Methods Ninety one randomly selected schoolchildren were divided into three groups according to their iron status. Iron status including hemoglobin （Hb）, serum ferritin （SF）, serum iron （SI） and sTfR was determined. Physical performance tests included maximum oxygen consumption （VO2max） and maximum work time. Energy expenditure （EE） and daily physical activity were estimated by recording 24-h heart rate （HR）. Dietary intake was assessed with frequency questionnaires, and physical activity level was estimated with frequency and physical activity questionnaires. Results Severe iron deficiency （IDA） impaired the aerobic capacity and habitual physical activity. When fat-free mass （FFM） was considered, VO2max （VO2max/FFM） was significantly lower in the iron-marginal group than in the iron-adequate groups among girls （P=0.02）, but such a deference was not found among boys （P=0.28）. Aerobic activity and EE at leisure were significantly lower in the severe iron deficient group than in the marginal iron deficient and iron adequate groups. Net HR at leisure time was correlated with lib, log SF, body weight, and FFM （P〈0.05）. Conclusion The functional effect of iron deficiency on physical performance and habitual physical activity rely on the degree of current iron deficiency. Severe iron deficiency significantly impairs both aerobic capacity and habitual physical activity. Iron-marginal deficiency impairs VO2max/FFM in girls, rather than in boys.展开更多

Countries and places have introduced a number of policies to address the issue in a timely manner. At first, this paper analyzes the compulsory education policy for migrant workers＇ children and off-site college entrance policy, then find that there are still many problems in the formulation and implementation of policy. In the future, the relevant departments should be through improving the social status of migrant workers, increasing efforts to support the private school children of migrant workers, increasing investment in adult education, increasing the publicity of city, such the four aspects of policy guidance to coordinate and solve the education of migrant workers＇ children.展开更多

The municipal govemment of Beijing has decided that beginning in September, public schools in the Chinese capital should become more open to eligible migrant children by lowering the charges, and qualified social organizations and individuals will be allowed to run schools for migrant children in migrant population communities in light of the standard of average local public schools.展开更多
