This study was designed to estimate mean daily iron intake and its bioavailabi- lity and to assess nutrition knowledge for 144 pregnant women in the last trimester. Serum ferritin concentration was analyzed to estimate their iron stores. Dietary intakes of iron(heme iron and nonheme iron), the amounts of MPF(meat, poultry and fish) and ascorbic acid were assessed by modified 24-hr recall method. The food frequency questionnaire was used to assess subjects usual food consumption patterns. The mean value of serum ferritin was $21.3\pm{15.2ng/ml}$ and 26.4% of the pregnant women had a serum ferritin level <12ng/ml(i.e. depleted iron stores). The mean daily intake of total orin in the pregnant women was 56.5%(17.0mg) of RDA and heme iron intake was 0.94mg which was 5.5% of total iron intake. Total absorbable iron calculated by the method of Monsen was 2.41mg and bioavailability of dietary iron was 2.41%. Food frequency test score of meats group was positively correlated(r=0.443) with the bioaavailability of dietary iron. The mean score on the nutrition knowledge test of subjects was 12.76(out of a possible 20 points). These results indicate that the nutritional iron status may be improved by increasing either the amount of iron in the diet or its availability.

This study was undertaken to investigate meal pattern, nutrition knowledge and food preference of 438 rural middle school students living in ChunNam area. As far as nutrition knowledge is concerned, most subjects did not answer correctly on the items of basic five food groups, animal fat and vegetable oil, empty source of soft drink, nutrient requirement and water's role in energy metabolism. However they responded well on the item of iron deficiency and dietary source of Ca. Male students were significantly better in the answering the items of dietary source of energy and nutrient requirement than females, while female students were significantly better on the items of water's role in energy metabolism related to obesity. Generally the respondents did neither consume oil often nor consider consumption of salty food. Furthermore, only 38.6% of subjects drink milk daily in spite of understanding dietary source of Ca, which suggested that they should incorporate nutrition knowledge into dietary behavior. The preferred foods for most subjects were fruit, kimbab and ice cream. Contrastingly the food that they did not prefer was fermented vegetable probably due to strong flavor.

This study was conducted to investigate the life style and dietary factors in high-risk of vascular diseases among workers residing in Kyungbook province. The survey was carried out on March and April, 1997 The subjects of this study consisted of fifty men aged over 30 years who were diagnosed as hypercholesterolemia(＞240mg/$m\ell$) or hypertension(＞160/95mmHg). In contrast, fifty healthy men were participated in this study as a control group. General environmental factors, nutrition knowledge and food behavior were investigated by questionaires through direct interviews with the subjects. Alcohol intake and smoking level of the subjects tended to be higher than those of the control, but not significantly different. Nutrition knowledge and food behavior scores of high-risk group were significantly lower than those of the control group. The smoking amount of subjects was negatively correlated with blood glucose and BMI. Alcohol consumption of subjects appeared to have a positive correlation with systolic blood pressure and BMI. The relationship of food behavior score with BMI and blood glucose were negatively correlated. Nutrition knowledge score showed a negative correlation with total cholesterol, blood glucose level, BMI and systolic blood pressure. These results suggest that efficient nutrition education programs need to be developed to prevent the cardiovascular diseases of workers.

The purpose of this study was to investigate dietary attitudes food behaviors and nutrition knowledge of food nutrition major and non-major female students. The subjects of this study consisted of 98 food and nutrition majors and 98 non-majors. Questionnaires were completed by them. Food and nutrition majors gave a serious consideration of taste and nutrition in selecting foods while non-majors considered taste food price amount of food and preparing time. Food and nutrition majors got higher scores in hig-her level of nutrition knowledge than non-majors and both got about the same scores in basic nutrition knowledge. The mean body weights of both were about the same and mean height of non-majors was hig-her than food and nutrition majors. Accrding to obesity index ideal body weight was more in food and nutrition ajors and underweight was more in non-majors. Dietary attitudes food behaviors and nu-trition knowledge of food and nutrition majors were better than those of non-majors. Therefore nutrition non-majors need nutrition education in order to improve their food behaviors and nutrition knowledge.

This study was conducted to evaluate the nutritional status of the elderly women, who attended the Health Promotion Program of the Seogu Health Center in Daegu. The study subjects were 158 elderly women in an urban community. The general characteristics, dietary behavior (nutritional knowledge, nutritional attitudes and dietary habits), food and nutrient intake were surveyed by an individual interview. The average age of the study subjects was 70.9 $\pm$ 2.3 years of the subject group 79.1% ranged in age from 65 to 74 years and 20.9% were over 75 years. Their average score for nutritional knowledge, nutritional attitudes and dietary habits was 7.3 (total mark of 10), 7.2 (total mark of 10) and 9.1 (total mark of 22) respectively. Specifically, the level of the dietary habits of the study subjects was very low. In relation to food group intake of the study subjects according to age, their food intake was low. The total, plant. and animal food intake were 1078.9 g, 954.4 g (88.5%), and 244.4 g (11.5%), respectively. The mean daily energy intake and nutrient intake according to percentage of the Korean RDA were higher in the from 65 to 74 year group than in those people over 75 years. The average calories and the mean percentage of nutrient intake, except for vitamin C and phosphorus. were below 75% of the Korean RDA. It seems that the nutrient intake was very low. The mean nutrient adequacy ratio (MAR) was 0.59. Nutritional status of age over 75 years old was significantly lower than that of 6574 years old group (Mar ＝ 0.60 VS 0.54, p ＜ 0.05) The correlation coefficients between their dietary behavior (nutritional knowledge, nutritional attitudes, dietary habit) and their mean nutrient adequacy ratio (MAR) showed significant linear relations. In conclusion, if nutritional education is to affect the dietary behavior of elderly women, it should be included in a Program to Promote their nutrition and health status.

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.

This study investigated the dietary behaviors and consumption of convenience foods among salaried men in Busan, Korea, and compared them based on the men's nutritional knowledge level. A questionnaire was developed based on the review of literatures and was distributed to 250 office workers in Busan in February 2013. A total of 224 data were used for the analyses. ${\chi}^2$-tests were employed for the nominal data while Mann-Whitney' U-tests were used for the ordinal data. Leven's tests were first performed before the t-tests for the interval data. Almost 60% of the respondents were female, 50% were in their 30s and 68% lived with other family members. The mean score of the nutritional knowledge test was 13.78 out of 20. Women and those who graduated from college or higher were likely to get a better score than men and those who graduated from high school or below. The respondents were divided into two groups for further analyses: Low (LK) vs. High (HK) knowledge score groups. LKs were more likely to consume 20 convenience foods than HKs. Although the respondents recognized the nutritional disadvantages of consuming convenience foods for an extended period, they continue to eat them because they lack time and further, it is quick and easy to consume convenience foods instead of preparing meals from scratch.
