The Korea National Health and Nutrition Examination Survey(KNHANES) consists of Health Interview Survey, Health Behaviour Survey, Nutrition Survey, and Health Examination, and is designed to produce a broad range of descriptive health and nutritional statistics for sex and age subdomains of the population. These data can be used to measure and monitor the health and nutritional status of the population of Korea. The survey has been conducted three times from 1998. The Korea Centers for Disease Control and Prevention(KCDC) is preparing for the 4th survey which is to be conducted from 2007 through 2009. This study is to design a sample for the 4th survey. The main new feature of the sampling design is using a rolling sampling design method. Since KCDC has imposed some operational requirements, e,g., the needs of producing the annual national statistics and of year-round data collection by some regular staffs, a rolling sampling design method is introduced. This is the first time in history of applying a rolling sampling design for a national-wide large scale survey in Korea. Bringing in the rolling sampling, measurement variation due to different data collectors may be minimized.

Objectives : The aim of this study was to identify the effect of employment type on health-related quality of life. Methods : This study used data from the Sixth Korea National Health and Nutrition Examination Survey. Data were analyzed with the ${\chi}^2$ test, t-test, ANOVA and multiple regression. Results : There were significant statistical differences the health-related quality of life according to employment type. The health-related quality of life of temporary workers was lower than that of regular workers. The significant predictors of the health-related quality of life of regular workers were the subjective health status, stress, age, and education. The significant predictors of the health-related quality of life of temporary workers were the subjective health status, education, stress, sleeping time, and gender. Conclusions : These results suggest that employment type affects the health-related quality of life. The research on social policy is recommended to resolve health inequalities.

This study investigated the difference of the university students' recognition, attitude, and knowledge level of health by the health education in Daejeon and Chungnam province. First, in the survey analysis result regarding the health related recognition, the students who had attended lectures of health education were surveyed not only to have higher health related recognition than the students who did not have attended the lecture of health education, but also to appear meaningful in statistics by showing significance level p<0.05 in total score. Second, in the research regarding the health related attitude, the attendance or nonattendance of health education lecture were surveyed not to have high effect on the attitude of daily lives of the university students. Third, in the analysis of health related knowledge, the knowledge level between the students who had attended lectures of health education and who did not have attended the lecture of health education showed that the students who had attended lectures of health education got more excellent correct answer rate. In this survey result, the students who had attended lectures of health education showed higher health related recognition and knowledge than the students who had not attended lectures of health education.

Objectives This study aimed to investigate the effect of social capital, health risk behavior and health status on medical care utilization by the elderly. The data and Research method Data were obtained from the 4th wave survey of the Korea Welfare Panel Study. 4,087 household members aged 65 years and over were subject to analysis. Descriptive statistics are used to describe the basic features of the data in a study. we performed a structural equation modeling(SEM) analysis to evaluate the effect of social capital and mediating effect of health risk behavior and health status. Results Results showed that factors related to medical care utilization of the elderly were different depending on types of service (inpatient and outpatient service) except health status. Age, higher social capital, more health-risk behavior and poorer health status were associated with increased use of inpatient service. Social capital was found to have a positive direct effect on it. Also, social capital had an indirect effect on reducing use of inpatient services by improving health status. On the other hand, lower age and higher household income tended to increase use of outpatient service, while higher social capital and higher health status were inversely related. Social capital had a direct effect and an indirect effect on reducing use of outpatient service and, at that time, health status played a mediating role. Conclusions Social capital may contribute to improve health status and indirectly reduce medical care utilization of the elderly by enhancing their health status. These results provide evidence that more policy and strategy considerations should be needed for the elderly to strengthen their social capital in order to enhance their levels of health and more efficient utilization of medical care.

Purpose: This study identified socioeconomic factors affecting the health status of Korean adults. Methods: Secondary data from 12,921 adults aged 19 to 64 old in the 7th Korean National Health and Nutrition Examination Survey were used. The participants' health status was measured using the indicators that included health behaviors (smoking, high-risk drinking, strength exercise, and aerobic physical activity) and health outcomes (metabolic syndrome, and subjective health status). Results: For all health behaviors and health outcomes, gender, age, educational level, and income were common affecting factors. Regarding health behaviors, the employment status was related to smoking, high-risk drinking, strength exercise, and aerobic physical activity. The marital status was related to high-risk drinking, strength exercise, and aerobic physical activity. The household type was related to smoking. The residential area was related to smoking, high-risk drinking, and aerobic physical activity. For health outcomes, the household type was related to obesity, and subjective health status; residential area was related to obesity. Conclusion: This study presented basic data for assessing the differences in health status. The characteristics of the affecting factors to health status should be considered, depending on the health behaviors and health outcomes.

The purpose of this study was to test whether moderate alcohol consumption has any positive effect on lowering blood pressure among Koreans. Study subjects were Korean adults 20 years or older (n=5,234) who participated in the 2001 Korean National Health and Nutrition Examination Survey (KNHANES). Analysis of variance and analysis of covariance were used to construct univariate and multivariate models relating alcohol consumption to blood pressure for the analysis. After adjustment for possible covariates, drinkers (regardless of drinking level) had significantly higher systolic and diastolic blood pressure, compared with never-drinker for male subjects. Diastolic and systolic blood pressures were also significantly elevated with the drinking frequency and amount of alcohol intake among male subjects. For the female subjects, only diastolic blood pressure was significantly associated with the alcohol consumption at multivariate model. however, low level alcohol consumption did not show any sign of lowing effects on blood pressure. The result implies that moderate alcohol consumption did not have any positive effect on lowering blood pressure among Koreans for either sex.

Objectives: This study aimed to evaluate the relationship between pit and fissure sealants of the molars, and caries prevalence and experience to assess the effect of sealants on caries prevention. Methods: Data from 16,119 people were extracted from the seventh Korean national health and nutrition examination survey, which was conducted from 2016 to 2018. Demographic, socioeconomic, oral health-related behavioral, and oral examination survey data were collected as independent variables. SAS statistics for complex samples and multiple logistic regression analysis (Windows ver. 9.4) was used for the statistical analyses. Results: Caries prevalence and experience were significantly associated with age, sex, daily toothbrushing frequency, interdental cleaning, and having molar sealant. Multiple logistic regression analysis revealed a significant association between having molar sealants and the caries prevalence and experience among participants under 30 years of age after adjusting socio-economic variables and toothbrushing-related factors. Conclusions: This study confirmed the effect of molar sealants on caries prevention in Korea. Our results support that the application of molar sealants in children, adolescents, and young individuals is effective in preventing caries.

Objectives: This study aims to examine factors affecting depression of adolescents by using the data of the 17th Korean Youth Health Risk Behavior Survey(2020). Methods: The total sample was 54,848 students who are in middle or high school. In this study, sociodemographic variables, health behavior variables, and stress were input to examine the effect on depression. The data was analyzed with χ²-test and hierarchical regression by SPSS statistic program. Results: The results showed that depression was related to sociodemographic factors, health behaviors, and stress factors. In the result of hierarchical regression analysis, it was found that not only stress but also other variables had an effect on depression, which had a statistically significant effect. Conclusions: It was found that there are various causes such as environmental aspects and health behaviors that surround adolescents' depression rather than a single factor such as stress. Also, stress and depression are reciprocal rather than causal. Adolescents should be subdivided into groups such as grade, gender, or academic performance to relieve stress and depression at the same time through specific interventions.
