Objectives: This study was performed to investigate the associations of food security with socio-demographic characteristics, nutrient intakes and mental health status among older Korean adults. Methods: This study was conducted using data from the 2008-2010 Korea National Health and Nutrition Examination Survey (KNHANES). Subjects were 4,451 adults aged 65~98 years. Food security was measured using a self-reported question on food sufficiency of subjects' household. Based on the answers, study subjects were classified into secure, mildly insecure, moderately insecure, and severely insecure groups. Dietary intake was estimated by 24-hour dietary recall. Nutrient intake was assessed by dietary reference intakes (DRI). As for mental health status, the data on mental stress, depression, and suicide ideation were used. Results: Rate of food insecurity in older adults was 14.3%. Old age, being female, low education, low income level, living alone, and discomfort in daily living were more related to food insecurity. Means of nutrient intakes were significantly different according to food security status. Intakes of calcium, potassium, and vitamin $B_2$ were lower than recommended intakes in all groups. Consumption amounts of soy and soybean products, vegetables, mushrooms, fruits, vegetable oils, meats, eggs, seafood, and dairy products were lower in food insecure groups. Mental stress, depression, and suicide ideation were higher in food insecure groups independent of the gender and income level. Conclusions: These present findings suggested that food security is related to mental health as well as nutrition status in older Korean adults. A national system that include food and psychosocial support programs for the elderly should be considered in order to improve the overall health of older Korean adults.

Background: Edentulism is associated with socioeconomic status, rural residence, and chronic disease, but no studies have investigated edentulism and residence factors together. All information that drives a better understanding of the factors related to edentulism plays an important role in the planning and delivery of appropriate dental services for the elderly by national and oral health professionals. This study was designed to investigate the prevalence of edentulism in adults aged over 60 years in Korea and to examine whether there are differences in dentate status between people living in urban and rural areas after controlling for sociodemographic and other related factors. Methods: The data for this study were collected from 2013 to 2015 as part of the Korea National Health and Nutrition Examination Survey VI, those individuals aged over 60 years and who had complete datasets were included (5,071). The number of teeth and residence status were categorized into two groups: edentate and dentate (1 or more); urban and rural. Multiple multivariate logistic regression analyses were sequentially applied to assess the association between dentate status and residence status after adjusting for potential confounders. Results: Rural areas, lower household income, and lower education levels were associated with a higher edentate rate. The number of teeth was lower in rural areas than in urban areas. After adjusting for various factors, statistically significant associations were present for women, low household income, low education level, poor perceived health status, and alcohol consumption in participants. Conclusion: Elders living in rural areas had poorer oral health than elders living in urban areas. The government will need to provide effective systems for promoting oral health for elders living in rural areas.

Objective: This study evaluated the health behavior level of urological cancer survivors after surgery. Understand the experience of change and identify the factors that affect it for health. Selection of the best intervention steps and effective intervention adopt a lifestyle. It is intended to contribute to the creation of basic data for development of guidelines. Methods: The study was conducted with patients diagnosed with urological cancer at a hospital in Seoul. Study data were obtained by having 100 patients who agreed to the study self-fill out a questionnaire through interviews, and the 2018 World Cancer Research Fund and American Institute for Cancer Research Score (2018 WCRF/AICR SCORE) was used to estimate the level of health behavior. Results: The study examines health behavior among urolgical cancer survivors based on the 2018 WCRF/AICR SCORE. Higher household income and younger age were associated with better health behavior scores, with those under 60 and earning over 3 million won being more likely to have higher scores. Conclusion: Based on these results, this study requires comprehensive data collection considering the missing variables, suggesting that high household income and young age can positively affect healthy behavior. In addition, we conclude that education for cancer survivors and development of strategies to bridge the health gap for low-income and elderly populations are necessary.

이 연구는 65세 이상 노인의 배우자 유무를 통해서 유배우자 집단과 무배우자 집단의 인구사회학적특성, 건강행태 및 주관적 건강수준, 질병이환, 건강관련 삶의 제한 및 건강관련 삶의 질에 대한 포괄적인 평가를 해 보고자 하였다. 평가를 위해 2014년도부터 2016년도까지 3년간의 지역사회건강조사 자료를 분석하였다. 무배우자 집단이 유배우자 집단보다 여성의 비율이 높고, 가구 총 소득이 낮으며 건강행태가 불량하고 만성질환의 이환률이 높아 주관적인 건강수준도 더 낮게 나타났다. 이러한 특성으로 인해 무배우자 집단이 유배우자 집단보다 삶의 질이 낮은 것으로 분석이 되었다. 지금까지 우리의 인식은 노인을 연령기준으로 하나의 집단으로 바라보면서 그들의 평균적인 특성만을 파악하여, 그들이 가진 여러 가지 상황 문제를 간과하는 결과를 초래하고 있었다. 본 연구의 결과를 통해 배우자유무에 따라서도 노인들의 신체적 정서적 사회적 문제에 포괄적인 조치가 필요함을 알 수 있었다. 또한 개별적인 노인지지프로그램 개발을 위한 보건학적 접근과 더불어 사회 복지적 측면의 개선이 필요한 것으로 나타났다.

Objectives: The purpose of this study was to investigate the blood biochemical characteristics, comorbidities, dietary intake, and other risk factors leading to poor glycated hemoglobin (HbA1c) control in elderly Korean diabetes patients over 65 years of age. Methods: Data from the 4^th (2007-2009) and the 7^th (2016-2018) Korea National Health and Nutrition Examination Surveys (KNHANES) were used. Socio-demographic characteristics (age, gender, region, household income, education level, marital status, nutrition education, diabetes duration and diabetes treatment), lifestyle characteristics (drinking, smoking, regular walking, and subjective health perception), anthropometric characteristics (height, weight, and waist circumference), blood biochemical characteristics (HbA1c, high- density lipoprotein cholesterol, triglycerides, total cholesterol, blood urea nitrogen, and blood creatinine), co-morbidities (obesity, hypertension, hypercholesterolemia, hypertriglyceridemia, and anemia), energy and nutrients intake, food group intake, and HbA1c control-related risk factors were compared. Results: Compared to the 4^th survey, the 7^th survey showed an increase in diabetes prevalence among men, an increase in the prevalence of diabetes in the older patients, and an increase in the duration of diabetes. The energy ratio from carbohydrate consumption in the 7^th survey was lower than in the 4^th. Compared to the 4^th survey, thiamine and riboflavin intake had improved, and the intakes of vitamin A, vitamin C, and niacin had worsened in the 7^th. A comparison of food group intakes showed that there was a decrease in the consumption of whole grains, potatoes, and milk and an increase in the intake of beverages and alcoholic beverages. The risk factors for poor control of HbA1c were the duration of diabetes and co-morbid hypertriglyceridemia in the 4^th survey, whereas subjective health perception, obesity, and hypercholesterolemia as co-morbidities were found to be risk factors in the 7^th in addition to the risk factors highlighted in the 4^th survey. Conclusions: For the future management of elderly Korean diabetes patients, greater care is indicated for men over 75 years, and those with low levels of education. It is necessary to increase the intake of milk and vegetables, and reduce the intake of beverages and alcoholic beverages. In addition, it is necessary to reduce the incidence of obesity, hypercholesterolemia, and hypertriglyceridemia for proper control of blood sugar.

Objectives: This study aimed to verify the impact of dental health care insurance coverage policy by analyzing the changes in dental care utilization and expenditures over 5 years from 2012 to 2016, when the dental health insurance coverage expansion policy was implemented. From the national cohort data collected by the Korea Health Panel Survey, a retrospective study was conducted for all household members using dental services. Methods: This study statistically verified the difference in the dependent variables by frequency analysis, chi-square test, t-test, and one-way analysis of variance (SPSS version 22, IBM Co. USA, p<0.05). Results: The annual utilization rate steadily increased from 23.4% to 26.1% between 2012 and 2016. Although there were differences in utilization rates by gender, age, and income level, patients kept using the dental services in 2016 regardless of the type of health insurance. The average annual copayment for patient expenditures (out-of-pocket amount) increased from ￦463,844 to ￦537,401 in 2012 and 2016, respectively. Of the dental care expenditures over 5 years, the ratio of uninsured expenses by the elderly decreased from 38.5% to 25.9%, and the national health insurance service coverage increased from 40.3% to 49.1%. Conclusions: Although this policy did not reduce overall patient expenditures, it has been found that there was a positive effect on the elderly and low-income groups; it increased the utilization and access to dental services.

Background: The purpose of this study is to examine the characteristics of and factors associated with long-term care (LTC) utilization under public long-term care insurance (LTCI) among end-of-life older adults in Korea. Methods: Using a 5% sample of older people aged 65 or older and their health and LTC insurance data, two-part model analyses were conducted. We compared LTC uses and their determinants during the last year of life among decedents in the year 2010 with those of survivors. We also compared the medical uses of the same sample with their LTC uses. Results: The end-of-life elderly were more likely to use LTC, and their expenditure on LTC was higher than their counterparts. Whether or not older people used LTC during their last year of life was significantly affected by age, sex, health insurance, household income, and living alone; however, LTC costs of the decedents were only affected by functional status, which may have been due to the reimbursement scheme of the current LTCI, which is mainly based on functional dependency level. For the survivors, having chronic diseases significantly increased the likelihood of LTC use, which was not the case for the decedents. End-of-life elderly with relatively low social economic status were more likely to use the LTC other than medical services, while the health conditions affected their medical uses most significantly. Conclusion: The study findings provide key information for predicting demand related to the increasing LTC needs of Korean older people at the end of life.

This study examined the sociodemographic factors, health-related habits, chronic diseases, dietary habits, and nutrient intake according to the self-rated health status in a group aged over 65 years by analyzing the nationally representative Korean survey data. A total of 1,510 subjects were analyzed among the participants of the 2016 Korean National Health and Examination Survey (KNHANES). Statistical analyses for complex samples were performed using the SPSS software package (version 19.0) The study subjects were divided into two groups (healthy group vs. unhealthy group) based on their self-rated health status. The percentage of the healthy group was 66.5%. Gender, age, education level, household income, job (P<0.001, respectively), marital status, and basic living allowance (P<0.05, respectively) were significant sociodemographic variables of the self-rated health status. Alcohol consumption (P<0.01), aerobic physical activity, stress, quality of life, not feeling very well, depression and activity restriction (P<0.001, respectively) were also significant health-related variables of the self-rated health status. Blood glucose, anemia (P<0.05, respectively), and chewing problems (P<0.001) were significant chronic disease-related variables of the self-rated health status. Adequate intakes of protein, dietary fiber, phosphorus, thiamin, niacin, vitamin C (P<0.001, respectively), calcium, sodium, potassium (P<0.01, respectively), iron, vitamin A, and riboflavin (P<0.05, respectively) were also significant variables of the self-rated health status. In complex samples multiple logistic regression analysis, the self-rated health status was influenced significantly by the aerobic physical activity (P<0.01), stress level (P<0.05), depression (P<0.001), quality of life (P<0.001), not feeling very well (P<0.001), activity restriction (P<0.001), chewing problem (P<0.05), and adequate intake of iron (P<0.05). These results suggest that activity restriction, mental health, adequate iron intake, and physical activity may be associated with the self-rated health status in the elderly.

여기서는 많은 수의 비관측사례로부터 발생할 수 있는 표본의 편의(bias) 문제를 탐구한다. 이 연구는 본래 일본 후생성이 1989년 실시한 <가족주기와 가구형태에 대한 인구학적 조사> 자료를 이용하여 노인부보와 자녀간 근접성을 분석하는 목적에서 이루어졌다. 그런데 <가족주기와 가구형태에 대한 인구학적 조사>는 노인부모를 대상으로 한 조사가 아니라 전체 가구 일반에 대한 조사이기 때문에 노인부모에 대한 많은 정보를 손상하고 있었다. 또한 본 조사는 가구주를 통하여 가족원에 대한 정보를 획득하는 방식으로 설계되었기 때문에 가족원에 대한 정보가 완전하지 못하였다. 나아가 비관측사례의 유형을 보면 여러 항목들이 동시적으로 관측되지 않고 있었다. 이와 같이 복합적 메커니즘에서 발생한 비관측 사례는 분석의 편의를 초래할 위험이 크다. 우선, 많은 수의 비관측사례로 표준오차를 잘못 추정할 소지가 크다. 더욱이 사례들이 선택적으로 관측되지 않았다면 관측된 자료에 따른 추정을 심각한 편의를 포함할 수 있다. 이와 같이 손상된 자료로부터 발생할 수 있는 추정 편의를 개선하기 위하여 여기서는 두 가지 기법을 활용하였다. 첫째, 관측치와 공변인간의 관계에 기초하여 비관측사례를 추정하는 방법으로 EM 알고리듬을 활용하였다. 둘째, 관찰의 선택성에서 비롯된 추정 편의를 개선하기 위하여 이단계(two stage) 모형을 활용하였다.
