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.

This study is to investigate the eating habits of 420 businessmen living in urban areas (Taegu, Gumi, Youngchon and Changwon) in Kyungbuk and Kyungnam provinces. This survey was carried out by questionnaires. The results are summarized as the following in the association of demographic variables and eating habits, occupation (p<0.001), age (p<0.01), spouse's occupation, dwelling state, and monthly income (p<0.05) had statistically significant relationships. Middle aged adults placed more attention on eating habits than young adults. High-class professionals, managers and salesmen had a high frequency of 'good' eating habits, while office-workers had a high frequency of 'bad' eating habits. In the association of eating behavior, health status variables and eating habits, the frequency of meals, exercise, sleep, degree of fatigue, life styles, digestibility, and health status (p<0.001) had significant relationships. It seems that eating behavior and health conditions have direct effects on eating habits.

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.

The objective of this study was to investigate the influence age-friendly environment factors on different age groups' life satisfaction. Data were taken from "2014 Survey on the Aged Society", with total of 1,000 participants divided into three groups: 300 youth participants from age 20 to 44, 300 middle aged participants from age 45 to 64, and older adults participants from age 65 and more. Performing ANOVA and multiple regression analysis showed that age-friendly environment factors had positive correlations with life satisfaction, regardless of the participants'age. However, the sub-dimensions of age-friendly environment that affected each age group was different. Among three sub-dimensions of age-friendly environment, which were housing factor, social participation factor, and community and health service factor, only housing factor affected life satisfaction of the youth group, while both community and health service factor, and housing factor affected life satisfaction of the middle-aged and the elderly groups. The result clearly presents that age-friendly environment factors are not only beneficial for older people but for people at all ages. Therefore, various measures need to be taken in order to increase the age-friendliness of communities, and improve the quality of life.

Purpose: The purpose of this study was to explore the sexual life and sexual life satisfaction of elderly people. Method: The participants were 181 elders over 65 years of age. Data were collected from February 10 to December 15, 2007 by interviews and questionnaires. Results: Of the respondents 17.1% still had sex in their lives but sexual satisfaction was less than that of middle-aged adults. Further, 31.8% of the elders reported no experience of sex over the past 10-19 years. The reasons for not having sex were 'no sexual partner' or 'no sexual desire'. Finally, 27.2% wanted to have a date. The main reason for dating was to relieve loneliness and the reason for not dating was 'good as it is', 'having date is shameful'. The level of satisfaction with sexual life was 2.71. Satisfaction with sexual life was higher for elders who had a spouse and for elders who still had sex. Conclusion: This study provides bases on the usefulness of various nursing intervention programs to enhance the quality of life through better understanding of the sexual life and sexual life satisfaction of elders.

Purpose: The purpose of this study was to compare metabolic syndrome (MS) risk factor prevalence by obesity and age in middle-aged women. Method: Two hundred and fifty-one subjects were recruited from the health promotion center of a tertiary care hospital in an urban city. MS was defined by the third report of the national cholesterol education program (NCEP) expert panel on detection, evaluation, and treatment of high blood cholesterol in adults(Adult Treatment Panel III)(ATP III), and obesity was determined by body mass $index(BMI){\geq}25kg/m^2$. Results: The mean blood pressure, fasting glucose, total cholesterol, and triglyceride were significantly higher in the obese group than in the non-obese group. The prevalence of MS, hypertension, and impaired fasting glucose were significantly higher in the obese group than in the non-obese group. In the forties, blood pressure was significantly higher in the obese group than in the non-obese group. In the fifties, body fat, systolic blood pressure, fasting glucose, total cholesterol, and triglyceride were significantly higher in the obese group than in the non-obese group. Conclusions: These results show that the nurse should focus on the obese fifty year old female patients for improvement of the MS risk factors.

As the rural economy is worsening day by day due to rapidly declined population and increase of aging generation, the emptiness in the rural areas are becoming increasingly intensifying. In particular, urban runoff of young adults and middle-aged people and the decrease in birth rate have shrunk the rural population reaching to raise concerns on the stage of emptiness. On the other hand, people in the urban areas with rapid industrialization and overcrowding call for the variety of housing needs moving away from monolithic housing types. In order to solve problems of rural communities such as emptied out rural society as well as the problems of urban communities in overcrowdings, environment, and housing, it is required to develop an urban-countryside village complex pursuing advantages of the rural environment and convenience of urban living. Of this time, there needs a change in rural development policies which can make the urban residents migrate and settle in the rural areas as they are naturally embracing the rural life according to the social background and demand.

The purpose of this study is to analyze the contents of the questionnaires used in dietary surveys and to evaluate each item in relation to the item construction strategy. Articles of which the contents were related to food, nutrition, diet, dietary behavior, and related areas. Published from 1997 to 1999 were searched fir and a total of 121 questionnaires were collected and analyzed. The questions in the questionnaires were classified into related areas and sub-areas. Among the keywords in the title of the articles, the term 'nutritional status'(or 'dietary intake status') was most frequently used. The terms such as dietary status, obesity, health, food habit, and dietary behavior were also frequency used. Major topics of the items in the questionnaires varied according to the life cycle of the subjects of the study. The topics most frequently asked in each lift cycle were as follows : overeating, snack, and food preference for preschool- and school-aged children ; anthropometry, weight control, and snack for middle and highschool students : meal skipping, smoking, and drinking for college students : disease, smoking, drinking, and exercise for adults : and smoking, drinking, disease and perceived health for the elderly. Inappropriate questions with complicated language, typographic and grammatic errors, unnecessary words, and negative questions were found. Therefore, care should be taken to construct each question so as to avoid possible misinterpretation. Also, a standardized questionnaire be developed for survey researchers.

Although estrogen is known to playa role in fatty acid metabolism, it remains unclear whether fatty acid oxidation in mature female rats differs from fatty acid oxidation in peri-pubertal young rats. In this study, we measured fatty acid metabolism in the skeletal muscles and livers of 5 and 50 weeks old male and female rats. The rate of palmitate oxidation in the liver and gastrocnemius red in the 50-week-old female rats were elevated as compared to the 5-week-old females, whereas there were no differences in the male rats. The rate of palmitate oxidation in the gastrocnemius red was correlated inversely with intra-abdominal fat mass in the 5-week-old male and female rats, whereas the palmitate oxidation rate was positively correlated with fat mass in the liver and gastrocnemius red in the 50-week-old rats. HOMA-IR and plasma insulin levels were positively correlated with intra-abdominal fat mass in the pooled 50-week-old male and female rats, but this correlation was not apparent in 5-week-old rats. In summary, the rate of fatty acid oxidation measured in the middle-aged adult female rats was significantly higher than those measured in the peri-pubertal young female rats. This difference may be attributed to the influence of ovarian hormones.
