Purpose: The study was conducted to identify factors influence suicidal ideation among older adults with osteoarthritis. Methods: This study used a cross-sectional design with secondary analysis of the Korean National Health and Nutrition Examination Survey. Data for 174 men and 939 women who aged${\geq}65$, and were diagnosed osteoarthritis from the Korea National Health and Nutrition Examination Survey 2010~2012 were included. Suicidal idea, age, sex, education, marital status, living alone, income, body mass index, smoking and alcohol use, exercise, perceived health status, activity limitation, joint pain and stiffness, depressive mood, and perceived stress were measured. Influencing factors and odds ratios were analyzed using complex sample multivariate logistic regression. Results: In the results, 29.9% of the elderly with osteoporosis had suicidal idea. The adjusted odds ratios (ORs) of suicidal ideation were significantly higher among those over 80 years older (OR=2.88, 95% CI=1.49~5.58), those with depression (OR=4.01, 95% CI=2.66~6.04), and those with high levels of stress (OR=2.76, 95% CI=1.79~4.24). Conclusion: Therefore, older adults with osteoarthritis should be screened for depression and stress to decrease suicidal ideation and prevent suicide attempt.

There is little information on dietary vitamin K intake and nutritional status of daily requirements of vitamin K in Korea. The objective of this study was to investigate the vitamin K intake and major food sources of Vitamin K in Koreans. The survey data from the 2010-2011 Korean National Health and Nutrition Examination Survey of 7,792 subjects (aged 19-64 years) were examined. Total vitamin K intake was calculated from 24-hour dietary recall using a vitamin K food database, Computer Aided Nutritional analysis Program and the United States Department of Agriculture database. The geometric mean of vitamin K was estimated as $322.40{\pm}6.33ug/day$ for men and $271.20{\pm}4.92ug/day$ for women. Daily vitamin K intake increased significantly with age (p for trend < 0.001). The main food source of vitamin K was vegetables (72.84%), including cabbage kimchi (19.26%), spinach (17.38%), sesame leaves (7.11%), radish leaves (6.65%), spring onions (6.28%), and laver (4.82%), followed by seaweed, seasonings, and fat and oils. We observed that the vitamin K intake of Koreans was relatively higher than that reported by other studies in Western countries and differed depending on age.

BACKGROUND/OBJECTIVES: The purpose of this study was to investigate the association between socioeconomic status and chewing discomfort and identify the role of food insecurity in the association's causal pathway in a representative sample of Korean elders. MATERIALS/METHODS: We conducted cross-sectional analyses of the Korea National Health and Nutrition Examination Survey (2013-2015) data for elders aged ≥ 65 years. Socioeconomic status indicators used included household income and education level. Chewing discomfort was assessed according to the self-reported presence of chewing problems. Food security was surveyed using a questionnaire based on the US Household Food Security Survey Module. RESULTS: The odds ratios of chewing discomfort in the 1st and 2nd income quartiles were 1.55 (95% confidence interval [CI], 1.15-2.10) and 1.40 (95% CI, 1.03-1.90), respectively, compared to participants in the highest income quartile. Participants with the lowest education level were 1.89 (95% CI, 1.30-2.75) times more likely to have chewing discomfort than those without chewing discomfort. After including food security in the final model, the logistic coefficients were attenuated in the income and education quartiles. CONCLUSIONS: Low socioeconomic status was associated with chewing discomfort. In addition, the results confirm that food insecurity can mediate the association between socioeconomic inequalities and chewing discomfort among the elderly.

Dining-out behavior is associated not only with socio-demographic characteristics such as gender, education, occupation, residence, and marital status, but also with individual preferences, such as eating-out activities, interests, and opinions. We investigated dining-out behaviors and their associated factors. Announcements by health practioners and the Chief of Dong Office were used to recruit 739 residents (217 males and 522 females) in Chuncheon, Korea. Information on the frequency and reasons for eating out, the standards for meal selection, and the overall satisfaction with restaurants, based on taste, nutrition, amount, price, service, sanitation, and subsidiary facilities of restaurants, was obtained through personal interviews with a structured questionnaire. Among all respondents, 46.3% of subjects ate outside of the home once or twice a month, and 33.8% reported that they ate out only a few times a year, or never. This was much higher than the national average of 52.0% as reported by the Korean National Health and Nutrition Survey (KNHNS) in 2001. The frequency of eating out differed significantly according to age (p=0.001), family income (p<0.001), residential area (p<0.001), and educational level (p<0.001). The most common reasons for dining out were meetings (46.7%), followed by special celebrations (15.4%), and enjoyment (11.2%). Korean food (55.3%) was the most frequently selected type of meal when eating out, and food was most often selected based on personal preferences (41.4%) and taste (29.8%); only 5.5% and 7.7% of subjects considered nutrition or other factors (e.g., sanitation), respectively. The results showed that the frequency of eating out for Chuncheon residents was much lower than the national average; in addition, eating-out behaviors depended on the residents' socio-demographic and personal characteristics.

Objectives: I examined the health and oral health status of elderly people living alone compared to elderly people living with their families by using data (2014) from the 6th Two-Year Korea National Health and Nutrition Examination Survey. Methods: Among 1,454 health survey respondents aged 65 years and over who participated in the 6th Two-Year Korea National Health and Nutrition Examination Survey conducted in 2014, 311 were elderly people living alone and 1,143 were elderly people living with their families. Results: In terms of socio-demographic characteristics, the percentage of elderly people living alone was high especially in women and when the subjects' age, education level, and income level were low. In terms of oral health status, the percentage of elderly people living alone was high when elderly people thought that their subjectively viewed health was poor and the frequency of drinking and exercise was low. In terms of oral health status, the percentage of elderly people living alone was high among elderly people who did not have good oral health in their subjective view and did not get oral examinations for a year and had a lot of difficulty chewing. Conclusions: Family support or additional social support for elderly people who live alone should be considered to promote the healthy lives of elderly people.

The prevalence of metabolic syndrome (MetS) and its cost are increasing due to lifestyle changes and aging. This study aimed to develop a deep neural network model for prediction and classification of MetS according to nutrient intake and other MetS-related factors. This study included 17,848 individuals aged 40-69 years from the Korea National Health and Nutrition Examination Survey (2013-2018). We set MetS (3-5 risk factors present) as the dependent variable and 52 MetS-related factors and nutrient intake variables as independent variables in a regression analysis. The analysis compared and analyzed model accuracy, precision and recall by conventional logistic regression, machine learning-based logistic regression and deep learning. The accuracy of train data was 81.2089, and the accuracy of test data was 81.1485 in a MetS classification and prediction model developed in this study. These accuracies were higher than those obtained by conventional logistic regression or machine learning-based logistic regression. Precision, recall, and F1-score also showed the high accuracy in the deep learning model. Blood alanine aminotransferase (β = 12.2035) level showed the highest regression coefficient followed by blood aspartate aminotransferase (β = 11.771) level, waist circumference (β = 10.8555), body mass index (β = 10.3842), and blood glycated hemoglobin (β = 10.1802) level. Fats (cholesterol [β = -2.0545] and saturated fatty acid [β = -2.0483]) showed high regression coefficients among nutrient intakes. The deep learning model for classification and prediction on MetS showed a higher accuracy than conventional logistic regression or machine learning-based logistic regression.

Purpose: The purpose of this study was to analyze the meal types by cooking methods provided at different meal provision places using the 2015 Korea National Health and Nutrition Examination Survey. Methods: A total of 42,441 meal data on adults from the 2015 Korea National Health and Nutrition Examination Survey were used for analysis. The data were analyzed by complex sample $x^2-test$ of independence and complex sample logistic regression analysis using SPSS 23.0 for Windows. Results: The meal provision place showing the highest frequency was home (60.2%), followed by commercial (32.5%) and institutional foodservices (7.3%). The meal types by cooking method most frequently consumed were rices (18.3%) and kimchis (16.6%). The results of the complex sample logistic regression analysis showed that breads & snacks, steamed or braised dishes, fried dishes, and fresh seasoned vegetables were more likely to be consumed at commercial or institutional foodservices than at home. In addition, noodles & dumplings were more likely to be consumed at commercial places, and Korean soups were consumed at institutional foodservices. Conclusion: From the results of this study, it is suggested to develop recipes for substitution of fried dishes and to develop low sodium recipes at commercial and institutional foodservices. In addition, education of consumers of commercial foodservice is needed to reduce consumption of fried dishes, salted seafoods, and pickled vegetables and encourage consumers to choose meals from institutional foodservice managed by dietitians.

Objectives: The purpose of this study was to evaluate the association between asthma and dental caries by using data from the Korean National Health and Nutrition Examination Survey (KNHANES), from 2013 to 2015. Methods: The study included 11,731 subjects who were ${\geq}19$ years of age and analyzed their demographic-, socioeconomic-, health-, and oral health care-related data. The chi-squared test and logistic regression analysis were conducted using complex sample analyses to examine the relationship between asthma and dental caries. Results: Compared with the control group, the risk for dental caries in the asthma group was 1.207 times higher, regardless of various confounding factors (p<0.001). In the asthma group, the mean DMFT score was significantly higher than that in the control group (p<0.001). After adjusting for confounding factors, the mean number of DMFT in subjects with asthma was 7.67, which was higher than that in subjects without asthma (7.28) (p<0.001). Conclusions: The study results show that asthma may be a risk factor for dental caries. Therefore, in order to prevent dental caries in asthma patients, oral hygiene education is important.

The purpose of this study was to investigate the differences in food and nutrient intake by smoking status among Korean. Food and nutrient intake in relation to smoking status was studied in 7,370 adults, aged 20 years and older in 1998 Korean National Health and Nutrition Survey, in which 24 hour recall method was used for dietary survey. Information of subject's smoking status was collected by interview as a part of health behavior survey. Analysis of variance was used to test the differences in food and nutrition intake among subjects following after Duncan's multiple range test among four different smoking exposure categories. Food intake of male ex-smoker was the highest in most of the food groups among the four groups of daily current smoker, occasional current smoker, ex-smoker and never smoker. There was significant differences observed in food intake of sugar, fruits, beverage, seasoning by the smoking status. It had been also observed that significantly high intake of energy from carbohydrate in non smoker compare to current smoker especially in male subjects. Fiber and vitamin C intake was also higher among non-smoker (never smoker and ex-smoker) than current smoker. In general, food and nutrient intake pattern of ex-smoker resembled those of never smoker than those of current smoker. Not likely the observation from European and American studies, fat intake was not statistically different between smoker (current) and non-smoker (ex-smoker and never smoker) among Korean.
