This study conducted a secondary analysis using original data of performed by Korea Institute for Health and Social Affairs to determine factors affecting oral health-related quality of life and mental health in the elderly. The research subjects were 1,217 people who were over 65 years old and completed an oral examination and oral questionnaire survey. The results were as follows. First, mental health problems arise in people with an oral health status designated as 'bad' or when they feel 'very uncomfortable' chewing or speaking. Second, the quality of life decreases as problems with chewing and speaking increase. The results reveal that to reduce problems of mental health(stress, depression, suicide) and to enhance the quality of life, there is a need to develope diverse programs for preventive treatment and oral health education. What is the most important is consistent policy support.

Objectives: This study aimed to evaluate the relationship between pit and fissure sealants of the molars, and caries prevalence and experience to assess the effect of sealants on caries prevention. Methods: Data from 16,119 people were extracted from the seventh Korean national health and nutrition examination survey, which was conducted from 2016 to 2018. Demographic, socioeconomic, oral health-related behavioral, and oral examination survey data were collected as independent variables. SAS statistics for complex samples and multiple logistic regression analysis (Windows ver. 9.4) was used for the statistical analyses. Results: Caries prevalence and experience were significantly associated with age, sex, daily toothbrushing frequency, interdental cleaning, and having molar sealant. Multiple logistic regression analysis revealed a significant association between having molar sealants and the caries prevalence and experience among participants under 30 years of age after adjusting socio-economic variables and toothbrushing-related factors. Conclusions: This study confirmed the effect of molar sealants on caries prevention in Korea. Our results support that the application of molar sealants in children, adolescents, and young individuals is effective in preventing caries.

This study is the secondary statistical analysis calculating the quality of life of patients with cancer by giving the integrative weight based on National Health and Nutrition Examination Survey data of the Centers for Disease Control for five years from 2007 to 2011 for the first time in Korea. The results of measurement showed that the number of cancer patients was 201, which accounted for about 0.8 % of 26,260 subjects. The quality of life of cancer patients was higher when they had lower age(p<0.0001), more professional occupations(p<0.0001), and higher educational history(p=0.0002). When they lived in apartment(p<0.0001), got unmarried(p<0.0001), the quality of life was higher. In particular, the measurement of quality of life of cancer patients based on type of health insurance was the result of new study for the first time in Korea.

Purpose: This study utilizes big data from the 8th (2021) National Health and Nutrition Examination Survey to determine first, the relationship between chewing discomfort in the elderly and some systemic diseases and second, whether oral diseases and oral health problems are related to systemic diseases. Since this may have an impact, we aim to provide basic data to facilitate the expansion and emphasize the importance of integrated health management education. Methods: Original data from the 8th (2021) National Health and Nutrition Survey, conducted by the Korea Centers for Disease Control and Prevention, were analyzed using SPSS Version 21.0 (IBM). A complex sample frequency analysis was conducted to confirm the general and health-related characteristics of the study subjects, and a complex sample cross-analysis was conducted to determine chewing discomfort according to both general and health-related characteristics. Complex sample multiple logistic regression analysis was conducted to determine the effect on chewing discomfort. Results: In order to analyze the factors that affect chewing discomfort, the general characteristics that showed significant differences in chewing discomfort were adjusted for age, personal income, education level, basic livelihood security, high blood pressure, subjective health status, and subjective oral health. It was found that the condition had a statistically significant effect on chewing discomfort. Conclusion: The findings of this study demonstrate that high blood pressure, subjective health status, and subjective oral health status affect chewing discomfort; hence, measures such as developing and operating programs to improve national oral health are needed. We hope that our study will be used as basic data for research into chewing discomfort and systemic diseases in the elderly.

The purpose of this study was to analyze average kimchi intake, general characteristics, frequency of daily meal intake, intakes of vegetables and fruits, and nutrient intakes in four serving size groups based on data from the Korea National Health and Nutrition Examination Survey 2010~2012. The results showed an average amount of kimchi intake in subjects of 115.6 g, ranging from 0 g to 605.94 g. For daily meal intake except snacking according to kimchi serving size, all daily meal intakes increased significantly with increasing kimchi serving size (p<0.0001), and tendency of kimchi intake increased with more eating-out. As kimchi serving size increased, total intakes of vegetables and salted vegetables increased significantly (p<0.0001). However, unsalted vegetables intake did not show significant difference. Intake of fruits also increased with increasing kimchi serving size. As the serving size of kimchi increased, intakes of energy, carbohydrates, protein, fat, sodium, and potassium increased significantly (p<0.0001). For intake of sodium, intakes of all groups exceeded 2,000 mg, which is the recommended level for Koreans. Moreover, the fourth serving size group consumed three times (6,546.35 mg) more sodium than the recommended level.

Objective: Despite government efforts to increase participation in gastric cancer screening, the rate is still suboptimal in Korea. Therefore, we explored barriers to and predictors of gastric cancer screening participation among a nationally representative sample. Methods: We used the Health Interview Survey sub-dataset derived from the Fourth Korean National Health and Nutrition Examination Survey 2008 (KNHANES IV) to evaluate participation in gastric cancer screening and factors associated with attendance in individuals age ${\geq}40$ years. We enrolled 4,464 subjects who completed the questionnaire and were not previously diagnosed with gastric cancer. Four groups of factors were considered potential predictors of gastric cancer screening in a multivariate analysis: sociodemographic, health behavior, psychological and cognitive, and dietary factors. Results: Overall, 41.3% complied with the gastric cancer screening recommendations. Younger age, lower education level, living without a spouse, frequent binge drinker, and current smoker were significantly associated with less participation in gastric cancer screening. Conclusions: To improve participation in gastric cancer screening, more focused interventions should be directed to vulnerable populations, such as groups with low socioeconomic status or unhealthy behavior. In addition, there should be new promotional campaigns and health education to provide information targeting these vulnerable populations.

This study analyzed the health characteristics and comorbidity of adult men aged 40 years by dividing them into a control group of those without any disease related to fine dust and a patient group with one or more diseases related to fine dust in areas with high levels of fine dust pollution using the sixth and seventh Korea National Health and Nutrition Examination Survey (2013-2017). Among the general characteristics, the mean age of the patient group was significantly older than that of the control group (p<0.001), and in terms of the health-related characteristics, the frequency of breakfast consumption in the patient group was higher than in the control group (p<0.043). The body measurements were similar in the patient and control groups. Regarding the prevalence of comorbidity, the patient group showed a higher prevalence of hypertension, dyslipidemia, stroke, myocardial infarction, heart failure, and diabetes than the control group, but the differences were not statistically significant. On the other hand, the prevalence of other cancers (except stomach cancer, liver cancer, colorectal cancer, breast cancer, and cervical cancer) in the patient group was higher than in the control group (p<0.05). In terms of the clinical characteristics, the glycated hemoglobin levels in the patient group were significantly higher than in the control group (p<0.048). Information on nutrition and health in areas with frequent occurrences of fine dust was obtained through the study results, which can be used as basic data for measures of health and diet management against diseases that will increase in relation to fine dust.

BACKGROUND/OBJECTIVES: Magnesium is an essential nutrient for human health. However, inadequate intake is commonly reported worldwide. Along with reduced consumption of vegetables and fruits and increased consumption of refined or processed foods, inadequate magnesium intake is increasingly reported as a serious problem. This study aimed to assess magnesium intake, its dietary sources, and the adequacy of magnesium intake in Korean populations. SUBJECTS/METHODS: Data was obtained from the Korea National Health and Nutrition Examination Survey 2016-2019 and included individuals aged ≥1 yr who had participated in a nutrition survey (n=28,418). Dietary intake was assessed by 24-h recall, and dietary magnesium intake was estimated using a newly established magnesium database. Diet adequacy was evaluated by comparing dietary intake with the estimated average requirement (EAR) suggested in the Korean Dietary Reference Intakes 2020. RESULTS: The mean dietary magnesium intake of Koreans aged ≥1 yr was 300.4 mg/d, which was equivalent to 119.8% of the EAR. The prevalence of individuals whose magnesium intake met the EAR was 56.8%. Inadequate intake was observed more in females, adolescents and young adults aged 12-29 yrs, elders aged ≥65 yrs, and individuals with low income. About four-fifths of the daily magnesium came from plant-based foods, and the major food groups contributing to magnesium intake were grains (28.3%), vegetables (17.6%), and meats (8.4%). The top 5 individual foods that contributed to magnesium intake were rice, Baechu (Korean cabbage) kimchi, tofu, pork, and milk. However, the contribution of plant foods and individual contributing food items differed slightly by sex and age groups. CONCLUSIONS: This study found that the mean dietary magnesium intake among Koreans was above the recommended intake, whereas nearly one in 2 Koreans had inadequate magnesium intake. To better understand the status of magnesium intake, further research is required, which includes the intake of dietary supplements.

It is generally accepted that diet modification provides beneficial effects on the management of diabetes. In the present study, we evaluated the effects of diet modification on nutrient intake and quality of life in a large sample of diabetic patients. This study was conducted using data from the Korea National Health and Nutrition Examination Survey IV and V (2007-2010). A total of 2,484 of diabetic patients were included in the analysis. Then, we compared the overall quality of dietary intake between diabetic patients with diet modification and those without dietary modification. The result showed that subjects on diabetic diet (DDG) showed lower levels of total cholesterol, triglyceride, and AST before and after the adjustment for covariates (all p < 0.05). The results of nutrient assessment showed that DDG had lower intakes of total energy, fat, and carbohydrate (all p < 0.05), but higher intakes of energy from protein, vitamin B1, vitamin B2, niacin and vitamin C than NDG. (all p < 0.05). In addition, nutritional adequacy ratio of calcium and vitamin B2 were significantly higher in DDG than those in normal diet group (NDG) (p < 0.05). However, we observed no significant differences in quality of life between two groups. In conclusion, diet modification in diabetic patients seemed to be effective to improve blood lipid profile and the adequacy of nutrient intake without sacrificing the quality of life.

The purpose of this study was to investigate the current status of chronic diseases according to obesity in the elderly older than age 65 using data from the 7th Korea National Health and Nutrition Examination Survey (2016~2018). The subjects of the survey were 3,245 elderly older than age 65 who participated in the health survey and nutrition survey, 45.8% of the subjects were males and 54.2% of the subjects were female. 37.5% of all the elderly were obese, and the females (42.4%) were more obese than the males (31.8%) (p<0.001). Diabetes, hypertension, and hypertriglyceridemia had a similar prevalence of 24.6%, 63.0%, and 12.7% in males and females, respectively. Hypercholesterolemia was higher in the elderly females (44.2%) than in the elderly males (24.9%) (p<0.001). Through the logistic regression analysis, it was found that the prevalence of chronic diseases was higher in obesity than normal in elderly males and females (p<0.001). The total food intake increased from 'under weight' to 'obesity' in males (p<0.01) and females (p<0.001). In the case of the elderly males, the higher the degree of obesity, the higher the energy intake (p<0.05), and 'pre-obesity' consumed the most energy in elderly females. As a result of this study, the higher the obesity rate of the elderly, the higher the prevalence of chronic diseases.
