본 연구는 젊은 성인을 대상으로 운동 목적에 따른 영양섭취 실태를 조사하고자 수행되었다. 규칙적으로 운동하고 있는 20~30대 남녀를 대상으로 운동 목적에 따라 근육증가군 107명과 체중감소군 107명을 나누어 비교 분석하였다. 그룹별 성별구성을 분석한 결과, 근육증가군은 주로 남성(75.2%)이 많은 반면 체중감소군은 여성(74.3%)이 많이 분포하고 있었다. BMI 판정결과 두 그룹간의 유의적인 차이는 없었으며, 체중감소군의 절반 이상(56%)이 저체중 또는 정상체중으로 나타났다. 근육증가군의 하루 운동시간 및 규칙적으로 운동한 기간이 체중감소군에 비하여 유의적으로 많았다(p<0.01). 영양지식의 상태는 근육증가군의 점수가 체중감소군에 비하여 유의적으로 높은 것으로 나타났다(p<0.05). 식행동 또한 근육량 증가군의 점수가 체중감소군에 비하여 유의적으로 높았다(p<0.05). 영양섭취 상태를 살펴보면, 한국인영양섭취기준과 비교하였을 때 근육증가군의 에너지 섭취비율이 에너지필요추정량의 83.72%로 체중감소군의 74.53%에 비하여 유의적로 높았다(p<0.01). 권장섭취량에 대한 단백질 섭취비율은 근육증가군이 199.62%, 체중감소군은 136.36%로 나타났으며 근육증가군이 체중감소군에 비해 유의적으로 매우 많은 양을 섭취하고 있었다(p<0.001). 권장섭취량에 대한 칼슘 섭취비율은 근육증가군이 67.75%, 체중감소군은 68.64%로 조사되었으며, 두 군 모두 권장섭취량과 비교하여 매우 부족한 수준으로 나타났다. 이와 같이 본 연구에서는 근육증가를 목적으로 운동하는 경우 과량의 단백질을 섭취하고 있었으며, 체중감소를 목적으로 운동하는 경우 필요량에 미치지 못하는 에너지 섭취를 하는 것으로 나타났다. The aim of this study was to investigate the eating behavior and nutritional status of subjects according to their purpose of exercise. A total of 214 subjects, 20 to 30 years of age, who visited fitness centers in Seoul were enrolled. Anthropometrics, exercise habits, nutritional knowledge, and eating behaviors were analyzed using a questionnaire. Nutritional status was assessed by serial 24 h recalls. The subjects were divided into two groups based on their purpose of exercise: increasing muscle (Muscle growth, n=107) or losing body weight (Weight loss, n=107). The Muscle growth group contained a higher percentage of men, whereas the Weight loss group contained a higher percentage of women. The Muscle growth group showed significantly higher scores of nutritional knowledge and eating behaviors compared to the Weight loss group. The Muscle growth group also had a significantly higher intake of energy and protein compared to the Weight loss group. In fact, the intake of energy in the Weight loss group was lower than the estimated energy requirement (EER) for both men and women subjects. The intake of protein in the Muscle growth group was twice as much as the recommended nutrient intake (RNI). The intake of calcium in both groups was less than the RNI. In conclusion, those who exercised with the aim of increasing muscle took excess dietary protein and those who exercised with the aim of weight loss had a lower energy intake than the EER.

본 연구는 스트레스 정도에 따른 영양소 섭취와 대사증후군 위험도를 분석하고자 수행되었다. 본 연구는 40~69세 일반인구 집단을 대상으로 실시한 한국인 역학조사 사업 중 농촌기반코호트를 이용하여 진행하였고, 그중 여성을 대상으로 분석하였다. 대상자들은 사회 심리적 건강측정도구(Psy chosocial Well-being Index, PWI)를 기초로 하여 개발된 18문항의 단축형(PWI-SF)의 평균값을 기준으로 0~26점의 저스트레스군과 27점 이상인 고스트레스군으로 분류되었다. 영양 섭취 상태 및 식습관은 반정량식품섭취빈도조사방법(semi-quantitative food frequency questionnaire, SQFFQ)을 이용하여 평가하였다. 고스트레스군 대상자들은 저스트레스군보다 나이, 허리둘레, 혈압이 유의적으로 낮았으며 신장은 유의적으로 높았다. 혈액분석 결과에서는 고스트레스군이 저스트레스군보다 공복혈당, 인슐린 저항성 지수, 중성지방, 동맥경화 지수가 유의적으로 높았다. 영양소섭취를 분석한 결과 고스트레스군 대상자들이 저스트레스군보다 항산화 영양소인 비타민 A, 비타민 C, 비타민 E, 엽산, 아연, 카로틴을 더 적게 섭취하였다. 과일과 채소의 섭취량 또한 고스트레스군이 저스트레스군보다 유의적으로 적었다. 스트레스와 대사증후군 위험의 관계를 살펴본 결과 고스트레스군 대상자들이 저스트레스군보다 대사증후군의 교차비가 유의적으로 높았다. 결과적으로 한국 농촌 여성에서 스트레스가 높을수록 항산화 영양소와 과일 및 채소의 섭취가 적었으며 대사증후군 위험이 증가하는 것으로 나타났다. The aim of the present study was to investigate antioxidant nutrient intake and risk of metabolic syndrome based on stress level in rural Korean women. Subject were participants from the Multi-Rural Communities Cohort Study, which was a part of the Korean Genome and Epidemiology Study. According to scores of the Psychosocial Well-Being Index Short-Form, a total of 10,111 subjects were classified into ‘low stress group (n=8,015)’ from 0 to 26 points and ‘high stress group (n=2,096)’ above 27 points. Data were collected using self-administered questionnaires, anthropometric measurements, and blood chemical analysis. Dietary nutrient consumption was assessed by a semi-quantitative food frequency questionnaire. High stress group showed lower intake of antioxidant nutrients, such as vitamin A, vitamin C, vitamin E, folate, zinc, and carotene compared to the low stress group. Intake of fruits and vegetable was lower in the high stress group compared to the low stress group. Subjects with high stress showed higher risk of hypertension [odd ratio (OR), 95% confidence interval (CI)=1.226 (1.112∼1.351)] and hypertriglyceridemia [OR, 95% CI=1.227 (1.110∼1.356)] than subjects with low stress. High stress group had a significantly greater odds ratio for metabolic syndrome compared with the low stress group [OR, 95% CI=1.216 (1.101∼1.342]). Thus, the present study suggests that high stress might be associated with low intake of antioxidant nutrients and high risk of metabolic syndrome in rural Korean women.

본 연구는 다이어트가 여대생들의 변비유병율에 미치는 영향 및 관련요인을 조사하고자 수행되었다. 다이어트 유무에 따라 대조군 116명과 다이어트군 135명으로 나누어 비교하였다. 다이어트군의 평균 신장과 체중은 161.96±4.460 cm, 53.87±6.645 kg이었으며 대조군의 경우는 161.42±4.492 cm, 52.77±7.935 kg으로 서로 유의적인 차이가 없었다. 변비유병율을 살펴보았을 때 대조군이 20.7%, 다이어트군이 61.5%로 대조군에 비해 다이어트군에서 변비유병율이 유의적으로 높게 나타났다 (p<0.001). 대조군의 열량섭취량은 1587.53±276.918 kcal인 것에 비하여, 다이어트군의 열량섭취량은 1450.47±328.94 kcal로 유의적으로 낮게 나타났다. (p<0.001). 대조군의 식이섬유 섭취량은 16.18±3.64 g, 다이어트군의 식이섬유 섭취량은 14.0±3.8 g으로 대조군에 비해 다이어트군에서 식이섬유 섭취량은 유의적으로 낮게 섭취하였다(p<0.001). 대조군의 수분 섭취량은 637.9±149.7 g, 다이어트군에서 수분 섭취량은 595.6±173.3 g으로 다이어트군에서 유의적으로 낮게 섭취하는 것으로 나타났다(p<0.05). 대조군에 비하여 다이어트군에서 단백질, 칼슘, 인, 철분, 나트륨 등의 섭취가 적었다(p<0.05). 변비유병율은 식습관점수, 운동생활습관점수, 식이섬유의 섭취, 수분섭취의 세가지 항목에서 유의적인 음의 상관관계를 나타내었다(p<0.05, p<0.001). 이와 같이 본 연구에서는 다이어트를 하는 여대생에서 변비유병율이 높게 나타났으며 변비유병율을 높이는 관련 요인으로 식이섬유와 수분의 섭취가 확인되었다. This study was conducted to investigate the effects of diet on the nutritional status and constipation rate of female college students. A total of 251 female college students living in Gyeonggi province participated in this study. Dietary intake was ascertained from a 3-day dietary record, including 2 weekdays and 1 weekend day. Anthropometrics, general characteristics, diet experiences, dietary habits and prevalence of constipation were analyzed using a questionnaire. The subjects were divided into two groups, a control group (n=165, 46.2%) and a diet group (n=135, 53.8%). There was no significant difference in age, height, weight or BMI between groups. The prevalence of constipation was higher in the diet group than the control group. The intakes of energy, dietary fiber and water of the diet group were significantly lower than those of the control group. Correlation analysis revealed that the prevalence of constipation was negatively associated with exercise score, dietary fiber intake and water intake. It is postulated that dietary habits might be important factors contributing to constipation. Accordingly, nutrition education aimed to improve intakes of fiber and water may be necessary during weight control periods.

Purpose: Enteral feeding remains controversial in patients receiving extracorporeal membrane oxygenation (ECMO), particularly in those treated with a high-dose vasopressor. This study examined the safety and feasibility of enteral nutritional support for patients undergoing ECMO in a cardiac care unit (CCU). Methods: Adult patients admitted to the CCU undergoing ECMO from January 2014 to May 2015 were included. Patients with <48 hours of support, undergoing ECMO at another hospital, and inaccurate medical records were excluded. Results: Among the 14 patients undergoing ECMO in the CCU, 2 patients were diagnosed with malnutrition and the others were in the normal state in the initial assessment. On the other hand, they had the malnutrition risk factors (anorexia, weight loss, fluid retention, and hypermetabolic state). Thirteen patients received enteral nutrition and 1 patient had possible oral intake. The average initiation day of enteral nutrition was 2.0±1.6 days on ECMO. The mean duration of enteral nutrition was 5.2±4.9 days and the target goal was achieved within 3 days. There were no serious adverse effects for enteral nutrition but 3 patients had gastrointestinal problems (diarrhea and anorexia), and gastrointestinal bleeding occurred in 1 patient. In 1 case, enteral nutrition had to be stopped due to the prone position. Overall, 5 patients were cured, 3 patients recovered through heart transplantation, and 6 patients died. Conclusion: Most CCU patients receiving ECMO were well nourished but had the malnutrition risk factors in progress. These results suggest that enteral feeding might be safe and feasible in patients treated with ECMO but there were minor side effects.

This study was performed to investigate the effects of garlic on uncoupling protein 2 (UCP2) transcriptional regulation of UCP2- luciferase transgenic mice fed on a high fat diet to induce obesity. To examine the transcriptional regulation of UCP2, we generated transgenic mice with a UCP2 promoter (-1,830/+30 bp) containing luciferase as a reporter gene. UCP2-luciferase transgenic mice were fed a 45% high-fat diet for 8 weeks to induce obesity. Subsequently, mice were maintained on either a high-fat control diet (TG-CON), or high-fat diets supplemented with 2% (TG-GL2) or 5% (TG-GL5) garlic for a further 8 weeks. Dietary garlic reduced body weight and energy efficiency ratio in the TG-GL5 group, compared to the TG-CON group. Furthermore, garlic supplementation significantly decreased white adipose tissue fat mass and plasma levels of triglycerides, total cholesterol, and leptin in the TG-GL2 and TG-GL5 groups, compared to the TG-CON group. Specifically, UCP2 promoter activity in metabolic tissues such as liver, white adipose tissue, brown adipose tissue, and skeletal muscle was increased by garlic supplementation. These results suggest that dietary garlic was partially associated with an increase of UCP2 transcriptional activity in metabolic tissues for decreasing obesity.
