Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

School Feeding Programs in the United States during 1853-2010 / 中国学校卫生

Abstract@#The Children s Aid Society of New York has been providing free food to students at local vocational schools since 1853. It wasn t until 1975 that the school lunch program was permanently mandated by Congress. The National School Lunch Program in America has gone through a historic process from its inception and establishment to its development. The continued interest and oversight of the American people, public opinion guidance by progressive people like nutrition reformers, home economics and other are external factors in the continued development of this program. The timely enactment of the bill by the federal government and the high concern of senior leaders on this project is an important prerequisite for continued development. Integrating this program into the national agricultural development strategy and realizing the overall development philosophy is the key to the sustainability of this program. Paying attention to children s physical health is the core reason why American School Feeding Programs focus on children s diet quantity to children s nutritional quality. All of these factors contribute to the development of this project.
