In order to give basic data to teenager's healthcare, we investigated the food habits according to BMI (Body Mass Index), life style, dietary related self-efficacy and food intake through conducting a research surveying 732 middle school students of the Kwang-ju and Chonnam areas. The results of this study were compared groups in under weight (UW), normal weight (NW), and overweight (OW) groups according to BMI levels. In the male students, height was significantly differently in the UW group as $158.2\pm0.7$ cm compared to other NW and OW groups respectively as $163.7\pm0.6$ cm and $162.6\pm0.7$ cm but in the female students there was no significantly difference within groups. Weight was significantly different between the groups in the male students, whereas there were minor differences in the female students. The average of BMI was $20.7\pm0.1$ on the male students and $20.6\pm0.1$ on the female students which were all within the average, and their obesity was increased as the school grade was higher. Under less than 30,000 won of pocket money was dominating, and most of the students were in a nuclear family. In all male and female students, the inactive hours like watching TV and using computers had no differences between groups. The difference between groups was minor on breakfast time and most of the students thought their problems on unbalanced diet. There was significant difference in the OW group in female students as they thought their problems on unbalanced diets. The frequency of snack was significantly low in the OW group of male students but there were no differences in snack and eating-out food. All students chose fruits as snack food and Korean-style food as eating out food. The OW group in male students were significantly low in the dietary related self-efficacy when they were with their families and feeling depressed but there were no differences in female students between groups. When all students were getting higher BMI, they evaluated themselves badly in their self-dietary habits. Also the more male students had non-physical activity time, the less they had the dietary related self-efficacy and the more female students had physical activity time, the higher they had the dietary related self-efficacy. In conclusion, the OW group had good habits in physical activities for weekends, meal times, frequency of snack consumption but it showed undesirable when they were low in dietary related self-efficacy. Therefore we will provide the systematic nutrition education to them through this study.

Objectives: This study was conducted to investigate the association between health risk factors and mortality in Juam cohort. Methods: The subjects were 1,447 males and 1,889 females who had been followed up for 68.5 months to 1 January 2001. Whether they were alive or not was confirmed by the mortality data of the National Statistical Office. A total of 289 persons among them died during the follow-up period. The Cox's proportional hazard regression model was used for survival analysis. Results: Age, type of medical insurance, self cognitive health level, habit of alcohol drinking, smoking, exercise and BMI level were included in Cox's proportional hazard model by gender. The hazard ratio of age was 1.07(95% CI: 1.05-1.10) in men, 1.09(95% CI: 1.06-1.12) in women. The hazard ratio of medical aid(lower socioeconomic state) was 1.43(95% CI 1.02-2.19) in women. The hazard ratios of current alcohol drinking and current smoking were respectively 1.69(95% CI: 1.01-2.98), 1.52(95% CI: 1.02-2.28) in women. The hazard ratio of underweight was 1.56(95% CI 1.08-2.47) in men. The hazard ratios of underweight, normoweight, overweight, and obesity were respectively 1.63(95% CI: 1.02-2.67), 1.0(referent), 0.62(95% CI: 0.32-1.63), 1.27(95% CI: 0.65-3.06), which supported the U-shaped relationship between body mass index and mortality among the men over 65. Conclusions: The health risk factors increasing mortality were age, underweight in male, age, lower socioeconomic state, current alcohol drinking, current smoking in female. To evaluate long-term association between health risk factors and mortality, further studies need to be carried out.

Objectives: This study investigates the current state of consuming breakfast among elementary school students residing in Malang, East Java, Indonesia, and to identify factors that influence breakfast behavior. Methods: The research model was set up as per the health belief model, and slightly modified by adding the subjective normative factors of the theory of planned behavior. The survey was conducted from July 17 to August 15, 2017 using a questionnaire, after receiving the permission PNU IRB (2017_60_HR). Results: The subjects were 77 boys (49.4%) and 79 girls (50.6%) suffering from malnutrition with anemia (21.2%) and stunting ratio of Height for Age Z Score (HAZ) (11.5%). Furthermore, moderate weakness (14.8%) and overweight and obesity (12.3%) by Body Mass Index for Age Z Score (BMIZ) were coexistent. According to the results obtained for breakfast, 21.8% did not eat breakfast before school, with 18.8% of the reasons for skipping breakfast being attributed to lack of food. Even for subjects partaking breakfast, only about 10% had a good balanced diet. The average score of behavioral intention on eating breakfast was 2.60 ± 0.58. The perceived sensitivity, perceived severity, perceived benefits, and self-efficacy of the health belief model correlated with breakfast behavior. Of these, self-efficacy (β=0.447, R²=0.200) and perceived sensitivity (β=0.373, R²=0.139) had the greatest effect on breakfast behavior. Mother was the largest impact person among children. Conclusions: In order to increase the level of breakfast behavior intention among children surveyed in Indonesia, we determined the effectiveness by focus on education which helps the children recognize to be more likely to get sick when they don't have breakfast, and increase their confidence in ability to have breakfast on their own. We believe there is a necessity to seek ways to provide indirect intervention through mothers, as well as impart direct nutrition education to children.

BACKGROUND/OBJECTIVES: Increased consumption of instant noodles has recently been reported to be positively associated with obesity and cardiometabolic syndrome in South Korea, which has the highest per capita instant noodle consumption worldwide. This study aimed to investigate the association between instant noodle consumption and cardiometabolic risk factors among college students in Seoul. SUBJECTS/METHODS: The study subjects consisted of 3,397 college students (1,782 male; 1,615 female) aged 18-29 years who participated in a health checkup. Information on instant noodle consumption was obtained from the participants' answers to a question about their average frequency of instant noodle intake over the 1 year period prior to the survey. RESULTS: Statistical analysis using a general linear model that adjusted for age, body mass index, gender, family income, health-related behaviors, and other dietary factors important for cardiometabolic risk, showed a positive association between the frequency of instant noodle consumption and plasma triglyceride levels, diastolic blood pressure, and fasting blood glucose levels in all subjects. Compared to the group with the lowest frequency of instant noodle intake (${\leq}1/month$), the odds ratio for hypertriglyceridemia in the group with an intake of ${\geq}3/week$ was 2.639 [95% confidence interval (CI), 1.393-5.000] for all subjects, while it was 2.149 (95% CI, 1.045-4.419) and 5.992 (95% CI, 1.859-21.824) for male and female students, respectively. In female students, diastolic blood pressure was also higher among more frequent consumers of instant noodles. CONCLUSIONS: Our results suggest that frequent consumption of instant noodles may be associated with increased cardiometabolic risk factors among apparently healthy college students aged 18-29 years.

This study was carried out to investigate the body weight controls and eating disorders of university students in Gunsan. The subject of the present study included 229 male students (53.8%) and 197 female students (46.2%), totalling 426 students from Kunsan University. The subjects consisted of 56 underweight (13.1%), 265 with normal weight (62.2%), and 105 overweight (24.6%). Especially, in females, 20.8% of them were underweight, which is 6.6% higher than males, showing a significant difference (p<0.001). Regarding body image, 21.8% of the males thought they were fat, while 40.6% of the females thought they were fat. Regarding the perceived body type, shown in the difference between their own size and the ideal size, males recorded 0.03, while females recorded 1.75, showing a major significant difference (p<0.001). Regarding body satisfaction, 33.2% of the males were unsatisfied, while 52.8% of the females were unsatisfied (p<0.001). The social expectations of the male subjects' sizes and weights recorded 2.04, while that of females recorded -2.51, showing that people's opinions expected the female subjects' bodies to be thinner (p<0.001). Additionally, the social expectation of the subjects' weight control recorded an average of 15.22 (13.92 for males, 16.73 for females), showing that the female subjects' felt that people's opinions wished them to lose their weight (p<0.001). Regarding the recognition on weight control, interested males were 49.4%, while interested females were 86.8%, showing the females superior rate (p<0.001). The beliefs in relation to weight control recorded an average of 62.01, with the score of females of 67.89 being significantly higher than that of males which was 56.96. The subjects showed a relatively positive response towards weight control (p<0.001). EAT-26 score was employed to determine the eating attitudes in relation to gender. Here, the final score of males was 15.46, which was significantly lower than that of females, which was 22.21 (p<0.001). Furthermore, regarding the score of eating attitudes in relation to obesity index, the eating disorder scale scores on the questions related to bulimia and diets to lose weight as weight increases were high. However, the eating disorder scale score on oral control, which actually controls food, was low. To control the expansion of excessive weight control attempts and their side effects, the recognition of the students' body types needs to be corrected, and nutrition education programs on eating habits and eating disorders to foster proper weight loss are deemed necessary.

In previous studies, we performed joint animal studies and clinical trials between Yonsei University and Oryza Oil & Fat Chemical Co. Ltd. We have shown that coffee bean extract has potent anti-obesity and hypotriglyceridemic activities as well as beneficial effects on body fat reduction.In this study, the effects of coffee bean extract (100 mg/capsule) on body fat reduction were evaluated in overweight/obese women (body mass index of 25~30 $kg/m^2$ or body fat > 30%) not diagnosed with any type of disease. Subjects were randomly assigned to a coffee bean extract group (n=10) or placebo group (n=10). We measured anthropometric parameters, abdominal fat distribution by computed tomography and blood components before and after the 8week intervention period. After supplementation, the coffee bean extract group showed body weight (p=0.08), body mass index (p=0.06), hip circumference (p<0.05), and upper waist circumference (p< 0.01). In addition, after 8 weeks, the coffee bean extract group showed a significant decrease in abdominal internal fat area compared to 0 weeks (0 weeks : $155.8cm^2$; 8 weeks : $145.9cm^2$, ${\Delta}$ change : $-9.9cm^2$, respectively). However, there were no significant differences in lipid profiles or serological measurements between the coffee bean extract group and placebo group. The results of our human study demonstrated that coffee bean extract supplementation for 8 weeks has beneficial effects on reducing abdominal internal fat area as well as hip and waist circumferences.

식사장애(eating discorder)는 비교적 최근에 와서 관심과 흥미의 대상이 되었는데 최근 20년간 이들의 발생빈도의 증가 자체가 이 질병에 대한 전문적이거나 일반적인 관심의 증가를 가져왔다. 이러한 장애는 마른 것에 대한 지나친 욕망이 특징인 신경성 식욕 부진증(anorexia nervosa)과 살찌는 것에 대한 두려움이 특징인 신경성 대식증(bulima nurvosa)으로 나뉘어 진다. 이들 장애에 대한 역학사는 조사방법 및 대상에 따라 차이가 많으나 일반인에서의 신경성 식욕 부진증의 유병율은 $1.0\%\~4.0\%$정도이며 신경성 대식증은 $2\%$ 정도라고 보고되었고 우리나라에서는 일반 대학생을 대상으로 한 연구에서 신경성 식욕부진증이 $0.7\%$, 거식증이 $0.8\%$라고 보고한 바 있으며 이들은 대부분 식습관이 나쁘거나 식사태도 역시 나쁜 경향이 높다고 시사한 바 있다. <중략> 이에 본 연구에서는 식사장애의 유형들을 알아보고 신체적, 정신적으로 올바른 영양섭취와 성장이라는 중요한 시기에 있는 청소년들을 대상으로 식사장애에 대한 위의 두 가지 대표적인 경우를 혼합적으로 문항을 구성하고 이를 체크하여 언제나 확인할 수 있는 식사장애 자가진단 시스템을 구현해 보고자 한다.
