  • We aimed to evaluate the effect of nutrition education program on nutrition knowledge, dietary behavior, dietary intakes and anthropometric parameters in primary school children. Eighty five 4th grade children (boys = 43, girls = 42) were enrolled in the intervention program for 5 months. The subjects were asked to fill out a questionnaire about nutrition knowledge and dietary behavior two times, at the baseline and after completion of the program. Dietary intake information was collected from participants using a 3-day food record and their anthropometric parameters were measured. Upon completion of the intervention program, both nutrition knowledge and dietary behavior scores were significantly improved in all subjects. Energy intake was increased from 1,571.9 kcal to 1,734.1 kcal with significant improvements in nutrient density for protein, Ca, P, K, vitamin A and niacin. While subjects' height, weight, lean body mass and soft lean mass were significantly increased during the program, significant decreases were observed in the rohrer index, percent body fat, waist-hip ratio and body fat mass. The changes in nutrition knowledge scores were positively correlated with the changes in dietary behavior scores, micronutrient intakes and anthropometric parameters. These results indicate that enhancement of nutrition knowledge through well-planned long-term nutrition education program is effective not only for the improvement of dietary behaviors and dietary intakes but also for the positive changes in anthropometric parameters among primary school children.

  • Objectives: This study was conducted to examine the effects of nutrition education with a dietary guidebook for children on dietary attitude, nutrition knowledge and nutrient intakes. Methods: The subjects were 54 higher grade elementary students (27 educated vs. 27 non-educated). The educated group was provided individual and/or group lessons (40 min/lesson/week, 4 week) using a dietary guidebook of Children developed by The Korean Society of Community Nutrition (KSCN) & Korean Food and Drug Administration (KFDA). The contents were Balanced Diet, Smart Food Choices, Cooking a Healthy Snack and Building a Healthy Body. We examined the differences in nutrition knowledge, dietary attitudes and dietary intake between the educated group and non-educated group. Results: After education, the educated group improved dietary attitude, nutrition knowledge and qualitative nutrient intakes compared to the non-educated group. Specifically, among dietary attitudes, 'taking a meal with salty and spicy food' increased, while among nutrition knowledge, 'functions of protein', 'functions of fat', 'foods with carbohydrates', 'foods with fat', 'foods with vitamins', and 'foods with minerals' were increased. Nutrition adequacy ratio (NAR) scores for vitamin C, iron, and zinc were increased. Conclusions: Nutrition education using a dietary guidebook for children developed by the KSCN & KFDA had positive effects on nutrition knowledge and qualitative nutrient intakes. These findings suggest that nutrition education focused on personalized daily energy and nutrient requirements may improve dietary attitude and quantitative nutrient intakes of children.

  • This study was designed to investigate the effect of the ratio of energy from carbohydrate to total calories on dietary intake, obesity index, blood pressure, and blood lipid content in cardiovascular disease patients over 35 years old. A total of 552(227 male, 325 female) subjects were divided into three groups according to carbohydrate/total energy ratio : carbohydrate ratios below 25 percent were in the low carbohydrate group( <61.1%), between 25 and 75 percent carbohydrate were medium($\geq$61.1-<74.7%), and higher than 75 percent were in the high carbohydrate group($\geq$74.7%). The anthropometric data, nutrient intake, serum lipid levels, and blood pressure of each group were compared with one another. For men and women with high carbohydrate intakes, Inadequate nutritional intake was observed. Abdominal fat accumulation and blood TC level for men in the high carbohydrate group were higher than in medium or low carbohydrate groups. Therefore, it seems that high carbohydrate intake may produce adverse effects on abdominal fat accumulation and blood lipid patterns. Blood pressure, however, was significantly higher for women in low and high carbohydrate groups than in medium carbohydrate group. These results suggest that extremely high and low carbohydrate intake may raise the risk of cardiovascular disease and that it is necessary to consume nutritionally balanced meals. This can be done by controlling the ratio of dietary carbohydrate at a medium level in order to prevent and/or to reduce the risk.

  • Recently, it appears to have a trend of adult having weight increase in Korea. The number of obese people is increasing in Korea due to the changes of meal pattern and the lack of physical activities. Currently, obesity is the prevalent health problem in the world. The purpose of this study was to investigate the effect of mulberry leaf-Jeolpyun on the serum lipids of overweighted male university students. After 3 days of education and adaptation on this study, twenty male university students with 20.9yrs old average were fed a uniformed dormitory foodservice, and they ate constant amount of 9% mulberry leaves added-rice cake, Jeolpyun(100g) instead of boiled rice(l00g) , on each meal. Experiment was conducted during 14 days period. All meals were provided promptly. and the subejects were required to have breakfast, lunch, and dinner on weekdays. Mean height, weight, and BMI were 176.55cm, 90.OOkg, and 28.73, respectively. Although it was not very significant, body weight of the subjects appeared to be reduced after consuming the 100g substitute diet of mulberry leaf-Jeolpyun. Daily energy Intake of the subjects was 2,360.6kcal, which represents 94% of the Korean RDA. The ratio of energy obtained from carbohydrate, protein, and fat was 55: 17'27 As compared with the Korean RDA, 65 : 15 20, carbohydrate consumption was decreased but protein and fat consumption was a little bit increased. The ratio of animal-protein source was 58%, and animal-fat intake was 42%. Triglyceride concentrations decreased. but HDL-cholesterol was in the reversed manner The concentrations of HDL-cholesterol increased significantly after the 2wk-lOOg subtitute diet of mulberry leaf-Jeolpyun (p<0.05) . However, there were no significant differences in total cholesterol and LDL-cholesterol con concentrations .

  • This study was designed to study sources of variability(subjects, day by day, season, day of week, sequence, number of repeated days, compliance etc.) in multiple 24-hour dietary recall method. Dietary intakes of college women in Seoul were obtained using 24-hour dietary recalls, consecutive 7 days, 4 times for 1 year. The result of this study shows that 1) the reproducibility of multiple 24-hour recalls is low(intraclass correlation coefficient<0.3), 2) the intraindividual variations of all nutrients are more than 80%, 3) the major components of variation are interindividual vriability and intraindividual variability(within person variability and methodologic error). There were small but statistically significant season and compliance effects. 4) the ratio within-person varation to between-person variation for absolute and transformed nutrient intakes except some nutrients such as vitamin A, vitamin C, energy from protein and fat etc, was less than 1.7 the minimum numbers of days needed in 24-hour dietary recalls to estimate usual intake for this group were 1 to 21 days. And the numbers of days needed to get the usual intake of an individual varied among individuals and within individuals for different nutrients, ranged from 1 days for log carbohydrate(% energy) to 470 days for Na. 6) There were greater than 0.7 correlation coefficients between the average nutrient intakes of 12 days and intakes of 28 days. Therefore, it was desirable to take the 24-hour recall more than 12 times, repeating 3 days every season.

  • This study investigated the effects of the nutrition education and exercise program on body composition, dietary intakes and physical fitness in obese women. The subjects were 44 obese women (BMI${\geq}$ 25 kg/$m^2$) who had been participating in nutrition education (1 time/week) and exercise program (3 time/week) for 12 weeks. Nutrition education was focused on low energy, high protein and low carbohydrate diet to reduce the body weight and improve the diet quality. To evaluate the effectiveness of the program, daily nutrient intakes were assessed by 24-hour recall method. Body composition, blood lipid profiles and physical fitness test were assessed before and after the intervention. After the intervention, body weight, BMI, percent body fat, soft lean mass and waist/hip ratio were significantly decreased (p < 0.001). Fasting blood sucrose, total cholesterol, LDL-cholesterol and atherogenic index (AI) were significantly decreased (p < 0.001), while HDLcholesterol was significantly increased (p < 0.001). Energy adjusted protein, fiber, vitamin A, vitamin $B_2$, vitamin $B_6$, vitamin C, vitamin E, niacin and folate were significantly increased. After the intervention, the muscle endurance, muscle strength, agility, balance were significantly increased. The changes in obesity indices (body weight, BMI, percent body fat, waist-hip ratio) were correlated with the changes of the nutrient intakes, serum lipid profiles, physical fitness. These results show that nutrition education and exercise program was effective not only for weight reduction but also for the improvement of physical strength and cardiovascular disease risk factors in obese women.

  • This study was performed to investigate the dietary attitudes and nutrient intakes of nurses. A total of 291 nurses working at hospitals in the Kyungnam area participated in the study. The general characteristics and dietary attitudes of the subjects were surveyed using a self-administered questionnaire, and nutrient intakes was examined using one-day 24-hour recall method. The results were as follows : 67.7 percent of the subjects were nurses, 32.3% were nursing assistants. Average age of the subjects was 26.9 years old, average nursing experience was 5.7 years, and 70.7% of the subjects graduated from junior college. The rates of shift work (45.4%) and non-shift work (54.6%) were similar, and 91.5% of subjects worked on a three-shift a day schedule. The average nutrition knowledge score was 14.3 $\pm$ 2.5 out of a possible 20 points. Most of the nurses had experienced dietary problems such as skipping meals and overeating. Sixty-eight point three percent of the nurses had breakfast less than 3 times a week, and the main reason for skipping meals was a lack of time. Most of the nurses (74.1%) didn't exercise regularly. The average score on dietary habits was 55.6 out of 100, and most of the subjects belonged to the‘fair’group in terms of dietary habits. Married nurses, and those over 31 years of age, scored significantly higher on dietary habits than unmarried nurses, and those under 25 years of age (p < 0.001), and the scores significantly increased with increasing age. Mean daily carbohydrate and fat intake was 231.5 $\pm$ 66.1 g, 41.1 $\pm$ 18.8 g, and cholesterol and crude fiber intake was 238.2 $\pm$ 184.6 mg, 5.2 $\pm$ 2.0 g. respectively. Compared with the recommended allowances, the energy (1560.0 $\pm$ 448.5 kcal), calcium (453.8 $\pm$ 222.3 mg) iron (10.6 $\pm$ 7.6 mg), vitamin A (658.5 $\pm$ 538.1 R.E) and vitamin B$_2$ (0.96 $\pm$ 0.5 mg) figures were below the Korean RDA, and the protein (65.9 $\pm$ 31.0 g), vitamin B, (1.14 $\pm$ 0.5 mg), vitamin C (143.2 $\pm$ 119.6 mg), niacin (14.4 $\pm$ 6.3 mg) and phosphorus (958.1 $\pm$ 352.1 mg) figures were above the Korean RDA. The average carbohydrate, protein, fat ratio of energy intake was 60:17:23. The intake ratio of Ca and P showed an unbalance of 1:2. The dietary habits had a positive correlation (p < 0.001) with nutrition intake except vitamin A and vitamin C. Therefore, In order to improve overall dietary behavior and nutritional status, systematic nutrition education programs should be developed.

  • 경기지역 일부 대학생의 지방제한식에 대한 행동단계 분포는 연구대상자의 19.3%가 자각이전, 13.8%는 자각, 31.1%는 준비, 28.7%는 실시, 7.1%는 유지단계로, 성인보다 실시 및 유지 단계 비율이 낮아 대학생의 지방질을 선호하는 식생활을 엿볼 수 있었다. 행동변화 단계별로 BMI, 자신의 건강평가, 음주, 흡연 등은 차이가 없었으나 성별에 의한 차이는 뚜렷하여 남학생은 자각이전 및 자각단계가, 여학생은 준비, 실행 및 유지단계의 비율이 많았다. 식행동 단계의 주요 예측인자인 자아효능감은 자각이전에서 유지단계로 갈수록 증가하였다. 열량, 지방질, 포화지방산, linoleic acid($\omega$6), 콜레스테롤 섭취량은 남여 모두 자각이전과 준비단계에서 많고, 실행과 유지단계에서 적었다. 섭취열량중 지방질의 비율은 자각이전과 준비단계에는 권장수준인 20%를 크게 상회하였으나, 실행과 유지단계에서는 권장수준을 섭취하는 양호한 식습관을 갖고 있었다. 섭취 지방산의 P/S 비율은 모두 권장비율에 속하였으며, $\omega$6/$\omega$3 비율은 여학생은 권장범위에 속하였으나(자각이전단계 예외), 남학생은 모든 단계에서 권장범위 이상으로, 지방질의 질적 영양문제가 지적되었다. 행동단계별 영양소 섭취량의 차이는 여학생에게서 더 뚜렷하였으며 , 남학생은 실행단계보다 유지단계에서 열량, 포화지방산, 콜레스테롤 섭취량, $\omega$6/$\omega$3 비율 등이 오히려 증가하는 경향을 보여, 행동변화 모형 에 의한 대상자의 구분은 여학생에서 더 유용한 도구였다. 남학생의 열량, 지방질, 단백질 섭취량은 저녁식사에서만 행동단계별로 차이를 보였으나, 여학생은 저녁을 포함한 다른 끼니에서도 차이를 보여, 남학생보다 단계별 식행동의 차이가 뚜렷하였다. 이상의 결과에서와 같이 아주 간단한 과정을 통해 식행동 단계를 구분지어 주는 행동변화단계 모형은 대상자의 특성과 지방질 영양의 문제점을 파악할 수 있게 되어 각 개인별 맞춤 영양교육의 한 도구가 되어질 수 있음을 알 수 있었다. 따라서 본 행동변화단계 모형에서 자각이전, 자각, 준비 단계로 분류된 대상자들에게는 양적, 질적으로 모두 양호한 지방질의 섭취 패턴을 보이는 실행과 유지 단계가 되도록, 자아효능감 등을 증가시키는 영양교육이 이루어져야 할 것이다. 또한 남학생의 경우 여학생보다 지방제한식을 실시하는 비율이 적었으며, 행동변화 단계에 따라 영양소 섭취량의 차이도 뚜렷하지 않아, 이들을 위한 영양교육의 필요성이 지적되었다. 따라서 이들에게 구체적인 내용의 영양교육을 실시하기 위해, 열량과 지방질, 포화지방, 콜레스테롤 섭취량의 주요 급원식품에 대한 후속 연구가 이루어져야 할 것으로 생각된다.
