Purpose: This descriptive survey-based study aimed to identify the factors associated with obese adults' quality of life (QOL) using a secondary analysis of data collected through the 8th Korea National Health and Nutrition Examination Survey (2019). Methods: In this study, factors affecting the health-related quality of life of obese adults were analyzed by categorizing them into three independent variables: general characteristics, health behaviors, and mental health characteristics. Using t-test and analysis of variance (ANOVA), an analysis was performed to determine the differences in obese adults' QOL depending on their general characteristics, health behaviors, and mental health conditions. A hierarchical regression analysis was performed to identify the factors that affect obese adults' QOL. Results: In obese adults' general characteristics, the risk factors for QOL were older age, male, lower-income level, presence of spouse, and occupation. With regard to health behaviors, the risk factors were lack of exercise. In terms of mental health conditions, the risk factors were stress and suicidal ideation. Conclusion: Obese adults' QOL was affected by age, sex, income level, absence/presence of a spouse, occupation, health behaviors (e.g., exercise), and mental health conditions (e.g., stress and suicidal ideation).

The purpose of this study is to identify the main factors influencing breast cancer self-examination, a preventive health behavior, thereby increasing self-examination compliance for early detection of the disease. The data on which this study was based were collected from a survey of 601 ladies, aged 20∼59 years and residing in Seoul, employing such mehtods as X²-test, ANOVA, t-test, F-test, Person's Correlation Coefficient and Stepwise Multiple Regression. The resulting conclusions are as follows; 1. Discrepancies in self-examination compliance rate are found in accordance with the differences of general characters of the surveyed persons. For instance, those who are well educated and better off are better compliers than those who are not (p<0.001), and those around whom breast cancer patients are better ones than who are not (p<0.01). 2. Self-examination compliers have higher health belief than non-compliers. Compliers have more knowledge in health and have higher susceptibility, barriers and health concern (p<0.001), and higher benefits (p<0.01), and higher seriousness (p<0.05) than non-compliers. 3. Whereas those who have loftier health belief show higher compliance rate (p<0.001), seriousness turned out to have no correlationship with self-examination compliance. 4. Stepwise Multiple Regression portray that following factors influence self-examination compliance in arder named. (1) barriers (2) susceptibility, (3) health concern, (4) age, (5) benefits, (6) education level. Even so, it turned out that these factors alone can explain only 20％ of self-examination compliance. Therefore study for the other factors ought to be continued. I submit following suggestions ending this study. 1. Since breast cancer self-examination is an essential health behavior needed for early detection of the disease, efficient and proper health education program eyed for regular and periodic self-examination is required to be developed, thus reducing the deaths and pains caused by the disease. 2. Proper policies of the government for the prevention of breast cancer is strongly urged to be formed in concrete manner. 3. Continuous study of the other factors affecting self-examination compliance must be carried on.

Objectives: This study aimed to examine the actual use of interdental care products (ICPs), such as dental floss (DF) and interdental brushes (IDB), among Korean youth, confirm their relevance to periodontal health, and determine the factors that influence the use of each product. Methods: This study included 15,912 young adults aged 19-39 years and data from the Korea National Health and Nutrition Examination Survey (KNHANES) (2007-2018). The usage rate of ICPs according to the characteristics of the subjects for each cycle of KNHANES was presented. Multivariable logistic regression analysis was performed to identify factors affecting the use of ICP. Results: The use rates of DF and IDB gradually increased until the 7th period, reaching 34.8% and 26.8%, respectively. The rate of using more than one ICP also showed a tendency to gradually increase from 25.2% in the 4th period to 50.0% in the 7th period. The use of interdental care products is related to gingivitis and periodontitis. Factors related to the use of ICP were gender, age, education level, frequency of brushing, and dental examination experience. Conclusions: The use of dental floss or interdental toothbrushes was related to periodontal health, but only half of the adults aged 19-39 years used ICP. Therefore, oral health experts should actively encourage the use of DF and IDB in young adults.

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.

Objectives: This study purports to comparatively study health condition, health behaviors, and health care utilization of Koreans living in Korea and in the US, and then, to analyze the factors influencing them. Methods: The collected data were analyzed on the basis of the 2005 Korea National Health and Nutrition Examination Survey. Of 25,196 adults aged 19 or older, 7,802 respondents to health behavior survey and 5,526 respondents to physical examination survey. The analyzed data of the Korean Americans were the results of the California Health Interview Survey (CHIS) conducted by the UCLA Center for Health Policy Research in 2005. This study analyzed the responses of 645 known Korean respondents to the 2005 CHIS. Results: In regard to differences in overall health condition between the two groups, it was found that both the male and female Korean Americans thought their own overall health conditions were relatively poor compared to Koreans, especially in relation to diabetes and cardiovascular diseases. For smoking status considered as one of health behavior factors, smokers of the Koreans account for 46.1% which is higher than that of the Korean Americans and the proportion of the Koreans smoking daily is also at least two times higher than that of the Korean Americans. Similarly, for alcohol drinking, the Koreans showed higher drinking experience rate and no less than three times higher drinking frequency than that of Korean Americans. Conclusion: It is expected that this study will contribute greatly to solving health problems among foreign immigrants and overseas Koreans in future by clarifying any differences in health status and health behaviors resulting from sociocultural differences despite of similar genetic factors.
