Flavonoids are phytochemicals that occur ubiquitously in plant foods that have been reported to have potential roles in the prevention of cancer, inhibition of platelet aggregation or inflammation. However, there was no accurate data reported on the intake of middle-aged Korean population. The present study was designed to assess dietary intake of flavonoids (including isoflavones) of 304 adults (20-59 yr, male 115, famale 189) living in Daejeon area using semi-quantitative food frequency questionnaire. The questionnaire consisted of 50 food items, including vegetables, soy products, seaweeds, nuts and beans, fruits and beverages. Our self-administered questionnaire contained questions regarding subject's habitual diet and alcohol intake over the previous 3 months. Average daily intake of individual flavonols such as quercetin, kaempferol, myricetin, and flavones such as luteolin, apigenin was 15.7, 8.7, 0.21, 2.07, 0.03 mg/day, respectively. Daily intake of daidzein and genistein, which are the commonly found isoflavones in soy products, were 16.6 and 21.4 mg/day, respectively. Combined intake of flavonoids was 64.3 mg/day. No effect of smoking, drinking and exercise was observed on flavonoids consumption. Food items that has the highest daily intake of each compounds were; quercetin (onion, 9.49 mg/day), kaempferol (strawberry, 1.18 mg/day), myricetin (green tea, 0.81 mg/day), apigenin (lettuce, 0.03 mg/day), luteolin (onion, 0.05 mg/day), daidzein (soybean sprout, 5.99 mg/day), genistein (soybean sprout, 7.02 mg/day). These findings provide valuable information on understanding the dietary flavonoids intake from a typical Korean daily diet, which might help to identify the risks for developing various diseases.

In recent years a concern of excessive intakes of vitamins and minerals from various sources is increasing, since there has been a marked increase in production and consumption of vitamin and mineral supplements and fortified foods. The purpose of this study was to assess the maximum exposure of vitamins and minerals from various sources including diet, fortified foods, and health functional foods among Koreans. As a result, the highest exposure group of most vitamins and minerals from diet was adults (30 - 49 years of age) according to 2001 Korean National Nutrition and Health Survey Report. Maximum dietary intakes of vitamin A, $B_1,\;B_2$, C, nicotinamide, calcium, phosphorus and iron were 0.5 - 7 times of the RDA for Koreans, 7th ed. Maximum intakes of vitamins and minerals from fortified foods by adults (20 - 59 years of age) were 8 - 760% of the Korean RDA. In addition, maximum exposure of vitamins and minerals from vitamin mineral health functional foods by middle aged people was 35 - 140% of the upper limits (UL: DRI for Koreans). As a consequence, maximum combined intakes of vitamin $B_6$, vitamin C, calcium, iron and zinc from the above sources including diet, fortified foods and vitamin mineral health functional foods were greater than the UL. These results would be applied for determining the safe upper limits of vitamin and mineral of health functional foods.

Body mass index(BMI) is recognized as one of the most useful indexes for adiposity in children and adults. This study was conducted to provide information on BMI distribution by age and sex in Korean children, and to identify sociodemographic factors that affected BMI among children. The study was conducted on 2376 children(boys 1184, girls 1192) living in a middle-size city in Korea. Subjects were selected from the primary schoolchildren in grades 1-6 using the two-stage sampling method. Their mean age was 9.4 years. The percentile of BMI tended to increase as age increased in both sexes. The 85th percentile for boys, aged 6-12 years, was 19.8kg/㎡, and the 95th percentile was 22.5kg/㎡. The 85th percentile for girls, aged 6-12 years, was 18.9kg/㎡, and the 95th percentile was 21.5kg/㎡. Multiple regression analysis was carried out to predict BMI from percent ideal body weight (PIBW), age and sex. After adjusting PIBW and age, BMI for boys was 0.062kg/㎡ lower than that for girls. One year of age increased BIM by 0.55kg/㎡. The prevalence rate of overweight and obesity based on PIBW was 15.8% and 15.0% for boys, and 14.0% and 11.0% for girls, respectively. Demographic factors such as sex, age, and parents' obesity influenced children's BMI. After adjusting for sex, age and parents' BMI, the presence of another children in family, and mother's employment status showed a strong effect on children's BMI. The results suggest an age-sex specific BMI distribution of Korean children. The present study also provides direct evidence of a correlation between early life environmental factors, such as presence of siblings or mother's employment, and BMI level in Korean children.

Objectives: The purpose of this study was to identify basic health needs of adult clients to develop a community nursing center model in Seoul. Methods: Data were collected using a questionnaire survey from 894 adults registered at a public health center who were health management members, and visiting 4 community nursing centers, University of Wisconsin, Milwaukee during the period from July 1999 to January 2000. The data were analyzed using frequency, percentile, t-test, and ANOVA. Results: 1) The University of Wisconsin- Milwaukee School of Nursing has a long tradition of developing 4 community nursing centers with innovative health care programs. CNCs integrate the ability to implement and test effective intervention strategies with education, research, and practices of nursing students and faculty. They were designed to enhance the health status and quality of life for urban communities through the development of productive, outcome focused, collaborative partnerships among UWM-Nursing faculties and staff, other health and human service providers, consumers, and policy makers. It links the financial resources between UWM and 9 voluntary agencies and 12 public funding organizations including federal. state, and local governments. 2) Of the total health management members, 37.4% were reported to have at least one type of chronic disease such as hypertension, diabetes, and arthritis. Ten percent of them reported having obesity, and 44.2% reported lack of exercise. The health status of the subjects was within normal range in laboratory tests. However, female subjects showed more significant differences in obesity and cholesterol levels than male subjects. The subjects, who were in their 50s, showed more significant differences in obesity, SGOT, SGPT, and cholesterol levels than the subjects in other age groups. Conclusion: A community nursing center needs to be developed, that has a link between the nursing college and the public health center, with partnerships and a multidisciplinary approach. Based on the study results, exercise programs for middle aged adults are considered necessary. In particular, specific exercise programs for pre-menopausal women needs to be implemented in the future to prevent them from developing osteoporosis.

Objectives: This study aimed to examined the socioeconomic disparities in oral health related behaviors and to assess if those behaviors eliminate socioeconomic disparities in oral health in a nationally representative sample of adults aged 30-64. Methods: Data are from the Korea Third National Health and Nutrition Examination Survey (2005). Behaviors were indicated by smoking, over intake of daily calories from carbohydrate, perceived stress, frequency of daily tooth brushing, use of oral hygiene goods, insufficient oral treatment. Oral health outcomes were self-reported dental caries and periodontitis during the last 12 months and perceived oral health. Education, household income, and employed status indicated socioeconomic position. Sex, age, residential area, marital status were adjusted for in the logistic regression analysis. Logistic regression analysis was used to assess socioeconomic disparities in behaviors. Logistic regression model adjusting and not adjusting for behaviors were compared to assess the change in socioeconomic disparities in oral health. Results: Clear socioeconomic disparities in all behaviors were showed. After adjusting for behaviors, the association between oral health and socioeconomic indicators attenuated but did not disappear. For example, the odd ratios of reporting poorer oral health for persons in no education or elementary school education and middle school education groups, compared with college or higher education group, were 1.77 (95% CI: 1.36-2.29) and 1.56 (1.19-1.97), respectively. After adjusting for all indicators of behaviors, these odds ratios attenuated to 1.54 (1.17-2.03) and 1.48 (1.15-1.91) for those groups, respectively. Conclusion: These findings suggest that the presence of more complex determinants of socioeconomic disparities in oral health should be considered with developing preventive policies for those disparities.

As an indicator of skin health, acidified skin surface pH ranging from 5 to 7 is crucial for maintaining skin barrier. In this study, we evaluated the relationship between skin pH and dietary pattern (DP) as well as nutrient or food intake in 48 healthy middle aged adults. Skin pH was measured in the skin surface of the inner arm, and blood lipid profile was analyzed. Dietary intake data were obtained using 1 day 24 hour recall method, and DP was extracted using factor analysis. Results revealed that skin pH ranged from 5.15 to 6.88 in all subjects. There was no significant difference in skin pH between males and females. When subjects were grouped by tertile of skin pH, the food intake of fruit, and the nutrient intake of omega 6 fatty acid, potassium, vitamin A, vitamin C, ${\beta}$-carotene, and riboflavin in the first tertile group with skin pH ranging from 5.15 to 5.68 were significantly higher than in the third tertile group with skin pH ranging from 6.26 to 6.88. There was no difference in blood lipid profile between the first and the third tertile group. Among 5 DP extracted by factor analysis, DP5 characterized by a high intake of nuts and fruits as well as a low intake of beverages and alcohol was inversely correlated with skin pH after adjusting for gender and age. DP5 was positively correlated with nutrient intake of carbohydrate, fiber, potassium, iron, vitamin A, vitamin C, ${\beta}$-carotene, thiamine, and riboflavin but negatively correlated with sodium after adjusting for gender, age, smoking, and energy intake. Therefore, acidified skin pH could be maintained by these DP and nutrients.

Objectives: To examine the sex-specific factors associated with being unaware of one's hepatitis B virus surface antigen (HBsAg) seropositivity status in a large, HBsAg-positive population of Koreans. Methods: In total, 1197 subjects aged 19 years or older who were HBsAg-positive according to data from the 2007-2012 Korea National Health and Nutrition Examination Survey were included. Subjects were considered unaware of their HBsAg seropositivity status if they answered that they had no knowledge of being previously infected by the hepatitis B virus (HBV) or diagnosed with HBV hepatitis. Multivariate Poisson regression models with robust variance estimate were used to assess the significance of the variables using weighted frequencies. Results: The majority (77.8%) of HbsAg-positive Korean adults (females, 81.9%; males, 74.6%) were unaware of their HBsAg seropositivity status. We found that sex (female: prevalence ratio [PR] 1.19), household income (low: PR, 1.15), marital status (never married: PR, 1.18), self-rated health (moderate: PR, 1.14; good: PR, 1.12), and alcohol use (at least 2-3 times/wk: PR, 1.21) were associated with being unaware. In females, age (50 to 59 years: PR, 1.29; ${\geq}70$ years: PR, 1.30), household income (low: PR, 1.37; middle-low: PR, 1.24), and marital status (never married: PR, 1.33) were associated with being unaware. In males, self-rated health (moderate: PR, 1.14; good: PR, 1.21) and alcohol use (at least 2-3 times/wk: PR, 1.21) were associated with being unaware. Conclusions: Factors related to the socioeconomic status of females and the health-related behaviors of males were found to be associated with being unaware of one's HBsAg seropositivity status.

Objectives: This study was conducted to investigate the status of total sugar intake and contributing foods in Korea according to age groups. Methods: This study used 24-hour dietary recall data from the 8th Korea National Health and Nutrition Examination Survey (2019-2021) to investigate the nutritional and total sugar intake status among Koreans. A total of 18,338 research participants (≥3 years old) were included in this study. To analyze the types of foods contributing to total sugar intake, these foods were categorized into 15 types. Moreover, we examined the total sugar intake and ranked the most consumed foods by age groups (3-11 years, 12-18 years, 19-34 years, 35-49 years, 50-64 years, over 65 years). A survey procedure was employed for statistical analysis. Results: The energy intake ratio from total sugars was approximately 12%-15%, which was within the recommended range. However, the proportion of individuals consuming total sugar exceeding 20% of their total caloric intake is nearly 20%, raising concerns about excessive sugar consumption. Furthermore, the percentage of participants whose intake of sugar from processed foods exceeded 10% of their total calories was highest in the 12-18 age group at 37.1%, followed by the 3-11 age group at 35.2%, and the 19-34 age group at 34.0%. Carbonated drinks, cola, and cider were the primary foods consumed by children and adolescents (3-18 years old) and young adults (19-34 years old). For middle-aged and older adults, mixed coffee with sugar and cream was a prominent contributor to sugar intake. Conclusions: This study investigated sugar consumption patterns among Koreans, finding the principal foods contributing to this intake. Identifying these contributors is pivotal, given their potential impact on public health.

Objectives : To estimate the awareness, treatment and control rate, as well as to identify the awareness-related factors for hypertension. Methods : The study participants were 482 adults (men 206, women 276), aged 45 or over, diagnosed with hypertension and living in Chuncheon. The awareness rate was defined as the proportion of persons among those with hypertension who had previously been diagnosed by a physician. The treatment rate was defined as the proportion of persons who had used anti-hypertensive medication, among those who were aware of their hypertension. The control rate was defined as the proportion of persons who kept blood pressure normal, among those who had been treated for their hypertension. Multivariable logistic regression analysis was carried out for the awareness-related factors using SAS VER 8.1. Results : The awareness, treatment, and control rate were 55,8% (53.4% for men; 57.6% for women), 89.6% (87,2% for men; 91.2% for women), and 34.4% (28.1 % for men; 38.6% for women), respectively. The awareness-related factors included a family history of hypertension (odds ratio[OR], 5.63; 95% confidence interval[95% CI]=1.53-20.72), smoking([Ex; OR 0.38, 95% CI= 0.15-0.96)], [Current; OR 0.28, 95% CI=0.10-0.80]), and alcohol intake ([Ex; OR 3.22, 95% CI 1.03-10.09],[Current; OR 3.36, 95% CI=1.30-8.71]) for men, and education(OR 2.23, 95% CI=1.10-4.53), body mass index(OR 2.72, 95% CI=1.13-6.53), and self-rated health(OR 2.38, 95% CI=1.07-5.30) for women. Conclusions : The awareness rate of hypertension among the middle aged and elderly in Chuncheon was 55.8%. The related factors of awareness were gender specific. Further studies are needed to elucidate the putative reasons for these gender differences.
