Purpose: The aim of this study was to examine the association of food security with the total and individual flavonoid intakes among Korean adults. Methods: Study subjects were 13,454 men and 19,563 women aged 19 years and older who participated in the 2007~2012 Korea National Health and Nutrition Examination Survey. Subjects were classified into food-secure and food-insecure groups using the answers to a self-reported question on food sufficiency of subjects' household. The total and individual flavonoid intakes were calculated by linking 24-h dietary recall data of subjects with a flavonoid database. Mean differences in dietary outcomes by food security status, and major food sources of total flavonoids were examined. Results: In this cross-sectional study, 5.8% of male adults and 6.6% of female adults were in food insecure households. Mean daily intakes of total flavonoids, flavonols, flavones, flavanones, flavan-3-ols, isoflavones, and proanthocyanidins were significantly lower in food-insecure groups than food-secure groups among both male and female adults. The differences were maintained in total flavonoids, flavones, flavanones, and flavan-3-ols after adjusting for total energy intake. Mean intakes of fruits and vegetables were significantly lower in food-insecure groups and the total flavonoid intake from fruits and vegetables was also significantly lower in food-insecure groups. The major food sources of total flavonoids were apples (20.7%), mandarines (12.0%), and tofu (11.5%) in the food-secure group, and apples (14.9%), tofu (13.3%), and mandarines (12.6%) in the food-insecure group. Conclusion: This study showed that food insecurity was associated with lower intakes of flavonoids and reduced intakes of fruits and vegetables in a representative Korean population.

Objective : This study used the data of the National Statistical Office to analyze the time use of disabled youth and their self-satisfaction with it by their type of occupation. Methods : Using raw data extracted from Statistics Korea, 84 disabled youth from 10 to 24 years old were re-classified into six occupational areas based on Occupational Therapy Practice Framework (OTPF)-3. The occupational types were classified according to the time use by individuals based on data from Statistics Korea. Finally, according to the type of occupation, self-satisfaction with the use of time was identified. Results : The total amount of time spent by disabled youths was the largest in the rest and sleep categories, followed by daily living, education, leisure, social participation, and play. The analysis of occupational types showed that the groups were turned around (10.71% of participants), high activity group (50.00%), low activity (28.57%), and balanced (10.71%). There were significant differences between types in the first five of the aforementioned categories. There was no significant difference in the lack of time use, but there was a significant difference among their satisfaction with their use of time. The balanced type (21.53%) reported the most satisfaction. inadequacy Conclusion : The purpose of the project was to provide the raw data of intervention activities that can improve the quality of life and health of disabled youth. By analyzing their time use and occupations, deficiencies in time management and their satisfaction with their use of time can be noted.

The purpose of this study was to identify the prevalence of urinary incontinence of community residing climacteric women, and to identify the relationship between urinary incontinence and quality of life. The subjects of this study were 156 women(45 to 59 years old). Data was collected from Sep. 1 to Dec. 1 2002 by an interview or self-reporting by a structured questionnaire. The questionnaire was composed of items of general characteristics, urinary characteristics, and conditions of urinary incontinence, using the modified Henderickson's stress incontinence scale(1981), and the quality of life scale developed by RO, You Ja(1988). The data was analyzed by the SPSS/WIN program using descriptive statistics, Pearson correlation coefficients, t-test and AVOVA. The results of the study were as follows : 1. The prevalence of urinary incontinence was 76.3%. Of the incontinent women, 42.0% had experienced urinary incontinence for a period of one to three years. Frequency of urinary incontinence was once or twice per day for 42.9% of the urinary incontinent women. Most of the participation with urinary incontinence(91.6%) had mild leakage of urine. In the whole urinary incontinent women, 70.6% had never treated or managed their urinary incontinence. Most of the subjects(79.8%) were mildly incontinent, and the prevalence of moderate and severe urinary incontinence was 20.2%. The mean scores among the items of urinary incontinence, in descending order, were increase of abdominal pressure($1.45{\pm}1.05$), coughing($1.16{\pm}0.93$), and sneezing($1.03{\pm}0.92$). 2. The average score in the level in the quality of life variables was 3.12. The urinary incontinence and quality of life were correlated negatively(r=-0.103, p<0.001). 3. There were statistically significant differences in the score of climacteric woman's self reported quality of life according to : amount of urinary incontinence(F=12.68, P=0.001), duration of urinary incontinence(F=6.97, P=0.009), number of urinary incontinence(F=4.77, P=0.03), existence of urinary incontinence(t=148, P=0.05). In conclusion, this study was a preliminary study to provide nursing practice guidelines for climacteric woman with urinary incontinence. Nurses working with climacteric woman should develop and provide adequate care for the incontinent climacteric subjects. In future research, it is recommended to identify comprehensive factors related to urinary incontinence, including the effective management of urinary incontinence.

The purpose of this study was to investigate the dietary habits, the nutritional knowledge and the consumption patterns of convenience foods of 618 university students located in the Gwangju area, from November twentieth to November thirtieth, 2002. The subjects included 301 males (48.7%) and 317 females (51.3%). This survey was conducted using a self-administered questionnaire. The percentage of students who were underweight, normal and overweight based on their body mass index (BMI) was 3.7, 88.0 and 8.3 far the males, and 29, 71 and 0 for the females, respectively. Most students (73.8%) skipped breakfast. This was because of lack of time (65.1%) of the cases. Self-reported eating habit problems were eating irregular meal (52.4%), overeating (21%), prejudiced meal (12.4%) and skipping meal (7.4%). The type of favorite snack was biscuit (31.9%) and cup Ramyon (31.9%). The rates of alcohol drinking in male and female students were 88.0% and 85.8% respectively, and the rates of smoking were 35.9% and 28% respectively. Males ate fiequently cup Ramyon (2.08 $\pm$ 2.95), fries (pork cutlet, fried potato) (1.91 $\pm$ 2.58), Ramyon (1.81 $\pm$ 3.00) and kimbab (1.70 $\pm$ 3.17) more frequently, while females ate kimbab (2.25 $\pm$ 3.26), cup Ramyon (1.89 $\pm$ 2.09), fries (pork cutlet, fried potato) (1.77 $\pm$ 2.67), Ramyon (1.46 $\pm$ 1.1.95) and fish paste (1.45 $\pm$ 2.22) more frequently. The nutritional knowledge score was higher in females than in males. The mean consumption patterns of convenience foods of students living in home were lower than that of students living in dormitory and boarding w/cooking. When the amount of pocket money available and the body mass index increased and the nutritional knowledge level was low, the mean consumption of convenience foods increased. The mean consumption of convenience foods correlated negatively with nutritional knowledge (p < 0.01). Therefore, nutritional education for university students is needed so as to improve their health and nutritional education program should be developed to meet the various needs of these students.

There is little evidence on the effects of environmental tobacco smoke (ETS) on prevalence of periodontal disease. The aims of this study were to explore the trends of prevalence of periodontal disease and types of exposure to smoke, including ETS according to the survey year, identify factors affecting periodontal disease, and compare the effect size of periodontal disease between active smokers and secondhand smokers. Data on 11,643 individuals were obtained from the fourth and fifth Korean National Health and Nutritional Examination Surveys. Information on exposure to ETS at home and work was self-reported. Severity of periodontal disease was evaluated using the community periodontal index. A multivariate logistic regression analysis was performed to model periodontal disease using types of smoking and the survey year. Overall, the prevalence of periodontal disease was 26.0% (n=3,029) and about 9% of the study population were secondhand smokers. The prevalence of periodontal disease among smokers was significantly increased according to smoking types by year. Active smokers showed a statistically significant adjusted odds ratio (aOR) for having periodontal disease except in the year 2007, whereas secondhand smokers had significant associations only in 2010 (aOR, 1.68; 95% confidence interval, 1.05 to 2.70) compared to non-smokers. For secondhand smokers, the statistical relationship of predicting periodontal disease was weaker than that of active smokers. However, ETS should separately be considered as an important risk factor for periodontal disease. This study suggested the need for further investigation of the impact of ETS on prevalence of periodontal disease using in-depth research designs and objective measurements for assessing periodontal disease and ETS.

Young black men(YBM) have the most severs levels of high blood pressure(HBP) and, in all reports but one, the lowest of HBP control of any age /sex /race group. To increase entry into care, remaining in care, and BP control for young(18-49 years) Black men, It is needed to review socio-demographic, medical characteristics, and behaviors(importance of and difficulty with HBP control behaviors, or worry about mdication) for experimental intervention study(educational- behavior strategies) of hypertensive urban young black men. The 204 participants had an average age of 38.8+7.0 years and an average educational level of $11.0{\pm}2.4$ years; only 23.1% were employed full- or part-time while 26% were on disability ; and 6% were married. Only 35.3% had an MD for HBP care and 37.3% had some form of health insurance. The average BP of those men currently being in care on medication(35.3%) was $148.2/95.1{\pm}19.5/11.3$ compared to those men not taking HBP care $153.7/99.1{\pm}14.0/9.8(p<.05)$. The average creatinine level was 1.3(excluding 3 marked elevations of 15.9, 9.6, and 7.7) for the 163 men consenting to have their blood drawn. Self-reported co-morbidity induded heart disease 7.8%, diabetes 8.9%, high cholesterol 18.2%, CVA 3.4%, alcohol and drug related problems 27.9% and 22.5% respectively. The kidney disease of those men currently being in care & on medication was 9.7 compared to those men not taking HBP care 0.8(p<.05). The problems of with sex life, physicl activity and dearly thinking of those men currently being in care & on medication was higher compared to those men not taking HBP care(p<.05). Questions of 'during the past month, on how many days did you have 5 or more drinks (bottles) of any alcoholic beverag?' and smoking of those men currently being in care & on medication was 18.1% and 72.2% compared to those men not taking HBP care 27.3 and 82.6%, respectively. HBP control behaviors was assessed with 1-5 point Likert subscales(5=extreme, 1-none at all), In general, th men reportd low levels of perceived psychological barrier to HBP care and control behaviors; importance of and difficulty with HBP control behaviors, or worry about mdication. For example, on a five point scale(1=none at all, 5=extreme), average ratings for perceived important and difficulty with BP care and behaviors were 2.8(SD=1.2) and 2.5(SD=1.1). Average ratings for perceived benefit with BP care and behaviors worry about medication of those men currently being in care on medication was 4.0(SD=0.9) and 2.2(SD=1.1) compared to those men not taking HBP care 3.6(SD=0.8), 2.8 (SD=1.6) respectively(p<.05). These data support the need for educational-behavioral strategies of community health nurse to improve high blood pressure control in this high risk group through perceived barriers to treatment, health care skills and use of resources, and social support.

This paper measures welfare losses from beef consumption reduction, which might be resulted from psychological anxiety about potential outbreak of BSE (commonly known as "bad cow dieses") risks after announcement of resuming US-beef imports in April of 2008. Unlike the previous literature of utilizing the contingent valuation method or experimental market approach, this study estimated quality-differentiated consumer demand functions using the information of self-reported beef consumption quantity, individually constructed price indices of beef, and subjective perception of BSE risks. The empirical results based on a survey sample of 360 residents in Jeon Ju city were consistent with the anticipation from economic theory, in terms of coefficients of own prices, substitute prices and income variables. The announcement of resuming US-beef imports did not make significant differences in the sign and sizes of the main economic variables. However, the subjective perception variable about BSE risks had negative significant impacts on beef demand functions after the announcement but not significant before the announcement. The welfare losses in a form of equivalent variation (EV) corresponding to the increases in concerns about BSE risks were measured to be about 30 thousand won per household.

The population aged 95 years and older in Seoul approximately increased to five-fold over the past 10 years, while nationwide rates increased to three-fold. In order to examine the dietary habit and nutritional status of oldest-old population living in Seoul, we recruited 87 subjects (25 males and 62 females) aged 95 years and older. The prevalence of underweight (BMI < 18.5 $kg/m^2$) and obesity (BMI ${\geq}25kg/m^2$) were 18.2% and 18.2% in males, and 20.8% and 9.4% in females, respectively. In self-assessment of health, only 25.3% answered to be unhealthy. More males exercised regularly and reported a wide range of activities than females. The average of %Kcal from carbohydrate, protein and fat (C : P : F) was 64.9 : 13.8 : 21.2 in males and 68.1 : 14.2 : 17.7 in females. The average daily energy intake was 1,307 kcal in males and 1,304 kcal in females. More than 75% of subjects were taking under estimated average requirements (EAR) for vitamin $B_1$, $B_2$ & C and Ca. The average of mean adequacy ratio (MAR) was 0.66 in males and 0.70 in females, and 28.8% of males and 12.9% of females were in MAR < 0.50. Based on MAR, 32.0% of males and 14.5% females were classified as normal and 16.0% of males and 25.8% of females were classified as malnourished. Our subjects were taking more animal food, especially milk and its products, compared to those living, in rural areas. However, a significant proportion did not meet the EAR for vitamin $B_1$, $B_2$ & C and Ca.

The purpose of the study is to investigate the women's college students' perceptions on work scope of dental hygienists and the inclusion of dental hygienists in the category of medical personnel. A self-reported questionnaire was completed by 180 Suwon women's college students from August 26, to September 11, 2019. The questionnaire consisted of oral health condition of the subjects, perception of both legal and illegal work scope of dental hygienist, the degree of recognition of medical personnel occupations by subject, and the reason why they thought dental hygienists are medical personnel. The collected data were analyzed based on frequency, percentage, and descriptive statistics using IBM SPSS VER 22.0. It showed significantly different perception of work scope of dental hygienists according to the major. Percent of 70 of the subjects perceived dental hygienist as a medical personnel, the opinions on the necessity were as follows: The Ministry of Health and Welfare issues a license through the national examination role and dental hygienists assist the care of dentist. Therefore, clinical dental hygienists should be promoted to medical personnel through the amendment of the medical law so that the duties practiced by the dental hygienist can be matched with the legal practice.
