The study was designed to investigate the relationship between dietary intakes and the obesity of 400 students who were the third grade in middle school in some areas of Seoul. The survey conducted from March 3 to 13 , 1993. The results obtained were summarized as follows :The average height and weight of surveyed subject were similar to that of standard ( the third grade students in middle school in Seoul, 1991) . Compared to the standard weight/height ratio, subject who belonged to overweight and obese group were 16.4% of male students, 16.1% of female students respectively. Female subjects showed higher ratio than male subjects in skipping meals, frequency of snack per day and concern about a dieting . In case of subjects who belonged to weight /height ratio was high, their speed of dining was fast and they have more concern about a dieting. Compared to the amount of the nutritional intakes of RDA, calcium intakes of male and female subjects were deficient. Especially iron intakes of female subjects were deficient. In takes of Calorie (p<0.01) protein(p<0.05) and fat 9p<0.01) of obese group were higher those of non-obese group. Obese group showed good appetite and overeating also . Correlation analysis showed that obese group seemed to the closely associated with relative body weight of parents, family income, frequency of meals per day, frequency of meals per day, frequency of snack per day, speed of dining and overeating .

This study showed the psychological symptoms, nutritional status and eating behaviors of diabetic patients. General informations on subjects nutritional status were collected by questionnaire, whereas Symptom Check List-90-Revision(SCL-90R) was used for gathering the data related to psychological problem. 34 diabetics in the hospital, aged 49$\pm$10.5 years old, were chosen as the subjects of this study. Their average height was 162.3$\pm$9.4cm and weight was 57.0$\pm$9.5kg. The average period of their suffering from DM was 54.1 weeks. Among, the subjects, 71.0% adapted diet therapy for their disease, whereas 36.7% and 40.7% did diabetic drugs and daily exercise like walking and jogging, respectively, Among 9 psychological symptoms observed, the scores of somatization, depression, anxiety, phobic anxiety and psychoticism were higher than the standard score, however they were not statistically significant. The score of paranoid ideation was lower than standard score. It was statistically significant. As the measure of their clinical status, BMI(body mass index), PIBW(percent ideal body weight) and fasting blood sugar(FBS) were selected 21.6$\pm$2.8, 102.4$\pm$14.8% and 207.8$\pm$19.9mg/이 respectively. The somatization was significantly correlated with subjects duration of DM. Subjects with psychological problems showed wrong eating behaviors. The fasting blood sugar was significantly correlated with the level of depression.

The concentrations of the immunological substances in breast milk and nutritional status were studied in healthy Korean women of middle socioeconomic class. The subjects were recruited at random from obstetric clinics in Seoul. The nutrients intake, prepregnancy BMI, maternal weight gain during pregnancy were studied. The concentrations of lactoferrin(LF), lysozyme(LZ), sIgA, IgG and C3 in colostrum, in transitional milk, and in mature milk, were measured. To elucidate the effect of nutritional status on immunological substances, each components was compared on the basis of either BMI, weight gain, or protein intake. The highest concentrations of the substances were found in colostrum and decreased as lactation progressed. The decline was more prominent in IgG, C3 and sIgA, and less significant in LZ and LF. The colostrum of standard weight gain group showed higher concentrations compared to lower weight gain group. This difference became smaller as the lactation progresses. BMI and nutrient intake status had less significant effect. Lower sIgA was found in lower BMI, in lower weight gain, and lower protein intake groups compared to standard groups, which indicates sIgA is the most affected substance among the measured by nutritional status.

Purpose: Severe acute malnutrition (SAM) is an important public health problem which contributes to significant number of under five deaths. Protocol based management significantly decreases risk of deaths in children with medical complications. Methods: Outcome of children aged 2 months-5 years admitted and fulfilling definition of SAM having diarrhea (group A) was compared to children with SAM having medical complications other than diarrhea (group B). Both groups were managed according to standard recommended protocols and monitored and followed up for 12 weeks after discharge. Results: The average weight gain, defaulter rate, primary failure, secondary relapse rate and readmission rate were similar in both groups. Length of stay in group A was three days longer (p-value=0.039). Discharge rate was comparable with overall 68% of children successfully discharged and 50% of children reaching weight/height > -2 standard deviation at follow-up of 12 weeks. Conclusion: The current management protocol is equally effective for managing children with SAM having diarrhea. Good adherence to management protocol of dehydration and timely modification of therapeutic feeds in children with persistent diarrhea results in satisfactory weight gain.

Purpose: Ménétrier disease (MD) was first described in 1888, and 50 cases have been reported until now. We aimed to discuss the etiology, diagnostics, and management of MD in children. Methods: We searched for case reports published from 2014 till 2019 in English using PubMed. Articles were selected using subject headings and key words of interest to the topic. Interesting references of the included articles were also included. Results: The pathophysiology of MD is still uncertain. However, overexpression of transforming growth factor alpha with transformation of the gastric mucosa has been observed, which may be mediated by genetics and provoked by an infectious trigger. Clinically, MD is diagnosed by abdominal pain, vomiting, anorexia, and edema secondary to hypoalbuminemia. A gastroscopy with biopsy is the gold standard for the diagnosis of MD. In children, the disease is self-limiting and only requires supportive treatment. In general, children have a good prognosis and recover spontaneously within a few weeks. Conclusion: Few pediatric cases of MD have been described in recent years, and with all different etiology. Endoscopy with biopsy remains the golden standard for the diagnosis of MD, and in children, the disease is self-limiting.

본 연구는 어린이 기호식품 품질인증제도를 위한 영양 위생기준안 제안을 통해 어린이 먹거리 안전관리의 체계적 수행을 위한 기반 마련을 목적으로 수행되었다. 어린이 기호식품의 품질인증을 위한 영양 위생기준안 제안을 위해, 초등학교 주변 어린이 기호식품의 실태조사 자료와 위해가능성이 제기된 성분관련 문헌고찰을 통해 영양위해성분을 선정하고, 선정된 성분의 기준치 설정을 위한 EU 및 영국, 미국, 캐나다, WHO, Codex 등 국외의 어린이식품관련 기준치 혹은 유사기준, 관련 법령 등에 대한 선행사례 자료를 수집하여 고찰하였다. 이를 바탕으로 한국인 영양섭취기준과 식품 등의 표시기준, 식품공전, 식품의약품안전청 연구 결과 보고 등을 참조하여 어린이 기호식품 중 가공식품에 대한 영양 위생 기준안을 마련하였다. 제안된 영양 위생 기준 항목 중 영양기준은 열량, 당, 지방, 나트륨이며, 위생기준으로는 식품첨가물(타르색소, 카페인)과 aflatoxin $B_1$, Staphylococcus aureus, Bacillus cereus, Salmonella spp.의 미생물수준으로 하였다. 제안된 어린이 기호식품 품질인증 기준안의 $\ulcorner$저$\lrcorner$, $\ulcorner$중$\lrcorner$, $\ulcorner$고$\lrcorner$ 영양기준치 설정의 현실성을 살펴보고자 시중에서 유통 중인 어린이 기호가공식품 242종을 대상으로 시뮬레이션을 실시해 본 결과, 당, 지방, 나트륨의 $\ulcorner$저$\lrcorner$ 기준치 적용 시에는 조사대상 전체제품 중 0.4%에 해당하는 제품만 포함되었고, $\ulcorner$중$\lrcorner$ 기준치 적용 시에는 최대 22.3%가 해당되었다. $\ulcorner$중$\lrcorner$ 기준치에 1회 분량 당 열량 200 kcal 이하로 제한한 열량기준을 추가 적용한 결과는 17.8%에 해당되는 제품이 기준범위 내에 포함되는 것으로 나타났다. 따라서 품질인증제도의 실효성을 높이기 위해서는 $\ulcorner$중$\lrcorner$ 기준 적용 등의 기준 완화가 필요하며 해당식품 유형이 유가공품과 음료류에 한정되는 결과를 보이므로, 품질인증대상 확대와 제조업체의 참여도를 높이는 측면에서는 각각의 식품유형에 따른 ‘개별 기준치’ 마련이 필요할 것으로 생각된다. 식품유형에 따른 개별 기준치 범위 조정 및 설정을 확립하기 위해서는 추후 체계적인 보완연구가 수행 되어야할 것으로 사료된다.

This study was conducted to abbess dietary intake and eating habits of low-income persons aged 60 years or elder. 212 persons were surveyed between July 10 and August 17, 1978 ; 105 from the farming village of Yang-ju, Kyunggi province; and 107 from Karakdong, an area of redevlopment in the suburbs of Seoul. Results were as follows : 1 ) Family environment 84% of elderly persons surveyed, lived with their children; 13.2%, together as a couple; and 1.9%, widowed, lived alone. More than half on the households had an average monthly income of \50,000 to \30,000. The average Engel index was 61.2%. As for pocket money, 56.4% of male subjects had \l,000 to \7,000 per month, whereas 74% of female had less than \1,000. 2) Anthropometric measurements 59.9% of subjects were $70{\sim}90%$ of standard weight, 93% had an arm circumference only $60{\sim}80%$ of the standard. 3) Food and nutrient intake Carbohydrate provided 73.4 to 79.4% of total energy intake, whereas protein and fat accounted for 10.4 to 10.5% and 8.3 to 7.8%, respectively. Those over 65 years of age showed a somewhat greater dependence on carbohydrates for energy, than those under 65. Protein intake was only $42{\sim}52%$ of the recommended allowance. and the proportion of animal protein to total protein was only $2.1{\sim}9.3%$ far below the recommended allowance. Thus the protein nutrition of the subjects was proven to be inadequate qualitatively as well as quantitatively. Intake of energy and of all nutrients except vitamin A and ascorbic acid, were lower than recommended. 4) Correlational assessment The correlation coefficient between poor dental health, clinical sign score, appetite index, dietary balance and nutrient intake, was significant (0<0.01). Poor teeth, illness, and poor appetite were always associated with inadequate intake of energy and nutrients. The results of this survey reveal that many of elderly of the rural and urban poor show evidence of general malnutrition, The authours hope that this study will provide a back. ground and indicate the direction that community health and welfare programs may take to assure proper nutrition for the elderly.

This study an analyzes the effects of the P/S ratio of dietary lipids and antioxidant vitamin supplements on serum lipids level and fatty acid profile, the degree of lipid peroxidation, and the antioxidant enzyme activities in the liver of rats treated with 7,12-dimethylbenz($\alpha$) anthracene(DMBA). P/S ratio of dietary lipids was made into 0.5, 1 and 2 by mixing palm oil, soybean oil, sesame oil and perilla oil at 10%(w/w) fat level and n-6/n-3 ratio was fixed to 4. Antioxidant vitamin of $\alpha$-tocopherol or $\beta$-carotene was supplemented in addition to vitamin mixture which was given at 1 % of the standard diet. female Sprague-Dawley strain rats, about 60 days old, were divided into three groups(LP : low P/S ratio(0.5), MP : medium P/S ratio (1.0), HP , high P/S ratio(2.0)) and each group was sub-divided into three groups(S ; standard, T ; tocopherol supplemented, C : carotene supplemented): Two weeks after feeding experimental diets, all groups were treated with a single dose of DMBA(2mg/100g BW) by gastric intubation and fed experimental diet for 9 week. The results were as follows ; 1) Serum total cholesterol(TC) level was not significantly influenced by diet but tended to be lower in HP groups compared to LP and MP groups. Triglyceride level was the highest in LP groups and the lowest in $\alpha$-tocopherol supplemented groups. 2) Thiobarbituric acid reactive substance(TBARS) level, representing lipid peroxidation in hepatic microsome, tended to be increased as the unsaturation of dietary lipids increases. $\alpha$-Tocopherol supplement significantly decreased TBARS level. 3) The activities of superoxide dismutase(SOD) and glutathione peroxidase(GSHPx) in hepatic cytosol showed the tendency to be high with increasing P/S ratio of dietary lipids. SOD activity was not significantly influenced by antioxidant vitamin, but GSHPx activity was significantly increased in $\alpha$-tocopherol supplemented groups. In summary, high polyunsaturated fat diet was effective on reducing the serum level of total cholesterol and triglyceride, while it increased unsaturation and peroxidizability of serum fatty acid. With increasing P/S ratio of dietary lipids, lipid peroxidation was increased in the liver and antioxidant enzyme system was induced to inhibit lipid peroxidation against oxidative damage. $\alpha$-Tocopherol supplement was effective in lowering lipid peoxidation, but $\beta$-carotene supplement did not exhibit antioxidant effect.

This study aimed to assess the total sugar intake for Korean and to identify major food sources contributing to those food components. Korean adults aged over 20 years old from the Korean National Health and Nutrition Examination Survey (KNHANES) 2001 and 2002 were selected. The data were analyzed to obtain nationally and seasonally representative information on the health and nutritional status of the Korean. Forty food groups were used in identifying food sources of total sugar and energy intake. Total sugar contents of foods in the KNHANES data sets were estimated by food code matching technique with Release 18 of the USDA National Nutrient Database for Standard Reference. Sample weighted means, standard errors, and population percentages were calculated using SAS and SUDAAN. The mean total sugar intake of the Korean was 60.3g in 2001, 40.9g in spring 2002, 45.7g in summer 2002, and 52.1g in fall 2002, which were 30-44% of intake of US people. Fresh fruit was identified as the most significant food source for total sugar intake in Korean population in all age groups and all seasons. The next major food sources following fresh fruits were candy/jelly/syrup/honey, coffee/coffee caream, vegetables, Kimchi, soft drinks, milk, fruit juice, cookie/cracker/cake, and vegetable juice/grain juice, which showed similar results through the seasons. While carbonated soft drink was the most significant food sources for total sugar or added sugar intakes for US people. The total sugar intakes were significantly higher in women, higher educational level, and residing in metropolitan area. As intake of total sugar increased, intakes of protein, fiber, calcium, phosphorus, iron, Vit A, B1, B2, C, niacin showed significantly increased, while high intakes of added sugars showed low intakes of some micronutrients in the US people. Percentages of people who consumed nutrients below EAR were less in higher total sugar intake group than in lower intake group. From these results, we can conclude that the food consumption habits including the total sugar intake of Korean people seems relatively good so far. More reliable database of total sugar and added sugar composition tables in public domain should be established in the future, and also more researches about total sugar and added sugar for Koreans should be continued.
