This study aimed to determine the association between household types and healthy dietary practices among Korean adults. A cross-sectional analysis was performed using nationwide data on 23,488 participants from the 2017-2021 Korea National Health and Nutrition Examination Survey (KNHANES). Based on self-reported data, the participant household types were classified into single- and multi-person households. The adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for healthy dietary practices according to household types were calculated by applying multivariable logistic regression analysis after adjusting for confounders. Of total, 11.21% and 88.79% were single- and multi-person households, respectively. Compared with individuals living in multi-person households, those in single-person households had lower odds of adhering to healthy dietary practices (AOR: 0.88, 95% CI: 0.79-0.98) and consuming adequate saturated fatty acids (<7% of energy) (AOR: 0.78, 95% CI: 0.69-0.88). In addition, men and individuals aged ≥65 years living in single-person households exhibited lower odds of consuming adequate saturated fatty acids and ≥500 g of fruit and vegetables per day than those in multi-person households. Single-person households often find it a challenge to practice a healthy diet. Hence, nutritional policies and educational support that help individuals living alone consume healthier diets are warranted.

Purpose: This study was designed to construct and test structural equation modeling on healthy menopausal transition in middle-aged women in order to identify variables affecting healthy menopausal transition. Methods: Participants, 276 women, 45 to 60 years of age, with menopausal symptom score higher than 5 on the Korean version of Menopause Rating Scale, were recruited in three cities and one county of Gyeongnam Province. Research data were collected via questionnaires and analysed using SPSS version 18.0 and AMOS version 20.0. Results: After confirmatory factor analysis, one of the observed variables was excluded due to relatively low factor loading. The model fit indices for the hypothetical model were suitable for the recommended level: GFI=.93, CFI=.92, RMSEA=.05. Self-efficacy, self-differentiation, and menopausal symptoms explained 67.7% of variance in menopausal transition, and self-differentiation was the most influential factor for menopausal transition. Self efficacy and menopausal symptoms explained 9.6% of variance in menopausal management, although "menopausal symptoms" was not significant. Conclusion: These results suggest that nursing interventions to improve self-differentiation, self efficacy, menopausal management and decrease menopausal symptoms are critical for healthy menopausal transition in middle-aged women. Continued development of a variety of community-based nursing interventions to facilitate healthy menopausal transition is suggested.

The purpose of this paper is to estimate effects of healthy city policies on reducing social costs. The analyses were dune at the cities, counties, and communities levels in 2009, and covered Seoul Metropolitan Area(SMA). For estimation of reducing social costs, it developed a system dynamics(SD) model that analyzed causal relationships between physical inactivity rates, the number of deaths, medical expenses, and total social costs. Simulation period of SD was from 2009 to 2030. Three alternatives were proposed with combinations of length of bike lanes, number of bus routes, crime rates, self-reported good health status rates, and obesity rates. The total estimated cost of physical inactivities from 2009 to 2030 was 31.9 trillion won from the future forecast without policies. As a result of simulations with three alternatives, there were economic benefit approximately from 119.7 billion won to 1.16 trillion won. This study contributed to better understanding the economic benefits of healthy cities that were associated with design of built environment and physical activity. It also emphasized the importance of healthy cities planning as one of national welfare polices.

This study was performed to investigation of the serum alpha-fetoprotein (AFP) levels in healthy adults. A total of 2,160 (male 1,415, female 745) health checkup adults were examined for AFP levels by chemiluminescence immunoassay (CLIA) method, during the period from September, 2007 to August, 2008. The mean serum AFP level was 2.168 (0.605~20.35) ng/mL, and it was 2.309 (0.605~20.35) ng/mL in male, 1.906 (0.605~10.36) ng/mL in female, respectively. 1,816 (male 1,109, female 709) healthy adults were screened for the absence of viral hepatitis and normal alanine amino transferase (ALT) levels. The mean serum AFP level of healthy adult was 2.041 (0.605~7.83) ng/mL, and it was 2.181 (0.605~7.83) ng/mL in male, 1.822 (0.605~6.55) ng/mL in female, respectively. Serum AFP increased with age group, there was a higher level in male compared to female. These results suggests that the use of reference value of AFP in healthy adults in the Jeonbuk. With the reference value now defined, it becomes possible to compare levels in different populations.

Purpose: This study was to compare the effect of center of pressure(COP) displacement and muscle activation onset during expected and unexpected sudden limb loading in subjects with low back pain and healthy control subjects. Most studies of COP displacement and muscle activation onset on postural task focused on sudden trunk loading or gross limb movements. Investigation of the COP displacement and muscle activation onset during expected and unexpected sudden upper limb loading deserves similar attention. Methods: For this study, 14 subjects with low back pain and 12 healthy control subjects are participated. Force plate and surface EMG measures were used to determine COP displacement and muscle activation onset under expected and unexpected sudden upper limb loading. Results: COP displacement and muscle activation onset under unexpected sudden upper limb loading were similar in subjects with low back pain and healthy control subjects. However, COP displacement and muscle activation onset under expected sudden upper limb loading were shortened in healthy control subject but not among the subjects with low back pain. Conclusion: The results provide evidence for impaired feed-forward control in subjects with low back pain.

Systemic lupus erythematosus (SLE) is a systemic inflammatory autoimmune disease characterized by abnormalities in T cell immunoregulation and hyperreactivity of B cells, leading to autoantibody production and multiorgan injuries. We investigated the effect of baicalin on aberrant immunoregulation in pristane-induced lupus mice. Mice received i.p. a single injection of 0.5 ml of pristane or PBS, and approximately 3 months later, were used as a pristane-induced lupus model or healthy controls. The pristane-induced lupus mice and healthy mice were randomly divided into three groups: healthy mouse group (healthy control), pristane-primed lupus control group (lupus control), and baicalin (BAC)-treated pristane-primed lupus mouse group (BAC-treated lupus). The pristane-induced lupus mice and healthy mice were administrated orally with BAC 50 mg/kg or PBS once in a day for 10 ds. These results demonstrated that levels of serum IL-6, LPS-induced production of IL-6, $PGE_2$ and NO by macrophages, $PGE_2$-stimulated production of IL-6 by macrophages and IFN-${\gamma}$ by thymocytes, and an overexpression of splenic NKT cells and CD69+CD4+ T cells were downregulated in BAC-treated lupus compared to lupus control, while reduced apoptosis of splenic CD4+ T cells were upregulated. Therefore, these findings suggest that BAC may attenuate autoimmunity and disease activity in lupus via downregulation of aberrant activation of T cells and inhibition of overproduction of IL-6 and $PGE_2$ in pristane-induced lupus mice.

This study investigated the correlations of five constructs - health concerns, healthy eating practices and attitudes, food choice motives, attitudes toward organic foods - in the formation of behavioral to the purchasing intentions of organic foods. An instrument encompassing health perception, attitudes, habits and personal traits was developed through the comprehensive reviews of the literature and the assured validity and internal reliability of the contents. The questionnaire was administered to the students of three universities at Daegu, Kyungpook province. A total of 288 questionnaires were collected for a response rate of 96.0%. The correlations of five constructs and purchasing intention were tested simultaneously using structural equation modeling. Healthy eating practices and attitudes toward organic foods were found to be the determinants which directly influence the intention to purchase organic foods. Health concerns didn't show direct relation to the purchasing intention of organic foods. The hypothesized path from the health concerns to the purchasing intentions was not supported. The results indicated that food choice motives and healthy eating attitudes should be managed to achieve higher behavioral intention to purchase organic foods.

BACKGROUND/OBJECTIVES: Obesity is a serious concern worldwide, for which the restaurant industry holds partial responsibility. This study was conducted to estimate restaurant consumers' intention to select healthy menu items and to examine the relationships among behavioral beliefs, past behaviors, attitudes and behavioral intentions, which are known to be major determinants of consumer behaviors. SUBJECTS/METHODS: An online, self-administered survey was distributed for data collection. The study sample consisted of customers who reported having visited casual dining restaurants in the last three months at the time of the survey. Structural equation modeling was used to verify the fit of the proposed research model. RESULTS: Structural equation modeling revealed that the proposed model supports the sequential, mediated (indirect) relationships among behavioral beliefs, past behaviors, attitudes and behavioral intentions toward healthy menu selection. CONCLUSION: This study contributes to the available literature regarding obesity by adding past behaviors, one of the most influential variables involved in prediction of future behaviors of consumers, to the TPB model, enabling a better understanding of restaurant consumers' rational decision process regarding healthy menu choices. The results of this study provide practical implications for restaurant practitioners and government agencies regarding ways to promote healthy menus.

The purpose of this study is to estimate the effects of healthy city policies on residents' walking. In order to estimate promotion of walking rates by healthy cities policies, it developed System dynamics(SD)-based model which showed causal relationships among urban design, public health policies, and walking levels. SD technique is useful for future forecast and policy impact assessment. The spatial units of the SD-based system for policy impact assessment included 66 cities, counties, and communities in Seoul Metropolitan Area. The system simulation was planned to be run for 21 years from 2009 to 2030. For this study, 3 alternatives were proposed with combinations of length of bike lanes, number of bus routes, crime rates, self-reported good health status rates, and obesity rates. As a result of simulations, residents' participation rates for walking were increased from 1.00% to 9.98%. This study contributes to better understanding the benefits of healthy cities that are associated with individual walking. It further provided useful insights into planners' role in promoting health. The paper concluded with a discussion on future research opportunities and implications for public policies in urban and transportation and public health.

Objective: The aim of this study was to asses individual, organizational and environmental capacity for members of Healthy Cities Partnership (KHCP) and exploring advanced suggestions for further developing. Methods: Participants were 27. The questionnaire was developed based on Health Promotion Capacity Checklist and it analyze capacity in 3 lelvels including individual, organizational and environmental. Each level is consist of 4 sections, individual: 'Knowledge', 'Skills', 'Commitment' and 'Resources', organizational; 'Commitment', 'Culture', 'Structure' and 'Resources', environment:'Public opinion', 'Political will', 'Supportive organizations' and 'Ideas and other resources'. Each section was assessed in 4 point rating scale and cross analyzed with basic information. Results: The mean score of 3 levels were 2.57. Among the 3 levels, 'Individual' marks 2.78 point which were top and 'Organizational' marks 2.59 and 'Environmental' marks 2.33. There were no significant factors affecting Healthy cities capacity of 'Individual' and 'Organizational' level, but just 'specialization' of 'Environmental' had significance. Conclusion: Above the results, this study suggested that just 'Individual' capacity is above median point and other levels were lower. Further efforts for developing Healthy cities capacity, especially focused on 'Organizational' and 'Environmental' levels, is strongly required.
