Purpose: Sodium is essentially required for homeostasis and physiological functions, but excessive sodium consumption increases the risk of obesity and other chronic disorders. Korean studies on the sodium-obesity relationship are limited, and thus, this study was undertaken to determine the nature of the relationship between sodium intake and obesity in Korean adults. Methods: Forty-two participants were divided into 2 groups according to body mass index (BMI, non-obese BMI < 25 kg/m², obese BMI ≥ 25 kg/m²). Dietary intakes and eating habits were analyzed using 3-day food records and a food frequency questionnaire. Anthropometric data were obtained from bioimpedance results, and fasting glucose and lipid levels were measured. Results: Mean weight, BMI, waist and hip circumferences, and body fat mass were greater in the obese group than in the non-obese group for men and women. Skeletal muscle mass and body fat mass were higher in obese women than in non-obese women. Biochemical data were no different in these two subgroups except triglycerides (TGs), which were higher in obese women. Nutrient intakes were not significantly different in obese and non-obese groups. However, obese men consumed excessive sodium, while obese women consumed slightly more than non-obese women. Obese men preferred salty foods and tended to overeat. Positive correlations were found between sodium intake and weight in men and percent body fat mass (PBFM) in women. Correlation analysis (adjusted for energy intake) of the relation between sodium intake and obesity-related factors showed sodium intake was positively correlated with PBFM and TG in women. Conclusion: This anthropometric and biochemical data analysis emphasizes the need for awareness and interventions to mitigate the health risks of elevated sodium consumption. Our findings should aid future studies on the relationship between sodium and obesity and contribute to preventing and managing this metabolic condition.

Purpose: The purpose of this study was to examine physical activities and health belief in order to provide basic data on obesity prevention and management among elementary school students based on the health belief model. Methods: Participants included 194 fifth grade students in an elementary school located in Seoul. Data were collected by questionnaires and physical measurement, including weight and height. The SPSS Win 17.0 program using descriptive statistics, ANOVA with Scheff$\acute{e}$ post hoc tests, and Cronbach's alpha coefficients was used in data analysis. Results: Significant differences were observed in physical activity according to perceived severity (F=3.444, p=.034), perceived benefit (F=7.674, p=.001), perceived barrier (F=21.014, p<.001), and self-efficacy (F=22.098, p<.001). A significant difference in physical activity (t=4.502, p<.001) and perceived severity (t=-2.278, p=.024) was observed according to gender. Significant differences in physical activity (t=7.633, p=.006), perceived barrier (t=10.826, p=.001), and self-efficacy (t=5.928, p=.016) were observed according to obesity status. Significant differences were observed in physical activity (F=7.503, p=.001), perceived susceptibility (F=37.904, p<.001), and perceived barrier (F=3.425, p=.035) depending on level of satisfaction with body image. Conclusions: In order to promote physical activity among children with low physical activity, development of program with an emphasis on the benefits of physical activity and physical activity self-efficacy, and to decrease the barriers to physical activity is needed.

Purpose: The purpose of this study was to offer basic data concerning the prevention of obesity for obese children to identify the relationship between their self-efficacy and the degree of performance on health promoting lifestyle profile. Method: The subjects were 148 fourth to sixth grade elementary school students in Gwang-ju, Korea during the period from September 10 to September 25, 2001. The collected data were analyzed by mean, standard deviation, t-test, ANOVA, Pearson's Correlation Coefficient and Stepwise Multiple Regression by using the SPSS program. Result: The relationship between general characteristics of subjects and self-efficacy were significant differences according to eating time(F=5.338, p=.006). The relationship between general characteristics of subjects and health promoting lifestyle profile were significant differences according to grade(F=5.615, p=.005), eating time(F=8.591, p=.000), concern about weight control(F=3.915, p=.022), experience of weight control(t=7.632, p=.006). Health promoting lifestyle profile was showed significant positive correlations with self-efficacy(r=.537, p=.000). Self-efficacy(27.6％) was the highest factor predictor health promoting lifestyle profile of obesity students. In addition to eating time, concern about weight control, explained for 33.3％ in health promoting lifestyle profile. Conclusion: Results of this study point to self-dfficiency as a major factor in the health promoting behavior of childhood obesity. According to the results of this study, There is a reason to develop a health program to promote self-efficiency.

Lipid accumulation in white adipose tissue is the key contributor to the obesity and orchestrates numerous metabolic health problems such as type 2 diabetes, hypertension, atherosclerosis, and cancer. Nonetheless, the prevention and treatment of obesity are still inadequate. Recently, scientists found that brown adipose tissue (BAT) in adult humans has functions that are diametrically opposite to those of white adipose tissue and that BAT holds promise for a new strategy to counteract obesity. In this study, we evaluated the potential of sinapic acid (SA) to promote the thermogenic program and lipolysis in BAT. SA treatment of brown adipocytes induced the expression of brown-adipocyte activation-related genes such as Ucp1, Pgc-1α, and Prdm16. Furthermore, structural analysis and western blot revealed that SA upregulates protein kinase A (PKA) phosphorylation with competitive inhibition by a pan-PKA inhibitor, H89. SA binds to the adenosine triphosphate (ATP) site on the PKA catalytic subunit where H89 binds specifically. PKA-cat-α1 gene-silencing experiments confirmed that SA activates the thermogenic program via a mechanism involving PKA and cyclic AMP response element-binding protein (CREB) signaling. Moreover, SA treatment promoted lipolysis via a PKA/p38-mediated pathway. Our findings may allow us to open a new avenue of strategies against obesity and need further investigation.

The purpose of this study was to suggest torso patterns that fit the three main body shapes of elderly obese women. To reduce time, costs, and also the trial and error needed to make patterns, the CLO program for 3D test wear was employed. Three virtual models for aged obese women were use, with the YUKA system used to produce torso patterns. 3D simulation of test wear and corrections was done to design optimal torso patterns. The results were as follows: First, for the three models of obese women's body shapes as realized by CLO 3D, Type 1 is lower-body obesity shapes, Type 2 is abdominal obesity shapes, and Type 3 is whole-body obesity shapes. Second, to design the study patterns, actual measurement values, back waist length and waist to hip length, were used. The armhole depth (B/4-1.5), front interscye (B/6+2.3), front neck width (B/12-0.5), front neck depth (B/12+0.5), front waist measurement (W/4+ 1.5+D), front hip measurement (H/4+2+0.5), and back hip measurement (H/4+3-0.5) were calculated using formulas. Third, according to the results of test-wearing the study patterns, reduced front neck width and depth improved the neck fit and reduced armhole depth bettered loose or plunging armhole girth and also reduced the sagging of bust c.. Also, tight sidesfrom aprotruded waist and abdomen improved with the increase of surpluses in the back waist and also back and front hip c. The exterior was enhanced by displacement of back and front darts, which distributed surpluses better.

Rapid shift to western dietary patterns and social drive of thinness would lead to increase the likelihood of developing eating disorders. This study was performed to analyze the associated factors between dietary pattern and self visualization in terms of body shape, which may increase the risk of disturbed eating attitudes among high school students in Korea. A cross-sectional study was conducted from 2009 to 2010 for high school students including both male and female students, from 6 schools in Gyunggi Province, Korea. A total of 766 students self-reported a questionnaire, including weight control practice, perceptions of self body image and ideal body image, dietary habit, and EAT-26 (Eating Attitude Test-26). Logistic regression analysis was used to fine the factors potentially associated with disturbed eating attitudes. Statistical analysis was conducted using SAS program (version 9.1). Results showed that disturbed eating attitudes were found in 8.7% of male high school students, and in 20.8% of female high school students. Experience of body weight control was reported by 56.2% of male students and by 87.3% of female students. According to multiple logistic regression analysis, obesity was independently associated with high risk of disturbed eating attitudes in male students [Odds Ratios (OR) 2.96, 95% Confidence Interval (CI) 0.90-9.71]. Body image dissatisfaction (OR 2.77, 95%CI 1.37-5.62) and extended family type (OR 2.70, 95%CI 1.05-6.90) were independently associated with high risk of disturbed eating attitudes, especially in female students. In conclusion, proper efforts in education for obesity and developing self-esteem to reduce the risks of disturbed eating attitudes should be implemented in high school nutrition program.
