Objectives: Based on the 7th National Health and Nutrition Examination Survey 1,135 adults aged 19 years were selected as the final study subjects to investigate the relationship between oral health and chewing difficulty in adults. Methods: Frequency analysis, chi-square test, and logistic regression analysis were performed for general characteristics, oral health behaviors, awareness symptoms, and oral health using SPSS Program 21.0. Results: Regarding factors related to chewing difficulty, the oral health was 0.44 times lower than the average level and 0.28 times lower than the good condition. In the case of oral examination, chewing difficulty was 0.85 times lower. The speaking problem was 0.11 times lower in usually than inconvenient and 0.06 times lower in not inconvenient. In the case of un-treatment, it was 0.40 times lower than that in the case of treatment. The chewing difficulty was significantly higher by 2.09 times in the case of experience of tooth pain and 1.36 times in the case of periodontal disease. Conclusions: Based on the above results, it is thought that prevention and treatment are actively needed to identify factors of oral health to improve oral health, to solve chewing difficulty and to improve chewing function.

Objectives : The objective of this study was to investigate the relationship between the status and necessity of dental prosthesis and mastication function in the Korean elderly. Methods : This study investigated 4,557 elderly people aged over 65 in the 5th Korea National Health and Nutrition Examination Survey(2010-2012). Frequency analysis, ${\chi}^2$ test, and logistic regression analysis were used. Results : Those aged over 75 complained of greater discomfort in mastication function than those from 65 to 74, and it was statistically significant(p<0.001). Mastication discomfort was not so significant in those with higher education and higher income(p<0.001). Those who did not use prosthesis tended to have better mastication function(p<0.001). Denture users complained of mastication discomfort when they used it(p<0.001). Conclusions : This study verified the relationship between the discomfort in mastication and related factors, and will provide the basic data for the access to dental clinic services.

Objectives: We investigated whether the rate of depressive symptom is higher among family members of asthmatic patient compared to people who had no asthmatic family member. Methods: This study used data from the fourth and fifth Korea National Health and Nutrition Examination Survey (2007-2012). In this cross-sectional study, 15,987 men (mean age 46.4) and 20,906 women (mean age 47.4) were included. To compare the rate of depressive symptoms in individuals who had a family member with asthma and those who did not have, we analyzed data using survey logistic regression. Results: Diagnosed depression was reported by 3.0% of the study population, by 4.2% of asthmatic patient's family member, and by 3.0% of individuals who did not have a family member with asthma. Family members of asthmatic patient increased odds of diagnosed depression compared with those who did not had an asthmatic family member (odds ratio = 1.56, p = 0.008). Conclusions: To prevent depression among family members of asthmatic patient, health education for entire family of asthmatic patient need to be considered. Also, government and policy makers should give more attention to caregivers who had a family member with asthma.

Objectives: Environmental, social and personal factors influence eating patterns. This study aimed to investigate the relationship between unhealthy food outlets within a residential area and obesity using nationally representative Korean survey data and data from the Census on Establishments. Methods: Data on the food intakes and socioeconomic variables of a total of 9,978 adults aged ${\geq}19$ years were obtained from the 2013-2014 Korea National Health and Nutrition Examination Survey. Geographic locations of restaurants were obtained from the 2013 Census on Establishments in Korea. Administrative area was categorized into tertiles of count of unhealthy food outlets based on the distribution of number of unhealthy food outlets among all urban (Dong) and rural (Eup or Myun) administrative districts in Korea. Multilevel logistic regressions model were used to assess the association between the number of unhealthy food outlets and obesity. Results: People living in the district with the highest count of unhealthy food outlets had higher intakes of fat (45.8 vs. 44.4 g/day), sodium (4,142.6 vs. 3,949.8 mg/day), and vitamin A (753.7 vs. $631.6 {\mu}gRE/day$) compared to those living in the district with the lowest count of unhealthy food outlets. A higher count of unhealthy food outlets was positively associated with frequent consumption of instant noodles, pizza, hamburgers and sandwiches, sweets and sour pork or pork cutlets, fried chicken, snacks, and cookies. Higher exposure to unhealthy food outlets was associated with increased odds of obesity (1st vs. 3rd tertile; OR 1.689; 95% CI 1.098-2.599). Conclusions: A high count of unhealthy food outlets within a residential area is positively associated with the prevalence of obesity in Korea. The results suggest that food environmental factors affects the health outcomes and interventions aiming to restrict the availability of unhealthy food outlets in local neighborhoods may be a useful obesity prevention strategy.

Objectives: This study aimed to assess the relationship between electric toothbrush use and the presence of community periodontal index (CPI) code calculus among Korean adults. Methods: Data from the 7th Korea National Health and Nutrition Examination Survey were analyzed. Multiple logistic regression analysis with a complex sampling design was conducted, adjusting for general characteristic factors. Analyses were performed using SPSS Statistics 29.0. Results: Among the participants, the prevalence of electric toothbrush users was 5.3%. Within this group, 4.7% had periodontal disease, whereas 5.9% did not (p=0.025). Even after adjusting for general characteristics factors in model II of electric toothbrush use, the odds ratio remained statistically significant at 0.791 (95% CI: 0.631-0.992) in all cases. Conclusions: Electric toothbrush use appears to be associated with potential benefits in managing the CPI code calculus distribution; however, evidence supporting this notion remains insufficient. The study findings suggest that these results could be a basis for future studies related to oral hygiene products and the design of oral health promotion programs.

Purpose: The aim of the study was to assess the prevalence of preschooler obesity/overweight and to identify associated factors. Methods: This study was a cross-sectional study. Data for 591 preschoolers, 432 fathers and 538 mothers from the Korea National Health and Nutrition Examination Survey 2013-2014 were included. Obesity/overweight was defined by 2007 Korean National Growth Charts. T-test, Rao-Scott ${\chi}^2$, multivariate logistic regression was used for the analysis. Results: Prevalence rates for preschooler obesity/overweight were 14.9% (obesity, 5.4%; overweight, 9.5%). The preschoolers with atopic dermatitis or allergic rhinitis or asthma (OR=2.78, 95% CI [1.27-6.09], p=.011) and eating more thiamine per day (OR=1.01, 95% CI [1.00-1.02], p=.001) showed higher obesity/overweight development. The only parental factor affecting preschooler obesity/overweight was parental body mass index (father, OR=1.18, 95% CI [1.09-1.28], p<.001; mother, OR=1.09, 95% CI [1.04-1.15], p<.001). Conclusion: Interventions on preventing preschooler obesity should be introduced much earlier for children with risk factors. Results from this study can be used as preliminary data to develop effective strategies to prevent obesity in Korean preschoolers.

Family type is not only an important sociodemographic variable for health studies but also influences the health behavior and health condition of individuals. This study assessed a representative sample to see whether family type is associated with health behavior in Korean adults age 65 and older. This is a cross-sectional study of 9,535 Korean elderly who participated in the 2010-2012 Korean National Health and Nutrition Examination Survey. The subjects were classified as couple cohabitation, couple-offspring cohabitation, alone, or alone-offspring cohabitation. We assessed the relationship between family type and six health behaviors (smoking, high risk drinking, walking, oral examinations, health screenings, and influenza vaccinations) after controlling covariates. The "alone" classification had a significantly higher risk of no health screening, but was more likely to have an influenza vaccination than couples. Significant interactions between family type and healthy behavior were observed with oral health screening, influenza vaccination, and smoking {Odds ratio (95% confidence interval), 1.452 (1.066-1.980), 1.375 (1.083-1.747), 2.246 (1.604-3.146)}. There is a significant association between family type and healthy behaviors.

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.

Instant noodle is one of the most popular foods in Korea. The objective of this study was to examine the association of instant noodle consumption and food and nutrient intake among children and teenagers in Korea. We used dietary data from 24-h recall of 1,748 subjects aged 7-19 years who participated in the 2005 Korea National Health and Nutrition Examination Survey. Those who consumed instant noodle once or more during the survey period were categorized as "instant noodle consumer (INC)" and were compared for food and nutrient intakes with the others (non-INC). The average age of the INC was 13.4 and that of the non-INC was 12.4; girls consumed more instant noodles than boys (p < 0.05). There was no significant difference in BMI between the two groups. With the exception of grains, as compared to the non-INC, the INC consumed significantly less amounts of potatoes, vegetables, mush-rooms, fruits, spices, seafood, and milk and dairy products. With respect to nutrient intakes, the INC-group showed significantly higher nutrient intakes of energy, fat, carbohydrate, sodium, thiamine, and riboflavin; however, as compared to the non-INC-group, the INC-group showed significantly less intakes of calcium, niacin, and vitamin C. The overall result suggests that consuming instant noodles may lead to excessive intake of fat and sodium, but it may cause an increased intake of thiamine and riboflavin. Therefore, nutrition education that helps children and teenagers choose a balanced meal while consuming instant noodle should be carried out. In addition, manufactures of instant noodles should consider nutritional aspects in product development processes.
