The objective of this study was to assess the relationship between dietary sodium intake and prevalence of abdominal obesity in Korean adults. We used data from the Korea National Health and Nutrition Examination Survey V-1 and analyzed data on 4,475 Koreans (${\geq}30$ years old). Subjects were divided into three groups according to fasting plasma glucose (FPG): 1) normal (FPG <100 mg/dL), 2) pre-diabetes ($100mg/dL{\leq}FPG{\leq}125mg/dL$), and 3) diabetes (FPG ${\geq}126mg/dL$ or subjects diagnosed with diabetes). The subjects in each category were stratified by dietary sodium intake as well as index of abdominal obesity. We found that dietary sodium intake was positively correlated with waist circumference (WC) (P=0.002) and was particularly high in the pre-diabetes group. In multiple logistic regression analysis, the normal and diabetes groups showed no association between dietary sodium intake and WC, whereas the pre-diabetes group with a high sodium intake exhibited a significant association (odds ratio (OR)=1.479, P=0.029) between dietary sodium intake and WC. Further, the OR for abdominal obesity in the high sodium intake group with pre-diabetes was 1.590 after adjusting for age and sex (P=0.012). In addition, the ORs for the prevalence of abdominal obesity with fasting glucose, fasting insulin, and homeostasis model assessment of insulin resistance were significantly higher in the pre-diabetes group with high sodium intake compared with low sodium intake. Moreover, these associations were significant even after adjusting for confounding variables (model 2: age and sex; model 3: age, sex, and total energy intake). Our results suggest a strong association between sodium intake and abdominal obesity in pre-diabetes Korean adults.

This helps plus-size consumers purchase ready-made clothes and improves fitness by analyzing the upper body shapes of abdomen-obese adult males; in addition, it creates a size system based on each size interval of obesity shapes. The criteria for the 572 male subjects surveyed were over 25 kg/㎡ of the BMI, over 90 cm of waist, and over 0.85 waist hip ratio. The results were as follows. First, the higher the age group, the higher the degree of abdominal obesity in each age group. The degree of obesity decreases age increase; however, was the risk of abdominal obesity increased. Second, Compared to standard body types, the average body size of Abdomen-obese males is significantly larger, especially in the waist area than in the chest area. Third, to propose a size system for abdominal obese adult males, 16 sections with a final 2% rate of appearance were finally adopted as suit-tops size system for abdominal obese adult males by applying a 3 cm dimension gap between each designation as specified in the KS standard. The coverage ratio for the 16 sections was 72.6% and the coverage effienciency was 4.5%. The results of this study can be used in a various clothes; in addition, the activation and segmentation of the plus-size market are also believed to be significant.

This study was to investigate the effects of the body fat $\%$ on life styles and self-recognition of health conditions in hotel culinary college students. This survey was conducted using the questionnaires for 144 students (110 males, 34 female) in Hongseung-located college. More exercise time and less frequency of alcoholic beverage they intake, lowered their body fat $\%$. Males did stronger exercise and had lower body fat $\%$ than females. The stronger exercise they did, the lower body fat $\%$ they had, and were more satisfied with their present weight. Since they had more alcoholic beverage, they smoked more. Less smoking, more abdominal obesity they were. The less satisfaction with their body weights, the higher body fat $\%$ they had. The obese less were content with their weights. More recognition of obese shape, higher body fat $\%$ they had and abdominal obesity they were. Female had higher body fat $\%$ and were more abdominal obesity, did weak action, less smoke and weak exercise than male. Higher body fat $\%$ they had, more abdominal obesity they were. The more part time jobs they had, they did not smoke or were not satisfied with their body weights. Female students in culinary arts division had higher body fat $\%$ and were dissatisfied with their body weights and did less exercise or subnormal exercises.

We investigated coffee consumption in relation to the abdominal obesity as defined by waist circumference in Korean women aged 19~64 years, using data from the National Health and Nutrition Examination Survey 2012~2016. The participants to the study were classified according to 3-in-1 coffee consumption level (none-coffee, ${\leq}1$ time/day of 3-in-1 coffee, >1 time/day of 3-in-1 coffee) by a food frequency questionnaire. The analysis was conducted by the following age groups: <50 years and $50{\leq}$ years. The 3-in-1 coffee consumption group had significantly more smokers and more alcohol consumption frequency as compared to the none-coffee group. The energy intake from the participants in the 3-in-1 coffee consumption of ${\leq}1$ time/day of 3-in-1 coffee group, and >1 time/day of 3-in-1 coffee group were 131.2 kcal/day and 123.1 kcal/day. In the 50 years or over age group, >1 time/day of 3-in-1 coffee group was at a lower risk of abdominal obesity as defined by waist circumference, compared with the non-coffee group multivariable adjustment (OR: 0.44, 95% CI: 0.25~0.77). Our findings suggest that the 3-in-1 coffee consumption may be related to abdominal obesity as defined by waist circumference in Korean females aged 50 years or over.

The aim of this study is to investigate the effect of pharmacopuncture combined thread implantation therapy for treating localized obesity. The study was conducted on 3 subjects with abdominal localized fat, 1 subject with thigh and 1 subject with calf localized fat. We practiced two kinds of pharmacopunture, which were cultivated wild ginseng and contacting Ephedra sinica pharmacopuncture. In addition, we practiced thread implantation to 20 points on muscle membrane layer. We performed these treatments once in 2 weeks, totally for 3 times. After treatments, abdominal circumference and waist-hip ratio were reduced by 4.6 % and 0.13, respectively. In addition, circumferences of thigh and calf were reduced by 5.8 % and 4%. We supposed that this combined therapy could be useful to deal with localized fat deposit. Long-term evaluation and further studies are required to identify effect size of this therapy.

Objectives : This study was aimed to show the effect of electroacupuncture combined with magnetic acupuncture on abdominal obesity without patient dieting, exercise or use of herbal medication. Methods : Women over 85 cm in waist circumference were treated with electroacupuncture combined with magnetic acupuncture. Acupuncture points were located at the abdomen ($CV_{12}$, $CV_6$, $ST_{25}$, $ST_{21}$, $SP_{15}$, $SP_{14}$), extremities ($LI_4$, $LI_{11}$, $ST_{36}$, $ST_{44}$) and were stimulated 30 minutes with 2.1~3 Gaus, 500 Hz, tolerable strength. The Interference wave forms were by Whata 153 (Medi Lab, Korea). Two or three treatment sessions per week (five or ten sessions in total) were done. Before treatment, and after the last treatment, we measured waist circumference, hip circumference, waist hip ratio, thickness of abdominal subcutaneous fat, body weight, body mass index, body fat ratio, visceral fat area, free fat mass, body fat mass and skeletal muscle mass. We also measured the subcutaneous temperature of the abdomen($CV_{12}$, $ST_{25}(Rt)$, $ST_{25}(Lt)$, $CV_6$) by using digital infrared thermal imaging(DITI). Results : In this study, significant reductions were shown in waist circumference, hip circumference, thickness of abdominal subcutaneous fat, body weight, body mass index, body fat ratio and body fat mass. There were no significant differences in waist hip ratio, free fat mass or skeletal muscle mass. There were also significant increases of the subcutaneous temperature on $CV_{12}$, $ST_{25}(Rt)$, $ST_{25}(Lt)$. Conclusions : From the above results, electroacupuncture combined with magnetic acupuncture might be an effective treatment for abdominal obesity.

Objectives : This study evaluated the efficacy of electroacupuncture therapy using an insulated needle in adults with abdominal obesity. Methods : This study was a randomized, double-blind, parallel-designed pilot trial. Sixteen participants eligible according to the inclusion and exclusion criteria were randomly divided into an insulated needle group and a control group. Insulated or common needles were inserted at acupoints located on the abdomen (CV12, CV6, ST25, ST27, SP15) and were electrically stimulated for 30 minutes (16 Hz, within tolerable strength). A total of 10 sessions of treatment were performed twice per week for 5 weeks. All participants were requested to maintain their usual diet and lifestyle. The outcome measures were waist circumference (WC), waist-to-hip ratio (WHR), and abdominal computed tomography (CT) of the total fat area (TFA), subcutaneous fat area (SFA), and visceral fat area (VFA). Results : A total of 12 participants divided into the insulated needle group (n = 5) and the control group (n = 7; common needle) were treated for 10 sessions and analyzed per-protocol (PP). WC decreased significantly after 10 sessions in both groups. The WC, TFA, SFA, and VFA of abdominal CT in the insulated needle group decreased more than in the control group; however, there were no significant differences in any parameter between the insulated needle group and the control group. Patients in the insulated needle group were more strongly stimulated with electrical stimulation than patients in the control group. Conclusion : Electroacupuncture using insulated needles in adults with abdominal obesity might be a more effective treatment than common needles. Additional studies are required to compensate for the limitations of this pilot study and to verify the results and efficacy.

Objectives: This study was conducted to analyze the effects of obesity and abdominal obesity in accordance with the elderly's food consumption frequency and patterns. Methods: The source of this study was based on raw data from the fifth Korea National Health and Nutrition Examination Survey (KNHANES V-1, V-2, V-3). The subjects of the elderly aged 65 and over 5742 people were in the final analysis. Results: The results of the study showed that the elderly's obesity and abdominal obesity were significantly affected by their sex, food consumption frequency, smoking, and spouses. Moreover, subjects without dinner consumption had 0.658 times lower possibilities of obesity. In addition, consumption of three meals a day will be obesity 0.771 times lower than that of one or two meals a day(OR=0.771, 95%CI=0.65-0.913). Conclusions: The goal of this study is to achieve a better understanding of the characteristics of obesity depending on the elderly's eating habits and finally to present the baseline data for the improvement of their dietary habits.

Background: In Korea, the prevalence of obesity has steadily increased, and the socioeconomic burden of obesity has increased along with it. In 2015, the National Health Insurance Service (NHIS) signed a memorandum of understanding with the Korean Society for the Study of Obesity (KSSO), providing limited open access to its databases so that the status of obesity and obesity management could be investigated. Methods: Using NHIS databases, we analyzed nationwide population-based studies for obesity using the definition of obesity (body mass index ${\geq}25kg/m^2$) in subjects over the age of 20. Age and sex standardization were used for all data. Results: The KSSO released the 'Obesity Fact Sheet 2016' using the 2006-2015 NHIS Health Checkup database. The prevalence of obesity steadily increased from 28.7% in 2006 to 32.4% in 2015, and the prevalence of abdominal obesity also steadily increased from 18.4% in 2009 to 20.8% in 2015. The prevalence of class II obesity steadily increased from 2006 to 2015, such that the total prevalence was 4.8% in 2015 (5.6% in men and 4.0% in women). The highest prevalence of obesity was found in Jeju Island, while the lowest prevalence was found in Daegu City. The highest prevalence of abdominal obesity was also found in Jeju Island, while the lowest prevalence was found in Gwangju City. Conclusion: Based on the Obesity Fact Sheet 2016, a strategy for reducing the prevalence of obesity is needed, especially in Korean men.

Purpose: Obesity has been associated with higher total blood mercury levels, based on animal studies; however, studies that focus on children and adolescents are lacking. We aimed to assess the association between total blood mercury levels and the incidence of overweight and abdominal obesity in Korean adolescents. Methods: The study population comprised 1,567 adolescents (793 boys and 774 girls; aged 10-19 years), who participated in the Korea National Health and Nutrition Examination Survey 2010-2013. We analyzed total blood mercury levels according to obesity status in all participants. Results: The geometric mean of total blood mercury levels was $1.93{\mu}g/L$. Participants with overweight ($2.20{\mu}g/L$) and obesity ($2.17{\mu}g/L$) had higher levels than those with normal weight ($1.86{\mu}g/L$, P<0.0001). The prevalence of overweight significantly increased with elevation of the total blood mercury quartile in both sexes. Increased incidence of abdominal obesity corresponding to increased total blood mercury level was observed in boys. After adjusting for covariates, those in the highest total blood mercury quartile were found to be at higher risk of overweight/obesity than those in the lowest quartile in both sexes (odds ratio [95% confidence interval]: boys, 3.27 [1.66-6.41]; girls, 1.90 [1.03-3.49]). The association between total blood mercury quartile and abdominal obesity was significant after controlling for covariates in boys (2.35 [1.05-5.24]). Conclusion: Our results suggest an association between total blood mercury levels and overweight in Korean adolescents.
