We investigated the role of fatty acid availability on skeletal muscle AMPK activity and adenine nucleotide content. To investigate the chronic effects of elevated fatty acid in vivo Sprague-Dawley rats were fed a chow diet (15% fat) or a diet high in saturated (SAFA, 52% fat) or polyunsaturated (PUFA, 52% fat) fat for eight weeks. High fat diets increased (P < 0.05) plasma FFA levels by 25%. AMPK activity was increased in SAFA and PUFA rats and occurred in the absence of changes in ATP, AMP, phosphocreatine and glycogen content. These results suggest that increasing fatty acid availability increases AMPK activity independent of changes in the cellular energy charge, and implicate the regulation of AMPK by a covalent mechanism. These data also support the contention that increasing fatty acid availability can increase subsequent fatty acid oxidation by an AMPK-mediated process.

This study was conducted to provide current information on dietary behaviors and dish preferences of elementary school children and to suggest guidelines for proper dietary behaviors. To accomplish study objectives survey was executed using the questionnaire for 420 fifth and sixth grade school children, chosen from schools in Kangwha-gun and East River District of Seoul. A questionnaire largely consists of categories including general characteristics, dietary behavior and preferences of the subjects for some dishes. Results showed 30％ of the subjects had breakfast irregularly. A majority of the subjects took Korean style dishes of cooked rice and soup for breakfast. fifty-eight percent of subjects had a regular meal time. Imbalanced diet(avoiding specific flood group thereby causing unbalance in nutrient intake) habit group was estimated to be 47.3%. Twenty one percent had a habit of overeating. In choosing the snack, taste was considered to be a more important factor than nutrition. Advertisement of the snack was shown to be one of the Important factors in selecting the snack. The girls were more concerned about weight control than the boys. Also the girls were likely to rely on the diet to control weight since they exercised only in the physical c1ass while the boys exercised regularly. Generally, children liked animal protein containing foods and the preference for vegetables was low. In order to improve overall dietary behavior, systematic nutrition education programs reflecting sex difference should be developed. Dish preference data would be very useful in selecting substitutive dish for the s[hoof lunch menu to improve imbalanced diet. (J Community Nutrition3(2) : 69∼76, 2001)

The aim of this study is to survey the eating habits and nutritional knowledge of children in Pusan, with a view to uncovering problems and their underlying causes and cultivating desirable dietary habit and nutrition for children. Three hundred and fifty six elementary school students were asked questions about their eating habits and nutritional knowledge as well as general information about their personal characteristics. The results showed: 1. Only 53.5% of the subjects had breakfast every day. Seventy-six percent of the subjects had dinner every day. Only 40% of the children took meals and talked with family at both breakfast and dinner. Thus there was little opportunity for dietary guidance by parents. 2. About half of the subjects answered that their appetite decreased after eating snack foods between meals. A third of the subjects liked the baked goods as snacks. Because of their high sugar and fat content, they can damage children's health, resulting in child diabetes and tooth decay. For this reason, careful education is necessary to allow children to be able to select snack foods that are appropriate in kind and quantity. 3. About 85% of the subjects had an unbalanced diet. Therefore systematic nutrition education at school is necessary to instill in children the value of balanced diet. 4. Children preferred rice to other cereals as a staple food. They disliked kimchi, seasoned and blanched foods and salads as subsidiary foods. It is therefore necessary to teach children systematically the nutritional advantage of cereals and vegetables and to heighten their awareness of Korean food culture. 5. Children had a low level of nutritional knowledge. The knowledge of specific nutrients was lower than that of foods. In conclusion, systematical educational programs need to be developed at elementary school. These should include information about achieving a balanced diet, good eating habit, meal management and Korean dietary culture. Nutritional education at home must be emphasized.

This study was to investigate the trial status of weight control with internet. A survey was carried out by self-questionnaires with 500 female university students in Seoul. The average height, weight, and PIBW(Percentage of Ideal Body Weight) of subjects were 162.2$\pm$4.8cm, 51.9$\pm$6.1kg and 93.7$\pm$11.0%. It appeared that 50.6% of subjects were abnormal range of body weight : in particular 43.4% of the subjects were underweight. While 80.7% of subjects have deeply interested in weight control, 63.4% of them have attempted diet. It showed that 92.9% of subjects used internet, 54.3 % of them knew internet diet site, however only 39 of subjects used internet diet program. Most subjects used internet diet program in order to acquire diet information. According to PIBW, the overweight group is higher frequency of joining internet diet program than the others group. Therefore, education of weight control was needed with internet in abnormal weight group.

운동과 식이요법을 병행한 체중감량 프로그램에 참여한 여성 비만인의 체지방량, 안정시대사량, 그리고 갑상선 호르몬 차이를 비교할 목적으로 실험한 결과, 체지방량, 체지방율, 체표면적이 유의하게 감소되었고, 안정시대사량 예측치와 실측치 모두 유의하게 감소되었지만, 갑상선 호르몬의 변화는 나타나지 않았다. 안정시대사량과 신체요인들과의 상관분석 결과, 제지방 체충이 가장 밀접한 관계를 보였으며, 안정시대사량과 갑상선 호르몬들과의 관계에서는 TSH와 가장 밀접한 관계를 나타내었다. 결론적으로 8주간 체중감량 프로그램 참여로 체지방은 효과적으로 감소되었으나, 갑상선 호르몬 차이는 없었고 체중감소에 비해 제지방이 유지됨으로써 안정시대사량의 감소는 최소화되어, 에너지 대사작용에 긍정적인 영향을 준 것으로 사료된다.

The purpose of this study was to develop and apply the dietary education program for prescehoolers to improve their vegetable intakes. In this study, 134 mothers of preschoolers were surveyed about the problem of unbalanced food habits in children. A nutrition education program was developed based on the survey results, and then applied in the field to evaluate the effects of nutrition education. Most preschoolers (79.9%) had a relatively low intake of vegetables. The main reason for their unbalanced eating of vegetables was due to texture (34.6%) and taste (30.8%). The activity-based nutrition education program to increase vegetable intake consisted of four lessons. After the nutrition education program was administered for 43 preschoolers, their nutrition knowledge score significantly increased (P<0.001). Preschoolers found the lessons fun (90.9%) and interesting (81.4%), and said they would eat more vegetables in the future (88.4%). This study demonstrates that the unbalanced diet of preschoolers could be modified through the proper introduction of an education program.

By improving body composition, such as fat, lean body mass and total body weight, an exercise program can be an effective treatment of obesity. The effects of exercise on obesity have been confirmed via various approaches such as type, intensity, duration, frequency, and combination with diet. Combined exercise and diet is the most efficient strategy for weight loss, and exercise alone could improve metabolism irrespective of weight loss. In addition, physical activity, including exercise, is emphasized to avoid a 'yo-yo' phenomenon. Exercise increases lipolysis stimulated by such factors as catecholamine, growth hormone (GH), and hormone sensitive lipase (HSL). Moreover, changes in insulin and cortisol through exercise affect adipose tissue, which is known as not only an energy storage locale, but also as an endocrine organ. Adipocytokines secreted by adipose tissue respond to signals that modulate metabolism and inflammation. Exercise has generally shown positive effects on adipocytokines, and these effects increase in conjunction with a hypocaloric diet. However, a long duration and a high intensity of exercise could induce an inflammatory response. This review summarizes the effects of exercise on obesity treatment, which contributes to the exercise and nutritional fields, particularly of community nutritionists.
