'Well-being' pattern. Significant trends of decreasing risk of colon cancer also emerged with the 'Milk & juice' (OR = 0.40, 95% CI = 0.20 - 0.79). In contrast, inverse associations of the risk were found for 'Pork & alcohol' (OR = 1.92, 95% CI = 0.93 - 3.97), 'Coffee & cake' (OR = 2.18, 95% CI = 1.07 - 4.46). For the 'Meat & fish' pattern, the decreased risk of colon cancer was observed in the second tertile, but not in the highest tertile when comparing to the lowest. The 'Rice & kimchi' pattern had a nonsignificant association with the risk. These data suggest that major dietary patterns derived from the FFQ associated with the risk of colon cancer in Korea. Since foods are not consumed in isolation, dietary pattern research in natural eating behavior may be useful for understanding dietary causes of colon cancer.

Objectives: The valid assessment of food and nutrients intakes using appropriate dietary intake method is necessary to improve the nutritional status of the hemodialysis (HD) patients. This study was conducted to compare the method between newly developed, semi-quantitative food frequency questionnaire (Semi-FFQ) and 7-day dietary records (7-DRs) for hemodialysis patients. Methods: We conducted both methods on 53 maintenance HD patients in two university hospitals. We calibrated the frequency, portion size and daily intake of 47 food items reported in Semi-FFQ. The food and nutrients intake was compared and the correlation of the two methods was analyzed. Also each nutrient intake was compared to recommended dietary allowance for Korean (KDRIs) and recommended nutrient reference value for HD patients. Results: Energy and energy-yielding nutrients intakes were significantly higher in the two methods (p<0.01). These support the possible reliability between Semi-FFQ and 7-DRs that is similar with regard to most mineral and vitamin intakes. Thus, the Semi-FFQ used in this study for the assessment of nutrient intakes of HD patients can be reliable for the assessment of the nutrient intake along with the 7-DRs. The correlation coefficients were higher for foods consumed daily, such as steamed rice, meat and chicken, bean, egg, milk, coffee and alcohol than for those of foods eaten rarely (p<0.01). Conclusions: The Semi-FFQ used in this study can be a reliable tool for the assessment of the HD patients' nutrient intake along with the 7-DRs, despite its limitations.

The purpose of this study is to investigate the food habits and the dietary intake of female college students at day and night class in the Kyunggido area. The questionnaires were collected from 294 students(151 day class and 143 night class students) out of 350 in total. The results are as follows: Breakfast for day class students and breakfast and dinner of night class students were skipped more than 3 times a week. The main reason was short of time. In the behavior of food intake, the frequency of yellow-green vegetables, milk and seaweeds intake was low in all respondents. 18.4% of night class students ate out 3 times a day. In the kind of menu for eating out, Korean food was the most frequent. snack food the second, and fast food came last. 23.9% of students ate something 2 or 3 times a day between meals. The main reason for eating between meals was the desire to eat for day class students, and hunger for the night time students. Consumption of coffee was 0.76 cup a day Daily mean of calory intake was 1.394 kcal and the ratio of carbohydrate. protein lipid was 61:14:25. The intakes of iron and niacin of the day class students were higher than those of night class students. There was no significant difference in intake of other nutrients between day and night class students. Intake of calcium and iron did not reach 50% of Korean RDA.

Interviews of 208 women concerning dietary changes during pregnancy were under-rtaken from September 1986 to January 1987 at the medical centers in Seoul and Kyung Ki. 84% of the total subjects felt the morning sicksnes such as nausea and vomiting within the first trimester of pregnancy. There was a significant correlation between the experience of moring sickness and some environmental factors such as school carreer, food intake in early pregnancy, the number of meals and taking of medicines for promoting nutrition. Foods for which specifie cravings were frequently cited were fruits, meats, cold noodle, noodle and chinese food. Foods of aversions were Kimchi, meats, fish and fatted foods. With regard to beverage, there were the increase in milk and fruint juices consumption and the decrease in coffee ingestion during early pregnancy primarily attributed the concern for feto-maternal health. Possible explanation for these changes associated with pregnancy discussed.

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.

This study was carried out to identify the Important modifiable risk factors for reduced bone mass and to construct prediction model which can classify women with either low or high bone mass. Through the literature review, individual characteristics such as age, body weight, height, education level, family history, age of menarche, postmenopausal period, gravity, parity, menopausal status, and breast feeding period were identified and factors of life style such as past milk consumption, past physical activity, present daily activity, present calcium intake, alcohol intake, cigarette smoking, coffee consumption were identified as influencing factors of reduced bone mass in women. Four hundred and eighty women aged between 28 and 76 who had given measurement bone mineral density by dual energy x-ray absortiometry in lumbar vertebrae and femur from July to October, 1997 at 4 general hospitals in Seoul and Pusan were selected for this study. Women were excluded if they had a history of any chronic illness such as rheumatoid arthritis, diabetes mellitus, hyperthroidism, & gastrointestinal disorder and any medication such as calcium supplements, calcitonin, estrogen, thyroxine, antacids, & corticosteroids known affect bone. As a result of these exclusion criteria, four hundred and seventeen women were used for analysis. Multiple logistic regression model was developed for estimating the likelihood of the presence or absence of reduced bone mass. A SAS procedure was used to estimate risk factor coefficient. The results are as follows For lumbar spine, the variables significant were age, body weight, menopause status, daily activity, past milk consumption, and past physical activity(p<0.01), while for femoral Ward's triangle, age, body weight, level of education, past milk consumption, past physical activity(p<0.001). Past physical activity, present daily activity and past milk consumption are the most powerful modifiable predictors in vertebrae and femur among the predictors. When the model performance was evaluated by comparing the observed outcome with predicted outcome, the model correctly identified 74.1% of persons with reduced bone mass and 84.5% of persons with normal bone mass in the lumbar vertebrae and 82.9% of persons with reduced bone mass and 75.0% of persons with normal bone mass in the femoral Ward's triangle. On the basis of these results, a number of recommendations for the management of reduced bone mass may be made : First, those woman who are classified as high risk group of the reduced bone mass in the prediction model should examine the bone mineral density to further examine the usefulness of this model. Second, the optimal amount of milk consumption and a regular weight bearing exercise in childhood, adolescence, and early adult should be ensured.

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.
