순환표본조사를 시행할 경우 매 순환주기별로 적절한 통계적 신뢰도를 가진 전체 모집단 특성이 추정될 수 있는 반면에, 작은 표본크기로 인하여 통계적 신뢰도가 높은 소지역 추정량의 산출은 어렵다. 따라서 소지역 추정량은 일반적으로 일정 주기 후 혹은 전체조사가 마무리된 후 독립적인 순환표본들을 결합하여 얻어진 최종표본을 통해 산출된다. 본 연구에서 는 순환표본을 결합하여 추정량을 만들 때 필요한 가중치 산출의 문제를 고려하였다. 기존의 연구들이 각 조사에 따른 경험을 바탕으로 조사별로 가능한 순환표본 결합 가중치를 정의하였으나, 본 연구에서는 모든 가능한 관심변수에 적용 가능하도록 표본설계변수에만 의존하는 모형을 설정하고 주어진 모형하에서의 최량선형불편예측치(Best Linear Unbiased Predictor: BLUP)를 고려하였다. 모의실험을 통하여 각 모형 하에서 정의되는 여러 BLUP을 비교하여 모형변화에 강건한 추정량을 제안하고 그 결과를 제4기 국민건강영양조사에 적용하였다.

Measurements of health related quality of life can be used to compare patients with specific conditions to average individuals in the general population in a similar age and gender group. However there are few data available regarding health related quality of life for the general population of Korea. Therefore, this study was conducted to examine the validity of the Korean version of EQ-5D and to measure the health related quality of life of the general adult population in a metropolitan city. The survey was cross-sectional and employed a stratified and multistage sampling design through 100 examination sites in 5 districts of UIsan. A total of 12,644 individuals from 4,112 households participated in the survey. Of these, we analyzed data from 8,068 adults who were over 19 years old and completed the EQ-5D. To examine the validity of the questionnaire, the differences in 5 dimensions and the $EQ-5D_{index}$ were analyzed with regard to demographic and socioeconomic factors such as sex, age, income, and education. In addition, visual analogue scales (VAS) were used to evaluate the overall health related quality of life issues of the respondents. The level of health related quality of life of the general adult population was then compared with the results from the third Korean National Health and Nutrition Examination Survey and other countries. There were a small number of people with problems related tomobility, self-care, and usual activity. In addition, many people complained ofpain/discomfort and anxiety/depression. The complaint rate in each dimension, VAS, and $EQ-5D_{index}$ indicated relatively better states for males, the younger group, the higher income group, and the higher education group. In addition, the level of health related quality of life of the general population of Ulsan was relatively higher than that of Koreans nationwide as well as the populations of other countries. EQ-SD provided a valid measure of the health-related quality of life of the general adult population. In addition, the results of a survey of Ulsan revealed that the quality of life of its population is better than that of the overall population of Korea and of the populations of other countries.

Purpose: This study was performed to identify the socioeconomic factors, the health behavior factors and dietary pattern that have an influence on abdominal obesity, as measured by using the waist circumference in children and adolescents. Methods: This study used data collected from 1998, 2001, 2005 Korean National Health and Nutrition Examination Survey (NHANES). Final sample included 3,596 subjects from 10 to 19 years old who had completed necessary health examinations, health behaviors survey, and nutrition survey. Results: 12 dietary patterns emerged from factor analysis with different factor loading. Logistic regression analysis of the factors that affect abdominal obesity showed that the education level, BMI(Body Mass Index) and dietary pattern, 'Kimchi' including Korean cabbage and radish affected the abdominal obesity in children and adolescents. Conclusions: Abdominal obesity is a risk factor for morbidity and mortality, and it is associated with chronic diseases, including cardiovascular disease and diabetes. Based on the findings, it is essential to modify dietary pattern for preventing abdominal obesity, which is a condition associated with the incidence of chronic disease in adults.

Background: With increased interest in oral health, several efforts have been made to improve oral health conditions. To achieve this, needs for oral health must be precisely determined and accurately measured. Therefore, factors influencing both objective unmet dental needs, which were determined by experts, and perceived unmet dental needs, which were determined by patients, were examined in this study. Methods: Responses of 17,735 respondents aged greater than 19 years from the Korean National Health and Nutrition Survey collected using the fifth (2010~2012) rotation sample survey were analyzed. Based on the information collected from the survey and dental examination, we determined the associations between the independent (sex and socioeconomic level) and dependent variables using a chi-squared test. Moreover, ordinal logistic regression analyses on multiple categorical values were performed using perceived and objective dental needs as the dependent variables. Results: Generally, factors influencing both perceived and objective dental needs were similar. These included sex, household income, educational level, private insurance, and subjective oral health status. However, the high-income groups had lesser perceived and objective dental needs compared to the low-income groups. Furthermore, factors such as sex, educational level, and marital status had different influence on both needs. Conclusion: Generally, factors that affect perceived and objective dental needs were similar. To minimize unmet dental needs, factors influencing both perceived and objective dental needs should be examined for a broad dental insurance coverage, and efforts to prevent oral diseases are also required.

Purpose: The purpose of this study was to investigate the level of knowledge, health belief, and self-efficacy affecting on breast self-examination (BSE), and to identify factors influencing the practice of BSE of women in their 30's and 40's. Methods: With a correlation survey design, 194 women in their 30's and 40's were recruited at 4 culture centers in Busan via convenience sampling. Measures were included with knowledge, health belief, and self-efficacy for breast self-examination and level of BSE practice. Results: Level of knowledge, health belief and self-efficacy for BSE were greater than medium level. BSE practice had positive correlations with subscales of health belief, except barrier and self-efficacy, but no relationship with knowledge. Self-efficacy, sensitivity, and benefit among the entered variables were significant factors influencing the practice of BSE, and explanatory power of these variables was 32.8%. Conclusion: Based on this study, studies are required to compare through repeated research according to age, education, occupation, environmental characteristics. In addition, to maximize the educational effect, development of the educational program in conjunction with the local community to increase breast self-examination practice and research about the effectiveness are needed.

Objectives: This study evaluated the association between osteoarthritis (OA) and health-related quality of life (HRQoL) in elderly Korean women. Methods: We selected participants (n=2,597) aged 50 years or older from Korea National Health and Nutrition Examination Survey [KNHANES] 2005-2008. Demographic and personal characteristics, medical history of OA, and EQ-5D were extracted from the KNHANES data. Results: We found that demographic variables, including age, education level, income, and personal characteristics, were important covariates associated with the prevalence of OA and with HRQoL. In this study, OA was an important factor affecting HRQoL in women. The adjusted odds ratio for HRQoL in participants with OA was 2.92 [(95% confidence interval (CI)=2.43-3.51, p<.001)] in mobility, 2.60 (95% CI=2.17-3.10, p<.001) in pain/discomfort, 2.17 (95% CI=1.78-2.65, p<.001) in usual activities, 1.65 (95% CI=1.22-2.24, p=.001) in self care, and 1.47 (95% CI=1.22-1.77, p<.001) in anxiety/depression. After adjustment of covariates, HRQoL was significantly decreased in participants with OA. Conclusions: Our findings reveal that there is a strong association between OA and HRQoL. Preventing and controlling OA may significantly improve the quality of life for elderly Korean women.

Objective: The objective of this study is to identify the risk factors for falls among the Korean elderly population. Methods: We analyzed the data on 167 persons of 65 years of age or older who have experienced falls drawn from the Third Korea National Health and Nutrition Examination Survey. We conducted a cross-tabulation analysis and logistic regression analysis of the impact of the socio-demographic characteristics, health-related behavior, mobility, and morbidity upon the frequencies of falls. Results: Among the socio-demographic characteristics, gender(p<0.001), marital status(p<0.1), and the type of medical insurance(<0.1) were found to be statistically significant, Among the constraints on mobility, the severity of walking problems, (p<0.001) and depression(p<0.05) proved to be significant, As for variables related to health-related behavior, the level of routine physical activities (p<0.001) was found significant, Finally, rheumatism(p<0.1), osteoporosis(p<0.05), diabetes(p<0.1), urinary incontinence(p<0.01) were also significant. A logistic regression analysis of the incidence of falls revealed that urinary incontinence was the most important risk factor with an odds ratio of 2.7. Conclusion: Although a variety of factors affect the frequencies of falls in the elderly population, urinary incontinence proved to be the single most important risk factor. This finding implies that education for fall prevention is crucial for those with urinary incontinence.

Background: Cancer is a major life event that imposes huge economic and mental burdens on patients and families. In addition, the diagnosis of cancer also causes significant family discordance that can lead to marital problems such as divorce or separation. The aim of this study was to investigate the association and any related gender differences between cancer diagnosis and marital disruption among cancer survivors. Materials and Methods: We used the recent cross-sectional Korea National Health and Nutrition Examination Survey ($4^{th}$ and $5^{th}$; Years 2008-2012). The study participants were 623 married cancer survivors over the age of 19. A multivariate logistic regression analysis was conducted to estimate odds ratios. Results: After adjusting for socioeconomic status and health-related behaviors, the odds ratio of marital disruption among female cancer survivors compared with male cancer survivors was 3.94 (95%CI 1.30-11.94; p=0.02). The odds ratio of marital disruption for the below-average economic level compared with the above-average economic level was 5.64 (95%CI: 1.03-31.02; p=0.05). When compared with the non-smoking cancer survivors, the smoking cancer survivors had an OR of marital disruption equal to 2.94 (95%CI: 1.08-8.00; p=0.03). Conclusions: The findings of this study suggest that the odds of marital disruption among female cancer survivors are higher than those among their male couterparts. Medical practitioners should be sensitive to early signs of marital discord in couples affected by a cancer diagnosis. Early identification and psychosocial intervention might reduce the frequency of divorce and separation and thus improve quality of life and quality of care for cancer survivors.

Objective: A significant association between blood lead levels and hypertension has been reported in many studies. The relationship between cadmium and hypertension has been debated as well. We aimed to study the association of lead, cadmium, and both with hypertension in the Korean general population. Methods: We examined 5,967 adult men and 6,074 women who participated in the Korea National Health and Nutrition Examination Survey III-VI (2005, 2008-2013 years). Logistic regression models were used to examine the relationship between blood lead concentration and blood cadmium concentration and hypertension using logtransformed blood lead and cadmium concentrations as independent variables after covariate adjustment. Results: Adjusted for general characteristics, the odds ratio of log-lead to hypertension was 2.71 (1.82-4.03), and log-cadmium to hypertension was 2.52 (1.83-3.47). Estimates were found to be statistically significant (p<0.001). When a multiple logistic model was applied, the odds ratio of log-lead and log-cadmium for hypertension were 2.24 (1.50-3.36) and 2.24 (1.62-3.10), respectively. The standardized estimate coefficients of log-lead and logcadmium for hypertension were 4.77 and 6.65, respectively. Conclusion: We observed the association of blood lead concentration, blood cadmium concentration, and both with hypertension. This study suggests that exposure to lead and exposure to cadmium are both risk factors for hypertension.
