Purpose: By virtue of good nourishment, obese boys are increasing in Korea, which may result in prevalence of cryptopenis. As milieu of economy, culture, and society changes, increased attention to the external genitalia in children should encourage surgeon to do assertive treatment for cryptopenis. But various operative methods have been devised yet to need sophistication and revision. The author performed suprapubic lipectomy and operation according to the modification of the Johnston's principle. Methods: The patient was 5 years old, 32 kg, and 122 cm. He had no pain or tenderness. The operation was done under general anesthesia. It was done with excision of suprapubic fat, cutting of retracted dartos fascia instead of removing the fascia around penile base, and anchoring of dermis and the cutting margin of the fascia to the underlying fascia such as Buck's fascia, tunica albuginea and rectus fascia at penile base. And then circumcision was performed. Results: Postoperative complication was not observed. The clinical result of the operation was satisfactory to both surgeon and parents of the patient. Conclusion: Suprapubic lipectomy and anchoring of dermis and retracted cutting dartos fascia margin to the underlying fascia in all directions at the penile base through a single suprapubic incision provide this patient with complacency.

This study was conducted to identify differences in growth based on the obesity index in sixth grade. Heights and weights of 141 students from first to sixth grades were collected from school records. Other information was gathered by survey, and the weight length index (WLI) was calculated. Subjects were classified into three groups: underweight (n = 57, UG), normal (n = 53, NG), and obese (n = 31, OG) using the WLI. Differences in weight, height, and growth velocity were compared among the three groups from the first to sixth grades. With regard to growth, the past physical status of the three groups was maintained. More than 50% of the OG was in the overweight range when they were in the third to fifth grades. Approximately 60% of NG was in the normal weight range between the first and fifth grades. More than 70% of UG was in the underweight range when they were in the first to fifth grades (p < 0.001). Growth velocity was faster in OG than that in NG and UG (p < 0.001). The annual growth rate of children was the highest when they moved from the third to the fourth grade (p < 0.001). The results indicate that general balanced diet education should be implemented in lower grades, because physical growth formed in lower grades tended to be maintained in senior grades. It would be better to educate students about diet to prevent obesity before the fifth grade when a major change in body structure has occurred.

The prevalence of obesity is continuing to increase. Self-perceived body image among women has drawn a lot of attention in Korea due to unhealthy weight control trials. This study was conducted to determine the relationship between self-perceived body image and dietary intakes among Korean women. For the analysis, 1,747 subjects were selected after eliminating those who were likely to have recently altered their diet based on the 2010 Korea National Health and Nutrition Examination Survey (KNHANES) data. The subjects were divided into three groups: underweight, normal, and obese groups according to their perception of body image. Daily nutrient intakes, NAR (Nutrient Adequacy Ratio), and food intake frequency were assessed according to age group and body image perception. Only energy intake showed differences among the three body image perception groups across all age groups, but not statistical differences. Analysis of NAR and the order of most frequently consumed food items confirmed these findings. The ratio of underweight women that perceived their body size as normal or overweight was higher with younger age. Incorrect body image perception and unhealthy weight control behaviors can cause nutritional problems. This study confirmed that nutritional knowledge is important for healthy weight control trials. Nutritional education for healthy dieting should be emphasized among Korean women.

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.

The obesity epidemic is a worldwide problem. Factors predisposing to obesity include genetics, race, socioeconomic conditions, birth by cesarean section, and perinatal antibiotic use. High protein (HP) content in infant formulas has been identified as a potential culprit predisposing to rapid weight gain in the first few months of life and leading to later obesity. In a large multicountry study the effects of lower protein (LP) formula (1.77 and 2.2 g protein/100 kcal, before and after the 5th month, respectively) were compared to those of higher protein (2.9 and 4.4 g protein/100 kcal, respectively). Results indicated that at 24 months, the weight-for-length z score of infants in the LP formula group was 0.20 (0.06, 0.34) lower than that of the HP group and was similar to that of the breastfed reference group. The authors concluded that a HP content of infant formula is associated with higher weight in the first 2 years of life but has no effect on length. LP intake in infancy might diminish the later risk of overweight and obesity. At 6 years of age HP children had a significantly higher body mass index (by 0.51; 95% confidence interval [CI], 0.13-0.90; p=0.009) and a 2.43 (95% CI, 1.12-5.27; p=0.024) fold greater risk of becoming obese than those who received the LP. In conclusion, several factors may influence development of metabolic syndrome and obesity. Breastfeeding should always be encouraged. An overall reduction of protein intake in formula non breastfed infants seems to be an additional way to prevent obesity.

Objectives: Self perceived body image among women is drawing a lot of attention in Korea due to their unhealthy weight control behaviors. To determine the relationship between self-perceived body image and dietary behaviors among Korean women, the discrepancy between actual body size and body image perception, weight control behaviors were assessed based on age groups using the 2010 KNHANES data. Methods: A total of 1,747 subjects were selected after eliminating those of likely changing their diet recently using the 2010 KNHANES data. The subjects were divided into 3 groups, self-underweight, self-normal, and self-obese according to their perception of body image. The BMI and weight control behaviors were assessed based on age groups according to the body image perception. Results: The younger, the higher ratio of underweight, women perceived their body size as normal or overweight. Exercise and reduced food intakes were dominant among various weight control methods but unhealthy methods were dominant among self perceived overweight group. Conclusions: Incorrect body image perception and unhealthy weight control behaviors can cause nutritional problems. Nutritional education should emphasize the importance of healthy weight and proper body image perception for Korean women.

Purpose : Obesity and iron deficiency are common nutritional problems. Obese children are known to have iron deficiencies, but one presented opposite opinion in Korea. This study investigated the prevalence of obesity and iron deficiency in Incheon and the relationship between iron deficiency and obesity. Methods : Physical measurement and hematologic examinations were done a 764 healthy female students aged 14 to 15 years in May, 2005. Overweight was defined as a body mass index ${\geq}85th$ percentile. Iron deficiency was defined as serum ferritin <10 ng/mL. Iron deficiency anemia (IDA) was defined as serum Hb <12 g/dL and serum ferritin <10 ng/mL and/or transferrin saturation <16%. Results : 1) The prevalence of overweight was 24.4 percent (n=186), and that of obesity 16.5 percent (n=126). Ferritin and transferrin saturation was the lowest in the normal weight group. 2) The prevalence of iron deficiency and IDA was 18.7 percent (n=102) and 5.3 percent (n=41), respectively. 3) Iron deficiency was more common in the normal weight group compared with the overweight and underweight groups. Also, the non-obese had more iron deficiency and IDA than the obese. Conclusion : The prevalence of obesity in middle school girls could be higher in Incheon than in other regions, but there might be no difference in iron deficiency. However, iron deficiency was more prevalent in the normal weight group than in overweight group. The overweight group ate more food and gained more iron, so seemed to be less prevalent in iron deficiency than the normal weight group.

The purpose of this study was to investigate the effects of nutrition education focus on food habit, eating behaviors, dietary attitude, nutrition knowledge, and nutrients intake. The nutrition education was provided to 103 overweight and obese children in Chonbuk area. Nutrition education lessons were conducted 40 min/lesson, 12 times in year (6 times/semester). We assessed the change in knowledge using a questionnaire on food habit, eating behaviors, dietary attitude, nutrition knowledge and nutrients intake using 24 hr recall method. After the nutrition education, dietary habits were significantly improved. Especially, the answer of 'Don't eat when feel full' were significantly improved (boys (p<0.01), girls (p<0.05)). And the answer of 'Eat sugar meal frequently (chocolate, candy)' which is a dietary attitude question was significantly improved (girls (p<0.05)). There were positively changes in the dietary attitude and nutrition knowledge, but there were no significant differences after program. The results suggest that this nutrition education must be continue for positive food habit change in the long term.

Purpose: Obesity has recently emerged as a significant health problem in the pediatric population, and the prevalence of non-alcoholic fatty liver disease is increasing in tandem with a significant rise in childhood obesity. Therefore, this study was conducted to clarify the risk factors of non-alcoholic steatohepatitis in obese children. Methods: We enrolled 84 obese children who visited the pediatric obesity clinic at Yeung-Nam university hospital. The patients were divided into two groups based on their alanine aminotransferase (ALT) level (separated at 40 IU/L), and the mean of ages, total cholesterol levels, HDL-cholesterol levels, LDL-cholesterol levels, triglyceride (TG) levels, as well as the mean obesity index, and body fat percentage of the two groups were then compared. Results: When the mean of ages ($10.5{\pm}1.6$ vs. $10.7{\pm}2.0$ years), total cholesterol levels ($183.0{\pm}29.1$ vs. $183.7{\pm}31.3$ mg/dL), HDL-cholesterol levels ($53.0{\pm}10.2$ vs. $55.7{\pm}13.0$ mg/dL), LDL-cholesterol levels ($113.4{\pm}30.2$ vs. $113.0{\pm}30.0$ mg/dL), triglyceride levels ($99.4{\pm}62.9$ vs. $114.2{\pm}47.3$ mg/dL), obesity indexes ($44.7{\pm}12.2$ vs. $47.9{\pm}15.1%$), and body fat percentages ($32.7{\pm}5.0$ vs. $34.0{\pm}4.8%$) of group 1 (ALT${\leq}$40 IU/L) were compared with those of group 2 (ALT${\geq}$41 IU/L), no significant differences were observed (p>0.05). However, hypertriglyceridemia (TG${\geq}$110 mg/dL) was more frequent in group 2 than in group 1 (p=0.023). Conclusion: TG may be an important risk factor in non-alcoholic steatohepatitis and further study regarding the risk factors in non-alcoholic steatohepatitis is required.

The aim of this study was to investigate nutrition education effect in the long term and short term nutrition education intervention for childhood obesity. Seventy-seven obese children aged seven to twelve who visiting obesity clinic in a university hospital were given nutrition education therapy. Long-term as well as short-term education effect had been measured based on reducing level of Body Mass Index (BMI), Relative Body Weight (RBW) and lipid profile as well as dietary behavior. Identification of factors influencing the effect of nutrition education had been tested using multiple regression analysis as well as Main Whitney test. The result showed that nutrition education intervention had a significant impact on reducing the level of BMI, RBW and lipid profile during long term and short term period. Duration of clinic visit and total number of clinic visit were the most significant factors for the short term effect for obesity treatment. However, frequent clinic visit per month was not significant factor on short term effect. Therefore sustained participation for nutrition education by the obese individual seems more important factors than other factors especially for short term effect. Although, there was the tendency of reducing weight with longer duration and frequent clinic visit, and changing health behavior, none of the factors showed statistically significant effect on the long term effect for the obesity treatment. The results may imply that more complex factors involved for the long term treatment of childhood obesity than short term treatment.
