Over the last few decades, the rates of pediatric obesity have more than doubled regardless of sociodemographic categorization, and despite these rates plateauing in recent years there continues to be an increase in the severity of obesity in children and adolescents. This review will discuss the pediatric obesity mediated cardiovascular disease (CVD) risk factors such as attenuated levels of satiety and energy metabolism hormones, insulin resistance, vascular endothelial dysfunction, and arterial stiffness. Additionally, early intervention to combat pediatric obesity is critical as obesity has been suggested to track into adulthood, and these obese children and adolescents are at an increased risk of early mortality. Current suggested strategies to combat pediatric obesity are modifying diet, limiting sedentary behavior, and increasing physical activity. The effects of exercise intervention on metabolic hormones such as leptin and adiponectin, insulin sensitivity/resistance, and body fat in obese children and adolescents will be discussed along with the exercise modality, intensity, and duration. Specifically, this review will focus on the differential effects of aerobic exercise, resistance training, and combined exercise on the cardiovascular risks in pediatric obesity. This review outlines the evidence that exercise intervention is a beneficial therapeutic strategy to reduce the risk factors for CVD and the ideal exercise prescription to combat pediatric obesity should contain both muscle strengthening and aerobic components with an emphasis on fat mass reduction and long-term adherence.

Purpose: The purpose of this study was to examine the influence of appearance stress, job-seeking stress, and college life stress on eating attitude in nursing students. Methods: Data were collected in September and October of 2017. A total of 153 fourth-year nursing students were included in the analysis. Descriptive statistics, t-test, ANOVA, correlation and multiple regression analysis were conducted using SAS 9.2. Results: The mean score for eating attitude was 2.71±0.56. From the univariate analysis, appearance, job-seeking, and college life stress scores were all significantly related to eating attitude (r=.26, .35, .30 respectively, and p for all <.001). After controlling for covariates, job-seeking stress and college life stress were significantly related to eating attitude (β=.20 and 0.17 respectively, and p=.005 and .024 respectively). Among the covariates, experience of diet and physical anxiety were significantly associated with eating behavior (β=.33 and .24 respectively, and p<.001 and .008 respectively). Conclusion: Job-seeking stress had the biggest influence on eating attitude, followed by college life stress. Therefore, in order to promote healthy eating attitudes in fourth-year nursing students, preventive measures focusing on decreasing job-seeking stress should be considered as a top priority.

Background: The Slender racer (Orientocoluber spinalis Peters, 1866) has recently been reclassified to the new genus Orientocoluber from Hierophis. Ecological knowledge of this species is limited due to its highly mobile behavior. On 17 July 2020, we captured a female O. spinalis on Oeyeon Island, Boryeong-si, Republic of Korea, and collected its feces for a diet analysis. We observed snake scales from the collected feces and subsequently determined the prey species through morphological and molecular methods. Results: We initially hypothesized that the extracted fecal sample scales belonged to H. vibakari, due to their thin keel and rhombus shape. We also amplified H. vibakari DNA from the extracted fecal sample using Illumina sequencing methods. Our morphological and molecular results suggest that O. spinalis predates H. vibakari on Oeyeon Island. Conclusion: This is the first report of O. spinalis predating another snake species, ophiophagy, and implies that H. vibakari may be a crucial prey item for O. spinalis on Oeyeon Island.

Purpose: This study investigated childhood cancer survivors' behavior related to a healthy lifestyle during their survival period by comparing reports between childhood cancer survivors and their parents. Methods: In this comparative descriptive study, a survey was conducted with a 33-item questionnaire and one open-ended question about areas for improvement. The participants comprised 69 childhood cancer survivors and 69 of their parents, for a total of 138. Results: The total mean healthy lifestyle score, on a 4-point Likert scale, reported by childhood cancer survivors was 2.97, while that reported by their parents was 3.03. No significant differences in children's healthy lifestyles were found between childhood cancer survivors' and their parents' reports (t=0.86, p=.390). For the open-ended question, the main keywords based on the results of degree and eigenvector centrality were "exercise", "unbalanced diet", and "food". These keywords were present in both the children's and parents' responses. Conclusion: Obtaining information on childhood cancer survivors' healthy lifestyles based on reports from themselves and their parents provides meaningful insights into the improvement of health care management. The results of this study may be used to develop and plan healthy lifestyle standards to meet childhood cancer survivors' needs.

Purpose: Motivated by the fact that Malaysians fish consumption patterns and preferences have raised sustainability concerns, this study aims to understand the key entry points to promote sustainable consumption and increased uptake of sustainably sourced fish among Malaysian consumers. This is achieved by exploring the individual determinants of Malaysian consumers' fish purchasing behaviors and their subjective and objective knowledge of fish. Research design, data, and methodology: A survey was conducted using interviewled questionnaire on 250 consumers in selected Malaysian populations recruited via street-intercept random sampling. Results: Findings confirmed the homogeneous societal culture of fish consumption amongst Malaysians. Females and consumers with advanced degree are found to be potentially effective primary targets of sustainable consumption interventions. Future interventions should consider the solutions to the low health and sustainability literacies among Malaysian consumers, and limited availability, accessibility, and affordability of sustainable options in Malaysia. Conclusion: The study findings provide new insights for the multisectoral stakeholders in the region working on promoting sustainable fish consumption and sustainable fisheries in general.

This study examined whether the perceptions of the theory of planned behavior (TPB) and individual and environmental factors related to healthy eating changed after the COVID-19 pandemic among adults living in Daqing, China. Data were collected through two rounds of online surveys conducted from April to May 2021 and from March to April 2023, using a questionnaire previously validated for use in Daqing. Using the snowball sampling method, 571 adult participants were recruited, most of whom were Daqing oilfield workers or members of their families. Multiple linear regression analyses were used to determine if the differences in the perceptions of the TPB and dietary environments exist during and after the pandemic after controlling for potential confounders. Scores of several subcomponents of TPB and mean scores of longterm intentions increased but scores of subcomponents and overall mean of motivation decreased after the outbreak. Multiple linear regression showed that only motivation for healthy eating decreased after the pandemic. Influenced by the pandemic, people increased their healthy eating behaviors. Nevertheless, as the pandemic subsided and the pace of life accelerated, people tended to choose convenient foods over healthy options. Consequently, the motivation for healthy eating has declined post-pandemic compared to during the pandemic.

Purpose: Influenza is the most common seasonal infectious disease that causes permanent social, economic, and medical problems worldwide. Therefore, the most effective way to prevent influenza is through vaccines. The aim of this study is to identify the influence of factors that determine the refusal of influenza vaccine among three subjects groups. Materials and Methods: A survey was conducted amongst the three high-risk groups in 2018-2019 (Moscow, Russia). The survey involved 1,620 parents and pregnant women (group 1), 324 doctors (group 2), and 433 students (group 3). Poor vaccine uptake was observed among respondents in all three groups. Results: According to the survey results, only 22.2% of children and 13.8% of adults were vaccinated against influenza. Group 2 showed increased rates with 36.7% of vaccinated adults and 58.7% of children. The lowest adherence to annual vaccinations was recorded in group 3 (only 17.3%). There is also a negative correlation between adherence to vaccination and smoking (-0.66), unhealthy diet (-0.73), poor oral hygiene (-0.61), and insufficient awareness of the need for influenza vaccine as well (-0.81). Conclusion: Thus, a general lack of vaccination awareness has a fundamental role in forming a negative attitude toward influenza vaccine. It is necessary to conduct research to promote vaccination against influenza to improve vaccine uptake among high-risk groups, particularly students.

The purpose of this study was to provide basic data necessary for creating a more successful health enhancement program, health education and health policy which can enhance health management abilities and enable a healthy school life by examining relations between high school students' health perception, who are in early adolescence, and their health promotion behavior. The subjects in this study were 813 students from 8 high schools on Jeju Island. The collected data were analyzed with t-test and one-way ANOVA through questionnaires by researcher on the basis of advance research. The findings of this study were as belows : 1. When general characteristics were considered, health perception was more significantly affected by those who were boys, whose family income was on a higher level, who scored better in school, whose parents were more concerned about their children's health, and who had experiences of being hospitalized. Especially, the more parents were concerned about their children's health, the higher the child's self-confidence on health(p<.05), anxiety on health(p<.05), practicality on disease prevention(p<.05), self-confidence on future health(p<.01), health care ability(p<.01), and family roles on health(p<.05). The less parents were concerned about their children's health, the higher the child's anxiety on disease(p<.01) and uncertainty on future health(p<.01). 2. When students' health promotion behavior was concerned, in the area of Eating Habits, having regular meals(72.9%), moderate consumption of meat(89.7%) and a balanced diet(64%) were common, whereas having a regular breakfast(37.4%) and eating vegetables and fruits(43.6%) were rare. In the area of Exercise, all subareas such as exercising 3 or 4 times a week(76.7%), more than one hour of exercise at a time(74.9%), a short distance walk(51.8%), exercise within one hour after meals(87%), and whether wanning up or not(88.6%) were above average. In the area of Personal Hygiene, all subareas such as drinking boiled water(57.3%), washing hands after using the bathroom(71%), brushing teeth after eating(42.4%), washing up after going out(50.3%), and washing hair and taking a frequent bath(77.2%) were rare. In the area of Control of Personal Relations, consulting personal problems with family(78.7%) had a positive response, whereas meeting someone new(59.8%), maintaining sound relations with the opposite sex(47.3%), having respect for one's opinion(51.5%), and maintaining peaceful relations with people(58.4%) had rare negative results. In the area of Stress Management, not being competitive(69.4%), releasing problems(62.4%) and sleeping soundly(66.2%) were common, whereas having your own ways to relieve stress(46.8%) and having your own dreams and hopes(58.5%) were rare. 3. When general characteristics were considered, as far as relations of health promotion behavior were concerned, the boys were significantly different in the area of Eating Habits(p<0.01) and Exercise(p<0.01), and the girls were in the area of Personal Hygiene. As family economic status was high and parents were concerned about their children's health, the entire areas of health promotion behavior were significantly different. Whether or not they were hospitalized made no significant difference in statistics. 4. When their regions were considered, it comparing city to town, there was no statistically significant difference in health perception and relations of health promotion behavior according to general characteristics. As seen in the results above, high school students' level of health perception and level of practicing health promotion behavior were generally low. In conclusion, by enhancing health perception, a plan for activating health education, which can implement positive health promotion behavior, should be made.

Nutritional regulation of gene expression associated with growth and feeding behavior in avian species can become an important technique to improve poultry production according to the supply of nutrients in the diet. Insulin-like growth factor-I (IGF-I) found in chickens has been characterized to be a 70 amino acid polypeptide and plays an important role in growth and metabolism. Although it is been well known that IGF-I is highly associated with embryonic development and post-hatching growth, changes in the distribution of IGF-I gene expression throughout early- to late-embryogenesis have not been studied so far. We revealed that the developmental pattern of IGF-I gene expression during embryogenesis differed among various tissues. No bands of IGF-I mRNA were detected in embryonic liver at 7 days of incubation, and thereafter the amount of hepatic IGF-I mRNA was increased from 14 to 20 days of incubation. In eyes, a peak in IGF-I mRNA levels occurred at mid-embryogenesis, but by contrast, IGF-I mRNA was barely detectable in the heart throughout all incubation periods. In the muscle, no significant difference in IGF-I gene expression was observed during different stages of embryogenesis. After hatching, hepatic IGF-I gene expression as well as plasma IGF-I concentration increases rapidly with age, reaches a peak before sexual maturity, and then declines. The IGF-I gene expression is very sensitive to changes in nutritional conditions. Food-restriction and fasting decreased hepatic IGF-I gene expression and refeeding restored IGF-I gene expression to the level of fed chickens. Dietary protein is also a very strong factor in changing hepatic IGF-I gene expression. Refeeding with dietary protein alone successfully restored hepatic IGF-I gene expression of fasted chickens to the level of fed controls. In most circumstances, IGF-I makes a complex with specific high-affinity IGF-binding proteins (IGFBPs). So far, four different IGFBPs have been identified in avian species and the major IGFBP in chicken plasma has been reported to be IGFBP-2. We studied the relationship between nutritional status and IGFBP-2 gene expression in various tissues of young chickens. In the liver of fed chickens, almost no IGFBP-2 mRNA was detected. However, fasting markedly increased hepatic IGFBP-2 gene expression, and the level was reduced after refeeding. In the gizzard of well-fed young chickens, IGFBP-2 gene expression was detected and fasting significantly elevated gizzard IGFBP-2 mRNA levels to about double that of fed controls. After refeeding, gizzard IGFBP-2 gene expression decreased similar to hepatic IGFBP-2 gene expression. In the brain, IGFBP-2 mRNA was observed in fed chickens and had significantly decreased by fasting. In the kidney, IGFBP-2 gene expression was observed but not influenced by fasting and refeeding. Recently, we have demonstrated in vivo that gizzard and hepatic IGFBP-2 gene expression in fasted chickens was rapidly reduced by intravenous administration of insulin, as indicated that in young chickens the reduction in gizzard and hepatic IGFBP-2 gene expression in vivo stimulated by malnutrition may be, in part, regulated by means of the increase in plasma insulin concentration via an insulin-response element. The influence of dietary protein source (isolated soybean protein vs. casein) and the supplementation of essential amino acids on gizzard IGFBP-2 gene expression was examined. In both soybean protein and casein diet groups, the deficiency of essential amino acids stimulated chickens to increase gizzard IGFBP-2 gene expression. Although amino acid supplementation of a soybean protein diet significantly decreased gizzard IGFBP-2 mRNA levels, a similar reduction was not observed in chickens fed a casein diet supplemented with amino acids. This overview of nutritional regulation of IGF-I and IGFBP-2 gene expression in young chickens would serve for the establishment of the supply of nutrients to diets to improve poultry production.
