Objective To study the physical activities for myopia in children. Methods ICF theory and literature research were used to analyze the current status of myopia in children, as well as the related factors, and mechanisms of formation and improvement, and discussed the physical activity for their visual function and overall development. Results Myopia was epidemic and began in low ages. The related factors mainly included focus time, less in physical activities, stress in education and poor vision environment. Myopia happened through the ciliary muscle spasm and synergistic dysfunction. Physical activity played a role like adjustment function training to improve the function of ciliary muscles, and promote the development of vision.Conclusion Development of special physical activities based on the theory of ICF may improve the visual function in children and promote their overall development.

Objective To investigate the developmental characteristics of static visual acuity (SVA) and kinetic visual acuity (KVA) and the correlation between the for children. Methods From April to June, 2018, SVA and KVA of 715 children aged 6 to 10 years in Suzhou were tested with logarithmic visual chart and KVA meter. Results KVA and SVA increased with age within 6 to 9 years old, and decreased then. KVA was higher in boys than in girls (t = 4.604, P < 0.001), but not significantly different for SVA (t = 1.822, P > 0.05). There was a moderate positive correlation between KVA and SVA (r = 0.552, P < 0.01). KVA can predicted SVA (B = 0.617, P < 0.001). Conclusion KVA and SVA develop for children aged 6 to 9, and moderately positive correlate with each other. It means SVA may be improved via training of KVA.

Objective To systematically research the policies and core contents of World Health Organization (WHO) and United Nations Educational, Scientific and Cultural Organization (UNESCO) documents on policies, guidelines and standards for health-promoting schools and health services. Methods These policy documents included Making Every School a Health-promoting School: Implementation Guidelines, WHO Guidelines on School Health Services, and Making Every School a Health Promoting School Global Standards and Indicators, which construct a conceptual and policies framework for health-promoting schools. In perspective of health service system, this study systematically explored the policies, guidelines and standards of WHO and UNESCO on health-promoting schools and health services, as well as the role of health-promoting school component systems in promoting the health of children and how physical activity can be an important area of health-promoting schools. Results The Health Promoting Schools Initiative is an important area of research for the WHO health services. Making Every School a Health-promoting School: Implementation Guidelines primarily serves students aged five to 19, teachers and other staff in schools. WHO Guidelines on School Health Services cover a variety of activity types including health promotion, health education, preventive interventions, clinical assessment and health services management. Making Every School a Health Promoting School Global Standards and Indicators covers eight global criteria and thirteen specific areas in the areas of policy resources, curriculum and environment, and community engagement. Conclusion WHO and UNESCO have proposed a series of policies related to building health-promoting schools, which focus on child health and advocate the promotion of child and adolescent health, public health, education, social and economic development through schools to achieve the goal of safeguarding the health rights of children and adolescents and meeting health needs. Following the WHO Guidelines on School Health Services and Making Every School a Health Promoting School Global Standards and Indicators, it proposed to incorporate educational and physical education tools into the school health service system.
