Purpose: Investigating the prevalence of hyperuricemia and its association with metabolic syndrome (MetS) and cardiometabolic risk factors (CMRFs) in Korean children and adolescents. Methods: This cross-sectional survey used data from the 7th Korea National Health and Nutrition Examination Survey (2016-2017); 1,256 males and females aged 10-18 years were included. Hyperuricemia was defined as serum uric acid levels were >6.6 mg/dL at 10-11 years of age (both sexes), >7.7 mg/dL for males at 12-18 years of age and >5.7 mg/dL for females at 12-18 years of age. MetS was defined by the International Diabetes Federation criteria. Logistic regression analysis was used to analyze hyperuricemia-associated risk factors. Results: The prevalence of hyperuricemia was 9.4% (male, 8.4%; female, 10.5%) (P<0.281). After adjusting for sociodemographic factors and health behaviors in multivariate analysis (model 1), the odds ratio (OR) for hyperuricemia of MetS was 3.05 (95% confidence interval [CI], 1.17-7.92; P=0.022). After adjusting for the same variables in model 1 plus obesity and all MetS components (model 2), only abdominal obesity was significant, and the OR for hyperuricemia was 3.38 (95% CI, 1.72-6.63; P<0.001) After adjusting for the same variables in model 1 plus body mass index (BMI) z scores and all MetS components except abdominal obesity (model 3), only BMI z scores was significant, and the OR for hyperuricemia was 1.59 (95% CI, 1.34-1.89; P<0.001). Conclusion: MetS, abdominal obesity, and BMI z scores were CMRFs significantly associated with hyperuricemia in Korean children and adolescents. Therefore, attention should be paid to hyperuricemia in patients with obesity or MetS.

Purpose : The aim of this study was to evaluate whether breast milk feeding at infancy has the effect of a programming agent preventing school-age obesity, or whether formula milk feeding is the cause of elementary school-age obesity. Methods : We randomly selected 4 elementary school in Masan and Changwon city. We calculated the BMI and obesity degree from height and weight data on the school record of 1,275 children of first and second grade. The parents of 1,275 children were asked to a questionnaire about their birth history and feeding modality during infancy. Based on these data, we categorized them into 4- different groups : breast fed for less than 2 months; breast fed for 2-6 months; breast fed more than 6 months; mixed fed. We compared the mean BMI, obesity degree and prevalence rates of obesity of each groups. Results : There was no statistical difference on the prevalence rates of overweight and obesity, which was defined by BMI, according to the duration of breast feeding. The same was true for mild obesity and moderate obesity, which was defined by obesity degree. The mean BMIs and the mean obesity degree were not different among different feeding types. Conclusion : There seems to be no protective effect of breast feeding during infancy on reducing the prevalence rates of overweight and obesity. However, even wider and larger studies considering confounding factor might be needed to reach a definite conclusion in the future.

Purpose: The purpose of this study was to assess the difference between prevalence and risk factors of the metabolic syndrome(MS) by gender in type2 diabetic patients. Method: 108 participants(males 69, females 39) were recruited from the endocrinology outpatient department of a tertiary care hospital in an urban city. MS was defined by a third report of the national cholesterol education program (NCEP) expert panel on detection, evaluation, and treatment of high blood cholesterol in adults(Adult Treatment Panel III)(ATP III), and abdominal obesity was determined by Asia-Pacific criteria in waist circumference. Results: The prevalence of MS by definition of NCEP-ATP III and the Asia-Pacific criteria in waist circumference was 39.3% in males and 66.7% in females type2 diabetic patients. The abdominal obesity prevalence was seen in 44.9% of males and in 79.5% of females patients. The prevalence of low HDL-cholesterolemia in serum was 26.2% in male, 52.8% in female type2 diabetic patients. Conclusion: These results show that nurses should focus on female diabetic patients for preventing MS.

Objectives: The objective of this study is to investigate the relation between the obesity prevalence of elementary school students and some factors such as socio-demographic factors, parent's obesity, diet habit and physical activity. Methods: The students of the fourth(443), fifth(405) and sixth grade(417) at six elementary schools in the school district of Daejeon metropolitan city were sample-surveyed and classified into a normal group, a non-intensive obesity group, and a highly intensive obesity group. Results: 1. The obesity rate of the elementary school students in the school district of Daejeon metropolitan city was total 14.2%. 2. The obesity rate of students with parents who had high BMI was notably higher than the other groups. 3. Diet factors such as eating fast, always eating one more, liking fatty food and the frequency of snacks were more critical than physical activity factors in relation to school children's obesity. Conclusions: From the above evidences, it is apparent that the obesity of elementary school students have strong relations with eating habits. It is needed that obesity prevention program such as effective meal guidance in addition to intense physical activities is included in the curriculums of health education for elementary school students.

Purpose： The purpose of this study was to estimate obesity rate among mentally disabled children in six public schools in Korea. Furthermore, this study identified several factors that correlated with these children's obesity. The results of this study can help identify mentally disabled children who are at an increased risk for obesity and can be used to promote good health in this population. Methods： 1,102 subjectsfrom six public special schools were classified 4 groups who assessed for BMI for age-gender specific reference chart(1998) based on our previous data. Moreover, 207 parents were surveyed to identify predisposing factors for children's obesity, including characteristics of the children and parents, socioeconomic factors, children's eating habits, and children's exercise habits. Results： The prevalence of obesity among the 1,102 mentally disabled children was 17.3%. There was a statistically significant correlation between obesity and factors, such as age, maternal education, parents' perceptions about their child's obesity, frequency of breakfast, and exercise habits. Each of these factors was determined to have a statistically significant influence on obesity when all other factors were controlled in a multivariate analysis with multiple logistic regression analysis. Conclusions： Parental perceptions had an especially strong impact on the weight of their mentally disabled child. This is presumably due to the great influence that parents have on the lifestyles of their children, including dietary habits and frequency of exercise. Furthermore, the rate of obesity was directly proportional to the age of the child. The results of this study strongly indicate the need for preemptive health education programs that stress weight management for mentally disabled elementary school students.

Objective: To examine the effects of sodium intake on the correlations between the saltsensitive gene ${\alpha}$-adducin 1 (ADD1) and inflammatory cytokines in Korean childhood obesity. Methods: A total of 2,070 students aged 8-9 years old participated in this study. The anthropometrics, serum biochemistry profile, inflammatory cytokines, and three-day dietary assessment were analyzed according to sex, obesity degree, and ADD1 polymorphism. Results: The obesity prevalence was higher in boys (15.6%) than in girls (11.9%). Boys also showed higher values in anthropometrics; lipid, glucose, and insulin profiles; total calorie intakes, as well as those of sodium and calcium compared with those of the girls. The more obese were boys and girls, the higher were the anthropometrics and the blood levels (total cholesterol, triglyceride, low-density lipoprotein cholesterol, fasting blood sugar, and insulin), but the lower was high-density lipoprotein cholesterol. The obese boys had significantly higher sodium and Na/K intakes, while the obese girls had higher visfatin level and Na/K intake. In addition, an increase in the risk factors for blood pressure and obesity in ADD1 variants was identified. Serum tumor necrosis $factor-{\alpha}$($TNF-{\alpha}$) significantly increased with increasing sodium intake in the ADD1 W allele carriers, regardless of sex. The presence of obesity with the ADD1 W allele induced inflammatory accelerators such as $TNF-{\alpha}$ or C-reactive protein(CRP) with higher sodium intake. Conclusion: Obese children with an ADD1w allele can experience a more complex form of obesity than non-obese when exposed to an obesity-inducing environment and need to be controlled sodium intake in the diet.

The aim of this study was to estimate the prevalence of the metabolic syndrome risk factors for adults in the general population, understand the relationship of each factor with the obesity indicators, and examine the relevance and validity for predicting the metabolic syndrome in obese indicators. The study subjects were 1,051 adults aged 20 years and over, who underwent a health package check-up at the Korea Association of Health Promotion, D-branch from Feb. to Nov. 2014. As a result, the prevalence rates of metabolic syndrome of the study subjects were 21.5%, and the prevalence rates of the metabolic risk factors were as follows: 31.8% of men and 41.6% of women for abdominal obesity; 35.6% of men and 17.3% of women for TG; 17.6% of men and 34.2% of women for HDL-C; 53.5% of men and 35.9% of women for blood pressure; and 14.9% of men and 6.8% of women for FBS. The prevalence rates of metabolic syndrome were significantly higher in the older age group, in the group with the higher BMI, and in the group of higher level of drinking frequency. In the predictive indicators of obesity on metabolic syndrome risk factors, the waist / height ratio was higher than other indicators. Conclusively, WHtR appeared to be a useful indicator to show abdominal obesity and is better in selecting metabolic syndrome patients compared to other obesity indicators.

Purpose: The aim of the study was to assess the prevalence of preschooler obesity/overweight and to identify associated factors. Methods: This study was a cross-sectional study. Data for 591 preschoolers, 432 fathers and 538 mothers from the Korea National Health and Nutrition Examination Survey 2013-2014 were included. Obesity/overweight was defined by 2007 Korean National Growth Charts. T-test, Rao-Scott ${\chi}^2$, multivariate logistic regression was used for the analysis. Results: Prevalence rates for preschooler obesity/overweight were 14.9% (obesity, 5.4%; overweight, 9.5%). The preschoolers with atopic dermatitis or allergic rhinitis or asthma (OR=2.78, 95% CI [1.27-6.09], p=.011) and eating more thiamine per day (OR=1.01, 95% CI [1.00-1.02], p=.001) showed higher obesity/overweight development. The only parental factor affecting preschooler obesity/overweight was parental body mass index (father, OR=1.18, 95% CI [1.09-1.28], p<.001; mother, OR=1.09, 95% CI [1.04-1.15], p<.001). Conclusion: Interventions on preventing preschooler obesity should be introduced much earlier for children with risk factors. Results from this study can be used as preliminary data to develop effective strategies to prevent obesity in Korean preschoolers.

Background: This study investigated the association between obesity and cardiometabolic disease clusters in Korean adults aged 19-39 years. Methods: We included 3,785 participants (1,767 men and 2,018 women) aged 19-39 years who participated in the Korea National Health and Nutrition Examination Survey (2020-2022). The risk factors for cardiometabolic disease were defined as follows: high blood pressure; hypertriglyceridemia; hyperuricemia; and high low-density lipoprotein cholesterol, low high-density lipoprotein cholesterol, high fasting plasma glucose, elevated alanine aminotransferase levels. Results: The prevalence of participants with ≥ 1, ≥ 2, and ≥ 3 cardiometabolic disease risk factors was 95.2%, 84.2%, and 65.6% in men and 90.0%, 70.5%, and 43.0%, in women with class 2-3 obesity, respectively. Compared to those for young adults with underweight/normal weight, the odds ratios (ORs) and 95% confidence intervals (CIs) for the clustering of cardiometabolic risk factors were 17.26 (8.32-35.80) for ≥ 1; 19.43 (12.18-31.00) for ≥ 2; and 22.93 (14.15-37.15) for ≥ 3 factors in men with class 2-3 obesity and 14.67 (8.00-26.91) for ≥ 1; 20.88 (12.15-35.88) for ≥ 2; and 36.26 (20.20-65.09) for ≥ 3 factors in women with class 2-3 obesity. Conclusion: Although the patients were young, the prevalence and ORs for cardiometabolic disease risk factor clusters in young adults with obesity were prominently high. Prevention and management of obesity in young Korean adults are urgently needed at both individual and public levels.
