Objectives: The Korea National Health and Nutrition Examination Survey (KNHANES) is a national surveillance system that has been assessing the health and nutritional status of Koreans since 1998. Based on the National Health Promotion Act, the surveys have been conducted by the Korea Centers for Disease Control and Prevention (KCDC). Methods: An oral examination as part of The National Health and Nutrition Examination was proposed to calculate the sample design and survey participation. The surveying system was presented by classifying the measurement environment, screening, and survey items by year, and the merits and limitations of using the data were suggested by examining the status of survey quality management and the process of disclosing raw data. Results: This nationally representative cross-sectional survey samples approximately 10,000 individuals each year and collects information on oral examinations and oral health interviews. Data for the oral health component of KNHANES was obtained to assess the oral health status of Koreans and determine the prevalence of dental caries and periodontitis. The oral health data quality control of KNHANES was composed of three parts: "Education Program" and "Field Training Program" for quality control of oral health examiners (dentists) by the professional academy, and "Data management" by the KCDC. After completion of the three-step data check, the indicators of dental caries, periodontal disease, and oral health behavior were published in the National Health Statistics. Conclusions: To achieve the goals of oral health indicators, we will continue to monitor so that we can use it as basic data for oral policies and carry out various linkage analyses related to oral diseases.

Objectives: The study aimed to investigate the relationship between depression and number of present teeth in Korean elderly individuals. Methods: Data for this cross-sectional survey was obtained from the records of the sixth Korea National Health and Nutrition Examination Survey (KNHANES). The subjects were 1,199 Korean elderly individuals above 65 years of age. The survey and examination data were used for the independent variables. The KNHANES included health status, nutrition survey, and oral examination. $x^2-test$ was performed to identify the characteristics of depression and number of teeth present according to the characteristics of the study subjects. Logistic regression analysis was also performed to identify the relationship between depression and number of teeth present. The statistical significance level wa sset at 0.05. Results: The prevalence of depression in the subjects was 14.8%. There were statistically significant differences in the prevalence of depression, depending on gender (p<0.001), education level (p=0.001), income (p=0.001), spouse status (p<0.001), and alcohol consumption (p=0.020). The association between depression and the number of teeth present showed statistically significant difference after adjustment (p=0.040). Conclusions: Depression in elderly individuals was closely related to the number of teeth present. Therefore, public health policies for improving oral health should be established to prevent depression.

This study aimed to introduce what Korea national oral health surveys are and examine recent oral health status in Korean children. Korea Government has implemented national oral health-related surveys during the past two decades. The surveys with oral health examination are Korean Children's National Oral Health Survey (KCNOHS) since 2000 in 5-year-old and 12-year-old children and Korea National Hhealth and Nutrition Examination Survey (KNHANES) since 2007 aged 1 year and more. KCNOHS provides the information about the distribution of prevalence of dental caries, gingival health, behavioral factors, and dental clinic demands etc. KNHANES has huge amount of health data for representative Korean population including oral health and general conditions. Based on KCNOHS, the prevalence of dental caries and its experience has decreased steadily, and the status of oral hygiene and preventive treatment called sealents has been also improved after the year of 2000. However, there is still a gap to reach to those of Western developed countries. Therefore, more effective oral health policy plans and strategies for Korean children and adolescents are needed to prevent and manage for dental caries in private and clinical field of dentistry with public sector.

The purpose of this study was to investigate the prevalence and differences of risk factors of Metabolic syndrome according to menopausal status. From the database of the 5th Korea National Health and Nutrition Examination Survey (KNHANES V) conducted in 2012, data of 3,537 women who responded to health interview and health examination questionnaires. The presence of Metabolic syndrome was assessed using the International Diabetes Federation (IDF) criteria. The prevalence of Metabolic syndrome was 17.3% in premenopause and 54.3% in postmenopause. BMI, waist circumference, blood pressure, total cholesterol, LDL cholesterol, triglyceride, and Ferritin were higher in postmenopausal women compared to premenopausal women. However, postmenopausal women had lower HDL cholesterol and TIBC when compared to premenopausal women. Hypertension was the most prominent characteristic of postmenopausal women. Low HDL cholesterol showed up as a meaningful factor in premenopausal women. According to multiple regression analysis, waist circumference, fasting glucose, and HDL cholesterol were independent predictors of menopause. Therefore, obesity control and blood lipids management is recommended for postmenopausal women.

Freshwater fish intake is a critical parameter for deriving water quality criteria and water quality standards for protection of human health based on human health risk assessment. Although the freshwater fish intake parameter should be accurate and representative of Korean fish consumption for the water quality criteria to be reliable, data are limited in Korea and have low reliability. In this study, Korean National Health and Nutrition Examination Survey data from 2008-2010 were analyzed to reevaluate freshwater fish consumption. Based on these results, an average consumption rate of 3.0 g/day per person, a $90^{th}$ percentile consumption rate of 0.0 g/day per person, an average consumption rate of 65.7 g/day per fish consumer, and a $90^{th}$ percentile consumption rate of 153.4 g/day per fish consumer were proposed for derivation of water quality criteria using a conservative approach and various exposure scenarios.
