Objectives: This study investigated health behavior and nutritional status according to the presence or absence of periodontal disease using data from the Sixth National Health Nutrition Survey. Methods: Data from the 2013-2015 National Health Nutrition Survey were analyzed by frequency analysis, chi-square test, and Pearson's correlation analysis using SPSS 21.0. Results: Periodontal disease was more frequent in the group of patients who perceived that their subjective health status was "very bad" or were underweight according to the BMI classification. In men, periodontal disease occurred more frequently in those who were taking calcium (p<0.05), and periodontal disease occurred more frequently in the age group of 20-39, regardless of sex (p<0.05). In women, periodontal disease was less frequent in the group taking vitamin A. In both men and women, the presence of periodontal disease correlated with high fasting blood sugar and glycated hemoglobin levels. Conclusions: A customized program should be developed for each patient to identify factors that affect the relationship among periodontal disease, nutrient intake, and blood parameters. Such information will help improve the oral health of the population.

BACKGROUND/OBJECTIVES: The objective of this study was to assess the level of awareness, comfort, and likelihood of liberalizing the hemodialysis diet in practicing renal registered dietitian nutritionists (RDN). SUBJECTS/METHODS: An original, cross-sectional survey was sent to the Academy of Nutrition and Dietetics' Renal Practice Group in May 2017, consisting primarily of renal dietitians. RESULTS: A total of 187 renal dietitians responded to the survey designed to assess their current practices regarding the renal diet for hemodialysis patients and how comfortable they would be liberalizing the current restrictions. On average, 16.3% of dietitians are extremely likely to liberalize the restrictions on various food groups including fruits and vegetables, beans and legumes, and whole grains. CONCLUSIONS: RDN feel confident in their ability to interpret and apply evidence-based literature into practice, and they are moderately comfortable liberalizing the renal diet. The participants were generally more comfortable liberalizing the phosphorus restriction than the potassium restriction, and the sodium restriction remains important to control interdialytic weight gain and hypertension. Future research is needed to establish efficacy of a liberalized diet as well as interventions to help RDN feel more comfortable implementing a liberalization of the renal diet.

BACKGROUND/OBJECTIVES: The association between nutritional status and health-related quality of life (HRQoL) among patients with type 2 diabetes mellitus (T2DM) is not fully understood. This study was conducted to understand the role of nutritional status on HRQoL among people with and without T2DM. SUBJECTS/METHODS: Structured survey and direct measurement of anthropometric data were conducted among people with and without T2DM. Nutritional status was measured with Mini Nutritional Assessment tool and HRQoL was measured with a 36-item Short Form Healthy Survey. Data collection was conducted in Chuncheon, South Korea with 756 participants who are older than 40 yrs of age. RESULTS: This study found that overall HRQoL were significantly lower in people with T2DM than people without T2DM after controlling for key covariates. When stratified by nutritional status, a greater degree of negative impact of T2DM on overall physical HRQoL was observed among well-nourished or at risk of malnutrition, whereas significant and more evident negative impact of diabetes on overall psychological HRQoL was observed only among malnourished. CONCLUSIONS: The study results suggest the role of nutritional status among people with T2DM on overall, especially psychological aspects of HRQoL. Future longitudinal or intervention studies are warranted to test the impact of nutritional status on HRQoL among people with T2DM.

In this research, we examined the shifts in determinants influencing the frequency of eco-friendly food purchases pre- and post-COVID-19. Our analysis utilized filtered 2019-2021 Consumption Behavior Survey data from the Korea Rural Economic Institute Food, excluding any irrational responses. Given the nature of the dependent variable, a multinomial logistic regression model was employed with demographic factors, variables pertaining to food consumption behavior, and variables concerning food consumption awareness as predictors. Following the onset of the COVID-19 pandemic, an individual's level of education was observed to positively influence the frequency of eco-friendly food purchases. In contrast, income level and fluctuations in food consumption expenditure did not appear to have a discernible impact on the purchasing frequency of such eco-friendly products. Irrespective of the advent of COVID-19, variables such as the frequency of online food purchases, the utilization of early morning delivery services, dining out frequency, and the intake of health-functional foods consistently demonstrated a positive correlation with the propensity to purchase eco-friendly foods. Overall, consumers prioritizing safety, quality, and nutrition over price, taste, and convenience in their procurement decisions for rice, vegetables, meat, and processed foods exhibit an increased inclination toward the acquisition of eco-friendly food products.

This study was conducted to select representative agricultural products (4 types of fruits and 4 types of wild vegetables) in Chungju, define their sensual characteristics, derive suitable flavour-pairing and recipes for each ingredient, and use them as a cornerstone in the development of menus. For the experiment, 10 experts were selected to choose 8 representative agricultural products in Chungju, and 18 menus were selected through a flavour-pairing survey. A consumer panel (a total of 413 people, 105 in their 20s, 103 in their 30s, 103 in their 40s, and 102 in their 50s) for evaluating the characteristics of consumer preferences was selected. After the flavour-pairing survey 'sweet taste', 'light flavour', 'soft flavour', 'savoury flavour', 'familiar flavour', 'harmonious flavour', 'softness', and 'harmoniousness with food ingredients' were determined as drivers of liking, on the other hand, 'disturbance with food ingredients' and 'soybean fishy smell' were determined as drivers of disliking. The degree of consumer preference and overall acceptance were found to be related to the consumers' familiarity, suggesting that if a menu should be developed using unfamiliar local agricultural products, it should be configured with familiar recipes and seasoning methods.

Objectives: This study was conducted to analyze the factors related to unmet dental care needs in Korean adults who needed dental treatment. Methods: This study analyzed data from the 7th Korea National Health and Nutrition Examination Survey (2016-2018). Among the adults who participated in the National Health and Nutrition Examination Survey, 2,723 dental treatment who performed oral examinations were the final subjects. General characteristics and oral health characteristics were analyzed with complex sample chi-square test using the IBM SPSS program. Factors related to unmet dental care were analyzed by multiple logistic regression analysis. Results: As for unmet dental care needs related factors, bad oral health was 3.383 times higher, and usually was 1.736 times higher. In the use of dental clinic unmet dental care needs was 0.121 times lower. Unmet dental care needs was high, 1.366 times for those with the experience of tooth pain and 2.736 times for those with chewing difficulty. Conclusions: Based on the above results, it can be seen that oral health status or oral discomfort is related to unmet dental care needs. It is necessary to set goals to improve unmet dental care, recognize that one's oral health condition is very important, and continuously educate about oral health for each life cycle.

Hypertension is among the most common and important risk factors for stroke, heart attack, and heart failure which is considered to be the leading cause of death in Korea. The prevalence rate of hypertension in Korea is 27.9%, according to the 2006 Korea National Health and Nutrition Survey. Since non-pharmacologic nutrition education is recommended as the first step in the management of hypertension, evaluation of nutrition program is needed to form strategies for improving patients' dietary adherence. This study was designed to evaluate the overall effectiveness of a hypertension nutrition education program (HNEP) for reducing the salt intake, at a public health center located in Gyunggi-province. The HNEP was offered for 16 weeks from May to September in 2007. Nutrition education activities included cooking classes, food preparation demonstrations, physical fitness programs, salty taste preference test sessions, games, case-study presentations, planning and evaluation of menus, etc. Forty patients participated fully in the program which had 47 female enrollees. Data about nutrient intake (24-hour recall), nutrition knowledge, food behavior were collected before (baseline) and after the program. Changes after program completion indicated the following: 1) diastolic blood pressure was decreased (p < 0.05), 2) sodium (salt) intake was also decreased (p < 0.01), especially baseline high salt intake group, 3) nutrition knowledge was improved (p<0.001), 4) dietary behaviors for maintaining a low salt diet was improved (p < 0.001), 5) participants preferred cooking class from nutrition education methods. As a conclusion, it appears that a nutrition education program for hypertensive female elderly for reducing the salt intake might effectively decrease blood pressure and salt intake. It also improves nutrition knowledge, dietary behavior, and finally adherence to a recommendable low-sodium diet.

The purpose of this study was to investigate dietary behaviors and nutritional knowledge among immigrant women in multicultural families. In addition, this study reveals a necessity for nutrition education, which is apparent to both immigrant women living in multicultural families as well as nutrition education experts. The survey was conducted with 30 immigrant women within multicultural families in Seoul. The dietary behaviors of the women were significantly different by their period of residence. The longer they had resided in Korea, the higher their dietary behavior score. However, there was no significant difference in nutrition knowledge by their period of residence. This study also conducted in-depth personal interviews with 8 immigrant women who lived in Seoul, and with 4 nutrition education experts. These interviews were performed to provide profound insights regarding the content and means of nutrition education for immigrant women. Nutrition education for immigrant women living in multicultural families should proceed at a basic level in terms of language and content, using bilingual (Korean and their native language) education materials. Education topics and content need to be developed differently according to the level of Korean comprehension and period of residence in Korea. Also, this multicultural approach should be adapted when planning nutrition education since immigrant women have various acculturation levels, and the content and means of education should be adjusted to these acculturation levels. Management after nutrition education is necessary for immigrant women who do not have sufficient understanding of the Korean language. Practical educational methods such as real cooking practices and food purchasing simulations must be developed. Finally, the results suggest that the government needs to establish a systematic plan for nutrition education among immigrant women living in multicultural families. Policy support such as training nutrition educators on multicultural individuals residing in Korea is necessary for active and effective nutritional education.
