This secondary analysis study used the 2015 Korea Health Panel data to identify the difference of factors affecting the quality of life (QoL) of Korean adults with diabetes mellitus (DM). The data from 1,343 subjects who met the criteria for screening was analyzed by multiple linear regression and quantile regression analyses. As a result, the average QoL of the subjects was .86 (±.14). The factors affecting the QoL of the subjects were age, gender, education level, spouse, economic activity, type of health insurance, and regular physical activity (all p<.05). However, there were differences of the results when dividing the subjects into three groups according to their QoL level. The factors for the lower 25% group were age, gender, education level, spouse, economic activity, type of health insurance, and regular physical activity, and those factors for the middle 50% group were age, gender, education level, spouse, type of health insurance, and regular physical activity, and those factors for the top 75% group were spouse, economic activity, household income, type of health insurance, and duration of DM. Based on these results, it is important to develop and provide a differentiated intervention strategy that considers the influential factors in order to improve the QoL of Korean adults with DM.

Aside from political leaders' popularity rates and the stock exchange index of business firms, ordinary people are highly interested in aspects of daily life, such as housing, income, health, family, food, human relations and work. Cross-national opinion polls on daily-life satisfaction were carried out in Japan, South Korea, Thailand, Hong Kong, Macao, the Philippines, India, Myanmar, Taiwan, China, Malaysia and Pakistan in the fall of 2013 and winter 2014. The percent difference index (PDI) is formulated as the sum of two positive responses (satisfied and somewhat satisfied) minus the sum of two negative responses (dissatisfied and somewhat dissatisfied). Percent difference indices are given according to society and daily-life aspects. For our analysis to go beneath national average and to go beyond national borders, two lines of analysis are carried out. First, the distance between the level of satisfaction of the top and bottom quartiles is given for each society and according to each of the daily-life aspects. Second, the regional sum of satisfaction of the top quartiles and bottom quartiles are shown crossed by daily-life aspects. In this article we confine ourselves to preliminary comparative description and analysis. More solid and deep comparisons will be carried out by local polling leaders of 12 Asian societies in the succeeding issue of the Asian Journal of Public Opinion Research. Nevertheless, two key threads stand out from this preliminary comparisons. First, social relations (family and human relations) stand out as most satisfied aspects of life in most of twelve societies. Second, the need to go beneath national averages and beyond national borders in analyzing cross-national surveys is confirmed. The comparability and validity of cross-national surveys with varying sampling method and survey mode are briefly discussed toward the end of the article.

BACKGROUND/OBJECTIVES: The aim of this study was to estimate average total fat and fatty acid intakes as well as identify major food sources using data from the Korea National Health and Nutrition Examination Survey (KNHANES) VI-1 (2013). SUBJECTS/METHODS: Total fat and fatty acid intakes were estimated using 24-hour dietary recall data on 7,048 participants aged ${\geq}3years$ from the KNHANES VI-1 (2013). Data included total fat, saturated fatty acid (SFA), monounsaturated fatty acid (MUFA), polyunsaturated fatty acid (PUFA), n-3 fatty acid (n-3 FA), and n-6 fatty acid (n-6 FA) levels. Population means and standard errors of the mean were weighted in order to produce national estimates and separated based on sex, age, income, as well as residential region. Major food sources of fat, SFA, MUFA, PUFA, n-3 FA, and n-6 FA were identified based on mean consumption amounts of fat and fatty acids in each food. RESULTS: The mean intake of total fat was 48.0 g while mean intakes of SFA, MUFA, PUFA, n-3 FA, and n-6 FA were 14.4 g, 15.3 g, 11.6 g, 1.6 g, and 10.1 g, respectively. Intakes of MUFA and SFA were each higher than that of PUFA in all age groups. Pork was the major source of total fat, SFA, and MUFA, and soybean oil was the major source of PUFA. Milk and pork were major sources of SFA in subjects aged 3-11 years and ${\geq}12years$, respectively. Perilla seed oil and soybean oil were main sources of n-3 FA in subjects aged ${\geq}50years$ and aged < 50 years, respectively. CONCLUSIONS: Estimation of mean fatty acid intakes of this study using nationally represented samples of the Korean population could be useful for developing and evaluating national nutritional policies.

Purpose: This study examined the association of fruit and vegetable consumption with asthma in Korean adults. Methods: Data on 16,528 adults aged 19-64 were collected from the Korea National Health and Nutrition Examination Survey (KNHANES). The general characteristics of the subjects, daily food intake, and daily energy and nutrients intake were investigated according to fruit and vegetable consumption. All statistical analyses were conducted based on SAS software version 9.4. Results: The prevalence of doctor-diagnosed asthma was 2.6%, and ranged between 1.8% and 3.1% depending on fruit and vegetable consumption. As fruit and vegetable consumption increased, the individuals showed a higher average age and household income, but a lower educational level, smoking rate, and frequency of alcohol consumption. The group with higher fruit and vegetable consumption had higher intakes of all food groups without milk and dairy products and energy and nutrients than the counterpart group. For the intake rate of energy, the group with higher consumption of fruit and vegetables had a higher intake rate of carbohydrate and protein and a lower intake rate of fat. The risk rate of asthma with the third quartile group regarding fruit and vegetable consumption was 35%-40% lower than that of the first quartile group. Conclusion: The results suggest that adequate consumption of fruit and vegetable will help to improve the risk of asthma. Moreover, prospective cohort studies and clinical test research are necessary to measure the effects of fruit and vegetable consumption on the occurrence of asthma.

This study was conducted to investigate variables related to dietary fiber intake among sixth grade children in an elementary school in Daejon city. One hundred and forty-seven children completed a questionnaire for determining their socioeconomic background and their food habits. Anthropometric measurements were taken, and a 24-hour diet recall method was used to collect three-day food intakes. The socioeconomic status of the children's families belonged to the upper middle class; 53.0% of their fathers and 25.8% of their mothers had completed college or higher degrees. 27.9% of the mothers had jobs, including part-time jobs. Approximately 30% of the children skipped breakfast, 66.4% of the children preferred animal foods to plant foods, and 52.4% of the children preferred green vegetables to yellow or pale vegetables. Grilled meat dishes, such as Grilled beef rib with seasoning, Bulgogi, grilled pork belly and beef steaks, were the most popular types of food eaten outside home by the children. Daily dietary fiber intake was 14.5 g in boys and 14.5 g in girls, and these intakes are low compared to the standard guidelines. The average intakes of energy and protein of the children were 84.5% and 114.0% of the Korean Recommended Dietary Allowances (RDAs), respectively. Besides energy, riboflavin, iron and calcium intakes were below the RDAs, and especially calcium intake was only 50% of the RDAs. On the other hand, thiamin, niacin, ascorbic acid, protein and phosphorus intakes exceeded the Korean RDAs. Family income or the children's body mass index (BMI) was not directly related to dietary fiber intakes. However, higher dietary fiber intakes tended to be related to higher intakes of green vegetables and fruits. Children with higher dietary fiber intake tended to prefer plant foods to animal foods. Energy and most nutrients, except heme iron and retinol, showed positive relationships with dietary fiber intake. Especially potassium and plant origin protein and calcium were highly correlated with dietary fiber intakes(r＞0.6). From these results, it is concluded that dietary fiber intakes of these sixth grade elementary school children were less than the standard reference and it is anticipated to decrease further in the future with increased incomes. Therefore, increased intakes of dietary fiber by elementary school children should be promoted through nutrition education, together with the development of cooking methods and recipes utilizing green vegetables and fruits.

This study aims to understand the relationship between the awareness of oral health prevention and general characteristics by investigating the awareness of oral health prevention and to provide basic data to make oral health education guidelines for oral health prevention and the need for oral health prevention by analyzing factors that influence the awareness of oral health prevention. For about a month since December 2016, the data of 380 people aged 10 and over residing in Seoul and the Gyeonggi Province was gathered, and the following results have been obtained after excluding 19 people whose answers were insufficient. It was found that gender (female, p<0.05), age (50 years and over, p<0.05), educational background (high school diploma and university diploma or higher, p<0.05), average monthly income (KRW 3.0 million - 4.0 million, p<0.05), oral health importance (p<0.001), and awareness of the need for oral health prevention (p<0,001) among the selected independent variables had statistically significant effects on the awareness of oral health prevention. Considering the results above, I believe that it is important to develop oral health education programs, which reflect the characteristics of people in order to motivate them to perform prevention activities, rather than education programs about simply acquiring knowledge for prevention activities and to establish social conditions that can enable continued education, in order to increase the awareness of oral health prevention activities.

This study divided people into the age groups of their twenties, thirties, forties and more than fifties and multilaterally examined their nutritional knowledge and mode and attitude of food intake in order to survey the effects that the level of concern with nutritional knowledge according to age has on the mode of food life with a sample of women in more than their twenties who live in the region of Seoul. If I examine the general characteristics of those who are surveyed, in age their twenties accounted for the most part of 34.6 percent, and in educational background people who did not graduate from high schools accounted for 58.6 percent and jobless people 55.9 percent and there were many people whose standard of living was thought to be in a middle level, and in the income of home, people with less than two million Won were universal, and in physical condition an average case accounted for 37.8 percent, but the case that most of people were fat(49.1%) was characterized by more than a thin case(13.1%,). In the object of survey the case of being nutritionally reeducated was as 76.1% higher than the case of not doing so, but the necessity for nutritional education was not felt by 62.7%, and statistical significance was indicated according to age (p<.001***) and in the sources of nutritional knowledge mass media accounted for 49.3%. The knowledge about nutrition was well known as a whole and in evaluating nutritional knowledge, top group accounted for 75.4% and evaluating scores according to age showed differences, but had no statistical significance. As a result of surveying the actual condition of food intake and food habit, those who are surveyed was surveyed to observe the quantity of a meal (31.9%) best, and they were revealed in the order of 30.5%, of taking in fruits and 28.3%, of having meals regularly. In particular, in the regularity of meals, statistical significance according to age(P<.001***) was indicated by their fifties accounting for 38.7% and their twenties 10.9%. In food habit, regardless of age, the case of taking in marine algae for 0 to two days indicated 53.7% and the case of faking in greeny yellow vegetables 52.0%, and we could see that modern people evade the kind of vegetables, and in the scores of evaluating food habit a middle group accounted for 57.3% and as age increases, the group of higher age showed more desirable mode of food life than the one of lower age, showing statistical significance(p<.01**).

Recent improvements in the standard of living, national income and medical care, and a decline in the infant death rate which have occurred related to economic growth and modernization, have led to a longer average life-span and a higher ratio of elderly people in the total population, Therefore, not only in the field of nursing science, but also in the field of many other discipline, issues concerning the elderly have been given increasing interest. A great deal of effort has been spent on increasing the quality of life for elderly people. This study was conducted to analyze the correlation between social support and quality of life. The sample consisted of III subjects residing at home and 107 subjects residing in institutions all of whom were over 65 years of age. The data collection period was from October 23, 1990 to January 26, 1991. Social support was measured using the Norbeck social Support Questionnaire developed by Norbeck, translated by Oh, Ka Sil and quality of life was measured using the QOL scale developed by No, You Ja. Data were analyzed using pereentages, t-test, Pearson Correlation Coefficient and ANOVA. The results of this study are as follows : 1. There was a statistically signifivant difference in the level of social support between the two groups (t＝-8.83, p＜.001), The elderly at home reported a much higher level of social support. 2. There was a statistically significant difference in the level of QOL between the two groups (t＝-5.77, p＜.001) . The elderly at home reported a much more positive quality of life. 3. There was a positive correlation between social support and QOL for the elderly at home ard it was statistically significant (r＝.32, p＜.001). 4. There was a postitive collealtion between social support and QOL for the elderly in institutions and it was also statistically significant (r＝.19, p＜.05). 5. The relationship between the general characteristics of the elderly at home and the variables of social support and of QOL were as follows ; 1) according to sex(t＝10.57, p＜.01) and the number of offspring(F＝6.19, p＜.01), there was a statistically significant difference in social support. 2) according to amount of Pocket money, there was a statistically significant difference in QOL(F＝2.98, p＜.05). 6. The relationship between the general characteristics of the elderly in institutions and the two variables were as follows ; 1) according to sex(t＝6.24, p＜.05), the number of offspring(F＝6.16, p＜.001) and religion (F＝2.58, p＜.05), there was a statistically significant difference in social support. 2) according to religion, there was a statistically significant difference in QOL(F＝2.90, p＜.05). In conclusion, it can be said that social support is an important variable related to QOL in the elderly and that social support levels are higher for the elderly residing at home. Therefore, more specific and objective approaches and efforts are needed to effectively use resources to maintain the elderly at home and to enhance social support available to the elderly in institutions and thereby increase QOL regardless of residence.

The purpose of this study was to investigate the influence of the factors such as self-esteem, social supports, socio-economic status of parents, degree of disability in child, stress coping, religion, and sports.exercise on the qualities of lives in mothers with disabled children. Data were collect from 45 institutions(schools from kindergarten to senior-high, special education institutes, and social welfare institutions) by self-report questionnaire, and the subjects of the study were 386 mothers in Seoul whose children were attending the schools or institutions. Findings according to socio-demographic variables are as follows: 1. Mothers with disabled children in this study thought their quality of life as average degree. 2. The younger the mothers and children, the higher the quality of life was. 3. The higher the educational level and monthly income, the higher the quality of life was. 4. There was no statistically significant difference between the existence and nonexistence of spouse, and between the existence and nonexistence of religion as well. Findings analyzed by multiple regression are as follows: 1. Among 7 independent variables 'self-esteem'(${\beta}$=.49, p<.001), 'social supports'(${\beta}$=.15, p<.01), and 'socio-economic status'(${\beta}$=.11, p<.05) were found to be statistically significant in quality of life in mothers, while the rests were found not significant. 2. 'Self-esteem' was found to be the most influencing variable, meaning that the psychological factor such as self-esteem is more important than environmental factors in qualities of lives in mothers. 3. The total amount of explanation of the model was Adjusted R square=.301, so that it can be said about 30% can be explained among total variance of the qualities of lives in mothers with disabled children. Conclusions and recommendations based on the results above are: First, it is strongly recommended to conduct programs promoting self-esteem in mothers with disabled children, and to include 'self-esteem' hereafter in the studies related to qualities of lives in mothers with disabled children. Second, comprehensive and practical countermeasures should to be formulated to back up expenses for education and medical care, purchasing relative tools and equipments, plus helping to find jobs.

This study was designed to investigate the mar factors affecting selection of delivery facilities by pregnant women. Five hundred women hospitalized at 23 Seoul-area delivery facilities, such as university hospitals, general hospitals, hospitals, and clinics were selected and given questionnaires from April 24 to May 7, 1990. A total of 350 questionnaires were collected and analysed for the study. The results are as follows ; 1. In general, variables which significantly affected the choice of delivery facilities included the age of women, their educational level, the educational level of their husbands, monthly average incomes and residential areas. 2. In analyzing the obstetrical characteristics of the women, those variables significantly affecting the choice of delivery facilities were the gestational period, the facilities for prenatal care, the frequency of prenatal care, the type of delivery, the frequency of miscarriage, previous delivery experiences and the awareness on prenatal care. 3. In comparing the motivation factors for selecting the delivery facilities, all the factors except convenience and need for hospitalization differed significantly among delivery facilities. 4. The factor analysis was assessed for twenty possible factors motivating the choice of delivery facilities. Six factors including personal service, scale of the facility, reputation, urgency, convenience, and experience were noted explaining by 57.7%. 5. In the discriminant analysis used to clarify the major factors affecting the selection of delivery facilities, the 16 significant variables were regarded as independent variables, and the type of delivery facilities was considered a dependent variable. The stepwise method was applied to the analysis. Detected discriminant variables were the facilities for prenatal care, scale factor, personal service factor, urgency factor, convenience factor, reputation factor, experience factor, gestational period, types of delivery, frequency of miscarriage, age and income. These 12 discriminant variables were tested, with reference to discriminant prediction, on their importance in the choice of the delivery facility, by the discriminant functional formula. The test showed a hit-rate of 67.7%. The results suggest that general characteristics, obstetrical characteristics, and motivations for selecting the delivery facilities differ significantly according to the types of the delivery facilities. This study implies that all types of delivery facilities should attempt to acommodate characteristics and motivations of pregnant women. The facilities should be prepared to increase their patients satisfaction with required medical conditions by improving service and responding to the pregnant women's preferences.
