The purpose of this study was to investigate the relationship among nutritional status of copper and zinc, serum leptin, and lipids of 99 middle school girls residing in kyunggi-do, Korea. Subjects were divided assigned to one of two groups such as normal (BMI<85 percentile, n=58) and obese (85$\leq$BMI, n=41) groups. Subjects were evaluated based on anthropometric measurements, 24-hr dietary recalls and blood analysis. The mean age was 13.93 years. The mean weight (p<0.001), BMI (p<0.001), body fat (p<0.001) of obese were significantly higher then those of normal group. The mean daily energy intake was 94.2% of RDA for Korean. The ratio of energy coming from carbohydrate, fat and protein was 63:24:13. The mean daily intakes of Cu and Zn were 1.4 mg and 7.4 mg (73.7% of RDA), and there were no significant difference between two groups. The mean serum levels of leptin (p<0.001), LDL-cholesterol (p<0.05), triglyceride (p<0.01), TPH (total cholesterol/HDL; p<0.001), LPH (LDL/HDL; p<0.001) and AI (atherogenic index; p<0.001) of obese were significantly higher than those of normal group. The mean serum Cu level of obese was significantly higher than normal group but, the mean serum Zn level of obese was significantly lower than normal group. Serum Cu showed a significantly positive correlations with body weight (p<0.001), BMI (p<0.001), body fat (p<0.001), serum leptin, and LPH. However, serum Zn showed a significantly negative correlations with body weight (p<0.001), BMI (p<0.001), serum leptin (p<0.001), TPH (p<0.05), and AI (Atherogenic index; p<0.05). To summarize the results, the Zn intakes of middle school girls did not reach to RDA for Koreans. Also, increase of BMI may lead to decrease of serum zinc level and increase of serum copper level, and this change of serum zinc related to the change of serum leptin and serum lipids level in middle school girls during rapid growth.

Purpose: Obese children may often present with advanced bone age. We aimed to evaluate the correlation between factors associated with childhood obesity and advanced bone age. Methods: We enrolled 232 overweight or obese children. Anthropometric and laboratory data, and the degree of nonalcoholic fatty liver disease (NAFLD) were measured. We analyzed factors associated with advanced bone age by measuring the differences between bone and chronological ages. Results: The normal and advanced bone age groups were comprised of 183 (78.9%) and 49 (21.1%) children, respectively. The prevalence of advanced bone age significantly increased as the percentiles of height, weight, waist circumference, and body mass index (BMI) increased. BMI z-score was higher in the advanced bone age group than in the normal bone age group (2.43±0.52 vs. 2.10±0.46; p<0.001). The levels of insulin (27.80±26.13 μU/mL vs. 18.65±12.33 μU/mL; p=0.034) and homeostatic model assessment-insulin resistance (6.56±6.18 vs. 4.43±2.93; p=0.037) were significantly higher, while high density lipoprotein-cholesterol levels were lower (43.88±9.98 mg/dL vs. 48.95±10.50 mg/dL; p=0.005) in the advanced bone age group compared to those in the normal bone age group, respectively. The prevalence of advanced bone age was higher in obese children with metabolic syndrome than in those without (28.2% vs. 14.7%; p=0.016). The prevalence of advanced bone age was higher in obese children with a more severe degree of NAFLD. Conclusion: Advanced bone age is associated with a severe degree of obesity and its complications.

This study investigated the health and nutritional characteristics according to household income level and obesity in Koreans aged over 50 years based on the 2005 National Health and Nutrition Examination Survey. Subjects were classified into 3 groups by average household income with reference to the minimum monthly living expenses (MLE): low (n = 319, < 100% MLE), middle (n = 222, < 200% MLE), high (n = 411, ${\geq}$ 200% MLE) and each group was compared by BMI index. With increasing income level, the prevalence of systolic hypertension and hyperlipidemia was increased. In the low income group, serum total cholesterol, triglycerides, and fasting glucose were higher in the obese compared with the normal. In the middle and high income groups, the prevalence of hyperlipidemia and diastolic hypertension were higher in the obese. Subjects had nutritional imbalance, such as inadequate intake of calcium and potassium. With increasing income level, the percentages of protein and fat to total calorie were increased in addition to the intakes and density of nutrients. The obese in the low income group had higher intakes of energy, protein, phosphorus and higher consumption frequency of cereals and potatoes compared with the normal. It was shown that the obese of the middle and high income groups tended to have lower consumption frequency of Korean cabbage and higher frequency of fruits. The obese of high income group also had binge drinking habit. Therefore, this study suggests that specific approaches based on economic status should be considered in developing nutrition education program for the elderly.

Background: Obesity and dental caries have common risk factors such as food intake, eating habits, and lifestyle. Nevertheless, there has been no consensus on the significant association between obesity and dental caries, and additional studies are needed. We investigated the relationship between obesity and dental caries in some college students in this pilot study. Methods: Forty-two obese college students (body mass index [BMI]≥25) registered at a University Obesity Clinic and 19 normal students (18.5≤BMI<25) were recruited. Oral examinations were conducted, and anthropometric data and blood samples were collected. The blood concentrations of low-density lipoprotein (LDL), high-density lipoprotein, and triglyceride were also measured. After controlling for dental plaque index, a univariate analysis of dental caries indicators related to obesity was performed; partial correlation analysis was also conducted. A nonparametric test was used for the analysis of gender-related trends due to the limited number of participants. Results: The obese group had significantly fewer missing teeth (p=0.014), missing surfaces (p=0.035), filled surfaces (p=0.038), and decayed-missing-filled surfaces (p=0.020) than the normal group. There was no difference between the males in the normal and obese groups. The females in the obese group had significantly fewer missing teeth (p=0.003), missing surfaces (p=0.003), and decayed-missing-filled surfaces (p=0.046). Partial correlation analysis showed a weak negative correlation (r=-0.256) between the blood LDL concentration and decayed-missing-filled teeth. The other obesity and dental caries indicators were not correlated. Conclusion:The blood cholesterol concentration had a negative relationship with dental caries, and there were fewer cases of dental caries in the obese group in this study. However, it is important to clarify the relationship between obesity and dental caries through a dietary survey or additional investigations considering other confounding factors.

This study was conducted to investigate the relation of adaptability to the temperature and wearing behavior in both obese and normal weight children and their mothers' guidance. A questionnaire was used and the subjects were elementary school children in the 4th to the 6th grade (1,501) and their mothers (1,459) living in Seoul, Busan, Daegu, Gwangju, and Andong cities. The children were divided into two groups: a normal weight group (NWG, 1,192) and an obese group (OG, 309). There was no relation between children's adaptability to temperature and their mothers'. OG's mothers were more affirmative than NWG's mothers in purchasing children's clothing which suited them. The more NWG's mothers purchased children's clothing which suited them, the more NWG chose clothes that were conscious of body figure, while OG's mothers chose children's clothing which suited them regardless of OG's consideration of the body figure. It is suggested that an educational program of wearing behavior of obese children and their mothers as well as various measurements for the questionnaire should be developed for more intensive studies in this field.

Purpose: This study investigated the effect of microwave diathermy against the body composition of obese women with protein content, muscle quantity, and the change of body weight for three weeks by microwave diathermy. Methods: we performed the change of body weight for three weeks using the method of 100,000 Hz microwave diathermy against obese women. The obese women were examined the change of body weight by pre-test using microwave diathermy. Results: The effect of microwave diathermy in protein content, muscle quantity, and body weight did not show any statistically significant in an experimental group of eight female university students for three weeks, but the change of body weight was statistically significant (p>0.05) for three weeks to eight students who were examined by microwave diathermy. The control group did not show any statistically significant in protein content, muscle quantity, body fat, and the change of body weight for three weeks.s). Conclusion: These results suggest that microwave diathermy may be an effective method for the management of the body and the diet in obese women.

This study was performed to investigate the eating habit, body image, and weight control behavior by BMI in Korean female high school students. Data on the 16,574 subjects was obtained from the sixth Korea Youth Risk Behavior Web-based Survey (2010). Only 52.2% of the subjects had regular breakfast. The rate of skipping breakfast was higher in the underweight group than in the obese group, but the rate of skipping dinner was on the contrary to this. Underweight students had a higher intake frequency of fruits, fast food, instant noodle, and snacks than the obese groups. 3.5% of underweight students considered themselves to be overweight or obese. 53.4% of obese students considered themselves to be overweight. The experience of weight control increased according to BMI, but underweight students considered weight control as an effort to be slimmer. Meal restriction was used more frequently to control weight. The perceived stress level was higher in obese student, especially due to appearance. Therefore, an appropriate, integrated and personalized high school nutrition program should be established for proper body image perception and to develop the self-esteem of female high school students.

This study was conducted to find associations of stress with obesity in female college students in Gwangju. 343 subjects were divided into two groups based on BMI(body mass index). BMI of normal group was $19.3{\pm}1.5$ while that of obese group was $26.4{\pm}3.6$. The measured stress level in obese subjects was higher and they were less capable of controlling obese oriented attitude compared to normal subject. Twenty four hour dietary recall revealed that nutrient intakes of obese subjects were higher in energy, lipid, P and cholesterol. However, they were more deficient in Ca, Fe and vitamin A, compared to those of normal ones. This study suggested severe stress might trigger undesirable dietary behavior leading to increase in food consumption which contribute to obesity. Effective nutrition education program targeting obese female students should be developed and implemented to relieve stress and practice desirable dietary behavior and eating pattern.

Purpose: The purpose of this study was to compare variables related to weight control between normal weight and overweight/obese female adolescents. Methods: This study is a supplementary analysis using a total of 293 female adolescents in Seoul. Data were collected through self-report questionnaires on the topics of stages of change, processes of change, and the decisional balance pertaining to weight control. Body weight and height were also measured. Results: There was a significant difference in the stages of change between the normal weight and overweight/obese groups. Of 12 processes of change, 9 processes were significantly higher in the overweight/obese group than in the normal weight groups. Also, female adolescents who were overweight or obese had significantly higher pros and eating efficacy scores comparing to those in the normal weight group. Conclusion: The findings of this study suggest that overweight/obese female adolescents, especially those in the action stage need supports to continue their weight control behaviors. In addition, a weight control program for female adolescents should emphasize their participation in physical activities in addition to their dietary control efforts.
