Objectives : The purpose of this study was to determine the impact of the sociodemographic and health characteristics on the out-of-pocket health spending of the individuals aged 20 and older in Korea. Methods : We used the data from the 2001 National Public Health and Nutrition Survey. The final sample size was 26,154 persons. Multiple linear regression models were used according to the age groups, that is, one model was used for those people under the age of sixty-five and the other was used for those people aged sixty-five and older. In these analyses, the expenditures were transformed to a logarithmic scale to reduce the skewness of the results. Results : Out-of-pocket health expenditures for those people under the age of 65 averaged 14,800 won per month, whereas expenditures for those people aged 65 and older averaged 27,200 won per month. In the regression analysis, the insurance type, resident area, self-reported health status, acute or chronic condition and bed-disability days were the statistically significant determinants for both age groups. Gender and age were statistically significant determinants only for the non-elderly. Conclusions : The findings from this study show that the mean out-of-pocket health expenditures varied according to the age groups and also several diverse characteristics. Thus, policymakers should consider the out-of-pocket health expenditure differential between the elderly and non-elderly persons. Improvement of the insurance coverage for the economically vulnerable subgroups that were identified in this study should be carefully considered. In addition, it is necessary to assess the impact of out-of-pocket spending on the peoples' health care utilization.

This study examined how walking moderates the influence of depression on quality of life in elderly. Data of the study were analysed using the sixth Korean National Health and Nutrition Examination Survey (KNHANES V-2, 2014). The subjects were elderly aged 65 years or more and the number of the sample was 1,263. Using hierarchial regression analysis, walking as a moderator of the depression and quality of life relationship was examined. Quality of life for elderly showed significant differences according to sex(t=8.26, p<.001), age(t=5.19, p<.001), number of chronic disease(F=37.88, p<.001), depression(t=9.62, p<.001) and walking per week (t=47.36, p<.001). Walking moderated the relationship between depression and quality of life in elderly. Based on these findings, the enhancement of walking in depressed elderly is recommended to promote the quality of life.

With change in the pattern of disease occurrence and increase in the interest in health, efforts to assess the health status on patients covering their subjective awareness at the same time as clinical and objective evaluation on health are continued. To measure health-related quality of life can be one of these efforts. This study was performed to evaluate the relevance of the quality of overall health-related-life and oral health condition. Also the second year (2014) materials in the 6th the National Health and Nutrition Survey were applied to this study. The factors affecting general health related quality of life measured by EuroQol-5 dimension (EQ-5D) have been confirmed by gender, age, education level, income level, private health insurance, perceived health status, toothache experience during the last 1 year, remaining tooth number. As oral health plays an important role in determining the overall health conditions, objective oral health state influences the whole body health. Hence, it can be regarded that oral health is ultimately related to the general health-related quality of life.

Depression is a disease with an increasing prevalence worldwide, and is highly associated with mortality as well as several diseases such as hypertension. The aim of this study is to discover clinical risk indicators associated with depression in the occupational group of simple labor workers. This study used the Seventh Korean National Health and Nutrition Examination Survey (2016-2018) conducted by the Korea Centers for Disease Control and Prevention. In association between depression and demographic information, age, sex, degree of stress perception, and stress perception ratio indices had a very high statistical association with depression, and education level and marital status were also associated with depression. Obesity indices such as abdominal circumference and body mass index were not associated with depression. Among the blood information, hemoglobin and hematocrit were highly associated with depression, and statistical significance was maintained even in the analysis adjusted for sex and age. The results of this study can be used as information for the prevention and treatment of depression in the occupational group of simple labor workers in the future.

Purpose: The aim was to explore the relationship between health status/life style and prevalence of atopic dermatitis in adolescents. Methods: Data from 1,743 adolescents (aged 13 to 18 years) derived from the fourth Korea National Health and Nutrition Examination Survey (KNHANES) were analyzed using binary logistic regression and the classification and regression tree (CART) model. Results: The prevalence rate of atopic dermatitis was 10.3%. Third quartile income class (OR=2.19, 95% CI=1.20-4.00), fair and unhealthy self-rated health (OR=1.49, 95% CI=1.06-2.11; OR= 2.73, 95% CI=1.64-4.55), past or current smoker (OR=0.41, 95% CI=0.20-0.85; OR=0.44, 95% CI=0.21-0.92), and more than average stress (OR=1.43, 95% CI=1.03-1.99) were related with increased prevalence of atopic dermatitis. The high prevalence risk groups for atopic dermatitis were adolescents who perceived themselves to be healthy on self-rated health and had more than average stress and those who perceived themselves to be unhealthy and who never smoked. Conclusion: The results of the study indicate that health status, smoking, and stress are associated with a prevalence risk for adolescent atopic dermatitis in different degrees. Therefore, for control of atopic dermatitis, various interventions for smoking and stress need to be reinforced for the high prevalence atopic dermatitis groups.

This study aimed to examine whether needs for scaling are associated with health behaviors in a representative sample of middle-aged Korean people. We examined 5120 individuals aged 40 to 64 years who participated in the Seventh Korea National Health and Nutrition Examination Survey. Multivariate logistic regression analysis was performed with adjustments for demographic variables and health status. This analysis revealed significant associations between needs for scaling and the following: current smoking, no visits to dental clinics, current drinking, non-oral checkups, and non-use of oral care products. As a result of a subgroup analysis, significant factors differed according to gender. As a result of this study, needs for scaling were associated with identified health behaviors and findings about health behaviors that are effective for maintaining and promoting periodontal health in middle-aged people were confirmed.

Objectives: The object of this study is to assess the relationship between socioeconomic factors and the predicted 10-year risk of cardiovascular disease by using health risk appraisal of ischemic heart disease. Methods: The study population was taken from The 2001 Korea National Health and Nutrition Survey, and it consisted of 1,566 men and 1,984 women aged 30-59. We calculated 10-year risk using the risk function of ischemic heart disease as developed by Jee. The educational level and equivalized household income were dichotomized by a 12 years education period and the median income level. Occupation was dichotomized into manual/non-manual work. We stratified the population by age(10 years) and sex, and then we rated the risk differences according to socioeconomic factors by performing t-tests for each strata. Results: There were gradients of the predicted 10-year risk of ischemic heart disease with the educational level and the equivalized household income, and thet was an increasing tendency of risk differences with age. Manual workers didn't show significant risk difference from non-manual workers. Conclusions: There was definite relationship between low socioeconomic position and the predicted risk of ischemic heart disease in the future.

This study aimed to find health related lifestyle factors that influence glycemic control for diabetes mellitus (DM) management strategies. This study used nested case-control design with matching variables that were not controlled by individuals such as age, sex, insulin or oral hypoglycemic agent (OHA) use, disease duration, education level and household income. This study analyzed 983 subjects with type 2 DM who enrolled in the $7^{th}$ (2016-2017) Korean National Health and Nutrition Examination Survey (KNHANES). The target HbA1c level of controlled glucose was defined as less than 6.5%, and 289 (30%) were achieved. Conditional multivariable logistic regression analysis was performed to find self-control factors associated with HbA1c levels. The results statistically significant for variables such as duration of diabetes, insulin or OHA use in overall cohort and body mass index (BMI), smoking and fundus Examination in matched cohort. These results are expected to provide as evidence for the intensive care criteria(disease duration, drug use) and lifestyle management strategy(BMI, smoking, fundus examination).
