Health behaviors influence health and well-being, improve quality of life, and provide economic benefits. It is important to take advantage of health-related opportunities during adolescence. Staying healthy during adolescence also promotes the future well-being of individuals and that of the next generation. We aimed to develop a reliable and valid scale based on the General Senior High School Physical Education and Health Curriculum Standards (2017 edition) to evaluate Chinese late adolescents’ health behavior. The scale was to help physical education teachers measure the health behavior level of senior high school students, improve physical education and health teaching, and promote Chinese adolescent health. Participants were recruited by convenience sampling from September to October 2019. For the first survey, we recruited 526 senior high school students (318 boys, 208 girls; Mage = 16.5), and the data were subjected to item analysis and exploratory factor analysis. For the second survey, we recruited 542 senior high school students (249 boys, 293 girls; Mage = 15.5), and the data were subjected to confirmatory factor analysis and internal consistency reliability analysis. After exploratory factor analysis, we extracted four factors with 23 items: exercise awareness and habits (five items), mastering and applying healthy behavior knowledge (10 items), emotional regulation (four items), and environment adaptation (four items). The Cronbach’s alpha values for these factors ranged from 0.863 to 0.937. After confirmatory factor analysis, we achieved a satisfactory goodness-of-fit model (CMIN/DF = 2.92, RMR = 0.03, GFI = 0.93, CFI = 0.91, TLI = 0.92, RMSEA = 0.06). Internal consistency, test–retest reliability, and construct validity were all satisfactory. These results suggest that the Chinese version of the Health Behavior Scale is a reliable and valid instrument for assessing the health behavior of senior high school students. The findings have important implications for increasing adolescents’ health literacy, promoting adolescents’ health, and enhancing the well-being of late adolescents.

Since the founding of the People's Republic of China, China's civil aviation industry has been developing rapidly and occupies an important position in the country's economy and transportation, at the beginning of 2020, the world broke out in a large-scale epidemic -- COVID-19. During this period, all walks of life suffered a huge impact. A large number of enterprises went bankrupt due to high risk and insufficient response capacity. What are the major effects on the financials of company and what are the main reasons that cause this substantial change? With the liberalization of national policies and the transformation of the epidemic, tourism has gradually recovered. Nowadays, this kind of topic becomes more and more popular, some people have become interested in what’s going on of the airline company especially the stocks. To see how the China Southern airline worked and operated to affect the financials during COVID-19, that is the reason why this paper needs financial analyze to tell people.

Applying the visualized bibliometric analysis method, we explored the overall distribution characteristics, research progress, and hotspots of current research on the effect of the built environment on the physical activity of children and adolescents from 2003 to 2022. The research results indicate that the United States, Canada, Australia, and other Western countries are the primary forces of relevant research and have a solid foundation in the research on the impact of the built environment on the physical activity of children and adolescents. Sallis, Saelens, Gile-Corti, and other early authors have had a long-term, important role in this area. The research results have continuously guided new scientific research output for a long time, and emerging research forces have also played a directional role in future research trends, represented by publications such as American Preventive Medicine and Preventive Medicine. Obesity, health behaviors, home–school environment, and various correlations are the research hotspots in this field. This study systematically summarizes and analyzes research on the built environment’s promotion of physical activity among children and adolescents, and it provides valuable guidance and reference for follow-up research in the near future.

Background Health behaviors shape health and well-being, improve life quality, and provide economic benefit. Adolescence is a life phase in which the opportunities for health are great. Adolescent health brings not only the benefits of the present but also the well-being of the future and the next generation. We aimed to develop a reliable and valid scale that was used to evaluate the health behavior of the late adolescent, namely, the senior high school student. Methods In this study, we conducted two surveys: For the first survey, we recruited 526 senior high school students (318 boys, 208 girls; Mage = 16.5), and the data were used for item analysis and exploratory factor analysis. For the second survey, we recruited 542 senior high school students (249 boys, 293; girls; Mage = 15.5), and the data were used for confirmatory factor analysis and internal consistency reliability analysis. Results In exploratory factor analysis, we extracted four factors with 23 items in all: exercise awareness and habits (5 items), master and apply healthy behavior knowledge (10 items), emotional regulation (4 items), and environment adaptation (4 items). The Cronbach’s alpha values of the factors ranging from 0.863 to 0.937. A satisfactory goodness of fit model was achieved (CMIN/DF = 3.18, RMR = 0.04, GFI = 0.90, CFI = 0.92, TLI = 0.91, RMSEA = 0.06). Conclusions These results suggest that the Chinese version of the Health Behavior Scale is a reliable and valid instrument for assessing the health behavior of senior high school students.
