장경자(Kyung-Ja Chang) 한국식품영양과학회 1995 한국식품영양과학회지 Vol.24 No.4

체지방이 30% 이상으로 비만이라 판정되는 20~62세의 지원자들에게 저열량 균형식, 무리하지 않은 유산소 운동 및 개인별 비만의 원인을 교정하고 평생체중을 조절하기 위한 영양상담과 교육을 포함한 행동수정을 통해 5주 동안 비만을 치료하고 성인병과 관련된 위험 요인들의 변화를 살펴보았다. 활동량, 식습관, 식이섭취조사를 실시하여 개인별 비만의 원인을 진단한 후 잘못된 식생활을 교정할 수 있도록 주 3회의 영양상담과 매주 1회의 영양교육을 실시하였다. 식이요법은 1일 1끼의 식사와 3회의 조제식이를 통해 열량이 1200㎉ 정도가 되고, 양질의 단백질, 비타민, 무기질은 성인 권장량의 100~150% 이상이 되도록 하였다. 식전에 식이 섬유와 물을 복용하고 식사 기간은 20분 이상으로 천천히 섭취하도록 하였으며, 튀긴음식, 가공식품, 패스트푸드, 술, 청량음료, 달고 기름진 음식, 짜고 자극적인 음식 등은 제한하였다. 주당 3~5일간 1시간 정도의 가벼운 유산소 체조를 실험대상자 전원이 모여서 실시하였다. 먹은 식품, 활동, 운동, 감정상태, 피로여부 등을 일지로서 기록하게 하여 상담을 통해 교정하고 관찰하여 긍정적인 내적동기를 갖도록 교육하였다. 비만치료기간 중 탈락한 대상자의 수는 총 16명 중 5명(31.3%)이였으며, 비만도는 대상자의 대부분이 경증이고, 불규칙적인 식사, 빨리 먹는 습관, 과식, 짜게 먹는 습과, 야식, 음주 등의 비만의 원인이 되는 습관들을 가지고 있어 식습관 점수는 개선이 요구된다고 진단되었다. 5주 동안의 비만치료로 체중은 평균 4.8㎏(주당 0.96㎏)이 감량 되었으며, 체지방, body mass index, 허리, 팔, 둔부의 둘레가 유의적으로 감소되었다. 혈압, 공복시의 혈당, 혈액중의 중성지방, 총콜레스테롤, HDL-콜레스테롤은 변화가 없었으나, LDL-콜레스테롤은 유의적으로 감소하였다. A multidisciplinary weight control program was conducted for obese women. The major components of the program included low calorie diet therapy, exercise, behavior modification and nutritional education and counseling. Sixteen healthy volunteers in excess of body fat, above 30%, were enrolled in the group support program. But 5 person were dropped out in the 2nd week of treatment. During the 1st week of group orientation, individual cause of obesity was assessed through a computer program including survey of dietary intake, activity, eating habits and life styles. During the 5 weeks of treatment, 4.8㎏ of average weight loss was accomplished using a following program ; low calorie diet(1200㎉/day with all essential nutrients), low impact aerobic exercise (50~60% of VO₂max , 1 hour/day in a group, 3~5 days/week), behavior modification of individual life styles and eating habits causing obesity and nutritional education concerning nutrition, role of exercise such as brisk walking, importance of slow eating in regular meal pattern and internal motivation for weight reduction, health risk of obesity and rapid weight loss, weight recycling and yo-yo syndrome, etc. Nutritional counseling was conducted 3 times per week with checking self-records of foods, activity, emotional state and tiredness. Before and immediately after 5 weeks of treatment, blood pressure, fasting blood glucose, cholesterol and triglyceride were measured and compaired with paired t-test. After 5 weeks of treatment, body weight, body mass index, body fat and circumferences of waist, upper arm and hip were significantly decreased. Also LDL-cholesterol was significantly decreased after obesity treatment.

To study the correlation between body composition values and practice of the Standard Guideline for Korean Dietary Life, a nationwide cross-sectional survey was conducted with 378 female college students living in four Korean cities in December 2005. Among the student subjects, 98 were analyzed for body fat mass, percent body fat, waist-hip ratio(WHR), body mass index(BMI) and obesity degree using Inbody 3.0(Biospace Co, Seoul, Korea). Percent body fat was at a high level of 54.1 %, WHR was at a high level of 58.2% and BMI was at a high level of 41.8%. However, both weight and body fat were below normal at 79.5% and 77.6%, respectively. Percent body fat, WHR, and BMI were slightly negatively correlated with vegetable consumption, but slightly positively correlated with beer intake. WHR > 0.8 was significantly negatively correlated with exercise. Standard Guideline for Korean Dietary Life was practiced to and above normal level by 64.6% of the female college students. However, female college students who are within the normal range of body composition value should notice that obesity will relate to abdominal or visceral fat on their body.

This study was performed to investigate stress levels, dietary behaviors and food choices, and their correlations in college students. General characteristic stress scores, using a stress test, and the dietary behaviors and food choices of subjects under stress were measured in 358 subjects (185 males and 173 female). The mean total stress scores of the male and female students were $67.91{\pm}44.85$ and $85.62{\pm}48.91$, respectively. Female students were more stressed than males in relation to family, value, future, friends, and study related factors. There were gender differences in the food intake and frequency of eating sweet things when under stress. Stress increased the food intake and frequency of eating sweet things in female students. Especially, stress factors, such as value, economic, future, friends and study problems increased the food intake of female students. Female students preferred sweet tasting items; whereas, male students preferred hot tasting items when under stress. These results show the effect of life stresses on the dietary behaviors and food choices of college students. Stress not only increased energy consumption in certain individuals, but also changed their food choices. Therefore, education with regard to nutrition is necessary if college students are to practice good eating habits for the correct management of life stresses.

The elderly patients are the most frequent users of digoxin because of increased prevalence of the two primary indications for digoxin therapy; atrial fibrillation (AF) and congestive heart failure (CHF). This study was Performed to observe a variation in digoxin pharmacokinetic parameters in advancing age and changing kidney function, and to compare the measured clearance with the calculated clearance. The 123 drug monitoring records of inpatients who had achieved steady state concentration of digoxin at a tertiary hospital from April 1999 to October 2001 were reviewed. In advancing age, measured digoxin clearance, volume of distribution and creatinine clearance were reduced. Compared with the calculated digoxin clearance, the measured digoxin clearance was more reduced in patients without CHF Especial1y: in elderly patents without CHF the measured digoxin clearance was lower than the calculated digoxin clearance. In contrast to non-CHF patients the measured value was greater than the calculated value in all CHF patients. Findings from this study indicate that the calculated digoxin clearance in elderly patients without CHF substantially overestimated the true clearance. Thus, it appears that the use of calculated digoxin clearance to estimate serum digoxin concentration may result in underestimation of the true serum concentration in a number of elderly patients without CHF.
