The purpose of this study was to analyze the effect of chewing difficulty on osteoarthritis in Korean adults. Data from the National Health and Nutrition Examination Survey for two years from 2019 to 2020. The collected data were analyzed using the SPSS (21.0) program using composite samples, and the mean crossover analysis and logistic return analysis were performed. An analysis of the effects of chewing difficulty on osteoarthritis in korean adults showed that those with chewing difficulty had a 2.02 fold higher risk of osteoarthritis (95%CI=1.56~2.42) and a statistically significant difference (P<0.05). The association between the chewing difficulty on osteoarthritis could be confirmed, and measures improve of the oral health and preventing osteoarthritis should be prepared.

There were numerous evidences that subjective health evaluation was a powerful indicator for morbidity and mortality in many countries. Since self-rated health (SRH) was a reasonable health measure, identifying predictors for SRH would be beneficial for assessment of overall health, monitoring health status, and development of health promotion programs. Health risks, health behavior, socioeconomic characteristics and social capital were potential indicators for SRH. We examined association. between SRH and indicators such as health risk factors, subjective living condition, income, education level and dietary variety score. Total 4,262 subjects, aged between 20 and 69 years old, were selected from KNHANES 2001; those who completed health examination, nutrition survey, and provided their socioeconomic information. Results of logistic regression showed that it was likely to have better SRH for those who were younger, male and have higher education, higher income, better living condition, no metabolic syndrome and higher dietary variety.

The objective of this study was to investigate difference in the diet by the kind of meal and the economic status. Nutrient contents at each meals were compared and differences in food intake at different meal were analyzed by economic status. Data from the 1998 Korean National Health Examination Nutrition Survey were used. Using the poverty line based on the 1998 Korean minimum cost of living, the subjects (n = 10400) were classified into high class (36.1％), middle class (40.7％) and low class (23.1 ％). Most nutrient intakes were obtained for main meals regardless of economic status. For high class, breakfast, lunch, dinner and snacks bring about 21, 29, 30 and 19 ％ of total energy intake, for middle class 22, 29, 30 and 19％ and for low class 24, 30, 30 and 16％, respectively. The high-middle class people tend to get more food intakes and nutrients at dinner and snacks, while the low class at main meals. This result was associated with the consumption of a smaller number of meals and a greater number of snacks daily as the economic level was going up (p 〈 0.05). Meals contributed to energy, protein and fat intake, and snacks to water, retinol and vitamin C. The food intakes by food group were different at meals by economic class. Seaweed product were popular breakfast foods in both middle and low groups. Thus three meals such as breakfast, lunch and dinner still delivered most of the energy and most of the macro-nutrients regardless of economic status.

The purpose of this study was to test whether moderate alcohol consumption has any positive effect on lowering blood pressure among Koreans. Study subjects were Korean adults 20 years or older (n=5,234) who participated in the 2001 Korean National Health and Nutrition Examination Survey (KNHANES). Analysis of variance and analysis of covariance were used to construct univariate and multivariate models relating alcohol consumption to blood pressure for the analysis. After adjustment for possible covariates, drinkers (regardless of drinking level) had significantly higher systolic and diastolic blood pressure, compared with never-drinker for male subjects. Diastolic and systolic blood pressures were also significantly elevated with the drinking frequency and amount of alcohol intake among male subjects. For the female subjects, only diastolic blood pressure was significantly associated with the alcohol consumption at multivariate model. however, low level alcohol consumption did not show any sign of lowing effects on blood pressure. The result implies that moderate alcohol consumption did not have any positive effect on lowering blood pressure among Koreans for either sex.

The purpose of this study was to examine the status of coffee intake in South Korea by analyzing the 4th Korea National Health and Nutrition Examination Survey. The results showed that 52.3% of Koreans consumed coffee at least once a day. Males consumed coffee more frequently than females and those aged 20-39 years and 40-59 years consumed coffee most frequently. Coffee drinkers consumed coffee two times a day and 138 mL each time on average. Coffee was mainly consumed either at home (44.8%) or in the workplace (36.1%); males drank coffee most frequently in the workplace and females did so at home. Milk coffee including coffee from vending machines and coffee mix (73.8%) was the most common type of coffee consumed. The results of this study would extend the understanding of the general status of coffee intake in South Korea, which has shown steady growth but remains a relatively overlooked research area.

Objectives: The purpose of this study was to analyze the effect of chewing difficulty on depression in Korean adults to provide basic data on improving the quality of life related to oral health of Korean adults. Methods: The raw data of the analysis were obtained from the dataset of the seven Korea National Health and Nutrition Examination Survey conducted between 2016 and 2018. The subjects included 9,535 people who underwent oral examination and answered questions. The collected data were analyzed using the SPSS (ver 21.0) program using composite samples, and the mean crossover analysis and logistic return analysis were performed. Results: An analysis of the effects of chewing difficulty on depression in Korean adults showed that those with chewing difficulty had a 2.24 fold higher risk of depression (95% CI: 1.73-2.90) and a statistically significant difference (p<0.05). Conclusions: The association between the chewing difficulty on depression could be confirmed, and measures improve of the oral health and preventing depression should be prepared.

BACKGROUND/OBJECTIVE: This study analyzed health-related factors for metabolic syndrome (Mets) among workers in South Korea. SUBJECTS/METHODS: This analysis included 4,666 adults aged 19-64 years to analyzed health-related risk factors for Mets from the Korean National Health and Nutrition Examination Survey (2016). The sociodemographic, working, health-related, and biochemical characteristics were presented as percentages (%) by chi-square tests. Multiple logistic regression analysis was performed to analyze the 95% confidence intervals (CIs) and associations between health-related factors characteristic of workers and the odds ratios of Mets. RESULTS: An increased prevalence of Mets was associated with male day workers compared to male shift workers (1.726-fold increase, 95% CI: 1.077-2.765), and with ${\geq}8hrs/day$ sleep duration compared to < 6 hrs/day sleep duration in female workers (2.133-fold, 95% CI: 1.041-4.368). In addition, reduced odds of high Mets were associated with male workers consumed of breakfast 5-7 times/wk compared to those consumed < 1 time/wk (0.593-fold decrease, 95% CI: 0.372-0.944). CONCLUSIONS: Health-related factors (sleep duration, frequency of breakfast) and working type in Korean workers may affect the prevalence of Mets.

This study was conducted to investigate that the nutrition labeling use is associated with demographic and psychosocial factors according to each nutrition information on the nutrition labeling in Korean adults. The study subjects (N=1,140) were individuals who were aged 20 years and more and answered on the question of nutrition label use and who participated in the Korean National Health Examination and Nutrition Survey (KNHANES) in 2010.As age older, there was more interest in information such as sugar, protein, fat, cholesterol than calories. In contrast, as age younger, there was more interest intrans-fat, sodium as well as calories. As higher education level, there were more aware of trans-fat, sodium and calories. From the result that the most interested nutrition items were significantly different by democratic factors, we could understand interested nutrient information on the nutrition labels could change according to individual specific education. Therefore, this can also provide basic data for systematic education program by nutrition label use.

The objective of this study was to develop a semi-quantitative food frequency questionnaire (FFQ) for an adult population for use in the Korea National Health and Nutrition Examination Survey (KNHANES). The 24-hour recall data for 2,939 subjects aged 19 years and over from the fourth KNHANES first year (2007) were used to extract the items included in the questionnaire. The FFQ items were developed by selection of major dishes based on the cumulative contribution rate, between-person variability based on the cumulative R2 of energy and 14 nutrients (carbohydrate, protein, fat, crude fiber, calcium, phosphorous, iron, sodium, potassium, vitamin A, thiamin, riboflavin, niacin, and vitamin C) and the number of consumers of each dish. In addition, the FFQ items were revised with analysis of 24-hour recall data of the fourth KNHANES second and third year (2008, 2009). Finally, 112 items were included in the FFQ and grouped as follows: rice (5 items), noodles and dumplings (6), breads and rice cakes (8), soups and stews (12), soybeans, eggs, meat and fish (23), vegetables, seaweed and potatoes (27), milk and dairy products (4), fruits (13), beverages (5), snacks (6) and alcoholic beverages (3). The food items of FFQ accounted for an average of 87.0% of energy and 14 nutrient intakes and also accounted for 81.7% of the between-person variability. The frequency range of the FFQ items was classified into nine categories (never or seldom, once per month, 2-3 times per month, once per week, 2-4 times per week, 5-6 times per week, once per day, twice per day and three times per day) and the portion size was divided into three categories (small, medium and large). We expect that this developed dish-based FFQ could be used in assessment of longterm dietary intakes of Korean adults.
