Purpose: The purpose of this study was to examine physical activities and health belief in order to provide basic data on obesity prevention and management among elementary school students based on the health belief model. Methods: Participants included 194 fifth grade students in an elementary school located in Seoul. Data were collected by questionnaires and physical measurement, including weight and height. The SPSS Win 17.0 program using descriptive statistics, ANOVA with Scheff$\acute{e}$ post hoc tests, and Cronbach's alpha coefficients was used in data analysis. Results: Significant differences were observed in physical activity according to perceived severity (F=3.444, p=.034), perceived benefit (F=7.674, p=.001), perceived barrier (F=21.014, p<.001), and self-efficacy (F=22.098, p<.001). A significant difference in physical activity (t=4.502, p<.001) and perceived severity (t=-2.278, p=.024) was observed according to gender. Significant differences in physical activity (t=7.633, p=.006), perceived barrier (t=10.826, p=.001), and self-efficacy (t=5.928, p=.016) were observed according to obesity status. Significant differences were observed in physical activity (F=7.503, p=.001), perceived susceptibility (F=37.904, p<.001), and perceived barrier (F=3.425, p=.035) depending on level of satisfaction with body image. Conclusions: In order to promote physical activity among children with low physical activity, development of program with an emphasis on the benefits of physical activity and physical activity self-efficacy, and to decrease the barriers to physical activity is needed.

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.

Objectives The purpose of this research is to find out the relationship between Zema 21 and in body based on the Sasang Constitutional difference of children. Methods We collected 1050 children from 5 years old to 15 years old who had been tested for both Zema21 and Inbody in OO oriental hospital from the period of September 1, January 1999 to August 31, 2008. This research investigated the Constitutional differences based on the relationship between Zema21 and Inbody. Results 1. It turned out that the children's height does not have a significant relationship between their age and gender. 2. Generally, Taeumin's weights were significantly high than those of Soyangin's and Soumin's in certain ages in children over 9 years old and in all genders. 3. The percentage of the body fat in Taeumin were significantly high than Soyangin and Soumin in certain ages in children over 10 years old and in all genders. 4. Waist-Hip ratio in Taeumin were significantly high than Soyangin and Soumin in male over 10 years old and in female over 13 years old of children. On the other hand, there was no relationship to the Soyangin and Soumin. 5. The obesity degree in Taeumin were significantly high in all female and male who were over 10 years old. Soyangin were the next highest group and Soumin follows. 6. Body Mass Index in Taeumin were significantly high in all genders who were over 10 years old. The second is Soyangin, and the lowest groupis Soumin. 7. The Basal Metabolic Rate resulted as significant in all age, although this does not have any relationship between age and gender. 8. Abdomen out in Taeumin were significantly high in ages over 10 and genders. The second is Soyangin and the lowest is Soumin. 9. Hip circumference Abdomen out in Taeumin were significantly high in ages over 10 and genders. Specially, Taeumin shows highest value, then the second is Soyangin, and the lowest is Soumin who were over 12 years old. Conclusions The results of Inbody were not significant to the children who were under 9 years old. Taeumin became significantly fat after over 10 years old. The results of Body Composition except height and Basal Metabolic Rate(MBR) were the highest in Taeumin, and Soyangin and Soumin were the second, and the third respectively.

This study was done to determine the factors associated with childhood overweight in 721 sixth grade elementary school students, in Busan. The students' heights, weights, waist circumferences and triceps-skinfold thicknesses were measured using standard techniques. Other data were collected using a questionnaire that included information about physical activity, television watching, and the amount of exorcise taken during leisure times, family history of diseases related to obesity: social data including family income, parents'education and occupations, eating behaviors; parental weights and heights; and parental activity levels. Childhood overweight was defined as a body mass index at or above the 85th percentile for age and sex. The prevalence of overweight revealed no significant difference between sexes, (24.2% in boys and 22.03% in girls). The risk of childhood overweight was significantly greater if either the mother or the father were overweight. The odds ratio for childhood overweight associated with maternal overweight was 5.045 (94% CI : 3.262-7.801), and 2.727 (95% CI : 1.764-4.218) was the case for parental overweight. Children having a history of hear diseases had higher odds ratios than those who did not. The odds ratios for overweight associated with income were not different. However, a higher odds ratio for overweight was observed in children whose fathers had only an elementary or middle school education than those whore fathers had a high school or college education. Children whose fathers' occupations were service workers or shopkeepers (OR : 3.314, 95% C = 1.851-5.934) or had no occupation (OR = 3.756, 95% CI : 1.898-7.430) had a treater risk of overweight than those whose fathers'were professionals or once workers. The risk of overweight increased in children having more irregular meal times and faster eating times, rather than those having an intake pattern of high energy and sugar containing floods. The amount of exercise taken during leisure times, and daily physical activity showed no difference between overweight and non-overweight children. However, television watching time, especially on weekends, was greater in overweight children than in non-overweight children. Television watching time was positively correlated with BMI, triceps-skin(31d thickness, waist circumference and waist/height ratio. Therefore, television watching was found to be a useful predictor of overweight in children. Television watching in children was negatively related to paternal activity levels, and positively related to parental television watching time. In fact, fathers whose children were overweight were physically less active than fathers whose children were non-overweight. Parents appeared to be a strong influence on their children's physical activity levels. In conclusion, a low family social class, defined on the basis of the father's occupation or education, parental overweight, increased television watching, and unhealthy physical activity levels in parents were all considered risk factors for childhood overweight. Among these, television watching time and lack of physical activity were considered to be the most important risk factors that could be easily modified for the prevention of and intervention in, overweight in children.

Over the period between January 1997 and December 1998, herbal medicine was more than three times administered to the patients coming to Na dong gyu's Oriental Medical Clinic on account of the symptom of growth deficiency. According to radiological opinions about the patients providing cooperation for measuring their height and weight as well as their bone age every three months, it was found that the growth plates were not closed. A research was conducted for 200 children randomly selected of patients in prepuberty (they grew by less than 5cm a year before treatment at a age of 12years for female children and 14years for male children). As a result, the following conclusion was drawn: 1. The randomly selected subjects were made up of 116 male and 84 female children in terms of gender. The age direstribution was most 10 to 12 years in 86 children(34.00%), followed by 8-10 years(27.50%) and 12 to 14 years(19.50%). 2. Considering the distribution of sick children's parental height, the fathers of 141 children(70.50%) measured less than 170cm high, the subaverage height, while the mothers of 172 children(86%) measured less than 160cm high, the subaverage height. It was shown that sick childen's height was genetically influenced by their parents. 3. Children patients's weight at a time of birth was most 3.1-3.5kg for 85 children(44%) and less than 2.5kg which came under the range of growth dificiency for 19 children(9.5%). 4. The highest proportian of the children patients with growth dificiency(56.33%) had the symptom of digestive disorders, of which 77 children patients(18.78%) had anorexia, 16.59% of children patients had the high level of respiratory disorders. Both the digestive disorder and the respiratory disorder put together, they had the high rate of 72.92%. Therefore, this indicates that both the digestive disorder and the respiratory disorder have a great effect on children's growth dificiency. 10.74% of chilren patients were shown to have allergic disorders, which indicates that they also exert an effect on growth deficiency. Specifically, 7.07% of the children patients had the high level of obesity, which shows that an excessive uptake of nutrition may rather induce children to have growth dificiency though an appropriate amount of nutritional uptake is necessary. 5. Comparing their bone age and their chronological age, 58 children patients(29.00%) showed that they were the same at the highest percent. 79 children patients(39.50%) showed that thier bone age was lower than their chronological age. And 63 children patients(31.50%) showed that their bone age was higher than their chronological age. 6. As regards the prescription administered to children patients for treating their growth dificiency, Growth tang A related to the kidney, the congenital factor, of the causes for growth dificiency in traditional Oriental Medicine was administered to 108 children patients(54%), whereas the Growth tang B related to the spleen, the acquired factor, was administered to 92 children patients(46%). 7. 116 male children patients with growth dificiency had the average value of growth for one year before treatment, 4.39cm, while 84 female children patients had the average value of growth for one year before treatment, 4.24cm. A total of 200 children had the average value of growth for one year before treatment, 4.33cm. The annual average value of growth in growth curve surveyed by the Korea Pediatrics Society was 5.79cm. Compared to this value, the one year average value of growth for 108 male and female children patients taking Growth tang A was shown be 8.44cm, which indicates a greater growth by 4.12cm(95.37%) in comparison with the average value of growth before treatment, 4.32cm, and a greater growth by 2.65cm(45.77%) compared to 5.79cm, the average value of growth in growth curve surveyed by the Korea Pediatrics Society. Also, the average value of growth before treatment for 92 male and female children patients taking Growth tang B was shown to be 8.47cm, which indicates a greater increase by 4.15cm(96.06%) compared to 4.32cm, the average value of growth before treatment and a greater increase by 2.67cm(46.29%) in comparison with 5.79cm, the average value of growth in growth curve surveyed by the Korea Pediatrics Society. Considering the average value of growth for male and female children patients taking Growth tang A and B, it was shown to be 8.46cm, which indicates a greater increase by 4.14cm(95.81%) compared to 4.32cm, the average value of growth before treatment, and a greater increase by 2.67cm(46.11%) compared to 5.79cm, the average value of growth in growth curve surveyed by the Korea Pediatrics Society.

This study was carried out to find out differences about meal conditions and food preference between non-obese and obese elementary school children. Ten children(non-obese 5 and obese 5) from each of the nationwide 192 schools were surveyed by self-developed questionnaire. Total of 1,767 questionnaires(815 from non-obese and 952 from obese children) were collected and data were analyzed using SPSS 12.0 program. The results of the comparative analysis were summarized as follows. There was not significantly different in height between non-obese $group(151.0{\pm}12.5cm)$ and obese $group(151.2{\pm}12.3cm)$. But BMI was significant difference between non-obese $group(18.0{\pm}2.2cm)$ and obese $group(27.3{\pm}3.2cm)$. Economical status was not significantly different between 2 groups. But educational level of parents and mother’ job were significant differences between 2 groups. Only 2/3 of the subjects reported to have breakfast at regular basas, regularity of having breakfast was not significantly different between 2 groups. Also regularity of having lunch during vacation was not significantly different between 2 groups. But Reasons of skipping breakfast and lunch were significantly different between 2 groups. Regularity of having dinner, reasons of skipping dinner, intake amount in dinner, and frequency of having snacks were significantly different between 2 groups. But the time required for lunch and dinner were under 20 minutes of 60-80% of the subjects, and were not significantly different between 2 groups. Non-obese group have liked fast foods, fruits & juices, sweets, and cakes & cookies than obese group. Obese group have liked meat & meat products and ramyeon, but they have not eaten those foods frequently because of anxiety about being more fatty. These findings suggested that nutrition education programs include different strategy according to obesity and obese prevention program is needed for non-obese school children.

Growth charts are curves or tables that facilitate the visualization of anthropometric parameters, and are widely used as an important indicator when evaluating the growth status of children and adolescents. The latest version of the Korean National Growth Charts released in 2007 has raised concerns regarding the inclusion of data from both breastfed and formula-fed infants, higher body mass index (BMI) values in boys, and smaller 3rd percentile values in height-for-age charts. Thus, new growth charts have been developed to improve the previous version. The 2006 World Health Organization Child Growth Standards, regarded as the standard for breastfed infants and children, were introduced for children aged 0-35 months. For children and adolescents aged 3-18 years, these new growth charts include height-for-age, weight-for-age, BMI-for-age, weight-for-height, and head circumference-for-age charts, and were developed using data obtained in 1997 and 2005. Data sets and exclusion criteria were applied differently for the development of the different growth charts. BMI-for-age charts were adjusted to decrease the 95th percentile values of BMI. Criteria for obesity were simplified and defined as a BMI of ${\geq}95th$ percentile for age and sex. The 3rd percentile values for height-for-age charts were also increased. Additional percentile lines (1st and 99th) and growth charts with standard deviation lines were introduced. 2017 Korean National Growth Charts are recommended for the evaluation of body size and growth of Korean children and adolescents for use in clinics and the public health sector in Korea.

Purpose: Obesity and headache are two highly prevalent diseases both in childhood and adolescent. In this study, we assessed the prevalence of obesity in pediatric headaches patients in a single institution in Korea, and differences according to age, sex, headache type, frequency, intensity, and disability. Methods: We retrospectively reviewed the medical records of 340 subjects (6-18 years of age) who visited the Pediatric Headache Clinic of Bucheon St. Mary's Hospital during the period from January 2015 through March 2018. Data on age, sex, height and weight, as well as headache type, frequency, intensity and disability, were collected. Body Mass Index (BMI) percentile was calculated based on the 2017 Korean Children Adolescence Growth Chart. Results: 17.6% of the pediatric headache patients were obese. The prevalence of obesity in male patients was higher than females (Male 23.8% VS Female 11.6%, P=0.002). There were no significant differences in obesity rate according to age, headache type, frequency, intensity, and disability. Conclusion: The prevalence of obesity in the pediatric headache population was 17.6% which is higher than 10.1% in general population (Korea National Health and Nutrition Examination Survey, KNHANES, 2013).

Purpose: Leptin is an adipocyte-derived blood-borne satiety factor that acts on its cognate leptin receptor in the hypothalamus, thereby regulating food intake and energy expenditure. We measured the leptin concentrations in serum of normal and obese children with human leptin ELISA kit, unlike previous study with leptin RIA kit and investigated the relationship between leptin concentrations and body mass index, gender, and age. Methods: We measured serum concentrations of leptin in 67 children who were visited to the Department of Pediatrics, Chungnam National University Hospital during the period of 5 months from February, 1999 to June, 1999. Height, weight, obesity index, and body mass index were measured in 67 subjects. Leptin values in serum were measured by sandwich ELISA method. Data analysis was done according to the obesity, body mass index, gender and age. Results: The mean concentration of leptin was $7.69{\pm}8.83\;ng/ml$ in normal children group and $36.34{\pm}18.57\;ng/ml$ in obese group. Serum leptin concentrations were significant correlation with the body mass index (p<0.01). Serum leptin concentration was significant higher in the group of over 10 years of age (p<0.01). Leptin levels showed no significant difference by gender. Conclusion: Serum leptin levels were significantly higher in obesity group than in control one, and they were correlated with body mass index and age. Measurements of leptin value by sandwich ELISA method are very useful and easily applicable to determine obesity.

Purpose: Visceral adipose tissue may be strongly linked to increased metabolic risks in adults. However, because little is known regarding the effect of visceral adipose tissue in children and adolescents, we performed this study to determine the association between abdominal fat distribution and metabolic risk factors in this population. Methods: One hundred one children and adolescents (78 males and 23 females; mean age, 10.8${\pm}$2.4 years) were enrolled. The anthropometric data and metabolic risk factors were evaluated. Theabdominal fat distribution was assessed according to the CT measurement. Age-adjusted, partial correlations were performed among the visceral adipose fat area (VFA), subcutaneous adiposefat area (SFA), metabolic risk factors, and anthropometrics. Results: The SFA increased more rapidly than the VFA with advancing years in both genders. In males, the VFA and SFA were positively correlated with anthropometrics. The VFA was correlated with low HDL-cholesterol and the SFA was correlated with diastolic blood pressure (DBP). However, there was no statistical significance between the VFA, SFA, anthropometrics, and other metabolic risk factors. The VFA and SFA were strongly linked to a number of metabolic risk factors, such as other anthropometrics. Conclusion: This study investigated how a low HDL-C was correlated with VFA and how a high DBP was associated with SFA in Korean male children and adolescents. Our results suggest that the correlation between the VFA, SFA, and metabolic risk factors was relatively weak compared to that reported in previous adult studies.
