  • This study was conducted to develop a Han-sik database as well as to assess the effects of Han-sik on dietary quality among Koreans. The Han-sik database was developed by a focus group composed of food and nutrition specialists considering the results of Han-sik perception surveys conducted in previous studies for frequently consumed dishes. Among the 1,322 dish items identified in the $4^{th}$ (2007-2009) Korea National Health and Nutrition Examination Survey (KNHANES), 973 items (73.6%) were classified as Han-sik. Han-sik usage was defined as the percentage of Han-sik items of all individually consumed dish items in the dietary data of 22,113 subjects who participated in a 24-hour diet recall in the $4^{th}$ (2007-2009) KNHANES. Dietary quality was evaluated based on adherence to the Korean Food Guidance System (KFGS), which was calculated as the percentage of the number of servings consumed in each food group out of recommended servings according to age and sex. Mean usage of Han-sik was 80.1% and was higher in older age groups, rural areas, as well as in households at the lowest income level. Han-sik usage was also higher on weekdays as well as for breakfast. Adherence to the KFGS was significantly higher for grains, meat fish egg beans, vegetables, and fruits (p<0.001) but lower for milk dairy products and oils fats sugars (p<0.001) across the quartiles of Han-sik usage. The results of this study indicate that Han-sik usage is high among Koreans. Further studies are needed to update the Han-sik database as well as investigate the association between health-related factors and Han-sik use.

  • Dental sealant is a procedure to prevent dental caries on the occlusal surface of healthy teeth. Raw data from the 6th-7th Korean National Health and Nutritional Examination Survey (KNHANES) were analyzed. This study was conducted to provide basic data which is necessary for the national health care project and for expanding the standards of coverage for the Dental sealant procedure. In this study, subjects were a total of 4,366 children from the age of 6 to 18 and surveyed for the Amount of Received Dental sealant and rate of Received Dental sealant. In 2012, the coverage rate for pit and fissure sealing procedures differed significantly in terms of age, residential area and average monthly income. This coverage varied as per average monthly income in 2014 and as per age and average monthly income in 2017 (P < 0.05). In 2014, average monthly income had a significant influence on the coverage rate, while age and average monthly income had a significant influence on it in 2017 (P < 0.05). These findings suggest that in order to increase the sealing procedure coverage, continuous promotion of dental sealant projects, reduction of copayments, inclusion of varied tooth types and age groups, expansion of coverage to isolated areas and inclusion of socially disadvantaged groups are necessary.

  • Purpose: This study aims to compare and analyze the changes in the physical and mental health status of middle-aged women before and after menopause and their quality of life over the past 10 years. Methods: A descriptive study was conducted by using secondary data from the 4th and 7th Korea National Health and Nutrition Examination Survey (KNHANES) involving middle-aged women in menopause (N=8,363). Data were analyzed using the complex sample x2 test. Results: Compared to 10 years ago, notable changes were observed in general characteristics. These included increase in age, education level, economic activity, and urban residency. In addition, there was an increase in alcohol consumption, a decrease in smoking, and a decline in regular exercise. The study also observed changes in obesity rates and an increase in dyslipidemia and stress levels, along with positive changes across all aspects of quality of life. Conclusion: The results indicate temporal changes in general characteristics, major physical and mental health factors, and the quality of life of middle-aged women in menopause. Thus, it is essential to consider these changes when designing health interventions such as health promotions and education initiatives for middle-aged women experiencing menopause. Further research is necessary for identifying factors influencing the quality of life of middle-aged women in menopause.

  • This study was conducted to evaluate the association between periodontal disease and diabetes mellitus. The final analysis population of this study was composed of 4,830 adults with diabetes mellitus or periodontal disease and aged 19 years or older, based on the third-edition data of the 4th Korea National Health and Nutrition Examination Survey (KNHANES) (in 2009). Diabetic status and potential confounders were used in questionnaire materials and physical examination materials, and the presence of periodontal disease was used in the materials for oral health examination by a dentist. For diabetic status, fasting plasma glucose (FPG) levels <100 mg/dl were subcategorized into normal group and FPG levels ${\geq}100mg/dl$ into impaired fasting glucose group; glycosylated hemoglobin (HbA1c) levels <7% into normal group and HbA1c ${\geq}7%$ into diabetes group, on the basis of the American Diabetes Association. According to the 2009 Korea Health Statistics, the case where the pocket depth is 3 mm or more was defined as periodontal disease. The association between the two diseases was evaluated through $x^2$-test and logistic regression analysis using R-commander 2.14. In impaired fasting glucose group, community periodontal index (CPI) groups 3 to 4 had higher risks for periodontal disease 1.23 times (95% confidence interval, 1.07~1.42) than those of CPI groups CPI 0~2, even after adjustment for several confounders. In addition, periodontal disease and diabetes mellitus showed statistically significant differences depending on age, sex, income level, educational background, smoking status, alcohol consumption, and snack intake. The analyses of the third-edition data of the 4th KNHANES showed that there was a statistically significant association between periodontal disease and diabetes mellitus as examined by means of CPI in this study.

  • The objective of this study is to analyze the characteristics of persons with a high sugar-intake ratio (%E) and factors affecting sugar-intake ratio with the Korea National Health and Nutrition Examination Survey ($6^{th}$ KNHANES). The sugar-intake ratio is the calories of sugar from processed food divided by the daily total intake of calories. In this research we used two statistical methods, the cluster analysis and one-way analysis of variance (ANOVA). Cluster analysis was used to classify groups of sugar-intake ratios. For analysis of factors affecting the sugar-intake ratio, we applied the ANOVA. Korean have about a 3.89% sugar-intake ratio from processed food per day. The demographic characteristics of people with higher sugar-intake ratios were found to be more women than men, younger men with less education, more people in the household, smaller height, weight waistline and body mass index (BMI). Also office worker, lower drinking frequency, not getting a hypertension, diabetes, hyperlipidemia, lower breakfast and dinnner frequency, not experiencing nutritional education, and not using nutritional labeling. For reducing intake sugar in what are called health-hazardable nutrients in the food sanitation act, it is necessary to educate the people with high sugar ratio who were identified in this study.

  • Objectives: The purpose of the study is to investigate the degree of disparity in unmet dental care needs in Korean adults. Methods: Using data from the 5th Korea National Health and Nutrition Examination Survey, 9,573 adults between 25-54 years old were selected. The reason for unmet dental care needs was analyzed by chi square test and logistic regression analysis. Results: Those having unmet oral health care needs accounted for 41.3%. The majority of the reason (1,036 persons) was "busy with school or work" and the second reason was financial burden (1,028 persons). Those who were female individuals (OR: 1.14, CI: 1.02-1.27), having higher income (OR: 0.85, CI: 0.72-0.99), and perceiving poor oral health status (OR: 5.68, CI: 4.64-6.95). Conclusions: It is necessary to extend and implement the nationwide public assistance of dental care services among the second-to-the bottom and low income people.

  • We used data from the 7th Korea National Health and Nutrition Examination Survey (KNHANES) (2016~2018) to investigate an association between high sensitivity C-reactive protein (hsCRP) and uric acid in the obese. Obesity was defined as a body mass index (BMI) of 25 kg/m2 or more, severe obesity as a BMI of 30 kg/m2 or more, and morbid obesity as a BMI of 35 kg/m2 or more. In the complex samples multiple logistic regression, despite adjustment by adding major risk factors, the odds ratio (OR) for obesity was higher in the group with high levels of both, hsCRP and uric acid than the reference group at all stages (obesity, OR 1.89, P<0.001 vs. severe obesity, OR 5.04, P<0.001 vs. morbid obesity, OR 8.20, P<0.001). The association between hsCRP and uric acid in obese patients increased from 1.89 to 8.20 as the obesity level increased, suggesting that participants with increased BMI were significantly affected by hsCRP and uric acid. Moreover, the interaction between hsCRP and uric acid was statistically significant even in the model corrected for major confounding factors (P for interaction=0.009).

  • Purposes: The purpose of this study, was to identify similar factors between reasons for unscreening and unmet health care needs through prior research, and based on this, we wanted to figure out the relevance between the medical screening and unmet health care needs. Methodology: The analysis was conducted using data from 9,640 adults aged 19 or older who don't have a missing value from 16,277 participants in the 7th, 1st&2nd Year (2016&2017) of the National Health and Nutrition Examination Survey (KNHANES). Unmet health care needs were investigated as a self-reported questionnaire of whether medical service was required but not received. And the analysis was performed through the Chi-Square Test and Multi-logistic Regression analysis. Findings: As a result of the analysis, unmet healthcare needs were higher who received only one type of screening comparative to who screened both. and were highest who screened neither. Practical Implications: Unmet health care needs are the center of a vicious cycle, such as morbidity and mortality, which is detrimental to the quality of life, and continues to increase. Therefore, it is necessary to find ways of realizing health care that guarantees the health rights of all citizens by policy guarantee and support for the subjects to recognize the importance of thorough education of screenings rather than only health screening or cancer screening.
