We investigated the relationship between depression, suicide risk, and related nutrient intakes in 50-60 year old Korean osteoarthritis patients. In the $6^{th}$ National Health and Nutrition Examination Survey, 4,112 people who have been diagnosed with osteoarthritis by a doctor were analysed. Anxiety and depression level, pain and discomport level, depressive mood and suicidal ideation were significantly higher in osteoarthritis group compared to the non-osteoarthritis group(p<0.05). Dietary intake of energy, protein, n-3 and n-6 fatty acids, calcium, phosphate, thiamin, riboflavin, and niacin were significantly higher in the normal group compared with all the osteoarthritis, depression and suicidal ideation groups(p<0.05). The presented convergence strategy would be applied for emotional health and health care improvement of osteoarthritis patients.

This study was performed to investigate the characteristics of nutrient intake according to metabolic syndrome in Korean elderly. Data on 1,200 elderly (men 545, women 655) over 65 years was obtained from the Korea National Health and Nutrition Examination Survey 2010. The subjects were divided into metabolic syndrome (MetS) and normal groups based on NCEP-ATP III guidelines and by applying the Asia-Pacific definition with waist circumference. The prevalence of MetS was 48.9% in all subjects, 35.6% in men and 58.9% in women, respectively. All nutrient intake was significantly lower in MetS than normal subjects, except iron, vitamin A, carotene, and retinol. In the carbohydrate: protein: fat (C:P:F) ratio, MetS showed a higher rate for carbohydrate, but a lower rate for protein and fat than normal. MetS was lower in calcium, vitamin B1, and vitamin C by the nutrient adequacy ratio than normal. Mean adequacy ratio of MetS (0.69) was lower than that of the normal group (0.72). These results demonstrated that undernutrition, not excess intake of specific nutrients - energy, fat, or cholesterol was associated with the risk for MetS in Korean elderly with MetS. Therefore, it is recommended to have a healthy dietary pattern with diverse nutrients for the prevention of MetS.

Objective: This study aimed to analyze the correlation between factors affecting health risk behaviors of rural residents according to regional scale. Methods: Restricted-access data from the 2016~2021 Korea National Health and Nutrition Examination Survey and the multivariate probit model were used. As for health risk behaviors, smoking, drinking, lack of aerobic exercise, low level of healthy eating index, unvaccination, and non-participation in health examination were considered. Results: Controlling for individuals' socio-demographic characteristics, in general, correlation coefficients between unobservable factors affecting health risk behaviors were significant. However, the magnitude and statistical significance of the correlation coefficients varied by regional scale (dong/eup/myeon). This suggests that rural residents engage in health risk behaviors due to their different characteristics compared with urban dwellers, which also varies by whether residents are located in eup or myeon area. Conclusion: It is necessary to differentiate health care services between urban and rural areas in terms of type of service and programs based on the relationship between unobservable factors affecting each type of health risk behaviors.

Objectives: Based on the 7th National Health and Nutrition Examination Survey 1,135 adults aged 19 years were selected as the final study subjects to investigate the relationship between oral health and chewing difficulty in adults. Methods: Frequency analysis, chi-square test, and logistic regression analysis were performed for general characteristics, oral health behaviors, awareness symptoms, and oral health using SPSS Program 21.0. Results: Regarding factors related to chewing difficulty, the oral health was 0.44 times lower than the average level and 0.28 times lower than the good condition. In the case of oral examination, chewing difficulty was 0.85 times lower. The speaking problem was 0.11 times lower in usually than inconvenient and 0.06 times lower in not inconvenient. In the case of un-treatment, it was 0.40 times lower than that in the case of treatment. The chewing difficulty was significantly higher by 2.09 times in the case of experience of tooth pain and 1.36 times in the case of periodontal disease. Conclusions: Based on the above results, it is thought that prevention and treatment are actively needed to identify factors of oral health to improve oral health, to solve chewing difficulty and to improve chewing function.

Objectives: The purpose of this study is to examine and explain the extent of income-related inequity in health care utilization and expenditures to compare the extent in 2005 and 2010 in Korea. Methods: We employed the concentration indices and the horizontal inequity index proposed by Wagstaff and van Doorslaer based on one- and two-part models. This study was conducted using data from the 2005 and 2010 Korean National Health and Nutrition Examination Survey. We examined health care utilization and expenditures for different types of health care providers, including health centers, physician clinics, hospitals, general hospitals, dental care, and licensed traditional medical practitioners. Results: The results show the equitable distribution of overall health care utilization with pro-poor tendencies and modest pro-rich inequity in the amount of medical expenditures in 2010. For the decomposition analysis, non-need variables such as income, education, private insurance, and occupational status have contributed considerably to pro-rich inequality in health care over the period between 2005 and 2010. Conclusions: We found that health care utilization in Korea in 2010 was fairly equitable, but the poor still have some barriers to accessing primary care and continuing to receive medical care.

Vitamin D deficiency is a risk factor for metabolic syndromes. We examined whether vitamin D deficiency altered the prevalence of cardiovascular disease (CVD) in older Koreans. Cross-sectional analysis of data from the Korean National Health and Nutrition Examination Survey IV 2008-2009 was used to examine the association between serum 25-hydroxyvitamin D (25(OH)D) levels and the prevalence of CVD in a representative population-based sample of 5,559 men and women aged ${\geq}50$ years. CVD was defined as angina pectoris, myocardial infarction, or stroke. The prevalence of CVD (7.0%) in the older Korean population was lower than that in the older US population, although average serum 25(OH)D levels were much lower in the Korean population. Additionally, serum 25(OH)D levels did not differ significantly between the CVD and non-CVD groups. However, subjects in the lowest category (< 25 nmol/l) of serum 25(OH)D level had the greatest prevalence of CVD, about two-fold higher than subjects in the highest category (> 75 nmol/l), after adjusting for age, gender, body mass index, education level, residence location, and region. The prevalence of other risk factors for CVD, including higher waist circumference, fasting glucose, low-density lipoprotein (LDL) cholesterol, and triglyceride levels and lower high-density lipoprotein (HDL) cholesterol levels, was also higher among subjects in the lowest category than among those in the highest category. In conclusion, low serum 25(OH)D may be an independent risk factor for CVD in older Koreans.

Purpose: This descriptive survey-based study aimed to identify the factors associated with obese adults' quality of life (QOL) using a secondary analysis of data collected through the 8th Korea National Health and Nutrition Examination Survey (2019). Methods: In this study, factors affecting the health-related quality of life of obese adults were analyzed by categorizing them into three independent variables: general characteristics, health behaviors, and mental health characteristics. Using t-test and analysis of variance (ANOVA), an analysis was performed to determine the differences in obese adults' QOL depending on their general characteristics, health behaviors, and mental health conditions. A hierarchical regression analysis was performed to identify the factors that affect obese adults' QOL. Results: In obese adults' general characteristics, the risk factors for QOL were older age, male, lower-income level, presence of spouse, and occupation. With regard to health behaviors, the risk factors were lack of exercise. In terms of mental health conditions, the risk factors were stress and suicidal ideation. Conclusion: Obese adults' QOL was affected by age, sex, income level, absence/presence of a spouse, occupation, health behaviors (e.g., exercise), and mental health conditions (e.g., stress and suicidal ideation).

Purpose: Food intake of COPD patients decreases because of appetite loss, depression, and breathing problems while eating, which increase the likelihood of patients becoming malnourished. This study investigated the nutrient intake and dietary quality of people with and without COPD in Korea. Methods: There were 2,160 adults aged 50 and over who participated in the $5{\sim}6^{th}$ Korea National Health and Nutrition Examination Survey. The subjects were divided into the COPD group and non-COPD group according to the rate of forced expiratory volume at 1 second (FEV1) against forced vital capacity (FVC). Consumption of food and nutrients were calculated based on the nutrition examination survey. Statistical analyses were conducted using SPSS 19.0. Results: Among individuals in their 50s, intake of vitamin $B_1$ in the COPD group was significantly less than the NCOPD group, while intake of sodium in the COPD group was significantly greater than the NCOPD group. Among individuals in their 60s, the energy intake of the COPD group was significantly less than that of the NCOPD group. The COPD group showed significantly less intake of vitamin $B_1$ and vitamin C, but greater intake of sodium than the NCOPD group. In the group aged 70 and over, The COPD group had significantly less intake of vitamin $B_1$ than the NCOPD group and showed lower nutrient adequacy ratio values in protein, vitamin $B_1$, vitamin $B_2$, and iron than the NCOPD group. Conclusion: The COPD group consumed less energy and certain nutrients, and their dietary quality was poor compared to the NCOPD group. Thus, more detailed research is required to understand the concrete relationship between COPD and malnutrition.

Objectives: This study examined the determinants of quality of life, depending on the presence or absence of asthma in adults, based on secondary wave data. Methods: Among the 21,724 people participating in the 6th Korea National Health and Nutrition Examination Survey as it was conducted from the first to third period, 495 participants who were aged 19 or older and responded to the question of the presence or absence of asthma were included in the final analysis. Demographic characteristics were examined using the SPSS/WIN 23.0 software tool for analysis of complex sample survey data. Health-related characteristics were presented using descriptive and multivariate analysis of data. Rao_Scott ${\chi}^2$ was used for the analysis of differences in quality of life, and multiple regression analysis of complex sample survey data was used to analyze factors affecting quality of life. Results: The variable factors negatively influencing quality of life were aging, cognition of their ill health, and limited activities. Conclusions: Based on the analysis, the study suggests that practical and ongoing nursing intervention proposals to improve the quality of life of asthmatic patients should be implemented not only for physical limitations and aging but also for psychological factors that reflect subjective health statuses.
