Objectives: This study compared the differences of postmenopausal women's bone mineral density in relation to the degree of obesity, metabolism index and dietary factors that affect bone mineral density. Methods: The subjects included in the study are 39 postmenopausal women of normal weight with body mass index less than $25kg/m^2$ and 32 postmenopausal who are obese. Anthropometry and biochemical analysis were performed and nutrient intakes and DQI-I were assessed. Results: Normal weight women were $56.03{\pm}3.76years$ old and obese women were $58.09{\pm}5.13years$ old and there was no significant difference in age between the two groups. The T-score of bone mineral density was $0.03{\pm}1.06$ in normal weight women and $-0.60{\pm}1.47$ in obese women and this was significantly different between the two groups (p<0.05). Blood Leptin concentration was significantly lower in normal weight women ($6.09{\pm}3.37ng/mL$) compared to obese women in ($9.01{\pm}4.99ng/mL$) (p<0.05). The total score of diet quality index-international was $70.41{\pm}9.34$ in normal weight women and $64.93{\pm}7.82$ in obese women (p<0.05). T-score of bone mineral density showed negative correlations with percentage of body fat (r = -0.233, p=0.05), BMI (r = -0.197, p=0.017), triglyceride (r = -0.281, p=0.020) and leptin (r = -0.308, p=0.011). The results of multiple regression analysis performed as the method of entry showed that with 22.0% of explanation power, percentage of body fat (${\beta}=-0.048$, p<0.05), triglyceride (${\beta}=-0.005$, p<0.05) and HDL-cholesterol (${\beta}=0.034$, p<0.01), moderation of DQI-I (${\beta}=-0.231$, p<0.05) affected T-score significantly. Conclusions: The results of the study showed that obese women have less bone density than those with normal weight women. In addition, the factor analysis result that affect bone mineral density showed that intake of fat is a very important factor. Therefore, postmenopausal women need to maintain normal weight and manage blood lipid levels within normal range. They also need to take various sources of protein and reduce consumption of empty calorie foods that have high calories, fat, cholesterol and sodium.

Objectives: A mobile health intervention program was provided for employees with overweight and obesity for 12 weeks, and a process evaluation was completed at the end of the program. We investigated participant engagement based on app usage data, and whether engagement was associated with the degree of satisfaction with the program. Methods: The program involved the use of a dietary coaching app and a wearable device for monitoring physical activity and body composition. A total of 235 employees participated in the program. App usage data were collected from a mobile platform, and a questionnaire survey on process evaluation and needs assessment was conducted during the post-test. Results: The engagement level of the participants decreased over time. Participants in their 40s, high school graduates or lower education, and manufacturing workers showed higher engagement than other age groups, college graduates, and office workers, respectively. The overall satisfaction score was 3.6 out of 5. When participants were categorized into three groups according to their engagement level, the upper group was more satisfied than the lower group. A total of 71.5% of participants answered that they wanted to rejoin or recommend the program, and 71.9% answered that the program was helpful in improving their dietary habits. The most helpful components in the program were diet records and a 1:1 chat with the dietary coach from the dietary coaching app. The barriers to improving dietary habits included company dinners, special occasions, lack of time, and eating out. The workplace dietary management programs were recognized as necessary with a need score of 3.9 out of 5. Conclusions: Participants were generally satisfied with the mobile health intervention program, particularly highly engaged participants. Feedback from a dietary coach was an important factor in increasing satisfaction.

This study was intended to evaluate the weight control program for 18 obese female college students during 9 weeks. The weight control program was composed of periodical counsel for self-control of dietary attitude and exercise with personal/group program. The female college students were average 21.3 years old and average 161.8 cm of height. The subjects were classified into 2 groups based on BMI: overweight group $25\le{BMI}<27$, obese group BMI$\ge$27. The subjects were average 71.56 kg of weight and $27.25 kg/m^2$ of BMI before they joined the program. The prompt of joining was less self-confidence for appearance. After 9 weeks, the overweight group lost their weight about 3.28 kg and also reduced 1.61 percentage of body fat. The obese group also lost their weight about 3.0 kg but reduced only 0.8 percentage of body fat. The serum levels of total cholesterol and LDL-cholesterol dropped significantly (p<0.05) in the overweight group. The $VO_2$ max inclosed 2.71 mL/kg/min in the overweight group. The obese group reduced caloric intakes from $109.2\%\;to\;86.5\%$ of RDA. The scores of dietary attitude such as eating speed, snack frequency, watching TV or reading during the eating were significantly increased (p<0.05) in obese group. These overall results suggest this program would be effective in self-weight control of overweight people. But the obese group assumed negative attitude in self-exercise program. So it is necessary to manage weight control programs, as considering obesity degree of subjects.

The purpose of this study was to evaluate the clinical significance of ultrasonographic classification of fatty liver in three grades. From June 2018 to April 2019, 1047 patients (818 males and 229 females) diagnosed as fatty liver among 3607 patients who underwent abdominal ultrasonography at Busan screening center. Ultrasonography was classified into three grades: Grade I (mild fatty liver), Grade II (moderate fatty liver), and Grade III (severe fatty liver) according to the degree of parenchyma texture, acoustic attenuation, Obesity index, hematological test, and metabolic syndrome. The average age of men in each sex increased with the increase of the fatty liver. Body mass index (BMI) and waist circumference were significantly increased in both men and women (p=.000). hematological analysis showed that AST, ALT, ${\gamma}-GTP$, TG, fasting blood sugar, and glycated hemoglobin were significantly different from each other (p<.05). In women, ALT, ${\gamma}-GTP$ and TG showed a significant difference with increasing fatty liver (p<.05). The prevalence of metabolic syndrome was significantly increased in both sexes as the grade of fatty liver increased (p=.000). Based on the results of this study, it is suggested that the use of ultrasound - guided fatty liver according to severity may be useful for the treatment and follow - up of fatty liver if the liver grade is divided in consideration of hematological variables and metabolic syndrome.

BACKGROUND/OBJECTIVES: College students are in a period of transition from adolescence to adulthood, in which proper dietary habits and balanced nutritional intake are very important. However, improper dietary habits and lifestyles can bring several health problems. This study was performed to investigate blood lipid profiles, blood aluminum and mercury in college students and the relationships among them. SUBJECTS/METHODS: The subjects were 80 college students (43 males and 37 females) in Gyeonggi-do. General characteristics, anthropometric measurements, blood pressure, blood lipids, SGOT, SGPT, and blood aluminum and mercury of the subjects were measured and analyzed, and their relationship was studied. RESULTS: The BMI was significantly higher in males, $23.69{\pm}3.20kg/m^2$, than in females, $20.38{\pm}2.37kg/m^2$ (P < 0.001). The blood pressure was significantly higher in males with $128.93{\pm}12.92mmHg$ systolic pressure and $77.14{\pm}10.31mmHg$ diastolic pressure compared to females with $109.78{\pm}11.97mmHg$ and $65.95{\pm}6.92mmHg$, respectively (P < 0.001). HDL cholesterol in males, $61.88{\pm}13.06mg/dl$, was lower than $64.73{\pm}12.16mg/dl$ in females, but other blood lipid levels were higher in males. Blood aluminum was significantly higher in males, $9.12{\pm}2.11{\mu}g/L$, than in females, $8.03{\pm}2.14{\mu}g/L$ (P < 0.05), and blood mercury was higher in males, $3.08{\pm}1.55{\mu}g/L$, than in females, $2.64{\pm}1.49{\mu}g/L$. The blood lipids showed positive correlation with obesity and blood pressure. CONCLUSIONS: The degree of obesity, blood pressure, triglycerides, and LDL cholesterol were higher in males, suggesting possible association with chronic disease incidence such as hyperlipidemia and hypertension. Thus, it is considered that a systematic health education is needed for college students, especially for males.

This survey was conducted from June 2004 to August 2004, through questionnaires given to 432 women aged ranging from 20 to 50 years, who were living in the Seoul metropolitan area. The questionnaires were designed to determine the physique, level of obesity and dieting survey as well as to uncover which diets were in fashion and their satisfaction degree. Dieting-related knowledge and dieting side effects were also investigated. The results were as follows: In dieting survey, as the age increased, dieting for health reason (52.3%) increased, whereas that for aesthetic reasons (32.6%) decreased (p<0.05). The most effective methods of dieting were exercise (50.2%) and diet (45.0%) regimens. In regards to exercise frequency, 46.5% for none, 23.5% for 1-2 times a week, suggesting that most respondents do not practice exercise for dieting purposes (p<0.05). Major source for dieting was shown to be obtained from relative family or friends (31.7%), newspapers or magazines (29.3%) and internet (14.9%). As the age decreased, information from the latter increased, whereas that from TV program (21.2%) decreased (p<0.05). Reasons for excess weight were bad eating habits (39.6%), lack of exercise (38.3%), pregnancy and childbirth (10.6%). In fad dieting, while organic foods and aerobic exercises scored the highest satisfaction degree among diet and exercise regimens, on the other hand, sauna, steam baths and high temperature half-immersion baths scored the highest among surgery and other special therapies. As the age increased, the satisfaction degree for organic foods such as organic vegetable and high functional boiled cooked rice increased (p<0.05). As the age increased, scores on dieting-related knowledge decreased. Side effects of dieting included dizziness 06.2%) fatigue (15.1%) indigestion/constipation (11.1%) physical weakness 00.5%), loss of concentration (7.8%), dry skin (7.4%) loss of motivation (6.7%). The above results showed that attitude toward dieting among adult women varied with age and in light of the well-being trend, organic foods and aerobic exercises scored the highest satisfaction degree through all age.

Purpose: This study was planned to determine the characteristics of extremely obese patients during Bariatric surgery and to evaluate how the difference in the number of postsurgical personal nutritional educations they received affected the weight loss. Methods: This is a retrospective study on the basis of the medical records of extremely obese patients for 15 months after receiving gastric banding. A total of 60 people were selected as the study subjects and they were divided into the Less Educated Group and the More Educated Group according to the average number of personal nutritional educations they received. We investigated both groups to determine the general characteristic, health related lifestyle habits, obesity related complications and symptoms in possession, and eating habits before their surgery, the body composition measurement result, obesity determination indices at 1, 3, 6, 9, 12, and 15 months before and after their surgery, and the biochemical parameters at 6 months before and after their surgery. Results: Body fat and weight showed rapid reduction until 6 months after the surgery, but thereafter reduced slowly depending on the result of body composition measurement. Regarding body fat and weight, the More Educated Group, who received nutrition education more often, showed significantly lower levels than the Less Educated Group at 15 months after surgery. Regarding BMI and degree of obesity, the More Educated Group showed significantly lower levels than the Less Educated Group at 15 months after surgery. Here, we were assured that BMI is reversely proportional to the number of personal nutritional educations at 15 months, which is more outstanding after surgery than before surgery. Conclusion: Long-term nutritional education is a key factor for the extremely obese patient in maintaining the effects of Bariatric surgery on weight and body fat reduction onwards. In the next stage, considering the characteristics of the study subjects, adoption of individual nutrition education is recommended for postsurgical prospective arbitration of obesity in order to monitor blood pressure, obesity related complications, symptoms in possession, and how eating habits and health related life habits change, and to judge the actual effect of the nutritional education method at the same time.
