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.

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: This study aims to examine hypertension patients' quality of life by using the data of the 7^th Korea National Health and Nutrition Examination Survey (1^st year, 2016), identify the factors related to this, and utilize the results as basic data for intervention that can improve hypertension patients' quality of life. Methods: For the research subjects, this study extracted 1,531 patients who were diagnosed with hypertension by a doctor from the total sample of 8,150 participants of the 7^th Korea National Health and Nutrition Examination Survey, and selected 1,072 patients with no missing value in the variables to be analyzed as the final research subjects. The SPSS(version25.0) program was used for the analysis of the collected data. Then, this study used a backward elimination multiple regression analysis method that applied complex sample, to examine the factors related with the finally estimated quality of life. Results: The results of this study revealed that hypertension patients' quality of life was related with age, occupation, spouse, household income, weight gain, restriction of activity, subjected health status, perceived stress, and presence of comorbidity. The final model explained 37.0% of the variance (Wald F=30.012 p<.001). Conclusions: When an intervention program is implemented for the improvement of hypertension patients' quality of life in the future, it will be effective to construct the program according to age group, employment, marital status and household income. As for the program operation, patients should get help therefrom to control weight, facilitate activities and relieve their stress, and they should be also motivated to feel healthy. Furthermore, education should be offered so that they appropriately manage their underlying disease at an early stage.

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.

Objectives: This study aims to examine diabetic patients' quality of life by using the data of the 8th Korea National Health and Nutrition Examination Survey (1st year, 2019), identify the factors related to this, and utilize the results as basic data for intervention that can improve diabetic patients' quality of life. Methods: For the research subjects, this study extracted 624 patients who were diagnosed with Diabetes by a doctor from the total sample of 8,110 participants of the 8th Korea National Health and Nutrition Examination Survey. The SPSS(version25.0) program was used for the analysis of the collected data. Then, this study used a backward elimination multiple regression analysis method that applied complex sample, to examine the factors related with the finally estimated quality of life. Results: The results of this study revealed that diabetic patients' quality of life was related with gender, age, occupation, restriction of activity, subjected health status. The final model explained 35.7% of the variance (Wald F=28.210, p<.001). Conclusions: In order to improve the quality of life of diabetic patients, it would be desirable to provide differentiated management by developing a customized intervention strategy that takes into account gender, age, and occupation. When managing diabetic patients, the state, local governments, and hospitals should include content that prevents and copes with restrictions on activities that may occur due to disease. In addition, it is required to prepare a strategy to induce positive perception of the subject's own health status.

In many cases, the measurement error variances may be functions of the unknown true values or related covariates. This paper considers design-based estimators of the parameters of these variance functions based on the within-unit sample variances. This paper devotes to: (1) define an error scale factor $\delta$; (2) develop estimators of the parameters of the linear measurement error variance function of the true values under large-sample and small-error conditions; (3) use propensity methods to adjust survey weights to account for possible selection effects at the replicate level. The proposed methods are applied to medical examination data from the U.S. Third National Health and Nutrition Examination Survey (NHANES III).

Objectives: The inherent nature of the Korean National Health and Nutrition Examination Survey (KNHANES) design requires special analysis by incorporating sample weights, stratification, and clustering not used in ordinary statistical procedures. Methods: This study investigated the proportion of research papers that have used an appropriate statistical methodology out of the research papers analyzing the KNHANES cited in the PubMed online system from 2007 to 2012. We also compared differences in mean and regression estimates between the ordinary statistical data analyses without sampling weight and design-based data analyses using the KNHANES 2008 to 2010. Results: Of the 247 research articles cited in PubMed, only 19.8% of all articles used survey design analysis, compared with 80.2% of articles that used ordinary statistical analysis, treating KNHANES data as if it were collected using a simple random sampling method. Means and standard errors differed between the ordinary statistical data analyses and design-based analyses, and the standard errors in the design-based analyses tended to be larger than those in the ordinary statistical data analyses. Conclusions: Ignoring complex survey design can result in biased estimates and overstated significance levels. Sample weights, stratification, and clustering of the design must be incorporated into analyses to ensure the development of appropriate estimates and standard errors of these estimates.

Purpose: The purpose of this study was to investigate the characteristics and grip strength of people with osteoarthritis and rheumatoid arthritis using data from the Korea National Health and Nutrition Examination Survey. Methods: This was a retrospective study that analyzed raw data from the first year of the 8th Korea National Health and Nutrition Examination Survey (2019). The study population was 780 people in total, ranging in age from their teens to their 80s. These were people who had been diagnosed with osteoarthritis and rheumatoid arthritis, and the presence of arthritis in and grip strength of these subjects were determined using the average value of three measurements. Results: According to the National Health and Nutrition Examination Survey, the prevalence of arthritis in Korea was 2.5% in men, 10.7% in women, and 13.1% overall. More women than men had osteoarthritis and rheumatoid arthritis, and the number of people with osteoarthritis increased with age. In this study, of those with osteoarthritis, 13.5% were men and 88% were women of those with rheumatoid arthritis, 19.3% were men and 56.3% were women. The number of patients with osteoarthritis increased with age, and rheumatoid arthritis was more common in older people. Subjects with osteoarthritis had lower grip strength than those without the disease, and the older the age at which rheumatoid arthritis was first diagnosed, the lower the grip strength. Conclusion: Grip strength is lower in patients with osteoarthritis than in those without osteoarthritis, and it is possible to estimate the degree to which muscle strength decreases.
