Objective To explore the iron intake of children from different sources and assess the iron status of children. Methods A total of 1 600 children aged 3~12 years old were selected through multiple stage stratified cluster sampling from 6 cities and 2 rural areas of China.General information and 24 h dietary recalls were obtained by questionnaire. Results The overall dietary iron intake was (14.3±8.3)mg/d,with a median of 12.4(9.5,16.6) mg/d.The overall animal source iron intake (meat,eggs and milk) was (2.6±2.8)mg/d,with a median of 2.2(1.1,3.48) mg/d.The overall plant source iron intake was (10.4±7.8) mg/d,with a median of 8.6(6.1,12.0) mg/d.The overall Animal Source Food Ratio (ASFR) was 18.6%.There were 278 (17.4%) children with iron intake lower than EAR,and 47 (2.9%) children with iron intake higher than UL.The proportion of children with iron intake lower than EAR in Chengdu was the lowest (6.3%),while the proportion of children with iron intake higher than UL in Xingtai mountain area was the highest (7.7%).ASFR of rural children was significantly lower than urban level.The most important food source for dietary iron was cereals and meat. Conclusion The iron intake of children in China is relatively low,much attention should be paid to improve animal source iron intake of children in rural areas.
