  • This study was conducted to investigate the relationship among pereption of obesity, experience of weight control control and satisfaction with body image in adolescence. The subjects were 221 high school students(91 boys, 130 grils), aged 16.7 years living in a rural area. To determine the perception of obesity, knowledge about obesity, belidfs about obese people, and attitudes towards obese people were measured. The results were as follows: There was high correlation between beliefs about obese people and attitudes toward obese people. When the perception of obesity was compared by sex, girls had significantly more accurate knowledge, stronger beliefs that obesity couldn't be controlled by oneself, the higher the eating disturbance score was. It also appeared that BMI was positively correlated with the positive attitude towards obese people.

  • The purpose of this study was to investigate the eating behavior, food preference and nutrition knowledge according to the body style of male college students. The subjects were 219 male students enrolled in University, Taegu. The data was collected by using a survey questionnaire and an anthropometric measurement. The results were summarized as follows: The mean height, weight and BMI of subjects were $173.8{\pm}8.7cm,\;65.8{\pm}7.9Kg,\;and\;21.9{\pm}2.4$, respectively. The subjects were divided into three groups according to the BMI: underweight group(<20); normal group(20-25); and overweight group(>25). One third of the subjects preferred to gain weight(33.8%); 47 subjects preferred to lose weight(21.5%); and the rest of the subjects satisfied their physique(44.7%). Most of subjects considered 'supper' as the most important meal during a day. Among the food items, the most frequently and evenly ingested item by subjects was 'Kimchi' : 'Ham and sausage' was the least preferred food among subjects. There was no significant difference in preference among three groups and almost half of the subjects had irregular meal time because of busy schedule. The preference for meat showed high score among underweight group; on the other hand, the preference for fruits and vegetables showed high score among overweight group. Usually subjects gained nutrition knowledge through media including newspaper, magazine and TV. There was no significant difference of the nutrition knowledge score among three groups. Based on these results, nutrition education program for the college student should be arranged in the classes.

  • 어류의 번식활동은 뇌-뇌하수체-생식소로 이어지는 내분비기관이 주로 담당하고 있으며, 그 중에서 뇌하수체에서 만들어지는 생식선자극호르몬 (GTH)은 생식소 발달에 매우 중요한 역할을 한다. 한편, GTH는 생식소에서 생성되는 스테로이드호르몬에 의해 유전자의 발현이 조절된다. 본 연구에서는 산천어 (Oncorhynchus masou)의 GTH 유전자발현에 미치는 estradiol-17$\beta$ (E2)의 영향을 생체내에서 먼저 조사하고, 유전자발현조절의 메카니즘을 구명하기 위하여 에스트로젠 수용체 (ER)의 cDNA를 cloning하였다. 또한 내분비교란물질로 알려져 있으며 에스트로젠 수용체와의 유사결합작용이 알려진 노닐페놀 (NP)의 영향도 아울러 조사하였다. 미성숙 산천어를 E2 및 NP (각각 5 mg/kg 및 10 mg/kg 체중)로 처리하면 72 시간째에 뇌하수체내의 $\beta$-actin mRNA에 비해 GTH (FSH$\beta$, LH$\beta$) mRNA가 상대적으로 증가하는 경향을 나타내었다. 뇌하수체에서 분리한 ER의 기본적인 구조는 DNA결합도메인 (Zf-C4), 호르몬결합도메인 (hormone_rec), 기타 전사활성화도메인으로 구성되어 있었으며 (그림 1), 기존에 보고된 에스트로젠 수용체중에서 무지개송어 및 대서양연어의 ER과 각각 98%, 96%의 높은 상동성이 관찰되었다. 향후, 준비된 ER을 재료로 하여 GTH 유전자발현의 호르몬의존성을 조사할 예정이다.

  • This study was to designed to investigate the effects of nutrition education and exercise program for overweight or obese female adults, and also emphasize the necessity of a proper nutrition education. The anthropometric characteristics, nutritional intake, eating habit, and hematological index, physical examination were measured before and after program. Considering the time schedule of the subjects, the exercise program was divided into 3 sessions (morning, afternoon, and evening) and the subjects performed swimming and weight training for 4 weeks. The subjects were overweight or obese women, with an average age and height of each 46.1 and 156.3 cm. The weight and BMI were decreased significantly after nutrition education and exercise program. The back region of front arm (p<0.001), infrascapular region (p<0.001), body fat (p<0.001) were significantly decreased, and grasping power (p<0.01), back muscle power (p<0.001) were significantly increased after nutritional and exercise program. Total triglyceride level and fasting blood glucose (p<0.001) were decreased significantly after program. The intakes of vitamin D and vitamin $B_1$ were significantly changed after nutrition and exercise program. As for eating behavior and nutritional knowledge evaluation after program, the average score increased significantly (p<0.001). The results of this study show that this nutrition and exercise program can be an effective approach to improve their hematological index and nutritional and health status.

  • 현대사회에서 청소년기에 발생하는 영양문제 중 가장 빈번히 나타나는 청소년기 비만은 성인 비만으로 이행되기 쉬우며, 당뇨병, 지방간, 고혈압과 같은 각종 성인병의 발생과도 관련이 있다. 또한 체형에 대한 관심이 증가하고 있는 현대사회에서 편견의 대상이 됨으로 인한 심리적 장애를 발생시키기도 한다. 이에 따라 비만인의 체중조절을 위한 다양한 교육프로그램들이 실시되고 있는데, 현재까지의 실시되고 있는 프로그램들은 강의식교육이 주류를 이루고 있어 적극적인 교육효과를 이끌어 내는데 많은 한계점을 가지고 있었다. 이에 본 연구자들은 지역보건소를 중심으로 2박 3일간의 청소년 캠프 프로그램을 통하여 VTR감상, CAN-Pro를 이용한 섭취 식단의 평가 및 영양상담, 영양뷔페, 역할극, 다양한 영양지식 응용게임, 일상생활에서 활용가능 한 운동교육, 비만의 원인과 건강과의 관련성 및 식사요법 등에 대한 강의를 실시하였다. 캠프 참가자들은 부천시에 거주하는 중학생으로 사전에 신장과 체중에 대한 조사를 바탕으로 비만으로 판정된 총 42명(남 28명, 여 14명)으로 하였다. 캠프 시작전과 후에 설문조사를 통하여 영양지식, 영양태도, 자아만족도에 관한 조사를 실시하여 프로그램 직후의 효과를 판정하였고, 일상적인 영양소섭취상태를 평가하기 위해 24시간 회상법을 통하여 캠프참가 전날의 식이섭취 조사를 실시하였다. 대상자의 평균 연령은 13.9세로 남녀학생 간에 유의적인 차이가 없었으며, 신장은 남학생이 160.7cm, 여학생이 156.8cm였다. 체중, 체질량지수, 비만지수, 허리엉덩이둘레비 및 체지방 함량은 남학생이 각각 75.5kg, 29.1kg/$m^2$, 30.1, 0.89, 33.3%이었고, 여학생이 각각 67.8kg, 27.5kg/$m^2$, 25.3, 0.81, 34.6%였다. 영양소 섭취량에 대한 분석결과 열량의 경우 남학생이 2137.7㎉, 여학생이 2059.7㎉ 섭취수준을 보였으며, 총열량에 대한 당질, 단백질, 지질의 섭취 비율은 남학생 57:14:29, 여학생 60:13:26으로 남여학생 모두 총열량에 대한 지질의 섭취 비율이 높았다. 프로그램의 효과 평가를 위하여 남녀중학생을 모두 합하여 비교하였을 때 프로그램 실시 후 영양태도가 유의적으로 향상되었으며(p<0.001), 자아만족도 및 영양지식에 있어서는 유의적인 변화가 나타나지 않았다. 그러나, 성별로 분류하여 비교 시 남학생은 영양태도(p<0.01)와 영양지식(p<0.05)이 유의적으로 향상되었고, 여학생의 경우에는 영양태도(p <0.01)에서만 유의적인 향상을 나타내었다. 이상의 결과에서 2박 3일간의 청소년 캠프는 남녀 비만중학생에 있어 영양태도의 향상을 가지고 왔으며, 남학생의 경우에는 영양지식에도 유의적인 향상이 나타났다. 그러나 영양교육의 효과가 실제적인 영양소섭취 및 비만도의 변화에 영향을 미치는지를 알아보기 위해서는 지속적인 추적 관리를 통한 효과판정이 필요한 것으로 보여진다.

  • This study investigated the effects of an antifat diet with $\beta$-cyclodextrin on the reduction of body weight, obesity index, body mass index, body fat mass, body circumferences and plasma lipid levels in obese Korean women. After maintaining an antifat diet for 45 days, there were significant reductions in body weight by 4 kg, obesity index by 5%, body mass index by 1 kg/$m^2$ and body fat mass by 7% as absolute values (p<0.05). When expressed as percentages of the decrease, these reductions remained significant at 4%, 13%, 4% and 20%, respectively (p<0.05). In addition, after maintaining this antifat diet for 45 days, there were also significant reductions in arm, waist, hip and thigh circumferences by 3 cm as absolute values when compared to before intake of antifat diet, and these reductions remained significant at 8%, 3.4%, 3% and 5%, respectively (p<0.05) as percentages of the decrease. Furthermore, this antifat diet significantly reduced triacylglyceride by 103 mg/dL, total cholesterol by 50 mg/dL and LDL-C by 50 mg/dL respectively (p<0.05). Thus, the present results demonstrate that $\beta$-cyclodextrin may have benefit as a novel food resource for diets to prevent obesity and control overweight in adult women.

  • 당뇨병으로 인한 태아의 위험은 당뇨병의 유전요인보다는 임신부의 대사 장애에 의한 것으로 당뇨병 형태에 따른 태아의 위험 차이는 없는 것으로 추축할 수 있다. 그러나 제 1형 당뇨병임신부는 케톤산혈증이 발생할 가능성이 높고 케톤산 혈증이 발생하면 태아 사망의 가능성도 높아진다. 또 제 1형 당뇨병임신부는 당뇨병성 혈관합병증이 동반될 가능성이 많아 자기의 주 수 보다 체중이 미달되는 경우와 조산 및 임신 중 고혈압질환이 발생할 위험성이 높아진다. 제 2형 당뇨병임산부는 임신부가 비만일 경우 거대아 출산 및 임신 중 고혈압질환이 발생할 위험이 높아진다. 그러나 대부분의 합병증은 임신 전과 임신기간 동안 양호한 혈당조절로 감소시킬 수 있다.

  • This study was carried out to investigate perception about body image, dietary attitude, nutrient intake and dietary self-efficacy of high school students in Pusan. A questionaire survey was distributed among 491 high school students. The survey was conducted from April 8 to April 22 in 2002. The results are summarized as follows. Forty percents of the underweight group, 53.9% of the normal weight group, 61.8% of the overweight group and 48.2% of obesity group have correct perception about their body image. Most of the students were concerned with their body image and weight control. Obesity of parents was significantly correlated with obesity of the subjects (p<0.01). The higher obesity rate, the lower dietary self-efficacy. The higher dietary self-efficacy, the higher dietary attitude. There was a significant positive correlation between the education level of their parents and dietary attitude of the subjects (p<0.01) and a significant negative correlation between obesity rate of their mothers and dietary attitude of the subjects (p<0.01). Dietary attitude scores showed no significant difference among the groups. Intakes of most nutrients, except protein, niacin and vitamin C, were lower than those of the recommended dietary allowances for Koreans. Therefore, proper nutrition education is required to improve their nutritional status and dietary self-efficacy.

  • This study aimed to identify binge-eating behavior and food addiction in Korean population and to determine their associations with obesity, eating behaviors, mental health and cognitive characteristics. We collected clinical questionnaire scores related to eating problems (e.g. binge eating, food addiction, food cravings), mental health (e.g. depression), and cognitive functions (e.g. impulsivity, emotion regulation) in 257 Korean adults in the normal and the obese weight ranges. Binge-eating and food addiction were most frequent in obese women (binge-eating: 46.6%, food addiction: 29.3%) when we divided the participants into 4 groups depending on gender and obesity status. The independence test using the data with propensity score matching confirmed that binge-eating and food addiction were more prevalent in obese individuals. Finally, we constructed the logistic regression models using forward selection method to evaluate the influence of various clinical questionnaire scores on binge-eating and food addiction respectively. Binge-eating was significantly associated with the clinical scales of eating disorders, food craving, state anxiety, and emotion regulation (cognitive reappraisal) as well as food addiction. Food addiction demonstrated the significant effect of food craving, binge-eating, the interaction of obesity and age, and years of education. In conclusion, we found that binge-eating and food addiction are much more frequent in females and obese individuals. Both binge-eating and food addiction commonly involved eating problems (e.g. food craving), but there was difference in mental health and cognitive risk factors. Therefore, it is required to distinguish food addiction from binge-eating and investigate intrinsic and environmental risk factors for each pathology.

  • Thermogenesis in brown adipose tissue (BAT) can serve the animal in the regulation of its body temperature and of its body weight. Thermogenesis can be switched on by exposure of the animal to cold (non-shivering thermogenesis) or by overeating (diet-induced thermogenesis). BAT mitochondria are uniquely specialized for thermogenesis, possessing a specific proton conductance pathway that is regulated by the concentration of fatty acids in the cells of BAT. The level of fatty acids is in turn controlled by the lipolytic action of noradrenaline on the tissue. When the proton conductance pathway operates, the mitochondria are effectively uncoupled and exhibit extremely high rates of substrate oxidation with a great increase in heat production. Thus it is suggested that BAT is of importance in energy balance and human obesity treatment if thermogenesis can be stimulated specifically.
