Objectives: This study was to investigate how body-shape perception could influence to weight control practice both in normal and obese group. Methods: We used 2012 Korea National Health and Nutrition Examination Survey to analysis 1) weight control practices of population; 2) consistency between body-shape perception and body mass index; 3) comparison weight control practices between normal group and body mass index (BMI) obese group in perceptional obese group; 4) odds ratio of BMI obese group using herbal drugs for weight control practice in perceptional obese group. Results: We found that study population tends to choose exercise, dietary restriction, meal skip, health functional food, one-food, drug, herbal drug, fasting and self-medication in order of frequency to control weight. The agreement between body-shape perception and BMI within obese group was approximately 64% with 0.40 of Cohen's Kappa coefficient, ranging from 0.384 to 0.423. Within perceptional obese group, choosing each weight control practice methods ratios between normal BMI group and obese BMI group were not significantly different. Within perceptional obese group, obese BMI group showed significant odds ratio (2.58, 95% confidence intervals, 1.38~4.85) than normal BMI group in choosing herbal medication for weight loss when adjusting other variables. Conclusions: We concluded that body-shape perception might be an important factor for choosing weight control program, and roles of Korean medical doctors thought to be enhanced for using herbal medication for weight loss.

AIMS: Korean National Growth Chart was newly developed at 2007. Prevalence of obesity is expected to be changed according to reference data. This study was performed to compare the prevalence of obesity based on the newly developed growth curve with that of previous data. We also investigate the incidence of obesity, overweight, and normal criteria by two kinds of growth curves. Method: We obtained weight, height from 438 middle school students and 1786 high school students. We divided enrolled students into four groups (middle school boys, middle school girls, high school boys, high school girls). The obese, over weight group was defined as BMI(body mass index) more than 95th, 85th${\sim}$94th percentile respectively for age and sex. Obesity by relative weight was defined more than 20% of ideal body weight. We compare the prevalence of obesity in each group by the newly developed Korean National Growth Chart in 2007 and that in 1998. Result: Prevalence of obesity by BMI based on 2007 Korean National Growth Chart and that in 1998 were 8.2-12.9% and 9.0-20.4% respectively. The concordance rate were 99.0%-100% in obese group and 45.0%-91.9% in overweight group according to two kinds of reference data. Prevalence of obesity by relative weight was 11.7-23.0% that was same between 2007 Korean National Growth Chart and that in 1998 except middle school boys group. Conclusion: We found that there is a decrease in prevalence of Obesity by BMI based on 2007 Korean National Growth Chart. It is necessary to evaluate correlation between criteria for obesity and obesity related comorbid conditions for finding proper BMI or relative weight cut off value to prevent obesity and obesity related complications effectively.

As obesity is known to be related to hyperlipidemia, insulin and leptin resistance, and other chronic diseases, much recent research has focused on functional food materials and their anti-obesity activity. This study was performed to study the effects of Artemisia Iwayomogi oligosaccharide AIPI on the anti-obesity function in normal rats and diet-induced obese (DIO) rats. F344 male rats were divided into four groups: Normal-control (CONT), normal-AIPI, DIO-CONT and DIO-AIPI. The groups were provided with water (in the CONT groups) or another drink for 4 weeks. The final body weights of rats in the DIO-AIPI group were lower than those in the CONT group. Abdominal adipose tissue weight per kg of body weight in the DIO-AIPI group was significantly lower than that in the DIO-CONT group. Also, the final levels of serum-triglyceride, serum-total cholesterol and serum-low density lipoprotein cholesterol in the DIO-AIPI group were lower than those in the DIO-CONT group. Moreover, the serum-high density lipoprotein cholesterol level in the normal-AIPI group was significantly higher than that in the normal-CONT group. Finally, the serum-leptin concentration was significantly lower in the DIO-AIPI group. Total lipid, triglyceride, and total cholesterol contents in the feces of the DIO-AIPI group were as high as 142％, 199％, and 165% of the respective values of the DIO-CONT GROUP. These results indicate that orally administered Artemisia Iwayomogi oligosaccharide not only has hypotriglycemic and hypocholesterolemic effects, but also has the effect of reducing the body weight and the abdominal adipose tissue weights obese rats. Therefore, we expect that Artemisia Iwayomogi oligosaccharide AIPI may have an anti-obesity function in F344 diet-induced obese rats. (Korean J Nutrition 36(5): 437∼445, 2003)

Objectives: The purpose of this study was to estimate the distribution and exposure prevalence of total carbohydrate intake and the carbohydrate-based foods such as rice, noodles, sweet potatoes, sweet drinks, milk and fruits and to characterize intake patterns among obese Korean adults. Methods: Subjects included 137,363 adults aged 40 years or older who participated in a Health Examinees (HEXA) Study. Multiple regression analysis of data from Semi-Quantitative Food Frequency Questionnaire (SQFFQ) identified food sources of carbohydrates. Weight, height and waist circumstance (WC) were measured, and the body mass index (BMI) was calculated. Obesity was defined as $BMI{\geq}25kg/m^2$ and abdominal obesity as $WC{\geq}90cm$ and ${\geq}85cm$ for males and females, respectively. Results: Obese adults appeared to have a higher total carbohydrate intake in the univariate analysis but had eaten less after adjustment for general and lifestyle factors, compared to normal weight adults (OR 0.78, 95% CI 0.73-0.82 for general obesity; OR 0.79, 95% CI 0.74-0.85, for abdominal obesity; P trend < 0.0001, respectively). Based on advance analysis for the food sources of carbohydrates, obese subjects had lower intake of rice (OR 0.86, 95% CI 0.68 -1.09 for general obesity; OR 0.87, 95% CI 0.67-1.13, for abdominal obesity; P trend < 0.0001, respectively) and higher intake of noodles (OR 1.21, 95% CI 1.16-1.27 for general obesity; OR 1.25, 95% CI 1.19-1.32, for abdominal obesity; P trend < 0.0001 respectively). With regard to other food sources of carbohydrates such as milk and fruits, intake was lower among obese compared to normal weight subjects. Conclusions: In the Korean middle-aged and older obesity groups, the intake of carbohydrates and the related foods was lower than in normal weight subjects, except for noodles. We conclude that a higher intake of noodles may enhance weight-gain. Therefore, this study suggested that the guidelines should consider the types of carbohydrate sources and the amount consumed from foods in order to provide proper guidance with regard to control and prevent obesity among Korean adults.

The purpose of this study was to understand the effects a mother's degree of obesity has on her daughter's obesity index, psychological well-being index, and nutrient intakes. The daughters, as study subjects, were classified into two groups according to their mother's body mass index (BMI): an obese group [BMI>25 kg/m$^2$, mother obesity group (MOG)] and a normal weight group [BMI<25 kg/m$^2$, mother normal weight group (MNG)]. The daughters in MOG showed significantly higher percent ideal body weight values than the daughters in MNG (p<0.001). MOG and MNG had significantly different psychological well-being index scores in terms of being classified into a highly stressed group (p<0.001), potentially stressed group (p<0.05), and healthy group (p<0.001). Intakes of daily energy, protein, fat, thiamin, riboflavin, niacin, phosphorus, and iron were also significantly different (p<0.001) between MOG and MNG. In particular, the vitamin A and C intakes of the MNG daughters were significantly higher than those of the MOG daughters (p<0.001). Overall, the results showed that a mother's level of obesity was essentially related to her daughter's obesity index, psychological well-being index score, and nutrient intakes. Therefore, it seems necessary for mothers to maintain an ideal body weight to prevent obesity and diet related problems in their daughters.

This study was carried out to investigate distribution of obesity, body composition, weight control and dietary behaviors, and to analyze the relationship between Body Mass Index (BMI) and physical characteristics, body composition and dietary behaviors by anthropmetric measurement and questionnaires. The 199 study subjects were divided into 3 age groups; 30's (78), 40's (77) and 50's (44) and 4 groups by BMI ; under weight (4.5%), normal (51.3%), over weight (26.1%) and obese (18.1%). Amount of skeletal muscle, body water, mineral and body fat were significantly increased with BMI. There were especially significant increase skeletal muscle 5.3 kg ($19.1\;{\rightarrow}\;23.5\;kg$), body water 5.3 kg ($26.3\;{\rightarrow}\;31.6\;kg$) and fat 15.2 kg ($11.2\;{\rightarrow}\;26.4\;kg$) from under weight to obesity group, respectively (p < 0.01). There were significantly decreased in the ratio of body water (10.3%), protein (2.7%) and body mineral (1.1%) from under weight to obesity, but significant increase 14.1% in body fat (p < 0.001). About 44.4% of under weight group and 40.1% of normal group and 50% of over and obesity group had dissatisfaction on their body images. Most of the women were concerned about their body images and experienced weight control. Dietary behavior scores of obesity group were significant lower than the other four groups (p < 0.001). There were significant positive correlation between BMI and body water (r = 0.62), protein (r = 0.52), skeletal muscle (r = 0.63), body fat (r = 0.91) and WH ratio (r = 0.91), respectively (p < 0.001). The correlation between BMI and body fat and WH ratio were much higher than the correlation between weight and fat and WH ratio.

Purpose: The purpose of this study was to identify the Health Promotion Life Profile of normal-weight and obese children, and factors related to obesity in elementary school children, and provide basic data for the development an obesity management program for these children. Method: The survey participants were 878 fourth to sixth grade elementary school children in Gwangju. $x^2$-test, t-test, ANOVA and multiple logistic regression with the SPSS program were used to analyze the collected data. Results: The Health Promotion Life Profile showed significant differences between normal-weight and obese groups according to food habits (t=3.305, p= .001) and exercise habits (t=-4.065, p=< .001). The Health Promotion Life Profile of obese children was also significantly different according to interest in weight control (F=3.044, p= .050), regular breakfast (F=3.699, p= .014), regular meals (F=6.868, p= .002). The multiple logistic regression analysis, showed that factors in obesity were significantly different according to gender, interest in weight control, fast eating, overeating and predilection for some food. Conclusion: The results of this study suggest that items on Health Promotion Life Profile such as food habits and exercise habits should be included in education programs to prevent obesity in elementary school children.

BACKGROUND/OBJECTIVES: The present study was conducted to investigate the effects of dried Momordica charantia aqueous extracts (MCA) and ethanol extracts (MCE) on obesity and lipid profiles in mice fed a high-fat diet. MATERIALS/METHODS: Forty two ICR mice were randomly divided into six groups. The normal group was fed a basal diet, and other groups were fed a 45% high-fat diet (HFD) for 7 weeks. The normal and HFD groups were also orally administered distilled water each day for 7 weeks. The remaining groups received Momordica charantia extract (0.5 or 1.0 g/kg/day MCA, and 0.5 or 1.0 g/kg/day MCE). In order to measure the anti-obesity and lipid profile improvement effects, body and visceral tissue weight, lipid profiles, plasma insulin levels, hepatic malondialdehyde (MDA) levels and superoxide dismutase (SOD) activity were measured. RESULTS: Both MCA and MCE significantly decreased body and visceral tissue weight relative to those of the HFD group (P < 0.05). Additionally high doses of MCE and MCA significantly reduced the plasmatic insulin levels compared to the HFD groups (P < 0.05) to concentrations comparable to those found in the normal group. MCA and MCE supplementation also significantly modulated the lipid profiles in plasma, liver, and feces compared to mice fed the HFD (P < 0.05). Furthermore MCA and MCE significantly increased hepatic SOD activity, and reduced MDA generation in the liver of the HFD mice (P < 0.05). CONCLUSIONS: Results from the present study suggest that Momordica charantia extracts have anti-obesity effects and the ability to modulate lipid prolife of mice fed a HFD by suppressing body weight gain, visceral tissue weight, plasma and hepatic lipid concentrations, and lipid peroxidation along with increasing lipid metabolism.

Objective: Ramulus mori (RM) has been known to be effective for the treatment of obesity. To show the effectiveness of RM in a more scientific way, RM extract was prepared and evaluated in high fat diet rats by measuring the changes of body weight and lipid metabolism as described briefly below. Methods: 200 g of crushed RM was extracted withmethyl alcohol. The extract was evaporated under reduced pressure to give 33.4 g. For 10 weeks, control group rats were fed a high fat diet, while the test group rats were fed with the same diet plus RM extract. The normal group was fed with a normal diet. 150 mg of RM extract per 1 kg of body weight was added to the diet in the test group rats. Results: The control group rats on the high fat diet gained weight significantly, whereas the test group rats on the high fat diet plus RM extract gamed less weight. The significant increase of liver weight caused by the high fat diet was also inhibited by the RM extract treatment. Total lipid, triglyceride and total cholesterol levels of serum in the high fat diet rats were remarkably increased, whereastheir levels on the high fat diet plus RM extract were less increased. While serum HDL-cholesterol levels were remarkably decreased in the high fat diet, its level was less decreased in the high fat diet plus RM extract. Furthermore, we observed that the activities of hepatic acetyl-CoA carboxylase and fatty acid synthetase increased under the high fat diet, while their activities under the high fat diet plus RM extract were getting back nearly to the normal levels of the normal diet rats. Conclusions: These result show that the obesity caused by a high fat diet was effectively inhibited by an RM extract. Our results also showed that the abnormal lipid metabolism caused by a high fat diet was effectively cured by adding RM extract.

Objectives: This study was performed to evaluate the effects of fermented Samjung-hwan (SJH) extracts on weight, serum lipids and blood glucose. Methods: SJH was fermented using three different probiotic bacterial strains (Lactobacillus plantarum [LP], Leuconostoc mesenteroides [LM], Bifidobacterium longum [BL]) separately. Thirty-six rats were divided into normal, control (high fat diet), SJH-UF (high fat diet+unfermented SJH 200 mg/kg), SJH-LP (high fat diet+LP fermented SJH 200 mg/kg), SJH-LM (high fat diet+LM fermented SJH 200 mg/kg) and SJH-BL (high fat diet+BL fermented SJH 200 mg/kg). For 8 weeks later, we examined body weight, total cholesterol, high-density lipoprotein (HDL)-cholesterol and blood glucose. Results: The control group showed significantly increased weight gain compared with normal group and SJH-LP and BL groups had less weight gain than control group, significantly. In the lipid serum tests, control group showed significantly increased total cholesterol levels compared with normal group and only SJH-LP represented decreased total cholesterol levels compared with control group. However there was no significant change in the HDL-cholesteol levels. In the blood glucose tests, that of control group significantly incereased more than that of normal group, SJH-BL showed significantly decreased blood glucose levels compared with control group. Conclusions: SJH-LP, SJH-BL showed weight control effect, SJH-LP decreased TC and SJH-BL reduced blood glucose.
