Objectives : The aim of this study was to investigate the relationship between the contributions of macronutrients to the total energy intakes and Body Mass Indices (BMI, $kg/m^2$) of Korean women. Methods : We used dietary records data from 115 healthy Korean women, ages 20 and over, who completed four 3-day dietary records between February 2003 and March 2004. For the calculation of nutrients we used a dietary assessment program developed by the Korean Nutritional Society. Macronutrient intakes were estimated by averaging individual total daily intakes in four 3-day dietary records. Subjects were categorized into three Body Mass Index (BMI) groups : underweight (BMI < 20), normal (20 $\leq$ BMI < 25), and overweight (BMI $\geq$ 25) group. Results : The total energy intakes were not different among the three BMI groups. Similarly, other macronutrient intakes such as protein, fat, carbohydrate, vegetable protein, animal protein, saturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids were not different. From the multivariate nutrient density model, substituting polyunsaturated fatty acid for carbohydrate was positively associated with BMI in women aged 20 to 49 ($\beta=2.31$, p<0.01). In women aged 50 and over, substituting animal protein for carbohydrate was positively associated with BMI ($\beta=0.549$, p=0.04). Conclusions : No single macronutrient was associated with BMI when all subjects were combined. However, when stratified by age, polyunsaturated fatty acid intake in younger women, and animal protein intake in older women, were positively associated with BMI. In the future, we recommend a larger study to confirm these results.

Nutrition during childhood is essential for growth and maintenance of health. Good food habits developed during the childhood will contribute both to the healthy growth and the prevention of the degenerative disease of later life. Both parents and the providers in child care centers play an important role for children's good eating behavior. Therefore all child care programs should achieve recommended standards for meeting children's nutritional and educational needs in a safe, sanitary, and supportive environment to promote the healthy growth and development of children. The purposes of this study were to evaluate the foodservice management practices and assess the needs for a Central Production Unit by contacting the child care center' providers. This approach was achieved using a variety of qualitative and quantitative information including the general foodservice management practices and the needs for a Central Production Unit. An indepth face-to-face interview with structured-questionnaires was undertaken at 32 representative child-care centers in Seoul. Statistical data analysis was done using the SAS program for descriptive analysis and ANOVA. The number of national/public and private sectors were 11 respectively, followed by 10 licensed home day-care centers. Total average number of children in child-care centers was 54.3 $\pm$48.5. The foodservice productivity index in child-care centers was 4.8 minutes per meal for public child care centers, 6.0 for private child-care centers, and 9.8 for home child care centers. Home child care centers were found to have the lowest productivity index which indicated inefficient foodservice practice. The important factors in group purchasing were menus(39.6%) or close distance(39.6%) > type of foodservice operation(32.8%) > total number of meals(19.9%) > food costs(16.2%) in order. Average score of the efficiency for central food production in child-care centers was 3.80 $\pm$0.84 out of 5.

The purpose of this study was to analyze the importance-performance of clinical nutrition management in convalescent hospitals. The research was carried out based on questionnaires administered from March to April, 2015 to 73 dietitians at 40 convalescent hospitals in the Gyeongnam area. There was a statistically significant difference between the mean scores for importance (4.01/5.00) and performance (2.95/5.00) of clinical nutrition management. The importance and performance grid analysis showed that participation in a nutritional management committee, administration of patients using a cooperation program among hospital departments, cooperation with a medical team on patient's nutrition status, nutrition initial assessment, nutrition care process for patients showing malnutrition, nutrition care process for tube feeding patients, management of a therapeutic diet, meal management using dietary slip instructions including a therapeutic diet, and explication of a therapeutic diet for patients scored high regarding importance and performance (doing great area). Medical records on patient's nutrition management, and nutrition counseling for requested patient scored low regarding the importance and high regarding performance (overdone area). Participation in medical rounds, personal nutrition education for patients, group nutrition education for patients, nutrition education for medical teams, development of a menu for therapeutic diet and standardized recipes, and provision of information on diet therapy for patients after discharge scored low regarding importance and performance (low priority area). Accreditation of convalescent hospitals and interest of medical professionals in clinical nutrition management were effective variables for the importance-performance gap of clinical nutrition management. In conclusion, the accreditation process and positive awareness of medical professionals with regard to clinical nutrition management had positive effects on reduction of the importance-performance gap in clinical nutrition management at convalescent hospitals. The strength of clinical nutrition management in the accreditation and development of an education program for increasing medical team or administrator interest in clinical nutrition management could lead to improvement of clinical nutrition management for elderly patients in convalescent hospitals.

Health can be maintained and promoted by pursuing a healthy lifestyle. A healthy lifestyle implies keeping healthy habits such as regular exercise, a balanced diet, weight control, and stress management etc. The objectives of this study are: (1) To find out patterns in the lifestyle and health status of high school students. (2) To analyze the factors that affect a healthy lifestyle. (3) To compare the level of understanding of a healthy lifestyle and its practice between male students and female students. The study population wag 388 high school students. The data was analysed through a % total, a $X^2$ test, and a multiple classification analysis. The lifestyle assessment questionnaire was devided into ten sections. The results are as follows; (1) There was a positive correlation between health status and a healthy lifestyle. (2) There existed strong positive correlations between independent variables (age, group) and dependent variable (nutritional practices, physical activity, stress management, serve of purpose). (3) The level of understanding of a healthy lifestyle was not high for most of the students. Female students showed a higher understanding than male students in nutrition practice, while male students group showed a higher and under standing than female students for physical activity. The other result were similar in their practice of a healthy lifestyle. With all these above considerations, the level of understanding and practice of a healthy lifestyle in students was not higher than the adult group. Students should have more educational opportunities and take a more systematic education in practicing a healthy lifestyle.

This study developed a vegetable preference increase program that can be applied at the Center for Children's Foodservice Management (CCFM) for children in child-care facilities and kindergarten and the training performance was evaluated by 192 5-year old children. Teachers considered 'disliked food' ($3.23{\pm}0.85/out$ of 5) as the most serious nutritional problem and typical disliked food was 'vegetables' (54.2%). Based on this finding, to increase the preference for vegetables, a five-phase education program was developed. In this program, each phase was composed of activities to increase children's interest in vegetables by using each sense out of the five senses. Center dieticians had visited and conducted the program in 12 facilities. By using an illustration assessment tool, the training performance was evaluated by comparing the children's knowledge level and their preference changes in vegetables. Consequently, as examined by 10 questions on the knowledge of vegetables, trained children's (in total 192) knowledge of vegetables had considerably increased (p<0.01, p<0.001), and their preference for 15 out of the 16 vegetables, except for carrots, also showed a considerable preference increase after the training (p<0.01, p<0.001). Therefore, this program is considered to have contributed to reducing disliked vegetable eating behaviors.

The purpose of this study was to identify the differences in dietary consumption patterns according to the exercise level of Korean adults. The study subjects were the 7,370 Koreans aged 20 years and older of the 1998 Korean Health and Nutrition Survey. The dietary assessment was conducted by means of the 24 hour recall method. Data for individual exercise behavior were collected by interviews as part of the National Health Behavior Survey. Following the analysis of variances the Duncan＇s Multiple Range Test was used to test the differences in food and nutrient intakes among groups with different levels of exercise. Current exercise practices were reported by 22% of the male subjects and 15% of the female subjects. Unlike observations from the American and European studies, a greater amount of meat intake was observed more frequently among high exercises group than among middle and low exercisers in the case of the male subjects. This was reflected in the increasing levels of protein and fat intake in proportion to the exercise levels. However, the food and nutrient intake patterns of female exercisers were quite different from those of the males. The least intake of fatty foods was observed among the high exercisers. Energy intake from fat was the lowest among the high exercisers. These results may imply that the motivation to exercise was quite different between male and female Koreans. This dietary pattern may have a risk of undernution. Summerizing the results, whatever the motivation of the exercise, the Korean exercisers of both sexes had unhealthy dietary pattern. Therefore, nutritional education should be conducted to encourage the eating of a balanced diet along with exercise, among Koreans of both sexes, in order to promote a healthy lifestyle.

Purpose: The purpose of the study was to evaluate the accuracy of two different fluid intake measurement methods (fluid only vs. all dietary intake) in measuring fluid balance compared to body weight change among patients with cancers. Methods: A total of 60 cancer patients in an urban cancer center in South Korea participated in the study. Adult patients who were over 18 years old; having 24-hour I&O order; and taking either normal regular diet or soft blend diet were included. Demographic information and disease related information were also gathered. The data were analyzed using SPSS 18.0 program. Results: Measuring 'fluid only' for oral intake was a more accurate measure than measuring 'all dietary intake' (p=.026 vs. p=.094). Both methods had positive correlations with the amount of weight change (r=.329, p=.010; r=.303, p=.019). Measuring body weight was a more accurate and efficient way of evaluating the fluid balance than 24 hour cumulative I&O. Conclusion: Developing clinical manual for selecting proper patients who needs fluid balance monitoring is imperative. Administering weight check and/or 24 hour cumulative I&O should be considered thoroughly based on solid nursing evidence in future.

This study was conducted to evaluate nutritional status of Korean women of child-bearing age. A comparison was made between 113 non-pregnant and 200 pregnant women. Pregnant women of 24-28 weeks of gestation were recruited from prenatal clinic in Seoul. Nonpregnant women were included college students, nurses, office employers, and sales women. General characteristics, anthropometric measurements, dietary intakes, and hematological values were assessed. There was no difference in mean BMI for nonpregnant and pregnant (pre-gravid) women, which were 20.2 kg/m$^2$and 20.6 kg/m$^2$respectively. The pregnant women showed a tendency of better health-caring behavior, evidenced by stop smoking and drinking, and in taking nutrient supplements. The mean intakes of energy, vitamin A, vitamin B$_2$, calcium, and iron did not meet Korean RDA for adult women. In particular, calcium and iron intakes of both nonpregnant and pregnant women were under 60% of the Korean RDA. Judging by MDA score, dietary quality was better in pregnant than in nonpregnant women. Mean serum values of albumin, total cholesterol, LDL-cholesterol, HDL-cholesterol, Hb, IgA, IgG were in normal range. However, more than 13% of the nonpregnant subjects showed mild hypercholesterolemia (cholesterol > 200 mg/dl) and anemia (Hb < 12.0 g/dl) . The percentage of anemia in pregnant women were much higher; the subject with Hb < 11.0 g/dl were approximately 30%. The pregnant subjects showed significantly higher serum concentrations of triglycerides and cholesterol, and significantly lower concentrations of albumin, IgA, and IgG compared to nonpregnant women. Correlation analysis showed that Hb concentrations were correlated with the intakes of iron- and protein- containing foods such as meat and vegetables. This study strongly suggest that iron-deficient anemia is a major nutrition problem in Korean child-bearing women and this condition is correlated with dietary intakes.

In Korea, the school foodservice program has been expanding rapidly in recent years, partly as a result of increased government support. With the growth in the number of schools offering foodservice programs, food safety and sanitation concerns have been increasing. To assist with program improvement, a situation analysis was carried out, with the focus on equipment and sanitary management of school foodservice programs under flour different management systems. A questionnaire was mailed to the foodservice directors of 234 randomly selected schools chi[h included elementary, middle and high schools at the national level. Among them, one hundred and sixty-five responses reasonably completed were used for the analysis. This study classified each school's foodservice management into one of four types : independent-conventional, independent-commissary, contract-conventional, and contract-delivery. The results show that the monitoring of employees' health and personal hygiene, and employees' sanitary education was well conducted, but that the sanitary education of the voluntary parent workers was largely ignored. Eighty-six percent of the schools had their drinking water tested for sanitation, and the results showed that more effort is needed in careful management of drinking water in order to prevent foodborne illnesses and bacillary dysentery. In general, contract management showed lower scores in foodservice equipment and their efficiency, compared with independent management. A relatively high number of schools on the contract-delivery management system employed nurses and leachers instead of dietitians and foodservice directors. The adoption of the HACCP (Hazard Analysis Critical Control Point) system was lowest in contract-conventional and contract-delivery management systems, and highest in elementary schools using the independent-conventional system.

Hypertension is prevalent among older adults, and nutrition is important for hypertension management. However, there are few nutrition education materials developed for older adults. The purpose of this study was to develop a booklet for prevention and management of hypertension for older adults. Based on lesson plans, topics for the booklet included introduction to hypertension, hypertension prevention through weight management, nutritional management of hypertension, and lifestyle modifications. After several revisions of the draft were made, illustrations and icons appropriate to the text were designed by a graphic designer using Illustrator 9.0 and Photoshop 6.0. The booklet consisted of four chapters and 40 pages. The first chapter dealt with information on hypertension, risk factors, complications and dietary guidelines. These were mainly explained by illustrations and characters of older adults. The second chapter included assessment of obesity, reducing fat intake and behavioral change strategies. The third chapter focused on practical tips for reducing salt, eating more fiber and calcium, and sample menus. The fourth chapter presented information for quitting smoking and drinking, and stress management. Finally, games, meal planning and quizes, were presented as reinforcement. Based on pilot testing with 10 adults aged 50 and older, minor changes were made in wording, expressions and information. This booklet is characterized by using simple and specific messages, providing tips for dietary and lifestyle changes, and using illustrations and characters of older adults to increase understanding. The revised booklet is self-explanatory and can be used by older adults or in nutrition education for older adults.
