Purpose: The purpose of this study was to investigate the prevalence fate of obesity and to assess the relationship between obese children and their family Characteristics in 3 rural area in the Chung Cheong Nam Do province. Method: The children's height, weight and family characteristics of 327 5th and 6th grade elementary school students were obtained from the individual health records and self-recorded questionnaire surveys from June 25th to July 15, 2004. Results: The results of this study are summarized as follows: 1. The prevalence rate of obesity of 5th and 6th grade of rural elementary school students was 10.5%. 2. 20.9% of obese children had obese family members and 9.4% of obese children did not have any obese family members. The birth order, family size and family structure showed no significantly difference. 3. The obese children were more affected by their parents' concerns of body image (upper quartile of 84.1) and exercise (upper quartile 61.4%) than normal children. However, there was no significantly increase with the parents' concerns about meals. 4. There was no relationship in the obese children by PBI. 5. There was no relationship in the obese children by FACES III. Conclusion: The elevation of a parent's concern of their obese child about meal regulation should be investigated further.

Purpose: The purpose of this study is to identify the relationship between BMI, eating disorders, physical symptoms and self-esteem. Methods: The research design was a descriptive correlation study. Data collection was done by using a constructive self-report questionnaire, a total 231 elementary school girls were measured. The instrument was a constructive questionnaire that consisted 115 items. Data analysis was done by SPSS WIN 10.0 using descriptive statistics, ANOVA, Pearson correlation coefncient. Results: The score of eating disorders differed significantly by the BMI : the score was highest in the group of obesity(F=4.53, p=.023). The score of physical symptoms differed significantly by the BMI : the score was highest in the group of obesity(F=3.16, p=.045). There was positive correlation between BMI and eating disorders(r=.247, p<.01), and BMI and physical symptoms(r=.186, p<.01). And there was positive correlation between eating disorders and physical symptoms(r=.253, p<.01). Conclusions: These results indicated that elementary school girls need more education and counseling on dietary. Also, to promote their normal growth development, the systematic efforts to reestablish the social standard of the beauty should be taken.

Objectives: This study was conducted to investigate the prevalence of childhood obesity, the association between the undesirable lifestyles and socioeconomic factors, the association between childhood obesity and various risk factors, including socioeconomic factors, and the agreement between the body mass index (BMI) classification and the body fat percentage. Methods: The study subjects were all the 5th grade students from all the elementary schools in Gunpo City, Kyunggi Province, South Korea (4043 children at 22 schools). The subjects were measured for their height, weight and percent body fat etc. and they were also surveyed by questionnaire from March 18th to April 25th, 2005. To determine whether the children were within normal limits or not, standardized BMIs for each age group were used. The data was analyzed by logistic regression analysis using SAS 9.0 version. Results: The prevalence of childhood obesity prevalence was 25.1 %. Boys had a higher prevalence of obesity (27.5%) than did the girls (22.5%). Children had tendencies of having undesirable lifestyles and getting obese if they had a lower socioeconomic status. The risk factors for childhood obesity were low paternal education (OR: 1.17, 95% CI : 0.97-1.42) and non-parental caregivers (OR: 1.34, 95% CI : 0.98-1.82). Other risk factors for childhood obesity were a high birth-weight, longer TV/computer-using time, a lower fruit-eating frequency, short sleeping hours and parental obesity. The agreement rate between the BMI classification and the body fat percentage was 93.1 %. Conclusions: This study showed the children had a higher prevalence of obesity: further, not only individual lifestyles, but also socioeconomic factors could influence childhood obesity. Childhood obesity was especially more problematic for children with a low socioeconomic status.

Background: Lipid accumulation product (LAP) is associated with the presence and severity of nonalcoholic fatty liver disease (NAFLD) in adults. Purpose: Here we evaluated the ability of LAP to predict NAFLD in obese children. Methods: Eighty obese children (38 girls; age 6-18 years) were included. Anthropometric measurements and biochemical values were obtained from the patients' medical records. LAP was calculated as [waist circumference (WC) (cm) - 58]×triglycerides (mmol/L) in girls; [WC (cm) - 65]×triglycerides (mmol/L) in boys. The minLAP and adjLAP were described (3% and 50% of WC values, respectively) and the total/high-density lipoprotein cholesterol index (TC/HDL-C) was calculated. NAFLD was observed on ultrasound, and patients were divided into 3 groups by steatosis grade (normal, grade 0; mild, grade 1; moderate-severe, grade 2-3). The area under the curve (AUC) and appropriate index cutoff points were calculated by receiver operator characteristic analysis. Results: LAP was positively correlated with puberty stage (rho=0.409; P<0.001), fasting insulin (rho= 0.507; P<0.001), homeostasis model assessment of insulin resistance (rho=0.470; P<0.001), uric acid (rho=0.522; P<0.001), and TC/HDL-C (rho=0.494; P<0.001) and negatively correlated with HDL-C (rho=-3.833; P<0.001). LAP values could be used to diagnose hepatosteatosis (AUC=0.698; P=0.002). The LAP, adjLAP, and minLAP cutoff values were 42.7 (P=0.002), 40.05 (P=0.003), and 53.47 (P= 0.08), respectively. For LAP, the differences between the normal and mild groups (P=0.035) and the normal and moderate-severe groups were statistically significant (P=0.037), whereas the difference between the mild and moderate-severe groups was not (P>0.005). There was a statistically significant difference between the normal and mild groups for adjLAP (P=0.043) but not between the other groups (P>0.005). There was no significant intergroup difference in minLAP (P>0.005). Conclusion: LAP is a powerful and easy tool to predict NAFLD in childhood. If LAP is ≥42.7, NAFLD should be suspected. This is the first study to assess LAP diagnostic accuracy for childhood obesity.

This study was undertaken with 542 fifth-grade elementary school children to investigate the characteristics in lifestyle, eating habits, food preferences of overweight and obese children in the Pocheon area of Korea. Anthropometry was conducted to determine obesity, and data was obtained on lifestyle, eating habits and food preferences by using questionnaires. The prevalence rate of obesity was 19.5% for boys and 8.5% for girls, and 14.3% of boys and 14.4% of girls were overweight. No significant differences was found in the body size and education years of parents, family income and the empolymental status of mother. Boys did not show any significant difference between subgroups in lifestyle, eating habits and food preferences. Obese girls watched TV longer and liked physical education less than normal and overweight groups, suggesting that an inactive lifestyle can be related to girls' obesity in this study. Overweight girls answered that they had significantly lower preferences for empty-calorie foods such as candies/caramels and cookies as well as high-fat foods such as samgyupsal(pork belly) than normal weight girls, implicating the fear of obesity for overweight girls, although more studies should be done including an assessment of actual intake of these foods. The preferences of obese girls for these foods were not higher than those of normal-weight girls, suggesting that the preference for certain foods may not be the characteristic of obese girls in this study. A special program for nutritional education with a different focus should be developed to combat the problems of each subgroup depending on gender and obesity status to improve the physical fitness of the children in this area.

Objectives To study on the relation between Sasang constitution and obesity and that of obese patient's clinical symptom. Methods The subjects were 129 female patients to visit to diet. The subjects were 129 female patients to diet who answered questionnaire QSCC II and were diagnosed by the Sasang constitution from May to December in 2001 at Nara oriental medical clinic. Results 1. Of obese patients 79.1% were Taeumin, 11.6% Soeumin, and 9.3% Soyangin. 2. A relation of a grade of obesity and Sasang constitution. 2-1) 45.8% of the obese patients were high level obesity who had over 35% of body fat. Out of these people, 91.5% were Taeumin. 2-2) 40.3% of the obese patients weight hip ratio was between 0.84 to 0.89 and 84.6% of these people were proved to be Taeumin. 2-3) 39.2% of the people who had a minimum weight hip ratio of 0.90 were significantly Taeumin, 6.7% Soeumin and 16.6% Soyangin. 2-4) 65.7% of Taeumin were obese patients. 3. Obesity treatment with constitution. 3-1) 59.8% of Taeumin were Pyo-zng patients. 3-2) As treatment periods tended to increase, Taeumin and Soeumin patients showed a large decling of body fat, whereas Soeumin patients showed the opposite reaction. 3-3) The weight hip ratio was led by Taeumin with 0.03 and then came Soeumin and Soyangin with a 0.02 ratio. As treatment was taken into process longer Taeumin patients showed a great progress in decreasing their weight hip ratios. 4. Costitutional related symptom with Obesity. 4-1) Taeumin was followed by Soyangin and then Soeumin in family history. 4-2) Soeumin was followed by Taeumin, then Soyangin when complain of physical fatigue was taken into consideration. 4-3) The ordinary exercise was led by Soyangin, Taeumin then Soeumin. 4-4) People who receive stress turned out to be 72.9% much higher than the people who don't. 4-5) Overeating due to stress was found in 83.3% of Soyangin.

Objectives The relationships between adolescent depression and obesity, life style has been reported, but usually study results were not consistent with the study before. This study was designed to evaluate clear relationship between obesity and depressive trends, life styles in middle school students. Methods The study participants were the 1th, 2th grade students from one middle school in Kang dong Gu, Seoul(479 Students). The participants were measured their height and weight, and they were also surveyed by questionnaire. We diagnosed the students as depressives when they scored 10 points or above on Children's Depression Inventory(CDI) of Kovacs and Beck. Results The mean depression score in the obese group was significantly higher than that of the normal body weight group, and the more severely obese the group was, the higher the depression scores for this group were. The depression score of the boys obese group was higher than the girls obese group. The depression score was significantly higher in the obese group of people who hate to do exercising, like computer games and like watching TV instead, than in the group of people who like to do exercising and don't play computer games. Conclusions This study showed that depressive mood during adolescent was related to obesity and obesity-related lifestyles.

Obesity is characterized as an accumulation of adipose tissue mass represented by chronic, low-grade inflammation. Obesity-derived inflammation involves chemokines as important regulators contributing to the pathophysiology of obesity-related diseases such as cardiovascular disease, diabetes and some cancers. The obesity-driven chemokine network is poorly understood. Here, we identified the profiles of chemokine signature between human preadipocytes and adipocytes, using PCR arrays and qRT-PCR. Both preadipocytes and adipocytes showed absent or low levels in chemokine receptors in spite of some changes. On the other hand, the chemokine levels of CCL2, CCL7-8, CCL11, CXCL1-3, CXCL6 and CXCL10-11 were dominantly expressed in preadipocytes compared to adipocytes. Interestingly, CXCL14 was the most dominant chemokine expressed in adipocytes compared to preadipocytes. Moreover, there is significantly higher protein level of CXCL14 in conditioned media from adipocytes. In addition, we analyzed the data of the chemokine signatures in adipocytes obtained from healthy lean and obese postmenopausal women based on Gene Expression Omnibus (GEO) dataset. Adipocytes from obese individuals had significantly higher levels in chemokine signature as follows: CCL2, CCL13, CCL18-19, CCL23, CCL26, CXCL1, CXCL3 and CXCL14, as compared to those from lean ones. Also, among the chemokine networks, CXCL14 appeared to be the highest levels in adipocytes from both lean and obese women. Taken together, these results identify CXCL14 as an important chemokine induced during adipogenesis, requiring further research elucidating its potential therapeutic benefits in obesity.

This study examined the proper roles of dietitian and nurse-teacher in the weight control program (WCP) in schools and the effect of the WCP on subjects with respect to anthropometric measurements, nutrition knowledge, dietary attiude, and behavior changes. The program consisted of six sessions of nutrition education and frequent face-to-face nutrition counseling. Subjects were 22 obese children in the 4th and 5th grade who underwent counseling and 18 obese children in another school who served as a control group. After two months of WCP, obesity index such as .elative body weight (RBW, from 135.7 to 132.5), tricep skinfold thickness (TSFT, from 34.9 to 32.8 mm), and body fat content (from 32.0 to 29.8%) had decreased significantly in the experimental group, while the control group showed no significant differences in these indices. The reductions in obesity indices were maintained in the experimental group except for fat content (32.6%), which returned to its original value within six months. The control group significantly increased fat content in the same period (from 31.2% to 36.2%). Both groups decreased RBW, TSFT, and fat content while midarm circumference and waist/hip ratio remained the same after one year. Subjects' nutrition knowledge was improved with average test scores from 15.1 to 16.7 while nutrition attitude and behavior test scores remained unchanged suggesting that behavior modification may require more time than knowledge acquirement. These results suggest that proper nutrition counseling can initiate weight reduction. However, the maintenance of controlled weight requires changes in attitude and behavior which have not been achieved by the present WCP. The role of school dietitian for WCP in this study was limited to assisting the nurse-teacher in nutrition education. Expansion of dietitian's role in nutrition education and counseling is needed.

Purpose: The rising prevalence of childhood obesity in the past decades has caused non-alcoholic fatty liver disease (NAFLD) to become the most common cause of pediatric chronic liver disease worldwide. This study was aimed at determining the effect of vitamin D (Vit D) on ultrasonography and laboratory indices of NAFLD and some blood biochemical indicators in children. Methods: In this interventional study liver ultrasonography was performed in 200 children with overweight and obesity. A 108 had fatty liver among which 101 were randomly divided into two groups of study (n=51) and control (n=50). The study group was treated with Vit D, 50000 U once a week whereas the control group received placebo with the same dose and package, both for 12 weeks. At the end of the intervention lab tests and ultrasound study was performed once again to evaluate the response to treatment. Results: It was found out that Vit D supplementation improved the fatty liver grade in the study group. The mean changes in hemoglobin (Hb), uric acid, highdensity lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), insulin, albumin and alanine aminotransferase (ALT) was significantly higher in the study group compared to controls (p<0.05). After the intervention and means adjustment, a significant difference was obtained in HDL-C, insulin, LDL-C and homeostasis model assessment of insulin resistance (HOMA-IR) between the two groups. Conclusion: Vit D supplementation in addition to improving the fatty liver grade in ultrasonography and increasing the blood Vit D level, increases the HDL and Hb level besides decreasing uric acid, LDL, HOMA-IR, insulin and ALT levels.
