The purpose of this study was to investigate the body mass index and food habits of female university students (nutrition majors) in Seoul. The means of height, weight and BMI were 161.22${\pm}$4.63cm, 52.76${\pm}$6.59kg, and 22.20${\pm}$3.98, respectively. Subjects were divided into 3 groups based on BMI. The ratio of underweight, normal, and overweight students was 25.2%, 56.3%, and 18.5%. respectively. There were significant differences in the recognition rate of body shape and the way to maintain health by BMI. And self satisfaction rate of body shape was significantly higher in underweight subjects compared with others. There was no significant difference in the rate of activity and exercise, food behavior, intake frequency of various foods, intake of convenience food and carbonated drink according to BMI. Weight and body fat of subjects had a significant correlation with BMI. and height, frequency of taking food, frequency of meals, food behavior, intake food, health and exercise consciousness rate showed no correlation with BMI.

PURPOSE: The coexistence of age-related skeletal muscle mass loss and obesity poses a substantial health risk for individuals because it combines the detrimental effects of muscle mass reduction associated with aging and the health complications from obesity. This study aimed to identify the incidence rate and key influencing elements among Korean men in their thirties. METHODS: A cross-sectional study involving 934 male participants was performed using complex sampling analysis. Various influencing elements were investigated, including age, height, weight, body mass index, waist circumference, skeletal muscle mass index, smoking and drinking behaviors, systolic and diastolic blood pressure, fasting glucose levels, triglyceride, and cholesterol levels. RESULTS: The incidence rate was 2.90%. The key influencing elements were age, height, weight, body mass index, waist circumference, skeletal muscle index, systolic blood pressure, fasting glucose, triglyceride, and total cholesterol (p < .05). CONCLUSION: This study identified the incidence rate and key influencing element for CALSMO among Korean younger community-dwelling men.

Purpose: This study aimed to investigate the clinical and metabolic determinants of circulating soluble leptin receptor (CSLR) and free leptin index (FLI) in pre-pubertal obese male children. Methods: We conducted a preliminary cross-sectional study at three tertiary hospitals and one public primary school. Eighty obese male children without growth and developmental abnormalities aged 5-9 years were recruited. In these children, obesity was solely caused by excessive food intake, and not by acute illness, medications, endocrine abnormalities, or any syndrome. Body mass index (BMI), body fat mass, carbohydrate intake, fat intake, high density lipoprotein cholesterol level, low density lipoprotein cholesterol level, triglyceride level, and Homeostatic Model Assessment for Insulin Resistance are the potential determinants for leptin regulation, which is represented by CSLR level and FLI. Results: Carbohydrate was the main source of energy. BMI and body fat mass had negative weak correlation with CSLR and positive weak correlation with FLI. Furthermore, carbohydrate intake was found to be independently associated with CSLR based on the results of the multiple linear regression analysis. Following an increase in carbohydrate intake, CSLR level decreased progressively without any negative peak. Conclusion: Leptin regulation in prepubertal obese male children is associated with body composition and dietary intake. Carbohydrate intake is useful for predicting CSLR. Lipid profiles and insulin resistance are not related to both CSLR and FLI. Treatment and prevention of leptin resistance in obese children should focus on reducing BMI, fat mass, and carbohydrate intake.

Objectives: The intention of this study was to find out the impact of mother's body mass index, eating habits, nutrition status and sociodemographic factors on the body mass index of the children. Methods: The study used original data of Korea National Health and Nutrition Examination Survey (2010-2011) and had 957 children in the ages of 1-5 years and 957 mothers of these children, a total 1,914 as subjects. The weights (body mass indexes) of the children, subjects under 5th percentile were classified into a underweight group, 5~84th percentile into a normal weight group, 85-94th percentile into an overweight group and more than 95th percentile into an obesity group based on the 2007 Korean children and adolescents growth chart. Results: We observed that when the body mass index of a mother increased by 1, the possibility that her child would belong to the overweight group increased by 6.5% (95% confidence interval: 1.01~1.13), and the possibility that the child would belong to the obesity group increased by 95% (confidence interval: 1.01~1.18). With regard to the number of deficient nutrients which were ingested according to estimated average requirements (EAR) amid nutrients ingested by the mother increased by 1, the possibility that the child would belong to the obesity group increased by 16.6% (95% confidence interval: 1.01~1.35). In case the birth weight of child increased by 1kg, the odds ratio that the child would belong to the obesity group was 2.022 (95% confidence interval: 1.08~3.77). Conclusions: We conclude that the body mass index, eating habits and nutrition status of the mother had significant effects on the body mass index of the child. Therefore, it is critical to recognize the importance of this observation and provide practical training for eating habits and nutrient intakes in order to achieve healthy growth and prevention of obesity among children.

The purpose of this research was to investigate nursing students' attitude toward body weight control, food behaviors according to their recognition, satisfaction on body image and Body Mass Index(BMI). The subjects were 273 nursing students. A survey was conducted using a self administered questionnaire. The data were an analyzed by a SPSS program. The majority of the surveyed participants were normal range for body mass index(BMI). Most of nursing students preferred a thin body image and were not satisfied with their body image. Most also controlled their body weight for appearance by exercising and the other efforts to change the body weight. From the above results, it is considered that nursing students need to establish proper self-recognition and dietary behaviors for their body images and counseling for desirable body weight control methods.

Purpose: The purpose of this study was to examine the effects of auricular acupressure on reducing obesity in adult women with abdominal obesity. Methods: The study design was a non-equivalent control group pretest-posttest design. Participants were 58 women, aged 20 years or older, assigned to the experimental group (n=30) or control group (n=28). Auricular acupressure using vaccaria seeds was administered to the experimental group. The sessions continued for 8 weeks. Outcome measures included body weight, abdominal circumference, and body mass index, body fat mass, body fat percentage, triglyceride, total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol, and serum glucose. Results: Women in the experimental group showed significant decreases in body weight (t=6.19, p<.001), abdominal circumference (t=4.01, p<.001), and body mass index (t=2.58, p=.006) after 8 weeks compared with those in the control group. Conclusion: Results show that auricular acupressure using vaccaria seeds was effective in decreasing body weight, abdominal circumference, body mass index, and triglyceride levels in adult women with abdominal obesity.

Background: There are many mechanisms in which stress can lead to weight gain thus high a BMI. The endocrine and inflammatory pathway can directly increase abdominal adiposity. Another way in which stress leads to weight gain is through changes in health behaviors. The study aimed to investigate the prevalence of musculoskeletal disorders (MSDs) among healthy students of Ahlia University, and to determine the relationship between the development of MSDs and academic stressors and body mass index. Methods: Self-administered questionnaires were distributed to 94 students aged 18-26 years who were enrolled at various Ahlia University colleges and met other inclusion criteria. The students responded to the standardized Nordic musculoskeletal questionnaire and the modified College Student Stress Inventory regarding musculoskeletal symptoms and academic stressors. Height and weight measurements were also obtained to determine body mass index. Results: A total of 77.66% reported MSDs in one or more body part, with the prevalence being higher among women than among men. The 7-day prevalence of MSDs severe enough to interfere with activities of daily living was 60.64%, and 44.68% by female and male students, respectively. There was a significant relationship between academic stress and MSDs in the neck, shoulders, lower back, and hips, while the relationship between MSDs, and body mass index, academic stress, and grade point average was not significant. Conclusions: The prevalence of MSDs among Ahlia University students was found to be high. Apart from the positive correlation between academic stress and MSDs in certain body parts, other correlations were not significant.

This study was conducted to determine the relationship between the body fat percent (BF%) and body mass index (BMI) of Koreans and the differences with Caucasians. Complete data were collected from 3297 subjects (2441females and 856 males) between the ages of 18 and 79. Data were collected between September 2001 and November 2001 in Seoul and Pusan. For the statistical analysis, only the data on subjects between the ages of 18 and 65(3200) were used Body weight and height were measured BMI (kg/$m^2$) was computed From BMI, BF (%) was calculated using age- and sex-specific prediction formulas. BF% was assessed using an INBODY 2.0 body fat analyser. Data analysis showed that the females were significantly younger than the males, were smaller, lighter and had a lower body mass index. Body fat percent of the females was higher than that of the males. 1he differences between actual measured BF% and BF% as predicted from prediction equations from the literature, based on BMI, age and sex, were correlated with level of body fat and age. There is a significant age-related decrease in body fat in Koreans for any given BMI and sex, which is remarkably different compared to age-related increases in body fat in the European reference group. For the same age and BF%, Korean females have a slightly lower BMI than their European counterparts. Korean males have, for the same age and BF%, a higher BMI than their European counterparts. The differences between females and males were not significant. It was concluded that, assuming that the data on body fat percent was correct, that the relationship between BF% and BMI is quite different in Koreans than in European Caucasians. Thus, for younger Koreans cut-off values for obesity should be slightly lower than those for Caucasians whereas for older Koreans the cut-off points for obesity should be higher than those for Caucasians.

Background: The purpose of this study was to identify weight control behavior according to body mass index and perception of body-image, and factors that affect weight control behavior in female college students. Methods: A convenience sample of 276 female college students agreed to complete a questionnaire. Data were collected from October 5 to October 15, 2009. The data were analyzed using SPSS win 18.0 program with descriptive statistics, Chi-square test and Logistic regression. Results: According to preferred body type, 86.9% of the students who preferred slim, 13.3% who preferred their own body type, and 4.2% who preferred chubby reported using weight control behavior. For weight control behavior according to satisfaction with body type, 82.9% of the students who were dissatisfied with their body type and 52.8% who were satisfied practiced weight control behavior. Variables influencing weight control behavior were body mass index (underweight OR 1.37, p=.050), cognition of the body (chubby/fat OR 2.68, p=.047), and preferred body type (slim OR 1.29, p=.006). Conclusion: The results of this study indicate that, health providers need to educate female college students about appropriate body image and weight control behavior. Also, more studies are needed to identify other factor influencing weight control behaviors.

PURPOSE: This study examined the distribution dynamics and proposed determinants, including morphological measurements, clinical laboratory tests, and lifestyle factors among young Korean men aged 20 to 29 years with the coexistence of age-related loss of skeletal muscle mass and obesity (CALSMO). METHODS: Six hundred and sixty-six participants were divided into two groups based on their skeletal muscle mass index, with 12 individuals categorized in the CALSMO group and the remaining 654 in the normal group. The proposed determinants variables consisted of three main components: morphological measurements, clinical laboratory tests, and lifestyle factors. The morphological measurement variables were height, weight, body mass index, waist circumference, and skeletal muscle mass index. The clinical laboratory tests were fasting glucose, triglyceride, total cholesterol levels, and systolic and diastolic blood pressure. The lifestyle factors considered were alcohol consumption and tobacco use. Complex sampling analysis was performed for the evaluation. RESULTS: The distribution dynamics were determined to be 1.81(1.02-3.18) %. Morphological factors, such as height, weight, body mass index, waist circumference, and skeletal muscle mass index, showed significant differences (p < .05). The clinical laboratory test variables, specifically the fasting glucose, triglyceride, and total cholesterol levels, also exhibited significant differences (p < .05). The lifestyle factor, alcohol consumption, also showed a significance (p < .05). CONCLUSION: This study provides insights into the distribution dynamics. The proposed determinants in young Korean individuals with CALSMO are height, weight, body mass index, waist circumference, skeletal muscle mass index, fasting glucose, triglyceride, total cholesterol levels, and alcohol consumption.
