This study investigated the factors affecting restrained and emotional eating according to the BMI of college women in Seoul. Based on their weight, 514 college women were divided into 3 groups. General demographics, nutrient consumption, eating habits and DEBQ were subsequently evaluated. Multiple regression analysis was performed to determine the factors responsible for restrained and emotional eating in each group. Percentage of the overweight or obese group having negative emotions, such as frequency of overeating (p<0.05), habitual eating, regret, and guilt after overeating, was higher as compared to the other groups (p<0.001). Considering factors that affect restrained eating, negative emotion after overeating had a positive correlation in the underweight group (β=0.481, p<0.001). In the normalweight group, the BMI (β=0.201, p<0.001), total food intake (β=0.241, p=0.002), and negative emotion after overeating (β=0.284, p<0.001) positively affected restrained eating. In the underweight group, habitual eating (β=0.292, p=0.002) and negative emotions after overeating (β=0.233, p=0.012) were determined to affect emotional eating. Moreover, habitual eating (β=0.290, p<0.001) and negative emotions after overeating (β=0.172, p=0.004) were observed to influence emotional eating in the normal weight group. In the overweight and obese groups, habitual eating was determined to affect emotional eating (β=0.410, p<0.001). Taken together, these results provide a basis for creating a weight control program for young women having undesirable eating behaviors, such as restrained and emotional eating.

본 연구는 여대생의 체질량지수와 다이어트 인식 및 다이어트 행동에 관해 알아보기 위해 시행된 서술적 조사연구이다. 연구 대상자는 일 지역 여자대학교에 재학 중인 학생 165명으로 자료수집은 2018년 10월 29일부터 11월 9일까지 진행되었다. 수집된 자료의 분석은 SPSS/WIN 21.0 프로그램을 이용하여 기술통계, t 검정, 일원분산분석, 교차분석을 하였다. 전체 다이어트 인식은 3.44점이었고 요인별로는 ‘실행’이 4.00점으로 가장 높게 나타났고, 그 다음으로 ‘정보 및 교육’이 3.58점, ‘필요성’은 3.32점, ‘자가인식’은 2.84점으로 가장 낮게 나타났다. 다이어트 횟수는 ‘3회 미만’이 65명(43.0%)으로 가장 많았으며 방법은 ‘음식조절’이 65명(43.0%), ‘운동’이 62명(41.1%) 순이었다. 일주일간 운동시간은 3시간 미만이 99명(65.6%)으로 가장 많았고 ‘전혀 하지 않는다’가 32명(21.2%)으로 그 다음 순이었다. 다이어트로 인한 피해경험은 22명(14.6%)이 있다고 응답했고, 종류로는 위장병, 생리불순, 탈모 등이었다. BMI에 따른 다이어트 인식 전체 점수는 저체중군이 정상체중 및 과체중군보다 점수가 낮게 나타났다(p<.001). 하부 요인별로 보면 다이어트 ‘실행’은 저체중군이 정상체중 및 과체중군보다 점수가 낮게 나타났고(p<.05), 다이어트 ‘정보 및 교육’은 과체중군의 점수가 가장 높았고, 그 다음이 정상체중군, 저체중군 순이었다(p<.001). 다이어트 ‘필요성’과 ‘자가인식’은 저체중군이 정상체중 및 과체중군보다 점수가 낮게 나타났다(p<.001). 다이어트 인식에 따른 다이어트 행동은 다이어트 횟수와 방법에서 차이가 있었다(p<.001). 본 연구 결과를 토대로 여대생의 올바른 다이어트 인식 형성과 건강한 생활유지를 위한 관심과 교육이 필요하다고 사료된다.

본 연구는 체육전공 남녀 신입생들을 대상으로 체질량지수(Body mass index; BMI), 신체이미지, 식사태도 및 신체활동량의 차이와 상관관계를 규명하는데 있다. 남녀 체육전공 신입생 595명(남녀: 341 vs. 254)이 본 연구에 참여하였고, 대상자들은 신체이미지(Body sahpe questionnaire; BSQ), 식사태도(Eating attitude test-26; EAT-26), 및 신체활동(International physical activity questionnaires; IPAQ)에 대한 설문지를 작성하였다. 체질량지수에 따라 분류하였을 때 정상체중은 67.2%로 나타났으며, 저체중은 5.4%, 과체중과 비만이 17.8%, 9.6%로 나타났다. 남학생들의 57.7%와 여학생들의 78.7%는 정상체중으로 분류되었다. BSQ 검사 결과 총 대상자 중 불만족의 비율은 48.2%로 나타났으며, 남학생 22.9%와 여학생 82.3%가 불만족으로 나타났다. EAT-26 검사 결과 전체 20.2%가 비정상적인 식사태도를 가지고 있었으며, 남학생과 여학생의 비율은 7.3% vs. 37.4%로 나타났다. 신체활동량 조사 결과 99%의 대상자들이 활동적으로 조사되었다. BMI, BSQ, EAT-26, 그리고 신체활동량은 남녀 간에 통계적으로 유의한 차이를 보였다. 신체이미지와 식사태도는 남녀 대상자 모두에서 유의한 상관관계를 보였으며, 체질량지수는 남자 대상자들에서만 신체이미지와 식사태도와 유의한 상관관계가 있었다. 그러나 신체활동량은 남녀 모두에서 다른 변인들과 상관관계가 없었다. 결론적으로 체육전공 대학생들의 신체불만족과 비정상적인 식사태도의 비율이 높으며, 신체이미지의 불만족이 높을수록 비정상적인 식사태도를 가지고 있는 것으로 조사되었다. 따라서 이에 적합한 교육과 사회적 인식의 전환이 필요할 것으로 사료된다.

The purpose of this study was to investigate the eating patterns, nutrient intakes, blood levels, and health status of male college students in Seoul according to body mass index (BMI). In this study, we classified subjects into normal weight (n=240), under weight (n=11), and obese (n=46) groups according to BMI. The weight and BMI were significantly higher in the obese group compared to other groups (p<0.0001). The obesity was associated with overeating and frequent eating. The under weight group showed significantly higher consumption of fast food, snacks, and fried foods compared to the other groups (p<0.05). The intakes of milk, meat, fish, eggs, and fried food and preference ratios were higher in the obese group (p<0.05). The male college students in this study showed insufficient intakes of calories, vitamin C, folic acid, and calcium. The plasma LDL-cholesterol levels in the obese group were higher compared to the other groups. In conclusion, intake of nutrients among male college students is found to be insufficient and requires nutritional education. The under weight group showed regular eating habits and increased nutrient intake. The obese group was shown to need more exercise with higher intakes of vegetables and fruits.

The purpose of this study was to compare the validity of obesity indices among the body mass index (BMI), waist circumference (WC), and body fat percentage (BF%), and to determine which is the most useful index to predict the risk of chronic diseases of elderly people. This study was conducted as a cross-sectional study at welfare centers in Seoul. The total number of subjects was 261 (68 men and 193 women) with age ≥60 years. The distribution of obesity using 3 obesity indices in the subjects with hypertension, diabetes, or arthritis was BF%>WC>BMI in elderly men and WC>BF%>BMI in elderly women. In elderly women, odds ratios (ORs) for hypertension in BMI and WC quartiles were significantly increased in quartile 2 and 3 (p<0.05). The ORs for hypertension, hyperlipidemia, and arthritis in BF% quartiles were significantly increased in quartile 3 and 4 (p<0.05). The BF% was sensitive obesity index for predicting the occurrence of chronic disease in men, and the WC was sensitive index in women. Our results suggested maintaining BMI less than 23.5 kg/m2, WC less than 82 cm, and BF less than 35% in order to prevent chronic diseases in elderly women.

The purpose of this study is to examine the relationships between body mass index (BMI), satisfaction of perceived somatotype, and eating disorder of 133 female college students from Gyeong-gi province. The average weight is 55.3±8.8kg, and the BMI is categorized into three groups: underweight, normal weight, and overweight. In terms of the satisfaction for perceived somatotype, 58.6% of the total respondents replied "unsatisfied," which consists of 14% of the underweight group, 37.6% of the normal weight group, and 6.8% of the overweight group. This reveals that the negative association between the satisfaction levels of perceived somatotype and BMI in the normal weight group is statistically significant (p<0.001). Among three eating disorder scores, the first factor, the drive for thinness, shows significant difference (p<0.005) among groups with 2.82 points in the underweight group, 3.38 points in the normal weight group, and 3.86 points in the overweight group; such result shows that there is a drive for being skinny even within the underweight group. Second, the satisfaction levels of perceived somatotype type shows significant dissatisfaction among all groups with 3.41 points in the underweight group, 4.15 points in the normal weight group and 4.73 points in the overweight group. Third, the bulimia degree reveals a significant difference within each group, 2.15 points in the underweight group, 2.33 points in the normal weight group, and 2.78 points in the overweight group. Overall, more than half of the female college students are dissatisfied with their body shapes despite the fact that they are under or within the normal weight. In addition, the drive for being skinny and dissatisfaction levels of perceived somatotypes appear to be significantly higher with higher BMI levels.

The purpose of this research was to study food behaviors and nutrient intakes according to body mass index(BMI) and body image recognition in 211 female university students in Incheon. The majority of the surveyed subjects were in the normal range for BMI. Most of these female university students preferred a thin body type and were not satisfied with their body shapes. Most also controlled their body weight for appearance by exercising and limiting food intake. The obese group often ate processed foods(p<0.01) and ate out(p<0.05). The underweight group and normal-weight group took vitamins and supplements more frequently(p<0.001). Those students who recognized their body image as a ``fat shape`` had good appetites(p<0.05) and those who recognized themselves as ``normal shape`` considered food formulations ate every meal (p<0.05) and consumed vitamins and other supplements frequently(p<0.01). The mean calorie intake of all students was about 80% of the recommend amount, so there was a risk of lack of various nutrients. The ``fat`` students by body image recognition had lower calorie intakes in order to reduce body weight. In all the groups, there was a lack of vitamins B1 and B2, as well as the minerals Ca and Fe. Therefore, education on correct body image recognition and training on proper weight control are deemed necessary. In addition, education and counseling on nutrition that are tailored to individual status are needed.

The purpose of this study was to assess dietary variety by body mass index, waist circumference and exercise habits in 138 female university students residing in Bucheon and its adjacent area. Body mass index(BMI), waist circumference (WC) and exercise habits were assessed via a self reporting questionnaire, and a 3-day dietary recall survey was conducted by interviewing. Dietary variety was assessed by dietary diversity score(DDS), meal balance score(MBS), and dietary variety score(DVS). The average BMI, WC, DDS, MBS, and DVS were 20.7±2.59㎏/㎡, 69.3±5.03㎝, 3.87±0.57, 7.27±1.48, and 12.59±3.14, respectively. The DDS for breakfast, lunch, supper and snack were 1.80±0.92, 2.45±0.48, 2.49±0.55 and 0.53±0.52, respectively. DDS, MBS, and DVS were not significantly correlated with BMI, WC and exercise habits. However, DDS for breakfast and supper were significantly higher(p<0.05) and lower(p<0.05) respectivly in subjects who exercised regularly compared to those who did not exercise regularly. And DDS for snack was significantly higher in subjects whose awareness of health status was good or somewhat compared to those whose that was bad(p<0.05). These findings suggest that nutritional education based on female university students` eating variety and regular exercise may be required to improved dietary variety.

The purpose of this study was to provide basic informations for educating juveniles on desirable body image recognition by examining their body image recognition and comparing and finding problems according togender and body mass index (BMI) in middle school students. The average age of the subjects was 15, their average height was 162.5㎝, their average weight was 53.5㎏, and their average BMI was 20.1㎏/㎡. Male students wanted togain weight and female students wanted to lose weight. As for body shape, female students thought that they were fat more often than male students. Also the more overweight the students were, the higher their concerns and experiences toward weight control. Among weight control methods, exercise scored highest in all BMI groups. Over 80% of the respondents answered that their weight control effort were not systematic such as via professional counseling. As for the frequency of eating breakfast and dinner in female students, the more a student was overweight, the lower their frequency of eating breakfast and dinner. Many respondents answered that a typical meal time was ``10∼20 minutes``. The average eating habit score for all subjects was 38.0. The eating habit scores of male students were significantly higher than those of female students, and there were no significant differences among BMI groups. Eating habit score of ``I have more than two meals with rice everyday`` in female overweight group was significantly higher than those of other two groups. These results indicate that the female students` degree of preference for a slim body shape were higher than those of male students. In addition, weight control by students is not systematic through professional counseling; instead they attempt to control their weight by themselves such as a meal skip, which lead to potential danger that they may lose weight carelessly. Therefore, correct body image recognition is greatly needed, and families and schools should make ceaseless efforts to help students properly control their weight and have correct eating attitudes.

The purpose of this study was to investigate the factors influencing body mass index of 618 university students located in the Gwangju area, from Nov. 20th to 30th, 2002. The subjects included 301 males(48.7%) and 317 females(51.3%). This survey was conducted using a self-administered questionnaire. The percentage of students who were underweight, normal and overweight based on their body mass index(BMI) was 3.7, 88.0 and 8.3 for the males, and 29, 71 and 0 for the females, respectively. Most students (73.8%) skipped breakfast. This was because of lack of time(65.1%) of the cases. Self-reported eating habit problems were eating irregular meal(52.4%), overeating(21%), prejudiced meal(12.4%) and skipping meal(7.4%). The type of favorite snack was biscuit(31.9%) and cup Ramyon(31.9%). The type of favorite beverage was juice(23.3%). The coffee intake was higher in males compared to females. The rates of alcohol drinking in male and female students were 88.0% and 85.8% respectively, and the rates of smoking were 35.9% and 2.8% respectively. Percentages of weight control experience were 30.2 and 51.4 in the male and female, respectively. The BMI of students living in home and eating breakfast was higher than that of the other students. The BMI of students eating cup Ramyon and water increased. The BMI of students taking regular exercise and weight control tended to be higher than that of subjects not doing so. When the amount of pocket money available and the rates of coffee intake, alchol drinking and smoking increased, the BMI was increased. Therefore, nutritional education for university students is needed so as to improve their health and to modify life habits and nutritional education program should be developed to meet the various needs of these students.

This study was designed to investigate food consumption patterns and nutrient intakes of college students, divided into subgroups of normal weight men (no.=140), normal weight women (no.=101), and underweight women (no.=155) by body mass index. Frequency of food eaten, nutrient intakes from each meal, percentages of RDAs, and nutrient densities were analyzed using 24-hour recall records. It was very interesting in these results as follows. Normal weight men ate on the whole more frequently than other groups. Underweight women had higher intakes of nutrient than did normal weight women. However normal weight women consumed food of greater nutrient density than did other college students. Consequently, it is desirable to suggest nutrient density of food than learn RDAs for adequate diet in nutritional education programs.

본 연구는 자동노출제어 (AEC; Automatic Exposure Control)를 이용한 복부 일반 X선 검사에서 체질량지수 (BMI; Body Mass Index)가 입사표면공기커마 (ESAK; Entrance Surface Air Kerma)에 미치는 영향에 대해 알아보았다. 연구방법은 AEC를 이용하여 복부 일반 X선 검사를 시행 받은 321명을 대상으로 키, 몸무게, BMI와 ESAK의 관계 및 BMI범주 (Underweight, Normal, Overweight, Obese 1, Obese 2)에 따른 평균 ESAK값을 비교하였다. 연구의 결과 몸무게 (R2=0.777, p<.001)와 BMI (R2=0.835, p<.001)는 ESAK와 양의 상관관계가 있었던 반면, 키 (R2=0.075, p<.001)와 BMI는 뚜렷한 상관관계를 확인할 수 없었다. BMI범주에 대한 평균 ESAK는 통계적으로 유의한 차이를 보였으며, 사후분석을 통해 유의수준 0.05에 대해 5개의 부집단이 존재하여 모든 BMI범주 간 ESAK값의 차이가 있는 것을 알 수 있었다. 또한, 인접한 BMI간 ESAK값 증가폭이 Underweight에서 Obese 2로 갈수록 점차 늘어나 BMI가 증가할수록 피폭선량이 급격하게 증가되는 것을 알 수 있었다. 따라서 복부 일반 X선 검사에서 AEC를 사용할 경우 BMI가 증가함에 따라 과도한 선량이 조사될 수 있음을 인식하고 검사조건을 고정하여 촬영하는 등의 노력을 통한 선량저감화가 필요할 것으로 판단된다.

비흡연자와 한국형 알코올 선별 검사법 (AUDIT-K)설문지 척도점수에 따라 적정음주군(10점 이하)을 연구대상으로 하여 뇌 백질의 손상 유무를 파악 할 수 있는 확산텐서영상을 검사하고 영상을 획득 한 후 Tract-Based Spatial Statics(TBSS)방법으로 뇌 백질 부위의 신경섬유로의 비등방도 FA(fractional anisotropy)값을 측정 분석한 결과 연령과 체질량지수(BMI)의 변인에 따른 뇌 백질 모든 영역에서 FA값은 통계적으로 유의하지 않았으며 본 연구의 결과 값으로 추측하자면 즉, 연령과 체질량지수(BMI)는 뇌 백질의 미세구조성 변화에 크게 영향을 미치지는 않는다고 할 수 있다.

본 연구에서는 체질량 지수에 따라 각기 다른 관전압을 적용하여 비뇨기계 CT 검사 시 체질량 지수 적용의 유용성을 평가하고자 하였다. A그룹(n=38)은 체질량 지수가 25 이하이며 관전압 100 kVp로 검사하였고 B그룹(n=45)은 체질량 지수가 25 이상이며 관전압 120kVp로 검사하였다. C그룹(n=37)은 체질량 지수가 25 이하이며 관전압 120kVp로 검사하였다. 체질량 지수가 25 이하로 낮은 A그룹(100 kVp)과 C그룹(120kVp)의 두 그룹간 평균 선량의 차이는 214.8 mGy·cm의 차이를 나타내었으나 정성적 평가에서는 큰 차이가 없음을 확인할 수 있었으며 체질량 지수가 25이상인 환자군과 비교하여서는 오히려 좋은 결과를 확인할 수 있었다. 따라서 체질량 지수가 25 이하로 낮은 환자는 관전압을 100 kVp 로 낮추어 촬영하여도 영상의 질에는 부정적인 영향을 주지 않음을 알 수 있다.

본 연구는 신체활동과 심리수정을 토대로 한 비만관리 프로그램이 남자비만청소년들의 체중감소와 신체 활동수준 및 심리적 변인을 변화시키는데 효과가 있는지를 확인하는데 그 목적을 두고 수행되었다. 서울시 N구에 소재한 C중학교 남학생중, 체질량이 25kg/m2인 비만학생 86명이 자발적으로 비만관리 프로그램에 참여하였다. 비만관리 프로그램은 12주간 줄넘기 운동 (주 3회)과 심리수정 전략(주 2회)으로 구성되어 있으며, 1회 40분씩 실시되었다. 여가시간 신체활동 질문지, 운동자신감 질문지, 의사결정균형질문지가 연구참여자들의 신체활동 및 관련된 심리적 변인의 변화를 측정하기 위하여 사용되었다. 연구 참여자들의 일반적 특성은 기술분석에 의해 제시되었으며, 비만관리 프로그램의 효과를 검증하기 위하여 반복측정분산분석이 수행되었다. 비만청소년들의 체질량은 비만관리 프로그램을 통해 유의하게 감소 하였고 (F=4.89, p=.007), 신체활동량은 유의하게 증가하였다 (F=3.87, p=.025). 또한, 비만청소년들의 신체활동 자신감(F=4.38, p=.016)과 신체활동이득에 대한 지각 (F=4.07, p=.021)은 유의하게 증가한 반면, 신체활동의 지각된 장애요인 (F=4.15, p=.023)은 유의하게 감소하였다. 본 연구는 비만과학 및 운동과학 영역에서 비만관리 프로그램을 계획하고 적용하는데 있어 신체활동 뿐만 아니라, 신체활동에 영향을 주는 다양한 심리적 특성의 중요성을 고려하여야 한다는 것으로 제안한다.
