BACKGROUND/OBJECTIVES: Curfew due to the coronavirus disease 2019 (COVID-19) pandemic could influence health behaviors in people, especially in children, who can easily acquire unhealthy eating habits. This study aimed to investigate the effect of COVID-19 on weight, health behaviors including eating habits, physical activity, and sedentary behavior in children aged 6-15 years in Saudi Arabia. SUBJECTS/METHODS: We conducted a cross-sectional online survey that included 280 children aged 6-15 years in Saudi Arabia during the COVID-19 curfew. The survey included questions on sociodemographic characteristics, anthropometric measures, and health behaviors including eating habits, physical activity, and sedentary behavior. RESULTS: We observed a significant difference in the body mass index before and after the COVID-19 pandemic (P < 0.001). Children significantly tended to skip breakfast, along with a decreased intake of dairy products and fast food (P < 0.001). Moreover, children were less physically active and significantly tended to be involved in leisure screen-based activities, including watching TV and use of computer/games (P < 0.001). CONCLUSIONS: This study provides evidence for the negative influences of the COVID-19 curfew on health behaviors, including eating habits, physical activity, and sedentary behavior in children in Saudi Arabia.

Whether the $FTO$ polymorphisms interact with environmental factors has not yet been evaluated in associations with metabolic syndrome (MS) risk. The present study investigated the association of the $FTO$ rs9939609 genotypes, body mass index (BMI), and lifestyle-related factors including smoking, alcohol drinking, physical activity, and diet with MS incidence. A population-based prospective cohort study comprised 3,504 male and female Koreans aged 40 to 69 years. At the beginning of the study, all individuals were free of MS and known cardiovascular disease. Incident cases of MS were identified by biennial health examinations during a follow-up period from April 17, 2003 to April 15, 2009. Pooled logistic regression analysis was applied to obtain relative odds (RO) of MS with its 95% confidence interval (CI). After controlling for potential MS risk factors, we observed no association between the rs9939609 genotypes and MS incidence. In analysis stratified by BMI, however, carriers with the $FTO$ risk allele whose BMI is $29kg/m^2$ or greater showed an approximately 6-fold higher RO (95% CI: 3.82 to 9.30) compared with non-carriers with BMI less than $25kg/m^2$. In particular, the association between the rs9939609 variants and MS risk was significantly modified by high BMI (P-value for interaction < 0.05). Such significant interaction appeared in associations with central obesity and high blood pressure among the MS components. Because carriers of the $FTO$ risk alleles who had BMI of $29kg/m^2$ or greater are considered a high risk population, we suggest that they may need intensive weight loss regimens to prevent MS development.

We performed this study to examine lifestyle patterns and dietary behavior based on the level of Internet addiction of Korean adolescents. Data were collected from 853 Korean junior high school students. The level of Internet addiction was determined based on the Korean Internet addiction self-scale short form for youth, and students were classified as high-risk Internet users, potential-risk Internet users, and no risk Internet users. The associations between the students' levels of Internet addiction and lifestyle patterns and dietary behavior were analyzed using a chi-square test. Irregular bedtimes and the use of alcohol and tobacco were higher in high-risk Internet users than no risk Internet users. Moreover, in high-risk Internet users, irregular dietary behavior due to the loss of appetite, a high frequency of skipping meals, and snacking might cause imbalances in nutritional intake. Diet quality in high-risk Internet users was also worse than in potential-risk Internet users and no risk Internet users. We demonstrated in this study that high-risk Internet users have inappropriate dietary behavior and poor diet quality, which could result in stunted growth and development. Therefore, nutrition education targeting high-risk Internet users should be conducted to ensure proper growth and development.

Public health system and public health practice have changed over the past decades as the result of social and epidemiologic changes. New public health concept emphasizes leadership, strategical thinking, systematic planning and effective performance to identify and solve complex health problem In Korea, the role of Health Center has been expanded rapidly. However there is strong suspicion that Health Center can achieve their mission. This paper aims at understanding what is the needed functions of Health Center and which of its aspects needs improvement. The main results of this study are summarizes as follows. District Health Law does not address the core functions of Health Center. The staffs of Health Center have difficulties in prioritizing their services. The recent attempt to restructure Health Center and change delivery pattern of public health services ended with only limited success. To effectively confront threats to the public's health, the three major function of Health Center must be ${\circled}1$ modifying individual behavior and lifestyle, ${\circled}2$ improving social and economic conditions, and ${\circled}3$ reforming health policies. Better results do not come from setting new functions only; they come from understanding and improving the processes that will then leads to better outcome. We recommend that policy-makers focus economic evaluation of public health programs, building and spreading of the scientific evidence of programs, linkage of public health research and public health program. The criteria of delegation of public health service to private sector is urgently needed. Making community health information data available on a routine basis to providers, managers and researchers of public health services helps promote the efficiency of the overall operation of public health system.

There has recently been an increased interest in women's health from, various disciplines, with different perspectives presented according to each profession's academic background. This has led to many instances of incorrectly defining, or misinterpretation, of the issues even among professionals. Nurse scholars as well as practitioners who work in women's health care need to have a clear conceptual understanding of women's health in order to build a body of knowledge, delineate curricular activities, and set directions for professional nursing interventions. In addition, a conceptual model that may be directly utilized in practice is needed to maintain and promote women's health issues. The purpose of this study was to apply a Hybrid model, analyzing conceptual definitions and discussions related to women's health gathered from review of the literature. Further to compare analyticals the concepts and properties observed from field work, so as to present a final definition of women's health and, build a conceptual framework for a united comprehensive perspective on the concept as well as on nursing practice. Data collection and analysis consisted of a theoretical stage, field work stage, and final analysis. A heterogeneous group of professionals and lay persons, 39 in all, participated in the field work. Study findings Include several subconcepts under the concept of women's health : a woman's whole life, holistic health, quality of life, awareness of being a woman, individual nursing, self care ability, reproductive health, and family health. Thus, a comprehensive definition was built, 1. e., "Women's health care be defined as improvement in the quality of life of women through attainment of holistic health throughout the life span. With reproductive health at the core, the concept is directly related to family and national health, and includes taking care of one's own health based on awareness of being a woman and utilizing self care activities. Women's health care issues are unique and allow various responses, therefore women's health professionals need to apply individual approaches to reach solutions in attaining holistic health and improving quality of life." The constructual factors of women's health were found to be reproductive functions, diseases more common in woman, self actualization, mental health, women's health policies, sexuality, midlife changes, and marital relations, with each factor having more than three properties. Positive factors affecting women's health were found to be a normal childbearing process, a healthy lifestyle, active health management, health information, support, and resources, and interpersonal relationships. Negative factors were found to be overwhelming role stress, cultural oppression, gender inequality, distorted sexual identity, economic difficulties, misuse and/or abuse of substances, and stress. The model of women's health may be visualized as a balance scale set upon a woman's life, supporting 4 concentric circles. The innermost circle and second circle incorporate conceptual definitions of women's health, and the outer two circles represent the constructional factors and properties of women's health. Each circle has its own color that symbolizes the conceptual meaning. Positive and negative factors are represented as weights at either end of the scale, and are affected by nursing intervention, i. e., health and wellness increase when positive factors are stronger, whereas disease and illness increase when negative factors are stronger. This model is only a preliminary effort and requires much discussion and testing to be further developed. Continuous research is also required.

Background: Many chronic diseases are associated with the lifestyle such as smoking, alcohol drinking and exercise. Attention is increasingly paid on the effect of exercise for the management of chronic disease these days. Objective: The purpose of this study was to evaluate the status of the smoking habit, alcohol drinking and physical exercise of the patients with chronic diseases. Methods: Total 793 persons(normal:422, chronic disease patients:371) in a hospital were questioned regarding the habits of smoking and alcohol drinking, and a practice of physical exercise in 1999. The patients with chronic illness were divided into three groups(Group I included the patients of hypertension and diabetes mellitus. Group II includes respiratory disease and cancer. Group III included liver disease). The rate of exercise, the rate of smoking cessation and the rate of abstinence were assessed. In logistic regression analysis with each independent variables in each disease groups (I, II and III, odds ratio for the presence of disease was controlled for age and education. Results: The rate of exercise, the rate of smoking cessation and the rate of abstinence was 31.5%, 27.3% and 9.5% in the patients with chronic disease, respectively. In control group, those were 31.5%, 21% and 2.1%, respectively. In logistic regression analysis with exercise as independent variable, odds ratios(95% CI for age and education were significantly high, with smoking cessation, odds ratio for age was high and with abstinence, odds ratio for disease with high in all disease groups. Conclusion: It was suggested that an effort for proper changes of lifestyle related to disease such as smoking, alcohol drinking and exercise should be intervened in the patients with chronic diseases.

BACKGROUND/OBJECTIVES: The increased consumers' interests in health and food safety have increased the demand for organic foods. Many studies have been performed on consumers' purchase intentions for organic foods and their influencing factors, and various studies have shown that the prices of organic foods and the consumers' willingness to pay are important influencing factors. This study examined the payment value of organic foods and agrifood consumer competency index according to the food-related lifestyles in South Korean consumers. SUBJECTS/METHODS: A cross-sectional analysis was performed using the 2019 Consumer Behavior Survey for Food. A total of 6,176 participants aged 19 to 74 years (male: 2,783, female: 3,393) were included in the analysis. RESULTS: Three factors were extracted by factor analysis (rational consumption-seeking type, convenience-seeking type, and health, and safety-seeking type) to explain the consumers' food-related lifestyles. The results of cluster analysis suggested that consumers were classified into 3 food-related lifestyles as the 'exploratory consumers' (n = 2,485), 'safety-seeking consumers' (n = 1,544), and 'passive consumers' (n = 2,147). Exploratory consumers showed a significantly higher willingness to pay for imported organic foods (P < 0.05). Safety-seeking consumers had a significantly higher willingness to pay for domestic organic foods (P < 0.05). For the agrifood consumer competency index, exploratory consumers had the highest score, followed in order by safety-seeking consumers and passive consumers. CONCLUSIONS: These results provide basic data in understanding consumption tendency for organic foods and agrifoods based on food-related lifestyles of South Korean consumers.

Over the last two decades, significant research attention has been given to the acute effect of a single bout of exercise on postprandial lipaemia. A large body of evidence supports the notion that an acute bout of aerobic exercise can reduce postprandial triacylglycerol (TAG) concentrations. However, this effect is short-lived emphasising the important role of regular physical activity for lowering TAG concentrations through an active lifestyle. In 1995, the concept of accumulating physical activity was introduced in expert recommendations with the advice that activity can be performed in several short bouts throughout the day with a minimum duration of 10 minutes per activity bout. Although the concept of accumulation has been widely publicised, there is still limited scientific evidence to support it but several studies have investigated the effects of accumulated activity on health-related outcomes to support the recommendations in physical activity guidelines. One area, which is the focus of this review, is the effect of accumulating exercise on postprandial lipaemia. We propose that accumulating exercise will provide additional physical activity options for lowering postprandial TAG concentrations relevant to individuals with limited time or exercise capacity to engage in more structured forms of exercise, or longer bouts of physical activity. The benefits of accumulated physical activity might translate to a reduced risk of cardiovascular disease in the long-term.

Objectives: The purpose of this study was to examine the health promoting lifestyle(HPL) practices and to provide the baseline data for development of church setting-centered health promotion program. Methods: For the study, 315 adults were selected from a church in G city by convenient sampling method. The data were analyzed using frequencies, ANOVA, t-test, Duncan test, and Pearson's correlation coefficient with the SPSS/PC program. Results: The mean score on HPL was 3.3. The item of the lowest score HPL was smoking. In the mean score of knowledge, behavior, and practice on HPL, the highest score of knowledge on HPL was drinking, but the highest score of practice was smoking. On the other hand, the highest score of behavior was: exercise, nutrition, stress respectably. Analysis of HPL according to the demographic characteristics showed there was a statistically significant difference by age. Subcategories of HPL showed positive correlations statistically significant: Exercise with nutrition, stress and drinking. Nutrition with stress and drinking. Drinking with stress and smoking. Conclusions: Based on the above findings, it is suggested to develop church setting-centered health promotion program with areas focused on management of stress, antismoking, sobriety, practice in nutrition and exercises.

Anecdotal reports indicate that maladaptive patterns of Internet use constitute behavioral addiction. Internet addiction is characterized by unrestrained and awfully controlled engrossment or behaviors regarding internet access that lead to impairment, stress, dimensionally measured depression, indicators of social separation and anguish. By reviewing and analyzing approximately 100 articles we present evidence that are able to provide an overview of the main themes and proclivity covered by existing and relevant studies. The vital detection of this research unveils that many factors related to social, demographic, lifestyle changes related constructs have a bearing on the phenomenon of internet addiction strongly. This study not only reached certain conclusions for both theory and practice, but also defined future lines of research according to the gaps detected by the study's results. The main findings from this literature, though not conclusive, but will help the researcher and policymakers to obtain a better understanding and description of the problem faced by the youth and necessary to develop some remedies to lessen the addiction phenomenon.
